GPT and Hepatic fibrosis: Further studies showed that RGGs protected liver function and improved pathology by decreasing the CCl4-induced increase in ALT and AST levels in rats and alleviated or even reversed liver fibrosis in rats by decreasing the serum levels of fibrosis markers caused by CCl4, including HA, LN, PC III, HYP, CoII-V, and α-SMA.
