Abstrak: This study aims to test the safety and effect of 96% ethanol extract of leaves Wungu (Graptophyllum pictum (L.) Griff) against murine organs (liver and kidney). Security Wungu leaves tested for 3 months with subkronis toxicity methods. Grouping of experimental animals were divided into 4 groups, namely, the 100 mg / kg bb, 500 mg / kg bb, 1000 mg / kg bb and normal. The group was observed and seen the death and his body weight in treatment. Safety testing is conducted for 3 months showed that the leaf Wungu safe and beneficial in adding to the animal life. Experimental animals used in these experiments is that mice with a number of 10 fish per group. Age of mice used is 2 months. The results of death analysis produces data that can not be calculated in the LD 50 because the accretion death at the highest dose while the accretion death a little more at the lowest dose increased. Once that was done histopathologically to see the damage that occurs in the whole body. Safety testing has been conducted shows that 96% ethanol extract of leaves Wungu safe because of the death of mice used for all groups of less than 50%. When examined further conclusions based on data obtained on the histopathology of the life expectancy of mice is more in line with the addition of a large dose of a compound that is used to indicate the possibility of having the ability to increase survival of mice caused 96% ethanol extract of leaves Wungu

Judul: Potensi Ekstrak Etanol Daun Wungu (Graphtophyllum pictum (L.) Griff) pada Tikus Sprague-dawley Diabetes yang Diinduksi Aloksan
Abstrak: High level of glucose in blood can cause Diabetes Mellitus (DM). This desease can be treated by either chemical or herbal medicine. One of herbal plant which is expected to heal the desease DM is Wungu leaves. Glucose measurement was conducted to 7 group, normal group (K-1), negative control (K-2), positive control (K-3), ethanol extract of wungu leaves 25 mg/kg bb (K-4), 50 mg/kg bb (K-5), 100 mg/kg bb (K-6), 200 mg/kg bb (K-7). The measurement was conducted in 2 phase namely treatment phase, to determine the effect of ethanol extract of Wungu leaves on DM and post-treatment phase which is to determine the effectiveness of extract of Wungu leaves in dcreasing glucose in blood. The sample animal that is used is Sprague-dawley ratswhich is weighting ≥ 200 gram, the experimental is carried out for 21 days. The result shows that the extract of Wungu leaves effect on decreasing glucose level is blood of diabetes rats. The decreasing of glucose strat from > 200 mg/dL in day 4 to < 200 mg/dL in day 14. Post-treatment phase shows that K-3, K-5, and K-6 decrease significiently. Decreasing on K-3 indicate that glibenklamid is working good in decreasing glucose level in DM rats blood, glucose K-5 on 15th minute is lower than K-6, so it can be conclude that K-5 is more effective in decreasing glucose level on DM rats.
