Abstract

Introduction: Dengue virus infection isone of the emergency infectious diseases in the world. Morbidity and mortality of dengue fever in Indonesia is relatively high.There is no specific therapy for dengue infection. The main treatment principle of dengue infection is supportive therapy such as replacement of body fluids. Indonesia has natural product which can be potential as an antiviral for dengue therapy, such as sambiloto (Andrographis paniculata), serai (Cymbopogon citrates) and meniran (Phyllanthus niruri L.). The aim of this research is to determine the effectiveness of the extract of sambiloto (Andrographis paniculata), serai (Cymbopogon citrates) and meniran (Phyllanthus niruri L.) as dengue antiviral in vitro. Methods:This study was a laboratory experimental research using dengue virus serotype 2 strain New guinea C (DENV2 NGC) which was infected into Huh-7 cell line as the subject of the research. This researchwas conducted in 2 parts. First ,inhibition test of the extract against DENV2 was assessed by the percentage of infectivity with Focus Forming Unit assay method . Second ,toxicity test of the extracts in HuH - 7 cells was assessed by the percentage of viability by MTT assay method. Effective herbs extract as a dengue antiviral was an extract that had average percentage of infectivity20% and average percentage of viability > 50%. Results: The extracts of sambiloto, serai, and meniranhad average percentage of infectivity: 53.8%; 114.4%; and 51.9%respectively. While the average percentage of viability were: 105.9%; 95.7%; and 98.6%respectively. Conclusion: The extracts of sambiloto (Andrographis paniculata), serai (Cymbopogon citrates), and meniran (Phyllanthus niruri L.) were not effective as dengue antiviral in vitro. Keywords: Andrographis paniculata, Cymbopogon citrates, Phyllanthus niruri L., DENV2 NGC,HuH-7.

Abstract

Introduction: Drug Induced Liver Injury (DILI) is a liver injury caused by drug toxicity. About 41 out of 100.000 people suffer liver damage due to DILI. Most of this injury caused by excessive use of paracetamol. Meniran (Phyllanthus niruri Linn.) contains antioxidants that can protect liver from damage. The aim of this research was to investigate the hepatoprotective effect of meniran extract on histological damage in liver cells induced by paracetamol. Methods: This was laboratory experimental research with post test only controlled group design. This research was conducted in Histology Laboratory FK UNS. Samples were 30 mice obtained by purposive sampling which characteristics were Swiss webster type, male, 2-3 months old, 20 gr of each weight. Samples divided randomly into 5 groups, each group has six mice. The normal group (KN) was given distilled water only. The negative control group (KK (-)) was given paracetamol toxic dose only. The positive control group (KK (+)) was given Curcuma and paracetamol toxic dose. A gradual dose (2.8 mg and 5.6 mg) of meniran extract was given daily to the first treatment group (KP 1) and second treatment group (KP 2) for 14 days respectively and added with paracetamol toxic dose (5 mg) on day 8th to 14th orally. On day 15th, mice were sacrificed and liver were taken for preparation with HE staining. Liver cells damage was identified by counting nucleus with pyknosis, karryorhexis, and karyolysis from 100 liver cells. Data was analyzed using One-Way ANOVA and Post Hoc Multiple Comparisons-LSD (? = 0.05). Results: One-Way ANOVA showed that there was a significant difference between 5 groups (p < 0.05). Post Hoc Multiple Comparisons-LSD showed that there were significant differences (p < 0.05) between KN-KK (-), KN-KK (+), KN-KP 1, KN-KP 2, KK (-)-KK (+). KK (-)-KP 1, KK (-)-KP 2, KK (+)-KP 1, KP 1-KP 2, but there was not significant difference between KK (+)-KP 2 (p > 0.05). Conclusions: Meniran extract has hepatoprotective effect on histological structure damage of mices liver cells induced by paracetamol in a dose dependent manner. Keywords: Phyllanthus niruri, paracetamol, liver cells histologic damage

Abstract

Introduction: Dengue virus is a type of virus that causes various reactions, from asymptomatic infection to harmful manifestations, such as dengue hemorrhagic fever (DHF) and dengue shock syndrome (DSS). Currently, the treatments of DHF cases have been limited to symptomatic and supportive therapies only. Therefore, it is necessary to develop new strategies in facing these cases. One of them is by using natural ingredients with antiviral potential. The aim of this study is to understand the antiviral effects of the ethanol extract of red ginger rhizome (Zingiber officinale Linn var. rubrum) against dengue virus in vitro. Methods : The subject of this research was Dengue virus serotype 2 strain New guinea C (DENV-2 NGC) which was infected into Huh-7 cell line. The research was divided into 2 parts. The first was inhibition test of the extract against DENV-2 which was assessed by average of infectivity percentage with Focus Forming Unit assay method. The second was toxicity test of the extract in Huh 7 cells which was assessed by average of viability percentage by MTT assay method. The herb extract effective as a Dengue antivirus was defined by average infectivity percentage of ? 20% and average viability percentage of > 50%. Results: Ethanolic extract of Red Ginger rhizome (Zingiber officinale Linn var. Rubrum) with concentration 80, 40, 20, 10, 5, 2.5 g/ml had average percentage of infectivity respectively: 9.2% ; 25.3% ; 32.3% ;47.5% ; 66.6% ; 73.4%. While the average percentage of viability were: 92.2% ; 94.3% ; 96.7 % ; 99.6% ; 102.7% ; 105.9%. Conclusions: Ethanolic extract of rhizome Red Ginger (Zingiber officinale Linn var. Rubrum) is not effective in inhibiting the replication of dengue virus serotype DENV-2 in vitro because it has the average infectivity percentage ? 20 and has no toxic effects on cells Huh-7 because it has the average viability percentage > 50. Key Words: Zingiber officinale Linn var. rubrum, Dengue virus, DENV-2, Huh-7 cell line.

Abstract

Introduction: Measurement of hemoglobin concentration can be done by hematology analyzer (HA) cyanmethemoglobin method (gold standard) and point-of-care testing (POCT) electrode-based biosensor method. POCT electrode-based biosensor method is one of the hemoglobin POCT and has not been studied before in Indonesia. This study examined the difference and correlation hemoglobin concentration by HA cyanmethemoglobin method and POCT electrode-based biosensor method. Methods: This was a cross sectional study in 4 senior high schools of Sukoharjo in Indonesia on Desember, 2016. Senior high schools were selected using a simple random sampling and senior high schools grade selected using a stratified random sampling. Among 173 grade 10 and 11 senior high school girls in this study the capillary and venous blood samples were collected. Capillary blood sample collected was immediately processed to measure the hemoglobin concentration using POCT electrode-based biosensor method and venous blood sample was collected to measure the hemoglobin concentration using HA cyanmethemoglobin method. Statistical analyses used were Mann-Whitney and Spearmans correlation coefficient (?=0.05). Results: Hemoglobin concentration determined by the POCT electrode-based biosensor method compared to HA cyanmethemoglobin method was significantly different (p=0.000 ) and there was positive moderate correlation (r=0.438; p=0.000). Conclusions: Hemoglobin concentration assessment by POCT electrode-based biosensor method has shown significantly different and positive correlation with HA cyanmethemoglobin method. Keywords: hemoglobin concentration, HA cyanmethemoglobin method, POCT electrode-based biosensor method
