Abstract PDF: The present status of control treasures for public health important helminthic infections in Korea was surveyed in 1969 and the following results were obtained The activities of parasitic examination and Acaris treatment for the positives which were done during 1966 to 1969 were brought in poor result and could not decrease the infection rate. It is needed to improve or strengthen the activities. The mass treatment activities for paragonimiasis and clonorchiasis in the areas which were designated by the Ministry of Health were carried out during 1965 to 1968 with no good results in decrease of estimated number of the patients. There were too many pharmaceutical companies where many kinds of anthelmintics were produced. It may be better to reduce the number of anthelmintics produced and control the quality. The human feces, the most important source of helminthic infection, was generally not treated in sanitary ways because of the poor sewerage system and no sewage treatment plant in urban areas and insanitary latrines in rural areas. The field soils of 170 specimens were collected from 34 areas out of 55 urban and tourist areas where night soil has been prohibited by a regulation to be used as a fertilizer, and examined for parasites contamination with the result of Ascaris egg detection in 44%. Some kinds of vegetables of 64 specimens each from the supply agents of parasite free vegetables and general markets were collected and examined for parasites contamination with the results of Ascaris egg detection in 25% and 36% respectively. The parasite control activities and the ability of parasitological examination techniques in the health centers of the country were not satisfactory. The budget of the Ministry of Health for the parasite control was very poor. The actual expenditure needed for cellophane thick smear technique was 8 Won per a specimen. As a principle the control of helminthic infections might be led toward breaking the chain of events in the life cycle of the prasites and eliminating environmental and host factors concerned with the infections, and the following methods may be pointed out. 1) Mass treatment might be done to eliminate human reservoirs of an infection. 2) Animal reservoirs which are related with human infections might be eliminated. 3) The excretes of reservoirs, particularly human feces, should be treated in sanitary ways by the means of sanitary sewerage system and sewage treatment plant in urban areas and sanitary latrines such as waterborne latrine, aqua privy and pit latrine in rural areas. The increase of national economical development and prohibition of the habit of using night soil as a Fertilizer might be very important factors to achieve the purpose. 4) The control of vehicles and intermediate hosts might be done by the means of prohibition of soil contamination with parasites, food sanitation, insect control and snail control. 5) The improvement of insanitary attitudes and bad habit which are related with parasitic infections might be done by the means of prohibition of habit of using night soils as a fertilizer, and improving eating habits and personal hygiene. 6) Chemoprohylactic measure and vaccination may be effective to prevent the infections or the development of a parasite to adult in the bodies were invaded by parasites. Further studies and development of this kind of measures are needed.; Summary

Abstract PDF: By using Siregnost FD 91 body plethysmograph. we measured thoracic gas volume (TGVe) at end of expiration in 19 healthy subjects aged 20-43 years in order to compare with functional residual capacity (FRC) measured by closed circuit method. The results obtained were as follows: 1. Mean values of TGVe and FRC were 3.395+/-0.585 liter, and 3.398+/-0.618 liter, respectively. 2. A advantage of the body physthysmographic method for measuring thoracic gas volume was that it were rapid, safe. and easy to perform, requires no gas sample for chemical analysis, and measured TGVe several times.; Summary

Abstract PDF: The authors compared the basic characteristics of rural woman in relation to family planning for June 1967 and June 1969 in Kyung San Country Kyungpook Province, Korea. The statistics showed that these characteristics are gradually changing. The marriage age was slightly higher than the past year and the formal education of women increased. The ideal children number, and tile gravidity and mortality rates decreased. At the same time the number of induced abortions, the knowledge of family planning, and the acceptance rate of contraception increased. These phenomena seem to follow the present worldwide trend.; Summary

Abstract PDF: An epidemiological survey on cholera was made toward the 291 cases admitted in Pusan National University Hospital. The results were as follows. 1. The most predominant age groups among all cholera patients were form 30 to 39(21.3%). 2. 74.9% of all cases got under the educational background of primary school and 69.4% of all cases occurred at the low income group. 3. Daily average numbers of patient were 6.2 and maximum numbers were 15, August 19, 1970. 4. Among the food eaten prior to onset, drinking water was the most predominant with 16.2% and next, food and noodle groups were 14.8% and 10.3% respectively. 5. Regarding incubation period, it was found that "within 48 hours" was 83 5%. 6. Patients occurred mainly in Suh Ku area with 105(36.1%) of all closes. 7. Carrie rates among family members were 1.78%. 8. Carrier rates among residents of epidemic area were 0.l2%.; Summary

Abstract PDF: Laboratory susceptibility tests with various insecticides against houseflies(Musca domestica L.) were simultaneously conducted with larvae. As a result of these experment the following conclusion has been obtained. 1. The relalive ratio to various insecticidal effects were naled > DDVP > diazinon > gamma-BHC > malathion > dieldrin > DDT in houseflies larvae. 2. It was noted that resistance to various insecticides is larvae was in proportion to resistance in adults.; Summary

Abstract PDF: Alteration of H-and M-isozymfs of Lactic Dehydrogenase(LDH) were observed in the various tissues after exposing the rats to 50ppm and 250ppm of sulfur dioxide. These isozymes of the respective tissue were separated by Diethlaminoethyl(DEAE)-cellulose from tile tissue homogenates of brain, lung and muscle, presenting the activities by rate of reduction of nicot inamids-adenine-dinucleotide (NAD+). Pure LDH and the coenzyme NAD (NAD) were directly treated with sulfur dioxide in vitro order to find out the direct to sulfur dioxide on LDH and NAD+ and the results were as follow. 1. In the normal tissues, the H-isozyme activity was dominant in the brain and heart, and tole M-isozyme in the muscle. 2. In the lung tissue of normal rats, there was no different between tole activity of H-and M-type of LDH. 3 When rats inhale sulfur dioxide gas in concentration of 50ppm and 230ppm, it appeared that the H-type tend to be suppressed in aerobic tissues and the M-type in anaerobic tissues. 4. In the lung tissue exposed to sulfur dioxide, both the LDH activities were suppressed. 5. It seems that LDH and the coenzyme (NAD ) are not directly affected by exposing in sulfur dioxide gas.; Summary
