[Annual variation in hematological indices in a fluctuating population of bank vole (Clethrionomys glareolus)].

The quantitative and structural hematological indices were studied in bank vole in different reproductive states (overwintered individuals, mature underyearlings, and immature underyearlings) in different years corresponding to different phases of the population cycle. The annual changes in certain hematological indices have been revealed for each reproductive state irrespective of the population cycle phase.

[Fluctuating asymmetry of craniometric characters in rodents (Mammalia: Rodentia): interspecific and interpopulational comparisons].

Ontogenetic instability was studied in four rodent species (Ellobius talpinus, Microtus arvalis, M. rossiaemeridionalis, Mus musculus). It was measured by fluctuating asymmetry (FA) of 21 craniometric characters.

[Nutrients of natural origin for prevention and treatment of radiation disease in experiment].

The preventive and medical effect of some nutrients of plant origin suggested as food supplement was studied in mice subjected to acute irradiation. The evidence of increased radioresistance was revealed.
