[Central mechanisms of thermoregulation and phase transitions of brain lipids pertaining to them].

The experiments in rats and rabbits revealed a correlation among the body temperature, the peripheral temperature threshold, central (thermosensitive neurons) thermoregulatory responses, and the temperature of phasic transition of brain lipids three latter parameters rising during experimental fever. The composition of phospholipids changed in hypothalamic tissues, i.e. the level of saturated fatty acids radicals increased.
