Abstract

Nitric oxide (NO) level in serum and renal tissue has been examined in 15 male Wistar rats, body weight 200-250 g, 7 days after unilateral nephrectomy. All rats were ether-anaesthetized and the kidneys were removed by dorsolateral approach. NO concentration in serum and renal tissue was determined by classic colorimetric Griess reaction. Conversion of NO(3)(2-) into NO(2)(2-) was done with elementary zinc. Results have shown that NO concentration in renal tissue is statistically higher in rats 7 days after unilateral nephrectomy then in control renal tissue before compensatory kidney growth (p<0,02). There is no difference between NO concentration in serum before unilateral nephrectomy and 7 days after nephrectomy. These findings suggest that NO may play an important role in mediating the hemodynamic changes associated with reduced renal mass.
