It was shown that cell proliferation of HL-60 cells was inhibited by S86019 in vitro. Under the action of S86019 the HL-60 cells were induced to differentiate into metamyelocytes, myelocytes and much matured cells with banded or segmented nucleus. Flow cytometry demonstrated that the cell population of HL-60 cells was blocked at G1 phase which resulted in the elevation of percentage of G1 cells and decrease of percentage of cells in S phase. Experimental results demonstrated that S86019 is an active inducer of cell differentiation in HL-60 cells.展开更多

Methods: The anti-inflammatory and analgesic activities were evaluated, using the carrageenan-induced rat paw edema model and the acetic acid writhing test in mice. The gastroprotective activity was determined using HCl/Et OH induced gastric ulcers in rats. The purification and structure elucidation of compound(s) from the more effective fraction were determined by chromatographic and spectroscopic methods and in comparison with data reported in the literature. Results: The fraction F-Et OH showed an important antiinflammatory activity associated with significant analgesic and gastroprotective properties. The purification and structure elucidation of compound(s) from this fraction lead to the identification of one diterpenoid and four sterols. Conclusions: These results suggested that components from the active fraction can be used to treat various anti-inflammatory diseases.展开更多

Animal and epidemiological studies have associated green tea consumption with several health benefits, which include hypocholesterolemic effect and anti-in-flammatory activity. In this study catechins levels of green tea and its effect on the lipid profile of humans were evaluated as well as the protective effects against H2O2-mediated damage in human fibroblasts and anti-inflammatory activity of (–)-epigallocatechingallate (EGCG). The daily consumption of 1200 mL of green tea for 30 days by 15 human volunteers promoted the decrease of cholesterol and LDL levels after 15 days, but this effect was not persistent after 30 days. No changes were observed in lipid profile after the consumption of green tea capsules. EGCG, a major green tea catechin, demonstrated an anti-inflammatory action in rats and an antioxidant effect in cultured human fibroblasts.展开更多
