Formation of granulocytes and macrophages in mouse bone marrow cultures exposed to various anaesthetics. 1982

H B Benestad, and L J Bjertnaes, and I B Hersleth

The effects of anaesthetics on mouse bone marrow colony growth in vitro were examined. The culture dishes were kept in boxes of stainless steel, so that the composition of the gas phase could easily be controlled. After 1 week of culturing, cell colonies were counted. The cells (macrophages and in one type of culture also granulocytes) were then washed out of the dishes and counted. Enflurane, as well as halothane, present in the gas phase at concentrations used clinically, decreased the number of colonies and cells in a dose-dependent fashion. However, intravenously administered drugs such as diazepam, fentanyl, alfentanyl, sufentanyl, thiopental and pentobarbital were not inhibitory at concentrations used in anaesthetic practice, but at least some of them depressed cell formation when high concentrations were used.

UI	MeSH Term	Description	Entries
D008264	Macrophages	The relatively long-lived phagocytic cell of mammalian tissues that are derived from blood MONOCYTES. Main types are PERITONEAL MACROPHAGES; ALVEOLAR MACROPHAGES; HISTIOCYTES; KUPFFER CELLS of the liver; and OSTEOCLASTS. They may further differentiate within chronic inflammatory lesions to EPITHELIOID CELLS or may fuse to form FOREIGN BODY GIANT CELLS or LANGHANS GIANT CELLS.

D003975	Diazepam	A benzodiazepine with anticonvulsant, anxiolytic, sedative, muscle relaxant, and amnesic properties and a long duration of action. Its actions are mediated by enhancement of GAMMA-AMINOBUTYRIC ACID activity.	7-Chloro-1,3-dihydro-1-methyl-5-phenyl-2H-1,4-benzodiazepin-2-one,Apaurin,Diazemuls,Faustan,Relanium,Seduxen,Sibazon,Stesolid,Valium
D004737	Enflurane	An extremely stable inhalation anesthetic that allows rapid adjustments of anesthesia depth with little change in pulse or respiratory rate.	Alyrane,Enfran,Enlirane,Ethrane,Etran
D005260	Female		Females
D006098	Granulocytes	Leukocytes with abundant granules in the cytoplasm. They are divided into three groups according to the staining properties of the granules: neutrophilic, eosinophilic, and basophilic. Mature granulocytes are the NEUTROPHILS; EOSINOPHILS; and BASOPHILS.	Granulocyte
D006221	Halothane	A nonflammable, halogenated, hydrocarbon anesthetic that provides relatively rapid induction with little or no excitement. Analgesia may not be adequate. NITROUS OXIDE is often given concomitantly. Because halothane may not produce sufficient muscle relaxation, supplemental neuromuscular blocking agents may be required.

D000777	Anesthetics	Agents capable of inducing a total or partial loss of sensation, especially tactile sensation and pain. They may act to induce general ANESTHESIA, in which an unconscious state is achieved, or may act locally to induce numbness or lack of sensation at a targeted site.
