A study on the morbidity of syphilils among 729 workers on Po Hang and Ul San Industrial Complexes at the routine periodical examination was performed. In addition to the morbidity, factors related to the disease infection such as educational level, religion, preventive measures taken by the workers, history of urethritis, and so on were studied and analysed to check significant relation. The result were as follows. 1. VDRL and RPR tests were undertaken to determine the sensitivity and specificity of RPR tests which was utilized for all the workers studied. It related 86.4% of sensitivity and specificity 87.7% of specificity from the RPR tests, and 81.8% of sensitivity and 90.1% of specificity from the VDRL tests compared with RPCF test. There were 87.4% of agreement rate vetween RPR and VDRL. Actually, RPR was more sentitive but less specific than VDRL , and found to be a satisfactory screening test for syphilis especially in the fields. 2. Among the workers in Po Hang Area 24.0% of them revealed reactive result, and in Ul San Area 5.2% revealed result showing 4.6 times of risk among workers on Po Hang Area. 3. There were no statistically significant differences between RPR reactive rates and personal characteristics such as educational level, region, history of urethritis experience, history of coitus with prostitute, and preventive measures of V.D taken by workers of evaluated by area of Po Hang and Ul San separately. 4. V.D. could be encountered as an occupational disease in certain conditions of working places and the psychosocial problems of workers. And so, It is necessary that the workers working in special estates such as on Po Hang Industrial Complex should be checked to be screened out by RPR test at periodical examination also should include RPR test be compared with. Regardless of the workmen's compensation, establishment of V.D. treatment clinic of system for such industrial workers is urgently needed. Health education regarding V.D. is another subject to be performed.

This survey attempted to determine the overall health situation in Kyunggido in terms of sickness prevalence, sickness distribution, demand for medical care by type, and utilization of medical care. The survey was conducted on 766 households, or 4,065 people, from July 1-31, 1975. The findings from the survey are as follows: 1) In terms of age distribution, 28.7% of the sample was from 10-19, the 40-49 age group was the next largest group, and those over 60 made up 7% of the sample. 2) The education distribution is as follows, 30.4% completed primary school, 22.4% had no formal education, 20.6% attended but did not onplete primary school, and 1.8% attended universities or higher. 3) In terms of occupation, 55.9% were unemployed or family employees, which represents a large dependent population, 30.4% of the workers were employed in farming or fisheries. 4) The marital status is as follows, 58.3% of the women were married, 32.3% unmarried, and 7.5% divorced. 5) The prevalence rate of monthly illness was 19.7% of 100 infant, 42.8% became fatally ill within the first year of life. This is a very high percentage compared with more developed nations. 6) Of those reportion on illness, 54.6% sought treatment. The rate of treatment was highest in infants at 77.7%. Us age increased, demand for treatment decreased to 43.1% for those in the oldest age group. The oldest age group also had the highest rate of non treatment at 56.8%. 7) The demand for medical care showed that 65.6% utilized drug stores, 20.2% utilized hospitals and clinics, 5.4% used herbdrug-stores and herb clinics, and 3.9% relied upon folk medicine and witch craft. 8) The utilization of medical facilities by sex is as follows, 65.1% of the men and 66.0% of the women used drug stores, and 19.2% of the men and 20.2% of the women used hospitals and clinics. However, more men (3.5%) were hospitalized than women (1.8%). 9) In terms of out-patient care, the largest age group of males was 10-19 (28.2%), and the largest age group of females was 0-9 (30.8%). There was no sex difference in the use of western pharmacies. Men age 30-39 and women age 50-59 were the most frequent users of herb clinics. 10) The rate of receiving treatment at drugstore hospitals went towards declining level in the second case of what while increasing much more at herb clinics and folk medicines in the second case than the first one. 11) After primary utilization of hospitals, 32.7% of the adults aged 20-59 used drug-stores as a secondary source of care, and 12.8% of children and youth under age 20 continued receiving care at hospitals. 12) After primary utilization of drug-stores, 32.5% of the adults continued to seek care at drug stores and 1.8% used hospitals. 4.2% of those over age 60 utilized folk medicine and witch craft.

The results of the tests carried out in 1971 strongly suggested that a considerable portion of the flea population in MR 2 had developed resistance not only against DDT but also malathion and dieldrin. There is also the possibility of the fleas developing a resistance to diazinon and lindane. Thus careful consideration should be given to the continuous use of diazinon. In areas where fleas had developed a resistance to malathion, further tests should be conducted continuously to confirm the possible development of resistance. Other insecticides which have not been used in Vietnam for any purpose should be ready to be substituted, if the development of resistance is confirmed.

In 1933 Shope described an infectious papilloma of wild cattontail rabbits. Shope rabbit papilloma is a virus-induced epidermal neopIasm indigenous to western cottontail rabbits and readily transmissible to domestic rabbits by inocuiation with an cell-free extract of wild cottontail papilloma. Shope papilloma induced in the domestic rabbits may spoataneously, remain benign, or progress to carcinoma. Kidd et al. (1936) noted that the regression is not correlated with the titer of virus neutralizing antibody. The possibility that papilloma regression is brought about by a mechanism anaIogous to that operating in allograft rejection was suggested by kidd et al. (1938) with the view of the histological resemblance between papilloma regression and rejection of allografted tissue. That regression is mediated by an immune mechanism is strongly indicated by the findings of Evans et al.(1962) that the proportion of rabbits showing regression is substantially increased by vaccination of rabbits with their own papilloma tissue or with papilloma tissue from another rabbits. McMichael (1967) demonstrated that suppression of regression was achieved by use of large doses of corticosteroid. The effect of 5-fluorouracil on human warts was mentioned as being effective by Goldman et al. (1963). In Korea resinous extract from Paulownia coreana has long been used empirically in the treatment of human warts. In this investigation effects of dexamethasone administration on the development and the spontaneous regression of Shope papillomas in domestic rabbits were studied. At the same time, observations were made to evaluate the comparative effectiveness of topical application of 5% 5-fluorouracil ointment and resinous extract from Paulownia coreana on Shope papilloma in the domestic rabbit. The results are summarized as follows: l. Administration of dexamethasone significantly reduced the spontaneous regression of Shope papillomas in domestic rabbits by 12 weeks after virus inoculation. 2. Topical application of 5% 5-fluorouracil ointment on Shope papillomas cured the tumors by 4 weeks of drug application. However, similar treament with resinous extract from Paulownia coreana was without any demonstrable effects. 3. Marked losses of body weights became manifest in dexamethasone treated rabbits. 4. Reinoculation of Shope papilloma virus into 2 rabbits whose papillomas had regressed 3 months ago failed to produce papillomas.
