Abstract

Background: Excessive consumption of durian (Durio zibethinus Murray) in Indonesia is often connected with its effect on health. This study aims to understand the effect of durian consumption to malondialdehyde (MDA) in plasma as oxidative stress biomarker.Methods: The study used an experimental research design on animal models, in the Biochemistry and Molecular Biology Department, Faculty of Medicine, Universitas Indonesia, July–August 2012. Thirty two Sprague-Dawley rats were used, divided into four groups: control, treatment week 1, 2, and 3. Each treatment group was given 20 gram durian fruit diluted with water until 20 ml volume per oral, divided into two doses (10 ml each) with 4 hours interlude between doses for 1 week, 2 weeks, and 3 weeks. All groups got normal diet and water ad libitum. Plasma MDA level was measured by TBARS method, then analyzed using Kurskal-Wallis and Mann-Whitney tests.Results: Seventeen samples were successfully decapitated (5 for control; 6 for week 1; 3 for week 2; 3 for week 3). Average plasma MDA level for control treatment week 1, 2 and 3 groups were 0.707 nmol/ml, 0.432 nmol/ml, 0.312 nmol/ml, and 0.746 nmol/ml respectively. Data was significant (p<0.05) with p=0.02. Compared with control group, a significant increase occurred in week 1 and 2 groups with p=0.028 and p=0.025 respectively.Conclusions: Results of durian consumption show MDA level significantly decreases in week 1 and 2. However, MDA level dramatically increases exceeding control group level in week 3. [AMJ.2016;3(1):22–8] DOI: 10.15850/amj.v3n1.695

Abstract

Deoxyribonucleic acid (DNA) is a genetic material which is found in all living organisms. On the human cell or eukaryotes cell, the DNA is found in the nucleus cell and the mitochondria. The DNA arrangement on each cell in human body is the same, that is why, for the analysis meaning, DNA can be isolated from any cell in the body. The source of DNA to be analyzed usually coming from the blood sample by an injection method, such a way resulting in pain and bringing about constraint. Therefore, a study was carried out to look for an alternative of DNA isolation. The aim of this experimental study was to get an optimal DNA isolation method by using oral mucous smear method with a purpose to get a quick and easy DNA isolation. The investigation materials were in the form of samples which were taken from the oral epithelial mucous cells out of three different subjects. The epithelial cells were obtained by the oral mucous smear method which in a variation of two, four and six times of smear applications, respectively. The DNA was then isolated using buffer extraction method. The concentrations of DNA were measured by using ultraviolet spectrophotometer at 260 nm wavelength. The results of DNA isolation were analyzed by Polymerase Chain Reaction (PCR) technique. The optimal DNA isolation could be analyzed by PCR technique. The experimental results show that from three different subjects of study, DNA can be isolated optimally by oral mucous smear method with six times of smear applications.

Abstract

Introduction: Lipid peroxidation, one of the known indices of oxidative stress, is documented in various diseases. Secondary oxidation products such as malondialdehyde (MDA) is commonly measured to observe lipid peroxidation. In this study, a spectrophotometric method was evaluated to measure thiobarbituric acid reactive substances (TBARS) with high sensitivity. This study was aimed to optimisation standard of MDA using tetraethoxypropane (TEP) 97% (FW=220.3). Methods: The method is based upon the reaction of malondialdehyde (MDA) and TBA in the glacial acetic acid medium. MDA is a known biomarker of oxidative status in a biological system. This research consists of two phases: first, making a stock of TEP, and the second phase was testing the concentration of TEP for finding the standard curve of MDA before used in diagnostic of lipid peroxidation. Results: Result showed the concentration 1,875-60 uM of TEP could form a precise standard curve. Conclusion: This concentration of TEP can be used as a reference as the standard of control in diagnostic of lipid peroxidation using TBARS method.

Abstract

BackgroundIneffective erythropoiesis and multiple blood transfusions may cause iron overload, leading to high level of ferritin in β-thalassemia patients. Iron has the ability to catalyze the production of reactive oxygen species (ROS), which can be prevented by an adequate activity of superoxide dismutase (SOD) and glutathione peroxidase (GPx). The aim of this study was to explore the association between high ferritin levels and oxidative stress among β-thalassemia patients by measuring SOD and GPx levels. MethodsThis was a cross sectional study among β-thalassemia major patients. Ferritin, SOD, and GPx were measured and compared between β-thalassemia patients with homozygous IVS1nt5 and heterozygous IVS1nt5/HbE mutations, which were the most prevalent mutations found in our previous study. The Spearman correlation test was used to analyze the data. ResultsThe ferritin levels in all β-thalassemia major patients were very high (range: 791-12,340 µg/L). However, no significant differences were observed (p=0.318) between homozygous IVS1nt5 (n=45) compared to heterozygous IVS1nt5/HbE (n=13). The oxidative stress markers SOD and GPx were not significantly different between homozygous IVS1nt5 and heterozygous IVS1nt5/HbE (p=0.450 and p=0.323, respectively). The correlations between ferritin and SOD and GPx oxidative stress levels were not significant in both homozygous IVS1nt5 and heterozygous IVS1nt5/HbE mutations. ConclusionHigh ferritin levels in β-thalassemia patients tend to decrease the GPx level in all thalassemia patients and SOD level in half of the patients, indicating that GPx and SOD may play a role in the occurrence of oxidative stress among thalassemia patients. The mechanism of oxidative stress in thalassemia needs to be further explored.

Abstract

Streptococcus sanguinis merupakan bakteri pionir penyebab plak gigi. Penggunaan obat kumur klorheksidin merupakan tindakan untuk mengontrol pembentukan plak gigi, namun karena efek sampingnya, klorheksidin tidak dapat digunakan untuk jangka panjang. Umbi sarang semut (Myrmecodia pendens) merupakan tanaman obat yang memiliki banyak aktivitas biologis untuk kesehatan. Penelitian ini bertujuan menguji aktivitas antibakteri ekstrak kasar umbi sarang semut terhadap bakteri S. sanguinis dibandingkan dengan klorheksidin dan pengaruh pemberian konsentrasinya terhadap kematian sel bakteri. Metode penelitian menggunakan uji  Kirby-Bauer untuk menentukan diameter hambat pertumbuhan bakteri, dilanjutkan dengan uji MIC untuk mengetahui nilai MIC dari sampel dan pengaruhnya terhadap kematian sel bakteri. Penelitian dilakukan pada bulan Agustus-Oktober 2015 di Laboratorium Kimia Organik Universitas Padjadjaran Hasil uji Kirby-Bauer ekstrak kasar umbi sarang semut menunjukkan aktivitas antibakteri. Zona hambat yang dihasilkan oleh ekstrak kasar tidak berbeda signifikan dengan klorheksidin (12 mm vs 15 mm, p>0,05). Nilai MIC ekstrak kasar berada diantara 9,77 ppm dan 19,53 ppm, nilai ini lebih kecil dibanding dengan klorheksidin, yaitu sebesar 1,935 ppm. Selain itu, terdapat korelasi positif dan kuat antara konsentrasi ekstrak kasar dan kematian sel bakteri S. sanguinis (r=0,867). Dapat disimpulkan ekstrak kasar umbi sarang semut memiliki efek antibakteri lebih kecil dibanding dengan klorheksidin. Peningkatan konsentrasi eksrak kasar umbi sarang semut memiliki korelasi positif dan kuat terhadap peningkatan kematian sel bakteri S. sanguinis.

The use of chlorhexidine mouthwash is one of the treatments to control dental plaque. However, due to its side effects, chlorhexidine cannot be used in a long period. Ant nest tuber (Myrmecodia pendens) is one of the medicinal plants with variousbiological activities that are beneficial to human health. The purpose of this study was to examine the antibacterial activity of ant nest tuber crude extract against bacteria S. sanguinis compared to chlorhexidine and measure the effect of increased concentration on bacterial cell death. This study was conducted using Kirby-Bauer method to measure the diameter of bacterial growth inhibition in August?October 2015 at the Organic Chemistry Laboratory of Universitas Padjadjaran. The MIC was then measured to determine the MIC values of the sample and the effect on bacterial cell death. Kirby-Bauer test showed that the inhibition zone produced by crude extract was not significantly different from the one produced by chlorhexidine (12 mm vs 15 mm, p>0.05) when both were used to inhibith the growth of S. sanguinis. The MIC value of crude extract was between 9.77 ppm and 19.53 ppm, smaller than the MIC value of the chlorhexidine of 1.93 ppm. In addition, there was a positive and strong correlation (r=0.867) between the concentration of crude extract and S. sanguinis cell death.  Hence,  crude extract from ant nest tuber has a lower antibacterial effect than chlorhexidine in inhibiting the growth of S. sanguinis. Additionally, there is a strong correlation between the increased concentration of crude extract and increased S. sanguinis cell death.

Abstract

Tuberkulosis (TB) adalah penyakit infeksi yang disebabkan oleh Mycobacterium tuberculosis. Faktor kuman saja tidak dapat menjadi faktor tunggal dalam kejadian TB. Varian polimorfisme gen reseptor vitamin D (RVD) dianggap penting hubungannya dengan kerentanan dan resistensi terhadap TB. Penelitian ini bertujuan untuk mengetahui peran polimorfisme FokI, BsmI, ApaI, dan TaqI gen RVD terhadap kejadian TB anak. Penelitian observasional analitik dengan rancangan kasus kontrol ini dilakukan di Bagian Ilmu Kesehatan Anak RSUP Dr. Hasan Sadikin Bandung dan Rumah Sakit Umum Cibabat Cimahi sejak Mei 2008–Maret 2009. Sampel terdiri dari 42 anak TB (kelompok kasus) dan 42 anak non-TB (kelompok kontrol) yang memenuhi kriteria penelitian dan diambil secara consecutive sampling. Dilakukan pemeriksaan polimorfisme FokI, BsmI, ApaI, dan TaqI gen RVD. Analisis dengan uji Chi-kuadrat, uji Mann-Whitney, menghitung rasio Odds (OR) dan 95% CI. Kejadian polimorfisme FokI gen RVD pada kelompok kasus TB 66,7% dan kontrol 40,5% (p=0,016) dengan OR (95% CI): 2,94 (1,21–7,16). Kejadian polimorfisme FokI gen RVD untuk kelompok kasus TB adalah 2,94 kali lebih banyak dibandingkan dengan kontrol. Polimorfisme BsmI, ApaI, dan TaqI gen RVD tidak terdapat perbedaan bermakna antara kelompok kasus TB dibandingkan dengan kontrol (p >0,05). Disimpulkan bahwa polimorfisme FokI gen RVD merupakan faktor risiko terjadinya TB anak.

Abstract

Cervical cancer is the second most common cancer among women in the world. Persistent infection with high risk human papillomavirus (HPV) is one of the necessary causes of cervical cancer development. However, host genetic factors may also play a role in cervical cancer carcinogenesis. Methylenetetrahydrofolate reductase enzyme, encoded by the MTHFR gene, regulates folate metabolism which is important for genetic expression and stability. Single nucleotide polymorphism (SNP) C677T in MTHFR gene may produce a thermo-labile enzyme, resulting in a reduced enzyme activity. The aim of this study was to explore the SNP C677T of MTHFR gene and the susceptibility to cervical cancer among cancer patients visiting Dr. Hasan Sadikin General Hospital, Bandung, Indonesia. This descriptive quantitative study involved cervical cancer patients recruited in 2010 and their control group. Genomic DNA was extracted from patients’ blood. MTHFR C677T genotype was performed using BeadXpress Reader Illumina® and some samples were re-genotyped for confirmation using conventional PCR-RFLP. The distribution of MTHFR C677T genotype in cervical cancer patients was 71.6%, 25.4%, and 3%, and 44%, 36%, and 20% in control group for CC, CT, and TT, respectively. This yielded a statistical significant difference of CC vs CT+TT (p 0.014 with OR 3.22 and CI 95% 1.24 – 8.33). Taken together, this result indicates that T allele has a protective effect against cervical cancer development. Further studies to confirm this effect in bigger population is warranted.

Infeksi persisten oleh human papillomavirus (HPV) tipe risiko tinggi merupakan salah satu penyebab utama kanker serviks. Selain itu, factor genetic juga turut berperan dalam proses perkembangan kanker serviks. Enzim methylenetetrahydrofolate reductase yang disandi oleh gen MTHFR berfungsi meregulasi metabolism folat. Polimorfisme C677T pada gen MTHFR dapat membuat produksi enzim menjadi termolabil sehingga terjadi penurunan aktivitas. Distribusi folat yang abnormal dapat mengganggu proses metilasi, sintesis, dan perbaikan DNA yang dikaitkan dengan perkembangan kanker serviks. Tujuan penelitian ini adalah mengetahui distribusi polimorfisme C677T gen MTHFR pada pasien kanker serviks di Rumah Sakit Umum Dr. Hasan Sadikin Bandung, Indonesia. Penelitian deskriptif kuantitatif ini melibatkan pasien kanker serviks yang diinklusi tahun 2010 dan sebagai control adalah wanita yang datang untuk pemeriksaan PAPsmear. DNA genomic diisolasi dari darah pasien dan dihibridisasi dengan menggunakan system BeadXpress Reader Illumina® untuk menentukan jenis genotipenya. Genotipe beberapa sampel dikonfirmasi dengan metode PCR-RFLP. Hasil distribusi polimorfisme C677T gen MTHFR dengan genotipe CC, CT, dan TT pada pasien kanker serviks adalah 71,6%, 25,4%, dan 3% dan pada kontrol adalah 44%, 36%, and 20%. Hasil ini menunjukkan perbedaan yang signifikan antara pasien kanker serviks dan kontrolnya, dengan genotipe CC vs CT+TT menunjukkan nilai p=0,014 (OR 3.22 dan IK 95% 1,24–8,33).

Abstract

Vitamin D receptor, encoded by VDR gene, mediates vitamin D functions by not only regulating calcium metabolism and homeostasis but also in regulating immune response. Polymorphisms in VDR gene may increase the progression of human immunodeficiency virus (HIV) infection into acquired immunodeficiency syndrome (AIDS). This study aimed to explore the distribution of VDR polymorphisms among HIV sero-positive patients in West Java. A cross-sectional study was performed, recruiting 96 patients infected with HIV and VDR polymorphisms were analyzed. The genotype distributions of Bsm-I among HIV-infected patients were 2.2%, 18.5%, and 79.3% for BB, Bb, and bb, respectively whereas the distributions of Apa-I were 54.4%, 38.9%, and 6.7% for AA, Aa and aa, respectively. The frequency of VDR polymorphisms in Bsm-I among HIV-infected patients in West Java were considered high for b allele (88.6%), and in contrast for A allele in Apa-I that was 73.91%. Further studies involving healthy controls are needed to explore the VDR polymorphisms distribution in general population. Moreover, a cohort study, albeit challenging, is needed to further assess the association between VDR polymorphisms and the progression of HIV infection.Distribusi Polimorfisme gen VDR Bsm-I rs1544410 dan Apa-I rs7975232 pada Pasien HIV/AIDS di Jawa BaratReseptor vitamin D yang dikode oleh gen VDR mempunyai peranan penting terhadap fungsi vitamin D, tidak hanya dalam regulasi metabolisme dan keseimbangan kalsium namun juga berperan dalam meregulasi respon imun. Polimorfisme pada gen VDR ditengarai dapat meningkatkan progresivitas infeksi human immunodeficiency virus (HIV) menjadi acquired immunodeficiency syndrome (AIDS). Penelitian ini bertujuan mengetahui distribusi polimorfisme gen VDR pada pasien HIV di Jawa Barat. Penelitian ini melibatkan 96 pasien HIV dan dilakukan analisis polimorfisme gen VDR. Distribusi genotip Bsm-I pada pasien HIV di Jawa Barat adalah 2,2%, 18,5%, dan 79,3% untuk BB, Bb, dan bb, secara beurutan; sedangkan pada Apa-I adalah 54,4%, 38,9%, dan 6,7% untuk AA, Aa, dan aa. Frekuensi polimorfisme pada Bsm-I pada pasien HIV di Jawa Barat tergolong tinggi pada alel b (88,6%) dan berbanding terbalik pada dan Apa-I dengan alel A yaitu 73,91%.
