[Activity of selected enzymes in urine of workers from the repair brigades in chemical plants "Organika-Azot" in Jaworz].

In 45 repair service workers of a chemical plant producing pesticides the serum concentration of creatinine and uric acid as well as the concentration of proteins and the activity of alkaline phosphatase, a alanine and aspartate aminotransferases, lactic dehydrogenase, and N-acetyl-beta- glucosaminidase in urine were determined. As compared to 31 healthy controls, the serum creatinine concentration was significantly higher (in any case the creatinine and uric acid concentration did not exceed the upper normal limit), the urine lactic dehydrogenase and N-acetyl-beta- glucosaminidase activity, factored by creatinine, was significantly elevated. The results of the examinations point to a discrete lesion of the kidneys.
