Abstract:
Objective To investigate the impact of experimental stress on serum glucose , insulin, glucagon, cortisol, and ep-inephrine in diabetic rats and its intervention with insulin and fluoxetine .Methods Type 2 diabetic rats model was induced by feeding with high sugar and high fat diet , and intraperitoneal injection of streptozotocin (STZ).The rats were divided into normal group , dia-betic control group , diabetic treated with insulin , and diabetic treated with fluoxetine .All the rats were exposed to multiple stressors (forced swimming, cold stimulation, rotation, restrain, and crowding) for 8 weeks.The rat blood sera collected from each group were analyzed with multiple parameters including glucose , insulin, glucagon, cortisol, and epinephrine at the 4th and 8th week.Results After experimental stress, the levels of glucose [(16.7 ±3.5)mmol/L vs (5.1 ±1.1)mmol/L, t =13.9, P <0.01], glucagon [(158.5 ±50.2)ng/L vs (120.8 ±38.7)ng/L, t =2.5, P <0.05], epinephrine [(203.8 ±48.6)pg/ml vs (158.7 ±42.6)pg/ml, t =2.9, P <0.01], cortisol [(21.3 ±4.8)ng/ml vs (18.2 ±3.8)ng/ml, t =2.1, P <0.05], and HOMA-IR (10.9 ±2.6 vs 3.3 ±0.8 , t =12.3 , P <0.01 ) of diabetic rats were significantly increased .The glucose level [ ( 9.7 ±2.1 ) mmol/L vs ( 16.7 ± 3.5)mmol/L, t =7.0, P <0.01] was significantly improved after treated with insulin .The levels of epinephrine [(158.8 ±37.5 ) pg/ml vs (203.8 ±48.6)pg/ml, t =3.0, P <0.01], and cortisol [(15.7 ±4.2)ng/ml vs (21.3 ±4.8)ng/ml, t =3.5, P <0.01 ] were significantly improved after treated with fluoxetine .Conclusions Experimental stress increased the levels of glucose , en-docrine hormone , and insulin resistance of diabetic rats .Treatment with insulin improved the glucose level and treatment of fluoxetine improved the endocrine hormone level .
