Ventricular CSF glucose, total protein, protein electrophoresis, IgG, IgA, IgM and CSF cytology were determined in thirty seven patients with brain tumours. CSF glucose was unchanged and total protein was significantly high. Protein electrophoresis showed higher albumin and gamma globulin fractions. Mean IgG and IgA were significantly higher (P less than 0.001) in malignant tumours than in beni...

Bound gamma globulin was demonstrated by the direct immunofluorescent technique in heart tissue from three patients with severe congestive cardiomyopathy. In two of these patients complement (,81C) was also bound to the heart muscle. Heart tissue from one of six patients who died of myocardial infarction showed a trace of bound gamma globulin, but no bound complement. During life, the heart in ...

Immunologic tolerance to ultracentrifuged bovine gamma globulin could not be induced in 6-wk old NZB or B/W mice, but developed readily in C3H, NZW, and C57Bl mice. NZB and B/W mice, as well as Balb/c mice, failed to become tolerant to ultracentrifuged human gamma globulin. The NZB and B/W mice also showed higher antibody titers to a standard antigenic challenge. This immunologic hyperreactivit...

Endotoxin was demonstrated not to act as an adjuvant in the primary antibody response in the Syrian hamster. Minimal adjuvant action was demonstrable in antibody formation to a second injection of bovine gamma globulin. The immunological status of the hamster towards the endotoxin did not alter this weak adjuvant action. It was confirmed that the antimitotic drug colchicine will act as an adjuv...

A wide assortment of antibodies has been analysed by qualitative and quantitative techniques for their content of group I- and group II-type gamma-globulin molecules. These included Rh antibodies, isoagglutinins, thyroglobulin antibodies, dextran antibodies, and teichoic acid antibodies. All the antibodies studied showed the presence of both groups. However, the ratio of the two varied widely i...

In the course of experiments involving centrifugation of fresh postprandial human serum diluted with isotonic sucrose, an unexpected phenomenon was noted; the usual opaque fat layer at the surface was missing, and a white pellet was deposited at the bottom of the tube. Microscopic and chemical examinations revealed the deposit to be composed of chylomicrons. Further study of this phenomenon dem...

The work of Edelman and collaborators'-3 and of other investigators4-6 has demonstrated that 6.5 S gamma globulin molecules of various species consist of several polypeptide chains. Recent experiments of Fleischman, Pain, and Porter7' 8 and of Marler and Tanford9 indicate the presence in rabbit gamma globulin of two chains of molecular weight of 55,000-60,000 each, and two of molecular weight 2...

The electrophoretic patterns of a series of normal and pathological human sera and plasmas have been obtained using the schlieren scanning method. From these patterns the mobilities and concentrations of the electrophoretically distinct protein components have been computed. The mobilities fall into five well defined groups corresponding to albumin, alpha, beta, and gamma globulins, and fibrino...

The turnover of (131)I-labeled gamma globulin has been determined in rabbits before and during (8 weeks later) hyperimmunization with pneumococcic vaccine, which increased the gamma globulin concentration 5 to 10 times. Before immunization fractional turnover rate was an average of 36 per cent of the plasma pool per day, and the rate of catabolism was 133 mg/kg/day. During hyperimmunization fra...

A smallpox vaccination program has been initiated. The vaccine is a live virus that was used in the last century. Postvaccinal encephalitis is a complication of this vaccine. The clinical presentation, course, neuroimaging findings, and spinal fluid abnormalities are similar to a disorder that physicians are familiar with, acute disseminated encephalomyelitis. This complication can be prevented...
