Abstract

ABSTRAK Metode yang digunakan dalam skrining obat antihiperurisemia in vitro berdasarkan pada kemampuan suatu bahan menghambat enzim xantin oksidase dalam mengubah substrat xantin menjadi asam urat. Para peneliti mengukur aktivitas antihiperurisemia berdasarkan asam urat yang terbentuk atau xantin yang tersisa. Untuk mengetahui presisi kedua pengukuran tersebut, telah dilakukan pengujian aktivitas antihiperurisemia alopurinol berdasarkan pengukuran serapan pada panjang gelombang 291 nm dan 268 nm. Pada kondisi optimum diperoleh simpangan baku relatif persen penghambatan berdasarkan jumlah asam urat yang terbentuk 0,24-1,30%, sedangkan berdasarkan sisa xantin adalah 0,25-2,39%. Kata kunci : pengambatan, xantin oksidase, in vitro, alopurinol, presisi  ABSTRACT The method used in in vitro antihiperurisemia drug screening based on the ability of a substance  to inhibit the xanthine oxidase enzyme in converting the substrate xanthine to uric acid. The researchers measured the hyperuricemia treatment activity based on the formation of uric acid or the remaining xanthine. To determine the precision of the measurements, antihiperurisemia activity of allopurinol was conducted by measuring absorption at a wavelength of 291 nm and 268 nm. At the optimum conditions, the  relative standard deviation of percent inhibition based on the amount of uric acid was 0.24 to 1.30%, while based on the rest of the xanthine was 0.257 to 2.39%. Keywords : inhibition, xanthine oxidase, in vitro, allopurinol, precision

Abstract

To prevent hyperglycemia, people need alternative source of carbohydrate with low glycemic index. Porang bulbs from Amorphophallus muelleri Blume plant is rich on glucomannan, that could prevent elevation of blood glucose level. The aim ofthis study is to determine aglycemic index and intestinal transit index of porang bulbs flour. Glycemic index determined by glucose tolerance test method and intestinal transit index determined by measuring the intestinal transit distance of mice administered 1,5 kg BW intragastically the porang suspense. Forty-five minute later mice was given carbo absorben as a marker. At 15 minute later mice was sacrificed by cervical dislocation and the distance of charcoal marker was measure from pillory. The results shows that porang has glycemic index 85 compare with glucose 100 and treatment with porang flour caused the intestinal motility was faster (intestinal transit index -0,42) rather than wheat four (0,32). Its mean that, porang flour shorten the retention time of chymus in intestinum s0 it will inhibit the absorbtion of'glucose.

Abstract

ABSTRACT : The Binahong plant (Anredera cordifolia (Ten.) Steenis) has been used to treat several types of diseases. To find another possible biological activities, we investigated binahong leaves antihyperuricemic and antioxidant activity through in vitro assay of xanthine oxidase inhibiting activity of binahong ethanol extract and through in vivo assay by measuring uric acid and malondialdehyde (MDA) levels in plasma of hyperuricemic rat treated with binahong ethanol extract. Rat was induced into hyperuricemiccondition using chicken concentrate which is administered orally for 7 days and potassium oxonic through intraperitoneal routeon the last day. In treatment groups, rat were administered with extract at doses 200, 400 and 800 mg/kg BW respectively along the induction periods, while theother group were given allopurinol. On 7thday, the levels of plasma uric acid andMDA were measured by enzymatic methods and tiobarbituric acid reactive substances (TBARS) methodconsecutively. In vitro study shows that at 100 ppm,binahong leavesethanolic extract inhibit xanthine oxidase activity by24.33%, while in vivo study showedthe extract hadantihyperuricemic activity by decreasinguric acid levels at dose 800 mg / kgBB about 60,88% compared to hyperuricemia control group. Plasma MDA levels showed that hyperuricemia induction for 7 days was not enough to show significant increase of MDA levels.As conclusion, the ethanolic extract of binahong leaves could lower uric acid levels but in this study  it’s activity as antioxidant could not be proven through MDA measurements.

Abstract

Top Brand Index data during 2012-2018 shows a stagnant and prone to declining growth percentage for certain immunomodulatory products. Toovercome this problem, producers tried to promote their products vigorously and to apply the right marketing strategy of the electronic word of mouth (e-WOM). Moreover, strengthening brand image on purchasing decision could be an alternative way to increase the market share of immunomodulatory producer companies. Hence, this study aimed (1) to determine the effect of e-WOM toward the decision to purchase immunomodulator products (research conducted in the DKI Jakarta area) as well as (2) the brand image to the same matter, then (3) to investigate further to what extent e-WOM as a marketing strategy influence the brand image of the marketed product. This study used a survey method and questionnaires has been distributed to 384 respondents in DKI Jakarta area. The obtained data were then analysed using Structural Equation Modeling (SEM)-PLS (Partial Least Square) by means of SmartPLS software. The results showed that (1) e-WOM affects significantly toward the decision to purchase immunomodulatory products and so does (2) the brand image. Then, (3) e-WOM proved to have a significant effect on the brand image of immunomodulatory products.

Abstract

LATAR BELAKANGStandar Nasional Akreditasi Rumah Sakit (SNARS) edisi 1/2018 menjadikan kejadian Infeksi Daerah Operasi (IDO) sebagai salah satu indikator mutu untuk menilai kinerja pengendalian infeksi di rumah sakit. Pemberian antibiotik lanjutan pascaoperasi sectio caesaria (SC) menjadi isu yang penting untuk dikaji, mengingat operasi ini pada dasarnya tidak membutuhkan pemberian antibiotik lanjut pascaoperasinya. Penelitian ini bertujuan untuk melihat apakah pemberian antibiotik lanjutan pascaoperasi SC berpengaruh terhadap penurunan IDO superfisial dan Length of Stay (LOS) pasien. METODEPasien dibagi menjadi 2 kelompok dengan jumlah masing-masing sebesar 49 subjek. Kelompok pertama adalah kelompok subjek yang diberikan antibiotik lanjut pascaoperasi SC dan kelompok kedua adalah kelompok subjek yang tidak diberikan antibiotik lanjutan pascaoperasi SC, kemudian dari masing-masing kelompok dikaji kemungkinan munculnya tanda IDO superfisial dan LOS pasien. Desain penelitian ini adalah kohort retrospektif dengan data sekunder dari rekam medis pasien Januari 2019-Desember 2019. Uji analisa dengan Chi-square. HASILSetelah mengontrol variabel perancu, pemberian antibiotik lanjut pascaoperasi SC tidak signifikan berpengaruh menurunkan kemungkinan munculnya tanda IDO superfisial (OR=0.157;p=0.098; 0.02-1.41 IK 95%), juga tidak memiliki pengaruh terhadap LOS pasien (OR=1.73; p=0.562; 0.27-10.85 IK 95%). KESIMPULANTidak terdapat pengaruh dari pemberian antibiotik lanjutan terhadap tanda kejadian IDO superfisial dan LOS pada pasien post SC. Pemberian antibiotik lanjutan pascaoperasi SC merupakan pemberian antibiotik yang tidak bijak.

Abstract

Penelitian ini bertujuan untuk mengetahui pengaruh edukasi dan monitoring pengobatan tuberkulosis pada PKM dengan intervensi Apoteker (PKM Saumlaki) dan PKM tanpa intervensi Apoteker (PKM Larat). Responden penelitian ini adalah pasien baru TB dan Pengawas Menelan Obat (PMO) di kedua PKM pada bulan September-November 2020. Penelitian ini merupakan jenis penelitian quasi experimental dengan rancangan two group pretest-posttest design. Peran apoteker berupa edukasi dan monitoring dilakukan pada responden PKM Saumlaki selama 8 minggu observasi. Data dikumpulkan dalam bentuk kuesioner dan data catatan pengobatan di PKM masing-masing. Hasil penelitian menunjukkan karakteristik demografi responden di kedua PKM tidak berbeda bermakna. Perbedaan bermakna antara kedua PKM terdapat pada data pengetahuan, kepatuhan, outcome klinis berdasarkan BTA negative pada akhir pengobatan tahap intensif, dan data kepuasan pasien terhadap PMO. Sedangkan efek samping dan berat badan pasien antara kedua PKM tidak berbeda bermakna. Hal ini menandakan ada pengaruh edukasi dan monitoring oleh apoteker terhadap peningkatan jumlah pasien yang berhasil menjalani pengobatan TB. Analisis mengenai faktor yang signifikan berhubungan dengan keberhasilan pengobatan memberikan hasil bahwa faktor yang signifikan berpengaruh adalah adanya intervensi apoteker pada tingkat kepatuhan pasien, tingkat pengetahuan pasien dan PMO. Kesimpulan yaitu edukasi dan monitoring pengobatan langsung oleh apoteker pada pasien TB di PKM Saumlaki di KKT berpengaruh meningkatkan keberhasilan pengobatan pasien tuberkulosis
