Behavioral, Ventilatory and Thermoregulatory Responses to Hypercapnia and Hypoxia in the Wistar Audiogenic Rat (WAR) Strain
(Public Library Science, 2016-05-05)
Introduction We investigated the behavioral, respiratory, and thermoregulatory responses elicited by acute exposure to both hypercapnic and hypoxic environments in Wistar audiogenic rats (WARs). The WAR strain represents ...
Carotid body chemosensory activity and ventilatory chemoreflexes in cats persist after combined cholinergic-purinergic block
(ELSEVIER SCIENCE BV, 2007)
Acetylcholine (ACh) and ATP have been proposed as excitatory co-transmitters operating at synapses between glomus cells and sensory nerve endings of the carotid body (CB). To test such hypothesis, we performed experiments ...
Ventilation and hypoxic ventilatory response of Tibetan and Aymara high altitude natives
(American Journal Physical Anthropology, 1997)
ABSTRACT Newcomers acclimatizing to high altitude and adult male
Tibetan high altitude natives have increased ventilation relative to sea level
natives at sea level. However, Andean and Rocky Mountain high altitude
natives ...
Chronic phenytoin treatment reduces rat ventilatory responses to acute hypoxia
(2015)
Carotid body (CB) afferent activity drives ventilation from the periphery by changes in arterial gases and pH. Sensory neurons
innervating the CB present a persistent Na+ current (INaP); acute blockade of INaP with phenytoin ...
Branchial O2 chemoreceptors in Nile tilapia Oreochromis niloticus: Control of cardiorespiratory function in response to hypoxia
(2013-09-01)
This study examined the distribution and orientation of gill O2 chemoreceptors in Oreochromis niloticus and their role in cardiorespiratory responses to graded hypoxia. Intact fish, and a group with the first gill arch ...

Hypoxic and hypercapnic ventilatory responses in rats with polycystic ovaries
(Elsevier B. V., 2015)
Chronic phenytoin treatment increases basal ventilation but reduces peripheral ventilatory drive in the anesthetized rat
(2014)
The hypoxic ventilatory response (HVR) in rats depends on the carotid body (CB) chemoreceptors. The acute blockage of the persistent Na+ current
(INaP) in rats reduces the CB chemosensory discharge, the basal ventilation ...
