Biochemical changes in rat urine and tissues treated with five consecutive daily doses of ochratoxin A (10 mg/kg body weight) were studied. Urine volume and urinary proteins were moderately raised during the first few days of ochratoxin treatment, and were then highly elevated towards the end of the investigation. Urinary muramidase excretion was significantly raised (p less than 0.01) 24 h after the first insult with the toxin. The urinary output of alkaline and acid phosphatases, lactate dehydrogenase (LDH) and glutamate dehydrogenase (GDH) were all elevated but very much later, during the course of injections with ochratoxin A. Kidney alkaline and acid phosphatases, LDH and GDH were correspondingly reduced 7 days from the beginning of ochratoxin A administration. Liver LDH activity was reduced while serum LDH was raised. Liver glycogen level was significantly (p less than 0.0001) increased. Experimental evidence was presented to show that the initial point of interaction of ochratoxin A with the rat renal system may be at the first portion of the proximal convoluted tubular cell region.

Gentamicin has been shown to induce renal tubular damage in man and laboratory animals and to result in elevated urinary excretion of some enzymes associated with specific cell regions in the kidney. In the present investigation, the possible protective effect of selenium against gentamicin-induced renal damage was tested by measuring the urinary excretion of some enzymes in the presence and absence of selenium. Our results show that a prior subcutaneous injection of selenium to rats for two days followed by a simultaneous S.C. injection of gentamicin and selenium resulted in a marked reduction in the excretion of such biochemical systems as the urine volume, urinary proteins, alkaline and acid phosphatases, beta-glucuronidase, muramidase, and glutamate dehydrogenase. Renal functional studies revealed that selenium-treated rats suffered less adverse effects compared to rats treated with gentamicin alone. Urinary acid phosphatase, beta-glucuronidase and muramidase, the three lysosomal enzymes tested, appeared to respond most readily to protection by selenium.

The renal effect of the daily administration of gentamicin to male albino rats (20 mg/kg body weight) for 6 consecutive days on some biochemical systems of the kidney was examined. Urine volume and urinary protein levels were found to be progressively raised following gentamicin. Urinary alkaline phosphatase, acid phosphatase, muramidase and glutamate dehydrogenase (GDH) activities were found to be markedly elevated. Acid phosphatase and GDH activities in urine were raised 24 h and 48 h, respectively, from the onset of gentamicin administration. The sequence in which some regions of the renal cells were involved in gentamicin nephrotoxicity was determined and the probable mechanism of interaction of gentamicin antibiotic with the renal tubular cells is proposed.
