Responses to prepartum injection of sows with Se and vitamin E (E) were evaluated by determining immunoglobulin (IgA, IgM, IgG) levels in the colostrum and serum of the sows and the serum of their offspring. Fifty-four sows (40 multiparous, 14 primiparous) receiving diets adequate in E and Se according to current NRC (1988) standards were randomly allotted to four treatment groups in which a si...

This study evaluated serum protein fractions, HDL-cholesterol, total immunoglobulin G and total immunoglobulin E levels in patients with acute and chronic paracoccidioidomycosis, by means of electrophoresis, enzymatic reaction and immunoenzymatic assay. The results demonstrated elevated levels of total immunoglobulin G, total immunoglobulin E, alpha-2 and gamma-globulins, which were more eviden...

identification of acid-fast bacilli (afb) in sputum or tissue samples is among definite diagnostic methods of tuberculosis. however, this method of diagnosis is restricted by certain limitations.   serologic diagnosis of tuberculosis (tb) has been used for a long time. the aim of this study was to determine the sensitivity and , specificity of antigen 60 (a60) igg, iga, igm test results in tb d...

letrozole is a synthetic aromatase inhibitor and interfere in the committed step in the synthesis of endogenous estrogens from androgens. also estrogens regulate the immune system in teleost. changes of 17- β- esrtradiol (e 2 ), serum immunoglobulin and lysozyme levels were measured using a method based on the ability of lysozyme to lyse the bacterium micrococcus lysodeikticus , enzyme-linked i...

Childhood leukemia, particularly acute lymphoblastic leukemia (ALL), has long been hypothesized to be affected by abnormal immune responses to microbial challenges stemming from a lack of immune modulation in early childhood. Studies of allergies suggest that a child's immune development may be modulated by maternal immune status. We conducted a study to explore the relationship between materna...

Coca and Grove (1925) concluded that serum factors, which they called reagins, were present in individuals with allergic respiratory disease. More than 40 years later, reaginic antibody was shown by Johansson and Ichizaka to belong to the immunoglobin E (IgE) class of immunoglobins. It has been established that the Fc component of IgE has an affinity for surface receptors on mast cells and baso...
