Drinking green tea can prevent liver fibrosis

The results showed that green tea extract could effectively prevent the development of liver fibrosis Some studies have shown that lipid peroxidation stimulates fibroblasts and liver astrocytes to produce collagen, which plays an important role in the development of liver fibrosis Many studies have reported that green tea has a protective effect on the liver, the mechanism of which is to prevent carbon tetrachloride, cholestasis and alcohol induced liver fibrosis However, in the model induced by dimethylnitrosamine, the liver protective effect of green tea is not clear In the World Journal of Gastroenterology published on November 7, 2009, a research team led by Professor Hong yon Cho of the University of Korea published an article to study the protective effect of green tea extract on rat liver astrocyte line and rat liver fibrosis model induced by dimethylnitrosamine The results showed that green tea extract could effectively prevent the development of liver fibrosis in the rat model induced by dimethylnitrosamine These results were confirmed by liver histology and quantitative detection of liver hydroxyproline (a marker of liver collagen deposition) Green tea extract can inhibit collagen production, reduce collagen deposition and type 1 collagen expression in T6 cells These results suggest that green tea extract can reduce the proliferation of activated hepatic astrocytes, down regulate the expression of collagen composition and type 1 collagen, and thus reduce liver fibrosis The researchers concluded that green tea can protect liver cells and reduce collagen deposition in the liver Green tea is a safe and effective method to improve liver fibrosis.
