Objective To study the effect of liquid extracts from leaves of Canarium pimela Leenh on myo-cardial ischemia-reperfusion injury in rats. Methods The langendorff isolated perfused heart system was applied in this study. Ligating of the left descending anterior for 35 min,followed with 100 min or 50 min reperfusing to set up the cardiac ischemia-reperfusion injury model (I/R). After perfusing the effective pharmacological extracts of leaves of Canarium pimela Leenh(CPL)to the isolated heart,we monitored the cardiac parameters of left ventricu-lar systolic pressure(LVSP),left ventricular end-diastolic pressure(LVEDP)and left ventricular maximal rise/fall of left ventricular pressure(±dp/dtmax)in the following assays with or without 10 min CPL pretreatment. 1. the cardiac parameters,2. the cardiac parameters in 35 min ischemia,followed with 10 min or 50 min reperfusion,3. the incidence of ventricular fibrillation or ventricular tachycardia after 10 min reperfusion,4. the activity of creatine kinase(CK)and lactate dehydrogenase(LDH)in the coronary effluent after 10 min reperfusion,5. pathological analysis in the I/R,CPL and VER group after reperfusion. Results CPL pretreatment improved functions of normal left heart. Furthermore,it significantly reduced LVEDP and +dp/dtmax,the incidence of ventricular fibrillation or ventricular tachycardia,as well as the activities of CK and LDH in coronary effluent induced by ischemia-reperfusion compared with the I/R model. Moreover,CPL pretreatment markedly alleivated the pathological changes of ischemia-reperfusion. Conclusions The liquid extracts of leaves of Canarium pimela Leenh can effectively relieve the myocardial ischemia-reperfusion injury in rats.

Objective To probe into the change regulation before and after treatment every snake bite patients for the routine blood test and serum hs‐CRP .Methods The study objects were selected in the hospitalized patients for clear diagnosis belong to what kind of snakes in the past two years .The indexes of routine blood test and serum hs‐CRP were determined before and after treatment various periods in these patients .The test results were made to statistical analysis according to kind of snakes ,periods and disease condition .Results WBC was obvious .rise before treatment only the viper snake bite patients .WBC was all significant .rise after treatment first day and second day for 5 kinds snake bite patients (P<0 .01) .This index had all reduced trend after treatment fourth day but determined value was still high in contrast to the normal reference scope .RBC and HGB all were normal level and had not obvious change before and after treatment for 5 kinds snake bite patients .PLT was reduced before treatment for the trime‐resurus gramineus bite patients ,before and after treatment for the viper snake bite patients (P<0 .05) .The hs‐CRP content was higher before treatment for the viper snake bite patients and was highest after treatment for the cobra snake bite patients ,the inter‐comparison had significant difference (P<0 .05) .Conclusion 5 kinds snake bite patients before and after treatment not basely ane‐mia symptom .But most of the patients appear the inflammatory response .PLT decrease is more serious for the trimeresurus grami‐neus bite patients ,and for the viper snake bite patients especially .
