Value of Monitoring Serum Immunoglobulins Questioned Our journal club's review of the recent article by Szczeklik al. (EHP 102:302304) found fault on many levels, especially with the concluding recommendation. It would be neither practical nor useful for workers exposed chronically to PAHs to have serum immunoglobulin levels monitored regularly. The use of cross-sectional data regarding serum i...

background: infertility is one of the common problems seen in couples of reproductive age. presence of antisperm antibodies in semen and serum are amongst the causes of immunoinfertility. this study was performed to determine antisperm antibodies in cervicovaginal secretions and serum of infertile women and also measure serum levels of immunoglobulins (igg, igm and iga). methods: the study cons...

The susceptibility of exocrine and serum immunoglobulins and antibodies to proteolytic degradation was assessed. Colostral and duodenal fluid exocrine 11S IgA, monomeric serum IgA, and IgG were digested with trypsin, chymotrypsin, or duodenal fluid. Exocrine IgA was more resistant to digestion than were the serum immunoglobulins. Under conditions of the experiments, most of colostral IgA retain...

A new class of immunoglobulin, IgD, was identified in normal human serum by immunochemical technics. Antiserums prepared against the unique S.J. myeloma protein facilitated recognition of the related normal protein. IgD was shown to possess type K (I) and type L (II) light chain determinants, similar to those present in other classes of immunoglobulins. IgD does not possess determinants which a...

The paper studies indices of lipid metabolism, immunoglobulins in blood serum heifers different breeds. Black-and-white, Simmental, Aberdeen-Angus, mongrel cattle was selected for this study. Each breed the group consisted 10 heads. study lipids dynamics experimental showed, concentration gradually increased and by 5th month reached maximum values. By end pregnancy on 9th month, a decrease all ...

Forty blood samples were obtame(1 from 36 subjects who ranged ill age from 3 days to 43 years. All subjects were examined! on tile day blood was drawn; the health of each was noted. Each serum sample was analyzed for immunoglobulins y G, y A, aIld y M by the agar gel precipitation method described by Claman and Merrill (2). In this test, serum is layered over a column of agar containing an anti...

The importance of colostrum for the growth and health of newborn offspring is well known. In bovine colostrum, the antibody (immunoglobulin) complement system provides a major antimicrobial effect against a wide range of microbes and confers passive immunity until the calf's own immune system has matured. Bovine serum and lacteal secretions contain three major classes of immunoglobulins: IgG, I...
