Objective: To study the proliferation effects of Periplaneta americana extracts (samples I, II, III)on rat hepatic stellate cell lines (HSC-T6)in vitro. Methods: HSC-T6 proliferation under the treatment of Periplaneta americana extracts in different concentration and time was determined by MTT method. Results: Compared with the control group, HSC-T6 proliferation was inhibited by sample I with time dependence and reached the peak at 72 hours with concentration dependence within a certain range. Sample IIshowed the same inhibitory pattern but with less effect. Sample III showed a particular inhibition effect in 24 hours, and no effect at other time points. Conclusion: The samples I, II, III can inhibit hepatic stellate cell proliferation, which may be a potential drug for prevention and treatment of liver fibrosis.
