[Technical difficulties raised by the suppression of ventilatory responses from peripheral chemoreceptors in the rat]. 1984

D Lagneaux

In normal pentobarbitalized Wistar rats, simultaneous section of Hering nerves and resection of superior cervical sympathetic chain, suppress chemosensibility, in 50% cases: ventilatory responses to cyanide and to hypoxia are completely suppressed by the surgical denervation. Vagotomy completes loss of chemosensibility in a few animals, indicating the presence of intrathoracic chemoreceptors of minor importance. Local anaesthesia with lidocaïne of extra craniobasal unidentified structures, is as effective as surgical chemodenervation for suppressing ventilatory responses. This technic is not suitable for experimental purposes in long duration assays.

UI	MeSH Term	Description	Entries
D008012	Lidocaine	A local anesthetic and cardiac depressant used as an antiarrhythmia agent. Its actions are more intense and its effects more prolonged than those of PROCAINE but its duration of action is shorter than that of BUPIVACAINE or PRILOCAINE.

D012119	Respiration	The act of breathing with the LUNGS, consisting of INHALATION, or the taking into the lungs of the ambient air, and of EXHALATION, or the expelling of the modified air which contains more CARBON DIOXIDE than the air taken in (Blakiston's Gould Medical Dictionary, 4th ed.). This does not include tissue respiration (	Breathing
D002628	Chemoreceptor Cells	Cells specialized to detect chemical substances and relay that information centrally in the nervous system. Chemoreceptor cells may monitor external stimuli, as in TASTE and OLFACTION, or internal stimuli, such as the concentrations of OXYGEN and CARBON DIOXIDE in the blood.

D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.
