ABSTRACT
<p><b>OBJECTIVE</b>To study and discuss the effect and mechanism of Hirsutella sinensis mycelium (HSM) on idiopathic pulmonary fibrosis in rats.</p><p><b>METHOD</b>Forty Wistar rats were divided into five groups the normal control group, the model control group, the high-dose group (1.0 g x kg(-1) HSM), the low-dose group (0.5 g x kg(-1) HSM), and the positive control group (10 mg x kg(-1) hydrocortisone). In addition to rats in the normal control group, the pulmonary fibrosis model was established by injecting 5 mg x kg(-1) bleomycin into rat tracheas for consecutively 28 days, in order to observe their lung function, lung tissue hydroxyproline, cytokines and pathology.</p><p><b>RESULT</b>After rats were administered with HSM, 0.5 g x kg(-1) and 1.0 g x kg(-1) HSM could significantly decrease lung index and hydroxyproline content (P<0.01), while notably improving pulmonary function, alveolus inflammation and fibrosis degree (P<0.05, P<0.01); 1.0 g x kg(-1) HSM could decrease significantly protein expressions of TNF-alpha, IL-1beta and TGF-beta1 in lung tissues, while increasing significantly protein expressions of IFN-gamma (P<0.05).</p><p><b>CONCLUSION</b>HSM have better effect in treating idiopathic pulmonary fibrosis in rats. Its treatment effect and mechanism are related to the regulation of TNF-alpha, IL-1beta and TGF-beta1 and IFN-gamma imbalance.</p>
