Here we investigated whether astragaloside IV could suppress the progression of airway inflammation, airway hyperresponsiveness, and airway remodeling in a murine model of chronic asthma. BALB\/c mice sensitized to ovalbumin (OVA) were chronically challenged with aerosolized OVA for 8\u00a0weeks. Astragaloside IV was orally administered at a dose of 50\u00a0mg\u00b7kg<jats:sup>\u20131<\/jats:sup>\u00b7day<jats:sup>\u20131<\/jats:sup> during each OVA challenge. Astragaloside IV treatment resulted in significant reduction of eosinophilic airway inflammation, airway hyperresponsiveness, interleukin (IL)-4 and IL-13 levels in bronchoalveolar lavage fluid, and total immunoglobulin E levels in serum. Furthermore, astragaloside IV treatment markedly inhibited airway remodeling, including subepithelial fibrosis, smooth muscle hypertrophy, and goblet cell hyperplasia. In addition, the expression of transforming growth factor-\u03b21 in the lung was also reduced by astragaloside IV. These data indicate that astragaloside IV may mitigate the development of characteristic features in chronic experimental asthma. <\/jats:p>","DOI":"10.1139\/y08-053","type":"journal-article","created":{"date-parts":[[2008,7,2]],"date-time":"2008-07-02T15:22:42Z","timestamp":1215012162000},"page":"449-457","source":"Crossref","is-referenced-by-count":62,"title":["Inhibitory effects of astragaloside IV on ovalbumin-induced chronic experimental asthma"],"prefix":"10.1139","volume":"86","author":[{"given":"Qiang","family":"Du","sequence":"first","affiliation":[{"name":"Department of Respiratory Medicine, The First Affiliated Hospital, Nanjing Medical University, 300 Guangzhou Road, Nanjing 210029, China."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhen","family":"Chen","sequence":"additional","affiliation":[{"name":"Department of Respiratory Medicine, The First Affiliated Hospital, Nanjing Medical University, 300 Guangzhou Road, Nanjing 210029, China."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lin-fu","family":"Zhou","sequence":"additional","affiliation":[{"name":"Department of Respiratory Medicine, The First Affiliated Hospital, Nanjing Medical University, 300 Guangzhou Road, Nanjing 210029, China."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Qian","family":"Zhang","sequence":"additional","affiliation":[{"name":"Department of Respiratory Medicine, The First Affiliated Hospital, Nanjing Medical University, 300 Guangzhou Road, Nanjing 210029, China."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mao","family":"Huang","sequence":"additional","affiliation":[{"name":"Department of Respiratory Medicine, The First Affiliated Hospital, Nanjing Medical University, 300 Guangzhou Road, Nanjing 210029, China."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kai-sheng","family":"Yin","sequence":"additional","affiliation":[{"name":"Department of Respiratory Medicine, The First Affiliated Hospital, Nanjing Medical University, 300 Guangzhou Road, Nanjing 210029, China."}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"155","reference":[{"key":"rg1\/ref1","doi-asserted-by":"publisher","DOI":"10.1378\/chest.101.4.916"},{"key":"rg2\/ref2","doi-asserted-by":"publisher","DOI":"10.1164\/rccm.200209-1030OC"},{"key":"rg3\/ref3","doi-asserted-by":"crossref","first-page":"1720","DOI":"10.1164\/ajrccm.161.5.9903102","volume":"161","author":"Bousquet J.","year":"2000","journal-title":"Am.
