Effects of ketamine on the catecholamine containing cells of the adrenal gland of the lizard Podarcis s. sicula Raf. 1985

L Varano, and V Laforgia, and P De Vivo

The authors studied the effects of ketamine on the morphology of the adrenal gland of Podarcis s. sicula Raf.. Low doses of the drug failed to anesthetize the lizards and did not cause significant changes in the morphology of the adrenal cells. Higher doses of ketamine caused deep anesthesia and marked depletion of catecholamine granules. The results support the theory that ketamine acts on the peripheral autonomic nervous system and sympathetic ganglia.

UI MeSH Term Description Entries
D007649 Ketamine A cyclohexanone derivative used for induction of anesthesia. Its mechanism of action is not well understood, but ketamine can block NMDA receptors (RECEPTORS, N-METHYL-D-ASPARTATE) and may interact with sigma receptors. 2-(2-Chlorophenyl)-2-(methylamino)cyclohexanone,CI-581,Calipsol,Calypsol,Kalipsol,Ketalar,Ketamine Hydrochloride,Ketanest,Ketaset,CI 581,CI581
D008116 Lizards Reptiles within the order Squamata that generally possess limbs, moveable EYELIDS, and EXTERNAL EAR openings, although there are some species which lack one or more of these structures. Chameleons,Geckos,Chameleon,Gecko,Lizard
D008297 Male Males
D002395 Catecholamines A general class of ortho-dihydroxyphenylalkylamines derived from TYROSINE. Catecholamine,Sympathin,Sympathins
D000311 Adrenal Glands A pair of glands located at the cranial pole of each of the two KIDNEYS. Each adrenal gland is composed of two distinct endocrine tissues with separate embryonic origins, the ADRENAL CORTEX producing STEROIDS and the ADRENAL MEDULLA producing NEUROTRANSMITTERS. Adrenal Gland,Gland, Adrenal,Glands, Adrenal
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.
