Abstract:
Objective To investigate the metabolic effects of glucose dependent insulinotropic peptide receptor antagomst pro3 (GIP) in induced diabetes mice about blood glucose,triglyceride,cholesterol,leptin and fatty issue.Methods 27 C57 mice were randomly divided into normal group and diabetes mice group,and the mice in diabetes group were fed with high fat food and intraperitoneal injected streptozocin.Then 1 mouse that random blood giucose lower than 16.9 mmol/L was deleted in diabetes group.The rest mice in diabetes group were divided into two groups,diabetes control group,pro3 (GIP) group.Pro3 (GIP) group was given drug pro3 (GIP).The bloodglucose and glucose tolerance were measured.After treatment for 6 weeks,all mice were sacrificed and fatty tissues were collected.Results After 6 weeks,the blood glucose of the pro3 (GIP) group was obviously lower than diabetes control group (t=8.43,P＜0.01),and insulin levers in 0,30,60 and 120 min were obviously lower than diabetes control group (t =3.90,2.60,6.88 and 3.33,P＜0.05).There was significant difference between pro3 (GIP) group and diabetes control group about inflammatory cells.Moreover,leptin in pro3 (GIP) group was obviously lower than in diabetes control group (t =5.04,P＜0.01),but triglyceride,cholesterol,and adiponectin had no significant difference between two groups.Conclusion Pro3 (GIP) can significantly reduce blood glucose,insulin level,leptin of diabetes mice,and attenuate the inflammatory cells infiltration in fatty issue.
