Abstract
An examination of the mass extermination of helminths was conducted with the children of a primary school at Shizuoka City. The result of the experiment on using Macsanto, a helminthic, was as follows.
1. This experiment on the mass extermination of helminths was very useful not only for the helminth prevention of the school children but also for hygienic guidance and education of their families at homes over the district. The cooperation of the families did much toward the success of this experiment.
2. Macsanto, the mixture of Macnin and Santonin, used in this experiment was so effective as to decrease the positive reaction rate to a eighth with the first dosage, and no ill effect was produced with every dosage.
3. The cost of the medicine was inexpensive to use it frequently.
4. It was convinced through my experiences in the past and the results of the experiment that mass extermination can be achieved for the most part by giving them a reasonable quantity of the said mixture continuously for two days. Accordingly, I am going to recommend this medicine as a harmless helminthic to all of the primary and the middle schools at Shizuoka City.
