Inhibition of acute anaphylaxis in the chicken by anti-allergic drugs.
The anti-anaphylactic effects of four potential anti-allergic agents (DSCG: disodium cromoglycate, PRD-92-EA, M&amp;B 22,948 and DECC: diethylcarbamazine citrate) were studied on cardiovascular responses of acute systemic anaphylaxis and chemical mediators of immediate hypersensitivity in chickens. Compounds M&amp;B 22,948, PRD-92-EA, DSCG and DECC all inhibited cardiovascular manifestations of systemic anaphylaxis in domestic fowl. High doses of Compounds PRD-92 EA, M&amp;B 22,948 and DECC also exhibited a nonspecific receptor blocking activity towards exogenously administered chemical mediators of anaphylaxis.
