...Odutayo O. Odunuga; Gbolahan W. Okunade; Olufunso O. Olorunsogo Sodium arsenite (NaAsO 2 ), at 10% of its median lethal dose, was administered to rats with and without vitamin C pretreatment. Liver microsomal fraction was isolated and the activity of Ca 2+ -ATPase was assayed. Sodium arsenite...

...O. O. Odunuga; G. A. Adenuga The effect of a short-term oral administration of potassium cyanide (KCN) (200 ppm in diet) with or without sodium nitrite (NaNO 2 ) pretreatment on rat brain microsomal Ca 2± ATPase was investigated. The specific activity value of the enzyme significantly decreased (p...

...Gheorghe Benga; William Ferdinand The amino acid composition of proteins from liver microsomes has been studied in rats and in human subjects with normal liver, with obstructive jaundice or liver cirrhosis. The pattern of the amino acid composition of microsomes appeared to be species-specific...

.... Subsequent saturation required 90 min. The half-lives of dolichols in microsomes were between 80 and 118 h, and shorter dolichols had shorter values of T 1/2 . The half-lives of dolichols in lysosomes were between 115 and 137 h, while microsomal dolichyl-P exhibited a T 1/2 of 32 h. Injected dolichol...

... with microsomes, trypsin and detergent treatment of peroxisomes did not influence the rate of cholesterol synthesis. In addition, the luminal content of peroxisomes could alone mediate this synthetic process. Upon treatment of rats with various inducers of peroxisomes and of the endoplasmic reticulum, as well...

...Julie L. Hutson; Joan A. Higgins Rat liver microsomes incorporate [ 14 C]palmitoyl CoA into membrane phospholipids via the deacylation/acylation cycle. This activity is reversibly inactivated/activated by treatment of the microsomes with ATP, MgCl 2 , and 105,000 g supernatant or with 105,000 g...
