Summary. The effect of paracetamol, commonly used as analgesic drug, upon excretion of some enzymes, markers of kidney damage, was investigated. Patients with Balkan endemic nephropathy and glomerulonephritis, having kidney vulnerable to toxic drugs, were enrolled in the study. Timed urine specimens were collected: before drug administration, and in 3h periods for 24 h after an oral dose of 2 g of paracetamol.
Excretion of APN activity related to mmol creatinine before paracetamol treatment was significantly higher in patients with glomerulonephritis than in healthy persons from the city or village, and from BEN patients. Urinary excretion of  DPP IV and GGT  was significantly increased in patients with glomerulonephritis, BEN, and in clinically healthy inhabitants of the endemic villages compared to healthy adults from the city. After paracetamol administration urinary excretion of APN, DPP IV and GGT did not change significantly in any group studied.
This study has shown that urinary excretion of APN, DPP IV and GGT, as markers of kidney brush border damage, did not change after 2 g of paracetamol taken orally.
Key words: Paracetamol, Balkan endemic nephropathy, glomerulonephritis, aminopeptidase N, dipeptidylpeptidase IV, gamma-glutamyltranspeptidase

IZLUČIVANJE ENZIMA URINOM  NAKON  UZIMANJA PARACETAMOLA
KOD OSOBA SA BUBREŽNOM BOLEŠĆU

Ispitivan je efekat paracetamola, leka koji se koristi kao analgetik, na izlučivanje nekih enzima, markera oštećenja bubrega. U ovoj studiji obradjeni su bolesnici sa Balkanskom endemskom nefropatijom i glomerulonefritisom  čiji su bubrezi osetljivi na toksično dejstvo lekova. Sakupljani su sledeći uzorci urina: pre uzimanja leka, i u intervalima od 3 sata za period od 24 sata nakon oralnog uzimanja 2 grama paracetamola.
Aktivnost APN u urinu po mmol kreatinina, pre tretiranja paracetamolom je značajno veća u bolesnika sa glomerulonefritisom nego u zdravih osoba iz grada i seoskog područja, kao i obolelih od  BEN. Izlučivanje DPP IV i  GGT urinom prema mmol kreatinina značajno je povećano u bolesnika sa glomerulonefritisom, BEN i u klinički zdravih ispitanika iz endemskih sela u odnosu na zdrave osobe iz grada. Tretman paracetamolom ne daje nikakve značajne razlike u izlučivanju enzima APN, DPP IV i GGT kod ispitivanih grupa.
U ovoj studiji je ustanovljeno da nakon uzimanja 2 grama paracetamola ne dolazi do promena aktivnosti enzima APN, DPP IV i GGT, kao markera oštećenja četkastog pokrova bubrega.
