Blood samples and the two adrenals were collected from 96 male calves at slaughtering in Mosul
Slaughter-house through the period from 2/1/2011 – 1/3/2011 at ages ranged from 1-1.5 years .
Cortisol level has been estimated in blood serum by using enzyme linked immuno-sorbant assay
(ELISA) . Gross and histopathological examination was performed on adrenal sample . Lesions found
were identified , classified their percentage of occurence within the total collected samples
percentages , unilateral-bilateral occurance and also correlations between those lesions and cortisol
level have been determined . The results demonstrated presence of multiple lesions at 68.43% of total
adrenal samples , those were represented by congenital deformities included medullary tissue islets
within cortex at 4.46% of the total examined samples, loubulated adrenal glands at 1.98%, accessory
cortical tissue with capsule 4.95%, and accessory cortical tissue within medulla at 4.95% , also
disturbance of cellular metabolism where noticed represented by cortical vacular degeneration ,

chromaffine cell vacular degeneration , cortical cellular cloudy swelling , chromaffine cell cloudy swelling and chromaffine cell coagulative necrosis at ratios 28.71% , 15.84% , 1.49% , 1.98% and 4.95% respectively . Disturbances of cellular adaptation included diffuse cortical hyperplasia , nodular cortical hyperplasia , diffuse medullary hyperplasia at ratios 11.88% , 2.97% and 3.47% respectively . Circulatory disturbances appeared as congestion and edema at 26.73% , adrenal hemorrhage at 1.98% and vascular wall thickening at 7.43% in total examined samples . Acute adrenalitis 2.97% , focal lymphocytic corticoadrenalitis 11.88% , capsular septal thickening at 32.67% represented the lesions of inflammation and repair in total examined samples . The results did not show an obvious correlation between blood serum cortisol level elevation and occurrence of adrenal lesions in calves , except accessory corticalm tissue within capsule , accessory cortical tissue within medulla , accessory medullary tissue within cortex , diffuse cortical hyperplasia and vascular thickening where the most effective lesions on cortisol level in calves blood serum .
