Some effects of muscarinic cholinergic blocking drugs on behavior and the electrocorticogram
(Springer-Verlag, 1964-03)
Results are presented for the effects of drugs with muscarinic cholinergic blocking actions, both central and peripheral (scopolamine and 1-hyoscyamine) and primarily peripheral (methyl atropine and methyl scopolamine), ...
Effect of chloride lons on the reaction of diphenylamine with DNA
(Elsevier, 1965-08)
The sensitivity of the Dische test (diphenylamine) for DNA is reduced by the presence of chloride ions, which cause formation of a new reaction product whose absorption maximum is at lower wavelength, and also a reduction ...
Hydrogenation of testosterone sulfate by the [Delta]4-3-ketosteroid reductase of rat liver microsomes
(Elsevier, 1965-01)
TPNH2 is oxidized in the presence of testosterone or testosterone sulfate and a microsomal preparation from the liver of female rats. In the presence of iorganic phosphate, DPNH2 also acts as a hydrogen donor. Evidence is ...
Protein-carbohydrate interaction : III. Agar gel-diffusion studies on the interaction of concanavalin A, a lectin isolated from jack bean, with polysaccharides
(Elsevier, 1965-08)
Concanavalin A, a protein isolated from the jack bean (Canavalia ensiformis), has previously been shown to form a precipitate with glycogen and yeast mannan, and more recently with dextrans and amylopectin. Double-diffusion ...
Infrared target and background radiometric measurements--concepts units and techniques
(Elsevier, 1963-09)
This report discusses concepts units and techniques for making and describing measurements of radiation from targets and backgrounds.
Effects of trifluoperazine on the central nervous system of the cat
(Elsevier, 1966-01)
The effects of accumulative doses of trifluoperazine (0[middle dot]125-8 mg/kg) on the patellar and linguomandibular reflexes and segmentally evoked monosynaptic and polysynaptic spinal cord potentials were determined in ...
Effects of physostigmine on rat brain acetylcholine, acetylcholinesterase and conditioned pole jumping,
(Elsevier, 1968-03)
The present study was designed to provide evidence that the behavioral effects of physostigmine are related to inhibition of brain acetylcholinesterase (AChE). Adult male Holtzman rats were trained to pole jump to a buzzer ...
Hydrogen ion buffers and enzymatic activity: Myosin B adenosinetriphosphatase
(Elsevier, 1968-10)
The production of hydrogen ions during the hydrolysis of ATP by myosin B and the consequent fall in pH can produce alterations in enzymatic activity directly, or by influencing Ca ion concentrations controlled by metal-chelate ...
Characterization of a mutant human erythrocyte carbonic anhydrase: Carbonic anhydrase IcGuam: The amino acid substitution and carboxylesterase and hydratase activities
(Elsevier, 1966-11)
Evidence is presented which indicates that an arginine residue has substituted for a glycine residue in the abnormal human erythrocyte carbonic anhydrase, CA IcGuam. The ratio of the amount of mutant to normal enzyme ...
