HISTOCHEMICAL STUDY ON THE EFFECT OF ZINE-DEFICIENT DIET ON THE SUBEPITHELIAL CONNECTINE TISSUE OF ABBINO RAT ORAL MUCOSA

아연결핍이 백서구강점막상피하 결합조직에 미치는 영향에 관한 조직화학적 연구

The purpose of the current study was to evaluate the effect of the zinc-deficient diet on the connectine tissue of oral mucosa in the albino rats. The zinc dificient diets were supplied to the rats for 4 weeks. The results were as follows: Most of the papillas of lamina prmina propria were shortened. The abnormal distribution and orientation of the fibrous elements were observed. The stain ability of fihrous elements in the Mallory azan stain was decreased. The amorphous intercellular substance showed slight metachromasia in the toluichine blue stain and low PAS reactinity.
