[Peculiarities of application of a cell saver apparatus in neonathal cardiosurgery using artificial blood circulation].

Elaborated and introduced into the practice method of the blood preservation, while correction of complex inborn heart failures (IHF) in a newborn babies, was proposed. It assumes application of system for intraoperative reinfusion of own erythrocytes with processing of residual perfusate and their reinfusion in a postperfusion period. Impact of the blood preservation on volume of a donor's blood components, hematological indices and methods of application of washed erythrocytes while correction of complex IHF in a newborn babies were presented.

[The effect of Amanita phalloides poison on the ultrastructure of neutrophilic granulocytes].

Changes of the ultrastructure of neutrophil granulocytes under the effect of Amanita phalloides was manifested by destabilization of cytoplasmic and organoid membranes, degranulation of the cytoplasm, appearance of areas of autolysis and lysed cells. The degree of destruction rose with increase of the dose and incubation time.

[Ultrastructure of donor blood lymphocytes incubated with Amanita phalloides poison].

Heparinized donor blood was investigated incubated with Amanita Phalloides poison in the dose of 0.05 and 0.5 LD100 during 1 and 3 hours.

[The effect of death cup poison on the morphology of human erythrocytes].

Incubation of heparinized blood of donor (37 degrees C) resulted in an insignificant amount of changed erythrocyte, forms mainly at the expense of stomatocytes and echinocytes, reduction of medium diameter and sphericity index. In incubation of blood with Amanita phalloides [correction of Agaricus bulbosus] poison (0.5LD100) changed forms made up 66.

[The cytogenetic effects of separate and combined exposures to a manganese dioxide aerosol and wide-band noise].

Negative cytogenetic effects of manganese dioxide aerosol and noise (40-12,000 Hz, 80-100 dB) were studied. The modification of aerosol's effects by the noise was found.

[Evaluation of the role of specific antimeningococcal antibodies in the spread of meningococcal carrier states in collectives].

The results of serological, bacteriological and epidemiological studies carried out in populations with different epidemic pattern of meningococcal infection are presented. A-group specific antibody was found to have the leading role in the intensity of the spread of meningococcal infection in the populations. The presence of antibody to this antigen in 16.

[Epidemiological and laboratory criteria in the assessment of meningococcus carrier state].

A study was made of the duration of meningococcus carrier state, immunological indices and group-specific properties of meningococci isolated from them. The periods of meningococcus discharge were studied in 738 persons. Three categories of the carrier state were revealed: a single discharge (67% of the carriers), of average duration (up to 4 weeks), and prolonged.

[Role of meningococcal carrier state in formation of the immunologic structure of a collective with regard to that agent].

The authors present the results of the immuno-epidemiological studies of two collective bodies -- over 2000 persons in all -- equal by age composition and physical load, who were under the same sanitary-hygienic conditions. Observations were carried out from the time of formation of these collective bodies in November and were continued for a period of 6 months; they differed by the epidemic situation in respect to the meningococcus infection, i.e.
