[摘要]小鼠采用華法林鈉造模，用斷尾法和玻片法分別測定出血時(shí)間和止血時(shí)間，大鼠連續(xù)15 d給藥測定血漿復(fù)鈣時(shí)間、血漿黏度、血小板黏附率、血小板聚集率等血液指標(biāo)。 與空白組比較，模型組能延長（P<005）出血時(shí)間，與模型組相比陽性維生素K、淋濾浸染型水煎液和沉積型水煎液能顯著（P<001）縮短出血時(shí)間，陽性維生素K能顯著（P<001）縮短凝血時(shí)間，淋濾浸染型水煎液、沉積型水煎液和沉積型粉末可（P<005）縮短凝血時(shí)間。與空白組比較，淋濾浸染型水煎液低劑量、中劑量和粉末中劑量，以及沉積型水煎液高劑量和藥渣低劑量都可降低血漿黏度（P<005），淋濾浸染型粉末高劑量和沉積型水煎液低劑量能顯著降低（P<005）血漿黏度。與空白組比較，禹余糧淋濾浸染型水煎液高劑量組能顯著降低（P<005）血小板黏附率，沉積型水煎液高能顯著增加（P<005）血小板黏附率，淋濾浸染型水煎液高劑量、藥渣高劑量和淋濾浸染型粉末低劑量、藥渣低劑量能降低（P<005）血小板聚集率，沉積型水煎液高劑量、粉末高劑量能增加（P<005）血小板聚集率。礦物成分分析利用偏光顯微鏡及X射線衍射（Xray diffraction，XRD）法。 2種礦物成因禹余糧礦物組成均含針鐵礦、石英、高嶺石，沉積型尚含伊利石、鈉長石。研究結(jié)果表明沉積型成因的禹余糧止血作用較好，可能與針鐵礦、伊利石含量較高有關(guān)。

[Abstract]Models were established in mice with warfarin sodium method， and their bleeding time and hemostasis time were measured by tail cutting method and slide method respectively Rats were administered for 15 consecutive days to measure their recalcification time， plasma viscosity， platelet adhesion rate， platelet aggregation rate and other blood indexes As compared with the blank group， the bleeding time was prolonged in model groupn（P<005） As compared with the model group， the results showed that the positive vitamin K， the leaching type water decoction and the sediment type decoction could significantly shorten the bleeding time （P<001）； positive vitamin K significantly （P<001） shortened clotting time， and the leaching type water decoction， the sediment type water decoction and the sediment type powder could also shorten the clotting time （P<005） As compared with blank group， low dose， medium dose of leaching type water decoction， medium dose of powder， high dose of sediment type decoction and low dose of drug residues could reduce plasma viscosity （P<005）， and high dose of leaching powder and low dose of water decoction could significantly reduce （P<001） plasma viscosity As compared with blank group， Limonitum leaching type decoction high dose group could significantly reduce the platelet adhesion rate （P<005）， while sediment type water decoction could significantly increase the platelet adhesion rate （P<005）； the high dose of leaching type water decoction， high dose of drug residues， low dose of leaching type powder and low dose of drug residues could decrease the platelet aggregation rate （P<005）， while high dose of leaching type water decoction and high dose of the powder could increase the platelet aggregation rate （P<005） Analysis of mineral compositions was conducted by polarized light microscopy and Xray diffraction （XRD） The results of the both methods showed that Limonitum mineral compositions contained goethite， quartz， and kaolinite， and sedimentary type also contained illite and albite Sediment type of Limonitum showed better hemostatic effect， which may be related to the high content of goethite and illite.endprint
