Loss of intrinsic striatal neurons after methylazoxymethanol acetate treatment in pregnant rats. 1984

W Balduini, and M P Abbracchio, and G Lombardelli, and F Cattabeni

Treatment of pregnant rats with methylazoxymethanol (MAM) induces a marked microencephaly in the offspring. The striatum is one of the brain areas affected by treatment. We show that in striatum there is a 30% loss of dopamine (DA)-dependent adenylate-cyclase activity: this indicates that cells bearing type 1 DA receptors are affected by MAM treatment. Moreover, since kainic acid retains its neurotoxic activity, corticostriatal fibers do not seem to be affected, despite the dramatic reduction of cortex size.

UI MeSH Term Description Entries
D007608 Kainic Acid (2S-(2 alpha,3 beta,4 beta))-2-Carboxy-4-(1-methylethenyl)-3-pyrrolidineacetic acid. Ascaricide obtained from the red alga Digenea simplex. It is a potent excitatory amino acid agonist at some types of excitatory amino acid receptors and has been used to discriminate among receptor types. Like many excitatory amino acid agonists it can cause neurotoxicity and has been used experimentally for that purpose. Digenic Acid,Kainate,Acid, Digenic,Acid, Kainic

D003342 Corpus Striatum Striped GRAY MATTER and WHITE MATTER consisting of the NEOSTRIATUM and paleostriatum (GLOBUS PALLIDUS). It is located in front of and lateral to the THALAMUS in each cerebral hemisphere. The gray substance is made up of the CAUDATE NUCLEUS and the lentiform nucleus (the latter consisting of the GLOBUS PALLIDUS and PUTAMEN). The WHITE MATTER is the INTERNAL CAPSULE.
