摘要
目的:观察姜炭对虚寒性出血证大鼠凝血5项指标和血栓素B2(TXB2)、6-酮-前列腺素F1α(6-keto-PGF1α)的影响。方法:将80只SD大鼠随机分为8组:空白组、模型组、姜炭组和姜炭加模型组高、中、低剂量组,每组10只。模型组和姜炭加模型组均以大黄水煎液ig造成虚寒模型,共10 d。从造模第6天开始,空白组和模型组ig生理盐水,姜炭组ig给与不同剂量的姜炭混悬液(10,20,40 g.kg-1),1次/d,连续5 d;模型组和姜炭组采用眼眶放血法造成出血模型。末次给药后1 h采血测定凝血5项:凝血酶时间(TT)、凝血酶原时间(PT)、活化部分凝血活酶时间(APTT)、纤维蛋白原(FIB)、D-二聚体(D-D)和血栓素B2(TXB2)和6-酮-前列腺素F1α(6-keto-PGF1α)。结果:姜炭高、中剂量组能显著缩短虚寒性出血证大鼠的TT(P<0.05),PT(P<0.05),APTT(P<0.05),提高FIB的含量(P<0.01)、减少D-D的含量(P<0.05),提高TXB2(P<0.01)而下调6-keto-PGF1α(P<0.01)的含量。结论:姜炭可能是通过影响大鼠凝血系统和调节TxB2,6-酮-前列腺素F1α含量来发挥止血、凝血作用。
Objective:To investigate the effects of Zingiber officinale carbo on coagulation function and thromboxane B2(TXB2),6-keta-prostaglandin F1α(6-keto-PGF1α) in asthenia cold and blood deficiency syndrome Rats.Method: Eighty SD rats were randomly divided into 8 groups: normal control,model,small,medium and large dose groups of Z.officinale carbo.The model of asthenia cold was made by oral administration of rhubarb for 10 days.After 6 days of model,the normal control group and the model group were ig given normal saline.Z.officinale carbo groups were given the Z.officinale carbo decoction at different doses(10,20,40 g · kg-1) daily for 5 days.Blood deficiency syndrome was made by the orbit blooding method.1 h after lasting administration,blood samples were collected to detect the serum levels of thrombin time(TT),prothrombin time(PT),activated thromboplastin time(APTT),fibrinogen(FIB),d-dimer(D-D) and TXB2/6-keto-PGF1α were observed.Result: Z.officinale carbo could effectively shorten TT(P&lt;0.05),PT(P&lt;0.05),APTT(P&lt;0.05),increase the contents of FIB(P&lt;0.01),and decrese the contents of D-D(P&lt;0.05),increase the level of TXB2(P&lt;0.01) and decrease the level of 6-keto-PGF1α(P&lt;0.01).Conclusion: The mechanism of Z.officinale carbo may affect the coagulation and the level of TXB2 and 6-keto-PGF1α.
