1、Antipyretic and Analgesic Activity
Resveratrol is therapeutic in several different ways. It appears to have antipyretic and analgesic activities, as studied in intact mice and rats (Lin & Hsu, 1987). The extracts appeared to confer protection of the gastric membrane against stress ulcers by slight inhibition of gastric secretion without effect on blood pressure.
2、Anti-cancer and Anti-mutagen Activity
Resveratrol exhibits cancer chemo-preventive activity by acting as an antioxidant, an antimutagen, and an anti-inflammatory agent. It also induces human promyelocytic leukemia cell differentiation (anti-progression activity) and inhibits the development of preneoplastic lesions in mouse mammary glands. Resveratrol can also inhibit protein-tyrosine kinase, which catalyzes the phosphorylation of tyrosine. This kinase is involved in signal transduction in the cytoplasm of a cell involved in the regulation of mitogenesis. The inhibition of protein-tyrosine kinase by resveratrol is possibly antimutagenic by detering the kinases function.
3、Prevention of Heart and Liver Damage
Resveratrol inhibits the deposition of triglycerides and cholesterol in the liver of mice. It also reduces the elevation of aspartate transaminase and alanine transaminase by inhibiting lipid peroxidation in the livers of rats. Analysis of these two enzymes in blood serum gives good diagnostic information for heart and liver damage.
4、Antithrombotic Activity
Resveratrol inhibits lipoxygenase production, which are enzymes found in leukocytes, the heart, brain, lung, and spleen. Thus resveratrol prevents the formation of blood clots within blood vessels. It also inhibits platelet aggregation after treatment with clonidine, an antihypertensive drug.
5、Immune System Improvement in Wound Healing
Resveratrol also promotes healing of burns by enhancing the immune system. Luo (1993) studied the effects of resveratrol on the restoration of suppressed cell-mediated, humoral, and non-specific immune functions in scald mice. Administration of resveratrol provided immuno-modulating effects in a dose-dependent fashion. Lou, et al (1995) showed that resveratrol restored impaired functions, such as response to antigen signal, the proliferative capacity, interleukin II production, and antibody production ability by lymphocytes, in different degrees in severely burned mice. Severely burned animals survived longer while their neutrophil levels and neutrophilic adhesive rates remained near normal due to treatment with resveratrol administered.
