The Smooth Muscle Reaction in the Serum Treated Earthworm

[摘要] The rôle of the smooth muscle in anaphylaxis has been thus summarized by Kolmer (1).The single prominent feature of anaphylaxis in all the species of animals is the effect upon the unstriated muscle. The lesions and symptoms in animals of different species are readily explained upon differences in the distribution of involuntary muscle. The exciting substance … produces immediate and transitory or protracted effects due to contraction which may be followed by relaxation. Such structural changes in the cells of various organs as have been described are readily explainable on the basis of vascular occlusion or dilitation with transudation.In order to test the universality of the smooth muscle reaction as a manifestation of sensitization, the body-wall and the crop of the earthworm as smooth muscle preparations, as described by Straub (2) and Mines (3), were employed in this study.
