X-ray diffractometric analysis of L-cystine stones in 12 patients.

In 12 of 21 cystinuric patients, the components of cystine stones, either previously passed or removed at surgery, were studied by X-ray diffractometry and chemical analysis. The results of diffractometry suggested that, in addition to cystine, the stones contained sodium urate and ammonium magnesium orthophosphate hydrate, although chemical analysis was negative for these components. The role of uric acid in cystinuria is discussed.

The Gm and Inv factors in rheumatoid arthritis.

The Gm(1), Gm(2), Gm(4), Gm(12), and Inv (1) factors were studied in the sera of 56 patients suffering from rheumatiod arthritis and 26 from various rheumatic diseases, by the hemagglutination inhibition test, using optimally reacting mixtures of Ragg and Nagg sera. The distribution of these factors was found to agree with that of healthy Greeks. No correlation was found between hypergammaglobulinemia and the discovery of the Gm(1) and Inv (1) factors. The presence of the rheumatoid factor was independent of the Gm and Inv phenotypes.
