The specific binding of [3H]flunitrazepam was studied to biochemically specify the morphological alterations induced in mouse cerebellum by a single injection of an antimitotic agent, methylazoxymethanol (MAM) performed at the beginning of the postnatal life. The MAM injection causes a general reduction of the benzodiazepine receptors in the adult mice which is particularly severe in mice having been injected the 1st day of postnatal life (so-called MAM0 mice) as compared to animals injected the 5th day (MAM5 mice): in MAM0 mice the benzodiazepine receptor is reduced to half of the control value. The affinity of the benzodiazepine towards its receptor was not affected and the topographic and biochemical action of MAM in the central nervous system was ascertained. Correlations could be made between the biochemical modifications and the morphological alterations otherwise described.

UI	MeSH Term	Description	Entries
D008746	Methylazoxymethanol Acetate	The aglycone of CYCASIN. It acts as a potent carcinogen and neurotoxin and inhibits hepatic DNA, RNA, and protein synthesis.	(Methyl-ONN-azoxy)methanol Acetate,Acetate, Methylazoxymethanol
D011963	Receptors, GABA-A	Cell surface proteins which bind GAMMA-AMINOBUTYRIC ACID and contain an integral membrane chloride channel. Each receptor is assembled as a pentamer from a pool of at least 19 different possible subunits. The receptors belong to a superfamily that share a common CYSTEINE loop.

D002531	Cerebellum	The part of brain that lies behind the BRAIN STEM in the posterior base of skull (CRANIAL FOSSA, POSTERIOR). It is also known as the "little brain" with convolutions similar to those of CEREBRAL CORTEX, inner white matter, and deep cerebellar nuclei. Its function is to coordinate voluntary movements, maintain balance, and learn motor skills.	Cerebella,Corpus Cerebelli,Parencephalon,Cerebellums,Parencephalons
D005445	Flunitrazepam	A benzodiazepine with pharmacologic actions similar to those of DIAZEPAM that can cause ANTEROGRADE AMNESIA. Some reports indicate that it is used as a date rape drug and suggest that it may precipitate violent behavior. The United States Government has banned the importation of this drug.

D000477	Alkylating Agents	Highly reactive chemicals that introduce alkyl radicals into biologically active molecules and thereby prevent their proper functioning. Many are used as antineoplastic agents, but most are very toxic, with carcinogenic, mutagenic, teratogenic, and immunosuppressant actions. They have also been used as components in poison gases.

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.
