BASE‐EXCHANGE REACTIONS FOR THE SYNTHESIS OF PHOSPHOLIPIDS IN NERVOUS TISSUE: THE INCORPORATION OF SERINE AND ETHANOLAMINE INTO THE PHOSPHOLIPIDS OF ISOLATED BRAIN MICROSOMES 1, 2
Abstract— The calcium‐dependent incorporation of l‐[3‐3H]serine and [1,2‐14C]ethanol‐amine into the phospholipid of isolated subcellular fractions from chick brain was studied and the properties ofExpand
The effect of transient ischemia on fatty acid and lipid metabolism in the gerbil brain.
Brain ischemia was produced in gerbils by contemporary occlusion of both carotid arteries. Definite changes of the energy state in brain demonstrated that carotid occlusion was effective. At shortExpand
The activity of silymarin on mitochondrial swelling in the rat
Summary Silymarin, an antihepatotoxic principle extracted from Silybum Marianum , does not affect the respiratory chain and the P/O ratio of rat liver mitochondria in vitro . The swelling effectExpand
THE EFFECT OF NERVE SECTION ON THE FREE AMINO ACIDS OF NERVOUS TISSUE
THERE exist in the literature a number of reports on the content of various free amino acids in brain tissue, but, apart from the work of LEWIS (1952; 1954) on the free amino acids of invertebrateExpand
The reverse reaction of cholinephosphotransferase in rat brain microsomes. A new pathway for degradation of phosphatidylcholine.
The synthesis of phosphatidylcholine is catalyzed by cholinephosphotransferase (EC 2.7.8.2) which is known to be reversible in liver. The reversibility of cholinephosphotransferase in rat brain inExpand
Effect of cytidine diphosphate choline (CDP-choline) on ischemia-induced alterations of brain lipid in the gerbil
Brain ischemia was produced in gerbils (Meriones unguiculatus) by the bilateral ligation of the carotid arteries. Definite changes in the energy status of brain demonstrated that carotid occlusionExpand

IN a previous study on the levels of free amino acids in nervous tissue (PORCELLATI and THOMPSON, 1957) evidence was obtained of the presence in aqueous alcoholic extracts of these tissues of aExpand
Action of phospholipase A2 of rabbit neuronal and glial cells on 1,2-diacyl-, 2-acyl-1-alk-1′-enyl-, and 2-acyl-1-alkyl-glycerophosphatides
Pronounced differences in the phospholipase A2 activities were found in neurons and glia, the enzyme activity being two- to threefold higher in neurons than in glial cells. Both phospholipases A2Expand
The metabolism of phosphoric esters and of cytidine-diphosphate esters of choline and ethanolamine in the liver
Abstract 1. 1. The labelled phosphate and cyddine-diphosphate esters of choline and ethanol-amine, together with their bases, were incubated with rat liver homogcnate and microsomal membranes, andExpand
