5, discuss: hepatic injury is the complex process that is caused by several factors; Bacillus calmette-guerin vaccine (BCG) adds lipopolysaccharide (LPS) to the immunologic liver injury model; Its pathological change is similar with hepatitis B with hepatic injury mechanism, can cause proliferation of fibrous tissue, causes hepatic fibrosis; The interior ALT of cell, AST are overflowed, thereby the content of ALT, AST increase in the blood.
Serological index shows and the present invention to make the Chinese medicine preparation agent of anti-hepatitis damage has the certain protection effect to rats'liver, and along with the increasing of dosage, ALT, AST, TP, A1b almost return to normal level in the cell, and effect obviously is superior to similar positive drug.
In addition, through the pathological section result demonstration of rat, the hepatic injury that positive drug group and test group are treated due to various hepatitis and other reasons has certain curative effect, but the effect of the pathological section of test group treatment hepatic injury obviously is superior to positive drug again.
6, conclusion: Chinese medicine composition provided by the invention, effect with treatment hepatitis B.
In addition; Hepatitis such as general hepatitis A, hepatitis B all are because a variety of causes is encroached on liver like virus, chemical toxicant etc.; Hepatocyte is suffered damage; Cause hepatic fibrosis or hepatocellular degeneration, necrosis etc., above-mentioned pharmacodynamics test is verified, and this Chinese medicine preparation has good effect at aspects such as anti-hepatic fibrosis and the liver protecting and ALT lowering, explains also that therefore this Chinese medicine preparation has certain effect in the various types of hepatitis of treatment.
