Abstract

The hijau (Camellia sinensis) memiliki beragam efek farmakologik, di antaranya sebagai antibakteri. Salmonella typhi penyebab demam tifoid, masih merupakan masalah kesehatan masyarakat di negara tropis terdapat 20 juta kasus dan 600.000 kematian per tahun di seluruh dunia. Penelitian ini ingin mengetahui daya antibakteri dan lamanya waktu kontak infusa teh hijau dari berbagai merek kemasan terhadap Salmonella typhi secara in vitro dengan menggunakan teknik difusi sumur, selanjutnya data dianalisis dengan ANAVA dan uji t-independen. Penelitian dilakukan di Laboratorium Mikrobiologi Fakultas Kedokteran Universitas Padjadjaran, Bandung pada bulan Maret-April 2009. Hasil menunjukkan infusa dengan konsentrasi 40% (b/v) kemasan komersial Indonesia memberikan rata-rata diameter daerah hambat 3,376±0,334 mm dan 3,571± 0,217 mm pada kemasan Jepang (p<0,05); 0,707±0,000 mm pada konsentrasi di bawah 40% rata-rata daerah hambat. Tidak terdapat perbedaan antara kemasan Indonesia dan Jepang (p>0,551). Terdapat kekeruhan pada media cair Muller-Hinton dibandingkan dengan media kontrol pada konsentrasi di bawah 40% Teramatinya pertumbuhan koloni S. typhi pada agar Muller-Hinton konsentrasi 5% dan 10%. Tidak teramati penurunan jumlah koloni S. typhi konsentrasi kurang atau sama dengan 40% pada pengamatan waktu kontak 0 sampai 60 menit (p>0,05; á=0,05). Kesimpulan menunjukkan teramatinya daya antibakteri infusa teh hijau pada kemasan dengan konsentrasi 40%. Belum teramatinya daya antibakteri infusa dan pengaruh waktu kontak positif pada reduksi pertumbuhan koloni S. typhi pada kemasan dengan konsentrasi di bawah 40%.Antibacterial Activities and Time Contact Green Tea Infussion (Camellia Sinensis) Againsts Salmonella Typhi by In VitroGreen tea (Camellia sinensis) contains cathecin which has been reported to have various pharmacologic properties, such as an antibacterial agent. Salmonella typhi, as agent of typhoid fever, remains a public health problem in tropical countries; about 20 million cases and 600.000 deaths annually all over the world. Objectives of this research were to observe the antibacterial activities and contact time of green tea infusion againsts Salmonella typhi by in vitro experiment. The experiment took place in Microbiology Laboratory, School of Medicine, Padjadjaran University, Bandung, March-April 2009. Methods: In vitro laboratory analytic study has been conducted on green tea infusion of Indonesian and Japanese commercial package againsts Salmonella typhi.

Abstract

Methicillin resistant Staphylococcus aureus (MRSA) merupakan salah satu galur multiresisten yang menjadi masalah kesehatan global sejak 50 tahun terakhir. Secara genetik, resistensi MRSA didasari adanya insersi mecDNA atau Staphylococcal cassette chromosome mec (SCCmec) pada kromosom S. aureus. Sejauh ini telah diidentifikasi 5 tipe SCCmec, yaitu SCCmec tipe I–V yang berasal dari isolat di seluruh dunia. Akhir-akhir ini ditemukan perubahan pola penyebaran, pola kepekaan terhadap antimikrob, dan perubahan kandungan SCCmec. Oleh karena itu identifikasi SCCmec menjadi demikian penting untuk mengetahui adanya perubahan tersebut. Tujuan penelitian ini adalah untuk mengidentifikasi tipe SCCmec dari isolat MRSA yang diperoleh di rumah sakit. Penelitian dilakukan di Laboratorium Mikrobiologi Klinik RSUP Moh. Hoesin Palembang dalam rentang waktu Oktober 2008–Maret 2009. Metode yang digunakan untuk mengidentifikasi SCCmec tersebut adalah metode polymerase chain reaction (PCR) multipleks. Hasil penelitian menunjukkan bahwa 33 isolat (83%) memiliki SCCmec tipe III dan 7 isolat (17%) memiliki SCCmec tipe IV. Hasil ini berbeda dengan penelitian sebelumnya yang menemukan 100% MRSA di Indonesia memiliki SCCmec tipe III. Kesimpulan dari penelitian ini adalah teridentifikasi adanya perubahan kandungan SCCmec pada isolat MRSA yang berasal dari rumah sakit. [MKB. 2011;43(2):60–5].Kata kunci: Methicillin resistant Staphylococcus aureus, polymerase chain reaction, SCCmecIdentification of Staphylococcal Cassette Chromosome Mec Methicillin Resistant Staphylococcus aureus Using Polymerase Chain ReactionMethicillin resistant Staphylococcus aureus (MRSA) is one of multiresistant strain that becomes global health problem during 50 years. Resistance of MRSA is based on insertion mobile genetic element mecDNA or Staphylococcal cassette chromosome mec (SCCmec) into chromosome of S. aureus. Researchers had been isolated five types of SCCmec-type i.e. I–V. During last ten years, researchers have been finding alteration of spreading pattern, susceptibility pattern, and content of SCCmec. Identification of SCCmec is important to elucidate these alterations. The aim of this research was to identify type of SCCmec from hospital isolates MRSA.We did the research in Moh. Hoesin General Hospital (RSUP MH) Palembang period October 2008 to March 2009. We used polymerase chain reaction (PCR) multiplex method to identify SCCmec. The result showed that 33 isolates (83%) having type III of SCCmec and 7 isolates (17%) having type IV of SCCmec. The results were different from other researcher’s founding that in Indonesia, all of MRSA have SCCmec.The conclusion of this research content of SCCmec from hospital isolates of MRSA has already been changed.

Abstract

AbstrakImunisasi pertusis yang hanya diberikan pada masa bayi tidak dapat memberikan proteksi jangka panjang, sehingga terjadi reemerging pertusis. Tujuan penelitian ini adalah untuk mengetahui hubungan usia remaja, dewasa, dan orang tua dengan titer IgG pertusis menggunakan metode enzyme linked immunosorbent assay (ELISA) dan mikroaglutinasi pertusis (MAP). Penelitian observasi analitik dengan rancangan potong lintang ini dilakukan pada 402 subjek yang terdiri atas 134 remaja (12–18 tahun), 187 dewasa (19–49 tahun), dan 81 orang tua (50–64 tahun) di kota Bandung periode 2008–2010. IgG pertusis ditentukan dengan metode ELISA dan MAP. IgG pertusis positif berdasarkan ELISA ditemukan berturut-turut pada 92 (68,7%) remaja, 143 (76,5%) dewasa, dan 72 (88,9%) orang tua (p=0,003). Menggunakan metode MAP persentase IgG pertusis positif pada usia remaja, dewasa, dan orang tua berturut-turut sebesar 27 (20,1%), 9 (4,8%), dan 3 (3,37%), terjadi penurunan dengan bertambahnya usia (p&lt;0,001), menunjukkan proteksi imunisasi tidak dapat bertahan lama. Bila sampel dengan MAP positif dikeluarkan untuk memperoleh titer IgG pertusis akibat infeksi pertusis alamiah maka diperoleh persentase IgG pertusis positif 68,9%. Simpulan, terdapat hubungan antara usia dan titer IgG pertusis positif pada populasi remaja, dewasa, dan orang tua di kota Bandung menggunakan metode ELISA dan MAP. Persentase IgG positif hasil pengukuran ELISA meningkat dengan semakin bertambahnya usia.

In some countries whooping cough became an reemerging disease. The objective of this study was to evaluate the correlation between age and percentage of positive IgG pertussis in adolescent, adult, and elderly population using enzyme link immunosorbent assay (ELISA) and microagglutination. This observational analytic with cross sectional study was done on 402 subjects, consisted of 134 adolescents (12–18 years), 187 adults (19–49 years), and 81 elderly (50–64 years) in Bandung, period 2008–2010. Titer of pertussis IgG was measured using ELISA and microagglutinationof pertussis (MAP). The ELISA results showed positive IgG pertussis in 92 (68.7%) adolescent, 143 (76.5%) adults, and 72 (88.9%) elderly (p=0.003). The results of MAP showed positive pertussis IgG in adolescent, adults, and elderly were 27 (20.1%), 9 (4.8%), and 3 (3.37%), respectively, which was decreased with age (p&lt;0.001).If MAP positive samples were excluded from the analysis in ELISA positive samples, which express the IgG pertussis due to contact with circulate B, the pertussis IgG positive was 68.9%. In conclusion, there is a correlation between age and percentage of positive IgG pertussis titer in adolescent, adult, and ederly population in Bandung using ELISA and MAP methods. Positive pertussis IgG by ELISA is increased with age. [MKB. 2011;43(1):10–5].Key words: Bordetella pertussis, enzyme linked immunosorbent assay, IgG, microagglutination

Abstract

Gastric Ulcer is a common side effect of Non-Steroid Anti Inflammatory Drugs (NSAIDs) use such as Aspirin. Probiotic has many benefits especially for the alimentary system, but the effect on gastric ulcer have yet to be explored. In this research we aimed to find the probiotic effect on histological structure changes during aspirin induced gastric ulcer healing process in animal model. This was simple random sampling animal experimental laboratory, that divided Wistar Rats into two main groups. Both groups were induced with Aspirin (300mg/Kg BW) per oral, once daily for three consecutive days,and subsequently the test group were given probiotic suspension (cfu &gt;108/gr) per oral, once daily, for 14 days. Each subgroups were sacrified serially at day 0, 3, 7, 14. The gaster were collected and processed for histology examination. Better histological structures were shown in the test group at day 14. MANOVA result showed probiotics effect in enhancing histological structure changes during gastric ulcer healing process. Better histological structure changes were observed in mucus thickness; reepitelization, gastric glands formation, and angiogenesis process of the test group. As a conclusion, probiotic enhanced mucus thickness, reepitelization, glands remodelling, and angiogenesis in Aspirin induced gastric ulcer healing process in animal model. Key words: probiotic, gastric ulcer, histological structure, aspirin, healing process

Abstract

Staphylococcus aureus (S.aureus) remains to be the most important cause of post operative wound infection. Nursescould become reservoirs to transmit S.aureus through contaminated hands transiently, or through colonized nose.Strain polymorphism could be determined by Restriction Fragment Length Polymorphism (RFLP), using coa gene andrestriction endonuclease enzyme Alu1. There were 30 isolates of S.aureus’s infection, and 20 isolates taken from handsand nose of the nurses in charge. From 50 isolate positive S.aureus, PCR results showed single and multiple bandswithin 300 to 900 base pairs (bp) in length, and multiple bands within 200 to 600 bp. Five out of 30 patients (17%)showed no PCR-RFLP similarity with any of the nurses. Ten out of 15 nurses which hands were positive for S.aureus,has PCR-RFLP similarity with some patients. There was only 1 out of 5 nurses which nose was positive for S.aureus,showed PCR-RFLP similarity with some patients. Statistically, the proportion of the similar PCR-RFLP between thosesamples in this study is 0.12 (12%). Conclusion: Nurses had 12 % PCR-RFLP similarity for S.aureus with post operativewound infection.

Abstract

Askariasis di daerah endemis seperti Indonesia menyebabkan polarisasi respons Th2 yang dapat menekan respons Th1 yang penting dalam perlawanan terhadap tuberkulosis melalui penekanan ekspresi IL-12Rẞ2 oleh IL-4. Tujuan penelitian ini adalah mencari hubungan antara kejadian askariasis dan tuberkulosis aktif di daerah endemis rendah askariasis. Penelitian observasional analitik dilakukan pada 30 penderita dewasa tuberkulosis paru aktif baru dan 29 penderita tuberkulosis laten. Penelitian dilaksanakan di Kota Bandung selama periode April–Juni 2014. Pemeriksaan telur Ascaris lumbricoides dilakukan dengan teknik Kato-Katz smear dan pengukuran kadar reseptor terlarut IL-12Rẞ2 dalam plasma mengunakan metode enzyme linked immunosorbent assay (ELISA). Hasil penelitian menunjukkan proporsi askariasis pada penderita tuberkulosis aktif secara signifikan lebih rendah (5 dari 30 subjek) dari proporsi askariasis pada penderita tuberkulosis laten (13 dari 29 subjek) dengan p=0,019. Penghitungan jumlah telur menunjukkan semua subjek askariasis menderita askariasis intensitas ringan. Kadar reseptor terlarut IL-12Rẞ2 pada penderita tuberkulosis aktif dan laten dengan askariasis maupun tanpa askariasis tidak berbeda signifikan. Simpulan penelitian ini adalah askariasis intensitas ringan tidak menekan respons Th1 dan tidak meningkatkan kejadian tuberkulosis aktif di daerah endemis rendah askariasis. ASCARIASIS IN LOW ENDEMIC AREA DOES NOT ASSOCIATE WITH THE INCREASE INCIDENCE OF ACTIVE TUBERCULOSISPolarization toward Th2 response in ascaris investation suppresses Th1 responses which is important in defence against tuberculosis. Such suppression is hipothesized to supress the expression of IL-12Rẞ2 by IL-4. The purpose of this study was to find out the relationship between ascaris investation and TB in low endemic area of ascariasis that is endemic for TB. We gathered samples from 30 adult active pulmonary TB patients and 29 adult latent TB patients as control. The study was performed in Bandung during April to June 2014. Ascaris investation was established with Kato-Katz smear technique and the detection of plasma level of the soluble receptor of IL-12Rẞ2 was conducted with enzyme linked immunosorbent assay (ELISA). We showed that the proportion of ascaris investation significantly higher in latent TB patients (13 from 29 subjects) compared to in active Tb patients (5 from 30 subjects) with p value 0.019. All subjects positive for ascaris investation had low intensity of investation in accordance with low endemicity. Also, the median level of IL-12Rẞ2 did not differ between active and latent TB patients with ascaris or without ascaris investation. We concluded that low intensity of ascaris investation does not associate with suppression of Th1 response, as assessed by IL-12Rẞ2 receptor level, hence does not associate with the increase incidence of active tuberculosis.
