Abstract

The present study was undertaken to elucidate the effect of Serotonin and Norepinephrine on Aldehyde Oxidase activity in rabbit liver, in vitro. The results were as follows; 1. Aldehyde Oxidase was measured optimum substrate concentration at $5{\times}10^{-4}M$ and incubation time for 10 minutes. 2. Aldehyde Oxidase were inhibited by Serotonin and Norepinephrine. 3. It was observed that relationship between biogenic amines and substrate were competitive inhibition on Aldehyde Oxidase.

실험동물(實驗動物)의 간장(肝臟)을 적출(摘出)하여 aldehyde oxidase를 정제(精製)하고, 이 정제효소(精製酵素)에 대(對)하여 생체활성(生體活性) amine인 Serotonin과 Norepinephrine이 이 효소에 미치는 영향(影響)을 관찰한 성적은 다음과 같다. 1. Aldehyde oxidase측정(測定)에 있어서 기질(基質)인 N-methylnicotinamide의 최적농도(最適濃度)는 $5{\times}10^{-4}M$이었으며 반응시간(反應時間)은 10분(分)정도이었다. 2. Serotonin과 Norepinephrine은 본(本) 효소활성(酵素活性)에 억제적으로 작용(作用)하였다. 3. Serotonin과 Norepinephrine이 본(本) 효소활성(酵素活性)을 억제시키는 것은 각각(各各) 경쟁적인 억제작용이었다.
