Abstract

This study was conducted to determine the effect of prolonged daily administration of aspirin on the microscopic structure of the goat kidney. Twelve apparently healthy, sexually mature, estrus-synchronized female goats were assigned randomly into four treatments and given aspirin (T1=0 g, T2 =10 g, T3 =20 g, T4 =30 g) once a day for 60 days. Tissues from cranial, middle and caudal portions of right or left kidney were processed routinely, stained with hematoxylin and eosin, alcian blue pH 2.5 and Jones method for kidney (JMK) (Luna, 1968) and observed under the light microscope. The capsule thickness, diameter of renal corpuscle and glomerulus, and distance between the most superficial corpuscles and the renal capsule were measured (μ); and the mean values +/- standard error of means of numerical data were computed. Results indicated that the kidneys of 0 g and 10 g ASA-treated goats presented a typical architecture. Those of the 20 g and 30 g ASA-treated goats showed morphological alterations such as a wavy renal capsule, consolidated renal tissue, contracted renal corpuscle, fused glomerular lobules and obliterated glomerular space and tubules, which suggest shrinkage of renal tissue. Another alteration, the hypercellular cortical and medullary tissues may indicate a hypersensitive or inflammatory reaction. The findings suggest that aspirin given for 60 days at double or triple the prescribed lOg dose, substantially altered the structure of renal tissue but was not toxic enough to produce severe pathological lesions in the goat kidney.
