Preventives/remedies for infection, anti-endtoxin agents, vaccine adjuvants and growth promoters
View Patent ↗A preventive or remedy for infection, an anti-endotoxin agents, a vaccine adjuvants and a growth promoter each comprising a sugar cane-derived extract as an active ingredient which agent is safe to man and animals. Also presented are foods and feeds comprising these agents.
1. A method according for remedying a disease caused by a viral infection in humans or animals comprising the step of:
orally administering an amount of a sugar cane-derived extract comprising a component having a molecular weight of less than 1000 as an active ingredient, to a human or animal after infection with the disease by a Pseudorabies infection, which amount is effective to remedy said disease, and the sugar cane-derived extract is a fraction which absorbs light of a wavelength of 420 nm obtainable by column chromatographic treatment utilizing differences in affinity for an ion exchange resin packed in a column as the fixed carrier, said sugar cane-derived extract containing less saccharide than a composition from which said sugar cane-derived extract is extracted.
2. The method according to claim 1 , wherein the ion exchange resin is a cation exchange resin.
3. The method according to claim 2 , wherein the cation exchange resin is a strongly acidic cation exchange resin.
4. The method according to claim 3 , wherein the strongly acidic cation exchange resin is of a sodium ion form or a potassium ion form.
5. The method according to claim 1 , wherein the ion exchange resin is a gel form resin.
6. The method according to claim 1 , wherein ion exchange chromatographic treatment is carried out in a pseudo moving-bed continuous separation method.
7. The method according to claim 1 , wherein the fraction absorbing light of a wavelength of 420 nm is further treated by electrodialysis to thereby decrease a salt content of the fraction.
8. The method according to claim 1 , wherein the sugar cane-derived extract is administered in the form of a food, which comprises the sugar cane-derived extract.
9. The method according to claim 8 , wherein the food is an animal feed.
10. A method for remedying a disease caused by a viral infection in humans or animals comprising the step of:
administering an amount of a sugar cane-derived extract comprising a component having a molecular weight of less than 1000 as an active ingredient, to a human or animal after infection with the disease by a Pseudorabies infection, which amount is effective to remedy said disease, by a method of administration selected from the group consisting of intravenous, intramuscular, subcutaneous, intracutaneous, intra-abdominal, intra-rectal, hypoglossal and installation, and the sugar cane-derived extract is a fraction which absorbs light of a wavelength of 420 nm obtainable by column chromatographic treatment utilizing differences in affinity for an ion exchange resin packed in a column as the fixed carrier, said sugar cane-derived extract containing less saccharide than a composition from which said sugar-cane derived extract is extracted.
11. The method according to claim 10 , wherein the ion exchange resin is a cation exchange resin.
12. The method according to claim 11 , wherein the cation exchange resin is a strongly acidic cation exchange resin.
13. The method according to claim 12 , wherein the strongly acidic cation exchange resin is of a sodium ion form or a potassium ion form.
14. The method according to claim 10 , wherein the ion exchange resin is a gel form resin.
15. The method according to claim 10 , wherein ion exchange chromatographic treatment is carried out in a pseudo moving-bed continuous separation method.
16. The method according to claim 10 , wherein the fraction absorbing light of a wavelength of 420 nm is further treated by electrodialysis to thereby decrease a salt content of the fraction.
17. The method according to claim 10 , wherein the sugar cane-derived extract is administered in the form of a food, which comprises the sugar cane-derived extract.
18. The method according to claim 17 , wherein the food is an animal feed.
