Abstract

Tuberkulosis adalah penyakit infeksi menular, kronik dan dapat menyebabkan kematian yang disebabkan oleh Mycobacterium tuberculosis. Diagnosa tuberkulosis dilakukan dengan berbagai cara, salah satunya dengan kultur pada media Ogawa. Penelitian ini bertujuan untuk mengetahui kecepatan pertumbuhan M. tuberculosis pada media ogawa dengan bahan dasar telur puyuh, telur bebek, telur enthok, dan telur ayam kampung. Metode yang dilakukan yaitu sputum BTA 3+ yang didapatkan dari Balai Kesehatan Paru Masyarakat (BKPM) Semarang diolah dengan metode kubica, kemudian diinokulasi pada media ogawa dengan bahan dasar telur yang berbeda. Pengamatan kecepatan pertumbuham M. tuberculosis dilakukan setiap hari. Hasil penelitian menunjukan ada perbedaan yang signifikan pada ke empat telur terhadap pertumbuhan M. tuberculosis pada media ogawa. Hasil penelitian menunjukkan bahwa media ogawa dengan bahan dasar telur puyuh dan entok dapat menumbuhkan M. tuberculosis lebih cepat dibanding dengan bahan dasar telur ayam kampung dan telur bebek. Media ogawa berbahan dasar telur puyuh dan telur entok menunjukkan rata-rata waktu pertumbuhan tercepat yaitu 17 hari. Sedangkan bahan dasar telur ayam kampung 20-21 hari dan bahan dasar telur bebek 23-24 hari.

Abstract. The purposes of this research are for molecular characterization and hemagglutination activity test of flagellinprotein of Salmonella typhi. The research samples consist of 7 strains of S. typhi isolates from Central Java (5 strains from Semarang city, 1 strain from Salatiga and 1 strain from Magelang) and 2 strains of S. typhi from Yogyakarta (Doctor Sardjito Hospital and Bethesda Hospital). The undertaking procedures are: 1) PCR and sequencing of fliC genes using primer LPW 1856 and LPW 1857.2) Isolation and separation of flagellin protein using SDS-PAGE. 3) Hemagglutination Activity Test upon human erythrocytes of blood group A, B, AB and O.The results show that 8 strains of S. typhi have a fliC gene size of 1452 to 1488 bp including serovar H1-d, and 1 strain with the size of 1267 bp including serovar H1-J. Flagella protein resulted from SDS-PAGE protein consists of 1-2 major proteins and 1-3 minor proteins with a molecular weight of 16-116 kDa. The results of hemagglutination activity test of flagellin protein show that there are 3 strains of S. typhi (MG-1, SA02.2 and BET) which are able to agglutinate human erythrocytes of bloodgroup A, B, AB and O (2-64HA), 6 other strains show various hemagglutination activities varied

Abstract

This study aimed to analyze the antibacterial activity of Palm oil Honey against Multi  Drug  Resistant  Salmonella  typhi  and  Methicillin-Resistant Staphylococcus aureus by concentration 50%, 60%, 70%, 80%, 90% and 100%. This  research  was  an  experimental  test  with  Posttest  Only  Control  Group Design in an in vitro manner using well diffusion method techniques. The well diffusion method used MHA which made by the well of 5 mm diameter and inserted 200 µ L sample then incubated 35 ± 20C for 24 hours. The results of the study showed the antibacterial activity of Palm oil Honey with zone inhibition against MDR S.typhi 11.4 mm (concentration 90%), 13.4 mm (concentration 100%) and against MRSA 11.7 mm (concentration 100%). The results of zone inhibition of Palm oil honey with concentration 100% against MDR S.typhi was larger than the  zone inhibition  against MRSA. The palm oil honey inhibition zone  against  S.typhi  MDR  bacteria  compared  with  sulfamethoxazole  (SXT) antibiotics with 25 mm inhibition zones was included in the intermediate category and the palm oil honey inhibition zone against MRSA bacteria compared with Tetracycline (TE) antibiotics with 23 mm inhibition zone was included in resistant category. Keywords: Antibacterial Activity, MDR S. typhi, MRSA, Honey, Inhibition Zone

Abstract

Black rice is a food crop with black pigments, which helps reduce the risk of various diseases and improve health. One way to improve food quality and avoid food contaminants is by irradiating. This study evaluated the phytochemical profile, antioxidant activity, and anticancer activity of irradiated black rice bran extract (IBRBE) in vitro and in silico. Black rice was irradiated with a Gamma cell 220 type irradiator at a 7.5 kGy/hour dose rate. Extraction of irradiated black rice bran was carried out using the maceration method. Phenolic and flavonoid components were quantified using the Folin–Ciocalteau and AlCl3 methods, respectively. Phytochemical compounds were identified by liquid chromatography-high-resolution mass spectrometry (LC HRMS). The antioxidant activity of IBRBE was carried out against 2,2-diphenyl-1picrylhydazyl (DPPH). The cytotoxic activity of IBRBE against WiDr cells (colorectal cancer) and Vero (nonhuman cell lines) used the MT test method. Prediction of the inhibitory mechanism of compounds in the extract against target proteins EGFR and GPX7 was carried out in silico. Total phenolics and flavonoids were 2.57 ± 0.28 mg GAE/g and 19.12 ± 0.18 μg QE/ml, respectively. Twenty-four types of active compounds were obtained in IBRBE. The results of antioxidant activity obtained an IC50 value of 1198.45 ± 92.86 μg/ml. IC50 in WiDr cells and Vero cells were obtained at 36.08 ± 11.71 μg/ml and 570.58 ± 130.25 μg/ml, respectively. In silico results, the compound 4 Dodecylbenzene sulfonic acid has the highest binding affinity to the EGFR protein, with a value of -5.9. Meanwhile, the Monoolein compound has the highest binding affinity to the GPX7 protein, with a value of -5.4.
