Determination of the glutathione content of erythrocytes and of the catalytic potency of the blood in rheumatic fever as well as an investigation of the dextrose tolerance curves of persons with this disease did not yield particularly striking results. An investigation of the novel formol-gel reaction of Gate and Papacostas2 in a number of febrile diseases with particular reference to rheumatic fever, however, led to interesting observations. In patients with various febrile diseases it was found that, in general, a parallel was demonstrable between the erythrocyte sedimentation rate and the results of the formol-gel reaction, the incidence of positive gel reactions varying directly with acceleration of the sedimentation rate. In patients with rheumatic carditis, however, negative formol-gel reactions were often observed early in the disease, although at the SN - 0002-9955 M3 - doi: 10.1001/jama.1939.02800230048019 UR - http://dx.doi.org/10.1001/jama.1939.02800230048019 ER -
