4.A Study on Status of Death in Rural Residents.
Korean Journal of Preventive Medicine 1977;10(1):155-159
A study on the status of death in rural area was conducted during the period from July '75 to August '75. 1,225 families and 8,067 population (4,124 male, 3,943 female) had been lived and 149 events of death since 5 years before study were occurred in survey area, Nammyon, Hwasoongun, chonnam, The summarized results were as follows : 1. Quinquennial death rate was 3.7 (5.2 for male, 2.1 for female). 2. In respect of age group, the highest group was over 70 years old group (age at death, 30.8% of total death). High age groups (over 50 years old) occupied 71.1% of total death and death rate in these groups were higher in male than female. Child death (0-4 years old) occupied 7.4% of total death and infant death rate was higher in female than male. 3. Duration of sickness before die was highest in 1 to 12 months (39.6%). 4. The most frequent cause of death was disease of digestive system (12.1%). Other important causes were disease of circulatory system (10.7%), disease of respiratory system (9.4%) and infectious and parasitic disease (4.7%). Diseases of digestive system was not the most frequent cause of death in male (14.0%) and disease of respiratory system was the most frequent cause in female (9.5%).

Korean Journal of Anatomy 1997;30(2):199-204
The partial splenectomy was performed on the basis of the arterial distribution in order to reduce complications. The spleen consists of the various histologic components that have different functions. But we can not find the reports whether the distribution of red pulp, white pulp and trabecula is uniform or not according to the regions of the spleen. We used 15 spleens from Korean[male 8, female 7 and age 17-74]. The volume was measured with the mass cylinder. The 1cm3 blocks were selected in 5 different regions. Whole splenic slices by celloidin embedding were made from two spleens. The point counting method with eyepeice reticule was used for the measurement of the distribution of red pulp, white pulp and trabecula. The results were as follows : 1. The volume of the spleen was ranged 45-158ml and the individual difference was marked. The male spleen was larger than female`s [p<0.05]. 2. The ratio of red pulp, white pulp and trabecula of the paraffin embedding preparations was 83.2, 10.9, and 5.9% respectively. There was no significant difference in the distribution of the histologic components among five regions[upper, hilum, middle, outer, and lower]. 3. The distribution of red and white pulps in whole splenic slices was not uniformity. The ratio of red pulp, white pulp and trabecula in whole splenic slices was 80.1, 13.4 and 6.5% respectively. These results showed no significant difference with those of five regions of the spleen.

9.Clonorchis sinensis in Kyungpook Province, Korea 1. Distribution and demonstration of the cercaria of Clonorchis sinensis from snail, Parafossarulus manchouricus Bourgigant.

Studies were conducted in rivers in Kyungpook Province, Korea from July 1970 to September 1974 to determine the stations where Parafossarulus manchouricus, the intermediate snail host of Clonorchis sinensis, are abundant, and the infection rates of these snails with the cercaria of Clonorchis sinensis. Snail collections were made during four consecutive summers(July to September in each year). Ten snail habitats were found. The population density of the snails per square meter of the river bottom ranged from 25 to 250. The highest population of snails was encountered at the Dong-chon station. Cercaria studies by means of the immersing and crushing technics indicated surprisingly low rate of Clonorchis sinensis infection among the snails examined. The proportion of infected snails in Kyungpook Province was 0.8 per thousand of all snails examined. Results indicated that the Parafossarulus manchouricus exists in limited areas within the rivers under study and the infection of the snail with the cercaria of Clonorchis sinensis is very low.

10.ULTRASTRUCTURAL INVESTIGATIONS OF THE INTERFACE BETWEEN CULTURED PERIODONTAL LIGAMENT CELLS AND TITANIUM.
Journal of the Korean Association of Oral and Maxillofacial Surgeons 1997;23(4):668-672
A particular problem associated with osseointegrated implants is the fact that the implants lack a periodontal ligament. Thereby, marginal inflammation around an implant may cause more serious bone loss than does marginal inflammation around teeth with a periodontal ligament. In addition, osseointegrated implants are ankylosed and do not haute the same mobility as natural teeth with a periodontal ligament. Implants with a periodontal ligament would eliminate these problems. In order to explore the possibility of producing a periodontal ligament around titanium dental implants, a study of the attachment of cultured periodontal ligament cells to titanium was carried out. Periodontal ligament cells obtained from premolar teeth of individuals undergoing tooth extraction for orthodontic reasons were cultured on titanium-coated epon blocks. Sections of the blocks were cut perpendicular to the surface of the cell layer. Transmission electron microscopy of the periodntal ligament cells/titanium interface showed that there was no evidence of attachment at the cultured periodontal ligament cells titanium interface. The microfilaments, commonly located adjacent to the titanium surface, run mostly parallel to the titanium surface. The study showed that cultured periodontal ligament cells did not create an attachment structure on a titanium surface similar to that of natural teeth.
