[Effects of histamine and its derivatives on the excitability of a giant identifiable neuron of Achatina fulica Férussac. A histaminergic receptor different from H1 and H2]. 1976

H Takeuchi, and I Yokoi, and A Mori, and K Horisaka

A giant neurone of Achatina fulica Férussac (the TAN, tonically autoactive neurone) is excited by histamine. Pharmacological characteristics of its histaminergic reception are quite different from those of H1 and H2 receptors. The effect of histamine on the TAN is antagonized by neither mepyramine nor burimamide.

UI MeSH Term Description Entries
D007093 Imidazoles Compounds containing 1,3-diazole, a five membered aromatic ring containing two nitrogen atoms separated by one of the carbons. Chemically reduced ones include IMIDAZOLINES and IMIDAZOLIDINES. Distinguish from 1,2-diazole (PYRAZOLES).
D009474 Neurons The basic cellular units of nervous tissue. Each neuron consists of a body, an axon, and dendrites. Their purpose is to receive, conduct, and transmit impulses in the NERVOUS SYSTEM. Nerve Cells,Cell, Nerve,Cells, Nerve,Nerve Cell,Neuron
D011720 Pyrazoles Azoles of two nitrogens at the 1,2 positions, next to each other, in contrast with IMIDAZOLES in which they are at the 1,3 positions.
D011738 Pyrilamine A histamine H1 antagonist. It has mild hypnotic properties and some local anesthetic action and is used for allergies (including skin eruptions) both parenterally and locally. It is a common ingredient of cold remedies. Mepyramine,Pyranisamine,Anthisan,Boots Bite & Sting Relief,Kriptin,Mepyramine Maleate,Pyrilamine Maleate,Maleate, Mepyramine,Maleate, Pyrilamine
D011968 Receptors, Histamine Cell-surface proteins that bind histamine and trigger intracellular changes influencing the behavior of cells. Histamine receptors are widespread in the central nervous system and in peripheral tissues. Three types have been recognized and designated H1, H2, and H3. They differ in pharmacology, distribution, and mode of action. Histamine Binding Sites,Histamine Receptors,Histamine Receptor,Binding Sites, Histamine,Receptor, Histamine,Sites, Histamine Binding
D002049 Burimamide An antagonist of histamine that appears to block both H2 and H3 histamine receptors. It has been used in the treatment of ulcers.
D006632 Histamine An amine derived by enzymatic decarboxylation of HISTIDINE. It is a powerful stimulant of gastric secretion, a constrictor of bronchial smooth muscle, a vasodilator, and also a centrally acting neurotransmitter. Ceplene,Histamine Dihydrochloride,Histamine Hydrochloride,Peremin

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.

D012908 Snails Marine, freshwater, or terrestrial mollusks of the class Gastropoda. Most have an enclosing spiral shell, and several genera harbor parasites pathogenic to man. Snail
