Acute renal failure (ARF) was produced by the single intraperitoneal injection of 3 mg/kg mercuric chloride (HgCl2) in male Wistar rats. Immediately after, and in the 1st, 3rd, 6th, 24th and 48th hour after HgCl2 administration the following variables were monitored: plasma renin concentration (PRC), renal renin concentration (RRC) blood-urea nitrogen (BUN), plasma sodium (PNa), plasma creatinine (PCr) concentrations and haematocrit (Ht). Haematocrit and PNa increased during the first hour and returned to the control value in the 3rd hour. Thereafter, their level remained unchanged. Plasma renin concentration increased threefold during the first six hours after the HgCl2 injection, however, by the 48th hour it returned to the control value. In the first 24 hours of ARF, RRC remained unchanged. However, by the 48th hour its level increased four times the control value. After mercury injection BUN and PCr increased progressively. We were not able to establish any significant correlation between the changes of PRC and BUN. A gradual increase of RRC was observed in the course of ARF.
