Rats were administered [3H]spiperone (SP: spiroperidol) by tail vein injection and 2 h later the brain was processed for light microscopic autoradiography. High densities of autoradiographic grains were found in all areas known to have a dopaminergic innervation, including the olfactory tubercles, nucleus accumbens, nucleus caudate-putamen, lateral septum,(More)
The phylogenetic distribution of specific binding sites for kainic acid was determined in 14 species including invertebrates and vertebrates. The highest level of binding was observed in brains of the frog (Xenopus laevis), followed by the spiny dogfish (Heterodontus francisci), the goldfish (Carasius auratus) and the chick (Gallus domesticus). Although(More)
The hypocholesterolemic agent 3 beta-(2-diethylaminoethoxy)androst-5-en-17-one . HCl (U18666A) is known to induce experimental epilepsy. The possibility that this drug interferes with cholesteryl ester formation in glioblastoma cells was examined. The incorporation of radioactive oleic acid into cellular cholesteryl ester was drastically and specifically(More)
Two forms of rat brain cytosolic diacylglycerol kinase (EC2.7.1.107) were separated by heparin-agarose column chromatography. These forms, designated DGK-I and DGK-II, were not interconvertible as determined by rechromatography. DGK-I and DGK-II had respective molecular masses of 88 and 180 kDa, as measured by Sepharose 6B chromatography. Both forms(More)
