Abstract

Introduction: The soursoup leaves extract (Annona muricata) has widely been used as traditional medicine for cancer. No studies have been conduct to investigate the safety of the extract. Objectives: The purpose of the study was to investigate the acute oral toxicity test of soursoup leaves extract (Annona muricata) on Swiss mice’s liver and kidney.Methods: Twenty four mice were divided into 4 groups. Group I was control group, while group II-IV was given soursoup leaves extract as single dose orally via sonde. The mice were obsereved until day 7 to determine the LD50 and at the end were terminated to collect the liver and kidney. The organs later were made into histopathology slides. The slides read with light microscope. The data analyzed with ANOVA and was considered significant at p<0.05.Results: All mice were alive during the 7 days observation and no mice showing the toxic spectrum after the dosing. Microscopically, no damage on the liver and kidney organ among the groups.Conclusion: The LD50 of soursoup leaves extract is more than 2000 mg/kgBW. This result indicate that the extract is practically non toxic and do not damage the liver and kidney.

Abstract

Introduction: Burn therapy is generally done using a burn ointment. However, honey can also be used as an alternative treatment for burns. Honey contains active flavonoid as an antioxidant and hydrogen peroxide which can stimulate fibroblasts proliferation also angiogenesis on burn healing phase.Objective: to determine the effect of honey in second degree burn healing from angiogenesis and the number of fibroblasts on Wistar rats. Methods: This research used a posttest only controlled group design on 15 rats with random selection and divided into 3 groups: H-G was given honey, B-G was given Bioplacenton®, N-G without any treatment after burn was induced. Rats were given a second degree burn in a size of 2 cm x 2cm on the back area and were treated twice a day for 14 days. Burn healing was measured by calculating the observation results of microscopic VEGF expression, the number of neovascularization, and the number of fibroblasts. Hypothesis analysis used Annova post hoc LSD and Mann-Whitney.Results: The highest mean in VEGF expression and the number of neovascularization was obtained from group B-G followed by group H-G and group N-G. Significant differences in the number of neovascularization between group B-G with group N-G, p<0.05.Conclusion: Honey can provide a healing effect on the second degree of burns in Wistar rats in terms of the number of neovascularization as well as Bioplacenton®
