The survival of (51)Cr-labeled erythrocytes has been studied in F(1) hybrid mice in which wasting disease was produced by injection of parental lymphoid cells taken either from lymph nodes and thymus or from the spleen. Coincident with the development of the disease syndrome, there occurred a severe anemia accompanied by a sudden loss of circulating labeled erythrocytes, whether host or parenta...

2 biologic and 7 immunologic pregnancy tests were evaluted on the basis of results obtained over a 10-year period. The test evaluated were the Friedman test, the rat ovarian hyperemic test, the urinary chorionic gonadotropin test, the Pregnosticon tube test, the Gravindex slide test, the Pregslide test, the HCG test and the Pregnosticon slide test. The biologic tests were found to be superior ...

Identification, characterization, and purification of allergens are essential for the structural and immunologic studies needed to understand how these molecules induce specific IgE antibody production by the human immune system. Advances in molecular biology techniques have led to the production of recombinant allergens having constant properties, allowing detection of specific IgE directed ag...

We have demonstrated that allograft immunity is impaired in leprosy patients, especially patients with lepromatous leprosy ( 4). This finding indicates that the lymphocytes of leprosy patients are immunologically defective with respect to their activities in vivo, a concept which is supported by the in vitro work of others on lymphocyte transformation (2, 3, 8), and our recent work on lymphotox...

Plasmoacanthoma is an extremely rare verrucous tumor located on periorificial regions characterized by dense dermal plasmacytic infiltrates. Some authors classify it as a form of reactive plasma cell proliferation which represents a heterogeneous spectrum of mucocutaneous disorders. These plasma cell proliferations have been considered to be a benign immunologic inflammatory reaction to known o...

Gluten-related disorders include celiac disease (CD), wheat allergy, and nonceliac gluten sensitivity. CD is an autoimmune enteropathy caused by damage to small intestinal mucosa when gluten is ingested in genetically susceptible individuals. Currently, the only available treatment of CD is gluten-free diet. Several potential treatments are being researched. Wheat allergy is a hypersensitivity ...
