Abstract

ABSTRACT Atherosclerosis is one cause of death. The thickening of the arterial walls which form atherosclerotic plaque can cause a blockage of the artery lumen and lead to thrombosis and blood flow. VCAM-1 activation causes increased adhesion of monocytes to endothelial walls and foam cell formation which is the key to the occurrence of atherosclerosis. Diplazium esculentum contains antioxidants and is able to inhibit the activation of VCAM-1. This study aimed to determine the effect of vegetable fern extract on the expression of VCAM-1 as an anti-atherogenic effect and the effective dose required. Experimental studies using randomized post test only control group design. Samples were grouped into 7 groups, namely K, KN, P1, P2, P3, P4, and P5. All group except K induced by atherogenic diet ang followed by the granting of vegetable fern extracts of 300 mg/kgBW in P1 groups, 600 mg/kgBW in P2 groups, 900 mg/kgBW in P3 groups, 1200 mg/kgBW in P4 groups, and 1500 mg/kgBW in P5 groups. The results showed a correlation between the dose of the extract given by the expression of VCAM-1, the greater the dose given VCAM-1 will be further hampered. The effective dose in rats was 2707, 19 mg/kg, this dose is equivalent to 4 kg of fresh vegetables fern in humans. Keywords: Atherosclerosis, Vegetable Fern Extract, VCAM-1  ABSTRAK Aterosklerosis merupakan salah satu penyebab kematian. Penebalan dinding arteri yang membentuk plak aterosklerosis dapat menyebabkan penyumbatan lumen arteri dan mengakibatkan trombosis dan gangguan aliran darah. Aktivasi VCAM-1 menyebabkan peningkatan perlekatan monosit pada dinding endotel dan pembentukan foam cell yang merupakan kunci terjadinya aterogenesis. Diplazium esculentum mengandung senyawa aktif yang bersifat antioksidan dan mampu menghambat aktivasi VCAM-1. Penelitian ini bertujuan untuk mengetahui pengaruh ekstrak pakis sayur terhadap ekspresi VCAM-1 sebagai efek antiaterogenik dan dosis efektif yang diperlukan. Studi eksperimental menggunakan randomized post test only control group design. Sampel dikelompokkan menjadi 7 kelompok, yaitu K, KN, P1, P2, P3,P4, dan P5. Tiap kelompok diinduksi diet aterogenik dilanjutkan dengan pemberian ekstrak pakis sayur sebesar 300 mg/kgBB, 600 mg/kgBB, 900 mg/kgBB, 1200 mg/kgBB, dan 1500 mg/kgBB. Hasil penelitian menunjukkan terdapat hubungan antara dosis ekstrak yang diberikan dengan ekspresi VCAM-1, semakin besar dosis yang diberikan ekspresi VCAM-1 akan semakin terhambat. Dosis efektif pada tikus adalah 2707, 19 mg/kgBB, dosis ini setara dengan 4 kg pakis sayur segar pada manusia. Kata Kunci: Aterosklerosis, Ekstrak Pakis Sayur, VCAM-1

Abstract

ABSTRACT Methanol poisoning is a serious problem due to its high mortality and revalence of health sequelae among survivors. Death from methanol poisoning has been reported in 8-36% and permanent vision loss has been observed in 20- 0% of acute trauma survivors. Formic acid that builds up in the optic nerve can disrupt the visual system and cause optic neuropathy. Vision loss is painless and usually occurs in both eyes within one to three days. This Systematic Review based on Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) protocol. This protocol has administered in The International Prospective Register of Systematic Reviews (PROSPERO) database. The literature showed visual acuity and funduscopic examinations of methanol induced optic toxic neuropathy and high-dose steroid, erythropoietin and antioxidant as the therapy. Methanol poisoning is a serious problem due to its high mortality and prevalence of health sequelae among survivors. Pericapillary retinal edema and optic disc edema after blurred vision or "snowfield" vision, visual hallucinations, dense central fibroids, photophobia, peripheral constriction of the visual field, and decreased visual acuity even total blindness as a symptom can be found. Prevention of formic acid formation is the main steps of treatment. Keywords:Methanol, Literature Review, ManagementABSTRACT Methanol poisoning is a serious problem due to its high mortality and revalence of health sequelae among survivors.
