[The effect of EDTA on the impulse activity of cold thermoreceptors and mechanical cold receptors in rabbits under deep skin cooling].

The EDTA restored the bioelectrical activity and increased its rate in majority of the skin cold thermoreceptors and mechano-cold receptors of the nasolabial area after deep cooling of the skin in anesthetised rabbits. The data obtained suggest that a decrease in the calcium level in the blood lowers the temperature thresholds of the activity of these receptors.
