Abstract

Kerusakan hepar sering disebabkan karena stress oksidatif yang berkaitan erat dengan radikal bebas. Karbon tetraklorida merupakan senyawa toksik sumber radikal bebas penyebab timbulnya stress oksidatif. Adanya kerusakan jaringan tersebut dapat ditandai dengan meningkatnya kadar malonildialdehid (MDA) dan kenaikan kadar enzim superoksid dismutase (SOD). Ganggang hijau (Ulva lactuca L.) mengandung senyawa melatonin yang berfungsi sebagai antioksidan. Penelitian ini bertujuan untuk mengetahui aktivitas ekstrak etanol ganggang hijau (Ulva lactuca L.) sebagai antioksidan dengan parameter kadar MDA dan aktivitas enzim SOD hepar tikus yang diinduksi CCl4. Penelitian ini bersifat eksperimental menggunakan post-test only control group design dilakukan pada 25 hewan uji yang dibagi menjadi lima kelompok, terdiri dari kelompok I (normal) hanya diberi makan dan minum, kelompok II diberi CMC-Na 1%, kelompok III (kontrol pembanding) diberi tablet curcuma 200 mg/KgBB, kelompok IV dan V diberi ekstrak etanol ganggang hijau dosis 100 dan 200 mg/KgBB. Perlakuan dilakukan selama 21 hari dan pada hari ke-22 diinduksi CCl4 1,0 ml/KgBB intraperitoneal(i.p) kecuali kelompok I. Setelah 24 jam, hepar tikus diambil dan diukur kadar MDA hepar dengan metode TBARs. Aktivitas enzim superoksida dismutase (SOD) menggunakan metode spektrofotometri. Analisis data menggunakan One way ANOVA dengan taraf kepercayaan 95% dan dilanjutkan dengan uji LSD. Hasil penelitian menunjukkan bahwa kadar MDA hepar meningkat dan aktivitas enzim SOD menurun secara signifikan akibat induksi CCl4 (p<0,05). Tablet curcuma dosis 200 mg/kgBB, ekstrak etanol ganggang hijau dosis 100 dan 200 mg/KgBB dapat menurunkan kadar MDA dan meningkatkan aktivitas SOD hepar tikus yang diinduksi CCl4 secara signifikan (p<0,05). Kesimpulan penelitian ini adalah ekstrak etanol ganggang hijau (Ulva lactuca L.) mempunyai aktivitas antioksidan dengan menurunkan kadar MDA dan meningkatkan aktivitas enzim SOD hepar tikus yang diinduksi CCl4.

Abstract

Hepar merupakan organ yang berperan dalam pengaturan homeostasis tubuh meliputi metabolisme, biotransformasi, sintesis dan imunologi. Penyebab penyakit hepar bervariasi, diantaranya adalah virus, obat-obatan, alkohol dan stress oksidatif yang merupakan faktor utama. Jumlah radikal bebas yang melebihi antioksidan menyebabkan terjadinya stres oksidatif. Sidaguri (Sida rhombifolia L.) mengandung senyawa fenol dan flavonoid yang berkhasiat sebagai antioksidan. Penelitian ini bertujuan untuk menguji efek hepatoprotektif ekstrak etanol daun sidaguri (EEDS) terhadap nilai SGPT-SGOT, gambaran histopatologi hepar tikus dan rasio berat hepar yang diinduksi carbon tetrachloride (CCl4). Dua puluh lima tikus dibagi menjadi 5 kelompok. Kelompok I merupakan kelompok normal yang hanya diberi makan dan minum, kelompok II merupakan kelompok kontrol yang diinjeksi CCl4 secara intraperitoneal dengan dosis 1 mL/KgBBdan kelompok (III, IV dan V merupakan kelompok perlakuan yang diberi EEDS peroral dengan dosis: 25, 50 dan 100 mg/KgBB) berturut-turut selama 21 hari. Pada hari ke 21 kelompok ini diinjeksi CCl4 1 mL/KgBB secara intraperitoneal 1 jam setelah perlakuan. Data rasio berat organ hepar dari masing masing kelompok dianalisis secara statistik menggunakan analisis varian (ANOVA), LSD post hoc test P<0,05 untuk menentukan perbedaan signifikan. Hasil penelitian menunjukkan bahwa rasio berat hepar pada kelompok II (kontrol) 216,52±15,04 berbeda signifikan dibandingkan dengan kelompok III, IV dan V berturut turut dengan nilai 436,56± 46,78; 438,86±44,79; dan 534,46±45,49. Hal ini menunjukkan bahwa pemberian EEDS dapat menaikkan rasio berat hepar. Data ini didukung dengan nilai SGPT dan SGOT yang berbeda bermakna dengan kelompok kontrol (p<0,05). Dilihat dari gambaran histopatologi hepar, pada  kelompok  II (kontrol), III, IV dan V berturut-turut tidak  menunjukkan adanya nekrosis karena CCl4. Kesimpulan dari penelitian ini bahwa EEDS dapat melindungi hepar berdasarkan rasio berat hepar dan nilai SGPT-SGOT, namun belum dapat disimpulkan bahwa EEDS memiliki efek hepatoprotektif dilihat dari gambaran histopatologi.

Abstract

Red ginger extract is one of the new medicinal discoveries made from natural substances that has pharmacological benefits in the treatment of diabetes. Many gingerol components in red ginger can aid in the treatment of diabetes mellitus. However, the administration of red ginger extract is not so effective, a delivery system such as SNEDDS (Self-Nano Emulsifying Drug Delivery System) must be developed. When compared to standard formulations, SNEDDS can boost the oral bioavailability of lipophilic medicines by up to 2.4 times. The oil phase of SNEDDS red ginger extract was virgin coconut oil, with tween 80 as a surfactant and PEG 400 as a co-surfactant. The fourth formula of the SNEDSS preparation of red ginger rhizome extract satisfied the requirements for a good nanoemulsion particle size in this study, with a percent T value of 99.7% and PSA test data showing that this formulation met the requirements for a good nanoemulsion particle size

Abstract

Colorectal cancer prevention is closely linked to gut microbiota modulation, particularly by increasing lactic acid bacteria (LAB) and short-chain fatty acids (SCFA). This study investigates the effect of fermented red rice bran on colon microbiota improvement. Fermented bran was produced by mixing red rice bran with water and yeast, followed by an analysis of the proximate composition, dietary fiber, resistant starch, antioxidants, and phenols. A quasi-experimental study was conducted on 30 mice, assigned to normal, negative control, 10% bran, 20% bran, 10% fermented bran, and 20% fermented bran groups. Colorectal cancer was induced using DMBA (20 mg/kgBW) intraperitoneally four times over two weeks. Treatment groups received bran or fermented bran ad libitum for 14 days. Cecal analysis showed that 20% red rice bran and 10% fermented bran significantly increased SCFA levels (p < 0.05), suggesting improved microbiota function, but did not significantly alter pH or LAB counts. These findings highlight the potential of fermented red rice bran in modulating gut microbiota, though further studies are needed to elucidate its long-term effects and mechanisms in colorectal cancer prevention.

Abstract

Sambiloto (Andrographis paniculata) has been known empirically as a plant that has benefits as a traditional antidiabetic Javanese medicine to treat diabetes mellitus (DM). The main compound contained in sambiloto is andrographolide which has a hypoglycemia effect. Andrographolide has low solubility in water and poor bioavailability due to biotransformation by P-glycoprotein in the intestinal tract which causes andrographolide to metabolize more quickly in the duodenum and jejunum. To overcome this extract ethanol of sambiloto (EES) formulated to patch transdermal. Enhancers can affect the characteristics of transdermal patch preparations which affect the pharmacological activity of transdermal patch preparations. The critical point of transdermal patch preparation is the selection of enhancers which is one of the compounds to increase the penetration of active substances in the skin by disrupting the permeability of the stratum corneum. The aim of this research is to determine the effect of variations in the combination of oleic acid and tween 80 as an enhancer on the physical characteristics of EES patches.The methods of extraction sambiloto use soxhetation with ethanol 96% as solvent. The formulation of EES patch transdermal using solvent casting technique with various concentration enhancer tween-80 and oleic acid. This research was conducted by making 3 formulas, where F1  (1:1), F2 (1:3) and F3 (1:3). The evaluations include weight uniformity, thickness, water content, pH and folding endurance of the patch. The result of visual appearance the patch EES has a dark green with aroma specific of EES. The characteristics of EES transdermal patches were affected by the ratio of tween-80 and oleic acid as the enhancers. The combination of oleic acid and tween 80 as a permeation enhancer has an influence on physical characteristics (weight and thickness) of EES patches.
