宣肺利水法对肺源性心脏病大鼠心肺相关指标的改变

摘要

This study was aimed to diffuse the lung and promote urination for the observation of cardiopulmonary re-lated index change of cor pulmonale rats to further explore the treatment effect on the pulmonary function, pulmonary arterial hypertension (PAH) and the influence of right heart hypertrophy of rats, in order to further illustrate the ef-fect of diffusing the lung and promoting urination for cor pulmonale. Sixty Wistar rats were randomly divided into the control group, model group and Xiao-Qing-Long decoction (XQLD) group with 20 rats in each group. The AniRes2003 animal lung function analysis system was applied to measure the pulmonary function of rats. And the multi-guide physiological recorder was used in the recording of the pulmonary artery pressure of rats. The conven-tional weighing method was applied to calculate and obtain the change of right heart hypertrophy. The results showed that compared to the control group, symptoms in the model group became severe obviously, which include reduced activity, slow movement and occasional airway sputum sound, and the right heart hypertrophy index of the model group increased obviously (P < 0.01). Compared to the model group, the pulmonary function and pulmonary artery pressure of the XQLD group have obvious difference (P< 0.05). It was concluded that to diffuse the lung and pro-mote urination can effectively improve the pulmonary function, PAH and the right heart hypertrophy index of rats with cor pulmonale (fluid retention). The effect of this method is definite in the treatment of cor pulmonale.%目的：运用宣肺利水法观察肺源性心脏病大鼠心肺相关指标的改变，研究该法对大鼠肺功能、肺动脉高压及右心肥厚的影响，进一步探讨宣肺利水法对于肺源性心脏病的疗效。方法：60只Wistar大鼠，随机分为对照组、模型组和小青龙汤组；使用AniRes2003动物肺功能分析系统测定大鼠肺功能，运用多导生理记录仪记录大鼠肺动脉压力，并采用常规称重法计算右心肥厚的改变。结果：与对照组比较，模型组症状均明显加重，活动量减少，行动迟缓，偶可闻及气道痰鸣音，且模型组右心肥厚明显升高（P<0.01）；与模型组比较，小青龙汤组大鼠肺功能和肺动脉压有明显差异（P<0.05）。结论：宣肺利水法能够有效改善肺源性心脏病（支饮）大鼠的肺功能、肺动脉高压及右心肥厚指标，该法对于肺源性心脏病的疗效明确。
