Current study aimed to investigate the effect of piroxicam on some hematological
and biochemcal parameters. For this reason forty males mature Sprage Dawlley rats
were divided into four equal groups. control group administrated distilled water
(G1), and three groups administrated (20mg/kg,30mg/kg,40mg/kg) body weight of
piroxicam for 45 days. The results showed significant decrease (P<0.05) in
hemoglobin (Hb) and packed ceq volume (PCV) in groups treated with
(30,40)mg/kg of piroxicam, while the treated groups produced significant increease
(P<0.05) in the total white blood cell count (WBC). On the serum biochemical
porameters, Piroxicam caused increase in the level of liver enzyme amunotans ferase
(ALT) and aspartate amintou (AST) Also recorded significant changes in the level
of kidney function (creatinine, blood urea, uric acid). Histological studies appeared
piroxicam caused more severe damage to the liver included depletion of
glycoprotein, nearosis congestion, fatty change and inflammatory cell infiltration,
kidney section appeared shrink of glomeruli, dilated renal tubules and necrosis were
noticed in the renal tubules. Also the testes section appeared no effect in all the
treatment groups except in the group which treated with piroxicam _40mg/kg)
which showed thickening of somniferous tubules, shrink of leyding cells and
necrosis of germ cells. This study shows that the toxic effect of piroxicam depends
on time and conceutration of dose administration.
