摘要
The formation of calcareous corpuscles in the common cat tapeworm, Taenia taeniaeformis, is described. The corpuscle forms in a cytoplasmic cavity, and the corpuscle-forming cell appears to expend itself in the production of one corpuscle. Two corpuscular components were recognized: a homogeneous matrix that may correspond to one of the organic moieties known to be present in corpuscles, and a granular substance that may represent inorganic material. The corpuscle enlarges by the accretion of these two components in concentric layers with progressive compression of the surrounding cytoplasm. © 1969.
