Abstract:
Objective To discuss the effects of abnormal nutritional supply during pregnancy on the adult insulin and leptin resistance in rats.Methods We established the pregnant rat models given either low protein or high nutrition diet,and normal diet group served as control.There were 12 pregnant rats in each group.After vaginal delivery,the pups birth weight were measured.The randomly selected small for gestational age(SGA)from low protein diet group,large for gestational age(LGA)pups from high nutrition diet group and normal birth weight pups from control group were studied at both 4 weeks and 12 weeks after being born.Each group contained 36 rats.The insulin and leptin level were measured by the method of ELISA,and insulin sensitive index were calculated respectively.Results The pups of mothers served with low protein showed obviously lower birth weight than those mothers with normal diet(P0.05),while the weight of fat around kidney,the ratio of fat and body weight(FW/BW)were(0.36?0.14)g,6.5?0.3,which were higher than those of control (0.19?0.13)g,3.4+O.3(P
