Induced Unresponsiveness to Simple Allergenic Chemicals
Normal guinea pigs fed chemical haptens develop a specific state of unresponsiveness, inhibiting subsequent development of dermal sensitization with the same hapten and modifying profoundly the synthesis of anaphylactic antibody in response to hapten conjugated to guinea pig proteins. The degree of unresponsiveness has been tested by exposing hapten-fed animals to intense haptenic stimulation. ...
متن کاملImmunological Unresponsiveness to Sensitization with Simple Chemical Compounds
Guinea pigs fed picryl chloride to induce specific immunologic unresponsiveness cleared small amounts of venously infused antipicryl antibody at a rate equal to that of normal guinea pigs. Catabolism of passively administered picryl-specific antibody did not alter the unresponsive state of picryl chloride-fed guinea pigs or the responsive state of normal guinea pigs. Lymphoid cells of picryl ch...
متن کاملFlexural Behavior of Polyester Polymer Concrete Subjected to Different Chemicals
Polymer concrete (PC) is a composite material prepared by resin and aggregates. Advantages of polymer concretes include rapid curing at ambient temperatures, high flexural and compressive strengths, excellent chemical resistance and low permeability. In this research, a comparative study was performed on degradation of polyester resin concrete in different chemical solutions. Polymer concrete s...
متن کاملRouting of Physarum polycephalum “signals” using simple chemicals
In previous work the chemotaxis toward simple organic chemicals was assessed. We utilize the knowledge gained from these chemotactic assays to route Physarum polycephalum "signals" at a series of junctions. By applying chemical inputs at a simple T-junction we were able to reproducibly control the path taken by the plasmodium of P. Polycephalum. Where the chemoattractant farnesene was used at o...
متن کاملStudies on the Sensitization of Animals with Simple Chemical Compounds
The fate of (14)C-labeled allergens injected intradermally into guinea pigs, namely picryl chloride (PCl*) and 2:4 dinitrochlorobenzene (DNCB*), was followed during the induction period of delayed hypersensitivity. Both chemicals were applied in a single injection into one ear in amounts that approached their minimal sensitizing doses (PCl, 0.25 microg; DNCB, 5.0 microg). Radioactivity in the v...
