Allergy diseases tend to increase with variety of clinical manifestations. To date, pharmacotherapy do not treat the underlying disease. Many researches concerned to study new approach of allergy therapy which need allergy mouse model for evaluation. This study was aimed to compare the effectiveness of two treatment methods by using ovalbumin for allergy sensitization. This study was conducted in PT.Bimana Indomedical animal facility Bogor on June until September 2016. Six mice were divided into 2 groups. First group was sensitized by ovalbumin 100ug subcutaneous (sc) day-0, 50 ug intra peritoneal (ip) day-14 and 100 ug intranasal (in) day-21. Second group was sensitized by ovalbumin 10 ug ip day-0 and day-7, 10 ug in day-21, 22, and 23. Body weight, hematology parameters (red blood cells, white blood cells, hemoglobin and hematocrit) and total IgE concentration of day-0 (pre-treatment) and day 24 (post-treatment) were measured. The results showed that there was an increase of mice body weight of both treatment group, while hematology changes of pre and post treatment were not significantly different (paired t-test). Whereas the increase in total IgE pre and post treatment was significantly different between the two groups (paired t-test). In conclusion, the second allergy sensitization method is better than the first allergy sensitization method.
