A technique for detecting IgM rubella antibodies by immunofluorescence was developed. Total serum IgG was removed by prior immunoabsorption with anti- γFc. This prevents interference by rheumatoid factors in the serum. The test appeared sensitive and specific in sera of rubella convalescents and infants with congenital rubella. [ABSTRACT FROM AUTHOR]

Presents a study which described the use of both gel diffusion and counterimmunoelectrophoretic methods for the detection of teichoic acid antibodies in parenteral drug users with staphylococcal endocarditis and showed that the counterimmunoeletrophoretic method is of diagnostic value early in the disease. Background on staphylococcal infections; Materials and methods used; Results of the study.

Extensive septal lesions produced a persistent (76 days) reduction in rearing behavior which was not directly attributable to altered deprivation states, emotionality, activity levels, or competing behaviors and which occurred in familiar as well as various novel testing environments. Changes in visual, olfactory, or conspecific stimuli ameliorated or had no effect on the lesion effect. The results indicate that the septal area is importantly involved in normal rearing behavior and that lesion-induced alterations in responsiveness to some forms of stimulation may play a modulatory role in reduced rearing. It is also suggested that the septal area may constitute a portion of a neural system responsible for the initiation of this form of response.
