"ABSTRAKFluoroquinolon memiliki efek terhadap mekanisme penyembuhan ruptur tendon Achilles. Penelitian ini dilakukan untuk menilai efek siprofloksasin terhadap proses penyembuhan tendon in vivo. Efek obat diperiksa terhadap biomekanik dan histopatologik tendon Achilles tikus. Uji eksperimental ini menggunakan siprofloksasin selama 2 kali/hari selama 15 dan 35 hari berturut-turut. Asesmen pada tendon Achilles mencakup pengukuran ultimate tensile force (UTF) dan skor histopatologik Bonar. Rerata UTF dan skor proliferasi tenosit pada grup kontrol signifikan dibandingkan grup perlakuan pada protokol 15 hari p<0.004 dan p<0,002. Tidak ada perbedaan bermakna pada skor kolagen, ground substance, dan vaskularisasi. Berdasarkan penelitian ini, siprofloksasin terbukti menurunkan kekuatan biomekanik, metabolisme tenosit, kolagen, dan matriks selama proses penyembuhan tendon Achilles model tikus.

ABSTRACTFluoroquinolon has a side effect on the healing process of Achilles tendon rupture. The purpose of this experimental research is to evaluate ciprofloxacin towards tendon healing (in vivo) in respect to biomechanic and histopathologic of Achilles tendon. Ciprofloxacin is administered 2 times per day within 15 and 35 days follow-up. After that, Achilles tendon is measured for ultimate tensile force (UTF) and Bonar histopathologic score. According to this research, the mean of UTF and tenocyte proliferation score is significant in control group compared to intervention group on day-15 (p<0.004 and p<0.002 consecutively). The statistical significance is narrow in collagen score, ground substance, and vascularization. Based on those foundings, ciprofloxacin has been proven to reduce biomechanical force, tenocyte metabolism, collagen, and matrix during the healing process of Achilles tendon in rat model."

"Nanopartikel merupakan senyawa dengan ukuran 1-100nm. Pembuatan nanopartikel dapat dilakukan dengan tiga cara, baik secara kimia, fisika, maupun biologi (green synthesis). Pembuatan nanopartikel secara Green synthesis yang dimediasi oleh tanaman menarik perhatian peneliti karena relatif aman, murah, mudah dilakukan, dan ramah lingkungan. Pembuatan nanopartikel CuCo2O4 sebagai katalis secara green synthesis melibatkan tumbuhan (Vitis Vinifera) pada bagian daunnya. Menggunakan tumbuhan sebagai media sintesis dilpilih karena kandungan fitokimia pada tumbuhan memiliki sifat pereduksi dan agen penstabil. Nanopartikel CuCo2O4 berhasil disintesis dan dapat digunakan sebagai katalis pada reaksi Doebner untuk menghasilkan suatu senyawa derivat quinoline-4-carboxylic acid. Reaksi Doebner melibatkan anilin, asam piruvat dan senyawa aldehid aromatik. Senyawa derivat quinoline-4-carboxylic acid hasil sintesis dikonfirmasi secara KLT, IR, UV-Vis, dan LCMS. Hasil karakterisasi menunnjukkan telah terbentuk senyawa quinoline-4-carboxylic acid yang sesuai. Penggunaan katalis CuCo2O4 menghasilkan produk sebesar 60,30% pada produk 1 ; 77,83% pada produk 2; 19,23% pada produk 3; dam 19,98% pada produk 4. Masing-masing produk dilakukan pengujian antikanker dan diperoleh data IC50<200µg/L yang menunjukkan tingkat sitotoksik yang sedang untuk semua produk hasil sintesis.

Nanoparticles are compounds with a size of 1-100nm. The manufacture of nanoparticles can be done in three ways, either chemically, physically, or biologically (green synthesis). The production of nanoparticles by means of plant-mediated green synthesis has attracted the attention of researchers because it is relatively safe, inexpensive, easy to perform, and environmentally friendly. Making CuCo2O4 nanoparticles as a catalyst by means of green synthesis involves plants (Vitis Vinifera L) in their leaves. Using plants as a synthesis medium was chosen because the phytochemicals in plants have reduced and stabilizing properties. CuCo2O4 nanoparticles have been successfully synthesized and can be used as a catalyst in the Doebner reaction to produce a quinoline-4-carboxylic acid derivative compound. The Doebner reaction involves aniline, pyruvic acid and aromatic aldehydes. The synthesized quinoline-4-carboxylic acid derivatives were confirmed by TLC, IR, UV-Vis, and LCMS. The characterization results showed that a suitable quinoline-4-carboxylic acid compound had been formed. The use of CuCo2O4 catalyst produces a product of 60.30% in product 1; 77.83% in product 2; 19.23% in product 3; and 19.98% in product 4. Anticancer testing was carried out for each product and IC50<200µg/L data was obtained which indicated a moderate cytotoxic level for all synthesized products."

"Kuinolon adalah antibiotik berspektrum luas, yang digunakan untuk mengobati infeksi oleh bakteri gram positif ataupun negatif. Pemilihan antibiotik yang tepat sangat menentukan keberhasilan pengobatan infeksi bakteri. Kepekaan bakteri senantiasa berubah pada waktu dan tempat yang berbeda, sehingga perlu adanya analisis rutin mengenai pola sensitifitas bakteri terhadap antibiotik. Pola sensitifitas ini sangat diperlukan sebagai dasar pemilihan antibiotik untuk terapi empirik pada kasus infeksi. Penelitian ini menggunakan data sekunder yang diperoleh dari hasil uji resistensi bakteri terhadap berbagai antibiotika di Laboratorium Mikrobiologi Klinik Fakultas Kedokteran Universitas Indonesia tahun 2001-2006, yang memperoleh bahan pemeriksaan klinik dari berbagai rumah sakit terutama RSCM dan juga dari praktik pribadi di Jakarta. Data penelitian ini menggunakan bakteri yang diisolasi dari darah yang diuji sensitivitasnya terhadap siprofloksasin, gatifloksasin, moksifloksasin, ofloksasin, dan levofloksasin. Data diolah dengan software WHONET 5.4. Metode statistik yang digunakan adalah metode cross-sectional deskriptif. Dari 791 isolat yang berasal dari 770 pasien dengan bakterimia positif, ditemukan bakteri gram negatif sebanyak 525 isolat dan bakteri gram positif 266 isolat. Bakteri gram negatif terbanyak adalah Acinetobacter anitratus, Salmonella Typhi, Pseudomonas aeruginosa, dan Klebsiella pneumoniae. Sedangkan bakteri gram positif terbanyak adalah Staphylococcus epidermidis dan Staphylococcus aureus. Sensitivitas bakteri-bakteri tersebut terhadap siprofloksasin, gatifloksasin, moksifloksasin, ofloksasin, dan levofloksasin, umumnya masih sangat baik. Fluorokuinolon dapat dijadikan pilihan dalam terapi empiris pada penyakit infeksi oleh bakteri hingga hasil kultur dan uji resistensi diperoleh.

Quinolones are wide spectrum anitmicrobial agents used to treat the infection by both of the gram-positive bacteria and gram-negative bacteria. The exact selection of antibiotic is critical for the success of medical treatment for the bacterial infections. The sensitivity of the bacteria always changes at the different time and place, results the need of routine analysis about the pattern of bacterial sensitivity against antibiotics. Understanding the pattern of bacterial sensitivity can help in choosing antibiotic as empirical therapy. The data that was taken is the secondary data received from results of the test of bacterial resistance against various antibiotics from the year 2001-2006 that was sent to the Laboratory of Clinical Microbiology, Faculty of Medicine of University of Indonesia. The data was processed with software WHONET 5,4. The statistical method used was crosssectional descriptive method. From 791 isolat that came from 770 patients with bacteremia, the gram-negative bacteria are 525 isolat and the gram-positive bacteria are 266 isolat. The most gram-negative bacteria isolated are Acinetobacter anitratus, Salmonella Typhi, Pseudomonas aeruginosa, and Klebsiella pneumoniae. Whereas the most gram-positive bacteria are Staphylococcus epidermidis and Staphylococcus aureus. The sensitivity of these bacteria against ciprofloxacin, gatifloxacin, moxifloxacin, ofloxacin, and levofloxacin, generally are still very well. Fluoroquinolone can be a choice in empirical therapy in the infection by the bacteria untill the results of culture and the test resistance have been received."
