Uji Fenotipik Deteksi Enzim ESBL, AmpC dan Karbapenemase pada Bakteri Enterobacteriaceae
Authors: Dharmawan Ade , Layanto Nicolas
Published: April 2020

Organisme yang mengekspresikan extended-spectrum β-lactamases (ESBLs) seperti Enterobacteriaceae dilaporkan semakin meningkat selama empat puluh tahun terakhir. Organisme yang meng-ekspresikan enzim ini dapat menghidrolisis oksminosefalosporin dan monobactam, namun dapat dihambat menggunakan β-laktam inhibitor. Terdapat berbagai macam enzim yang berkontribusi dari resistensi sefalosporin dan monobaktam seperti AmpC β-lactamase, dan enzim karbapenemase. Polymerase Chain Reaction (PCR) merupakan metode yang akurat dalam mendeteksi ESBL, tetapi metode ini merupakan metode genotipik yang membutuhkan alat khusus, sehingga masih dibutuhkan metode fenotipik untuk mendeteksi enzim ESBL, AmpC dan Karbapenemase yang dapat dilakukan pada berbagai laboratorium.

Authors: Reynaldo Giovanni , Desiree Audrey
Published: April 2020

Guillain-Barré Syndrome (GBS) merupakan suatu kelainan mediator imun dari sistem saraf perifer dimana respon autoimun menjadi aktif dan menargetkan saraf perifer. Patogenesis GBS dipercaya sebagai sebuah respon imun yang abnormal terhadap sebuah kejadian yang terjadi sebelumnya, paling sering didahului oleh suatu infeksi, dan pada sebagian kecil kasus dilaporkan pasca imunisasi terutama untuk pasien anak-anak. Manifestasi klinis GBS berupa kelemahan ekstremitas bilateral progresif yang cepat dan bersifat ascending. Terapi yang masih digunakan dan dianggap efektif untuk saat ini yaitu immunoglobulin intravena (IVIg), dan plasmaferesis. Modalitas terapi baru seperti Interferon-β (IFN-β), Siklofosfamid, dan antibodi monoklonal manusia masih memerlukan penelitian lebih lanjut terkait efektivitas dan efek samping yang bisa terjadi. Prognosis GBS anak didapatkan lebih baik, mortalitas juga ditemukan lebih rendah yaitu sekitar 1-2% pada anak dengan GBS, dan hanya 4% dari seluruh pasien anak yang membutuhkan alat bantu pernapasan selama perawatan.

PENGARUH EKSTRAK BUAH DELIMA MERAH TERHADAP KADAR SOD PADA KULTUR HUVECs YANG DIPAPAR PLASMA PREEKLAMPSI
Authors: Januarsih Januarsih
Published: April 2020

Preeklampsi merupakan sindroma yang berkaitan dengan adanya gejala vasospasme, peningkatan terhadap resistensi pembuluh darah perifer dan juga penurunan perfusi organ. Salah satu teori etiologi preeklampsi yang dianut saat ini mengatakan adanya ketidakseimbangan antara produksi radikal bebas dan sistem pertahanan antioksidan yang menyebabkan timbulnya stres oksidatif, ditandai dengan adanya penurunan aktivitas antioksidan disertai dengan adanya peningkatan kadar lipid peroksida (oksidan / radikal bebas). Keadaan ini tentu saja menimbulkan terganggunya fungsi endotel bahkan rusaknya seluruh struktur sel endotel yang disebut sebagai disfungsi endotel. Keadaan stres oksidatif bisa dikendalikan dengan pemberian anti oksidan yang terbagi dalam antioksidan enzimatis dan non enzimatis. Antioksidan enzimatis terdiri dari superoksida dismutase (SOD), glutation peroksidase dan katalase. Buah delima mengandung fitokimia dan kaya akan senyawa yang berfungsi sebagai antioksidan yaitu polifenol, tanin dan anthocyanin. Tujuan penelitian ini adalah untuk mengetahui efek pemberian ekstrak buah delima merah merah (Punica granatum) terhadap kadar SOD dan MDA pada kultur HUVECs yang dipapar plasma preeklampsi.

Rancangan percobaan berupa rancangan acak lengkap dengan 5 kelompok perlakuan yaitu, Kelompok I : Kontrol negatif (K-) HUVECs + plasma kehamilan normal 2%, Kelompok II : Kontrol positif (K+) HUVECs + plasma preeklampsi 2%, Kelompok III : Perlakuan 1 (P1) HUVECs + plasma preeklampsi 2% + ekstrak buah delima merah 14 ppm, kelompok IV : Perlakuan 2 (P2) HUVECs + plasma preeklampsi 2% + ekstrak buah delima merah 28 ppm dan Kelompok V : Perlakuan 3 (P3) HUVECs + plasma preeklampsi 2% + ekstrak buah delima merah 56 ppm.

Berdasarkan pada hasil uji LSD 5 % menunjukkan bahwa kelompok kontrol negatif (K-) memiliki rata-rata kadar SOD berbeda nyata dengan kelompok kontrol positif (K+) (p = < 0,05). Peningkatan kadar SOD secara signifikan ditunjukkan oleh pemberian ekstrak buah delima merah pada konsentrasi 56 ppm. Bahkan, pemberian ekstrak buah delima merah konsentrasi 56 ppm mampu meningkatkan kadar SOD hingga lebih tinggi daripada kelompok kontrol negatif (p = < 0,05), sedangkan pemberian ekstrak buah delima merah pada dengan konsentrasi 14 ppm dan 28 ppm, belum mampu meningkatkan kadar SOD secara signifikan (p = > 0,05).

Sehingga dapat disimpulkan, bahwa pemberian ekstrak buah delima merah (Punica granatum) terbukti dapat meningkatkan kadar SOD pada kultur HUVECs yang dipapar plasma preeklampsi.

Authors: Büyükşimsek Mahmut , Oğul Ali
Published: April 2020

Objective: According to metastatic renal cell carcinoma treatment protocol, after the use of tyrosine kinase inhibitors (TKI) has been achieved significant improvements for the treatment of metastatic renal cell carcinoma (mRCC). In this study, we aimed to investigate the effect of neutrophil-to-lymphocyte ratio (NLR) and prognostic nutritional index (PNI) on survival in patients with mRCC treated with sunitinib or pazopanib.

Material and Methods: Medical data for 38 patients with mRCC were reviewed retrospectively. NLR and PNI values were dichotomized based on receiver operating characteristic (ROC) curve analysis (cut-off values: 3 and 46, respectively). Univariate and multivariate analyses were performed to identify prognostic factors for progression free survival (PFS) and overall survival (OS) using a Cox proportional hazards model.

Results: Median PFS and OS were 12 and 27 months, respectively. Median PFS was 10 months in patients with NLR ≥3 while 14 months in patients with NLR <3 (p: 0.008). Median OS was 18 months in patients with NLR ≥3 while 31 months in patients with NLR <3 (p: 0.003). In patients with PNI ≥ 46, PFS was 21 months and OS was 47 months whereas in patients with PNI < 46, PFS was 8 months and OS was 13 months (p values were <0.001, <0.001 respectively). In multivariate analysis, PNI was the independent risk factor for both PFS and OS, while NLR was the independent risk factor for OS only.

Conclusion: In patients with mRCC that using sunitinib or pazopanib, NLR and PNI values can be used as easily accessible prognostic markers.

Published: April 2020

The waste water which are the outcomes of processing liquids cannot be used further without proper treatment so the water has to be treated and handled in order to elude the contamination that deteriorates the quality of the atmosphere. Although the biological methods can be utilized for treating the wastes in the water by decomposing the bacteria, it is biased by various causes such as the impurity level, the oxygen available, the dirt type etc. But the standard methodology like aeration utilizes the biological and the chemical oxygen demand reduction termed BO and CO respectively to treat the waste water, the conventional aeration process is performed manually causing enormous usage of electrical energy. So the paper elaborates the scheme of a fuzzy logic based aerator control system (FLACS) for the waste water. The essential equipment of the proposed system are the sensors providing the particulars of the chemical and the biological oxygen demand as input, the microcontroller (Arduino UNO) and other electrical and electronic equipment’s that controls the working of the aerator. The analysis performed on the proffered model indicates the performance improvement of the FLACS in terms of the electrical energy utilization and duration of working hours.

#Covid-19 : Il faut repenser le rôle des revues scientifiques en management
Authors: Mamavi Olivier , Zerbib Romain
Published: April 2020

La crise inédite du COVID 19 agit à la fois comme un effet loupe et un accélérateur de particules. Les revues académiques, traditionnellement taxées de journaux "hors sol", sont plus que jamais remises en cause. Alors que les revues médicales apportent leur contribution à la résolution du problème épidémique, les revues en sciences de gestion ne se montrent pas aussi efficaces pour résoudre les enjeux brûlants que vivent actuellement les entreprises (décroissance, pénuries, transformation digitale, etc.). Si les revues en sciences de gestion ne constituent pas des interlocuteurs aussi légitimes, au sujet du management, que les revues médicales en matière sanitaire, alors à quoi pourraient-elles bien servir ?

Common Ground
Authors: Häfner Lukas
Published: April 2020

Die im Jahr 2020 in Deutschland praktizierte Siedlungs- und Wohnungspolitik erhält in Anbetracht ihrer Auswirkungen auf die soziale und ökologische Lage einen bitteren Beigeschmack. Arm und Reich driften weiter auseinander und einer zielgerichteten ökologischen Transformation der Art und Weise, wie Stadtentwicklung und Wohnungspolitik gestaltet werden, stehen noch immer historisch und systemisch bedingte Pfadabhängigkeiten im Weg. Diese werden nur durch eine integrierte Betrachtung sozialer und ökonomischer Aspekte sichtbar und deuten auf eine der ursprünglichen Fragen linker Gesellschaftsforschung hin: Die Auseinandersetzung mit dem Verhältnis von Eigentum und Gerechtigkeit.

Im Ergebnis stehen drei wesentliche Befunde: Der Diskurs zum Schutz des Klimas und der Biodiversität berührt direkt die Parameter Dichte, Nutzungsmischung und Flächeninanspruchnahme; zweitens steigt letztere relativ zu erhöhtem, individuell verfügbarem Kapital und insbesondere im selbstgenutzten Eigentum gegenüber Mietwohnungen; und drittens wächst der Eigentumsanteil mit fortschreitender Finanzialisierung des Wohnungsmarktes, sodass das Risiko sozialer und ökologischer Krisen sich verschärft.
Dachgärten im Geschosswohnbau

Published: April 2020

Der Trend zur Urbanisierung und Verdichtung von Wohnraum in Kombination mit der globalen Erwärmung zeigt immer deutlichere Auswirkungen auf das Stadtklima. Zur Reduktion der Belastungen für die Stadtbevölkerung sind gebäudegebundene Begrünungsformen eine wirksame Strategie. Vor allem die Verlagerung der Vegetation auf die bisher kaum genutzte Dachebene hat das Potenzial, negative Auswirkungen der Flächenversieglung und Flächenkonkurrenz auszugleichen, da intensive Dachbegrünungen vielfältige soziale, ökologische und ökonomische Vorteile haben. Da diese in der täglichen Planungs- und Wohnbaupraxis noch unzureichend genutzt werden, wurde in der Stadt Graz ein transformativer Kommunikations- und Lernprozess initiiert, der unter den beteiligten Akteuren nachhaltige Handlungsänderungen anregen soll. Dazu wurde auf Basis einer qualitativen Potenzialanalyse eine Dialogplattform ins Leben gerufen, die im Rahmen von interaktiven Workshop-Formaten relevante Stakeholder vernetzt hat. Dabei konnten Vorbehalte ausgeräumt, Erfahrungen ausgetauscht und Synergieeffekte ausgelotet werden. Durch die gemeinsame Konzeption von Demonstrationsprojekten soll das Erfahren, Experimentieren und Reflektieren mit innovativen Dachbegrünungen weiter angeregt werden. Dieser kontinuierliche Aushandlungs- und Lernprozess soll dazu beitragen, dass sich Dachgärten als wirksamer Lösungsansatz für die sozial-ökologischen Herausforderungen des modernen Wohn- und Städtebaus etablieren und weitere Nachhaltigkeitstransformationen gefördert werden.
Eine Frage der Flächengerechtigkeit!
Authors: Brokow-Loga Anton , Neßler Miriam
Published: April 2020

Die derzeitige Wohnungskrise hat eine sozial-ökologische Kernproblematik. Dabei ist die sozial ungerechte und ökologisch problematische Verteilung von Wohnfläche meist unsichtbar und wird weder in wissenschaftlichen noch in aktivistischen Kontexten ausreichend als Frage der Flächengerechtigkeit problematisiert. Denn Wohnraum und Fläche in einer Stadt sind keine endlos verfügbaren Güter: Wenn einige Menschen auf viel Raum leben, bleibt für andere Menschen weniger Fläche übrig. Und die Menschen, die am wenigstens für eine Verknappung von Wohnraum verantwortlich sind, leiden am meisten darunter. Dieser Artikel arbeitet zunächst den Begriff der Wohnflächengerechtigkeit heraus, wobei auf die Ungleichverteilung von Wohnfläche und deren gesellschaftliche Implikationen unter derzeitigen Wohnungsverteilungsmechanismen Bezug genommen wird. Anschließend wird der Verbrauch von (Wohn-)Fläche aus ökologischer Perspektive problematisiert. Der Artikel diskutiert scheinbare und transformationsorientierte Lösungs- und Handlungsansätze. Abschließend fordert er in der kritischen Stadtforschung und in aktivistischen Kontexten eine stärkere Debatte um eine Wohnflächengerechtigkeit, deren Verwirklichung gleichermaßen eine soziale wie ökologische Dimension hat.

Published: April 2020

Umkämpftes Grün. Zwischen neoliberaler Stadtentwicklung und Stadtgestaltung von unten von Sarah Kumnig, Marit Rosol und Andrea*s Exner eröffnet einen alternativen Blickwinkel auf die kritische Praxis des städtischen Gärtnerns. Die Gegenüberstellung verschiedener Maßstabsebenen, Fallbeispielen und Betrachtungsweisen, die von historischer Analyse bis zu Aktivismus vor Ort reichen, verdeutlichen die Ambivalenz des Phänomens ‚Urban Gardening‘ und legt Mechanismen und Effekte offen, die diese kritische Praxis der Raumaneignung in ihr Gegenteil verkehren können. Vor allem die Entkoppelung von Sozial- und Künstlerkritik führt zu einer programmatischen Schwächung der Initiativen und zu deren Vereinnahmung durch neoliberale Stadtpolitiken.
Urbane Kleingärten im Fokus von Stadtentwicklung
Authors: Thomas Nicola
Published: April 2020

Kleingärten in verdichteten europäischen Städten sind zunehmend Druck ausgesetzt, ihre Existenz und ihr Nutzungsrecht gegenüber alternativen Ansprüchen zu legitimieren. Als Problem wird dabei artikuliert, dass sich die Kleingartenareale auf städtischem Boden befinden und damit ein grünes Allgemeingut darstellen, allerdings nur von einer begrenzten Anzahl von Pächter_innen genutzt werden. Damit wird eine private Nutzung auf öffentlichem Land postuliert. Aufbauend auf einer qualitativen Untersuchung zu Kleingartenumnutzungen in Hamburg und Basel und dem Wertordnungskonzept des Soziologen Laurent Thévenot, argumentiert der Aufsatz für die Begrenztheit dieser Sichtweise. Stattdessen werden Kleingärten als spezifischer grüner Stadtraum, der zwischen privaten und öffentlichen Grenzziehungen zu verorten ist und vielfältige Bezüge erlaubt, konzeptualisiert. Der Artikel folgert, dass Planungskonflikte um Kleingärten Ausdruck der Übersetzungen von persönlichen Raumbezügen in ein politisches issue sind und als Verhandlungen eines mehrschichtigen Raumes als commons zu verstehen sind.
Quality of bio-solids produced in a Spanish Wastewater Treatment Plant (Córdoba-Spain) and its use in agronomy along 2000-2019
Authors: Galvín Rafael Marín
Published: April 2020

Bio-solids are the final fate of pollution present in urban wastewater, reaching the production of these ones in Spanish WWTPs 701,751 T/year (dates of 2018). Considering that 85% of Spanish bio-solids are used in agronomy, it is important to know characteristics of biosolids there produced, and in this way, we have investigated bio-solids generated in La Golondrina´s WWTP (Córdoba, Spain) along 2000-2019. This WWTP is a conventional facility operated by activated sludges (26.55x106 m3/year treated) which has produced 1.43 kg of bio-solids per m3 of treated wastewater (38.000 T/year). Our results indicated that bio-solids had a dryness over initial mass of 22.3%, and 74.9% of organic matter over dried matter (o.d.m.). At the same time, major components detected in bio-solids were N, P and Ca which levels were 5.0%, 3.5% and 3.7%, respectively. On the other hand, concentration of total metals in bio-solids ranged 13,024 mg/kg o.d.m., being the main metal Fe (11.749 mg/kg o.d.m.) followed by Zn, Cu and Mn, with levels as mg/kg o.d.m. of 463.1, 392.8 and 265.7, respectively. Evolution per year of all the investigated parameters are shown in the paper. Taking into account the use of bio-solids in agronomy, we have evaluated levels of metals limited by the Spanish normative to this respect: thus, the seven metals restricted (Cd, Cu, Ni, Pb, Zn, Hg and Cr) exhibited concentration in bio-solids very lower than parametric values established. Moreover, we have estimated the ratios of accumulation of organics and metals from wastewater to bio-solids: thus, organic matter, N and P, were accumulated in bio-solids respectively, 342, 356 and 643 times, and total metals, 2,632 times. Finally, levels of Escherichia coli slightly varied from wastewater to bio-solids: 1.5x108 colony-forming units/L in the first one, and 0.9x108/g (o.d.m.) in the second ones.

In this study made prebiotic from bioconversion of corn flour (Zea mays L.) by yeast Endomycopsis fibuligera as an alternative substitute for antibiotics. In this study, the addition of Na+, K+, Ca2+, and Mg2+ ions aimed to determine the optimum type and concentration of metal in prebiotic and testing the effect of prebiotic compounds produced on broiler weight gain. The analysis carried out included: reducing sugars, α-amylase and glucoamylase enzyme activity, protein content and cell biomass. To determine the existence of a significant effect, the analysis was carried out on broiler body weight given prebiotic compounds which were added to optimum metal ions and which were given prebiotic compounds without the addition of metal ions. The results showed that the addition of optimum metal ions was obtained on Ca2+ ions with a concentration of 0.25%, where the reducing sugar content of 0.600 mg / mL, the activity of the enzyme α-amylase and glucoamylase 0.519 and 0.287 units / mL, protein content 2.724 mg / mL, cell biomass 10.8933 mg / mL, from observations and statistical tests carried out by giving prebotic compounds by adding metal ions and giving prebiotic compounds without adding metal ions influence broiler weight gain with an average weight difference of 261 grams or 15% on day 30.

Graphene merupakan material 2 dimensional yang mempunyai sifat unik salah satunya memiliki luas permukaan sangat tinggi (~2630 m2g-1) yang dapat mengadsorbsi gas target. Tidak seperti sensor gas lainnya, sensor graphene dapat dioperasikan di bawah kondisi sekitar dan pada suhu kamar. Interaksi antar gas metanol dengan graphene menghasilkan perubahan pada sifak konduktifitas dan resistensinya yang membuat graphene menjadi elemen sensor yang baik. Struktur dan sifat elektronik graphene tergantung pada proses sintesisnya. Metode Hummers dan microwave irradiation dipilih karena biaya produksi efektif, menghasilkan graphene dengan sensitifitas tinggi terhadap target gas. Dari ketiga variasi pembuatan graphene dari Graphene Oxide (GO) melalui microwave irradiation yaitu 0,1 g-450 Watt, 0,1 g-630 Watt dan 0,02 g-450 Watt menunjukkan sensitifitas paling tinggi pada variasi graphene 0,02 g-450 Watt. Hal ini mengindikasikan semakin kecil massa GO  dan semakin tinggi daya microwave membentuk sifat graphene yang lebih optimal terlebih untuk sensor gas.

Geothermal energy depends on volcanic regions or plate subduction. Indonesia has geothermal potential due to the meeting of 3 (three) large plates. North Sulawesi is one of the areas located in the ring of fire. Some areas in the Minahasa Regency, North Sulawesi province, were targeted for research because they have manifestations of geothermal such as hot pools, steaming ground, mud pools, and other manifestations. The research location is divided into 3 (three) locations around the Lahendong geothermal area, namely the Lahendong pine forest, the Toraget hot air area, and the hot springs in the village of Totolan. The results of sample and ploting tests in ternary diagrams show that all three geothermal manifestations have sulfuric acid type fluids. This type of geothermal fluid has a high SO4 content, while HCO3 and Cl values ​​are low. Hot springs that have a type of sulfuric acid occur in active volcanic regions. This is supported by the lithology of three areas of manifestation which are composed of basalt resulting from volcanic rocks.

Authors: Siwek Tadeusz
Published: April 2020

The paper deals with an evaluation of geography by Czech geographers themselves. In the spring of 2007, a survey was conducted among 40 geographers from Czech universities. The research sought to discover how Czech geographers at various universities think of their field and what they hope to achieve for it, within the first decade of the 21st century. Each segment of the questionnaire was compared with the results of similar Polish research published some years ago. The answers of Czech geographers were similar to their Polish colleagues and it is evident that the results are significant in spite of a few respondents.

Published: April 2020

Este artigo apresenta o resultado da investigação realizada no Curso de Qualificação em Auxiliar Administrativo, Proeja, Câmpus Iporá, do Instituto Federal de Educação, Ciência e Tecnologia Goiano. A pesquisa teve como foco investigar se a evasão ocorrida no referido curso estava relacionada, dentre outros fatores, com o ensino de Matemática. A metodologia aplicada foi de natureza qualitativa. O tipo de pesquisa foi o estudo de caso, quanto aos objetivos, exploratória. Realizou-se a coleta de dados por meio de aplicação de questionários semiestruturados e entrevistas com gravação em áudio.  Observou-se nas respostas que a evasão escolar, além das questões de ordem socioeconômicas, tem-se as dificuldades no processo ensino-aprendizagem. Os dados indicaram fatores intra e extraescolares que contribuem na decisão de evasão escolar. A disciplina de Matemática, que é o foco dessa análise, não se confirmou como um fator relevante na decisão do aluno em evadir-se do curso. Identificou-se dificuldades no processo ensino-aprendizagem e falta de formação pedagógica específica para os professores da EJA. Acredita-se que esta pesquisa tem relevância social por abordar a questão da evasão como sendo um termômetro que indica a necessidade de ação política e escolar, para que o sujeito da EJA se aproprie de uma educação emancipadora.

Published: April 2020

Non-severe hypothyroidism has no strong association with hyponatremia. However, thyroid function tests (TFT) continue to be ordered as a first-line investigation. The objective of this study was to establish the prevalence of inpatient hyponatremia and to reiterate the association between thyroid disorders and hyponatremia based on study findings and current literature. A cross-sectional study on 3,478 in-patients adults of both gender admitted to a Malaysian tertiary hospital was carried out.  Age, gender, sodium levels, thyroid stimulating hormone (TSH), free thyroxine (fT4) and clinical notes between 1/11/17-31/12/17 were extracted from the hospital’s information system. Bivariate analysis was performed using Mann-Whitney U, Chi-square and Spearman correlation tests. 21.9% of inpatients had hyponatremia of which 52% were mild. 359 (69%) of hyponatremic patients had a TFT sent where 71.9% were euthyroid. Sodium level is significantly correlated with age (R=-0.257, P<0.001). No correlations were found between sodium and TSH and fT4. Sodium was significantly lower in the non-thyroidal illness (NTI) group compared to the hypothyroid group. No significant differences in sodium were found between the hypothyroid group and other thyroid states. Hence it was conclude that in hyponatremia, TFT is indicated when there is clinical evidence of severe hypothyroidism, suspicion of hypothalamus-pituitary-axis disorder or when no cause of SIADH is apparent. Otherwise, TFT is unnecessary and costly as a first-line investigation.

Betel quid chewing is a detrimental recreational habit amongst Asians and a risk factor for oral cancer. Arecoline, a component of areca nut (a major constituent of betel quid) is a known carcinogen. However, the effect of areca nut crude extract is not much studied. To evaluate the cytotoxicity and morphologic effects of areca nut aqueous extract on mouse fibroblast cell line (L929). Dried raw areca nut obtained from a local market in Kota Bharu, Kelantan was prepared and suspended in DMEM (Dulbecco’s Modified Eagle’s medium), prior to serial dilution of 1.56, 0.781, 0.39, 0.195, 0.0976, 0.0488, and 0.0244 mg/ml. The L929 was then exposed to each of the aqueous areca nut extract dilutions and incubated at 37 °C for 24, 48 and 72 hours. Following incubation, the cytotoxicity level of treated L929 was measured using MTT [3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium] assay. Five highest concentrations of areca nut extract showed significantly decreased L929 cell viability (1.56, 0.781, 0.39, 0.195, 0.0976 mg/ml) for all incubation periods compared to untreated cells (p<0.05). The IC50 values of aqueous areca nut extract on L929 were 0.1516, 0.1040, and 0.09136 mg/ml at 24, 48 and 72 hours, respectively. The L929 cell showed altered morphology when cultured in the extract for 24 hours. Higher concentrations of the areca nut aqueous extract is cytotoxic to L929. Prolonged exposure to the extract reduced the IC50 value. Investigation on the role of areca nut in cell proliferation could be further undertaken to assess its association with oral cancer.
