[Role of surgical treatments in patients with fibrocavernous pulmonary tuberculosis].

Three hundred and seventy patients operated on at the Institute Surgical Clinic underwent 638 surgical interventions: 356 and 282 in Groups 1 and 2 patients, respectively. Intraoperative complications occurred in 24 (3.8%) cases, in 6.

[Artificial pneumothorax in the surgical treatment of progressing bilateral destructive lung tuberculosis].

23 patients with fibrous-cavernous pulmonary tuberculosis received surgical treatment at the Novosibirsk Research Tuberculosis Treatment Institute. In the contralateral lung all the patients had recent infiltrative lesions with destruction. M.

Is the human trophoblast in vitro an adaptive tissue for immunological influences?

The role of the extra-embryonic organs (e.g. placenta) in the feto-maternal immunological interactions is not clear.

[Experimental inflammation of placenta in sheep].

The sheep desmochorionic placenta has been studied at aseptic inflammation produced by suturing it together with the uterus. The inflammatory process is evident from a decreased intensity of leucocytic phase and trophoblast participation in macrophagal phase; cytotrophoblastic elements and diplocariocytes transform into symplastic structures which seem to accomplish dendritic lysis and resorption. The foreign body incapsulation is performed with the maternal and fetal connective tissue participation.

[Study of a trophoblast cell culture in vitro].

The authors obtained trophoblast culture from an early chorion of human embryo. Trophoblastic cells of the main 4 types described were: giant cells, with processes, fibro-blast-like, and round. All the cells were rich in RNA, glycoproteins, had a set of enzymes of the Krebs pentose cycle, but low activity of succinic dehydrogenase.

[Changes in the human fetal membranes in late pregnancy toxicoses].

Changes of a destructive and adaptational character have been revealed in the extraplacental coats in late toxicoses of pregnant women by histological, histochemical and spectrophotometrical methods. The intesity of the apotomical way of the glucose oxidation decreased in the aminiotic epithelium. While the activity of enzymes converting the lipid decomposition products into glycolysis increased.

[Human placental morphology as an index of features of maternal-fetal relationships].

Principle possibilities of the complex evaluation of the mother-fetus exchange were studied by means of morphological investigations of the human placenta in normality, in vesicular mole, late toxicoses, hemolytic disease of newborns and malformations of the fetus. The investigation of the ratio of the villi of different size, deposition of fibrinoid on their surface, the change of the amount of cytotrophoblastic elements, cells of Kaschenko-Hofbauer and the polymerity of the basic substance are of diagnostic value. The authors propose the basal lamina of the placenta to be included into the scheme of the examination of placenta.
