Effect of induced hyperthermia on microscopic structure of some parenchymatous organs in albino rats

ABSTRACT

Forty adult albino rats of both sexes were used in this study [10 females and 30 males]. Thirty of them [5 females 7 25 males] were exposed to hyperthermia six hours daily for 10 days while the remaining animals were kept as control. Six rats per time were sacrificed after 2, 4, 6, 8 and 10 days from heat exposure. Microscopical examination of heart, lungs, liver kidneys, adrenals, pancreas, uteri, ovaries and testes were carried out in all animals. Pathological lesions were found in the lung, kidney, adrenal, liver, and testis in the form of varying degrees of congestion, haemorrhage, oedema, degeneration and arrested spermatogenesis. These pathological lesions became more marked with increasing the period of heat exposure
