Modification of the main parameters of cholinergic reactions in rabbits, i.e., of the specific sensitivity to agonists (EC50), maximal reaction values (Pm) of arterial pressure in the hind limb vessels and small intestine in situ, and systemic arterial pressure after adaptation to cold for 1, 5, 10, and 30 days has been investigated. The depressor reaction(More)
It was assumed that α -adrenergic receptors of the CNS play the key role in the development of cardiovascular response to acute cold stress in rats [13]. Adaptation of rabbits to low temperatures increases the sensitivity and decreases the maximal α -adrenergic response of systemic blood pressure to noradrenalin on the day 1–30 of adaptation. These changes(More)
Changes in major paraments of alpha 1- and beta-adrenergic responses (EC50 and Pm) were studied in the intestine arterial blood vessels of rabbits adapted to cold for 1-30 days (daily cold exposures for 6 hours at -10 degrees C). It was shown that responses to phenylephrine, noradrenaline, adrenaline (alpha 1-agonists), isopropylnoradrenaline (beta-agonist)(More)
Changes in major parameters of alpha 1-, alpha 2- and beta-adrenergic responses (EC50 and Pm) were studied in hind-limb arterial vessels of the rabbits adapted to cold for 1-30 days (daily cold exposures for 6 hours at -10 degrees C). It was shown that responses to phenylephrine, noradrenaline, adrenaline (alpha 1-agonists), clondine (alpha 2-agonist),(More)
Changes in the main parameters of alpha- and beta-adrenergic responses, sensitivity to agonists (EC50) and maximum response (Pm) of hindlimb and small intestinal blood pressure in situ and systemic blood pressure were studied in rabbits adapted to cold for 1-30 days (daily exposures to -10 degrees C for 6 h). The responses to phenylephrine, noradrenaline.(More)
Long-term or repeated exposure to either high or low temperature leads to an adaptive reorganization of all systems in a human or animal body. The connection of thermoregulation with the sympathetic nervous system was reviewed in general in a monograph by Gurin [1]. Published data on the changes in human arterial blood pressure in regions with low air(More)
Changes in major parameters of alpha1-adrenergic and muscarinic cholinergic responses of arterial blood pressure (EC50 and P(m)) were studied in rabbits adapted to cold for 1-30 days (daily cold exposures for 6 hours at -10 degrees C). It was shown that responses to noradrenaline, adrenaline (agonists of alpha1-adrenoceptors) and acetylcholine (agonist of(More)
