Abstract: Bisphenol A (BPA), commonly found in plastic packaging and cans, can induce oxidative stress. This study was aimed to prove that oral BPA could decrease superoxide dismutase (SOD) and increase F2-isoprostan levels in male Sprague Dawley rats. This was an experimental study using randomized pretest-posttest control group design. There were 14 rats (Rattus norvegicus), male, Sprague Dawley strain, 8-10 weeks old, as subjects. Rats were divided into two groups with 7 rats each. The control group (P0) was treated with placebo for 21 days and the treatment group (P1) was treated with oral BPA dose of 400mg/kg for 21 days. Before and after treatment for 21 days, blood was drained through the canthus medial sinus orbital and urine was collected as pretest and posttest data. SOD and F2-isoprostan levels were then examined by using ELISA. The results showed that before treatment (pretest), the mean SOD level in P0 group was 42.51±3.127 U/mL and in P1 group was 41.87±2.477 U/mL (P > 0.05). The mean F2-isoprostane level in P0 group was 3.18±0.599 ng/ml and in P1 group was 3.22±0.489 ng/ml (P > 0.05). However, after treatment for 21 days (posttest), the mean level of SOD in P0 group was 43.52±3.472 U/mL and in P1 group was 31.84±2.563 U/mL (P <0.01). The mean level of F2-isoprostane in P0 group was 2.94±0.500 ng/ml and in P1 group was 4.47±0.241 ng/ml (P < 0.01). The analysis of the treatment effect showed significant decreased level of SOD and increased level of F2-isoprostane in P1 group (P < 0.01). Conclusion: Oral bisphenol A could decrease superoxide dismutase (SOD) and increase F2-isoprostan levels in male Sprague dawley rats.Keywords: bisphenol A (BPA), SOD, F2-isoprostane, Sprague Dawley ratsAbstrak: Bisphenol A (BPA) banyak ditemukan dalam kemasan plastik dan kaleng dan dapat menyebabkan peningkatan radikal bebas.

Cause Of Deaths

<p>ABSTRACT</p><p>Background: Hypercholesterolemia is a main risk factor of cardiovascular disease that remains the higher cause of deaths in the world. Black soy bean containing protein, fiber, vitamin, isoflavon, and flavonoid can decrease serum cholesterol level. Yoghurt contains lactic acid bacteria that decrease total and LDL cholesterol, triglyceride, and increase the HDL cholesterol. Processing of black soy bean into black soyghurt can increase its isoflavon’s activity by forming aglicone, which has higher activity to decrease cholesterol.</p><p>Objectives: To know the effect of black soyghurt feeding to LDL, HDL, and HDL ratio of hypercholesterolemic rats.</p><p>Methods: This research was true-experimental using post test only with control group design. Subjects were 20 male Sprague dawley rats, 2 months old, inducted hypercholesterolemia, given black soyghurt diet using 2 mL, 3 mL, and 4 mL dosage for 21 days. Serum lipid profile were measured by CHOD-PAP<br />and GPO-PAP methods respectively. Normality of the data were tested by Shapiro Wilks test. Data were analyzed by paired t test and Anova continued by LSD test using computer program.</p><p>Results: The study revealed that black soyghurt 4 mL/day decreased LDL (p=0.02) at the most significant level. The other doses did not significantly influence the levels of LDL (p&gt;0.05 ). There was also no effect of black soyghurt feeding on serum HDL cholesterol levels (p=0.11) and the ratio of LDL /HDL (p=0.087).</p><p>Conclusions: The feeding of black soyghurt at the dosage of 4 mL/day to hypercholesterolemic rats could decrease the serum LDL, but could decrease the ratio of LDL / HDL significantly.</p><p>KEYWORDS: black soyghurt, LDL/HDL ratio, hypercholesterolemic</p><p>ABSTRAK</p><p>Latar belakang: Hiperkolesterolemia merupakan faktor risiko penyakit kardiovaskuler yang menjadi penyebab kematian utama di dunia. Kedelai hitam mengandung protein, vitamin, serat, isoflavon, dan flavonoid yang mampu menurunkan kadar kolesterol. Yoghurt mengandung bakteri asam laktat yang mampu menurunkan kadar kolesterol total, LDL, dan trigliserida serta meningkatkan HDL. Pengolahan kedelai hitam menjadi black soyghurt meningkatkan aktivitas isoflavon dalam kedelai hitam menjadi aglikon yang lebih tinggi aktivitasnya dalam menurunkan kolesterol.</p><p>Tujuan: Untuk mengetahui pengaruh pemberian yoghurt kedelai hitam terhadap kadar LDL, HDL, dan rasio LDL/HDL pada tikus hiperkolesterolemia.</p><p>Metode: Jenis penelitian ini adalah true-experimental dengan post test only with control group design. Subjek penelitian adalah 20 tikus Sprague dawley jantan berusia 2 bulan, diinduksi hiperkolesterolemia, diberi black soyghurt dosis 2 mL, 3 mL, dan 4 mL selama 21 hari.

Abstract: This study was aimed to prove that administration of black cincau (Mesona palustris BL) leaf extract increased superoxide dismutase (SOD) levels of overtraining-induced male Wistar rats (Rattus norvegicus). This was a true experimental study using the randomized pretest-posttest control group design. Subjects were 16 male rats (Rattus norvegicus), 6-month old, Wistar strain, weighing 180-200 g, SOD level <39.3 U/mL (normal SOD level), divided into two groups: the control group (P0) and the treatment group (P1). The P0 group was given excessive physical training and aquadest for 14 days, while the P1 group was given excessive physical training and black cincau leaf extract of 54 mg/200 g BW daily for 14 days. The results showed that the mean SOD level before treatment (pretest) in the P0 group was 30.63±2.26 U/mL while in the P1 group was 31.31±2.52 U/mL (P >0.05). After 14-day treatment (posttest), the mean SOD level in the P0 group was 29.36±2.83 U/mL while in the P1 group was 41.31±2.35 U/mL (P <0.01). Further analysis showed that there was no change of SOD levels in the P0 group (P > 0.05), but in the P1 group there was a significant increase of SOD levels from 31.31±2.52U/mL to 41.31±2.35U/mL (P <0.01). Conclusion: Administration of black cincau leaf extract of 54 mg per 200 g of body weight increased SOD level of overtraining-induced male Wistar rats (Rattus norvegicus).Keywords: black cincau leaves, SOD, excessive physical activityAbstrak: Penelitian ini bertujuan untuk membuktikan bahwa pemberian ekstrak daun cincau (Mesona palustris BL) dapat meningkatkan kadar superoksida dismutase (SOD) tikus Wistar (Rattus norvegicus) jantan yang diinduksi pelatihan fisik berlebih. Jenis penelitian ialah eksperimental murni menggunakan randomized pretest-posttest control group design. Subjek penelitian ialah 16 ekor tikus putih jantan (Rattus norvegicus) galur Wistar berumur 6 bulan, sehat, berat badan 180-200 gr, dan kadar SOD <39,3 U/mL (kadar SOD normal), yang dibagi menjadi dua kelompok, yaitu kelompok kontrol (P0) dan kelompok perlakuan (P1), masing-masing berjumlah 8 ekor tikus. Kelompok P0 diberikan pelatihan fisik berlebih dan akuades secara sonde selama 14 hari, dan kelompok P1 diberikan pelatihan fisik berlebih dan ekstrak daun cincau dosis 54 mg/200 gr BB tikus selama 14 hari. Hasil penelitian menunjukkan bahwa rerata kadar SOD sebelum perlakuan (pretest) pada kelompok P0 ialah 30,63±2,26 U/mL, sedangkan pada kelompok P1 ialah 31,31±2,52 U/mL (P >0,05). Setelah perlakuan selama 14 hari (posttest), rerata kadar SOD pada kelompok P0 ialah 29,36±2,83 U/mL, dan pada kelompok P1 ialah 41,31±2,35 U/mL (P <0,01). Hasil analisis efek perlakuan menunjukkan bahwa pada kelompok P0 tidak terjadi perubahan kadar SOD (P >0,05), namun pada kelompok P1 terjadi peningkatan bermakna kadar SOD dari 31,31±2,52 U/mL menjadi 41,31±2,35U/mL (P <0,01). Simpulan: Ekstrak daun cincau dosis 54 mg/200 gr BB tikus dapat meningkatkan kadar SOD tikus Wistar (Rattus norvegicus) jantan yang diinduksi pelatihan fisik berlebih.Kata kunci: daun cincau, SOD, aktivitas fisik berlebih
