Behind a wall of mordern sanitation, it's believed that the parasitic diseases became very rare in Japan. But in spite of decreasing the parasitismus of Nematodes, the patients harbouring cestodes became to increase.This paper described the clinical picture of the human taeniasis (Taenia saginata), the roentgenographic signs produced by taenia saginata and an investigation of the host- parasitic relationships. In Okayama District, recent yearly rate of cattle, containing viable cystocercus bovis was 0.1 to 0.2%. Since 1955 to. 1971 in Chugoku District of Japan, 50 patients with Taenia saginata aged 3 to 70 years were studied. Most infections were asymptomatic (48%) and 52% of the patients were symptomatic. The symptomatic patients complain the abdominal pain (16%), anal discomfort and itching (10%), decreased appetit (8%) and malaise (8%) (Table 5).In the patients within the 4 months after infection of the beef tapeworm, over 10% eosinophilia were found in the peripheral blood. But in the patients, over 5 months after infection of the beef tapeworm, the authors could not be recognized the eosinophilia of the peripheral blood. (Fig. 1)Since X-ray demonstration of the scolex of Taenia saginata was rare, the authors demonstrated the scolex and the neck portion of tapeworm on roentgenograms in the 3 to 5cm anal side of the duodenojejunal angle, correctly (Fig. 3).In all cases, the adult proglottide of the tapeworm could be visualized clearly on contrast roentgenograms of the small bowel and appears as a long, taperring radiolucency (Fig. 2, 5.).
