Protein content in winter triticale grain with different resistance to preharvest germination. pp. 25--27
Summary: The protein synthesising system in two winter triticale genotypes with contrasting germination intensity has been studied in the state of rest and active growth. The specific peculiarities of the system which determine readiness for germination in the state of rest as well as intensity of growth processes have been revealed. The genotypes were characterised by of polysomic complexes in a resting caryopsis.

New computer program to select type of biological data distribution. pp. 28--30
Summary: The article deals with a new PC program BIODIS intended for choosing type of biological data distribution. This program is easy and handy, it can be used as a first step in statistical processing of biological experiments. There are the following types of statistical distributions for choice: Gauss (normal), Poisson, binomial, Maxwell, Student (t), geometric, rectangular. Goodness-of-fit evaluation is realized by means of c2-, w2- or Kolmogorov-tests. The program can be used for small samples and samples with outliers. BIODIS is completely compatible with the spreadsheet manager system TABMAN and the statistical-genetic application program package RISHON designed at the Institute of Genetics and Cytology.

Analysis of ear attraction and productivity components during development of self-fertile forms of diploid winter rye. pp. 31--34
Summary: In changing diploid winter rye from crossbreeding to inbreeding (SF 0--20%) reduction in ear attraction and productivity is observed. With an increase in self-fertility, however, a rise in the values of the above-stated characters takes place. At selffertility above 50--60% the mean values of grain weight per ear and 1000-grain weight approach the initial ones and those for attraction and seed setting exceed them. An important role of attraction in increasing productivity of winter rye during change-over to the inbred method of reproduction was revealed.

Adaptive response in combination with radioprotective effect of melanin in reproductive and somatic cells of mice. pp. 35--36
Summary: Radioadaptive response has been found in bone marrow and reproductive cells of mice -- the genetic effect of the divided radiation dose (0.2 Gy + 1.5 Gy) was about half that of single 1.7 Gy dose. Melanin has been shown to remove completely the low radiation dose effect -- if pigment was used before the first conditioning dose, adaptive response didn't appear. Melanin application after the first conditioning dose led to 4-fold decrease in the aberration level, because both radioadaptive reaction and protection have been observed.

Extracellular phosphohydrolases of filamentous fungus Spicaria violacea. pp. 49--53
Summary: The paper deals with phosphohydrolase activities present in cultural medium of filamentous fungus Spicaria violacea BM--105D. It was revealed that growth of the fungus at acid pH and low inorganic phosphate concentration results in accumulation of RNase, exonuclease, phosphatase, nucleotidase and phosphodiesterase activities in the cultural medium. Enzyme proteins of heterogeneous molecular weight are responsible for the majority of the aforementioned enzyme activities.

Ultrastructural analysis of ovary blood capillaries in 20-day albino rat fetuses irradiated at different periods of ontogenesis. pp. 64--68
Summary: Blood capillary response of 20-day rat fetuses to a single external irradiation dose of 0.5 Gy was studied on 10th and 14th days of their embryonic evolution. It is shown that low dose ionizing radiation changes the morphological expression in capillary cells of important synthetic, transport and energy processes in fetal period of ontogenesis.

Amino acid correction of GABA metabolic shifts in rat brain following ethanol withdrawal. pp. 73--77
Summary: We examined effect of some commercial amino acid compositions (AAC) on transmitter amino acid levels and GABA degradative enzyme activities in brain structures of rats which consumed ethanol solution during 6 months followed by 12 hours ethanol withdrawal (EW). The AAC were injected i. p. by 11 h of EW and 1 h before decapitation. They led to disappearance of behavioral symptoms of EW, increased the GABA shunt activity in the hemispheres, decreased the GABA degradation in the cerebellum and basal ganglia and normalized the amino acid levels altered by EW.

Electrophysiological analysis of duodenal sensitivity to temperature stimuli as affected by capsaicin. pp. 78--82
Summary: Electrical activity of the vagus nerve was studied under temperature effects on the duodenum under capsaicin action in acute experiments with anesthetized cats. The experiments revealed changes of different directions in the impulse activity of vagal afferent fibres, that is an increase in the electrical activity under heating and a decrease under cooling of duodenum. Capsaicin markedly altered afferent impulse responses of the vagus to heating of the duodenum and did not affect changes in the electrical activity induced by cooling.

Efferent impulsation of cervical sympathetic nerve and systemic blood pressure under ischemia-reperfusion of rat small intestine. pp. 83--86
Summary: In acute experiments on rats it was shown that occlusion of mesenteric vessels of a jejunal segment (4--5 cm) for 15 min or 1 hour led to inhibition of efferent impulse activity in the cervical sympathetic nerve and to increase in systemic blood pressure. The blood pressure irreversibly decreased and the sympathetic activity diminished during reperfusion after prolonged ischemia.

Interaction of human polyclonal immunoglobulins G with metal cations. pp. 90--96
Summary: Interactions between human donors lgG (subclasses G1, G2, G4) and different metal (Me) ions (Mg(II), Ca(II), Cu(II), Zn(II), Ni(II), Co(II), Fe(II), Cr (III)) using metal-chelate chromatography on iminodiacetic acid matrix were investigated. It was found that Me cations differed in their ability to bind lgG molecules. Elution experiments using different amino acids showed that 100% of adsorbed lgG was eluted with Cys solution, 42.5% -- with Hys, 11.9% -- with Glu. Estimation of possible enzyme-like (abzyme) action of lgG-Me complexes demonstrated some lgG-Me catalytic activities. The acceleration of hydrogen peroxide hydrolysis due to lgG-Cu complex was demonstrated. Low but distinct BAPNA-amidase activity of lg-Cu was also revealed. It can be concluded that lgG capable to interact with Me ions may play a role in vivo as metal-binding proteins and/or enzyme-like active agents.

Differential X-ray diagnosing of large intestine contractions. pp. 97--100
Summary: Comparative X-ray analysis of local constrictions characteristic of spasms, inborne strictures, irritated large intestine, chronic ulcer colitis, cancer, other diseases manifesting symptoms of chronic intestinal congestion was performed. Successful diagnosing was found to depend on qualified X-ray examination of large intestine and true interpetation of the pictures. Segmentary investigation would be desirable by applying ray visualisation techniques.

Origination of allergodermatite hotbed in lake Naroch. pp. 104--107
Summary: The paper centers on the origin of dermatites caused by cercaria of trematodes from the family Schistosomatidae (Loos, 1899) in the lake Naroch. Hotbed inception was triggered by aggregation of waterfowl hosting such specific parasites as Trichobilharzia ocellata (La Valette, 1845) and Bilharziella polonica (Kowalewsky, 1895). Another reason is mass breeding of pulmonate molluscs -- intermediate trematode hosts.

Fertility and reproduction of wolves in Belarus. pp. 108--110
Summary: The materials on withdrawal of 713 cubs from 114 wolf broods in Belarus have been analysed. The brood size was estimated. The variability of this parameter in three ecological regions was traced and its dependence on density of predator population and quota of withdrawal of adult animals has been shown. The percentage of reproducing females in population and cubs mortality during first month of life were calculated. The obtained results demonstrate high wolf viability and define the withdrawal size optimal for maintenance of predators on the certain balanced level.
