Metode: Sampel yang digunakan adalah 46 plasma darah. Plasma diekstraksi untuk mendapatkan RNA genom virus sebagai cetakan reaksi RT-PCR dan amplikon digunakan untuk nested PCR. Genom HCV berjumlah 24 diunduh dari GeneBank dan penderetan sekuen DNA dilakukan dengan Software Bio Edit versi 7.0.9.0. Pelacak oligonuklueotida dirancang berdasarkan daerah lestari genom HCV yang terletak pada sekuen internal di antara 2 primer yang digunakan pada nested PCR. Homologi oligonukleotida HCV dianalisis menggunakan teknik Blast di GeneBank. Radioisotop 32P digunakan untuk melabel oligonukleotida. Oligonukleotida berlabel diaplikasikan untuk produk nested PCR menggunakan metode hibridisasi dot blot. Konfirmasi hasil amplifikasi dan hibridisasi dot blot dilakukan menggunakan metode sekuensing DNA. Hasil: Hasil analisis Blast menunjukkan homologi yang tinggi untuk HCV (100%). Hasil nested PCR menunjukkan tiga pola fragmen DNA. Tiga pola tersebut masing-masing adalah genotip HCV 1, 2, dan 3. Primer yang digunakan dalam nested PCR tidak spesifik dinyatakan dengan adanya tiga fragmen DNA sehingga sulit diinterpretasikan. Hasil hibridisasi dot blot menggunakan oligonukleotida yang didesain dalam penelitian ini menunjukkan intensitas dot yang tebal. Semua pola fragmen hasil nested PCR menunjukkan hasil positif dot blot. Hasil hibridisasi dot blot sesuai dengan hasil sekuensing DNA. Kesimpulan: Pelacak oligonukleotida menunjukkan kriteria yang sangat memuaskan secara bioinformatika. Hasil hibridisasi dot blot menggunakan 32P menunjukkan intensitas dot yang tebal dan lebih mudah diinterpretasi dibandingkan dengan hasil nested PCR.
Abstract
Background: This study aimed to design and analyze the applicability of an oligonucleotide probe in radioisotope 32P-based dot blot hybridization for detection of hepatitis C virus. Methods: Forty-six of plasma samples were used. The plasma was extracted to obtain viral RNA genome as template for RT-PCR and the amplicon was used for nested PCR. Twenty-four HCV genomes were retrieved from GeneBank DNA sequence and alignment was performed by Bio Edit Software version 7.0.9.0. An oligonucleotide probe was designed based on a highly conserved region that is located on internal sequence between two primers used for nested PCR. Blast analysis on GeneBank was performed to obtain homology of the oligonucleotide for HCV. The oligonucleotide was then labeled with 32P and dot blot hybridization was applied for nested PCR products. DNA Sequencing was performed to confirm the amplicon and dot blot hybridization results. Results: Blast analysis showed high homology (100%) for HCV. Nested PCR resulted in three patterns of DNA fragments representing HCV genotypes 1, 2, and 3, respectively. The primers used in nested PCR were not specific and resulted in DNA fragments difficult to be interpreted. Dot blot hybridization using the designed oligonucleotide showed high intensity dots. All nested PCR fragments showed the dot blot positive. The dot blot results were in accordance with DNA sequencing that confirmed three patterns of DNA fragments as different HCV genotypes. Conclusion: The oligonucleotide showed excellent bioinformatically criteria. 32P-based dot blot hybridization yielded high intensity dots and was easier to be interpreted than nested PCR assay.

Abstrak :
Hepatitis C Virus (HCV) adalah virus yang menginfeksi hati dan menyebabkan penyakit serius dalam jangka panjang. Pengobatan saat ini menggunakan obat Direct-Acting Antiviral (DAA), namun adanya variasi genotipe dan resistensi terkait mutasi dapat menyebabkan kegagalan pengobatan, sehingga memerlukan pengembangan kandidat antivirus baru. Ekstrak daun P. betle telah dilaporkan memiliki aktivitas anti HCV. Penelitian ini bertujuan untuk mengetahui mekanisme efek antiviral ekstrak daun P. betle terhadap HCV dan potensinya sebagai komplementer dengan telaprevir atau sofosbuvir. Aktivitas antivirus diuji menggunakan sel Huh7it-1 dan HCV genotipe 2a (JFH1a), kemudian dianalisis persentase penghambatan dengan titrasi pada kultur sel dan qRT-PCR. Efek sinergis dan antagonis dengan telaprevir atau sofosbuvir dianalisis dengan perangkat lunak CompuSyn. Analisis in silico juga dilakukan untuk memprediksi interaksi senyawa pada ekstrak daun P. betle dengan protein NS3, NS5A, dan NS5B. Ekstrak daun P. betle diketahui mampu menghambat replikasi HCV, dengan daya hambat pada semua perlakuan lebih rendah dibandingkan kontrol. Kombinasi dengan telaprevir menunjukkan efek antagonis, sedangkan kombinasi dengan sofosbuvir menunjukkan efek sinergis pada konsentrasi tinggi, tanpa menyebabkan toksisitas. Prediksi interaksi mengidentifikasi senyawa ‐fenilpropena‐3,3‐diol diasetat dan 4-Allyl-1,2-diasetoksibenzena memiliki interaksi kuat dengan protein NS5A dan NS5B. Energi ikat masing-masingnya -6,86 kkal/mol dan -6,40 kkal/mol pada NS5A, serta 6,01 kkal/mol dan -5.93 kkal/mol pada NS5B. Dari penelitian ini dapat disimpulkan bahwa, ekstrak daun P. betle mampu menghambat replikasi HCV dan memiliki potensi sebagai komplementer dengan sofosbuvir pada konsentrasi tinggi. ......Hepatitis C Virus (HCV) is a virus that infects the liver and causes serious disease in the long term. Current treatment uses Direct-acting Antiviral (DAA) drugs, but the presence of genotypic variations and resistance-associated mutations cause treatment failure, thus requiring the development of new antiviral candidates. P. betle leaf extract has anti-HCV activity. This study analyzes the antiviral mechanism and its potential synergy with telaprevir or sofosbuvir. Antiviral activity was tested using Huh7it-1 cells and HCV genotype 2a (JFH1a), then the inhibitory activity was analyzed by titration on cell culture and qRT-PCR. Synergistic and antagonistic effects with telaprevir or sofosbuvir were analyzed with CompuSyn software. In silico analysis was also carried out to predict the interaction of compounds in P. betle leaf extract with NS3, NS5A, and NS5B proteins. P. betle leaf extract is known to be able to inhibit HCV replication, with virus inhibition in all treatments being lower than the control. The combination with telaprevir showed an antagonistic effect, while the combination with sofosbuvir showed a synergistic effect at high concentration without causing toxicity. Interaction prediction identified the compounds 1-phenylpropene-3,3-diol diacetate and 4-allyl-1,2- diacetoxybenzene as having strong interactions with the NS5A and NS5B proteins, with binding energies of -6.86 kcal/mol and -6 .40 kcal/mol in NS5A, and 6.01 kcal/mol and -5.93 kcal/mol in NS5B, respectively. Based on this research, we conclude that P. betle leaf extract can inhibit HCV replication and has the potential to act as a complement to sofosbuvir at high concentrations.

Abstrak :
Until recently the etiology and pathogenesis of oral lichenoid reaction remain unclear. Usually lichenoid reaction is associated with systemic disease or particular drugs such as ACE inhibitor anti hypertension and several dental materials. Amalgam restorations have been reported as most frequent cause of oral lichenoid reaction induced by dental materials. Mercury hypersensitivity is predicted to be responsible in inducing the reaction. The aim of this review was to describe oral lichenoid reaction associated with hypersensitivity to dental amalgam, so the clinician can manage the cases properly. In conclusion, replacement the amalgam filling which contact to the oral mucosa with other inert dental materials would be useful for hypersensitive patient.

ABSTRAK
Anti-HCV menjadi marker serologi utama yang digunakan untuk uji saring hepatitis C pada donor darah di Indonesia. Selain serologi anti-HCV, untuk lebih meningkatkan kemananan darah, Unit Transfusi Darah UTD DKI Jakarta juga menerapkan pemeriksaan Nucleic Acid Test NAT . Pemeriksaan anti-HCV tidak dapat membedakan antara infeksi aktif dan infeksi yang telah sembuh. Darah akan dianggap terifeksi HCV apabila salah satu dari pemeriksaan serologi atau molekuler positif, begitupula dengan darah donor dengan hasil pemeriksaan anti-HCV grayzone dan NAT negatif. Diperlukan kepastian atas berisiko tidaknya darah tersebut dalam menularkan infeksi HCV, mengingat kebutuhan darah di sebagian besar provinsi di Indonesia masih belum memenuhi target. Sehingga dibutuhkan uji molekuler lain untuk dijadikan pembanding dengan hasil NAT. Interpretasi hasil anti-HCV dilakukan berdasarkan rasio S/CO, yang dapat dijadikan prediksi status viremia donor, sehingga perlu dilakukan analisis hubungan antara S/CO dengan hasil pengujian molekuler dan HCV Ag-Ab. Nilai prediksi viremia diharapkan dapat menjadi alternatif bagi UTD yang belum mampu menerapkan NAT. Kemudian dipilih 93 sampel dengan kriteria anti-HCV positif dan NAT positif; anti-HCV positif dan NAT negatif serta anti-HCV grayzone dan NAT negatif untuk diuji dengan nested PCR kualitatif dan HCV Ag-Ab. Berdasarkan perbandingan hasil pengujian NAT dan nested PCR diperoleh nilai sensitivitas NAT sebesar 90, 63 , dengan Spesifisitasnya 96,71 . Dari hasil analisis chi-square diperoleh hubungan yang bermakna antara nilai S/CO anti-HCV dengan hasil pengujian NAT, nested PCR kualitatif dan HCV Ag-Ab P5 dapat dijadikan prediksi adanya infeksi aktif pada donor.
ABSTRACT
Anti HCV is the main serological marker for hepatitis C screening in blood donors in Indonesia. Besides anti HCV, UTD DKI Jakarta also implementing Nucleic Acid Test NAT to improve blood transfusion safety. Anti HCV assay can not distinguish between active infection and cured infection. Blood will be considered HCV infected if either from a positive serologic or molecular test, including blood with anti HCV grayzone and NAT negative. There is a requirement to ensure the risk status of blood with anti HCV grayzone and NAT negative, because the supply of blood in most provinces in Indonesia still insufficient. So, it takes another molecular test to compare with NAT result. Interpretation of anti HCV results was calculating by S CO ratio, which could be a predictor of viremia status. It is necessary to analyze the correlation between S CO with molecular test and HCV Ag Ab results.Viremia prediction value is expected to be an alternative for UTDs who have not been able to apply NAT. There are 93 samples collected then tested with NAT and anti HCV. Sample with concondantly positive anti HCV and NAT anti HCV positive and NAT negative and anti HCV grayzone and NAT negative. These samples then tested with nested PCR and HCV Ag Ab. Based on comparison of NAT and nested PCR, obtained NAT sensitivity value of 90, 63 , with Specificity 96.71 . The result of chi square analysis shows a significant correlation between S CO anti HCV with NAT, qualitative nested PCR and HCV Ag Ab P 5 can be used as predictors of active infection in donors.
