Cyclic AMP mediated activity stimulation by metronidazole in rat liver. 1979

M Beskid, and J Sadowski

In the homogenate of the liver biochemically examined 45 hrs after a single 250 mg dose of metronidazole administration, a 45% increase of c-AMP level was found as compared with controls. A marked proliferation of hepatic smooth endoplasmic reticulum was observed. In the light microscope numerous mitotic figures could be seen. No mitotic figures were present in the liver tissue of either treated or untreated animals examined 24, 72 and 120 hrs post administration of metronidazole. Two points seem of interest in the biologic properties of metronidazole: one is the participation of hepatic smooth endoplasmic reticulum in its metabolism, the other--the formation of active metabolites which may posses carcinogenous properties.

D008795	Metronidazole	A nitroimidazole used to treat AMEBIASIS; VAGINITIS; TRICHOMONAS INFECTIONS; GIARDIASIS; ANAEROBIC BACTERIA; and TREPONEMAL INFECTIONS.	2-Methyl-5-nitroimidazole-1-ethanol,Bayer 5360,Clont,Danizol,Flagyl,Gineflavir,Metric,MetroGel,Metrodzhil,Metrogyl,Metronidazole Hydrochloride,Metronidazole Monohydrochloride,Metronidazole Phosphate,Metronidazole Phosphoester,Satric,Trichazol,Trichopol,Trivazol,Vagilen,2 Methyl 5 nitroimidazole 1 ethanol
D008854	Microscopy, Electron	Microscopy using an electron beam, instead of light, to visualize the sample, thereby allowing much greater magnification. The interactions of ELECTRONS with specimens are used to provide information about the fine structure of that specimen. In TRANSMISSION ELECTRON MICROSCOPY the reactions of the electrons that are transmitted through the specimen are imaged. In SCANNING ELECTRON MICROSCOPY an electron beam falls at a non-normal angle on the specimen and the image is derived from the reactions occurring above the plane of the specimen.	Electron Microscopy
D008938	Mitosis	A type of CELL NUCLEUS division by means of which the two daughter nuclei normally receive identical complements of the number of CHROMOSOMES of the somatic cells of the species.

D000242	Cyclic AMP	An adenine nucleotide containing one phosphate group which is esterified to both the 3'- and 5'-positions of the sugar moiety. It is a second messenger and a key intracellular regulator, functioning as a mediator of activity for a number of hormones, including epinephrine, glucagon, and ACTH.

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.
