| 摘 要： | 目的观察吡啶－２，６（１Ｈ，３Ｈ）二酮生物碱（ＳＨ１）对ＡＤＰ、ＡＡ、Ｃｏｌｌａｇｅｎ诱导的兔血小板聚集的影响。方法用比浊法测定了ＳＨ１体外对兔血小板聚集的影响。结果ＳＨ１对３种诱导剂的最大抑制率分别为６２．１６％、４５．２５％、５３．６７％。大剂量组明显加快ＡＤＰ诱导的兔血小板聚集后的解聚速度。ＳＨ１显著延长Ｃｏｌａｇｅｎ的诱导起聚时间。结论ＳＨ１０．８～４．０ｍｍｏｌＬ－１范围内明显抑制ＡＡ、ＡＤＰ、Ｃｏｌａ－ｇｅｎ诱导的兔血小板聚集。其抑制作用有明显的量效关系。其机制待进一步研究。

Inhibitory effect of pyridine 2, 6(1H,3H) dione alkaloids on rabbit platelet aggregation induced by ADP,AA and Collagen |
| |
| Abstract: | AIM To investigate the effect of pyridine 2,6(1H,3H) dione alkaloids SH1 (from speranskia tuberculata) on rabbit platelet aggregation induced by ADP, AA and Collagen. METHODS Platelets aggregation induced by arachidonic acid (AA) or adenosine diphosphate (ADP) or Collagen were studied by turbidimetry and radioimmunoassay in rabbits blood, in vitro. RESULTS SH1 08, 10, 20 and 40 mmol·L-1 inhibited platelet aggregation. The inhibition by SH1 was dose dependent: 234%￣622%(ADP induced), 116%￣453%(AA incuced), 18%￣537%(COL induced), in vitro. CONCLUSION SH1 and Aspirin could inhibit rabbits platelet aggregation induced by ADP, AA and COL. |
