Abstract

Background: Abundant researches had been conducted based on the clinical and histopathological pathogenesis of aggresive periodontitis. Nevertheless, there were still few researches which based on molecular biology, and especially related to gene polymorphism. This study was done based on IL-1A +4845G→T gene polymorphism in aggressive periodontitis patients. Purpose: The purpose of this tudy was to characterized the generic variation of IL-1A +4845G→T as a risk factor aggressive periodontitis and chronic periodontitis. Methods: DNA from patients with aggressive periodontitis and chronic periodontitis was taken determination of IL-1A +4845 G→T polimorphism was conducted with PCR-RFLP technique. Results: Homozygous allele TT polymorphism was not found in all samples, only allele GG (wild type) and allele GT (heterozygous mutant) were not affect aggressive periodontitis and chronic periodontitis. Conclusion: The study showed there was no significant association between IL-1A +4845G→T gene polymorphism and aggressive periodontitis and chronic periodontitis. Latar belakang: Penelitian tentang patogenesa periodontitis agresif berdasar klinis dan histopatologi telah banyak dilakukan, akan tetapi penelitian berdasar biologimolekuler terutama polimorfisme gen masih sangat jarang dilakukan. Penelitian ini dilakukan berdasarkan pada polimorfisme gen IL-1A +4845G→T pada penderita periodontitis agresif. Tujuan: Tujuan dari penelitian ini adalah untuk mengetahui variasi genetik dari IL-1A +4845G→T yang merupakan faktor risiko periodontitis agresif dan periodontitis kronis. Metode: DNA dari penderita periodontitis agresif dan periodontitis kronis diisolasi, selanjutnya dilakukan determinasi dari polimorfisme gen IL-1A +4845G→T dengan menggunakan teknik PCR-RFLP. Hasil: Pada seluruh sampel penelitian ini tidak dijumpai polimorfisme allel TT (homosigot mutan), yang didapat adalah jenis allel GG (wild type) dan allel GT (heterosigot mutan) yang tidak berpengaruh terhadap periodontitis agresif dan periodontitis kronis. Kesimpulan: Polimorfisme gen IL-1A +4845G→T tidak mempunyai hubungan terhadap kejadian periodontitis agresif dan periodontitis kronis.

Abstract

Nasopharyngeal carcinoma (NPC) is a unique epithelial malignancy that occurs at a high frequency in certain regions of Southeast Asia. Previous study revealed the association between Epstein Barr Virus (EBV) and to a lesser extent, Human Papilloma Virus (HPV) with NPC. The role of the EBV in the pathogenesis of NPC was further supported by the recovery response of the tumor cells after being treated with EBV-specific T lymphocytes. The present study aims to determine the frequency distribution of EBV infection among the pathologically confirmed NPC patients and healthy control in Surabaya, Indonesia. The presence of Human Papilloma. Virus infection (HPV) was also analysed. The results indicated that EBV DNA existed in the 88% of the nasopharyngeal tissue biopsies of 25 NPC patients and none in the 10 healthy controls, and the difference was statistically significant.Analysis of the mononuclear cells of peripheral blood revealed that 60% of the 25 NPC patients carried EBV DNA whereas in control group 20% was found to be positive and the difference was statistically significant. Although a high positive rate EBV-DNA was detected in NPC patients, additional environmental and genetic factors must still be considered. Nevertheless, no HPV-DNA was detected from mononuclear cells of peripheral blood and nasopharyngeal tissue of the two groups. By this study there was no coexistence between the infection of EBV and HPV which promote carcinogenesis in NPC. Analysis using LMP1-DNA in tumor cell biopsies indicated that 72% of the NPC patients yielded PCR products and none of the healthy control, the difference was statistically significant. In conclusion the findings confirm the tight association between the EBV and NPC in Indonesia and that the specific presence of LMP1-DNAs in the tumor cells strongly indicates the important role of EBV in the pathogenesis of NPC. Coexistence of EBV and HPV infections was not found in NPC cases in Indonesia.

Abstract

Diabetes mellitus (DM) is one of disease that its incidence increases every year worldwide. The condition of DM can cause various complications caused by oxidative stress. Stichopus hermanii (SH) or golden sea cucumber extract contains antioxidant compounds that have been proven to reduce oxidative stress conditions. The purpose of this study was to investigate the effect of Stichopus hermanii extract on condition of diabetes mellitus by looking at changes in fasting blood glucose, plasma insulin, and malondialdehyde levels in animal models of Wistar rats. This study was a laboratory experimental study using Randomized Control Trial Design with Post-test only control group design. Thirty-five male Wistar rats divided into five groups, i.e normal control group, positive control, negative control and two treatment groups with SH extract dose 8.5 and 17 mg / kgBW for 14 days once daily after induction of Streptozotocin at the Biochemistry Laboratory of the Faculty of Medicine, Airlangga University. Fasting blood glucose level was measured by a glucometer, plasma insulin measured by ELISA and MDA level was measured by a spectrophotometer. Data were analyzed statistically by using One Way ANOVA test and Kruskal Wallis. There were significant results of SH extract can reduce fasting blood glucose (Kruskal Wallis, p=0.030) and MDA (Kruskal Wallis, p=0.042) but not in plasma insulin (ANOVA, p=0.130). The lowest MDA level occurs in the K4 group that given SH extract dose 17 mg/kg BW than another experimental group. As the conclusion, this study showed SH extract can decrease fasting blood glucose and oxidative stress in diabetic-induced rats.

Abstract

Introduction: Streptococcus mutans is a gram-positive coccus commonly found in the human oral cavity and is a pathogen of dental caries. S. mutans known to form biofilm in infective endocarditis heart-valve. Fluoride usage known to reduce the risk of dental caries. This study aims to analyze how usage of fluoride in inhibiting S. mutans growth.Methods: This study was an experimental study. Antibacterial activity test was performed to evaluate the minimum inhibitory concentration (MIC) using dilution method of sodium fluoride. The minimum bactericidal concentration (MBC) was determined by culturing from the previous dilution test into Chocolate Agar Plate.Results: MIC for sodium fluoride is 4,8 mg/ml and the MBC for sodium fluoride to S. mutans is 4,8 mg/ml. We found S. mutans growth in higher concentration than 19,2 mg/ml. Conclusion: S. mutans was inhibited in dilution test. Growth of the bacteria in higher concentration of sodium fluoride is explained with quasi-irreversible inhibtior effects of fluorida.
