[Seasonal changes in the function of mechanosensitive receptors in the rat skin].

The effect of circannual rhythms on functional properties of the rat skin tactile receptors and nocireceptors, was studied. The effect proved to be quite significant for the cutaneous receptors threshold stimuli and for the parameters of their responses: the latency and AP duration. These changes seem to be determined by hormonal mechanisms.

[Dynamics of the restoration of the function of the skin receptor apparatus after cryogenic damage to the sciatic nerve].

The stages of degeneration and regeneration of the receptor system of sole skin after cryogenic damaging of the nerve were investigated using the method of impulse activity registration from single fibres of white rat sciatic nerve in acute experiment under hexenal anesthesia. The mechanism of pain syndrome and peculiarities of the development processes of the nerve and skin receptors repair after cryogenic trauma are discussed.
