Abstract

Aim. To establish the structural changes in the prostate of reproductive experimental animals in conditions of long immunosuppression.

Materials and methods. Sixty white rats of reproductive age were studied. The state of immunosuppression was modeled with intramuscular introduction of cyclophosphamide in the dose of 1.5 mg/kg of the body mass during 10 days. Linear sizes and volume of the organ were determined. At the microscopic level, height and width of epithelial cells, their volume as well as large and small diameters and cell nuclei volumes were determined.

Results. In response to long immunosuppressive impact, organometric indices of the prostate both in the early (on days 7, 15) and late (on day 30) observation periods decreased owing to indirect cytotoxic impact of cyclophosphamide on the glandular and stromal components of the organ.

Conclusions. The decreased values of linear-volumetric micromorphometric indices within the same observation periods confirm the dynamics of organometric parameters of the gland and prove intensive response of the organ at micro-and-submicroscopic level.
