Effects of adrenalectomy, adrenal regeneration, and renal irradiation on blood pressure. [X rays; rats]
Adrenalectomized, adrenal-enucleated and adrenal-intact rats were sham-irradiated or received an x-ray dose of 1100 rad bilaterally to temporarily exteriorized kidneys. Systolic blood pressures were measured at 10, 25, 40, 60, and 80 days after irradiation. At 100 days after irradiation the rats were sacrificed for gross pathologic examination and renal histopathologic studies of the kidneys. Adrenalectomy alone caused a significant drop in blood pressure which persisted throughout the experiment; adrenal regeneration in adrenal-enucleated rats or in those adrenalectomized rats in which adrenal tissue regenerated caused a significant increase in systolic blood pressure after 80 days postirradiation. Irradiation of adrenal-intact, adrenal-regenerating, or adrenalectomized rats did not cause significant elevation of blood pressure in comparison with that of the corresponding nonirradiated controls. Rats showing subtle renal histological changes usually showed somewhat higher blood pressures than rats showing no renal histological changes; a few rats which became severely hypertensive showed considerable histopathological changes in kidneys and other organs.
