Abstract:The object of this study was to elucidate the effect of Cabbage(thiocyanate) and Beans(flavonoids) extract on the food utilization,liver function and kidney function of rat.For this,The rats divided into different groups according the design of experiment and feeding by different dosage of Cabbage(thiocyanate) and Beans(flavonoids) extract,and then the blood and tissue were extracted after 30 days.It was found that there are without obvious effect on food intake.Compared with the normal control group,single dose of cabbages and beans groups,the joint low-dose group and the joint high-dose group in rats liver coefficient were significantly increased(P<0.05、P<0.01、P<0.05),however,there are no significant effect on kidney coefficient.Compared with the normal control group,each experiment groups ALT/AST are decreased significantly(P<0.01).Compared with the normal control group,it is more significant(P<0.01)in the cabbage group,bean group,middle-dose group(experiment group Ⅱ),high-dose group(experiment group Ⅲ) in rats serum total bilirubin.Compared with the normal control group,single dose of beans groups,the joint low-dose group(experiment group I),the middle-dose group(experiment group II),the joint high-dose group(experiment group III) in rats blood urea nitrogen(BUN) were significantly increased(P<0.05、P<0.01、P<0.05、P<0.05).From the above results,we can draw the conclusion that with thiocyanate,flavonoids increase in food intake,the liver and kidney function were injuries on the body,showing more pronounced in the liver.Also suggested that blindly added thiocyanate,flavonoids will increase the burden of liver and kidney,the potential for thyroid history(hereditary familial,iodine deficiency areas,etc.) people in particular,attention should be paid.
