[Rhabdomyosarcoma of the breast in girls]. / Rabdomiosarkoma molochnoi zhelezy u devochek.

Cases of rhabdomyosarcoma (RMS) in 14 year old girls are described. The tumor was very aggressive with early and widespread metastases in regional and other lymph nodes, soft tissues, various parts of the skeleton, bone marrow, lungs. The diagnosis and spread of this tumour was established on the basis of total examination of the girls. Clinical stage III was found in one girl, stage IV in two patients with RMS of the breast. Diagnoses were confirmed histologically (open biopsy of the tumours). Bilateral alveolar RMS of the breast (synchronic or metachronic) was diagnosed in all the patients. Light and electron microscopies were insufficient for final diagnosis, histogenesis of the tumour was established by means of immunohistochemistry. All the patients died within 3 months to one year and half after diagnosis.

[Formalized macroscopic description and computer analyser of macroscopic image (as illustrated by gastric pathology)]. / Formalizovannoe makroskopicheskoe opisanie i komp'iuternyi analizator makroskopicheskogo izobrazheniia (na primere issledovaniia patolodii zheludka).

A computer analyzer is regularly used in the department of pathology in formalized macrodescription of the stomach. Advantages of this method are described.

[Potential hosts and routes of the circulation of Yersinia pseudotuberculosis in an aqueous ecosystem]. / Potentsial'nye khoziaeva i puti tsirkuliatsii Yersinia pseudotuberculosis v vodnoi ekosisteme.

The interaction between Y. pseudotuberculosis and different representatives of the aqueous and, partially, soil biocenosis was studied. The study revealed that invertebrates of the plankton and benthos (water fleas, cyclops, mollusks, Oligochaeta, larvae of insects), as well as fish and higher plants, ensured the prolonged existence of Yersinia in water. Thus hydrobiotic organisms were to be regarded as potential natural hosts of Y. pseudotuberculosis. A suggestion was made that fish, the final link of some alimentary chains, could present epidemic danger as a food product for human consumption.

[Antiviral and immunostimulating effect of maleic anhydride copolymers in experimental neuroviral infections]. / Protivovirusnyi i immunostimuliruiushchii éffekt sopolimerov maleinovogo angidrida pri éksperimental'nykh neirovirusnykh infektsiiakh.

The virus-inhibiting and immunostimulating activity of Soviet preparations, maleic anhydride copolymers, was demonstrated in alpha-, flavi-, and bunyavirus infections. Positive results were obtained in subcutaneous and intraperitoneal inoculations of the preparations used in prophylactic and therapeutic-prophylactic schedules. Stimulation of vaccination immunity was observed after combined use of copolymers and the vaccine against Eastern equine encephalomyelitis.
