Effects of inducer pretreatment on liver function and morphology in the mountain vole Microtus montanus. 1987

J R Hincks, and W A Brindley

Liver function and morphology of the mountain vole, Microtus montanus, were examined after i.p. injections of phenobarbital, beta-naphthoflavone, or Aroclor 1254 at three dose levels. The results of the liver function tests showed serum glutamic pyruvic transaminase and serum malathion carboxylesterase activities were normal in all the treatment groups. The histological results showed no necrotic tissue but did reveal two different morphological stages related to the level of monooxygenase activity; a low induction state was represented by foamy vacuolated hepatocytes while high induction states were related to enlarged, swollen, hypertrophied cells.

UI	MeSH Term	Description	Entries
D008099	Liver	A large lobed glandular organ in the abdomen of vertebrates that is responsible for detoxification, metabolism, synthesis and storage of various substances.	Livers
D010634	Phenobarbital	A barbituric acid derivative that acts as a nonselective central nervous system depressant. It potentiates GAMMA-AMINOBUTYRIC ACID action on GABA-A RECEPTORS, and modulates chloride currents through receptor channels. It also inhibits glutamate induced depolarizations.

D001140	Aroclors	Industrial chemicals which have become widespread environmental pollutants. Each aroclor is a mixture of chlorinated biphenyls (1200 series) or chlorinated terphenyls (5400 series) or a combination of both (4400 series).	Aroclor
D001571	Benzoflavones	Organic compounds containing a BENZENE ring attached to a flavone group. Some of these are potent arylhydrocarbon hydroxylase inhibitors. They may also inhibit the binding of NUCLEIC ACIDS to BENZOPYRENES and related compounds. The designation includes all isomers; the 7,8-isomer is most frequently encountered.
