[On the histo- and morphogenesis of sclerosing pneumocytoma and its diagnostic criteria]. / K voprosu o gistomorfogeneze i kriteriiakh diagnostiki skleroziruiushchei pnevmotsitomy.

The paper presents the data available in the literature on the pathogenesis, clinical and morphological, histological and immunohistochemical features of pulmonary sclerosing pneumocytoma (SP). The paper gives the detailed histological and immunohistochemical characteristics of 6 SP cases. The need for the differential diagnosis of SP is determined by the features and complexity of their histo- and morphogenesis within a single tumor and a complex diagnostic study.

[The thromboplastic activity of normal and tumorous human tissues]. / Tromboplasticheskaia aktivnost' normal'nykh i opukholevykh tkanei cheloveka.

The study was made of thromboplastic activity of normal, pathological and tumor human tissues using a hemocoagulatory test-system specifically sensitive to apoprotein III-containing membrane structures. It is established that thromboplastic activity of membrane fragments can be inhibited by native cell components. Blood coagulation and fibrin deposition in tissues can go without cell damaging under initiation by increased permeability of vascular walls and plasma contact with surface of the cells located extravascularly.

[The measurement of NMR-1H relaxation time of blood serum as a method of laboratory diagnosis]. / Izmerenie vremeni IaMR-1H-relaksatsii syvorotki krovi kak metod laboratornoi diagnostiki.

Measurement of NMR-1H-relaxation of the blood serum cannot be employed in the differential diagnosis of individual diseases. This method may be useful as an additional test in examination of the time course of a disease in a patient and in mass screenings or prophylactic check-ups.
