INFECTION-PROTECTING AGENT

摘要

PROBLEM TO BE SOLVED: To provide an infection-protecting agent for inhibiting the invasion of pathogenic bacteria participating in the crises and serious states of colds or the like and for inhibiting the adhesion of the pathogenic bacteria to epithelial cells to prevent the infections of such as upper and lower respiratory tract infections. SOLUTION: This infection-protecting agent comprises amylase. A bacterium adhesion inhibitor comprises amylase. A composition for oral cavities contains amylase. Thereby, the adhesion of the bacteria to the epithelial cells can be inhibited to protect the infection of the upper and lower respiratory tracts with the bacteria. COPYRIGHT: (C)2004,JPO
