Adrenoreactivity at acute cold shock

The analysis of reactance of arteries of rabbits on mimetics after unitary cooling acute cold shock (ACS) has shown, that sensitivity an alpha-1-adrenoreceptors of arteries of skin-muscular area decreases on 6 % at simultaneous increase of quantity active an alpha-1- adrenoreceptors on 115%. It is revealed, that in arteries of kozhno-muscular area after unitary cooling sensitivity an alpha-2- adrenoreceptors on 66,5% decreases at increase of quantity active an alpha-2- adrenoreceptors on 150%. As a result of the spent researches it is proved, that at adaptation to a cold there is an increase in reactance of arteries exclusively at the expense of increase in them quantities active an alpha-1 and an alpha-2 adrenoreceptors. Though sensitivity of both types of receptors is lowered.
