Mitochondria cristae and membrane in a great measure were anastomosis or vacuolization.Conclusion: All these results suggest that effects of H2S on papillary muscles are due to an increase in potassium efflux through opening the KATP channels at the early phase of ischemia, and acceleration in potassium reuptake through improving the Na+-K+-ATPase at the late phase of ischemia. Endogenous H2S may act as important regulator in electrophysiological characters in ischemic papillary muscles.

Every group rats were divided into two parts with the same rats. At last the rats were redivided ,then them were killed and their brains were excluded after one hour.4 hours or one week.Results PO2 and cerebral blood flow of E-selectin 2mg/kg group were higher than that of saline and lower than that of l0mg/kggroup(p.01).The volume of cerebral infarct and blood speed of E-selectin 2mg/kg group was smaller than that of saline and larger than that of l0mg/kg group(p.01).At the same time PCh.speeds.flows and the volume of infarct were related with the time (p.01).Conclusion E-selectin can effectively increase PC2 and rCBF after ischemia and reperfusion .reducing infarct volumes and speeds of blood at the same time . Artificial synthetic E-selectin can effectively reduce the reperfusion injury following cerebral ischemia.
