[Flow cytometry evaluation of the rhesus monkey cellular immunity following the Zaire ebolavirus (Filoviridae; Ebolavirus: Zaire ebolavirus) experimental infection].

Introduction: The outbreaks of the Zaire ebolavirus (ZE) disease (ZED) that have arisen in the last decade determine the need to study the infection pathogenesis, the formation of specific immunity forming as well as the development of effective preventive and therapeutic means. All stages of fight against the ZED spread require the experimental infection in sensitive laboratory animals, which are rhesus monkeys in case of this disease .The aim of the study is to evaluate the rhesus monkey cellular immunity following the ZE experimental infection by the means of flow cytometry (cytofluorimetry).

[Exfoliative cytological diagnosis of lung cancer with bronchoscopic material].

Analysis of the results of exfoliative cytological diagnosis of lung diseases from fibrobronchoscopic materials in the presence of the affected bronchial mucosa made it possible to verify lung cancer in 75.9% of cases and to give a descriptive reply due to the fact that cytological specimens were of no diagnostic value. Further examinations of transthoracic puncture specimens and clinical and X-ray findings of patients from the latter group could reveal an inflammatory process in two thirds of cases and peripheral lung cancer in a third.

[Sex ratio in Down syndrome. Estimation of chromosome 21 non-disjunction during spermatogenesis].

Derivation of a formula for determination of proportion of paternal trisomy 21 is presented. The formula can be applied for the literature data on sex ratio in the cases of paternal and maternal origin of the extra chromosome in the populations where direct studies of its origin can not be performed.
