    PROBIOTICS EFFECT ON THE GINGIVA OF UNCONTROLLED DIABETIC ALBINO RATS
    (EDJ, 2018-10) Kamel, Samah Mohamed; ElKady, Mohamed Shamel
    Objective: This study was designed to evaluate the effect of using L.Reuteri containing tablets, on the gingiva of uncontrolled diabetic rats both histologically and ultrastructurally. Material and Methods: Thirty adult male albino rats were equally divided into three groups, Group I served as control, Group II: rats were subjected to induction of diabetes mellitus using streptozocin, Group III: rats treated as group II animals and on the next day they were fed daily a probiotic tablet Prodentis containing L. reuteri for 14 days. At the end of the experiment, histological and ultrastructural examination was performed on the gingiva. Results: Rats of group II revealed inflammatory gingiva with loss of normal structure, while that of group III revealed a somewhat normal gingiva in comparison to group II. Conclusion: L.reuteri containg tablets can inhibit gingival inflammation associated with diabetics through its antibacterial and autoinflammatory properties.

    WOUND HEALING AND ANTI INFLAMMATORY EFFECTS OF PROPOLIS IN CRITICAL SIZE DEFECT OF RAT BUCCAL MUCOSA (HISTOCHEMICAL AND IMMUNO HISTOCHEMICAL STUDY)
    (EDJ, 2019-07) Reda, Ahmed; Kamel, Samah Mohamed; Younis, Mohamed Abdel Salam El Baz; Morsy, Reham A.A.
    Objectives: the aim of this study is to evaluate the healing and anti-inflammatory effects of propolis in critical wound defects in rats ‘ buccal mucosa. Subjects& methods: 20 adult male albino rats of average weight 150-250 grams were used. Rats were divided into 2 groups Group I: consists of 10 rats, which were subdivided into 2 sub groups Sub Group I A: consists of 5 rats, the wounds were left un treated for 3 days Sub Group I B: consists of 5 rats, the wounds were left un treated for 7 days Group II: Consists of 10 rats which were subdivided into 2 sub groups Sub Group II A: consists of 5 rats, the wounds were treated with propolis for 3 days Sub Group II B: consists of 5 rats, the wounds were treated with propolis for 7 days The wounds were examined histologically, histochemically and immunohistochemically Results: Histologiacally, histochemical and immunohistochemical results showed that the healing process was faster in propolis treated rats due to anti inflammatory and anti oxidant effects of Propolis. Immunohistochemical labeling of vimentin in propolis treated groups was higher than un treated groups Conclusion: Propolis could improve wound healing by stimulating the proliferation of epithelial cells; and fibroblast proliferation, thus improving wound closure and decreasing inflammation (as prolonged inflammation and the release of inflammatory cytokines could cause tissue damage)
