YANG DIINDUKSI ASETOSAL ABSTRAK Latar Belakang: Penggunaan obat-obat antiinflamasi non steroid (NSAID) dalam jangka waktu lama dapat memicu timbulnya luka dan perdarahan pada mukosa lambung dan menyebabkan tukak. Mahkota dewa (Phaleria macrocarpa) adalah tanaman dengan sejarah etnofarmakologi yang panjang dan mengandung metabolit sekunder diantaranya flavonoid yang dapat meningkatkan produksi prostaglandin serta mengurangi sekresi asam, tanin yang mampu membentuk lapisan pelindung mukosa lambung. Tujuan: Tujuan dari penelitian ini adalah mengetahui efek gastroprotektif dan dosis efektif ekstrak etanol buah mahkota dewa (EEBMD) terhadap mukosa lambung tikus putih yang diinduksi dengan asetosal. Metode: EEBMD diekstraksi dengan metode maserasi. 35 ekor tikus jantan dibagi dalam 7 kelompok: kelompok normal; kelompok induksi; kelompok kontrol CMC-Na; kelompok kontrol positif; kelompok EEBMD 100; 200; dan 400 mg/kg bb. Seluruh kelompok diberikan perlakuan selama 7 hari kecuali kelompok induksi. Pada hari ke-6, tikus dipuasakan selama 36 jam, kemudian dinduksi dengan asetosal. 10 jam kemudian, hewan dikorbankan, diambil lambung untuk pemeriksaan parameter. Hasil: Hasil skrining fitokimia menunjukkan EEBMD mengandung metabolit sekunder yaitu flavonoid, tanin, saponin, alkaloid, glikosida. EEBMD dosis 100, 200, dan 400 mg/kg bb terbukti dapat menurunkan jumlah dan skor tukak, memperbaiki sel epitel, menaikkan pH dan total asiditas lambung. EEBMD dosis 100, 200 dan 400 mg/kg bb memiliki efek gastroprotektif dengan persen inhibisi tukak masing-masing 39%, 40,61%, dan 50,59% yang tidak berbeda secara signifikan dengan sukralfat, 44,98%. Kesimpulan: Hasil penelitian dapat disimpulkan bahwa EEBMD dosis 100, 200 dan 400 mg’kg bb memiliki efek gastroprotektif pada tikus yang tukaknya diinduksi menggunakan asetosal dengan persen inhibisi yang sama dengan sukralfat. Kata Kunci: Phaleria macrocarpa, gastroprotektif, induksi NSAID. vii Universitas Sumatera Utara GASTROPROTECTIVE EFFECT OF ETHANOLIC EXTRACT OF MAHKOTA DEWA FRUIT (Phaleria macrocarpa) IN ALBINO RATS GASTRIC MUCOSA (Rattus norvegicus L.) INDUCED BY ACETOSAL ABSTRACT Background: Prolonged use of non-steroidal anti-inflammatory drugs (NSAIDs) can cause sores and bleeding in gastric mucosa and cause ulcers. Mahkota dewa (Phaleria macrocarpa) is a plant with long ethnopharmacological usage history and contains secondary metabolites including flavonoids that can increase prostaglandin production and reduce acid secretion, tannins that can be used to protect gastric mucosa. Objective: The purposes of this experiment were to determine the gastroprotective effect and effective dose of ethanolic extract of mahkota dewa fruit (EEMDF) on gastric mucosa induced by acetosal. Method: EEMDF extracted by maceration method. 35 rats divided into 7 groups: normal group; induced group; control group CMC-Na; positive control group; EEMDF groups 100, 200, and 400 mg/kg bw. All groups were given treatments for 7 days except induced group. On sixth day, rats were fasted for 36 hours, then given induction of acetosal. 10 hours later, animal sacrificed, stomach taken for parameter examination. Result: Phytochemical screening show that EEMDF contains secondary metabolites, such as flavonoids, tannins, saponins, alkaloids, glycosides. EEMDF 100, 200, and 400 mg/kg bw have been proven to reduce ulcer numbers, ulcer scores, repair epithelial cells, increase gastric pH, and total acidity. EEMDF 100, 200 and 400 mg/kg bw have gastroprotective effect shown by ulcer inhibitions were 39%, 40.61%, and 50.59% respectively, which were not significantly different from sucralfate, 44.98%. Conclusion: The results of this experiment could be concluded that EEMDF 100, 200, and 400 mg/kg bw had gastroprotective effects in rats that were induced by acetosal by the same ulcer inhibition percentage as sucralfate. Keywords: Phaleria macrocarpa, gastroprotective, induced by NSAID. viii Universitas Sumatera Utara DAFTAR ISI HALAMAN SAMPUL ............................................................................................ i HALAMAN JUDUL ............................................................................................... ii HALAMAN PENGESAHAN ................................................................................ iii KATA PENGANTAR ........................................................................................... iv HALAMAN PERNYATAAN ORISINALITAS .................................................. vi ABSTRAK ........................................................................................................... vii ABSTRACT .......................................................................................................... viii DAFTAR ISI .......................................................................................................... ix DAFTAR GAMBAR ............................................................................................. xi DAFTAR TABEL ................................................................................................. xii DAFTAR LAMPIRAN ........................................................................................ xiii BAB I PENDAHULUAN ........................................................................................ 1 1.1 Latar Belakang ................................................................................................... 1 1.2 Perumusan Masalah ........................................................................................... 4 1.3 Hipotesis Penelitian ............................................................................................ 4 1.4 Tujuan Penelitian ............................................................................................... 4 1.5 Manfaat Penelitian ............................................................................................

    CHAPTER II LITERATURE REVIEW 2.1. The Immune System The Immune system is a form of body defense against the antigens such as infectious agents and malignancies. This system recognizes, processes, and then eradicates antigens. Based on the specification and memory, the immune system defense is classified into two arms, the innate and adaptive immunity. Both the systems share the coordination and develop a well-adjusted mechanism to eradicate the pathogens.1 Innate immunity is known as non-specific immunity. It is defined inasmuch of its ability to eradicate antigens at first line without previously exposed to this specific antigen. This type of immune system is consisted of epithelial barriers, molecules (complement system, C-reactive proteins) and cells of innate immunity such as NK cell, neutrophils, basophils, eosinophils, and monocytes-macrophages. Epithelial barriers are mucosal lining or skin that cover the body and protect with their intact lining. They are the very first barriers that need to be passed by the antigens before invading the host. Complement system consists of soluble proteins that interact one to another resulting in microbial cell wall lysis.3 C-reactive proteins (CRPs) are the same soluble proteins, which are secreted by the liver in response to macrophages cytokines interact with the cell 8 9 walls of several pathogens such as C-polysaccharides of Pneumococcus (Streptococcus pneumoniae).15 Phagocytes of innate immunity are the first cellular responses that encounter the pathogens. The cells are equipped with the pattern recognition receptors (PRRs), phagocytic capability, intracellular killing and some of them are able to present the antigens to the other immune cells, or also known as Antigen- Presenting cells (APCs).

E-Mail: [email protected], Mob: +91 9666 55 221 Abstract Herbs have always been the principal form of medicine in India. Medicinal plants have curative properties due to the presence of various complex chemical substances of different composition, which are found as secondary plant metabolites in one or more parts of these plants. Plants have been used for thousands of years to flavour and conserve food, to treat health disorders and to prevent diseases including epidemics. The knowledge of their healing properties has been transmitted over the centuries within and among human communities. Active compounds produced during secondary vegetal metabolism are usually responsible for the biological properties of some plant species used throughout the globe for various purposes, including treatment of infectious diseases. In recent years, the utilization of certain medicinal plants as therapeutic agents has drastically increased. Phaleria macrocarpa (Scheff.) Boerl is frequently used in traditional medicine. Phaleria macrocarpa, commonly known as Mahkota dewa is a medicinal plant that is indigenous to Indonesia and Malaysia. Extracts of P. macrocarpa have been used since years in traditional medicine that is evaluated scientifically as well.
