Abstract
Microprobe analysis of Araldite embedded sections of hyalin bodies revealed the presence of S, Cl, Ca and in some cases Fe. The results were compared with those obtained from control tissue sections of human heel skin, a thrombus occluded vessel and mineralized spherules in a dental follicle. Microradiographic studies showed that the density of hyalin bodies increased progressively towards the core. Isodensitracing confirmed the laminar configuration of hyalin bodies as seen by EM. The hypothesis that hyalin bodies originate as an epithelial secretion was supported.
