Abstract: Objective To observe the effect of Lobelia alkaloids on pulmonary vascular remodeling of pulmonary arterial hypertension (PAH) rat model and to explore its mechanism. Methods Twenty-four male Wistar rats were randomly divided into normal control group, model group and Lobelia alkaloids group. PAH rat models were established by giving monocrotaline (MCT) intraperitoneally, and the rats were given Lobelia alkaloids by intragastric administration for 4 weeks. HE staining, ELISA and immunohistochemical methods were used to study pulmonary morphological changes, endothelin-1 (ET-1) level in plasma and endothelin receptor A (ETA) expression in lung tissue. Results Lobelia alkaloids could significantly alleviate pulmonary artery remodeling and decrease the ET-1 level in plasma and ETA protein expression in lung tissue of PAH rat model. Conclusion Lobelia alkaloids can inhibit significantly pulmonary artery remodeling of PAH rat model induced by MCT which may be related to the decreased ET-1 level in plasma and ETA protein expression in lung tissue.

Key words: Pulmonary vascular remodeling, Endothelin-1, Lobelia alkaloids, Pulmonary arterial hypertension, Endothelin receptor A
