Deoxyribonuclease activity in biological fluids of healthy donors and cancer patients.
Integral activity of neutral deoxyribonucleases in the plasma and urine or donors, patients with benign prostatic hyperplasia, and patients with stomach and prostatic cancer was studied by IFA based on hydrolysis of DNA fragment modified with haptene molecules. In donors plasma deoxyribonuclease activity was 0.16+/-0.04, urinary activity 1.49+/-1.41 act. U/ml. In patients with benign prostatic hyperplasia and malignant tumors the integral activity of blood deoxyribonucleases was significantly below the normal, and in tumors it did not correlate with tumor size and disease stage. A significant correlation between blood and urinary deoxyribonuclease activities was detected.
