Abstract

The present invention provides novel compositions and methods for repair and regeneration of tissues or organs of the body, especially mucosa in the gastrointestinal tract. The composition can be used as a pharmaceutical or nutraceutical to treat or prevent gastrointestinal cancer such as colorectal carcinoma, stomach cancer and esophagus cancer. The composition is in an oral dosage form and comprises edible oil homogenized with a sterol compound at a concentration of at least 0.5% by weight and edible wax at a concentration ranging from 3% to 30% by weight.

Claims

1. A method for treating a patient having a gastrointestinal cancer, comprising:

orally administering to a patient having a gastrointestinal cancer a composition comprising an edible oil homogenized with an edible wax at a concentration ranging from 0.5% to 50% by weight and a sterol compound at a concentration of at least 0.1% by weight, wherein the edible oil, edible wax and sterol compound are homogenized to form colloid with the edible wax adopting a microcrystal form at ambient temperature.

2. The method of claim 1, wherein the gastrointestinal cancer is an upper gastrointestinal cancer selected from the group consisting of esophagus cancer, stomach cancer, pancreas cancer, liver cancer, and cancer of bile ducts.

3. The method of claim 1, wherein the gastrointestinal cancer is a lower gastrointestinal cancer selected from the group consisting of colorectal carcinoma, primary lymphomas, melanoma, and sarcoma of the large bowel.

4. The method of claim 1, wherein the composition contains less than 1% of water by weight.

5. The method of claim 1, wherein the composition is orally administered in an amount of 0.5-15 g per day.

6. The method of claim 1, wherein the composition is orally administered in an amount of 2-8 g per day.

7. The method of claim 1, wherein the composition is formulated in 0.1-0.5 g soft gel capsules, 1-10 of which are orally administered to the host twice a day.

8. The method of claim 1, wherein the sterol compound is a combination of stigmasterol, β

-sitosterol, and campesterol.

9. The method of claim 1, wherein the sterol compound is β

-sitosterol.

10. The method of claim 1, wherein the edible wax is selected from the group consisting of beeswax, castorwax, glycowax, and carnaubawax.

11. The method of claim 1, wherein the edible oil is selected from the group consisting of corn oil, wheat germ oil, soy bean oil, rice bran oil, rapeseed oil, sesame oil, and fish oil.

12. The method of claim 1, wherein the edible oil is sesame oil.

13. The method of claim 1, wherein the concentration of the sterol compound is 0.5% to 20% by weight.

14. The method of claim 1, wherein the concentration of the sterol compound is 1% to 10% by weight.

15. The method of claim 1, wherein the concentration of the edible wax is 3% to 30% by weight.

16. The method of claim 1, wherein the composition is formulated in a soft or hard gel capsule.

17. The method of claim 1, wherein the composition further comprises baicalin.

18. The method of claim 1, wherein the composition further comprises an extract of huangqin.

19. The method of claim 1, wherein the composition further comprises an extract of a combination of huangqin, huangbai and huanglian.

20. The method of claim 1, wherein the sterol compound is selected from the group consisting of stigmasterol, campesterol, β

-sitosterol, chalinosterol, clionasterol, brassicasterol, α

-spinasterol, daucosterol, desmosterol, and poriferasterol, at a concentration of at least 0.1% by weight based on the total weight of the composition.

21. The method of claim 1, wherein the microcrystal form of beeswax is 0.1-100 μ

m in length.

22. The method of claim 1, wherein the microcrystals of beeswax are dispersed substantially uniformly in the edible oil.
