Path analysis of agronomic characters in yellow lupine (Lupinus luteus L.). pp. 23--29
Summary: As a result of correlation and path analyses it was revealed that highly variable character such as seed number in major inflorescence exerted the highest direct influence on seed productivity of Lupinus luteus L. So selection of high-productive genotypes should be performed for the given character.

Use of variance analysis in ecological and physiological investigations of sown grass communities. pp. 30--35
Summary: The paper presents an application of the variance analysis for ecological and physiological investigations of plant relations in phytocenoses. The proposed scheme gives the possibility to determine the quantitative contribution (2 %) of both the abiotic factors and the cenotic ones. The role of nitrogenous fertilizers and the effect of the competition between the species in the protein content in leaves are demonstrated in double grass mixtures of Medicago sativa L. and Phleum pratense L. Our interpretation of variance method in reference to phytocenology is shown to define the main trends in physiological investigations in this field.

Estimation of phenotypic variability in anatomic parameters of flax stem. pp. 63--68
Summary: Phenotypic variability of stem anatomic parameters in the lower, middle and the upper parts has been estimated in 12 flax samples of the local and foreign breeding. The greatest differences between the varietes obtained were revealed in the middle part of the stem. The number of fibres on the cut in the lower and middle part of the stem, the number of bunches on the cut in the upper part, as well as the number of fibres per circumference length unit in the middle part appeared to be the most variable. Estimated in this paper are qualitative and quantitative characteristics of flax varieties based on their stem anatomic parameters.

Melanin pigments of some mycelium fungi. pp. 68--73
Summary: Monocyclic compounds (pyrocatechol a.o.) were revealed to exert the greatest stimulating effect on melanogenesis of macromycete Phellinus robustus and a bicyclic compound -- naphthol -- on micromycete Alternaria alternata. Differences between electronic and IR spectra, as well as between molecular weights and optic properties of melanin complexes of these fungi were revealed. These data make it possible to suppose that melanin complexes of various fungi may be attributed to different types.

The influence of hydroxythiamine asymmetric disulphide structure on their inhibitory properties for thiamine enzymes. pp. 74--76
Summary: It was shown that inhibitory action on the transketolase and pyruvate dehydrogenase of hydroxythiamine asymmetric disulphides with normal hydrocarbon chains (C3 -- C9) is determined by hydrophobic and electronic properties of aliphatic groups.

Carnitine in riboflavin-deprived rats. pp. 77--80
Summary: Concentration of free and acylcarnitines has been measured in tissues and biological fluids of control and vitamin B2-deficient rats. Decreased levels of free carnitine were seen in plasma, muscle, kidney and liver of vitamindeprived rats. L-carnitine supplementation increased the tissues free carnitine and acylcarnitine concentrations in riboflavin-deficient rats.

Absorption of pantothenic acid by brush-border membranes of rat small intestine. pp. 80--84
Summary: Pantothenate transport through the brush-border membrane of the rat small intestine is mediated by a Na+-dependent carrier-mediated process. An initial rate of pantothenate transport as a function of concentration is saturable. Furthermore, the results indicate that pantothenate transport by the Na+-dependent process probably occurs by a pantothenate-Na+ contransport mechanism.

The influence of some nitro compounds on lipid peroxidation process in rat brain- and liver cells. pp. 86--90
Summary: As one can see from the data of our investigations, nitrogencontaining xenobiotics caused dissimilar changes in the content of the primary and final products of lipid peroxidation. The purpose and expression of these changes depend on the way of administering preparation, the post-effect time and on the tissue studied.

The influence of PGH carbocyclic analogues with modified chains on proliferation of Ehrlich ascite tumor cells. pp. 91--94
Summary: The influence of different concentrations (10-8 -- 10-6 M) of 3 new compounds of PGH carbacyclic analogues with modified chains, attributable to 7-oxo-9,11-ethanoprostanoids, on proliferation of Ehrlich ascite tumor cells in 3-day explanted cultures was studied by the values of proliferation index and inhibitory effect. Only 2 compounds were revealed to inhibit Ehrlich ascite tumor cell in vitro proliferation to the greatest extent at all 3 concentrations studied corresponding to real concentrations for in vivo conditions for PG analogues: at 10-7 M concentration the compound with 1-nor-7-oxoalcyl fragment in alpha-chain displays the utmost inhibitory effect in 39%, while the compound with isoxazole and imidazole groups in omega-chain displays the utmost inhibitory effect in 45%. PG endoperoxide analogue with pyrazole fragment in omega-chain at 10-6 M concentration stimulates the tumor cell proliferation by 44%.
