Gas-liquid chromatographic profile of neutral and acidic metabolites in cerebrospinal fluid from newborns and infants.

چکیده
A profile (chromatographic pattern) of the neutral and acidic metabolites present in cerebrospinal fluid from newborns and infants was obtained by gas-liquid chromatography. The metabolites are those extracted with ethyl acetate and diethyl ether. They are converted to trimethylsilyl ether derivatives, and chromatographed on a column containing 5% silicone OV-101 (methyl) packed on Chromosorb W. Several substances were tentatively identified from their methylene unit values. We established a control profile for infants, and compared profiles for infants and adults. Noteworthy qualitative and quantitative differences from the control were seen for cerebrospinal fluid from subjects with neurological disorders of infections. The technique may be of use in neurological diagnosis.

Separation and identification of neutral and acidic metabolites in cerebrospinal fluid.
We describe a method for obtaining profiles of neutral and acidic substances present in human cerebrospinal fluid (CSF) by gas-liquid chromatography. Metabolites extracted with ethyl acetate and ether are converted to methyl ester, trimethylsilyl ether derivatives. With this technique, acidic metabolites of brain amines, and neutral metabolites of dopamine and norepinephrine have been identifie...

A highly reproducible procedure was developed for gas-liquid chromatographic analysis of trimethylsilyl derivatives of normal human cerebrospinal fluid. Fourteen normal human cerebrospinal fluid samples tested with this procedure contained alpha- and beta-glucose as well as isomers of two unidentified sugars. Chromatographic changes in three cases of meningeal inflammation (two cryptococcosis a...
