초록

Objectives : The objectives of this study is to develop a mouse model similar to Taeeum-type by inducing Lung fibrosis with bleomycin, and to determine adequate concentration of bleomycin. Methods : The subjects were divided into six groups: normal, obesity induced group, and bleomycin administered 0.015U, 0.03U, 0.06U, and 0.09U(U/100g bw) concentrations respectively. Each concentration of bleomycin was dissolved in distilled water, and administered through Intra-Nazal-Trachea injection method. Food intake and body weight were measured at regular time weekly. At the end of the experiment, blood was gathered by cardiac puncture for biochemical examinations, organs were removed for histological examinations, and weigh and mRNA genes was analyzed. Result : Mice administered with bleomycin at 0.015U and 0.03U showed body and fat weight gain, and increased blood total cholesterol, LDL-cholesterol, glucose, and free fatty acid level. Fat related genes also showed higher level than the control group. Obesity was most strongly induced in the mice administered with 0.03U of bleomycin. On the other hand, when bleomycin was administered at concentrations above 0.06U, a model of obesity mouse was not created due to rapid emphysema inflammation and weakness. Conclusions : Mice were most vulnerable to obesity when bleomycin was administered at a concentration of 0.3 to cause liver damage. Bleomycin concentration over 0.06U did not cause obesity-induced mice, due to severe damage in liver.
