Dong-Eui-Bo-Kam is a medical book of Korean traditional medicine, which is of encyclopedic characteristics. Its contents imply almost every field of medicine. There are also descriptions of human parasites in this book under the title of 'Worms'. Worms described in the book are Sam-Shi-Choong, Ku-Choong(nine worms) the Oh-Jang-Choong(worms of five oragns). Among these Sam-Shi-Choong are not real worms, but quite mythological ones which have been mentioned in the religious Taoism. It is well-known that Dong-Eui-Bo-Kam has Taoistic characteristic. We can verify this characteristics by the fact that it mentions Sam-Shi-Choong on the top of the title 'Worms'. Dominant pathologic theory in the traditional medicine is a kind of balance theory, which defines the healthy state as the harmonious equilibrium of body elements. On the contrary parasitic diseases suppose real agents as the causes of diseases. This point of view appears to be quite different from traditional pathologic view.

In 1959, the Korean Society for Parasitology was founded by clinical scientists, specialists of public health, and 5 core parasitologists with experience in American science and medicine. The Society this year celebrates its 50th anniversary. Due to public health importance at the time of foundation, medical parasitology was the main stream for next 3 decades. Domestic problems of niche parasitic diseases, unlisted in 6 tropical diseases of major importance, had been studied by own efforts. To cope with the demand of parasite control, evaluation system for control activity was built up. Control activity against soil-transmitted nematodes, conducted for almost 3 decades, was evaluated as a success. Evaluation of praziquantel efficacy for clonorchiasis, paragonimiasis, and neurocysticercosis, population dynamics of Ascaris lumbricoides infection in a situation of continuous reinfections, diagnostic modalities of antibody tests combined with brain imaging developed for helminthiasis of the central nervous system and researches on intestinal trematodes were achievements in the first 30 years. During the recent 2 decades, science researches, such as cell and molecular biology of parasites and immunology of parasitic infections have been studied especially on parasitic allergens and proteolytic and anti-oxidant enzymes. Experiences of international cooperation for world health have been accumulated and would be expanded in the future.

This study was performed to review the transition of infection rate and major factor in decreasing pattern of intestinal parasites infection in Korea. The results of this review study are as follows: 1) The first study on the intenstinal parasites of Korean was performed by Muta(1913): he reported egg positive rate of A.lumbricodies 80%; that of T.trichiura 93%; that of Hookworm 65%. 2) After then the egg positive rates of A.lumbriciodes among Korean people has been higher thant 80% until and after Korean war. Owing to the biannual mass chemotherapy for 20 years be K.A.P.E.(Korea Association for Parasite Eradication), a decreasing pattern was recognized after 1960's. 3) The nationwide egg positive rate of A.lumbricodies was estimated by M.H.S.A.(Ministry of Health and Social Affairs) and K.A.P.E.(1971, 1976, 1981, 1986) to be 54.89%, 41.0%, 13.0%, 2.1%. 4) The causal agents in decreasing pattern of intestinal parasites in Korea are multifactorial such as mass chemotherapy, environmental sanitation, public education, improvement in socio-economic status, development in antihelminths, increase in use of chemical fertilizer, acceleration in national industrialization and so forth. 5) The infection rate of Korea is still higher than that of Japan and Taiwan but lower than any other countries in Southeast Asia. Nevertheless it is apparent that the present situation is not satisfactory and in this sense more effective and efficient control program is desirable.

This paper deals with cerebral paragonimiasis and cerebral hemispherectomy conducted as a treatment of cerebral paragonimiasis by Bo Sung Sim in Korea in 1950s-1960s. He demonstrated that cerebral hemispherectomy could be used for unilateral diffuse cerebral paragonimiasis. Sim learned cerebral hemispherectomy from Dr. L. A. French. at the University of Minnesota from 1955 to 1957 in America. The authors argues that Bo Sung Sim's introduction of cerebral hemispherectomy to Korea was not a simple application of an advanced medical technology, but a complicated and active process in that Sim used the technique to intervene intractable complications from cerebral paragonimiasis such as generalized convulsions, spastic hemiplegia and mental deterioration. Bo Sung Sim, one of the neurosurgeons of the first generation in Korea, was trained in neurology, neuropathology, neuroradiology and animal experiments as well as in neurosurgery at the University of Minnesota. After returning to Korea, Sim faced parasitic diseases, one of the most serious public health problems at that time, which were far different from what he learned in America. As a neurosurgeon, Sim tackled with parasitic diseases of the central nervous system with various diagnostics and therapeutics. In 1950s, more than one million populations suffered from pulmonary paragonimiasis acquired by eating raw crabs or by feeding juice of crushed crayfish for the treatment of measles in Korea. About 26.6 percent of people with paragonimiasis had cerebral paragonimiasis. Before bithionol therapy was introduced in 1962, neurosurgery was the only available treatment to control increased intracranial pressures, intractable epilepsy, paralysis and mental deterioration. Between 1958 to 1962, Bo Sung Sim operated on 24 patients of cerebral paragonimiasis. In two of them, he performed cerebral hemispherectomy to control intractable convulsions when he found diffuse cerebral paragonimiasis and cerebral atrophy at the operating table. The two patients were recovered dramatically after the operation. The first patient became a part of medical campus for 20 years after hemispherectomy, doing chores at the hospital and helping Bo Sung Sim for his teaching neuroanatomy. The presence of the hemispherectomized patient in the classroom impressed the students deeply. Furthermore, the hemispherectomized patient stimulated Sim and his school to perform research upon the neuroanatomy and neurophysiology of the brain with hemispherectomized animals.
