摘要: 目的: 研究山茱萸环烯醚萜苷(CIG)对血小板聚集和出血时间的影响。方法: 应用比浊法测定家兔(体外实验)及血瘀模型大鼠(体内实验)的血小板聚集率;断尾法观察大鼠出血时间。采用肾上腺素加冰水刺激法制备血瘀大鼠模型。结果: 在体外实验中,CIG (0.75~3 mg/mL)能明显抑制二磷酸腺苷(ADP)或花生四烯酸(AA)诱导的家兔血小板聚集(P<0.05,P<0.01),对血小板活化因子(PAF)诱导的血小板聚集无显著影响,但更大剂量(6~12 mg/mL)能抑制PAF诱导的血小板聚集(P<0.01)。在体内实验中,CIG大剂量(180 mg/kg)灌胃给药能显著抑制ADP诱导的血瘀模型大鼠血小板聚集(P<0.01),延长正常大鼠的出血时间(P<0.05)。结论: 山茱萸环烯醚萜苷具有抗血小板聚集作用,大剂量能够延长出血时间。

Abstract: AIM: To investigate the effects of cornel iridoid glycoside (CIG) on platelet aggregation and bleeding time.METHODS: Born's turbidimetry was used to measure platelet aggregation rate in rabbits (in vitro) and blood stasis model rats (in vivo). The tail-cutting method was applied to determine the bleeding time in rats. The blood stasis rat model was established by adrenalin and ice water stimulus method.RESULTS: In vitro study showed that CIG (0.75~3 mg/mL)significantly inhibited platelet aggregation induced by ADP or AA (P<0.05, P<0.01), and CIG (6~12 mg/mL)obviously inhibited platelet aggregation induced by PAF (P<0.01) in rabbits. In vivo study demonstrated that intragastric administration of CIG (180 mg/kg) markedly inhibited platelet aggregation induced by ADP in blood stasis model rats (P<0.01), and prolonged the bleeding time in normal rats (P<0.05).CONCLUSION: CIG has the effect of anti-platelet aggregation, and its high dose can prolong the bleeding time.
