Changes of respiratory function on urine volume, renal AQP1, and AQP2 in mice with bronchial asthma and effects of lung-diffusing herb Platycodon grandiflorus (JACQ.) A.DC.

Changes in respiratory function in BA model mice can affect how the lung regulates water pathways. Platycodon root diffusing the lung can ameliorate the respiratory-function and pathologic changes in the lung tissues of BA model mice, but also regulate urinary output and renal expression of AQP1 and AQP2.
