"Pendahuluan: Pengobatan Kolitis Ulseratif (KU) hingga saat ini masih dilakukan dengan cara pemberian obat-obatan antiinflamasi, seperti 5-aminosalicylic acid (5-ASA), hingga pembedahan. Selain pengobatan konvensional, dikembangkan pula pengobatan alternatif yang memanfaatkan bahan-bahan dari alam seperti elagitanin. Elagitanin danderivatnya, yakni asam elagat, dapat ditemukan dalam jumlah yang banyak pada kulit buah delima dan diduga memiliki efek antiinflamasi yang bermanfaat untuk terapi alternatif kolitis. Oleh karena itu, penelitian ini hendak menelusuri lebih lanjut pengaruh ekstrak etanol kulit buah delima terhadap ekspresi NF-kB sebagai penanda inflamasi. Metode: Desain penelitian yang digunakan dalam penelitian ini adalah eksperimental. Penelitian ini menggunakan organ kolon mencit yang telah diberikan perlakuan di penelitian dan dikelompokkan ke dalam 6 kelompok sebagai berikut: kelompok tanpa perlakuan (KTP), kontrol negatif (KN) yang diberikan DSS2%, kontrol positif 1 (KP1) yang diberikan DSS2% dan aspirin 43 mg/kgBB/hari, kontrol positif 2 (KP2) yang diberikan DSS2% dan asam elagat 26 mg/kgBB/hari, serta kelompok dosis 1 (KD1) dan 2 (KD2) yang diberikan DSS2% dan ekstrak kulit delima dalam dosis 240 mg/kgBB/hari dan 480 mg/kgBB/hari.

Introduction: Up until now, Ulcerative Colitis (UC) treatment is mainly done conservatively by using antiinflammatory drugs, such as 5-aminosalicylic acid (5-ASA), or surgery. In addition to convensional treatment, alternative treatment that uses natural ingredient, such as elagitanin, is now under development. Elagitanin and its derivative, ellagic acid, can be found abundantly in pomegranate peel, and are expected to own an antiinflammatory property that can be considered to be an alternative choice for UC treatment. Therefore, this study is conducted with the intention of acknowledging the effect of pomegranate peel ethanol extract on NF-κB expression in mice’s colon tissue induced with DSS. Method: Study design used in this study is experimental. This study used the colonic tissue that was already prepared by the previous researcher and is divided into 6 groups: group without intervention (KTP), negative control (KN) with the administration of DSS 2%, positive control 1 (KP1) with the administration of DSS 2% and aspirin 43 mg/kgBW/day, positive control 2 (KP2) in which the mice are given DSS 2% and ellagic acid 26 mg/kgBW/day, and finally dose 1 and dose 2 group (KD1 and KD2) with the administration of DSS 2% and pomegranate peel extract with dose of 240 mg/kgBW/day and 480 mg/kgBW/day. Result and Discussion: Mean H Score for KTP is 129,0946; for KN is 200.3989; for KP1 is 165,5808; for KP2 is 159,0553; for KD1 is 186,1655; and for KD2 is 141,0696. Analysis using One Way ANOVA test shows a signicant result. Posthoc Tukey test shows a significant difference between KD2 and KN. Conclusion: pomegranate peel ethanol extract with dose of 480 mg/kgBW/day can decrease the NF-κB expression in mice’s colon epithelium induced with DSS."

Background: Azoxymethane AOM and dextran sodium sulfate DSS are chemical compounds frequently used to induce colorectal cancer in mice. Previous studies have shown that azoxymethane and DSS also cause nephrotoxicity. Omega 3 found on fish oil is known to have protective effect on kidney. However, omega 3 rich fish oil is still very underutilized in Indonesia.Aim To study the histopathologic features of kidney on mice induced AOM DSS after the administration of omega 3 rich fish oil.

Method: The experimental mice that had been induced using AOM 10 mg kg and DSS 2 for 2 weeks were allocated randomly into 4 groups as follows Control Group mice recieved no fish oil, Low Dose Group mice recieved 1.5 mg day fish oil, Medium Dose Group mice recieved 3 mg day fish oil, High Dose Group mice recieved 6 mg day fish oil. The omega 3 rich fish oil were given for 12 weeks. Pathology examination was done to grade tubular degeneration and vascular congestion.

Result: The histopathologic features found in the kidney were inflammation, tubular degeneration, necrosis, and vascular congestion. The percentage of severe 3 tubular degeneration on groups given low, medium, and high dose omega 3 rich olive oil were lower by 17.5 , 25 , and 37,5 respectively compared to control group. The administration of omega 3 rich fish oil showed less percentage of moderate 2 vascular congestion degree compared to control group however, increasing dose of omega 3 rich fish oil did not show different percentages of moderate vascular congestion among groups.

Conclusion: The result indicates the effect of omega 3 rich fish oil on preventing nephrotoxicity in mice induced by azoxymethane and DSS."

"Inflamasi lambung (gastritis) merupakan salah satu penyakit dengan prevalensi yang cukup tinggi di Indonesia. Inflamasi tersebut dapat terjadi akibat proses infeksi atau noninfeksi. Jika tidak ditangani dengan baik, dapat terjadi komplikasi ulkus, perforasi, dan perdarahan lambung. Terapi farmakologi untuk gastritis belum cukup efektif karena terdapat risiko efek samping dan interaksi obat. Hal tersebut mendorong berbagai penelitian untuk menelusuri potensi zat lain sebagai antiinflamasi. Ekstrak kulit delima diketahui mengandung asam elagat dan elagitanin yang telah terbukti mampu menghambat inflamasi di sejumlah organ. Belum terdapat studi mengenai efek ekstrak kulit delima terhadap inflamasi di lambung, khususnya delima yang tumbuh di Indonesia.Penelitian dilakukan dengan menggunakan 25 mencit yang terbagi menjadi lima kelompok. Mencit pada kelompok Kontrol Negatif, Dosis-1 (diberikan ekstrak 240 mg/KgBB), Dosis-2 (diberikan ekstrak 480 mg/KgBB), dan Kontrol Positif (diberikan asam elagat 26 mg/KgBB) diinduksi dengan DSS 2% sebanyak tiga siklus. Gambaran histopatologi (pewarnaan hematoxylin-eosin) mukosa lambung diamati pada sepuluh lapang pandang tiap preparat.Uji statistik menyatakan terdapat pengaruh signifikan ekstrak kulit delima terhadap infiltrasi sel radang (p= 0,001) dengan dosis 480 mg/KgBB, hiperplasia (p= 0,002) dengan dosis 240 mg/KgBB dan 480 mg/KgBB, serta displasia (p= 0,002) dengan dosis 480 mg/KgBB. Namun, tidak terdapat pengaruh signifikan ekstrak kulit delima terhadap angiogenesis (p= 0,114). Efek ekstrak kulit delima terjadi karena kandungan asam elagat dan elagitanin yang menghambat jalur inflamasi NF-κB sehingga terjadi penurunan ekspresi sitokin dan mediator inflamasi.Penelitian lebih lanjut untuk mengetahui dosis optimal, toksisitas, dan uji klinis dibutuhkan untuk memastikan efikasi serta keamanan suplementasi ekstrak kulit delima.

Gastric inflammation (gastritis) is one of the most prevalent disease in Indonesia. The etiologies are infection and noninfection factors. If not treated adequately, there can be complications, such as gastric ulcer, perforation, and bleeding. However, pharmacological treatments for gastritis have some risks of side effects and drug interactions. Many studies are conducted to discover potential of another substances as anti-inflammatory agents which have less side effects and drug interactions. Pomegranate peel extract contains ellagic acid and ellagitannin which have been proven to inhibit inflammation in some organs. Nevertheless, there has been no study proving its efficacy in inhibiting gastric inflammation.

This research used 25 mice which are divided into five groups. Mice in four groups consists of Negative Control, Dosage-1 (given the extract at a dose 240 mg/KgBW), Dosage-2 (given the extract at a dose of 480 mg/KgBW), and Positive Control (given ellagic acid at a dose of 26 mg/KgBW) were induced by DSS 2% in three cycles. Histopathological preparations were observed in ten microscopic fields (each slides) to examine the dependent variables.

There are significant differences in the amount of leukocyte infiltration (p= 0,001) at a dose of 240 mg/KgBW, hyperplasia (p= 0,002) at doses of 240 mg/KgBW and 480 mg/KgBW, and dysplasia (p = 0,002) at a dose of 240 mg/KgBW. However, there is no significant effect of pomegranate peel extract to the amount of angiogenesis (p= 0,114). It has anti-inflammatory effect because of the ellagic acid and ellagitannin contents inhibit the NF-κB inflammatory pathway which down regulate the inflammatory cytokines and mediators expressions.

Further researches to discover the optimal dose, toxicity, and clinical trials are necessary to ensure the efficacy and safety of pomegranate peel extract supplementation."
