Abstract EN

The study aimed to detect adrenal gland lesions and determine their ratios at sheep and calves slaughterhouse at age ranged from 1-2 years for 2 months from 1/1/ – 1/3/2011 , and comparing the results between the two species .

Adrenal glands were harvistered from 110 sheep to collect 220 samples and from 96 calves to form 192 samples, Gross and histopathological examination were performed .

The results demonstrated presence of lesions at 83.64% of samples at sheep and at 82.29% at calves , those lesions represented by presence of congenital deformities including medullary tissue islets within cortex, lobulated adrenal gland, accessory cortical tissue within capsule and accessory cortical tissue within medulla, at ratios 1.82%, 0.9%, 6.36% and 2.73% respectively in sheep and at ratios 4.46%, 1.98%, 4.95% and 4.95% respectively in calves, beside presence of cystic adrenal medulla in sheep at 0.45% of samples .

disturbances of cell metabolism also noticed represented by cortical vascular degeneration, chromaffin cell coagulative necrosis at retios 29.55%, 10.45% and 2.27% respectively in sheep and at retios 28.71%, 15.84%, and 4.95% respectively in calves with presence of cloudy swelling in adrenal cortical cell and chromaffin cells at 1.49% and 1.98% respectively at calves adrenal samples cellular adaptation disturbances also observed manifested by diffuse cortical hyperplasia, nodular cortical hyperplasia, diffuse medullary hyperplasia at 6.36%, 4.09%, 2.27% respectively at sheep samples and at 11.88%, 2.97% and 3.47% respectively at calves, circulatory disturbance congestion and edema at 37.73% and thickening of vascular walls at 6.36% of sheep samples, the same lesions appeared in calves at 26.73% and 7.43% respectively from total collected samples, those disturbances also include hemorrhage appeared at 1.98% of calves samples .

Two form of inflammation appeared included focal lymphocytic corticodrenalitis at 12.27% in sheep and at 11.88% in calves, otherwise acute corticoadrenalitis demonstrated at 2.97% of calves samples .

Repair pross manifested by fibrosis of capsule and thickening of fibrous septa appeared at 28.63% in sheep and at 32.67% in calves .

Detection of tumors just included pheochromocyoma at 1.82% and unclassified medullary tumor at 0.9% of ovine samples in contrast a benign myelipoma was recognized at bovine adrenal cortex at 0.49% of samples .It has been concluded that an obvious variation is demonstrated in types and ratios of lesions between sheep and calves with regard to similarities in total affection ratios .
