ABSTRACT
Objective:To study the difference in anti-hepatic fiborsis components between pre-and post-processed Trionyx Sinensis Carapace to guide the clinical application of Trionyx Sinensis Carapace. Methods:SDS-PAGE gel electrophoresis was used to compare the constituents in pre-and post-processed Trionyx Sinensis Carapace, and the inhibitory effect on the proliferation of HSC-T6 was deter-mined by MTT. Results:The processed Trionyx Sinensis Carapace had much more components than the crude Trionyx Sinensis Cara-pace,and the relative molecular mass in the first-level band decreased resulting in the generation of micromolecular polypeptides. Both pre-and post-processed Trionyx Sinensis Carapace had anti-hepatic fibrosis, while the vinegar-processed Trionyx Sinensis was more ef-fective. Conclusion:The difference in the active components in pre- and post-processed Trionyx Sinensis Carapace is obvious, which provides foundation for the clinical application and further researches.
