The Influence of the Function of Adrenal Cortex upon the Duration of Intravenous Anesthesia Part 2. The relationship between Thorn-test value and anesthetic duration in rabbits with normal adrenal cortex

1) The value of eosinophile leukocytes of normal rabbits estimated by SAKURADA's modification with wet eosinperoxydase was 30-110. It was constant in the same rabbit. 2) For the Thorn-test in rabbits, 10 mg of ACTH was injected intravenously and after 5 hours the decreasing ratio of eosinophile leukocytes was estimated. The greater part was 50-65%. Accordingly, those more than 50% are regarded as the normal function of adrenal cortex and those less than 50% are counted as hypofunction. 3) Between the Thosn-test value and the duration of anesthesia, there is a logarithmic curve relation: the less the value is, the longer the duration of anesthesia stands. 4) The weight of adrenalin is 700±25mg i. e. it applies to nearly 0.03-0.04% of body weight. There is no difference between left and right side.
