Gout merupakan penyakit metabolik yang menyebabkan kadar asam urat darah melebihi batas normal. Tujuan dari penelitian ini untuk menentukan nilai LD50 ekstrak air herba Akar Kucing ( Acalypha indica Linn.) dan pengaruhnya terhadap kadar asam urat dalam darah. Pada penentuan nilai LD50, 20 ekor mencit dibagi secara acak menjadi 4 kelompok. Mencit-mencit ini diamati selama 24 jam. Hasil menunjukkan bahwa nilai LD50 dari ekstrak air herba Akar Kucing adalah 8,1329 g/kg bb. Pada uji khasiat ekstrak air herba Akar Kucing digunakan 36 tikus jantan yang dibagi menjadi enam kelompok. Kelompok I, II dan III masing-masing diberi ekstrak air herba Akar Kucing dengan dosis 1,35 g/200 g bb; 2,7 g/200 g bb; and 5,4 g/200 g bb per hari. Sedangkan kelompok IV, V dan VI merupakan kelompok kontrol pembanding (alopurinol), perlakuan dan normal. Perlakuan diberikan selama 7 hari. Pada hari ke-8, semua kelompok (kecuali kontrol normal) diinduksi dengan kalium oksonat satu jam sebelum perlakuan. Dua jam setelah diinduksi, sampel darah diambil dan diukur. Penetapan kadar asam urat menggunakan metode kolorimetri enzimatik. Hasil menunjukkan dosis 2,7 g/200 g bb dan dosis 5,4 g/200 g bb per hari dapat menurunkan kadar asam urat secara bermakna (p<0,05).
Gout is a metabolic disease that can cause much uric acid level in blood. The purpose of this research was to determinated LD50 level in the water extract of Akar Kucing (Acalypha indica Linn.) herb and it influence to uric acid level. In determinate LD50, 20 mice were randomly divided into 4 dose groups. The dosed animals were observed during 24 hour. Result show that LD50 of the water extract of Akar Kucing herb is 8,1329 g/kg body weight. In the observation about the influence of the water extract of Akar Kucing herb, 36 male rats were randomly divided into 6 groups. Group I, II, and III received 1,35 g/200 g; 2,7 g/200 ; and 5,4 g/200 g body weight per day of the water extract of Akar Kucing herb. While group IV, V, and VI are group comparing (alopurinol), treatment, and normal control. This treatment was given for 7 day. In the 8 day, all group (except normal group) were injected with potassium oxonate 1 hour before drug administration. After 2 hours from injection of potassium oxonate, blood samples were collected and determinated. The determination was used colorimetric enzymatic method. Result showed that dose 2,7 g/200 g and dose 5,4 g/200 g rat per day has significant effect to reduce uric acid level (p<0,05). |
