Abstract

The successful management of anaphylaxis requires a thorough understanding of this syndrome and the application of various therapeutic agents. Although the mechanisms responsible for human anaphylaxis are not fully known, sufficient data and clinical experience are available to guide the anesthesiologist faced with this medical emergency.

Quantitative analysis of corticosteroids in adrenal cell cultures by capillary column gas chromatography combined with mass spectrometry.

A quantitative method using glass capillary column gas-liquid chromatography (GLC) has been established for the analysis of corticosteroids in small biological samples such as a few milliliters of medium from steroidogenic cultured cells. The steroid extract is separated in three main thin-layer chromatographic fractions. The steroids assayed in these fractions are: less polar fraction (C21O2) steroids), 20 alpha-dihydroprogesterone, pregnenolone and 20 alpha-dihydro-pregnenolone; intermediate fraction (C21O3 steroids), deoxycorticosterone, 11-oxo- and several hydroxy-20 alpha-dihydroprogesterones; corticosteroid fraction (C21O4 steroids), corticosterone and 18-hydroxydeoxycorticosterone. The method has been assessed by characterizing the steroid structures and checking the purity of GLC effluents through direct coupling of the capillary column to the electron-impact or chemical-ionization source of a computerized mass spectrometer. Applications to the quantitative evaluation of the endocrinological status of newborn rat adrenocortical cell cultures under various conditions of development, hormonal stimulation or specific inhibition by drugs are described.
