Cardiac nociception induced rectal response: relation with haemodynamic changes.
Epicardial application of nicotine (200 micrograms/ml) over the left ventricle or occlusion of the left anterior descending coronary artery (LAD) in lightly anaesthetised cats resulted a biphasic change in rectal motility-initial relaxation followed by contraction along with biphasic changes of blood pressure (B.P.) with epicardial nicotine and only hypotension with LAD occlusion. Desensitisati...
متن کاملNociception
Nociception, the sensory mechanism that allows animals to sense and avoid potentially tissue-damaging stimuli, is critical for survival. This process relies on nociceptors, which are specialized neurons that detect and respond to potentially damaging forms of energy - heat, mechanical and chemical - in the environment. Nociceptors accomplish this task through the expression of molecules that fu...
متن کاملP2X receptors and nociception.
The potential importance for nociception of P2X receptors, the ionotropic receptors activated by ATP, is underscored by the variety of pain states in which this endogenous ligand can be released. Several important findings have been made recently indicating that P2X receptors can be involved in pain mechanisms both centrally and in the periphery. The roles of ATP at these two sites and the P2X ...
متن کاملPostoperative Models of Nociception.
Even though it is a costly, poorly understood problem, very little effort has been dedicated toward research on the mechanisms of acute postoperative pain. Presumably, if we learn more about the etiology of acute incisional pain and the sensory processes that intensify pain after surgery, new treatment methods can be advanced. Since the mid-1990s, our group and others have developed and charact...
متن کاملIsoflurane and Nociception
Background: The authors recently established that the analgesic actions of the inhalation anesthetic nitrous oxide were mediated by noradrenergic bulbospinal neurons and spinal 2B adrenoceptors. They now determined whether noradrenergic brainstem nuclei and descending spinal pathways are responsible for the antinociceptive actions of the inhalation anesthetic isoflurane, and which adrenoceptors...
