Premature ageing of pituitary of irradiated ICRC mice

Abstract

The secretory cycle of pituitary cells has been studied in ICRC young adult mice receiving whole body X-irradiation with the fractionated dose of 150R/wk for 4 wk. Sequential autopsies were performed at 80, 100 and 120 days after the first dose of irradiation. From the tinctorial affinity of the cells it was difficult to classify the pituitary cells under light microscopy. The secretory cytology was therefore studied under electron microscope. It was observed that the growth hormone secreting cells (GH) having well developed Golgi and endoplasmic reticulum (ER) were predominantly spread over the lobe at all three periods. However, the clumping of secretory granules and lytic bodies were seen only in the 120 day group. Few secretary granules, ill-defined Golgi, vesicular cytoplasm and lipid bodies were sequential changes that took place in the follicle-stimulating hormone cells (FSH). Along with these changes in the pituitary, atresia of the ovaries or proliferation of Leydig cells was observed. 3 figures, 16 refs.
