Quantitative ultrastructural study of somatotropic cells in malnourished weanling rats.
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.
