Bitter melon (Momordica charantia L.) is a plant that used as herbal medicine. It contains bioactive components which have hypoglycemic activity, immunomodulators, cancer chemoprevention, antiviral, antimicrobial, and inhibits oxidative stress and inflammation. The purpose of this study was to assess the degree of liver damage by macroscopic and microscopic examination. The sample consisted of 40 rats divided into 4 groups, Group 1, control group, was only given aquadest and pellets. Group 2-4 were treated with ethanol extract of bitter melon pulp 250 mg/kgbw, 500 mg/kgbw, and 1000 mg/kgbw during 28 days. On the 29th day, the termination was carried out, aspartate and alanin aminotransferase (AST/ALT) being measured, the liver being observed for the macroscopic and microscopic morphology. Kruskal-Wallis test showed there was no significant difference in relative organ weight (p = 0.177), liver macroscopy morphology (p = 0.207). Microscopic observation for liver fibrosis using Metavir scoring system showed highest mean liver fibrosis score in dose 1000 mg/kgbw. Kruskal-Wallis test for microscopic changes showed significantly difference in male rats (p = 0.001) and female rats (p = 0.002). Based on these study, we conclude that ethanol extract of bitter melon pulp at a dose of 250 mg/kgbw, 500 mg/kgbw, and 1000 mg/kgbw affect liver function significantly. But there{\textquoteright}s no subchronic toxicity effect on relative organ weight and macroscopic changes in liver morphology. Otherwise there was subchronic toxicity effect on changes in the microscopic structure of the liver characterized by the formation of fibrosis in the liver portal triad of experimental animals.

Objective: This research elaborated role of alpha mangostin and xanthone on fasting blood glucose, insulin and langerhans islet in alloxan induced diabetic mice. Methods: Fasting blood glucose, insulin and langerhans islet test were conducted using male Mus musculus mice, divided into 10 groups randomly, which were normal, control (alloxan induced only), glibenclamide, various doses of α-mangostin and xanthone (5, 10, 20 mg/kgbw). Mice were treated for 21 days. Overnight-fasted mice (12 h) were sacrificed by cervical decapitation on day 21st, following the ethical norms granted by the ethics committee. Fasting blood glucose and insulin plasma were checked. Pancreatic tissues were excised from sacrificed animals, and then fixed in 10 \% (v/v) neutral buffered formalin. Histologic observations for Langerhans area were performed after staining using Gomori staining method. Results: The effects of alpha mangostin and xanthone on fasting blood glucose different significantly to control, and were not significantly different from glibenclamide and metformin. Increasing alpha mangostin/xanthone dose from 5 mg/kgbw to 20 mg/bw also did not cause significant differences, although the best results were obtained at a dose of 20 mg/kgbw. Insulin plasma analize showed that there were no significant difference between alpha mangostin/xanthone to normal group, except xanthone 10 mg/kgbw. Langerhans area showed significant difference between alpha mangostin/xanthone to control group. But there{\textquoteright}s still had significant difference if we compare to glibenclamid/metformin group. Conclusion: Alpha mangostin and xanthone are two substances that showed antidiabetic effect on fasting blood glucose level, insulin plasma and Langerhans islet.
