Abstract

Diet asam lemak tak jenuh ganda (PUFA) telah diteliti dan terbukti dapat memodulasi peradangan, namun, hanya sedikit beberapa penelitian yang fokusnya pada patobiologi PUFA dengan menggunakan diet isokalori dan isolipid namun belum dapat dijelaskan apakah patologi terkait tersebut disebabkan oleh komposisi diet PUFA, metabolisme lipid, atau obesitas, karena sebagian besar penelitian membandingkan diet dengan yang diberi makan ad libitum. Stres oksidatif dan mitokondria hati berperan dalam patogenesis penyakit hati berlemak nonalcohol. Omega-3 PUFA memiliki peran protektif yang potensial terhadap kerusakan sel oksidatif yang diinduksi ROS pada tikus organ, terutama di hati. Atenuasi hepatic fibrosis oleh EPA (asam eicosapentaenoic) secara signifikan berhubungan dengan kadar ROS hati. EPA juga menekan peningkatan kadar ROS hati dan penurunan penanda oksidatif serum, seperti 8-isoprostan dan feritin. Ikan patin memiliki kandungan asam lemak tak jenuh ganda omega 3 serta selenium yang merupakan antioksidan sehingga dapat menghambat terjadinya progresifisitas kejadian NAFLD maupun MAFLD. Mekanismenya antara lain melalui jalur penghambatan stress oksidatif yang merupakan patofisiologi terjadinya NAFLD maupun MAFLD.

Abstract

Masyarakat modern saat ini mengalami perubahan gaya hidup yang mengakibatkan perubahan pada pola konsumsi makanan menjadi pola makanan yang tinggi lemak jenuh, tinggi gula dan rendah serat. Hal tersebut sering berakibat tingginya asupan makanan yang berkolesterol tunggi kemudian ditambah dengan seringnya frekuensi makan serta konsumsi sayur dan buah yang rendah, akan berpotensi menyebabkan kegemukan. stroke, aterosklerosis dan penyakit jantung koroner (PJK) memiliki faktor risiko paling besar menjadi penyakit serius di masyarakat yaitu hiperlipidemia sehingga diduga menjadi penyebab kesakitan dan kematian di negara adidaya dan berkembang. Membuktikan pengaruh ekstrak biji mahoni terhadap kadar MDA plasma tikus putih jantan galur wistar yang diberikan diet tinggi lemak. 32 ekor tikus dikelompokkan dalam kelompok kontrol negatif yang diberikan diet standart, kontrol positif yang diberikan diet tinggi lemak dan perlakuan yang mendapatkan diet tinggi lemak bersama ekstrak biji mahoni dengan dosis 100 mg/ kgBB dan 200 mg/kgBB. Diet tinggi lemak dikonsumsi tikus selama 14 hari dan pada hari ke 15 pada kelompok perlakuan ditambahkan ekstrak biji mahoni dengan dosis 100 mg/ kgBB dan 200 mg/kgBB Derajat stres oksidatif diukur dengan menggunakan indikator malondialdehyde (MDA). Kelompok kontrol negatif menunjukkan kadar MDA 78,5±16,92 µg/ml. Kelompok kontrol positif menunjukkan kadar MDA 97,17±26,559 µg/ml. Kelompok perlakuan yang mendapatkan diet tinggi lemak dan ekstrak biji mahoni dengan dosis 100 mg/kgBB, kadar MDAnya 65,25±24,126 µg/ml dan yang mendapatkan diet tinggi lemak dan ekstrak biji mahoni dosis 200 mg/kgBB 82±22,836 µg/ml. Uji ANOVA tidak mendapatkan hasil dengan perbedaan yang bermakna (p=0,151).

Abstract

Background: Intermittent fasting is done with one day of fasting and one day of eating as usual so that it can reduce oxidative stress, inhibit apoptosis and tissue damage which will reduce degenerative diseases. Fasting can activate SIRT1 and SIRT3 to prevent apoptosis by decreasing reactive oxygen species and inhibiting the mitochondrial permeability transition pore component. The accumulation of free radicals is one of the mechanisms that play a role in liver damage so that the SGOT enzyme present in the liver cells will leave and enter the blood circulation, so that the number of these enzymes in the blood increases. Objective : To prove that there was a decrease in the levels of SGOT (Serum Glutamic Oxaloacetic Transaminase) in male white rats (Ratus norvegicus) of the wistar strain which were fasted intermittently by the Daud fasting method after being induced by Paracetamol. Method : The research design used is a laboratory experimental research type where the method used is randomized the post only control group design. The experimental animals used were white rats (Rattus norvegicus) wistar strain 2-3 months old with an initial body weight of 150-200gr as many as 32 tails. During the fasting treatment, the research subjects were not given diet and drinking, while the non-fasting subjects were given a standard diet and drank regularly were divided into four groups, namely negative control with a water probe that was filtered for 10 days and 1ml of 1% CMC-Na, positive control with a probe. filtered water for 10 days and induction of paracetamol 400mg/kgBW, treatment 1 with standard diet and induction of paracetamol and treatment 2 with intermittent fasting and induction of paracetamol. Results: The results of this study indicate that One-Way ANOVA test obtained p value = 0.384. (p > 0.05) then H0 was accepted, there was no significant difference between the SGOT levels of the experimental animal group that was given a standard diet, the experimental animal group that was given intermittent fasting, the experimental animal group that was given a standard diet and paracetamol and the experimental animal group that was given intermittent fasting and paracetamol treatment. Conclusion: There is no effect of intermittent fasting with the Dawood fasting method on decreasing SGOT levels in male white rats (Rattus norvegicus) Wistar strain induced by paracetamol. Keywords: intermittent fasting, SGOT, paracetamol

Abstract

Cholesterol is divided into two different forms, including HDL (high-density lipoprotein, also referred to as "good fat". LDL (low-density lipoprotein), sometimes known as "bad fat". A buildup of cholesterol levels in the blood that can lead to cardiovascular disease. Sea cucumbers contain flavonoids which are a class of phenolic compounds. Flavonoids have properties as antioxidants. This study was conducted to determine the effect of ethanol extract of sea cucumber (Phyllophorus sp.) on HDL and LDL levels in wistar strain white rats induced by high fat diet. This study was conducted in the biochemistry laboratory of the Faculty of Medicine, Hang Tuah University using 30 white rats (Rattus norvegicus) male wistar strain. The rats were divided into 5 groups, namely, groups of animals that did not receive treatment, groups of animals fed a high-fat diet, groups of animals fed a high-fat diet and sea cucumber ethanol extract 8.5mg/kgBB, groups of animals fed a high-fat diet and sea cucumber ethanol extract at a dose of 17mg/kgBB, groups of animals fed a high-fat diet and simvastatin. On the 35th day, HDL and LDL levels were examined in all groups. The conclusion of the results of this study is that the administration of sea cucumber ethanol extract can increase HDL levels even though it is not significant, and can significantly reduce LDL levels. Keywords: Sea cucumber ethanol extract (Phyllophorus sp.), HDL, LDL, Wistar white rat, high fat diet
