ABSTRACT
OBJECTIVES: This study aimed to evaluate the effects of topical application of Acanthus ilicifolius methanolic extract on signal transducer and activator of transcription 3 (STAT3) expression and tongue epithelial cell death caused by oral candidiasis under immunosuppressive conditions. MATERIALS AND METHODS: To obtain the oral candidiasis model, 20 healthy male Rattus norvegicus (Wistar) rats were administered oral dexamethasone and tetracycline for 14 days and oral candidiasis was induced with Candida albicans (ATCC-10231) 1 McFarland. They were then randomized into four groups-immunosuppression (K-), oral candidiasis (K + ), nystatin treatment (P1), and 20% A. ilicifolius methanolic extract treatment (P2) and were treated for 14 days. Histological analyses of cell death and candida invasion and immunohistochemical analysis of STAT3 in epithelial cells were performed. STATISTICAL ANALYSIS: Epithelial cell death data were analyzed using one-way analysis of variance (ANOVA) and the post hoc Games-Howell test (p < 0.05) and STAT3 expression with one-way ANOVA and the post hoc least significant difference test (p < 0.05). RESULTS: Cell death was significantly different between K- and K+ and between K+ and P1 and P2 (p < 0.05); there were no significant differences between K- and P1 and P2 and between P1 and P2 (p > 0.05). STAT3 expression was significantly different between K- and P1 and P2 and between K+ and P1 and P2 (p < 0.05), but there were no significant differences between K+ and K- and between P1 and P2 (p > 0.05). CONCLUSION: Topical administration of A. ilicifolius methanol extract increased STAT3 expression and decreased tongue epithelial cell death caused by oral candidiasis.
ABSTRACT
OBJECTIVES: This article aimed to investigate the effect of Anadara granosa (AG) shell's-Stichopus hermanni scaffold on cluster of differentiation (CD)44 and interleukin-10 (IL-10) expression to decrease osteoclasts in socket healing. MATERIALS AND METHODS: Thirty male Wistar rats were divided into five groups. The lower left incisor was extracted, then given a placebo for group control (K), the treatment group was administered with scaffold from AG shells, and a treatment group with scaffold from blood cockle shell-S. hermanni with the concentration of 0.4, 0.8, and 1.6% (AGSH0.4; AGSH0.8; AGSH1.6). We made a bone graft from a combination of AGSH extract using the freeze-dried method. The socket was sutured by silk braid immediately. Third and Seventh days postextraction, animals are killed. CD44 and IL-10 expression were examined with immunohistochemistry, as well as osteoclast was examined with hematoxylin-eosin. STATISTICAL ANALYSIS: The data were analyzed using a one-way analysis of variance (for CD44 and osteoclast) and Kruskal-Wallis' test (for IL-10) followed by a post hoc test in which the result of p < 0.05. RESULTS: Scaffold from a combination of AGSH increased CD44 expression significantly, which enhanced IL-10 expression thereby decreased the number of osteoclasts in socket healing on days 3 and 7. CONCLUSION: Scaffold of AG shell-S. hermanni with a concentration of 0.8% was effective to enhance CD44 and IL-10 expression to decrease osteoclast in socket healing after tooth extraction.
