| Research Abstract |
Causes of aspiration pneumonitis are oral bacteria et al. Saliva proteins reduce oral bacteria et al, and those expression and secretion are regulated by cAMP, and cAMP are controlled by phosphodiesterase (PDE).In rat submandibular gland main PDEs are PDE3 and PDE4. In isolated rat submandibular acini cells PDE3 was expressed, but not in duct cells. Myoepithelial cells were found in both cells. There were no change in submandibular gland of PDE3 knock out mouse. PDE4A and PDE7B were wxpressed in submandibular gland. It is suggested that each PDE regulated the expression and secretion of saliva protein.
