[Investigation of metabolic paramagnetic centers in the blood of patients with prostate adenocarcinoma prior to and after the plastic orchectomy].

Paramagnetic centers in the blood of patients with prostate adenocarcinoma have been studied prior to and after plastic orchectomy by EPR. It has been shown that significant alterations in blood paramagnetic centers occur after the surgery. These alterations point to an improvement of antioxidant properties of the blood.

Activity and content of antioxidant enzymes in prostate tumors.

Aim: To investigate the antioxidant enzyme system in blood of men with benign hyperplasia of prostate (BHP) and with prostate adenocarcinoma (CaP).

Methods: The spectrophotometrical methods were applied to study content and activity changes of superoxide-dismutase (SOD), catalase (CAT), ceruloplasmin (Cp), tripeptide glutathione (GSH), glutathione-peroxidase (GSH-Px), and glutathione-reductase (GR). Lipid peroxidation was evaluated using thiobarbituric acid (TBA)-test.
