Effects of Sig Leo Dean on serum ceramide, chemerin, islet function and oxidative stress indexes in T2DM rats

摘要

cqvip:Objective: To investigate the effect of Sig Leo Dean on serum ceramide, chemerin, islet function and oxidative stress index in type 2 diabetes mellitus (T2DM) rats. Methods: Fifty-four SPF male SD rats aged 4 weeks were selected and randomly divided into blank group, model group and treatment group with 18 rats in each group. After feeding with high-fat and high-sugar diet for 6 weeks, the model group and treatment group were given intraperitoneal injection of streptozotocin (STZ) to establish the model of T2DM rats. After successful modeling, the treatment group was given cegliptine 10 mg/kg/d, and the blank group and model group were given the same amount of saline. After 6 weeks, the indicators were tested and compared. Results: Before the intervention, the model group and treatment group rat body weight, FPG, Fins and HOMA-IR were significantly higher than the blank group (P<0.05), model group and HOMA- beta treated rats were significantly lower than that of the control group (P<0.05);after the intervention, FPG, Fins and HOMA-IR were significantly higher than the control group in the treatment group but compared with model group (P<0.05), treatment group, body weight, HOMA- beta is significantly higher than model group but lower than that of the control group (P<0.05);before the intervention, the model group and the serum ceramide, the rats in the treatment group chemerin was significantly higher than that of control group (P<0.05);intervention, serum ceramide, chemerin significantly higher than the control group the treatment group but lower than that of model group (P<0.05);before the intervention, the model group and treatment group rats, the SOD level of GSH-PX was significantly lower than that of the control group (P<0.05);intervention treatment group SOD and GSH-PX Significantly lower than the blank group, but higher than the model group (P<0.05). Conclusion: Western medicine can significantly improve the islet function of T2DM model rats, reduce serum ceramide and chemerin levels, and improve the antioxidant function of rats.
