In this research, the activities of CWDE were measured by saccharifying according to the theory that red-brown amino compounds were produced when 3, 5-dinitro salicylic acid and aldehyde were heated together. And the testing conditions were made clear. The activity of Cx should be tested with optimal temperature of 50℃, optimal pH of 4.8, incubation time of 30 min, and optimal substrate of 0.6% CMC-Na. Due to the heat-libality, Cx should be sterilized more than 10 min. The testing conditions of the activity ofβ-G were almost the same with Cx except the substrate of 0.5% salicin and the sterilization time of more than 15 min.

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.
