Органопротекция предстательной железы в условиях варикозного расширения вен малого таза

Abstract

INTRODUCTION Chronic prostatitis is the most common urological disease. The morphological outcome of chronic inflammation is sclerosis, leading to the loss of functional active tissue. Venous congestion of the small pelvis can act as a trigger factor in the development of prostate sclerosis. Venotonics in combination with antioxidants may be considered for organoprotection of the prostate in pelvic varicose veins. PURPOSE to evaluate the protective effect of an antioxidant, venotonic and their combination on the process of formation of connective tissue in the prostate gland against the background of pelvic varicose veins in a chronic experiment. MATERIALS AND METHODS The experiment was carried out on a proven model of chronic venous congestion of the small pelvis and was carried out on 64 sexually mature rabbits weighing 2.6-3.2 kg. 5 groups have been identified. In the first group (n=15), an assessment of the effect of isolated antioxidant (resveratrol) was carried out. In the second group (n=15), an assessment of the effect of isolated venotonic (diosmin) was studied. In the third group (n=15), the effect of a combination of an antioxidant (resveratrol) and venotonic (diosmin) was evaluated. An aqueous solution of the preparations was injected daily for 180 days. In the fourth group (n=15), changes in the prostate were assessed against the background of venous congestion without exposure. In the fifth group (n=4), animals performed to provide data on normal anatomy. The animals were taken out of the experiment at 30, 90, 180 days. Prostate tissue was collected for histological examination and morphometry. In prostate samples, the concentration of hydroxyproline, a marker of connective tissue development, was investigated. RESULTS the isolated administration of resveratrol, as well as diosmin, does not sufficiently compensate for the changes in the hemodynamics of the small pelvis and the toxic effect of metabolic products. With morphometry on day 180, the proportion of glandular tissue in the gland / fibrosis ratio was significantly higher, and fibrosis was lower in Group 3 (79.36 / 9.08 (p<0.01) than in Group 1 (63.1 / 22.74) and Group 2 (65.52 / 21.0) .Quantitative study of hydroxyproline showed lower concentrations in the samples of Group 3 18.44 mg% (p<0.01), relative to Groups 1 and 2 (39.7 and 34.44 mg%) There were no statistically significant differences in the studied parameters between Groups 1 and 2. CONCLUSION the use of a combination of diosmin and resveratrol against the background of chronic venous hyperemia allowed, in the course of the presented experiment, to reduce the lesion volume and the growth of fibrous tissue in the prostate gland. The approach itself requires further study.
