A Study of the Effect on Obesity in Taeeumin Animal-experimental Model Induced Lung Fibrosis with Bleomycin

The objective of this study is to develop a taeeumin animal-experimental model induced lung fibrosis with Bleomycin and evaluate the effect on obesity in this animal-experimental model. The subjects were divided into 3 groups : normal group, high fat diet(HFD) control group, and HFD group administered with bleomycin(n=10 per group). To develop taeeumin animal-experimental model with reduced respiratory metabolism, 8-week-old C57BL/6 mice were administered with 0.03ml solution of bleomycin 1U/ml dissolved in distilled water, intratracheal(IT), once. Then, the HFD control group and the experimental group were fed with high fat diet for 6 weeks. Airway hyperresponsiveness(AHR) to methacholine was measured at the 1st and 3rd week after bleomycin was administered. Food intake and body weight were measured at regular time weekly. After the final experiment, blood was gathered by cardiac puncture for bloodchemical examination and organs(liver, fatty tissue) were remoed, weighted, and mRNA was analyzed. the gene expression increased and energy metabolizing gene mRNA of decreased, it was found that Taeeuim animal-experimental model is susceptible to metabolic syndrome and cardiovascular diseases.
