Oligomeric, J-chain-containing immunoglobulins were observed to be transferred selectively from serum into colostrum. These studies suggest that, in the case of the mammary gland secretion, a significant role for extraglandular synthesis of IgA merits consideration. Thus, for example, colostrum may contain antibodies synthesized locally as well as antibodies synthesized in the much larger lymph...

The syndrome of protein-calorie malnutrition is associated with an increased frequency of infections which often precipitate or aggravate the state of malnutrition. The importance and the farreaching implications of the interaction between malnutrition and infections, a predominantly synergistic one, have been stressed by Scrimshaw, Taylor, and Gordon (1959) and more recently by the Joint FAO/W...

Immunoglobulin levels in 47 children (age 13-20 years) with toxoplasmosis were compared with 46 age and sex matched controls. No significant difference was observed in mean serum immunoglobulin (IgG, IgA, IgM) levels between patients and controls but mean IgM levels were significantly (P) higher in children with acute toxoplasma infection. Total proteins were higher in patients while mean album...

Serum levels of immunoglobulin A, G, and M were examined in 99 patients with acute anterior uveitis (AAU). The mean level of serum IgA was raised (p less than 0.001) in AAU patients when compared with healthy control subjects. The levels of serum IgG and IgM were not significantly different from those in the control group. The raised levels of serum IgA were found to occur predominantly in the ...

A new, rapid, discrete sampling and automated bichromatic procedure for the measurement of various soluble antigen-antibody complexes of immunoglobulins is described. The incorporation of polymeric substances and salts into the reaction mixture has greatly increased the sensitivity, shortened the reaction time and decreased the cost of the tests. Statistical analyses of data from this method ha...

Juvenile rheumatoid arthritis (JRA) differs in many aspects from its adult counterpart (Edstrom, 1958); one of the differences is a low incidence of positive sero-reactions for rheumatoid factors (RF) in patients with JRA (Bywaters, Carter, and Scott, 1959; Sievers, Ahvonen, Aho, and Wager, 1963; Ansell, 1966). Although the agglutinating activity of RF was found in different classes of immunogl...

Serum proteins and immunoglobulin (Ig) findings in 119 non-Hodgkin's lymphoma (NHL) patients were analysed. Out of them 96 (81%) patients had B non-Hodgkin lymphoma (B-NHL), and 23 (19%) T-NHL. Indolent type of NHL was more frequent (77 patients, 65%), then aggressive type of NHL (42 patients, 35%). Most patients had normal serum protein concentration, the increased protein concentration was se...
