title: The level of ochratoxin a in patients after nephrectomy.
abstract: Ochratoxin A (OTA) was analyzed in human serum and kidney samples, collected in Poland in the Pomeranian region from March to September 2005. OTA was determined using reversed phase liquid chromatography with fluorescence detection. The collected samples were from patients after nephrectomy (9 from men and 11 from women) and control serum samples from people without kidney diseases (3 and 3, respectively). The mean concentration OTA in serum of the healthy group was 0.37 ng/ml in both men and women. In patients subjected to nephrectomy it reached 1.06 ng/ml in men and 0.94 ng/ml in women, the mean content of ochratoxin A in kidneys was 0.23 ng/g and 0.20 ng/g, respectively. The highest concentration of OTA in serum among the patients subjected to nephrectomy was 3.77 ng/ml in men and 2.27 ng/ml in women while in kidneys 0.45 ng/g and 0.39 ng/g, respectively.
