The indicators of hybrid progeny fertility of secondary potato dihaploids. pp. 45--52.
Summary: It has been ahown that flowering intensity and pollen quantity in hybrid progeny of fertile secondary potato dihaploids are rather high. At the same time the level of pollen functional fertility in more than half of hybrids analyzed was lower the suitable for the hybridization threshold (5% of pollen grains germinated in vitro). The low pollen functional fertility is evidently one of the main factors limiting effective application of potato breeding at the diploid level.

Radioprotective affect of melanin on mice germ cell under acute and chronic irradiation. pp. 57--61.
Summary: The influence of melanin isolated from human hair on genetic effects of acute and chronic irradiation in mice has been investigated. Melanin suspension in sturch gel or gel were intro duced into the stomach of mice which were than irradiated with 3 Gy of g-rays from Cs137 source at the dose rate 29 Gy/min or 0.007 Gy/h. The levels of reciprocal translocations in spermatogonia were analyzed cytologically. It was shown that melanin itself did not possess mutagenic activity. Melanin application at a dose of 50 mg/kg carried out 3 hours before acute irradiation decreases the frequency of radiation induced mutation by a factor of 2. Melanin applications administered every morning at a dose of 1, 3, 10, 30 mg/kg during chronic irradiation were not less but even more effective as compared with acute irradiations.

Culture condition optimization during tissue culture propagation of Lilium. pp. 75--78.
Summary: Tissue culture propagation of Lilium (for the varieties of Botanical Garden of the National Academy of Science of Belarus) was achieved by experimental fashion. The best result was received on Mirashige--Skoog agars media, containing 0.1 mg/l NAA and 1.0 mg/l kinetin. Sucrose concentrating should be increased at the first stage to 30 g/l, at the second passage -- 70 g/l. Regeneration plants were adapted to in vivo condition.

Condition for D-glucose isomerisation by cells of bacteria Arthrobacter sp. and actinomycetes Streptomyces. pp. 91--95.
Summary: Conditions for D-glucose isomerization into D-fructose by cells of bacteria Arthrobacter sp. and actinomycetes S. viridobrunneus, Streptomyces sp.1 and Streptomyces sp. 32 have been studied. Mg2+ ions at 0.005 M concentration are essential in the reaction mixture for maximal glucose isomerase activity in Arthrobacter sp. and S. viridobrunneus cells and at 0.004 M for cultures of Streptomyces sp.1 and Streptomyces sp.32. Top glucose converting activity was observed in cells of Arthrobacter sp., S. viridobrunneus and Streptomyces sp. 32 at pH 8.0 and in Streptomyces sp. 1 at pH 7.5 in temperature range 70--75°C.

Adrenal cortex glucocorticoid function and complex formation capacity of blood corticosteroid-binding globulin after thyroidectomy in rats. pp. 96--100.
Summary: The condition of adrenal cortex glucocorticoid function and complex formation parameters of blood corticosteroid-binding globulin (CBG) were studied after bilateral thyroidectomy (TE) in rats. It was demonstrated that the blood plasma and adrenal corticosterone (K) concentrations as well as the CBG binding parameters were maintained at the control levels during 8 weeks after TE, with the blood thyroid hormones concentrations being significantly decreased (10--30% from the control). We found a statistically significant reduction of the binding sites concentration on CBG and a pronounced tendency to decreasing the K blood plasma concentrations in the cases of acute postoperative hypothyroidism (72 hours, 1 week after TE). The Data obtained suggest that the glucocorticoid function of the adrenal cortex is maintained within the range of control values after bilateral TE. Blood plasma CBG plays an important role in the maintenance of functional activity of the hypophysis-adrenal system in hypothyroidism. The possible role of thyroid hormones in CBG activity regulation is discussed.

Brean and roach gametogenesis under radionuclid contamination of Belarus water reservoirs. pp. 115--120.
Summary: The paper presents the results of histological analysis of bream and roach oocytes under radionuclide contamination of water reservoirs after Chernobyl accident. The oocytes degenerative alterations (changes of oocytes asynchronous growth character, oocytes resorption, changes of oocytes envelop structure) in the investigated fish were identified. It was shown that the alterations are bound up with the radionuclide environment contamination level and radionuclide concentration in fish tissues and organs.

The structure of carabit beetle communities (Coleoptera, Carabidal) in the pine plantation of the Bialowiez National Park. pp. 121--125.
Summary: The species composition, domination structure and biological spectrum of carabid beetles have been studied in the pine plantations of the Bialowiez National Park. Totally 36 species were collected in the studied sites. Some rare species for the territory of Belarus were found (Carabus intricatus L., Harpalus hirtipes (Panz.) and Pterostichus quadrifoveolatus (Letzn.)). The plantations of both ages was very similar with each other by the carabid beetle species composition (similarity index is 82%). Three species prevailed in both plantations: Carabus arvensis Herbst, Calathus micropterus (Duft.) and Pterostichus oblongopunctatus (F.). Zoophages are prevailed in the biological spectrum. The typical forest community has formed in pine plantations.
Summary: Subspecies status of Oistercatchers from spatially separated groups with contemporary rapprochement ranges in Belarus is discussed. On the base of morphological index (bill length) two subspecies H. o. ostralegus and H. o. longipes were determined. The fact of partly coincidence of subspecies ranges was established on the first time. Most probably intergradation will extend because of the existing trend of H. o. longipes to further expansion in North-west direction.
