Abstract

Enterococcus faecalis can withstand harsh environmental conditions in the root canal and cause a secondary infection. Myrmecodia pendens is an herbal medicine rich in polyphenol compounds that have antibacterial, antioxidant, and anticancer properties. Objectives: To analyze the effects of M. pendens fraction combination on the sensitivity of E. faecalis. Methods: The minimum inhibitory concentration (MIC) was determined using a serial microdilution method, and the minimum bactericidal concentration (MBC) was determined by adding the test sample to sterile Mueler Hinton agar medium. Results: The MIC of combination 1 (hexane-ethyl acetate, HE) was 0.049 mg/mL, whereas those of combinations 2 (hexane-water, HA) and 3 (ethyl acetate-water, EA) were 0.098 and 0.390 mg/ mL, respectively. The MIC of NaOCl was 0.390 mg/mL, and that of methanol extract was 0.390 mg/mL. The MBC of combination 1 (HE) was 12.50 mg/mL, whereas that of combinations 2 (HA) and 3 (EA) was 50 mg/mL. The MBC of NaOCl was 25 mg/mL and that of methanol extract was 50 mg/mL against E. faecalis. This study showed that fraction combinations increase the antibacterial effect of M. pendens against E. faecalis ATCC 29212. Conclusion: The HE fraction combination showed the best effect against E. faecalis and can be developed as an alternative endodontic irrigant

Abstract

Thalassemia merupakan penyakit herediter yang diturunkan secara autosomal resesif. Thalassemia dibedakan berdasarkan variasi mutasi pada gen globin yaitu gen α-globin (HBA) pada α-Thalassemia dan β-globin (HBB) pada β-Thalassemia. Penelitian ini bertujuan untuk mengetahui potensi pemodifikasi genetik pada penderita β-Thalassemia. Data sistimatika review dengan pengumpulan jurnal terkait pada cangkupan kata kunci yang dikomplikasikan prinsip PRISMA. Beberapa hasil studi melaporkan polimorfisme dan atau mutasi pada gen KLF1, BCL11A dan region intergenik HBS1L-MYB sebagai pemodifikasi genetik pada β-Thalassemia, didapatkan sembilan jurnal yang masuk ke dalam kriteria inklusi. Berdasarkan hasil review yang dapat ditelaah bahwa pemodifikasi genetik pada kasus β-Thalassemia diketahui adanya mutasi atau polimorfisme pada gen-gen berikut KLF1, BCL11A, dan HBS1L-MYB cenderung meningkatkan produksi HbF dengan mengatur ekspresi γ-globin dan memperbaiki gejala klinis pasien β-Thalassemia. Simpulan dari kasus tersebut menjadikan peluang di kemudian hari untuk perawatan pasien yang dipersonalisasi disesuaikan dengan fenotipe yang meringankan gejala penderita β-Thalassemia.
