SYNTHESIS OF KALLIKREINS BY RAT KIDNEY SLICES

Synthesis of xanthine oxidase by rat liver slices in vitro.

The influence of dietary protein on the activity of rat liver xanthine oxidase has been studied by several workers (l-5) and would point to a relationship between the availability of amino acids and the activity of liver xanthine oxidase (2). It has been demonstrated that the loss of liver xanthine oxidase activity in the rat greatly exceeds the loss of liver protein during acute inanition (l),...

Effects of Triamcinolone on Carbohydrate Synthesis by Rat Liver Slices.

That adrenal cortical steroids regulate hepatic gluconeogenesis has been recognized for many years (14); however, the exact point of control has yet to be elucidated. Glucose formation from lactate, pyruvate, or propionate involves COz fixation and equilibration in the dicarboxylic acid shuttle, since reversal of glycolysis from pyruvate to phosphoenolpyruvate does not take place in hepatic cel...

Synthesis of membrane protein in slices of rat cerebral cortex.

Protein synthesis was studied in slices from rat cerebral cortex and localized in various purified subcellular membrane fractions isolated after incubation with L-leucine. A synaptosomal fraction isolated from a several times washed crude mitochondrial pellet showed very little contamination by free membranes, and the synaptic membrane fraction isolated from it was estimated to c +ain about 50%...

The synthesis of nicotinuric acid by rat-kidney preparations.

A Study of the Fluid Uptake of Rat Kidney Slices in Vitro* by Ingrith Deyrup

Observations of Sperry and Brand (1), Elliott (2), Opie (3, 4), and others (5-9) have established the somewhat surprising fact that surviving slices of mammalian liver, brain, kidney, and certain other tissues take up relatively large amounts of fluid from a variety of solutions which are considered to be isosmotic with mammalian interstitial fluids (e.g., homologous serum and various Ringer's ...
