Abstract

Female sheep were used to assay antihaemophilic (factor VIII enhancing) activity of arginine vasopressin, deamino-(D-arginine8)-vasopressin (DDAVP) and adrenaline. The time course of the response was biphasic, two surges of factor VIII being observed. DDAVP was found to be the most potent of the substances investigated. Its optimal dose was 1 microgram kg-1 body wt (i.v.). It is suggested that a similar procedure can be employed to search for new peptides with anti-haemophilic action.

摘要

使用雌性绵羊来测定精氨酸加压素、去氨基-(D-精氨酸8)-加压素(DDAVP)和肾上腺素的抗血友病(因子VIII增强)活性。反应的时间过程是双相的,观察到因子VIII有两个峰值。发现DDAVP是所研究物质中最有效的。其最佳剂量为1微克/千克体重(静脉注射)。建议可以采用类似的方法来寻找具有抗血友病作用的新肽。
