Micro method for determination of borohydride with NAD+
(Elsevier, 1973-08)
A spectrophotometric method for the determination of borohydride is described. It involves the reduction of NAD+ to a number of isomeric forms of NADH by borohydride. In the standard assay procedure herewith presented, ...
Short-term effects of marijuana smoking on cognitive behavior in experienced male users
(Springer-Verlag, 1973-03)
The effects of smoking marijuana on the ability to use abstract concepts was tested in 12 experienced marijuana users. Each subject was tested three times, after smoking prepared 300 mg cigarettes containing either 0, 1.5 ...
The enthalpies of combustion and formation of [2.2]-paracyclophane and triptycene
(Elsevier, 1973-09)
The enthalpies of combustion, ΔHoc, for crystalline [2.2]-paracyclophane (C16H16) and triptycene (C20H14) have been measured by oxygen combustion calorimetry. The derived standard enthalpies of formation at 298.15 ...
Effects of morphine, nalorphine and naloxone on neocortical release of acetylcholine in the rat
(Springer-Verlag, 1973-06)
The effects of morphine (10 mg/kg), nalorphine (1 and 10 mg/kg), and naloxone (1 mg/kg) were studied on the neocortical release of acetylcholine (ACh) in midpontine pretrigeminal transected rats. Morphine and, to a lesser ...
Effects of physostigmine on brain acetylcholine content and release
(Elsevier, 1973-01)
The content and release of acetylcholine (ACh) from cat brain and ACh content of rat brain was measured using the frog rectus and leech muscle bioassays before and after physostigmine 100 [mu]g/kgi.v. or i.p. The drug ...
Effects of stress and REM sleep deprivation on the patterns of avoidance learning and brain acetylcholine in the mouse
(Springer-Verlag, 1973-12)
Pure bred DBA/2J mice were subjected to varying degrees of stress and “water tank” REM sleep deprivation using one-animal cages, large platforms and/or poles. Subsequently, the animals were studied for acquisition, short-term ...
Genetic variation in the carbonic anhydrase isozymes of macaque monkeys : III. Biosynthesis of carbonic anhydrases in bone marrow erythroid cells and peripheral blood reticulocytes of Macaco nemestrina
(Elsevier, 1973-09)
The carbonic anhydrase isozymes (CA I and CA II) of the pig-tailed macaque, Macaca nemestrina, have been chosen to study the regulation of enzyme levels in red blood cells. Two quantitative variants of CA I that are ideal ...
