The Potency of Ethanolic Extract of Sauropus androgynus (L.) Merr Leaves as Therapeutic herbal of Rats (Rattus norvegicus) Peptic Ulcer Model Induced by Aspirin

Abstract

Peptic ulcer is an erosion of the mucosa gaster and duodenum. Aspirin can increase the activity of ROS in duodenum leading to be oxidative stress condition, followed by the increase expression of TNF-α and changes in the duodenum histopathology. Ethanolic extract from Sauropus androgynus (L.) Merr leaves contains flavonoid compound that act as antioxidants. The research aimed to study the therapeutic effect of Sauropus androgynus (L.) Merr leaves towards the expression of TNF-α and the duodenum histopathology. The study used five groups: the negative control group, the positive control group (peptic ulcer), and three therapeutic groups. Peptic ulcer induced by aspirin 200 mg/kg BW given orally once a day for five days. The therapeutic group (dose 16.2 mg/200 g BW, 32.4 mg/200 g BW, 48.6 mg/200 g BW) administrated orally once a day for fourteen days. Expression of TNF-α were analyzed by ANOVA followed by Tukey test (α=5%) and histopathology description of duodenum were analyzed descriptive qualitative. The result showed that treatment of the ethanolic extract from Sauropus androgynus (L.) Merr leaves at dose 48.6 mg/200 g BW was the effective dosage. The conclusion of this research indicate that ethanolic extract from Sauropus androgynus (L.) Merr leaves can be used as alternative therapy peptic ulcer towards decrease the expression of TNF-α and repair duodenum histopathology such as structure of epithelial duodenum, vile and decrease of inflammatory cell and vascular vasodilatation
