Dynamics of the Infestation Intensity and Egg Production in Carcinogenesis and Partial Hepatectomy in the Setting of Superinvasive Opisthorchiasis.

Clinical and experimental studies have shown that opisthorchii tend to evade tumour growth foci to colonize more distant areas of the liver. When modelling tumours with various carcinogens in the setting of superinvasive opisthorchiasis, the intensity of invasion is reduced both before the formation of neoplasms (>120 days) and after the development of tumours of various histogeneses (liver, pancreas, and stomach) (>240 days). Egg production was observed to increase with the decrease in the number of parasites in the liver.

Effects of temperature on biological activity of permafrost microorganisms.

The number and viability of microorganism specimens Bacillus spp. isolated from permafrost soil remained unchanged after incubation at temperatures of -16-37°C. Experiments on F1 CBA/Black-6 mice showed that incubation of bacteria at -5°C for 72 h promotes a decrease in their toxicity and an increase in their immunostimulating effect.

Effects of low-doses of Bacillus spp. from permafrost on differentiation of bone marrow cells.

The effects of a new microorganism species (Bacillus spp., strain M3) isolated from permafrost specimens from Central Yakutia (Mamontova Mountain) on the bone marrow hemopoiesis were studied on laboratory mice. Analysis of the count and immunophenotype of bone marrow cells indicated that even in low doses (1000-5000 microbial cells) these microorganisms modulated hemopoiesis and lymphopoiesis activity.

Effects of short-term local warm and cold applications to the chest on immunophysiological parameters of the organism.

Applications of cold and warm activated cellular immunity and orientation and exploratory behavior in mice. Application of cold increased the number of turns to the left in the open field, muscle force, and activity of the food instinct, and caused an increase in the total count of peripheral blood leukocytes. Warm applications reduced the food instinct activity and stimulated the humoral immunity.
