[Microfluorimetric research on the erythroblastic islands and macrophages of the bone marrow]. / Mikrofliuorimetricheskoe issledovanie éritroblasticheskikh ostrovkov i makrofagov kostnogo mozga.

A microfluorimetric system was used to study rat bone marrow erythroblastic islands (EI) and macrophages. Measurement of fluorescence from acridine-orange-treated cells was performed on the microscope LUMAM-E3 (LOMO, Leningrad) at 530-550 and 630-650 nm. The intensity of fluorescence in 530-550 nm range depended on the intensity of proliferative processes in EI, that at 630-650 nm was associated with activity of lysosomal apparatus of EI macrophages. Erythroblast amplification in EI is parallel both to enhancement of fluorescence intensity at 530-550 nm and 630-650 nm. Intensity of fluorescence of different bone marrow macrophages was evaluated. It is suggested that a part of bone marrow macrophages has high affinity to erythroid tissue.

[Effects of resection of the small intestine on the pressure in the portal vein system in experimental portal hypertension]. / Vliianie rezektsii tonkoi kishki na davlenie v sisteme vorotnoi veny pri éksperimental'noi portal'noi gipertenzii.

A possibility of the portal venous blood flow reduction by means of resection of 1/3 of the small intestine in animals with the model of portal hypertension has been proved. Such an operation was performed in 2 patients, the long-term results are good.
