Abstract

Tujuan dari penelitian ini adalah untuk mengetahui pengaruh terapi suplementasi fitosterol pada profil lemak, kadar apolipoprotein B-48, dan mengetahui jumlah sel busa pada tikus pasca diet atherogenik. Penelitian ini dilakukan menggunakan tikus wistar (34 ekor), umur 6-8 minggu, berat 100-160 g, diperlakukan diet atherogenik selama 8 minggu, dilanjutkan dengan diet standar (n=5), diet standar dengan suplementasi tablet fitosterol 0,1% (n=5), 1% (n=6), dan 2% (n=6) dalam total makanan selama 6 minggu. Tikus diet standar 14 minggu sebagai kontrol negatif (n=5) dan tikus diet atherogenik 14 minggu sebagai kontrol positif (n=6). Profil lemak (Kolesterol Total, Trigliserida dan HDL-Kolesterol) dianalisis dengan kit (Diasys), kadar LDL-kolesterol dihitung dengan rumus friedwall sedangkan kadar non HDL-kolesterol dihitung dengan mengurangi kadar kolesterol total dengan kadar HDL-Kolesterol. Kadar Apo-B-48 dianalisis dengan elektroforesis, elektroelusi, dialisa dan spektrofotometri diuret atau laury. Perhitungan jumlah sel busa aorta dilakukan secara manual pada 20 lapangan pandang pembesaran 1000X setelah pewarnaan dengan Oil Red O dan Hematoxilin-Eosin (HE) dengan 3 kali pengulangan. Hasil suplementasi fitosterol dosis 0,1% memiliki rentang 40-50 mg/kgBB/hari, 421-521 mg/kgBB/hari pada dosis 1% dan 937-1250 mg/kgBB/hari pada dosis 2%. Perbedaan signifikan didapatkan pada kadar kolesterol total, LDL-kolesterol, dan non HDL-kolesterol antara kontrol dengan kelompok suplementasi. Kadar HDL-Kolesterol secara signifikan lebih rendah sedangkan kadar ApoB-48 tidak dapat dikuantifikasi akibat berbagai sebab. Penghitungan sel busa pun berbeda nyata antara kontrol dengan suplementasi. Beradsarkan penelitian ini diketahui bahwa suplementasi fitosterol dalam diet memiliki efek terapetik pada profil lemak (kolesterol total, LDL-kolesterol, dan non HDL kolesterol) sehingga mampu mengurangi jumlah sel busa aorta tikus pasca diet atherogenik.

Abstract

The emergence of Java and Sumatra islands at the end of Miocene, has impact to the diversity of fauna that living in the islands. Amphibia, as one of a genetic information series, can be used as a good phylogenetic comparison. Genus Megophrys (Anura: Megophryidae), is a member of amphibians that live isolated at an altitude of 1000 ASL (Above Sea Level) or more. The purpose of this research is to analyze the phylogenetic patterns of genus Megophrys in Java and Sumatra based on the analysis of 16s rRNA gene. We also analyzed the zoogeography to understand the history of relationship and the establishment of these islands. We took samples on 12 localities: 10 areas of Sumatra and 2 areas of Java. We used Qiamp Blood and Tissue Kit to extract the DNA from tissues. Qualitative analysis of DNA was done by running electrophoresis on 1% agarose gel. Qualitative analysis of DNA was done by running electrophoresis on 1% agarose gel. Results show that Clade A has 2 subclasses: I and II. Subclade I consists of Sumatran specimens, whereas subclade II consists of Javanese specimens. Subclaude I and II have paraphyletic connections. Clade B classified as politomy clade consists of Megophrys sp. from West Pasaman, Megophrys sp. from West Sumatra and Megophrys sp. from Pasawaran, Lampung. The result shows that Megophrys sp. of subclade I (clade A) and clade B, belongs to the same group, both of them were originated from Sumatra. Megophrys sp. subclade I (clade A) originated from Tanggamus (Lampung) and West Lampung (Lampung) separated with 2 species of Megophrys sp. of clade B originated from Pasawaran (Lampung).Keywords: 16s rRNA, Java, Megohprys, Sumatra, zoogeography

Abstract

Calcium crystal accumulation on kidney can cause kidney stone (nephrolithiasis). The oxalate calcium crystal which is deposite on the kidney can trigger inflammation on the epithelial that is able to induce cells death (necrosis). The necrosis is able to cause inflammation and it will affect the body's immune system. Infection agent that comes to the body will be responded by the innate immunity which will be responded later by adaptive immunity. One of herbal agent that is expected to be used to stimulate adaptive immunity response is Tempuyung (Sonchus arvensis) leaf extract. The aim of this study is to find out the change of relative amount of CD4+ T cells, CD8+ T cells, and B (B220) cells on nephrolithiasis mice model after S.arvensis leaf extract. The mice are divided into six groups; control group, placebo, nephrolithiasis, S.arvensis leaf extract for 7 days, nephrolithiasis then it is continued with S.arvensis leaf extract for 7 days, and simultaneous (nephrolithiasis and S.arvensis leaf extract for 3 months). The amount of relative T lymphocyte cells is measured by using BD FACSCalibur FlowcytometerTM. The data is analyzed by using ANOVA one way (p<0.05) using SPSS 16.0 software for Windows. The result shows that there are changes of relative CD4+ T cells, CD8+ T cells, and B (B220) cells on nephrolithiasis mice model after the giving of S.arvensis leaf extract. The treatment of S.arvensis leaf extract on the nephrolithiasis mice model can stimulate the homeostatic activity by suppressing the B cells. Compound of S.arvensis leaf extract that can inhibit of Th1 cells and the increase of Th2 cells by proliferation cells activity. The treatment of S.arvensis leaf extract for 7 days can suppress CD4+.

Abstract

Detection of porcine contamination in food material by employing PCR techniques is integral in halal food confirmation. However, PCR is both costly and laborious, particularly in DNA isolation method. This study explores several different methods in DNA extraction for PCR amplification in bovine and porcine raw and boiled meat samples. Four methods for DNA extraction (conventional PCI method, DNA isolation kit, alkaline-based method, and a DNA lysis buffer-only from the same kit) was employed followed by PCR using primers from previous studies and compared for DNA quality and quantity (in six replicates) and PCR amplification on the best three DNA samples. This study shows that in all samples, the conventional method had the best DNA yield based on nanodrop measurement, followed by an alkali-based method, buffer-only method, and DNA isolation kit. Each method except lysis-buffer only had at least one sample with good DNA quality. Conventional and isolation kit showed reliable positive PCR detection for all porcine and bovine samples (92% positive). Using the alkaline-lysis method, DNA was amplified reliably on boiled meat samples (83% positive). Lysis-buffer-only method did not show consistent PCR amplification on the samples used (50% positive). The conclusion was that conventional PCI method and DNA isolation kit showed high reliability in PCR amplification of bovine and porcine meats, both raw and boiled. While high DNA yield was obtained using the alkaline-lysis method, PCR amplification was only successful on boiled samples. Lysis-buffer only method yielded in poor DNA quality and was not able to result in reliable DNA amplification.Keywords: DNA extraction methods, halal, Porcine food contaminants.

Abstract

Myxobolus koi is a type of parasite that infects many freshwater fish through myxospores, resulting in a disease called myxobolosis. This research aimed is to investigate the clinical symptoms that occur in the gills of infected Koi carp (C. carpio). The utilized methods in this study are molecular detection, histopathology, and Scanning Electron Microscopy (SEM). Koi carp samples that are suspected to be infected with Myxobolus koi show several clinical signs, such as swollen and pale-colored gills and gill covers (opercula) that do not close completely, as well as white spots that appear on the edge of the lamella. The results of this study showed that through histological observations, there were changes characterized by hyperplasia of the primary lamella cartilage that envelops parasitic cysts and the encapsulation process that surrounds the cysts by gill cartilage in infected fish;SEM showed oval and elongated spores of a size of ± 12 µm (800x). TheDNA template from gill tissues in clinically infected and uninfected fish was examined byPCR testing with primers ERB 1 (Forward) and ERB 10 (Reverse); the results of electrophoresis in infected fish were detected at 2000 bp. Keywords: Cyprinus carpio, Histopathology, Molecular Detection, Myxobolus koi, Parasite, SEM.
