[Study on expression of transforming growth factor-beta 3 in the liver tissues]

33 specimens of liver biopsy from patients with different types of viral hepatitis were detected for transforming growth factor-beta 3(TGF-beta 3) by immunohistochemistry. The results showed that TGF-beta 3 mainly distributed in the sinusal walls cells in sinus portal, areas fibrous, septum, hepatocytes in pseudolobes and necrotic areas of severe hepatitis. The expressing intensity of TGF-beta 3, was stronger in the cirrhosis, chronic severe hepatitis than that in the chronic and acute hepatitis. As the expression of TGF-beta 3 increased, the level of serum bilirubin ascended and plasmozyme activity was prolonged. It may be concluded that the expression of TGF-beta 3 is correlated with severe hepatitis and the progress of the liver cirrhosis.
