In human serum there are two protein fractions that are potent inhibitors to trypsin. These inhibitors travel with the a1-globulin and a2-globulin fractions when serum proteins are separated by electrophoresis (1-3). One ml of normal serum has sufficient amounts of trypsin inhibitor to neutralize the proteolytic effect of 1.15 (± 0.10) mg of crystalline trypsin. Approximately 90 per cent of the...

It has been proposed that inflammation or infection may contribute to the development of type 2 diabetes. We examined whether serum gamma globulin, a nonspecific measure of the humoral immune system, predicted changes in glucose tolerance in 2,530 members of the Pima Indian population, a group with a marked predisposition to type 2 diabetes. Cross-sectionally, gamma globulin was positively rela...

(Y 2u Globulin is a protein synthesized in the liver, secreted into the serum, and excreted in the urine of mature male rats. The effects of androgens and estrogens on the level of the messenger RNA coding for this male rat hepatic protein have been investigated. Castrated male rats have reduced levels of (Y 2u globulin in serum and liver cytosol, as measured by a radial immunodiffusion assay. ...

We performed a randomized, controlled trial of intravenous immune globulin (respiratory syncytial virus [RSV] neutralizing [Nt] antibody titer of 1:950 in 5% solution) to evaluate protection against RSV-induced disease over two respiratory virus seasons. Forty-nine children (mean age at enrollment, 4.5 months) with severe congenital heart disease or bronchopulmonary dysplasia were randomized as...

Cells from leukemia L1210 and a subline resistant to methylglyoxal-bis(guanylhydrazone) elicited a demonstrable humoral antibody response in DBA/2Ha-DD mice. Using paired-label 7-globulin mixtures containing '3 ' I-labeled normal and '2 5I-labeled immune 7-globulin, we showed that the specific uptake of antiresistant L1210 cell 7-globulin by resistant L1210 cells was consistently higher than th...

Synovial fluid plays an important role in lubricating synovial joints. Its main constituents are hyaluronic acid (HA) and γ-globulin, acting as boundary lubricants for articular cartilage. The aim of the study was to demonstrate the concentration-dependent effect of HA and γ-globulin on the boundary-lubricating ability of human osteoarthritis (OA) cartilage. Normal, early and advance stage arti...

The fractional rates of catabolism of isotopically labeled mouse, human, bovine, and guinea pig gamma-globulins and human serum albumin were determined in mice and in guinea pigs whose serum gamma-globulin and serum albumin levels were elevated by immunization or by injections of exogenous serum proteins. These serum proteins were also followed in mice with different serum gamma-globulin levels...

To further evaluate thyroid function in patients with liver disease, we have measured total and free T3 and T4, thyroxine binding globulin, basal and thyrotropin releasing hormone-stimulated thyrotropin and thyroglobulin antibodies in 33 patients with liver cirrhosis, in 22 with chronic hepatitis and in 30 healthy controls. All the patients but one were clinically euthyroid. T3, FT3, T3/thyroxi...

Six human hematopoetic cell lines were successfully heterotransplanted into athymic (nude) and asplenic-athymic (Iasat) neonatal mice. The tumors arising from leukemia and lymphoma cells could then be serially transplanted into adult nude mice. Seven days after the fourth serial mouse passage, each mouse was treated with goat immune gamma globulin against K-562 cells. One control group was trea...

The approximate association constants of the plasma vitamin D binding globulin (Gc-globulin) for 25-hydroxycholecalciferol (25(OH)D3) and the plasma 25(OH)D3 binding capacities were measured in samples from 123 patients with a variety of disorders. No gross differences in binding affinities were observed between different groups of patients and controls. Many patients, however, had moderately r...
