this study was undertaken to estimate specific activities of rhodanese and 3-mercaptopyruvate sulfurtransferase (mst) in different tissues of turkey. enzyme activities were determined in tissue samples from freshly killed adult male turkeys by measurement of thiocyanate amounts produced by the action of enzymes on suitable substrates. activities of rhodanese and mst in examined tissues of turke...

Distribution of transglutaminase activity was determined in normal rat liver, a 3'-methyl-4-dimethylaminoazobenzene-induced primary hepatoma, and the Novikoff hepatoma. Over 90% of the total enzyme activity was found in the 105,000 X g supernatant of normal liver, whereas only 30% was found in this fraction of the hepatomas, the remainder being found in the particulate fraction. The is distribu...

The 7- to 10-fold increase in the rat liver serine:pyruvate aminotransferase activity after glucagon administration was shown to occur mainly in the mitochondrial matrix of parenchymal cells. The enzyme was purified from glucagon-treated rat liver mitochondria to apparent homogeneity as judged by sodium dodecyl sulfate-polyacrylamide gel electrophoresis. A specific rabbit antibody was prepared ...

The change in glutamine synthetase activity has been studied under two conditions of liver growth, namely, mitotic growth after partial hepatectomy and nonmitotic growth during repletion after a fast. The surgical operation caused the enzyme activity in the liver to diminish to one half its normal value within one week after the operation and to remain at this reduced level for the duration of ...

In this study, the hepatoprotective effect of the methanol extract of aerial parts (shoot) from Otostegia persica Boiss (Golder) was investigated against the carbon tetrachloride (CCl4)-induced acute hepatotoxicity in male rats. Liver damage was induced through the oral administration of 50% CCl4 in liquid paraffin (2.5 mL/Kg bw, per os) 60 min after the administration of the methanol extract o...

An enzyme which synthesizes S-adenosylmethionine in mouse liver has been examined and found to possess the same charac teristics as that described by others for pig and rabbit liver. Al though liver has laige quantities of the enzyme activity, a mouse hej tatoma had no measurable activity. It was hypothesized that trace amounts of the enzyme in hepatoma cells might be sufficient for sRNA methyl...

1. In the presence of CoA and ATP, human liver microsomes catalyse the incorporation of [14C]oleate or [14C]cholesterol into cholesteryl oleate, thus demonstrating the presence of acyl-coenzyme A-cholesterol acyltransferase (cholesterol acyltransferase) in human liver. 2. The enzyme has properties similar to those of rat liver enzyme and with both the concentration of endogenous cholesterol in ...
