Ten cases infected with Taenia saginata were treated with Bithionol, 2, 2' thiobis (4,6-dichlorophenol) which is well known as an excellent anthelminthhic against paragonimiasis and their follow-up studies were carried on within 3 to 12 months after treatment. Bithionol, 50 mg dose per kg of body weight was divided into two equal dose and administered orally in 30 minutes intervals. Three hours later, this was followed with a sodium sulfate or magnesium sulfate purge. The strobilas without scolices were found in the stools after the medication and the follow-up studies have shown the complete deworming in all cases. It is well tolerated, toxic effects being uncommon and when present, limited to mild gastro-intestinal disturbances.

A complete but abnormal form of Taenia worm was obtained from an 18-year-old male student in Cheju Island, Korea, which has been known as a heavy endemic area of Taenia saginata and few of T. solium. There was an apical hookless eminence in the scolex, longitudinal white line along the middle portion of entire strobila, double genital pores and several lateral buddings from the strobila. It was considered an abnormal form of Taenia species, probably T. saginata.

A 77-year old man living in Kyunggi-Do, Korea was surgically treated at Seoul National University Hospital on April 1981, because of acute abdomen. At laparotomy, a 1.77m long adult Taenia saginata was found both in gallbladder and in common bile duct to cause acute gangrenous cholecystitis. The relevant literature were reviewed and possible mechanisms of the disease were discussed.

In an attempt to investigate the antigen-antibody relations and the value of immunodiagnosis for several helminths, Ouchterlony tests and immunoelectrophoreses were carried out. Taenia saginata, Cysticercus sp. of cestodes, Clonorchis sinensis, Fasciola hepatica and Paramphistomum sp. of trematodes,and Ascaris suum of nematodes were used as antigens. On the other hand, antisera were obtained by injecting 0.5 ml each of the above antigens and the same amount of complete Freund's adjuvant into rabbits ten times at an interval of one week. The result obtained in this study are as follows: A larger number of precipitin arcs were demonstrated in homologous antigen-antibody reactions than in heterologous antigen-antibody reactions both in Ouchterlony tests and immunoelectrophoreses. Gross reactions were observed between the different species of the same class, but no cross reactions were noticed when the classes were different with one or two exceptions, such as between T. saginata, F. hepatica and A. suum. In A. suum, the difference between the male and female was more distinct in Ouchterlony test and immunoelectrophoresis than in the examination of organs such as genital organ and coeliac fluid. Immunoelectrophoresis revealed specific arcs and higher sensitive reaction than Ouchterlony test, and was considered to be a more valuable method for identifing species and immunological diagnosis.

The effects of various digestive enzymes, fresh biles, and bile acids on the hatching and activation of the eggs of Taenia saginata, T. pisiformis, T. solium, Hymenolepis nana, and Moniezia expansa have been investigated. On the basis of the results of the present study author attempted to elucidate the specificity of host-parasite relationships in the tapeworm infections. The results were summarized as follows: In case of the ova of T. saginata, pretreatment with artificial gastric juice before contact of intestinal juice is required to bring the disintegration of the embryophore and activation of the embryo. However the ova of T. solium and T. pisiformis may be disintegrated and activated directly into the artificial intestinal juice without the above pretreatment. Among the digestive enzymes applied in this experiment, trypsin was found most effective on the hatching. No hatching of the ova of H. nana and M. expansa was observed in the above artificial hatching-activating solutions. The fresh biles and bile salts were more effective on the hatching and activation of Taeniid ova than sodium taurocholate and sodium deoxycholate. It is turned out that the digestive enzymes or bile acids in the intermediate hosts may, not apparently be essential factor of determining the specificity of host-parasite relationships.
