- Bronchial mucosal epithelial secretory cells are scattered in the respiratory tract, particularly in the bronchi, and are said to have the function of secreting airway mucus and to be partially involved in the production of pulmonary surfactant in vivo.
- PSF is a substance mainly composed of phospholipids composed mainly of phosphatidyl choline (also called corin phosphoglyceride; the same applies hereinafter), and many types of PSF have been reported as described below. . According to those reports, PSF generally has the effect of lowering the surface tension of the alveolar gas-liquid interface, maintaining the alveolar cavity physiologically and smoothing the respiratory function of the lungs.
- PSF is useful as a therapeutic agent for asthma because it has a function of stabilizing the bronchi and suppressing allergic bronchoconstriction. It has also been reported.
