The present experiments were performed to study the effects of a single high intravenous dose of Liquoid (10 mg/kg body weight) upon platelets, coagulation activities and hematocrit in blue foxes, and their correlation with the survival time. Both “short-living” (< 9 h) and “long-living” (24 h or more) blue foxes showed a marked consumption of coagulation factors, initial fall in fibrinogen, positive ethanol gel test and a gradual decrease in platelet counts. In addition “short-living” animals developed a marked rise in hematocrit, reflecting a considerable increase in vascular permeability. We conclude that activation of plasma proteases has as one of its effects increased permeability in microvasculatory vessels and that this may play a central role for the course and outcome of Liquoid-induced disseminated intravascular coagulation.
进行本实验是为了研究静脉注射单次高剂量的羟乙基淀粉(10毫克/千克体重)对蓝狐血小板、凝血活性和血细胞比容的影响,以及它们与存活时间的相关性。“存活时间短”(<9小时)和“存活时间长”(24小时或更长时间)的蓝狐均表现出凝血因子的显著消耗、纤维蛋白原初始下降、乙醇凝胶试验呈阳性以及血小板计数逐渐减少。此外,“存活时间短”的动物血细胞比容显著升高,反映出血管通透性大幅增加。我们得出结论,血浆蛋白酶的激活有一个作用是增加微血管的通透性,这可能在羟乙基淀粉诱导的弥散性血管内凝血的病程和结果中起核心作用。
