[Histologic evaluation of testis in men with azoospermia in light of hormonal determination].

The causes of azoospermia may be of varied nature and are often difficult to determine. Generally, there are two morphological-clinical types of azoospermia. The first is due to the occlusion of the outgoing seminal tracts.

[Detection and treatment of hyperprolactinemia in male infertility].

The role of prolactin in males has not been satisfactorily explained. It has been proved that hyperprolactinemia has a negative effect both on spermiogenesis and spermatogenesis. It is widely known that the secretion of the pituitary hormones is of a pulsating character and occurs in the diurnal rhythm.

[Usefulness of examining gonadotropin hormones and testosterone in men with abnormal semen].

The aim of the study was to estimate the usefulness of some hormonal investigations in cases of males with abnormalities in semen analysis in the diagnosis of the male factor in the infertile couple. 107 males with the abnormalities in spermiogram underwent the analysis of the blood serum hormonal levels. Estimated was the level of FSH, LH, prolactin and testosterone.

[Rapid preliminary diagnosis of anaerobic bacterial infections. I. Natural fluorescence of pus, purulent fluids and dressing under UV radiation].

For evaluation of usefulness of natural fluorescence of clinical materials in UV radiation as rapid diagnostic method of infections with anaerobes, 405 samples of pus, bloody-purulent fluids, blood, wound secretions, dressings and other materials were investigated. Occurrence of red-brick UV fluorescence of clinical materials was compared with results of culture aimed at isolation of non-sporeforming anaerobes from "B. melaninogenicus group (P.

Cartilaginous teratoma of the ovary.

A case of ovarian teratoma of unique differentiation in a woman of 35 years is reported. Within the histologic structure of the tumor there is predominated cartilaginous tissue with signs of nuclear atypia. The microscopic appearance of the tumor resembled structures seen in chondroblastoma embryonale or even chondrosarcoma.

[Histological, morphometric and topochemical analysis of placentas from pregnancies with EPH Gestosis (author's transl)].

The authors' studies have shown three pathological phenomena to be predominant in placentas of women with EPH gestosis: disappearance of acid mucosubstance from wall of spiral arteries, reduction of ATPase, 5-Nase, and aP activities on apical and basal surfaces of terminal villi, and numerical increase as well as de-differentiation of trophoblastic nodes. Vulnerability of vascular walls to the action of vasodepressive factors is aggravated, according to the authors, in cases of complicated gestosis in which aMPS levels in the muscular membranes of spiral arteries are inadequate.
