本文报导离体狗血中外源性 ACTH 的消长情况,将正常狗新鲜血液与新配制的 ACTH 溶液混合液,使每0.5毫升血液含国产天津牌 ACTH4iu,于6～18℃下温培,随即在0分,15分和60分钟取一定的混合液按 Sayers 法测定 ACTH 活性。(将所得结果减去该狗血样本身所含的内源性 ACTH 量作为外源性 ACTH 活性数值)外源性 ACTH 一旦与新鲜狗血接触后其活性减少66.2%,但温培15分钟 This article reports the excretion of exogenous ACTH in isolated dog blood. The normal dog fresh blood is mixed with the freshly prepared ACTH solution so that every 0.5 ml of blood contains domestic Tianjin brand ACTH4iu. The temperature is raised at 6-18 ° C, 0, 15 and 60 minutes to determine a mixture of ACTH activity by Sayers method. (The result is subtracted from the amount of endogenous ACTH contained in the dog blood sample itself as exogenous ACTH activity values.) Exogenous ACTH decreases its activity by 66.2% once exposed to fresh dog blood but is incubated for 15 minutes
