Furfurol(Furfudol), a new anthelmintics, was administered to 7 adults and 21 children (6-12 years old) in total amounts of 15.6 mg(base) for 1 to 3 days. It has proven to be effective against hookworms. The anthelmintic effect against hookworms with a single dose of 15.6 mg of furfurol was similar to that of a single dose of 2.5 gm of bephenium hydroxynaphthoate. However, when a total of 15.6 mg of the base was given to both children and adult, the side reactions were so mild that the drug can be administered for therapeutic regimens in mass treatment. Minor abdominal discomfort was the only common side effect. This is the primary advantage of furfurol as compared with bephenium hydroxynaphthoate. These results have indicated that furfurol is safe in therapeutic dosage and is an effective agent to treat patients infected with hookworms.

This study was undertaken to evaluate the effects of health education and anti-Clonorchis campaign conducted in Kyungpook Province and to compare the prevalence of Clonorchis sinensis among the residents in the same areas for the period 1964-1976. Both surveys were made on all age groups of residents ranging from 0 to over 60 years of age. They were examined using primarily intradermal tests with Clonorchis and Paragonimus antigens and followed by stool examinations. The definitive diagnosis of clonorchiasis was made on the recovery of Clonorchis eggs from the stools. A marked reduction in the prevalence was encountered in the youngest age group, but there is no significant difference in the older age groups. The overall prevalence rate for clonorchiasis was reduced from 27.7 to 19.6 per cent in a period of 10 years. It is found that clonorchiasis is less prevalent in Kyungpook Province than it was a decade ago and it continued to decline.
