Abstract: Objective To study the preventive and treatment effectsof Scutellaria baicalensis on injured hepatic tissue of rats with acute severe pancreatitis (ASP). Methods Thirty-six Sprague Dawley rats were randomly divided into normal group (normal), ASP group, Bai-pre-ASP group (using Scutellaria baicalensis before acute severe pancreatitis model), Bai-post-ASP (using Scutellaria baicalensis after acute severe pancreatitis model), Bai-pre post-ASP group (using Scutellaria baicalensis before and after acute severe pancreatitis model), and Cef-ASP group (using Cefoperazone after acute severe pancreatitis model). The blood AMY, ALT, IL-6 and nuclear factor (NF)-кB were detected 24 and 48 h after the drugs were given to the rats. The hepatic tissues were also analyzed. The effects of Scutellaria baicalensis on the procedure of acute severe pancreatitis in rats were investigated. Results The activity of AMY, ALT, IL-6 and NF-кB in the ASP group was obviously higher than other groups. Degeneration of hepatic cells, hemorrhage of central veins of hepatic lobules were apparent. The above indexes of the Bai-pre post-ASP group were higher than those of the normal group, but lower than those of other treatment groups. The treatment effect in the Bai-pre-ASP group was similar to that of the Cef-ASP group, and they were better than that of the Bai-post-ASP group in 24 h. However, they were worse than those of the Bai-post-ASP group in 48 h. Conclusions Scutellaria baicalensis has the effects of prevention and treatment on the liver injure of the rats with acute severe pancreatitis. Our research showed that the usage of Scutellaria baicalensis 3 g per 100 g weight before ASP and 5 g per 100 g weight after ASP is appropriate for treatment of liver injury in ASP rats.
