摘要
Background:Yu-Ye decoction is a classic prescription therapy that is widely used in the treatment of type 2 diabetes mellitus(T2DM).In this study,we evaluate and exhibit the protective effect of modified Yu-Ye decoction on T2DM rats.Methods:Sixty rats with T2DM were included in this study that was induced by high-fat high-glucose diet for 6 weeks.following 6 weeks later,1%streptozotocin 30 mg/kg was injected intraperitoneally,and the T2DM rats were randomly divided into the model group,the metformin(90 mg/kg)positive control group,and the modified Yu-Ye decoction(6.4 g/kg,12.7 g/kg,25.4 g/kg)group.In contrast,standard chow was provided to the 10 rats in the control group.The drug was administered for four weeks,and fasting blood glucose was monitored.After four weeks of treatment,oral glucose tolerance test experiments were carried out.Serum was collected for the detection of alanine aminotransferase,aspartate aminotransferase,creatinine,blood urea nitrogen,low density lipoprotein,high density lipoprotein,and total cholesterol,triglyceride.Hematoxylin-eosin staining was used to assess potential pathological changes in the liver,kidneys,and pancreas.Results:Results from fasting blood glucose monitoring and oral glucose tolerance test showed that modified Yu-Ye decoction could significantly improve the blood glucose concentration and insulin resistance,compared to the model group.In addition,modified Yu-Ye decoction could significantly reduce the serum levels of alanine aminotransferase,aspartate aminotransferase,creatinine,blood urea nitrogen,low density lipoprotein,total cholesterol,triglyceride,and increase the level of high density lipoprotein.At the same time,hematoxylin-eosin results exhibited that modified Yu-Ye decoction could increase the number of islet cells,reduce the volume of islet cells,improve liver edema and inflammation,and improve renal glomerular hypertrophy.Conclusion:This study shows that modified Yu-Ye decoction ameliorates T2DM because it can reduce fasting blood glucose concentration,improve glucose tolerance,protect liver and kidney function,and improve livers,kidneys,and pancreas tissue morphology.
