While the biotransformation of methyl n-butyl ketone (MnBK) in animals is well characterized, little is known about the quantitative relationship between hepatic and plasma MnBK concentrations. This study provides such information and emphasizes the usefulness of MnBK metabolite quantification, as
The effects of exposure to the plasticizer di-(2-ethyl-hexyl)phthalate (DEHP) and its two primary products of presystemic de-esterification, mono-(2-ethylhexyl)phthalate and 2-ethyl-hexanol, on hepatic microsomal oxidation were investigated in rats. The metabolic clearance of antipyrine was utilized
The development of an automated, rapid and highly precise method for determination of the peroxide value in edible oils based on a continuous flow system and Fourier transform infrared (FTIR) spectroscopic detection is described. The sample stream was mixed with a solvent mixture consisting of 25%
Quantitative relationships between plasma, liver and lung methyl isobutyl ketone (MiBK) and methyl n-butyl ketone (MnBK) concentrations after oral or inhalation exposure were established. Their respective metabolites (4-methyl-2-pentanol, 4-hydroxy-methyl isobutyl ketone, 2-hexanol, and
The influence of physicochemical conditions on the phospholipase D (PLD) activity of subcellular preparations of sweet corn (Zea mays L. cv. Peaches and Cream) kernels has been studied. The microsomal, mitochondrial, and cytosolic preparations of corn kernels possessed PLD activity albeit at varying
Sucrose synthase was purified from 22-day-old maize (Zea mays L.) kernels to homogeneity by the successive steps of ammonium sulfate fractionation, gel filtration through a Sephadex G-200 column, and affinity chromatography on a UDP-hexanol-amino-agarose column. The degree of purification is 42-fold
MnBK and MiBK prolong the duration of ketamine-, pentobarbital-, thiopental- and ethanol-induced loss of righting reflex (LRR) in mice. In equimolar doses, (5 mmol/kg i.p.), both isomers were equipotent with respect to the enhancement of ketamine-, pentobarbital-, and thiopental-induced LRR.
