【Abstract】 By setting up the exhaustive swimming rats model, the activity of liver tissues SOD, the quantity of MDA and the serum GPT are all valued. The results indicates that after the rats take in chitin, their physical ability improves remarkably; the activity of liver tissues SOD appears superior to that of the control group; the quantity of MDA is lower than that of the control group, which shows that chitin enjoys much stronger influence on the anti oxidation and anti free radical. Besides, their ability of counteracting the free radical of liver tissues jumps to a high level. Furthermore, chitin can also been used to protect the integrality of liver cell membrane; to reduce the escape of enzyme from the cell.更多还原
