정상 흰 마우스의 동적미세구조 추이와 가령효과 : 갑상선에 관하여

Abstract

A sum of sixty-eight normal albino mice (29 of male and 39 of female). age ranging from 4-day old to more than 50-week old. has been investigated. The experimental animals were classified into 14 final groups. were principally for detection of the influence due to age by means of semiquantitative micro-radioautographic application. Each of the animals was sacrificed in deifnite daytime. 120 minutes after the intraperitoneal administration of a single dose of 0.8 micro-Ci per gram for the animal'sbody weight. and the neccessay histological steps with stripping film radioautographical procedures without pre-staining thereafter. then prepared a permanent slide with nuclear single stain with hematoxylin. The radioautograms were analyzed. 1. The trend of the labelings, in general. was shown somewhat decline fashion with the age. was suggested as a probability of age-influence. 2. The range of labeling appears to be influenced by various endo-exogenic factors. especially in female with productivity as more as the others. 3. A more detailed contribution. if any. are desirable with real in near future.
