Conventionally prepared immune serum globulin frequently produces severe side effects when administered intravenously. A modified preparation in which 4 to 5 interchain disulfide bonds have been reduced and alkylated has been made for intravenous use. However, reduction and alkylation may affect Fc-mediated functions of immunoglobulin G, particularly its ability to fix complement by the classic...

We report a case of fatal necrotizing pneumonia and sepsis caused by community-associated methicillin-resistant Staphylococcus aureus (CA-MRSA) in an otherwise well, 48-year-old Canadian man with type 2 diabetes mellitus who had travelled to Texas. Despite therapy that included intravenous antibiotics, intravenous immune globulin and other supportive measures, the patient succumbed to his illne...

Three commercial latex kits, IBL, MYCO-Immune, and IMMY, for the detection of cryptococcal antigen were compared in regard to sensitivity, specificity, and height of antigen titers. A total of 218 cerebrospinal fluid and 79 serum specimens from 239 patients were included. Twenty-two patients had culture-proven disseminated cryptococcosis. Both the IBL and MYCO-Immune kits had sensitivities of 1...

The cleavage into large fragments of both normal and immune rabbit y-globulin by cysteine-activated papain was reported by Porter (1, 2). In the case of immune y-globulin the antibody activity was found associated with two of the three principal fragments isolated. Nisonoff et al. (3) have carried out the cleavage of rabbit immune y-globulin into similar fragments with a sedimentation constant ...
