The clinical manifestations in filarial infection were examined during 1965-1966 from the known endemic areas: Yongju, a mountainous inland area and Cheju-Do, an island.
All the microfilaria which were found during the survey were Brugia malayi. The principal symptom was cuticular hypertrophy (elephantiasis). It was found in 4 cases from Yongju among 707 villagers, 84 cases from Cheju-Do among 2,376 villagers. Four microfilaremia cases (4.5%) were found among a total of 88 cases of elephantiasis. In Cheju-Do, the higher incidence of elephantiasis was observed among people over 20 years old and the females showed much higher incidence than males (30 males and 54 females). The cuticular hypertrophic changes (elephantiasis) appeared more often in the lower extremities(77%) than in the upper part of the body, and in the right side than in the left.

By an application of Sigma-Frankel methods, two transaminase systems, glutamic-pyruvic transaminase and glutamic-oxaloacetic transaminase, were found to operate at a mesurable rate in 2 species of nematodes(Ascaris lumbricoides and Ascaridia galli), 5 species of trematodes (Clonorchis sinensis, Fasciola hepatica, Eurytrema pancreaticum, Paramphistomum cervi and Paragonimus westermani) and 5 kinds of cestodes (Diphyllobothrium mansoni, Dipylidium caninum, Taenia pisiformis, Cysticercus cellulosae and Cysticercus pisiformis). A comparison was made of the transamination reactions in nematodes and those of trematodes and cestodes. And the significance of transaminase in these parasites is discussed in relation to protein synthesis and its utilization.

Radioactive C(14)-glycine was given to Clonorchis sinensis in Tyrode medium in order to trace the metabolic fate of the labeled carbon. The labeled carbon from glycine enters into every major fraction of Clonorchis sinensis and is highest in the fraction of protein and nucleic acid. Significant amount of C(14)-glycine is incorporated into respiratory carbon dioxide. Relatively high percentage of C(14)-glycine in medium is converted to amino acid fraction and lipid fraction of the worm. In general, glycine is continuously being utilized in the synthesis of proteins and for energy production despite the uptake rate of glycine decreased gradually as incubation proceeds.

No significant difference was noted in canine hookworm infection due to hormone influence between the control group and the gonadectomized rats which were sacrificed 17 days after gonadectomy and 7 days after the infection. However in the rats which were infected 20 days after oophorectomy a significant difference was thought to be present in this group(176 +- 12.9 larvae/rat) compared with the control group (138 +- 21.2 larvae/rat). On the other hand, in the castrated group the number of larvae (138 +- 37.1 larvae/rat) was less than that in the control group (208 +- 43.4 larvae/rat). In the estrogen-injected male and female groups, there were no difference compared to the control, but the testosterone-injected groups of males and females showed more susceptibility to infection by A. caninum than in the control group. The Capillaria hepatica infection to the castracted host showed no significant difference between the gonadectomized and the control group. (oophorectomy; 214 +- 28.0), castration; 250 +- 36.5 and control; 191 +- 58.2 and 270 +- 30.1 adults/rat). Concerning the influence of the host's sex hormone on egg production of canine hookworm, there was a significantly decreased egg production in castrated dogs(6,578 +- 664.0 egg per gram) compared to the control dogs(9,711 +- 1,322.3 egg per gram). The same results were observed in vitro test. In the host, the susceptibility to hookworm infection was reduced in castrated rats, while oophorectomy group had a little or no effect. In the favorable or unfavorable hosts, testosterone gave the tendency of increasing susceptibility of the host to infection, while estrogen did a little or no effect.
The Parasitological investigation on the encysted metacercariae in brackish water fish, Tribolodon taczanowskii, in the downstream of Hyungsan river which is located in Kyungpook Province of Korea, were carried out serially and the following results were obtained.
Metacercariae of Pseudexorchis major were found in six fishes(15.8 per cent ) out of 38 examined. Parasitic frequencies of the encysted metacercaria of Psedexorchis major in Tribolodon taczanowskii were 15.8 per cent (6 out of 38) in the scale, 10.5 per cent (4 out of 38) in the fin, 13.2 per cent (5 out of 38) in the gill, 10.5 per cent (4 out of 38) in the oral cavity and 7.9 per cent (3 out of 38) in the flesh. The worms were identified as Pseudexorchis major (Hasegawa, 1935) Yamaguti, 1938 by morphological studies on the metacercariae, excysted metacercariae, adults and eggs, and compared with prereported Pseudexorchis species.

There has been no report on human infection of Hymenolepis diminuta in Korea until the first 3 cases were reported by our members after the identification of those eggs in stool in 1964. However, the distinct differentiation between H.
diminuta and H. nana would often be difficult by the shape of eggs without adult worm. In 1965, authors found the additional case revealed the eggs in stool and succeeded to obtain three adult worms of H. diminuta from 10 years old boy in Pusan. The characteristic morphology of egg and adult worm were discussed to compare to those of H. nana.
Conclusively, the first human infection of H. diminuta in Korea was reported after the identification both the eggs and adults worms
