Abstract
A quantitative ultrastructural study of somatotropic cells was carried out in 21-day-old malnourished rats after maternal food restriction during the nursing period. Changes represented mainly by a reduced cytoplasmic mass and diminished secretory material were found. A decrease in growth hormone secretion of malnourished weanling rats is suggested.
摘要
在哺乳期对母鼠进行食物限制后，对21日龄营养不良大鼠的促生长细胞进行了定量超微结构研究。发现主要表现为细胞质质量减少和分泌物质减少的变化。提示营养不良的断奶大鼠生长激素分泌减少。
