[Extramembranous glomerulonephritis induced by lithium]. / Glomérulonéphrite extramembraneuse induite par le lithium.

We report the case of a patient who developed a nephrotic syndrome after lithium carbonate therapy. The nephrotic syndrome disappeared after withdrawal of therapy and recurred when the patient was rechallenged with the same drug. This seems a convincing argument to believe that lithium was the causal agent. Renal biopsy specimens showed membranous nephropathy, suggesting that immune-complex formation was involved in the reaction to the drug. Membranous nephropathy is an exceptional and benign hazard during lithium therapy, and underlines the need for periodic urinalysis in patients treated with the drug.

Application of Carbowax 20M as an open-tubular liquid phase in analyses of nutritionally important fats and oils.

In the first part, the reasons for the choice of Carbowax 20M-terephthalic acid as a liquid phase are indicated and the technique for preparation of columns is descirbed. The ECL of 14 to 24 carbon fatty acids (branched and positional isomers of unsaturated acids) as well as the accuracy of determination of some fatty acids, are presented. In the second part, examples of chromatograms are given as well as tables concerning the composition of various fats: vegetable oils, depot fats, and fats from organs of monogastric species, polygastric species, and fish.
