Macrophage migration technique using coccidioidin.
نویسندگان
چکیده
Guinea pigs sensitized by repeated skin testing with potent, merthiolated coccidioidin, equal to Smith standard, exhibited erythema, edema, and an induration-like reaction to intradermal injection of the preparation. No statistically significant migration inhibition of peritoneal exudate macrophages from these animals was observed.

Comparison of coccidioidin and spherulin in complement fixation tests for coccidioidomycosis.
Coccidioidin, an extract from the saprophytic mycelial form of Coccidioides immitis, has been a very useful antigen preparation in serological tests for coccidioidomycosis. Its sensitivity has been very good for detecting most types of clinical disease, but tests with coccidioidin have been negative for 40% or more of patients with chronic pulmonary disease, the clinical entity which must be di...
متن کاملAntigenic identity of biologically active antigens in coccidioidin and spherulin.
We recently reported the isolation of three clinically relevant antigens from coccidioidin; viz., the antigen that is reactive in the immunodiffusion (ID) assay for detecting tube precipitin (TP) antibody (designated IDTP); the antigen that is reactive in the ID assay for detecting complement-fixing antibody (designated IDCF); and the heat-stable (HS) antigen which, when demonstrated in soluble...

1. The literature concerning inhalation infection with Coccidioides immitis is briefly reviewed. 2. A laboratory technique for exposing animals to inhalation of the spores of Coccidioides immitis is described. 3. Primary pulmonary infection was produced in 42 per cent of 72 animals exposed by this method. 4. No marked weight loss was apparent in the animals infected. 5. Skin tests with coccidio...
متن کاملO-28: Endometriosis Is Influenced by The Promoter Haplotype-Based Expression of Macrophage Migration Inhibitory Factor (MIF)
Background: Macrophage migration inhibitory factor (MIF) is a key pro-inflammatory cytokine that is secreted by accumulated active macrophages in ectopic tissue of endometriosis. MIF is involved in pathophysiological events of endometriosis, such as angiogenesis and cell proliferation. MIF that stimulates the synthesis of PGE2, leads to over-expression of local estradiol synthesis in endometrio...
