The Use of PCR-RFLP (Polymerase Chain Reaction-Restriction Fragment Length Polymorphism) to find out the potential of mitochondrial DNA mutation at A3243G in type II Diabetic Patient has been done. Peripheral blood from 100 Indonesian type 2 diabetic subjects was selected randomly for this experiment. Peripheral blood lymphocyte was isolated, lysed, and it was in vitro amplified by PCR using a pair D1/D2 primers. PCR products were 294 base pair (bp) fragments which were then purified by ethanol precipitation method and characterized by restriction enzyme ApaI. Heteroplasmic A3243G mutation which was identified in 2 Subject (0,02%) was shown by 3 electrophoretic bands, 2 restriction products of APAI, i.e a 182 bp fragment and a 112 bp fragment; also a full fragment 294 bp, this means show that PCR-RFLP technique was approved for identifying heteroplasmic A3243g mutation in a tRNA leu gene mtDNA type 2 DM subject.
Jerawat merupakan penyakit inflamasi kronis pada kulit, yang diperparah oleh infeksi bakteri seperti Propionibacterium acnes dan Staphylococcus epidermidis. Banyaknya kasus resistensi bakteri menyebabkan perlunya antibakteri alternatif, antara lain dari tumbuhan kapuk (Ceiba pentandra L.). Penelitian ini bertujuan memperoleh sediaan krim dengan bahan aktif ekstrak etanol daun kapuk yang efektif terhadap bakteri penyebab jerawat dan stabil dalam penyimpanan. Penelitian dilakukan melalui tahap determinasi tumbuhan dan penyiapan simplisia, ekstraksi simplisia, penapisan fitokimia ekstrak, pengujian aktivitas antibakteri ekstrak, penentuan Konsentrasi Hambat Tumbuh Minimum (KHTM) ekstrak, orientasi basis krim, formulasi dan pengujian kualitas fisik sediaan krim, pengujian aktivitas antibakteri sediaan krim selama penyimpanan dan uji banding aktivitas antibakteri sediaan krim terhadap basis dan ekstrak. Hasil penelitian menunjukkan bahwa ekstrak etanol daun kapuk memiliki aktivitas antibakteri terhadap S. epidermidis ATTC 12228 dan P. acnes isolat klinik dengan KHTM sebesar 0,125% dan 0,078% b/v. Sediaan krim diformulasi menggunakan basis F02 dengan penambahan ekstrak sebesar dua, tiga dan empat kali KHTM. Formula 1 (krim dengan 2x KHTM ekstrak) merupakan sediaan krim dengan kualitas fisik terbaik, karena tampilan organoleptis, pH dan viskositasnya stabil selama 30 hari pada suhu kamar serta tidak mengalami pemisahan fase selama satu tahun. Formula 3 (krim dengan 4x KHTM ekstrak) merupakan sediaan krim dengan aktivitas antibakteri terbaik, terutama terhadap P. acnes isolat klinik. Dari hasil penelitian ini diperoleh formula krim dengan kandungan ekstrak etanol daun kapuk yang efektif terhadap bakteri penyebab jerawat dan stabil selama penyimpanan.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
