Studies on the Tissue Reactions to the Paste of Calcium Hydroxide added Iodoform (Root Canal Filling Material: Vitapex^[○!R]) Second report. A electron-microscopic study ヨードホルム・水酸化カルシウムパスタ(糊剤根管充填材ビタペックス)の組織埋入に関する実験的研究 第2報 電子顕微鏡的検索 川上, 敏行 中村, 千仁 林, 俊子 枝, 重夫 赤羽, 章司 application/pdf Using 21 rats the reactions of subcutaneous tissues to calcium hydroxide added idoform (Vitapex^[○!R]: Root canal filling material) were studied by means of electron-micro-scopy. Resalts were as follows: 1. Collagen fibers were gradually formed around the paste. Needle-like calcium crystals were appeared on the collagen fibers. 2. In the area of sparsely distributed collagen fibers and matrix vesicles contained with electron-dense materials, the growth of crystals beyond the calcified matrix vesicles was obserbed. 3. It was suggested that the matrix vesicles came from the regressive changes of cells. 4. The calcium salts, phagocytized within histiocytes, were demonstrated as electron-dense masses. 5. Silicone oil in the paste was also phagocytized by histiocytes, showing the droplets in the cytoplasm. 6. It was considered that histiocytes had the phagocytotic share, because there were no histiocytes containing both calcium hydroxide and silicone oil. 7. Many lysosomes were observed along the phagocytosis. The lysosomes fused with the phagosomes, and then the cytoplasm of histiocytes was occupied by many phagolysosomes. journal article 松本歯科大学学会 1979-12-31 VoR application/pdf 松本歯学 2 5 161 170 AN00232590 0385-1613 https://mdu.repo.nii.ac.jp/record/229/files/matsumoto_shigaku_05-02-05.pdf https://mdu.repo.nii.ac.jp/records/229 jpn
