[Formation of artificial nitrogen-fixing symbiosis with rape (Brassica napus var. napus) plants in nonsterile soil].

The treatment of rape plants grown in nonsterile soil with 2,4-dichlorophenoxyacetic acid (auxin-like growth-promoting substance) or their inoculation with the bacterial association Micrococcus sp. + Rhodococcus sp. and/or with the mixed nitrogen-fixing culture Azotobacter nigricans + Bacillus sp.

[The effect of helium-neon laser radiation on the energy metabolic indices of the myocardium].

It was shown in experiments on white rats, that intravenous and direct myocardium helium-neon laser irradiation leads to the some activation of lactate, glucose-6-phosphate, succinate and reduced NAD degydrogenases. During direct myocardium irradiation these changes are in a less degree. It is suggested that helium-neon laser irradiation displays some active influence on the energy metabolism enzymes of the myocardium, and the mechanisms of this action are discussed.

[Effects of T-activin on the morphology of the thymus gland in experimental injury of the lower limbs in mice (anti-stress effect of T-activin)].

The effect of T-activin on thymic involution under the experimental trauma of femur was studied. T-activin in a dose of 1.0 micrograms/mouse was injected into young male (CBA X C57BL)F1 mice weighing 17.

[Thymus involution and recovery in mice after the administration of lipopolysaccharide].

The single injection of 50 micrograms LPS induces polyclonal immune response in the spleen of (CBA x C57B1/6) F1 mice. It is accompanied by the thymic involution and depletion of blasts and mitoses, as showed morphometric analysis. Vinblastin does not induce: accumulation of the mitoses during the first and second days after LPS injection.

[Effect of T-activin on thymus involution in mice].

The effect of T-activin on thymus involution in mice was studied. T-activin in a dose of 1.0 micrograms/mouse was injected into young male (CBA X C57BL)F1 mice weighing 24.
