Antigen-induced bronchial anaphylaxis in actively sensitized guinea-pigs: anti-anaphylactic effects of sodium cromoglycate and aminophylline. 1980

P Andersson

1 The inhibitory effects of sodium cromoglycate (SCG) and aminophylline on antigen-induced bronchial anaphylaxis in guinea-pigs, actively sensitized according to different regimens, were examined. 2 SCG (1 mg/kg administered intravenously) reduced the anaphylactic response in animals sensitized with 1 microgram ovalbumin (OA) together with A1(OH)3 100 mg, and challenged at 14 and 40 days after sensitization. If higher doses of antigen (10 micrograms OA together with A1(OH)3 or 5 mg OA on day 0 plus 10 mg OA on day 2) were used for sensitization, the protective effect of SCG was found only in animals tested 14 days after sensitization. 3 A low dose of aminophylline (0.3 mg/kg) that was without a direct bronchodilator effect when tested against a histamine (4 micrograms/kg)-induced bronchospasm, produced an anti-anaphylactic effect. The anti-anaphylactic effect of aminophylline varied slightly with the way the animals were immunized and the time at which they were tested. 4 It is concluded that bronchial anaphylaxis in guinea-pigs sensitized with low doses of ovalbumin is a suitable model for the evaluation of anti-anaphylactic properties of drugs.

D000628	Aminophylline	A drug combination that contains THEOPHYLLINE and ethylenediamine. It is more soluble in water than theophylline but has similar pharmacologic actions. It's most common use is in bronchial asthma, but it has been investigated for several other applications.
