Title: Compositions and Products for Infectious or Inflammatory Diseases or Conditions Claim of Priority

This application claims priority to U.S. Provisional Patent Application Serial No. 61/792,984, filed March 15, 2013, entitled "Compositions and Products for Infectious or Inflammatory Diseases or Conditions", the entire specification and disclosure of which is herein incorporated by reference.

Field of Invention

The present disclosure relates generally to the fields of compositions and products containing the compositions, and the use of the compositions or the products for preventing and/or treating infectious or inflammatory diseases or conditions in particular gastrointestinal and respiratory diseases (diarrhea and influenza infections) or inflammatory. More specifically, the present disclosure relates to the compositions of oral rehydration salt or oral rehydration solution (ORS) and the use of the ORS for the prevention and treatment of dehydration due to diarrhea or fever. More specifically, the present disclosure relates to the methods of preparing and using the compositions or the products containing the compositions.

Background

An infectious disease is a clinically evident disease of humans or animals. Information collected by the World Health Organization (WHO) on global deaths shows that worldwide mortality due to infectious diseases is as high as 25.9% of all deaths, or 14.7 million deaths in 2002 (WHO World Health Report 2002). The current numbers are even higher.

Influenza infections especially an influenza pandemic threats people's health and economy globally. There is a big concern on a possible influenza pandemic causing by highly pathogenic H5N1 (avian or bird) influenza virus which will cause much more deaths than the 2009 swine influenza pandemic (WHO). Currently, there are no effective medicines for the treatment of a serious condition of an influenza infection especially a serious condition after 48 hours of an influenza infection.

The estimated annual incidence of diarrheal diseases by the World Health Organization (WHO) was as high as -4.51 billion. In 2009 diarrhea was estimated to have caused 1.1 million deaths in people aged five and over and 1.5 million deaths in children under the age of five. Rotaviruses are a leading cause of severe diarrheal disease and dehydration in infants and young children throughout the world especially the third world. Diarrheal diseases are serious problems in animal field too and negatively impact the agriculture-food economy, food safety, public health and the environment.

There is no specific medical treatment for rotavirus infection and other viral diarrhea thus far. Oral rehydration therapy (ORT) with oral rehydration solution (ORS) is now routinely used to correct the fluid and electrolyte losses caused by diarrhea or fever. ORS is used to correct the symptom of dehydration due to diarrhea but does not have anti-diarrheal action (reduced volume and duration).

Farmers routinely give antibiotics to food-producing animals to treat illnesses (e.g. diarrhea), prevent infection and encourage growth. However, mounting evidence indicated that overuse of antibiotics could induce a global crisis of antibiotic-resistant bacteria that do not respond to medical treatment and endanger human lives. The European Union banned the feeding of antibiotics and related drugs to livestock for growth promotion in 2006. The US Food and Drug Administration (FDA) urged farmers to stop giving antibiotics to cattle, poultry, hogs and other animals to spur their growth. Non-antibiotic products capable of replacing antibiotics for the uses mentioned above are needed. Summary of the Invention

While the present disclosure is susceptible of embodiment in many different forms, there will be described herein in detail, preferred and alternate embodiments of the present disclosure. It should be understood however, that the present disclosure is to be considered an exemplification of the principles of the invention and is not intended to limit the spirit and scope of the invention and/or claims of the embodiments illustrated.

Definitions: As used herein:

Infectious diseases: refers to the invasion of a host organism's bodily tissues by disease- causing organisms, their multiplication, and the reaction of host tissues to these organisms and the toxins they produce. A short-term infection is an acute infection. A long-term infection is a chronic infection. Pathogens specific to infectious diseases suitable for use in this process include, but are not limited to viruses, bacteria, parasites, fungi, viroids, prions, protozoa, and insects, and etc., without limitation. Examples of infections include but not limited to the disorders caused by influenza viruses, reoviruses, rotaviruses, cytomegaloviruses (CMV), Epstein-Barr viruses (EBV), adenoviruses, hepatitis viruses including HAV, HBV, HCV, human immunodeficiency virus (HIV), human T-cell leukemia viruses (HTLV), human papilloma viruses (HPV), polio viruses, parainfluenza viruses, measles viruses, mumps viruses, respiratory syncytial viruses (RSV), human herpes viruses (HHV), herpes simplex virus (HSV), Varicella-Zoster Virus, cholera viruses, pox virus, rabies virus, distemper virus, foot and mouth disease viruses, rhinoviruses, Newcastle disease viruses, pseudorabies virus, cholera, syphilis, anthrax, leprosy and bubonic plague, rickettsias, neisseria gonorrhoeae, bordetella pertussis, escherichia coli, salmonella enterica, vibrio cholerae, pseudomonas aeruginosa, yersinia pestis, francisella tularensis, haemophilus influenzae, purple sulfur bacteria, helicobacter pylori, Campylobacter jejuni, bacillus anlhracis/cereus/thuringiensis, Clostridium tetani, Clostridium botulinum, staphylococci, streptococci, pneumococci, streptococcus pneumoniae, mycoplasmas, bacteroides fragilis, mycobacterium tuberculosis, mycobacterium leprae, corynebacterium diphtheriae, treponema pallidum, borrelia burgdorferi, chlamydia trachomatis, chlamydia psittaci, phycocyanin, phycoerythrin, mitochondria, chloroplasts, etc without limitation.

Inflammation: refers to the complex biological response of vascular tissues to harmful stimuli, such as pathogens, damaged cells, or irritants. The classical signs of acute inflammation are pain, heat, redness, swelling, and loss of function. Although infection is caused by a microorganism, inflammation is one of the responses of the organism to the pathogen. However, inflammation is a stereotyped response, and therefore it is considered as a mechanism of innate immunity. Inflammation can be classified as either acute or chronic. Acute inflammation is the initial response of the body to harmful stimuli and is achieved by the increased movement of plasma and leukocytes (especially granulocytes) from the blood into the injured tissues. A cascade of biochemical events propagates and matures the inflammatory response, involving the local vascular system, the immune system, and various cells within the injured tissue. Prolonged inflammation, known as chronic inflammation, leads to a progressive shift in the type of cells present at the site of inflammation and is characterized by simultaneous destruction and healing of the tissue from the inflammatory process. Progressive destruction of the tissue would compromise the survival of the organism. However, chronic inflammation can also lead to a host of diseases, such as hay fever, periodontitis, atherosclerosis, rheumatoid arthritis, and even cancer (e.g., gallbladder carcinoma). Examples of inflammation include but not limited to Alzheimer's, ankylosing spondylitis, arthritis (osteoarthritis, rheumatoid arthritis (RA), psoriatic arthritis), asthma, atherosclerosis, Crohn's disease, colitis, dermatitis, diverticulitis, fibromyalgia, hepatitis, irritable bowel syndrome (DBS), systemic lupus erythematous (SLE), nephritis, Parkinson's disease, ulcerative colitis, etc without limitation.

The respiratory tract: refers to the structures of the anatomy involved with the process of respiration. The respiratory tract is divided into 3 segments: upper respiratory tract including nose and nasal passages, paranasal sinuses, and throat or pharynx; respiratory airways including voice box or larynx, trachea, bronchi, and bronchioles; and lungs including respiratory bronchioles, alveolar ducts, alveolar sacs, and alveoli. Most of the respiratory tract exists merely as a piping system for air to travel in the lungs, and alveoli are the only part of the lung that exchanges oxygen and carbon dioxide with the blood. The respiratory tract is a common site for infections. Upper respiratory tract infections are probably the most common infections in the world.

Respiratory diseases or conditions: refers to an abnormal status or conditions of the upper respiratory tract, trachea, bronchi, bronchioles, alveoli, pleura and pleural cavity, and the nerves and muscles of breathing. Respiratory diseases range from mild and self-limiting. Respiratory diseases can be classified as many types. Inflammatory lung disease include but not limited to asthma, cystic fibrosis, emphysema, chronic obstructive pulmonary disorder or acute respiratory distress syndrome. Obstructive lung diseases include but not limited to chronic obstructive pulmonary disease (COPD), which includes emphysema and asthma. Asthma is a difficulty in breathing causing wheezing due to inflammation of bronchi and bronchioles, this causes a restriction in the airflow into the alveoli. Respiratory tract infections can affect any part of the respiratory system. The upper respiratory tract infection include but not limited to common cold, sinusitis, tonsillitis, otitis media, pharyngitis and laryngitis. The lower respiratory tract infection include but not limited to pneumonia, a lung infection. Pneumonia is usually caused by bacteria, particularly Streptococcus pneumoniae in Western countries. Worldwide, tuberculosis is an important cause of pneumonia. Other pathogens such as viruses and fungi can cause pneumonia for example severe acute respiratory syndrome and Pneumocystis pneumonia. A pneumonia may develop complications such as a lung abscess, a round cavity in the lung caused by the infection, or may spread to the pleural cavity. Other examples of respiratory diseases or conditions include but not limited to influenza infections, common cold, entities like viral or bacterial pneumonia, pulmonary embolism, and lung cancer. Gastrointestinal diseases or conditions: refers to an abnormal status or function of the esophagus, stomach and intestine. Examples of gastrointestinal diseases or conditions include but not limited to diarrhea, gastroenteritis, ileitis, colitis, coeliac disease, inflammatory bowel disease, Crohn's disease and ulcerative colitis, irritable bowel syndrome (IBS), chronic functional abdominal pain, pseudomembranous colitis, esophagitis, gastritis, esophageal cancer, gastric cancer, intestinal cancer, colon cancer, and colorectal cancer,

Diarrhea: diarrhea is defined by the WHO as having three or more loose or liquid stools per day, or as having more stools than is normal for that person. The same definition is also suitable for animals.

Diarrhea may be caused by an infection or a chronic gastrointestinal disease. The common causes of diarrhea include but not limited to: 1) bacterial infections such as infections caused by Clostridium, Campylobacter, Salmonella, Shigella, Giardia and Escherichia coli; 2) Viral infections such as infections caused by rotavirus, coronavirus, Norwalk virus, cytomegalovirus, herpes simplex virus and viral hepatitis; 3) nutritional problems or food intolerances.

The possible mechanisms of action

Many microbes bind to mammalian tissues by recognizing specific saccharide ligands. Thus saccharides and saccharide mimetics can be used to block the initial attachment of microbes to cell surface or block their release thus prevent and/or suppress infection (anti- adhesive). Because one of these organisms (e.g. rotavirus) naturally gains access through the gut, the saccharide-based drugs can be delivered directly without the requirement of being distributed systemically. Examples of such applications currently under study include milk oligosaccharides that are believed to be natural antagonists of gastrointestinal infection in infants; and polymers that will block the binding of viruses (Ajit Varli et al.. Essentials of Glycobiology, Second Edition. Cold Spring Harbor Laboratory Press, 2008: pp730).

The present invention discloses using sialic acids as a possible agonist or antagonist by possibly competing with natural viral binding sites of pathogens using sialic acids as their binding sites such as receptors (e.g. rotaviruses or influenza viruses). The application of N- acetylneuraminic acid (Neu5Ac) and N-acetylneuraminic acid methyl ester for the prevention and treatment of rotavirus and influenza infections are described in Exemplification.

In addition, chemical modification of sialic acids can strongly influence all of their properties, in particular ligand functions. For example, O-methylation can hinder or even prevent hydrolysis of the glycosidic bond by sialidase. Other substitution of the hydroxyl groups of sialic acids arise from use of the appropriate donors. For example, S- adenosylmethionine for methylated sialic acid or 5'-phosphosulfate for sulfated molecules (Ajit Varli et al.. Essentials of Glycobiology, Second Edition. Cold Spring Harbor Laboratory Press, 2008: pp207).

One embodiment of the present invention is using methyl- and sulfur-containing molecules as donors for methylation and sulfatation of sialic acids or other saccharides. For example, methionine contains -S-CH3 thus may act as a donor to modify a pathogen binding site (a sialic acid or a saccharide) into methylated and sulfated forms. Such chemical modification of a sialic acid or a saccharide may attenuate even prevent pathogen binding to it.

Numerous other objects, features and advantages of the present disclosure will become readily apparent from the detailed description.

6. Methods of uses

6.1 Prevention and treatment of rotavirus infection with formulations

Preparation of formulations

One package of formula- 1.1 mixture consisted of 1.0 gram of N-acetylneuraminic acid and 27.9 grams of oral rehydration salt mixture (as described at 1.1 of the Exemplification) was dissolved in 1000 ml of sterilized water (formula- 1.2).

One package of formula-2.1 mixture consisted of 1.0 gram of N-acetylneuraminic acid, 1.0 gram of methionine and 27.9 grams of oral rehydration salt mixture (as described at 2.1 of the Exemplification) was dissolved in 1000 ml of sterilized water (formula-2.2).

One package of formula-3.1 mixture consisted of 1.0 gram of N-acetylneuraminic acid, 1.0 gram of N-acetylneuraminic acid methyl ester and 27.9 grams of oral rehydration salt mixture (as described at 3.1 of the Exemplification) was dissolved in 1000 ml of sterilized water (formula-3.2).

One package of formula-4.1 mixture consisted of 1.0 gram of N-acety euraminic acid, 0.5 gram of metnionine, 0.5 gram of N-acetylneuraminic acid methyl ester and 27.9 grams of oral rehydration salt mixture (as described at 4.1 of the Exemplification) was dissolved in 1000 ml of sterilized water (formula-4.2).

One package of formula-5.2 mixture consisted of 0.1 gram of N-acetymeuraminic acid,

0.1 gram of metnionine and 27.9 grams of oral rehydration salt mixture (as described at 5.2 of the Exemplification) was dissolved in 1000 ml of sterilized water (formula-5.4).

One package of a regular oral rehydration salt mixture consisted of 3.5 grams of sodium chloride, 1.5 grams of potassium citrate, 2.9 grams of sodium citrate, and 20 grams of glucose in a total amount of 27.9 grams was dissolved in 1000 ml of sterilized water (ORS alone).

A commercially available antibiotic Enrofloxacin for the treatment of animal diarrhea was prepared as a solution at the concentration of 1 mg/ml with the ORS solution as a vehicle.

The formulations of 1.2, 2.2 and 3.2 were used for the treatment of rotavirus infection. The regular ORS alone and the Enrofloxacin were used as controls. In addition, combination use of formula 1.2 and the Enrofloxacin was also tested for the treatment of rotavirus infection.

Six groups of sucking bulb/c mouse pups with body weight of about 2 grams were inoculated at day 2 after birth (P2) with 20 μΐ (microliter) of rhesus rotavirus (RRV) at the concentration of 1 x 10 ⁷ PFU/ml, followed by being treated once per day at day 3 (P3) via oral administration with 50 μΐ (microliter) of: 1) the ORS alone (control, n = 51); 2) the Enrofloxacin alone (antibiotic control, n = 52); 3) the formula- 1.2 (n = 21); 4) the formula- 2.2 (n = 50); 5) the formula-3.2 (n = 20); and 6) the formula- 1.2 and the Enrofloxacin (50μ1 + 50μ1) (n = 21). Mice were kept for 3 weeks after RRV infection.

The course of rotavirus infection is that within week 1 after RRV infection, the pups have diarrhea with watery stools, don't eat well and fail to gain weight as quickly as healthy mice; and some pups with serious illness become jaundiced. By the 2nd week all the mice become jaundiced, don't eat well and fail to gain weight; about 30% of pups with symptoms of infection die and 80% of pups with serious illness die. Viruses are usually cleared and undetectable within one week. An effective result of a treatment was judged by reduced volume and duration of diarrhea, and reduced deaths.

Although all the formulas tested showed efficacy for treating rotavirus infection, formula-2.2 showed the best efficacy (92.0%) (Table 1). The diarrhea of the pups treated with the formular-2.2 was lighter and lasted only 1-2 days; the diarrhea of the pups treated with either ORS alone or Enrofloxacin was serious and lasted 3-4 days (Table 1). In addition, only one pups treated with the formula-2.2 died while 15 and 12 pups of the ORS- or enrofloxaci- treated pups died (Table 2). The data showed that formula-2.2 significantly reduced the death rate of rotavirus infection. Further, the combination use of formula- 1.2 comprising N- acetymeuraminic acid and Enrofloxacin significantly increased the efficacy or reduced the toxicity of the antibiotic.

The effective dosages of the formulas for the treatment of rotavirus infection of other organisms including humans are from 0.1 mg/kg to 100 mg/kg of N-acetylneuraminic acid or methionine or N-acetylneuraminic acid methyl ester. The effective dosages of Enrofloxacin can be reduced to 1/4 - 3/4 of the amounts instructed by the manufacture when it is used in combination with N-acetylneuraminic acid.

6.2. Treatment of piglet diarrhea with formulations

Diarrhea is a common disorder with sucking or weaning piglets. Viral or bacterial infections are common causes of piglet diarrhea. Piglets with viral diarrhea usually have yellow watery stools and piglets with bacterial diarrhea usually have gray stools. Sometimes, yellow diarrhea is accompanied with vomiting showing the characteristic of infective gastroenteritis. Often, piglet diarrhea or infective gastroenteritis is caused by mixed infection of viruses and bacteria. Piglets younger than one week could have a serious viral diarrhea or infective gastroenteritis with high death rates from about 70% to over 90%.

The formulations of 1.2, 2.2, 3.2 and 4.2 as prepared above in 6.1 were used for the treatment of diarrhea piglets at ages 1-5 days. The ORS alone and the Enrofloxacin were used as controls. In addition, combination of formula 1.2 and Enrofloxacin was also used for the treatment of piglet diarrhea.

Seven groups of sucking piglets with yellow watery diarrhea or infective gastroenteritis at ages of 1-5 days were treated once per day via oral administration or muscular injection with: 1) 1 ml/kg of body weight of ORS alone (control group, n = 50); 2) Enrofloxacin according to manufacture's instruction (antibiotic control, n = 69); 3) 1 ml/kg of body weight of the formula- 1.2 (n = 49); 4) 1 ml/kg of body weight of the formula-2.2 (n = 82); 5) 1 ml/kg of body weight of the formula-3.2 (n = 55); 6) 1 ml/kg of body weight of the formula-3.2 (n = 51); and 7) 1 ml/kg of body weight of the formula-1.2 plus Enrofloxacin (n = 32).

76 out of 82 (92.7%) and 46 out 51 (90.2%) of piglets treated with formula-2.2 and formula-4.2 stopped diarrhea within 24 hours after one dose treatment; while majority of piglets treated with Enrofloxacin stopped diarrhea at day 4-5 after treatment with one dose treatment every day. Over 80% of piglets treated with formula-1.2 or formula-3.2 stopped diarrhea within 24-48 hours after 1-2 dose treatment. In addition, the combination use of formula-1.2 comprising N-acetylneuraminic acid and Enrofloxacin significantly increased the efficacy or reduced the toxicity of the antibiotic. The death rates of piglets with different treatments of formulations are concluded in Table 3.

6.3. Treatment of piglet diarrhea with formulations

The formula-2.2 as prepared above in 6.1 was used for the treatment of diarrhea piglets at ages 5-40 days.

Two groups of sucking or weaning piglets with various diarrheas or infective gastroenteritis at ages of 5-40 days were treated once per day via oral administration with: 1) Enrofloxacin according to manufacture's instruction (antibiotic group, n = 139); and 2) 1 ml/kg of body weight of the formula-2.2 (n = 262).

Over 90% of piglets treated with formula-2.2 stopped diarrhea within 24 hours after one dose treatment; while majority of piglets treated with Enrofloxacin stopped diarrhea at day 4- 5 after 4-5 dose treatment (one dose every day). The results are concluded in Table 4. The data indicated that the formula-2.2 comprising N-acetylneuraminic acid and methionine effective for the treatment of various diarrheas caused by viruses and bacteria.

6.4. Prevention of gastrointestinal and respiratory diseases of piglet with formulations The formulations of 1.2, 2.2, 3.2 and 4.2 as prepared above in 6.1 were used at age of day 5 for the prevention of piglet diarrhea. The ORS alone was used as control.

Five groups of healthy sucking piglets at age of day 5 were treated once per day via oral administration with: 1) 1 ml/kg of body weight of ORS alone (control group, n = 126); 2) 1 ml/kg of body weight of the formula- 1.2 (n = 19); 3) 1 ml/kg of body weight of the formula- 2.2 (n = 160); 4) 1 ml/kg of body weight of the formula-3.2 (n = 18); and 5) 1 ml/kg of body weight of the formula-4.2 (n = 46). The piglets were observed for the symptoms of diarrhea and other diseases up to day 40.

During the period of observation, all the formulas tested showed significant efficacies for the prevention of piglet diarrhea compared to the ORS control (Table 5). The piglets treated with formula-2.2 or formula-4.2 showed the lowest diarrhea frequencies (11.3% and 8.70%, Table 5). In addition, the diarrhea of the piglets treated with the formulations was lighter and lasted only 1-2 days. The diarrhea of the piglets treated with ORS alone was serious and lasted 3-4 days. The results are concluded in Table 5.

During the period of observation, an outbreak of foot and mouth disease virus (FMDV) infection occurred. The piglets treated with formula-4.2 did not infected with the FMDV; the other piglets treated with formula-2.2, formula-3.2 were infected with significantly reduced frequencies (about 20%) without any deaths compared to the piglets without treating with any formulas (99%). In addition, some of the piglets without treating with any formulas infected with porcine circovirus (PCV) during the period of observation while none of the piglets treated with formulas were infected with PCV. Further, during the period of observation, majority of piglets treated with the formulations did not show the symptoms of other diseases such as diarrhea, gastroenteritis, asthma, respiratory infections or other disorders. The data indicated that the formulations of the present invention are effective for the prevention of various gastrointestinal and respiratory infections and other diseases including but not limited to diarrhea caused by viruses or bacteria, infective gastroenteritis, asthma, respiratory syndrome, other viral infections such as FMDV and PCV infections.

In addition, combination use of formula 1.2 or formula 3.2 and the Tamiflu was also used for the treatment of influenza infection of mice.

Seven groups of newborn bulb/c pups were inoculated at day 5 (P5) via oral and nasal administration of 30 microliter of the A/PR 8/34(HlNl) influenza virus strain (titer: 1:512, diluted 100 times with saline); and were treated at day 2, 3, 4 and 5 after the viral infection via intraperitoneal injection with 1) 100 microliter of ORS alone (n = 30); 2) 100 microliter of Tamiflu (2 mg/ml) (n = 30); 3) 100 microliter of formula-3.2 (n = 30); 4) 100 microliter of formula-3.3 (2mg/ml) (n = 30); 5) 100 microliter of formula-1.2 plus 100 microliter of Tamiflu (2 mg/ml) (n = 21); and 6) 100 microliter of formula-3.2 plus 50 microliter of Tamiflu (2 mg/ml) (n = 21). Mice were kept for 7 days after infection.

The results are listed in Table 7. 26/30 (86.7%) of mice treated with ORS alone and 70% of the mice treated with Tamiflu died during the course of the influenza infection. The death rates of the pups treated with formula-3.2 and formula-3.3 were reduced to 23.3% and 40% respectively. In addition, the combination use of Tamiflu and N-acetylneuraminic acid or N-acetylneuraminic and N-acetylneuraminic acid methyl ester significantly increased the efficacy or reduced the toxicity of the antibiotic compared to the efficacy of Tamiflu alone.

6.7 Treatment of respiratory infections or disorders of piglets with formulas

The formulations of 1.2 and 3.2 as prepared above in 6.1 were used for the prevention and treatment of respiratory infections or disorders of piglets. The ORS alone and a commercially available antibiotic product, Timicosin were used as controls. In addition, combination of formula 3.2 and Timicosin was used for the treatment of respiratory infections or disorders of piglets.

Weaning piglets (10 ~15 kg, aged 5-7 weeks) suffered from respiratory infections accompanied with the respiratory syndrome characterized by asthma-like symptoms (difficulty with breath). The sick piglets were treated separately once a day via oral administration or intramuscular injection with 1) Tilmicosin according to manufacture's instructions (n = 39); 2) 1 ml/kg of body weight of the formula-3.2 (n = 36); and 3) Tilmicosin and 1 ml/kg of body weight of the formula-3.2 (n = 41).

Majority (37/41, 90.2%) of the piglets treated with the formula-3.2 or Tilmicosin plus the formula-3.2 recovered at day four (3 doses); while it took 4-5 doses for the piglets treated with Tilmicosin alone getting recovered. In addition, the death rate of the piglets treated with the formula-3.2 plus Tilmicosin (9.76%) was significantly lower compared with the death rate of the piglets treated with Tilmicosin alone (28.2%) (Table 8).

6.9 Treatment of respiratory infections including influenza of humans with formulas The formula-3.2 as prepared above in 6.1 was used once a day via oral administration for the treatment of eleven human subjects with respiratory infections including influenza infections with the symptoms of coughing, chills, fever, sore throat, runny nose, muscle pains, headache (often severe), weakness/fatigue, etc. The dose was 0.5-1.0 mg/kg body weight.

The symptoms of 10/11 (91%) of the subjected treated with formula-3.2 were significantly reduced, and all the subjects recovered within three days after starting the treatment.

The effective dosages of the formulas for the treatment of respiratory infections including influenza infections of humans are from about 0.1 mg/kg to 100 mg/kg of N- acetylneuraminic acid or N-acetylneuraminic acid methyl ester.

6.10 Prevention and treatment of inflammatory disorders with formulations

The formula-3.2 as prepared above in 6.1 was used via oral administration for the prevention or treatment of human pollen allergy (3), rhinitis (n = 5), sinusitis (n = 2), arthritis (n = 3), essential tremor (n = 2) and Parkinson's disease (n = 1).

The three subjects suffered from pollen allergy every year were treated once a day by nasal (1-2 ml) and oral administration (20-50 ml) of the formula-3.2 during the outbreak season. No significant symptoms of pollen allergy were observed with the three subjects.

The five subjects with rhinitis and the two subjects with sinusitis were treated once a day by nasal (1-2 ml) and oral administration (20-50 ml) of the formula-3.2. About 70% of the symptoms of the rhinitis and sinusitis were significantly reduced within two hours of the treatment.

The three subject with arthritis were treated once a day by oral administration (20-50 ml) of the formula-3.2. Significant pain relief was observed within two hours of the treatment.

The two subjects with essential tremor were treated once a day by oral administration (20-50 ml) of the formula-3.2 or the formula-1.2 or 10-25 ml of the formula-3.3. The trembling width and the frequencies were reduced about 50% after 2-3 days treatment with each the formula respectively.

The subject with Parkinson's disease was treated once a day by oral administration (20- 50 ml) of the formula-3.2. The trembling width and the frequencies were reduced about 50% after 2-3 days treatment with the formula. Taken together, the data indicated that the formulas comprising N-acetymeuraminic acid or N-acetylneuraminic acid methyl ester or N-acetylneuraminic acid and N- acetylneuraminic acid methyl ester have broad effects on the inflammatory disorders, allergy and autoimmune diseases include but not limited to pollen allergy, rhinitis, sinusitis, arthritis, essential tremor and Parkinson's disease.

In addition, combination use of N-acetylneuraminic acid or N-acetylneuraminic acid methyl ester or N-acetylneuraminic acid and N-acetylneuraminic acid methyl ester with other existing therapeutic products for those disorders reduced the adverse reactions or toxicity and increase the efficacy of those products.

The effective dosages of the formulas for the treatment of human inflammatory disorders or conditions are from about 0.1 mg/kg to 100 mg/kg of N-acetylneuraminic acid or N-acetylneuraminic acid methyl ester.

6.11 Prevention and treatment of side effects of interferon with formula-1.2

Three HCV-infected human subjects have the history of interruption of interferon therapy due to the side effects of interferon. The side effects of interferon included nausea, vomiting and upset stomach along with diarrhea or constipation, headache and drowsiness, thinning of the hair, depression, excessive sleepiness and confusion, etc.

The formula-1.2 as prepared above in 6.1 was used once a day via oral administration to the three HCV-infected subjects to prevent and treat the side effects of interferon at the time of their resuming interferon therapy. The doses were 0.5-1.0 mg/kg body weight.

The symptoms of the interferon side effects of the three subjects treated with formula- 1.2 were significantly reduced, and all the subjects finished the entire course of the interferon therapy. The data indicated that N-acetylneuraminic acid can reduce the side effects of interferon.

The effective dosages of N-acetylneuraminic acid for the treatment of side effects of a therapeutic are from about 0.1 mg/kg to 100 mg/kg.

Method of using

Prevention of diarrhea and other diseases of weaning piglets

Weaning pigs: aged at 4-5 weeks and at 1-5 day of feeding with nursery feed.

Test group- 1 : 175 of weaning piglets, fed with nursery feed with formula-6.12.1-3 as mentioned above.

Test group-2: 108 of weaning piglets, fed with nursery feed with fonnula-6.12.1-4 as mentioned above.

Control group: 256 of piglets, fed with nursery feed with ORS alone as mentioned above.

The nursery feeds were given from 1-5 days of the beginning of the nursery feeding. The total feeding days with the nursery feeds were 5-10 days.

The observed results

The piglets treated with the feed with either formula-6.12.1-3 or formula-6.12.1-4 looked healthy with pink skin and shining fur compared to the pigs of the control group. The diarrhea rate of the weaning piglets of the control group was 53.9%; the diarrhea rates of the weaning piglets of the test group-1 and group-2 were 5.71% and 5.56% separately (Table 10). The diarrhea of the two test group piglets was lighter (not water-like diarrhea) compared to the diarrhea of control group piglets (water-like diarrhea). The death rate of the control group piglets was 15.6%. The death rates of the piglets of the two test groups were only 0.06% (group-1) and 1.85% (group-2) separately (Table 11).

The diarrhea piglets of control group were treated with antibiotic (ofloxacin). The piglets treated with antibiotic grew slowly, looks smaller and not healthy. The diarrhea piglets of the test groups were not treated and they did not lose body weight significantly and looked in a good healthy status.

The data indicated that feeding weaning piglets with the feeds with the products comprising N- acelylneurarninic acid and N-acetylglucosamine or N-acetylneuraminic acid and methionine significantly reduced the frequencies of sick and death of weaning infants suffer from respiratory syndrome or asthma. Thus the products comprising N-acetylneuraminic acid and N- acetylglucosamine or N-acetylneuraminic acid can be used for the prevention of respiratory syndrome or asthma and other diseases of weaning infants. The effective dosages of the formulas for the prevention of diarrhea, respiratory syndrome or asthma, and other diseases of weaning infants are from about 0.1 mg/kg to about 100 mg/kg of N-acetylneuraminic acid, N-acetyl glucosamine, or methionine. The amounts of ORS are from about 1 gram to about 5000 grams.

The other diseases of weaning infants include but not limited to respiratory infections, the respiratory syndrome, asthma, the infection of foot and mouth disease virus (FMDV), the infection of porcine circovirus (PCV) and other disorders of weaning infants.

In another two tests, similar results were observed with sows fed with feeds with either formula-6.12.1-3 or formula-6.12.1-4.

The data indicated that feeding pregnant sows with the feeds with either formul-6.13.1-1 , or formul-6.12.1-3, or formula-6.12.1-4 significantly reduced the deaths due to still birth and neonatal death. Thus the products comprising N-acetylneuraminic acid alone, or products comprising N-acetylneuraminic acid and N-acetylglucosamine or methionine can be used for the prevention of still birth and neonatal death of pregnant females.

In addition, feeding pregnant females with the feeds with either formul-6.13.1-1, or formul- 6.12.1-3, or formula-6.12.1-4 also reduced abortion, dystocia, mastitis, infections and other diseases of pregnant and feeding females.

The effective dosages of the products for the prevention of abortion, dystocia, still birth, neonatal death, infections, mastitis, and other diseases of pregnant and feeding females are from about 0.1 mg/kg to about 100 mg/kg of N-acetylneuraminic acid, N-acetylglucosamine, or methionine. The amounts of ORS are from about 1 gram to about 5000 grams.

The other diseases of pregnant and feeding females include but not limited to respiratory infections, the respiratory syndrome, asthma, the infection of foot and mouth disease virus (FMDV), the infection of porcine circovirus (PCV), sudden death without clear causes, various infections and other disorders.

Prevention of diarrhea of newborn piglets by feeding pregnant and feeding sows

Pregnant sows: at 1-10 days before delivery.

Test group- 1: 30 of pregnant sows, fed with lactation feed with formula-6.13.1-1 as mentioned above. Test group-2: 30 of pregnant sows, fed with lactation feed with formula-6.12.1-3 as mentioned above.

Test group-3: 50 of pregnant sows, fed with lactation feed with formula-6.12.1-4 as mentioned above.

Control group: 100 of pregnant sows, fed with lactation feed with ORS alone as mentioned above. c. The lactation or sow feeds were given between 1-10 days before delivery date.

d. The total feeding days with the lactation feeds were 5-10 days.

The observed results

During a outbreak of diarrhea, over 90% of newborn piglets died from serious diarrhea within 5 days after birth. To reduce the death of the newborn piglets, the pregnant sows were treated either with the feed with formula-6.12.1-3, -6.12.1-4, or -6.13.1-1, or with feed mixed with the solutions of formula-2.2, or -6.12.1-2. Although the treatment of pregnant sows did not completely prevented the diarrhea of their newborns (Table 16) the deaths of newborn piglets were significantly reduced (Table 17).
