Methods The dynamic calcium concentration in single guinea-pig ventricular myocyte was measured by laser scanning confocal microscope.

应用激光扫描共聚焦显微技术动态测量单个豚鼠心室肌细胞胞浆钙的浓度。

Results showed that L-THP possessed negative inotropic and negative chronotropic action, lowed left ventricular pressure and it's infinitesimal calculus, decreased heart output in per min., shorten 〓 and 〓 of action potential of ventricular papillary muscle of guinea pig and even the plate-phase of action potential disappeared in larger dose group , but prolonged 〓. we studied transmembrane transportation of 〓 after administering L-THP , L-THP not only depressed uptake and increased release of Ca 2+ in normal myocardium, but also it showed stronger inhibition in cell injured by ISO, and fully eliminated the effect of ISO increasing uptake and decreasing release of 〓. By detecting the 〓 content of ventricular single myocyte using fluorescent probe Fluo-3/AM, results correspond to that done above, L-THP decreased 〓 content inside of cell significantly. Using whole-cell mode, we observed the effect of L-THP on Ica in ventricular single cell, it was found that L-THP decreased Ica, the effect increased with increasing it's dose, and had voltage, frequency-dependency. Dose highly corelated to effect, corelative constant is 0.87. When washing cell with normal tyre's solution, Ica could recover, which proved the blocked action of L-THP on calcium channel once again. Meanwhile, L-THP reduced production of MDA in heart injured by ISO in dose-dependent manner, improved content of GSH-Px, in case tissue or cell free from free radical damage.

结果显示,该药物具有负性肌力和负性频率作用,降低左室压及其微分,终使每分心输出量减少;缩短豚鼠心室乳头肌动作电位时程的〓和APD〓,大剂量使动作电位平台消失,〓延长;同位素示踪法研究证实L-THP抑制〓摄取,促进〓释放,降低细胞内的〓含量;单通道水平的研究证实,L-THP减少豚鼠心室肌单细胞内向钙电流,且具有剂量,电压,频率依赖性,其作用易于洗脱,药物剂量与Ica也具有高度相关性(相关系数r为-0.87);L-THP还可抑制ISO损伤心肌组织所致的丙二醛含量增加,增加谷胱甘肽过氧化物酶的量,使组织细胞免受损伤。L-THP阻断L-型〓通道,抑制〓的摄取,促进〓的释放,降低细胞内〓含量L-THP作用的离子基础。

Objective To explore the significa nc es of myocyte apoptosis in elderly patients with acute myocardial infarction.

目的 探讨细胞凋亡在老年急性心肌梗死时心肌细胞中的意义。

Results (1)The permillage of myocyte apoptosis in infarct area in elder patients with sudden death caused by AMI was significantly higher than that in control group(663.00‰±117.12‰ vs 34.30‰±20.68‰,P<0 .01).However the permillage of myocyte apoptosis in 1-vessel,2-vessel,and 3 - vessel disease were 514.28±165.12‰,564.38‰±102.33‰ and 668.25‰±127. 19‰,respectiverly,significantly higher as compared to control group(All P< 0.01).But no significance was found among the three groups.(2)The size of DNA f ragment about 180~200 bp was found only in those patients with two and three ve ssels involoved.(3)The electron microscope showed the characteristics of myocyte apoptosis episodes,the others showed the characteristics of necrosis.
