The results of the experimentshowed that after 10 minutes of acute ischemia, the function of myocardial messangers ot phosphoinositide in-creased, and the levels of phosphatidylinositol-4, 5-biphosphate ( PIP2 ) and inositol-1, 4, 5-trisphosphate(IP3 ) were obviously higher than those of the non-ischemia control groups ( P < 0. 01 , n = 7) . CSMI (2 glkgbody weight) could markediy inhibit myocardial PIP2 and IP3, whose levels became lower than those of theischemia control groups ( P < 0 . 01 , n = 7 ) .展开更多

The results showed that : (1) The differ-ence was not obvious in the morbidity of complications between the two groups, but the mortality (3.6% ) ofthe trial group was significantly lower tlian that ( 30. 8% ) of the control group ( P < 0. 05 ) ; ( 2 ) Hematocritwas clearly decreased from 46. 1 5. 2% to 33. 2 3. 9% in the trial one ( P < 0. 05) , but platelet andhemoglobin showed no statistical signiticance.
