Cutaneous Basophil Hypersensitivity Reaction to Phytohemagglutinin in Haifers and Cows with Different Reproductive Results
We investigated the general immune reactivity, as estimated by the zutaneous basophile hypersensitivity reaction (CBHR) to phytohemagglutinin HA) in cows with different reproductive results. The hypersensitivity test was rerformed on the day of artificial insemination and animals were divided into :oups according to the total number of inseminations, number of inseminations :er calving, number ...
متن کاملCutaneous Basophil Hypersensitivity
Delayed onset erythematous skin reactions elicited in guinea pigs early in the course of sensitization with azobenzenearsonate-protein conjugates or with protein antigens in incomplete Freund's adjuvant or in saline were found to have a characteristic morphology which sets them apart from delayed hypersensitivity and the classic antibody mediated reactions. The principle feature was massive der...
متن کاملOcular findings in systemic cutaneous basophil hypersensitivity.
SCBH was induced by immunizing guinea pigs with a protein antigen and challenging 1 week later with a large intraperitoneal dose of the same antigen. Animals developed a delayed-onset, erythematous skin rash and dermal infiltration by basophils and eosinophils. The uveal tracts of these animals were infiltrated by eosinophils, as were several other internal organs. The eye is affected in SCBH, ...
متن کاملGenetic control of cutaneous basophil hypersensitivity
CBH to DNP-GL could be elicited only in responder guinea pigs which possess the genetic ability to develop classic delayed type hypersensitivity to DNP-PLL, the response to which is governed by the same gene. Since the defect in nonresponder animals seems to reside at the level of their T cells and not B cells, these results lend support to the contention that CBH, as well as DH, is dependent o...
متن کاملCutaneous Basophil Hypersensitivity in Contact-sensitized Guinea Pigs
Cutaneous basophil hypersensitivity, an immune inflammatory reaction characterized by infiltrates of basophils and a delayed time-course, was studied in guinea pigs contact sensitized with oxazolone. Routine histological techniques, employing ordinary paraffin sections, were modified to study this reaction. When biopsies of contact lesions were processed by these methods dense infiltrates of ba...
