Abstract :

Cloisonne kidney is an accidental finding of the kidneys observed in abattoir. The lesion caused by the thickening of the proximal and sometimes distal convoluted tubules basement membranes due to iron pigmentation is so far reported in goats, sheep and horses. Renal cortex is brown but the condition does not involve the medulla. The lesion brings about no impairment of the renal normal function and affected animals are clinically normal. Although the exact cause of this condition remains unknown but intravascular hemolysis is considered to have a role. The following study was undertaken to determine sheep cloisonne kidney frequency rate in Tabriz and Rasht abattoir. A number of 10000 sheep carcasses in Rasht slaughterhouse and 8600 carcasses in Tabriz slaughterhouse were randomly examined and tissue samples were stained with H&E. Only eleven cases were diagnosed with the cloisonne kidney lesion. Thus the frequency rate of the lesion was estimated at 0.059% in sheep of these cities.
