Immunocytochemical localization of delta 3, delta 2-enoyl-CoA isomerase (isomerase) was investigated in rat liver. Livers of di-(2-ethylhexyl)phthalate (DEHP)-treated or untreated rats were perfusion-fixed and embedded in Epon or Lowicryl K4M. By light microscopy, reaction deposits for the enzyme were present in the cytoplasmic granules of hepatocytes and(More)
The effect of l-threo-DOPS on the reserpine-induced ptosis in mice and its modification by imipramine, a norepinephrine (NE) uptake inhibitor, or nialamide, a monoamineoxidase inhibitor, were studied. Intraperitoneal (i.p.) injection of l-threo-DOPS (800 mg/kg) significantly reduced the severity of the ptosis. This reversal of the ptosis by l-threo-DOPS was(More)
Administration of p-chlorophenoxyisobutyric acid (clofibric acid) markedly increased the activity of microsomal 1-acylglycerophosphorylcholine (1-acyl-GPC) acyltransferase in kidney, intestinal mucosa and liver, but not in brain, heart, lung, spleen, testis or skeletal muscle. In both kidney and liver, a marked dose-dependent increase in the activities of(More)
Administration of clofibric acid, 2,2'-(decamethylenedithio)diethanol, di(2-ethylhexyl)phthalate or perfluorooctanoic acid to male rates increased markedly microsomal 1-acylglycerophosphocholine (a-acyl-GPC) acyltransferase in a dose-dependent manner in liver. Simultaneous administration of actinomycin D or cycloheximide completely abolished the increase in(More)
Morphological mutants of Micrococcus lysodeikticus (luteus) were isolated by treatment with N-methyl-N'-nitro-N-nitrosoguanidine. They occurred on plates in large, regular cell packets, whereas the parent cells usually grew as groups of two or four cells or as short chains. The mutants required a much higher concentration of Mg2+ for growth than the parent(More)
Localization of 2,4-dienoyl-CoA reductase (DCR) in rat liver was studied using immunoenzyme and immunogold techniques. The animals were fed on a laboratory diet with or without 2% di-(2-ethylhexyl)phthalate (DEHP), a peroxisome proliferator, for two weeks. For light microscopy (LM), semithin Epon sections were stained by immunoenzyme technique after removal(More)
Administration of p-chlorophenoxyisobutyric acid (clofibric acid) to rats induced a marked change in acyl composition of hepatic glycerolipids; a considerable increase in the proportion of octadecenoic acid (18:1) was accompanied by a marked decrease in the proportion of octadecadienoic acid (18:2). Among the glycerolipids, the changes in the proportions of(More)
Electrophysiological studies using spectral analysis techniques were undertaken in rabbits to determine whether or not hippocampal rhythmical slow activity (RSA, theta wave activity) was affected by the 5-hydroxytryptamine1A (5-HT1A) agonists 8-hydroxy-2-(di-n-propylamino) tetralin (8-OH-DPAT) and 3 α, 4 β, 7 β, 7(More)
The subcellular distribution of delta 3,delta 2-enoyl-CoA isomerase [EC 5.3.3.8] and the inducing effect of clofibrate, a peroxisomal proliferator, on the enzyme activity were examined in rat liver. From the results of spectrophotometric investigation of the fractions, which were prepared by sucrose discontinuous gradient centrifugation from the light(More)
The developmental capacity of reconstructed bovine oocytes that contained nuclei from growing stage oocytes, 70-119 microm in diameter, was assessed after fertilization in vitro. Nuclei from growing stage oocytes of adult ovaries were transferred to enucleated, fully grown germinal vesicle (GV) stage oocytes. After culture in vitro, the reconstructed(More)
