OBJECTIVE To prepare gingerol dropping pills and to investigate its protective effect on alcoholic liver injury. METHODS The prescription was selected by orthogonal design method and the effect of the option and ratio of ground substance,the temperature of drug. The hardness,circular degree,the tail formation and the dissolution time were studied. Totally 40 KM mice were randomly divided into control group,model group,gingerol dropping pill group(400 mg·kg~(-1)·d~(-1)) and positive control group(bifendate,150 mg·kg~(-1)·d~(-1)) of 10 mice each. The mice from the model and two drug groups were administrated with liqueur[0.15 mL/(10 g·d)]daily by gavage for 3 weeks,Two hours later,drug group mice were treated corresponding gingerol dropping pill and bifendate. Meanwhile,the control group were gavaged same amount of normal saline. Finally,when the model of acute alcoholic liver injury was established on the 22 stday,Biochemical indicators of ocular blood in mice were observed.We also observed the change of liver morphology. RESULTS Under optimum conditions,we can obtain dropping pills having circular shape,touching with hardness and short dissolution time. Compared with the control group,the levels of alanine transaminase(ALT),glutamic-oxaloacetic transaminase(AST) and malondialdehyde(MDA) in model group were obviously increased(P<0.01),While the activity of Superoxide dismutase(SOD) were decreased. In addition,In model group,mice liver disorders,hepatic lobule fusion,accompanying a large number of patchy sample liver cell vacuoles,various sizes of fat vacuoles appeared in cytoplasm and inflammatory cell infiltration were visible around the central vein. On the contrary,compared with the model group,drug groups attenuated or even reversed hepatic pathological changes. Form gingerol dropping pill group,an increase in hepatic SOD activity and serum ALT and AST activities were found and a significant decrease in hepatic MDA content were also observed(P<0.01). CONCLUSION The prescription of gingerol dropping pills was reasonable,and the preparation process was simple. Gingerol dropping pills can protect liver from alcoholic liver injury to some extend,and the mechanism may be related to its antioxidant effect.

In addition, In the model group, mice liver disorders, hepatic lobule fusion, accompanying a large number of patchy sample liver cell vacuoles, various sizes of fat vacuoles appeared on the central vein. On the contrary, compared with the model group, drug groups attenuated or versus reversed hepatic pathological changes. , an increase in hepatic SOD activity and serum ALT and AST activities were found and a significant decrease in hepatic MDA content were also observed (P <0.01). CONCLUS ION The prescription of gingerol dropping pills was reasonable, and the preparation process was simple.
