For seven years from 1962 to 1968, fecal specimens of the patients were examined not only for the discovery of intestinal protozoa and helminths, but also to provie data on the incidence of intestinal parasites among the residents of Kyungpook Province, Korea. The Formalin-ether sedimentation, Lugol solution, and Heidenhain's iron-hematoxylin stained films were prepared for the recovery of intestinal parasites. Of 2,414 samples of feces examined, 35.7 percent were found to be infected with one or more species of protozoa. Among six species of protozoa detected, Entamoeba coli was observed most frequently(15.3%) followed by Entamoeba histolytica (11.9%), and then the Enteromonas hominis least often(1 case). For the survey of helminth, of a total of 5,288 fecal specimens examined, 86.7 percent were positive for one or more species of helminths.
Trichocephalus trichiurus revealed the highest infection rate (83.6%), while Trichostrongylus orientalis was next (61.6%), and Ascaris lumbricoides was unexpectedly low(40.9%). The incidence for hookworm and Clonorchis sinensis was 22.4 percent and 29.8 percent respectively.
Triple infections were found more frequently than double infections, and mixed infections of six or more species of helminths were observed in 3.8 percent of specimens.

The authors made a study on the species and distribution of helminths in Korean native cattle. The feces and internal organs from 1,755 heads were examined in slaughter plants of Taejon district. The results are summarized as follows.
Distribution and infestation rate of helminths among the collected samples are, Paramphistomum spp. 68.4 per cent, Fasciola spp. 48 per cent, Eurytrema spp. 23.5 per cent, Moniezia spp. 8 per cent, Dictyocaulus spp. 3.5 per cent, Trichostrongylus spp. 12.4 per cent, and other species 26.8 per cent, respectively. In 33.4 per cent of ths cases, single infestation was seen and in 31.5 per cent, 18.0 per cent, and 14.0 per cnet mixed infestation of double, triple, and quadruple or more species were seen, respectively.
Geographical analysis of infested helminths in the native cattle indicates: Among the trematoda order, Paramphistomum spp. and Fasciola spp. showed high rate of infestation throughout all districts of the country, especially Cheju island with a significant higher rate. Central district (Taejon) was higher in number of native cattle infested with Fasciola spp. than any other district of the country investigated. The rate of infestation with cestoda also showed to be higher in Cheju island than any other district of main land, but the rate of infestation with other nematoda showed no geographical difference.

A 25 years old sergeant of Dicrocoeliidae infection was studied. This patient was not a spurious infection case and diagnosis was based on rocovery of the characteristic eggs consistently in the feces for 2 month. This case had no history of ingestion of ingestion of ants, land snail of grasshopper. In this case with complaints of flatulence, nausea, loss of appetite and dizziness, physical examination reveald no pathological findings except pale cornea. Liver function tests were observed to be normal and there was slight eosinophilia.

The importance of Toxoplasma gondii in human disease stimulated a number of electron microscope studies on the structure of this protozoan parasite. Gustafson et al. first studied the fine structure by means of thin sections in 1954. Many other papers havs subsequantly appeared. It is well known that Toxoplasma gondii has two stages in its life cycle-the proliferative forms and the cyst. The purpose of the electron microscopical work reported here was to study the fine structure of Toxoplasma gondii with recent techniques clarifying the correlation between the proliferative forms and cyst. RH strain and KM strain as proliferative forms on the one hand and Beverley strain as a cyst form of Toxoplasma gondii on the other hand were used throughout this study. The conoid, toxoneme, nucleus, nucleolus, osmiophilic granules, mitochondria and vacuoles were found in RH strain as wsll as in KM strain and Beverley strain. The endoplasmic reticulum was found in the cytoplasm of RH strain and KM strain. It was better developed in KM strain than in RH strain. The outside contour of the organism of Beverley strain was somewhat irregular and toxoneme of this organism was better developed than in the other two strains. Vacuoles were found in RH strain, KM strain and Beverley strain. Furthermore, tube-like bodies were observed in the vacuoles of the organism of RH strain.
In KM strain, two organisms of the same size were demonstrated in the leucocytes. It was presumed that they were products of longitudinal division.
