Abstract

1. Sera of 22 children with cow's milk clinical hypersensitivity were studied to demonstrate the presence of substances immunologically related with milk. They were compared with 23 controls. The infants of both groups were feed with bovine milk. The immunogenic capacity of cow's milk and their major proteins were experimentally investigated. 2. Specific rabbit antisera were obtained by injection of antigens with incomplete Freund adjuvant. Double difussion gel, passive hemagglutination and ultramicromethod for the determination of antigen antibody precipitated were performed. 3. Immunogenicity was proved by precipitation and hemagglutination methods. by precipitation cow's milk antigens were present in 5 of 22 sera of antigenic patients, in 3 of them ALA antigens were present and in only 1 of them, caseina were present. By hemagglutination, 12 of 22 allergic infants showed ALA and BLG and 11 caseine (C). In 2 of 7 controls, beta lactoglobuline (BLG) was present and in an other one C. It was possible to detect incomplete antigens related with ALA, BLG, and C in allergic infants as well as controls. A significative difference was found for BLG (P less than 0.01) and it was highest (P less than 0.003) in infants with protein calo...Continue Reading

Allergy and Asthma

Allergy and asthma are inflammatory disorders that are triggered by the activation of an allergen-specific regulatory t cell. These t cells become activated when allergens are recognized by allergen-presenting cells. Here is the latest research on allergy and asthma.

Atopic Dermatitis

Atopic dermatitis is a chronic inflammatory genetically determined disease of the skin marked by increased ability to form reagin (IgE), with increased susceptibility to allergic rhinitis and asthma, and hereditary disposition to a lowered threshold for pruritus.
