In the present study, to provide experimental basis for the clinical application of SLPCD in treating asthma and to explore its mechanisms of action, using OVA-induced allergic asthma mouse model, the anti-inflammatory effects of SLPCD were investigated by histological examination, enumeration of immune cells in bronchoalveolar lavage fluid (BALF), quantization of total IgE in serum, cytokine in BALF, and the mRNA expression of cytokine in lung tissues. The gene discussed is IGHE; the disease is asthma.
