1. We have correlated measurements of colloid osmotic pressure with protein concentrations and albumin/globulin ratios. Plasma from normal rats of different genetic strains was used. 2. The Landis and Pappenheimer equation does not accurately predict colloid osmotic pressure properties of the normal rat plasma used, which had an albumin/globulin ratio of 0.74. Over the range 2-2-12-2 g of prote...

One of us (LWS) bad occasion to treat a young white man with gamma globulin for prophylaxis after exposure to infectious hepatitis. He was given two injections, 10 cc. each, of human Poliomyelitis Immune Globulin, one week apart. It was observed that shortly after the second injection, his severe pustular and indurated acne improved considerably. This observation led to the present study, of wh...

S-sulfonated gamma globulin (GGS), newly developed as a safe drug for intravenous use, was studied for its protective effects against some experimental infections in mice. Gamma globulin showed a good protective activity against infections due to Streptococcus pneumoniae and Escherichia coli and was moderately active against infections due to Staphylococcus aureus and Pseudomonas aeruginosa. In...

1863 liter three years before admission. Instead of providing immediate immune globulin replacement on admission, his clinicians remeasured the serum IgG five days later (130 mg per deciliter), and immune globulin replacement was given seven days after admission. The patient died on the 12th hospital day. There is an extensive body of literature supporting the value of intravenous immune globul...

The globulin content of the standard solution in the vials is standardized either by a Kjeldahl or a biuret determination. When available Lederle (gamma) globulin diluted 1:200 can be used for this purpose as well. The diluted Lederle standard globulin coagulates on heating and so cannot be used as a sterilized standard. An interesting phenomenon was observed while preparing the sterilized wate...

Ferritin- and fluorescein-conjugated antibody staining has been applied to a study of a mouse plasma cell tumor. The presence of myeloma globulin within cisternae of the endoplasmic reticulum was observed at a stage of the secretory process when the remainder of the cytoplasm was essentially free of labeled globulin. The distribution of ferritin suggested a functional heterogeneity among units ...

To identify the genetic causality of migraine and acute, severe melalgia, we performed a linkage analysis and exome sequencing in a family with four affected individuals. We identified a variant (R21L) in exon 2 of the GC globulin gene, which is involved in the transportation of vitamin D metabolites and acts as a chemotaxic factor; this variant was co-segregated within the family. To investiga...

Many sera from normal individuals as well as patients with various disease states contain agglutinating antibodies which show specificity for antigenic determinants of gamma-globulin revealed by pepsin digestion at pH 4.1. Sera containing such agglutinating activity as well as sera negative for these agglutinators contain low molecular weight (3S-5S) components of slow gamma-mobility which inhi...

Aleutian disease-affected mink, which are markedly hypergammaglobulinemic, show a decreased half-life of the serum gamma globulin indicating that the hyperglobulinemia is due to increased production. No evidence that the gamma globulin was antibody to the infectious agent, to autologous or isologous tissues, or to antigens the animal was responding to prior to development of the disease was obt...

ELEVATION of the y-globulin concentration in cerebrospinal fluid (CSF) of patients with multiple sclerosis (MS) and other neurologic disorders has been reported (1-3). Expression of the y-globulin values in milligrams per hundred milliliters does not reveal whether this increase is due to a general elevation of total protein or y-globuin alone. Determinations of both y-globulin and total protei...
