Abstract

<p>Abstrak<br />Akumulasi logam berat dapat meningkatkan senyawa oksigen reaktif dan menekan kadar antioksidan esensial dalam tubuh. Vitamin C merupakan antioksidan non enzimatis, senyawa alami yang bersifat antioksidan kuat dan pengikat radikal bebas. Penelitian ini bertujuan untuk mengetahui Efek Pemberian Vitamin C Terhadap Aktifitas Katalase Hati Tikus Galur Wistar Yang Terpapar Ion Pb, dilakukan di laboratorium Farmakologi Fakultas Farmasi dan Biokimia Fakultas Kedokteran Unand Penelitian dilakukan terhadap tikus galur wistar, berumur tiga bulan, berat badan + 200 gram, yang berjumlah 28 ekor. Didapatkan bahwa pemaparan ion Pb 0,05 mg/g BB/hari selama empat minggu dapat menurunkan aktifitas katalase hati tikus galur wistar. Penambahan vitamin C 0,05mg/g BB/hari dan 0,075 mg/g BB/hari pada tikus yang terpapar ion Pb menunjukan peningkatan aktifitas katalase hati tikus galur wistar. Berdasarkan uji T berpasangan terdapat perbedaan yang signifikan antara aktifitas katalase hati tikus galur wistar yang tidak terpapar ion Pb dengan terpapar ion Pb (p = 0,005 atau p &lt; 0,05). Pemberian vitamin C pada tikus galur wistar yang terpapar ion Pb secara statistik dengan uji one way Anova tidak terdapat pengaruh yang signifikansi (p = 0,143 atau p &gt; 0,05). Namun pada post hocx test terdapat pengaruh pemberian vitamin C 0,075 mg/g BB/hari pada tikus yang terpapar ion Pb, dengan p = 0,053 atau p = 0,05.<br />Kata kunci: Aktifitas Katalase, Vitamin C, Ion Pb</p><p>Abstract<br />The presence of heavy metals such as Pb can produce a free radical, it will also be able to decrease the availability of the body's antioxidants. Vitamin C is a non-enzymatic antioxidants, natural compounds that are strong antioxidants and free radical binding. This study to determine the Effect of Vitamin C to catalase activity of rat-wistar strain-liver. The purpose of which Exposed Pb ions, carried out in the laboratory of Pharmacology of the Faculty of Pharmacy and Biochemistry Faculty of Medicine Unand. Research conducted on wistar strain rats, three months old, weight + 200 grams, which totaling 28 tails. The result was exposure of Pb ions 0.05 mg / g BW / day for four weeks decreases catalase activity rat’s-wistar-strain liver. The addition of vitamin C 0,05mg / g BW / day and 0.075 mg / g bw / day in exposed rats to Pb ions showed increased levels of catalase activity rat’s-wistar-strain liver. The result of the paired t test there was difference significantly between liver catalase activity rat’s-wistar-strain liver were not exposed to Pb ions (p = 0.005 or p &lt; 0.05). Administration of vitamin C were exposed to Pb ion statistically by one-way ANOVA test there was no significant effect ( p = 0.143 or p &gt; 0.05 ) . But in the post hocx test the effect of vitamin C contained 0.075 mg / g bw / day in rats exposed to Pb ions, with p = 0.053 or p = 0.05<br />Keywords: Catalase Activity, Vitamin C, Pb ions.</p
