EFFECTOFALLITRIDIONPLATELETAGGREGATION,A PRELIMINARY STUDY 总被引:1,自引:0,他引:1
The present study is aimed at assessing theeffects of allitridi,a major component of garlic,on platelet aggregation and the activity of PGI_2-like substance in arterial tissue.Results indicatethat platelet aggregation is inhibited by allitridiand aspirin.The activity of PGI_2-like substanceis also inhibited by aspirin,but not by allitridi. 相似文献

本文观察了不同剂量的气血注射液(含人参、黄芪、当归)对29例冠心病患者血小板粘附、聚集功能及血浆 TXB_2(血栓素 B_2)、6-keto-PGF_(1α)(6-酮-前列腺素 F_(1α))含量的作用。结果说明气血注射液体内试验对血小板粘附功能有明显的抑制作用;对中医辨证属气虚血瘀的冠心病患者的血小板聚集有明显的抑制作用,而对辨证属阴虚血瘀或挟有痰湿者则有可能促进其血小板聚集的作用。初步说明了该药物的证效关系。气血注射液尚有使血浆 TXB_2含量明显下降、血浆6-keto-PGF_(1α)含量明显增加的作用。 相似文献

本研究采用单盲法,在同一患者自身前后对照气血注射液及葡萄糖液对心绞痛的疗效。结果说明心绞痛症状及心电图的疗效,气血注射液均十分明显优于葡萄糖液,并经次极量活动平板运动试验的客观验证,气血注射液确可提高冠心病患者运动耐受量,而葡萄糖液则无此作用,证明气血注射液治疗心绞痛的疗效是肯定的。该药并明显改善左心功能及心排量,改善血液的流变性及微循环,增加心肌营养血流量,对心肌细胞膜钠-钾 ATP 酶的活性有一定的抑制作用。 相似文献

Streptomycin showed negative inotropic effects on the isolated hearts (toad, rabbit, and guinea-pig). The contractions of isolated rabbit ileum and rat uterus were also in- hibited by streptomycin. In the experiments on perfused isolated rabbit ear, streptomycin had no effect on the outflow of perfusing fluid. The contractive responses of rabbit aorta strips to adrenaline was neither prevented nor abolished by streptomycin. Calcium ions antagonized the depressing effects of streptomycin on the isolated rat uterus, but did not influence the inhibitory effects of streptomycin on isolated hearts (toad, rabbit, and guinea-pig) and rabbit ileum. Our experiments showed that calcium ions only partly antagonized the pharmaco- logical action of streptomycin on certain isolated organs. 相似文献

人参——对红细胞中2、3-二磷酸甘油酸的影响 总被引:6,自引:0,他引:6
<正> 人参为中医临床常用的补气药,功能:大补元气,强心固脱,安神生津。关于人参的作用国内外学者进行了广泛的药理研究。文献报道,人参对中枢神经、周围神经、心血管、造血、消化、内分泌、物质代谢、泌尿生殖等系统都有作用,并能提高机体的适应性。独参汤及参附汤可治疗大失血或一切急慢性疾病引起的面色苍白、大汗肢冷、呼吸微弱等虚脱症。近年人参制剂如生脉散等治疗冠心病心绞痛、心肌梗塞等急证也取得了一定的疗效。1967年人们发现2、3—二磷酸甘油酸(简称2、3—DPG)可降 相似文献
