Vitamin D3 for initial dosage (700.000 IU/kg) was given in the first day, and repeated every four weeks 300.000 IU/kg by using sondage. There are 3 groups of rats; 8 weeks group (P1), 12 weeks group (P2), and control group (P0). For control group, the animal only fed by standard food without giving vitamin D3. Histopathology evaluation based on Histological activity by Metavir system, which grade into none, mild, moderate and severe. Results: For control group, there are 60% samples with mild activity score and 40% with moderate activity score.
