Why the study?
Does cooling alter the affinity of alpha-adrenoceptors and contractile responses in canine cutaneous veins compared to deep limb veins?
Does cooling alter the affinity of alpha-adrenoceptors and contractile responses in canine cutaneous veins compared to deep limb veins?
Cooling increases the affinity of alpha-adrenoceptors in cutaneous veins, explaining their augmented contractile response to adrenergic stimulation, an adaptation likely related to chronic exposure to local temperature variations.
No takes yet. Share an insight, caveat, or question.
No immediate clinical implications in humans; leaves open translation of regional venous alpha-adrenoceptor thermosensitivity to thermoregulation or vasospasm.
Janssens et al. (1978) studied this question.
