The major bile acids of gall bladder bile of Varanus monitor have been separated by thin-layer chromatography and shown to be derivatives of taurine. After alkaline hydrolysis, the free acids were separated by thin-layer and partition chromatography. Identification or characterization of the free acids was facilitated by gas-liquid chromatography and(More)
A comparison of the activity of rabbit liver microsomes fortified with 0.1 mM NADPH to promote 12alpha-hydroxylation over 60 minutes with appropriate sterols provided the following relative order of activities: kalpha-cholestane-3alpha, 7alpha-diol, 100; 7alpha-hydroxy-5alpha-cholestane-3one, 76; 7alpha-hydroxycholest-4-en-3-one, 64;(More)
The angioarchitecture of the pineal organ of the rainbow trout (Salmo gairdneri) was investigated by means of the corrosion-cast preparation method and scanning electron microscopy. Two main arteries (aa. epiphyseales) supply the pineal parenchyma. They emerge from the aa. cerebri anteriores and run in the fissure between the prosencephalon and the(More)
Rabbit liver microsomal preparations fortified with 0.1 mM NADPH effectively promote hydroxylation of [3beta-3H]- or [24-14C]allochenodeoxycholic acid or [5alpha,6alpha-3H2]5alpha-cholestane-3alpha,7alpha-diol to their respective 12alpha-hydroxyl derivatives in yields of about 25 or 65% in 60 min. Minor amounts of other products are formed from the diol.(More)
