Arthus type inflammation with rat immunoglobulins.

1971

Etude comparative des proprietes biologiques des anticorps IgM, IgG1 et IgG2 du rat. Les resultats montrent que le pouvoir agglutinant et lytique des anticorps IgM est respectivement 37 et 100 fois superieur a celui des deux classes d'anticorps IgG. Par contre, en ce qui concerne le phenomene d'Arthus, les anticorps IgM sont moins actifs que les anticorps IgG, si les rapports sont exprimes en poids. Si l'on calcule les rapports par nombre de molecules, les anticorps IgM sont aussi, dans ce cas, plus actifs que les IgG.

Contact sensitivity to oxazolone in the chicken: evidence for Arthus type hypersensitivity of the cutaneous reaction.

1992

Cutaneous hypersensitivity reaction can be induced in chickens by skin painting with oxazolone, 33 mg/Kg of body weight (KBW). The B cell contribution to the generation of the cutaneous reaction has been a matter of controversy. In an attempt to characterize this reaction we placed special interest on the possibility that the nature of this reaction could be Arthus type hypersensitivity. From the kinetics study on the cutaneous hypersensitivity after challenge with oxazolonated egg-albumin (EA-OX) it was excluded that the nature of this reaction could be delayed type hypersensitivity. Immune sera transfer experiments demonstrated that the cutaneous reaction was antibody dependent. Serum ant…

In vivo cimetidine immunomodulatory effects on the cutaneous reaction to oxazolone in the chicken.

1997

The effect of the histamine H2-receptor antagonist, cimetidine, on the cutaneous Arthus-like hypersensitivity to oxazolone elicited injecting subcutaneously oxazolone conjugated to egg-albumin (EA-OX) has been examined in the chicken. Cimetidine had opposite effects on the cutaneous reaction to oxazolone in relation to a different immunization schedule. Cimetidine enhanced the cutaneous reaction to oxazolone obtained immunizing chickens with oxazolone dissolved in ethanol (Eth-OX); instead cimetidine inhibited the cutaneous reaction obtained in chickens immunized with oxazolone dissolved in complete Freund adjuvant (CFA-OX). Optimum enhancement of the cutaneous arthus-like reaction to oxazo…
