Abstract

Background: Inflammation is a body response caused by injury and infection. Pulpitis is a pulp tissue inflammation which is the continuous process of pulp hyperemia by bacteria invasion. Myrmecodia pendans or Sarang semut is known to contain flavonoid compound which has the anti inflammation effect. The purpose of this study is to investigate the effect of Myrmecodia pendans ethanol extract on the healing process of pulp inflammation.Materials and Methods: This experimental study involved pre- and post-in vivo treatment of 27 Sprague Dawley rats in which the inducted pulpitis model was obtained by injecting 0.01 mL Porphyromonas gingivalis into the dental pulp for 48 hours. Subjects were divided randomly into Group I (negative control), Group II (pulpitis treated by Myrmecodia pendans extract ethanol as treatment group), and Group III (pulpitis treated by Ca(OH)2 as positive control group). Group II and III as pulpitis treatment groups were divided into subgroups based on the induction periods of 48 hours (2 days), 168 hours (7 days), and 366 hours (14 days). All specimens were processed into the slides and evaluated microscopically for the healing process.Results: The result of this study showed significant difference (p<0.05) among groups on day 2, 4 and 7. On day 4, the pulpitis treatment group of Myrmecodia pendans extract showed better healing process than Ca(OH)2. On day 7, the pulpitis treatment group of Ca(OH)2 showed better healing process than Myrmecodia pendans extract. On day 14, both of the pulpitis treatment groups showed normal pulp.Conclusion: Myrmecodia pendans ethanol extract is effective for the healing process of inflamed pulp.Keywords: inflamed pulp, Myrmecodia pendans, sarang semut, Ca(OH)2 , healing process

Abstract

Background: Angiogenesis is an important and fundamental process for new blood vessels to provide nutrients and oxygen needed by tumor cells to grow, develop, and in case of cancer also to metastasize into other organs. This study aims to evaluate the intensity of angiogenesis within benign (papillomas) and malignant (squamous cell carcinoma) epithelial tumors.Materials and methods:  This analytic observational study with cross-sectional design using histopathology slide sample that were clinically diagnosed as squamous cell carcinoma (n=3) and papilloma (n=3). Microscopically, the angiogenesis characterized with lumen lined by endothelial cells with or without red blood cells inside within sub epithelial connective tissue of papilloma and squamous cell carcinoma by Hematoxylin Eosin stain. Angiogenesis intensity was counted from four areas under magnification of (10x10), each area was scored under (10x40) magnification.Results: Angiogenesis intensity of papilloma and squamous cell carcinoma are (45.17±14.573) and (55.18±6.26041) respectively. T-test analysis showed there was no significant difference (p=0.336>0.05).Conclusions: Angiogenesis intensity of papilloma is less than those of squamous cell carcinoma.Keywords: angiogenesis, oral epithelial tumor, benign, malignant

Abstract

Background: Recently we have isolated and cultured dental pulp stem cell (DPSC) derived from impacted third molar (DPSC-M3). The DPSC-M3 was suggested as mesenchymal stem cell, however the cell surface markers were not completely clarified. Therefore current study was conducted to investigate the markers.Materials and Methods: Passage 5 DPSC-M3 was cultured, labeled and examined with flow cytometer. All markers were investigated according to the proposed cell surface marker panel for the minimal identification of human mesenchymal stem cell (MSC) by International Society for Cellular Therapy (ISCT). The positive markers were cluster of differentiation (CD)90, CD73, CD105, while the negative markers were CD34, CD45, CD11b, CD19, and Human Leukocyte Antigen (HLA)-DR. Results: Results showed that the size and granularity of DPSC-M3 were ranged from 75 to 230 and 27 to 203, respectively. The cell surface antigens examination showed that CD90, CD105 and CD73 were highly expressed (>95%), meanwhile expressions of CD45, CD34, CD11b, CD19 and HLA-DR were <2%.Conclusion: Since the all markers expression were in accordance to the proposed cell surface marker panel for the minimal identification of human MSC by ISCT, DPSC-M3 could be suggested as an MSC.Keywords: dental pulp, stem cell, dental pulp stem cell, ISCT, flow cytometry
