Direct determination of selected metals in refractory powder micro samples with exploding thin film excitation
(Elsevier, 1980)
The direct determination of metallic elements in powder micro samples is explored. Emphasis is placed on refractory materials prepared as alcoholic suspensions of their powders. Silver thin films are vacuum deposited on ...
Sensitive gas chromatographic assay for the quantitation of bretylium in plasma, urine and myocardial tissue
(Elsevier, 1980-01-11)
A sensitive analytical method has been developed for the quantitation of bretylium in plasma, urine and myocardial tissue. Bretylium and the internal standard, UM-360 (o-iodobenzyltrimethylammonium), are extracted and ...
The effect of dietary supplementation of fish oil on experimental myocardial infarction
(Elsevier, 1980-12)
The effect of altering the abundance of precursors and inhibitors of prostaglandin formation by dietary supplements of fish oil was investigated in dogs with experimentally induced myocardial infarction. Prior to induction, ...
Interaction of opiate peptide and noradrenalin systems: Light microscopic studies
(Elsevier, 1980)
In this light microscopic immunocyto-chemical study [beta]-Endorphin ([beta]-END), leu-enkephalin and dopamine-[beta]hydroxylase (DBH) antisera are used to obtain an overview of the interaction of the noradrenergic and ...
Hydroxylation and expoxidation reactions catalyzed by synthetic metalloporphyrinates. Models related to the active oxygen species of cytochrome P-450
(Elsevier, 1980-02)
Iodosylbenzene has been found to react with catalytic amounts of synthetic metalloporphyrinates to give epoxides and alcohols from olefins and alkanes. Tetraphenylporphinatoiron(III) chloride (TPPFeCl) catalyzed the ...
Behavior maintained by intravenous injection of codeine, cocaine, and etorphine in the rhesus macaque and the pigtail macaque
(Springer-Verlag, 1980-10)
Lever-pressing behavior of two species of macaque, the rhesus macaque ( M. mulatta ) and the pigtail macaque ( M. nemestrina ) was maintained by intravenous injection of codeine, etorphine, or cocaine. Monkeys responded ...
Effects of an ACTH 4-9 related peptide upon intracranial self stimulation and general activity in the rat
(Springer-Verlag, 1980-11)
Adult male Sprague-Dawley rats were stereotactically implanted with electrodes within the anterior medial forebrain bundle: The rats were trained to respond for intracranial self-stimulation (ICS) and treated with control ...
Separation of urinary catecholamines and catecholamine metabolites by high-pressure liquid chromatography
(Elsevier, 1980-06)
A series of high-pressure liquid chromatographic (hplc) procedures are described for the separation of all major and most minor catecholamine metabolites present in human urine. The amines and metabolites are first ...
Effect of pH on metabolism of the glutamine carbon skeleton by renal cortical mitochondria
(Elsevier, 1980)
1. 1. To determine the effect of altered acid-base homeostasis on the intramitochondrial metabolism of the glutamine carbon skeleton 14CO2 production from [U-14C]glutamine by isolated rat renal cortical mitochondria was ...
Potentiation of L-DOPA induced motor activity by an inhibitor of phenylethanolamine-N-methyltransferase
(Elsevier, 1980)
1. 1. Pharmacological inhibition of phenylethanolamine-N-methyltransferase (PNMT), the synthesizing enzyme for adrenaline, resulted in enhanced behavioral activation by 3,4,-dihydroxyphenylalanine (L-DOPA) in mice.2. 2. ...
