Dihydroxybenzoic acid (/9-resorcylic acid) is alleged to be as active as sodium salicylate in rheumatic fever , but it does not affect vascular permeability in the mouse . 3,4-Dihydroxybenzoic acid (protocatechoic acid) is not active in rheumatic fever and is barely effective in inhibiting anaphylactic arthritis in the guinea-pig . When administered subcutaneously it does not reduce vascular permeability in the mouse , but reduces formalin-induced oedema in the mouse-foot . When given intraperitoneally,...
