[Changes in the functional activity of macrophages of the skin and regional lymph node after exposure of albino rats to total deep hyperthermia].
In the experiments performed on white male rats (150-170 g of body mass) effect of total deep hypothermia has been studied in macrophages of the skin and regional suprascapular lymph node of various localization: Langerhans cells of the epidermis, histiocytes of the derm and hypoderm, macrophages of medullary sinuses, interdigitating cells of T-zones in the lymph node. After narcotization the animals are cooled with the rate 1 degree C per 5 min up to the rectal temperature of 18 degrees C. They are kept at this temperature for 2 h, and then are warmed with the same rate up to 37 degrees C. Actively phagocytizing macrophages of the skin and lymph node are revealed by their adsorption of trypan blue. The Langerhans and interdigitating cells of the lymph node are revealed by means of the ATP-ase method. After the cooling effect functional activity of macrophages with various localization increases. For the Langerhans cells it is manifested as a greater amount of the cells and their processes, for the interdigitating cells--as an elevated ATP-ase activity in 7 and 30 days after the experiment. Dermal histiocytes and macrophages of the lymph node sinuses respond to the cooling with an increasing adsorption of tripan blue. Amount of the cells, that adsorb the dye also increases. A conclusion is made that after the hypothermal effect protective-barrier properties of the dermal region increase.
