    摘要: The invention provides a measure that can readily prevent arthropod-borne diseases such as malaria that are contracted by 3 to 5 hundred million people worldwide yearly and that cause death of as many as 1.5 to 2.7 million people. By spraying in advance on the skin an arthropod-borne disease preventive agent or the like comprising chlorine dioxide as an effective component thereof, it is possible to provide repelling effect against arthropods such as infected mosquitoes that bear malaria protozoa and also to prevent biting of the skin by the arthropod, thus reducing contraction of the arthropod-borne diseases.

    摘要: An intestinal juice level regulator comprising, as the active ingredient, creosote or phenolic derivatives constituting creosote. As having the activities to promote the absorption of intestinal juices and/or to retard the secretion of intestinal juices, the active ingredient lowers the intestinal juice level in intestines. As the phenolic derivatives, usable are one or more of guaiacol, creosol, phenol, cresol and xylenol. The regulator is especially effective for retarding the hypersecretion of intestinal juices to be caused by heat-labile or heat-stable enterotoxin of enterotoxigenic Escherichia coli.
