ABSTRACT

Objective To investigate effects of limbs ischemic postconditioning induced remote postconditioning (RPostC) on mitochondria structure and function after focal cerebral ischemic reperfusion(I/R) injury in diabetic rats. Methods The diabetic rats models were induced by injecting streptozotocin into abdominal cavity. I/R rats models were made by MCAO with thread. Forty male SD rats models were assigned to 4 groups: control group; sham operation group; I/R group;RPostC group ( n=10 ) . 6 h after the reperfusion, the brains were obtained for HE staining. The mitchondria were isolated and content of MDA,the activities of SOD,Na+/K+-ATPase,Ca2+-ATPase and GSH-Px were tested. Morphological changes of neuronal mitochondria were observed by electronic microscope. Results In the I/R group,the content of mitchondria MDA[(4.99?1.25) nmol/mgprot]were markedly increased (P
