The results of radiographic study of healing of fractured mandible are often inconsistent with clinical evaluation of bone healing pattern of it. In addition, there is inconsistency between radiographic studies. We think if such inconsistency is resolved, clinical assessment combined with radiologic evidence can be used to guide to more accurate clinical management. The purpose of this study is to evaluate radiological healing pattern of mandible, and to apply its result to clinical use. Panoramic view was used to analyze the change of radiographic finding in 35 patients (27 male, 8 female, ranging 17 to 53 years old) treated for mandibular fracture at the department of oral & maxillofacial surgery, SNUH in the period 1991 to 1998, Patients are all treated by rigid internal fixation using monocortical miniplate. Within 9 weeks, no change is observed at fracture site. Osteogenic change is observed at various time interval (3 to 21 weeks). We have found radiographic change of healing is observed 4 to 6 weeks later to clinical healing, According to this result, we recommend radiographic follow-up at 4 week, 10 week, 10 month.

In the head and neck area, there are so many sensory nerves, which are sometimes injuried iatrogenically or inadvertently so that involved patients complained of the loss of sensations. In such cases, it is important to judge the degree of injuries and regeneration of nerve for better diagnosis and treatment. Seddon and Sunderland's classification, which is commomly used, is focused on histological change and nerve conduction. As times goes by, it is difficult to access patient's sensory disturbance by this method. Until now, so many methods such as contract threshold, direction, two-point discrimination, pin prick, thermal discrimination and current perception threshold have been introduced for sensory evaluation. However, there hasn't been enough information regarding each methodology nor integrated standard methodology for the measurement. the purpose of this study is to get Korean adult normative sensory values of lower lip,chin and tongue using modified methods of contact thershold, ditection, two point discrimination, pin prick, thermal discrimination and assess degree of regeneration of sensory nerve damage.

This study was done in order to investigate the effects of performing the light exercise right after alcohol drinking on the changes of blood alcohol and ALT, AST concentration, All seven healthy collegiate students volunteered to two sections of experiment, Each subject drank one bottle of Soju(360ml, 75.6g ethanol) For forty minutes at the same speed of drinking with the same kind and volume of carbohydrate snacks. Each section of the study was conducted by a two-cross-over design with four days wash-out period, All volunteers performed brisk walking exercise corresponding to about 50-60%HRmax of exercise intensity For 30minutes immediately after alcohol drinking. Blood sampling was conducted by drawing about 10ml venous blood from antecubital vein at pre -alcohol drinking, and post- 1, 2, 4 hour alcohol drinking. Blood alcohol concentration reduced significantly at all time course in exercise group compared to Control group. However, the concentration of serum aspartate aminotransferase and alanine aminotransferase, the indicator of liver cell damage, showed no significant difference between two groups. In conclusion, performing light exercise such as brisk walking after alcohol drinking may somewhat help to reduce the concentration of blood alcohol Faster by influencing the alcohol metabolism.

We are able to generate the stable plasma in open air and nitrogen using a corona plasma treatment system(CPTS) with a high voltage. This was applied to treat the surface of rather non-polar HDPE(High Density Polyethylene) intended for the improvement of adhesion of over-coated layers such as coatings, printing inks. The surface tension of HDPE was significantly improved by the CPTS. The characteristics of surface layer were evaluated by means of contact angle measurement, ATR-FT/IR spectroscopy, and it was found that functional groups were introduced into the surface layer of the HDPE. The use of nitrogen was increased the surface tension of the HDPE from 33.8 mJ/m^2 to 66.56 mJ/m^2, and highly effective method of HDPE surface modification could be realized.

Until recent time many studies for relationship of dental abnormalities and cleft lip and palate were reported, higher prevalence of abnormality was revealed. The patients with large cleft size had significantly more missing teeth than patients with small cleft size. The tooth that is most usually missed in normal population is the mandibular second premolar, followed by the maxillary lateral incisor and the upper second premolar. The aim of this study was to analyse the prevalence of dental abnormalities and ectopic eruption in patients with cleft alveolus visiting our hospital. Radiographs, dental cast and records from about 60 patients were analysed to find the relation of missing, malformed, malpositioned tooth and delayed eruption and cleft site.

The electron-microscopic studies were undertaken to observe the morphological changes of Clonorchis sinensis obtained from experimentally infected rats treated with hexachlorophene, Hotol(1,4 bis-trichloromethybenzol), niclofolan and praziquantel which are known as highly active drugs against C. sinensis. For this study the rats were artificially infectedwith metacer-cariae isolated from Pseudorabora parva and were given a single oral dose of 50㎎/㎏ of hexachlorophene, 400㎎/㎏ of Hotol, 4㎎/㎏ of niclofolan and 600㎎/㎏ of praziquantel at 5 weeks infection. The Clonorchis worms were collected from the bile ducts of the rats which were autopsied at 24 hours after treatment with each drugs. With the collected worms, the fine structure was studied by means of scanning and transmission electron microscope. The findings of the observation were compared with those of each groups and untreated control groups. The results are as follows : 1. In the groups treated with praziquantel and hexachlorophene, the worms showed the elongation of oral-ventral suckers space, and the balloon shape structure was formed at anterior part of the worm. However in the groups treated with niclofolan and Hetol, the balloon shape structure was not formed. The lack of intestinal content was observed in the worms from the group treated with Hetol. 2. By the scanning electron microscopic observation, the bleb-like structures were observed on the sensory papillae around the two suckers of the worms from the group treated with praziquantel. In the worms from the group treated with niclofolan, the bleb-like structures were observed on the tegumental ridges near the ventral sucker, but the blebs were not formed on the sensory papillae. However, in the worms from the group treated with hexachlorophene, a few of blebs were found on the tegumental ridges. The worms from the group treated with Hetol were not observed any morphologicla changes by the scanning electron microscope, but in the most of worms many sperms appeared on the ventral sucker. 3. By the transmission electron microscopic observation in the tegumental syncytium, the mitochondrial degenerations were observed in the worms from the groups treated with niclofolan and hexachlorophene. In the worms from the group treated with praziquanted, the degeneration of mitochondriae in the tegumental syncytium, marked vacuolization in the tegumental basement, and the separation of basement membrane from the tegumental syncytium were also observed. 4. By the transmission electron microscopic observation in the intestinal lumen, the separation of intestinal and basement membrane was observed in the worms from the group treated with praziquantel, and the degeneration of the intestinal microvilli was observed in the worms from the groups treated with niclofolan, hexachlorophene and Hetol. Especially in the worms from the group treated with Hetol, marked degeneration of the intestinal microvilli and the "bubble" formation were also observed in the intestinal lumen.

평야지재배 적응 조생종 벼 품종의 선발 및 품종 육성의 기초 자료로 활용코자 극조생종(1품종)과 조생종(10품종) 및 준조생(3품종)등 총 14품종을 산간지(운봉)와 평야지(익산)에 지역별 표준재배법으로 공시한 결과, 1. 극조생종 및 조생종들은 감온성이 커 산간지에서 출수가 빠르나, 준조생종에 속하는 상미벼, 영덕34호, 히또메보레 등은 감광성이 감온성보다 커, 평야지재배에서 4일정도 빨리 출수하였다. 2. 수량성은 대부분의 품종들이 산간지재배에 비해 평야지 재배에서 높았고 대체로 출수가 빠른 품종일수록 지역간의 수량차가 크게 나타났으며, 출수가 다소 늦은 준조생종들은 산간지와 평야지의 재배에서 수량차가 크지 않아 산간지 뿐만 아니라 평야지에서도 적응성이 높았다. 3. 단백질함량은 숙기가 다소 늦은 품종일수록 낮은 경향을 보였고 산간지보다는 평야지에서 낮았으며, 품종간에는 오대벼, 운봉30호, 영덕34호, 신석조생, 상미벼 등이 함유량이 낮았다. 4. 식미치는 산간지재배가 평야지에 비해 보다 높게 나타났고, 출수가 늦을수록 높았으며, 지역간 차가 크게 나타난 품종은 극조생종인 키라라397이었고, 출수가 늦은 상미벼와 히또메보레는 차가 적었다. 5. 산온도와 수량과의 상관은 산간지에서만 영향이 있을 뿐 평야에서는 영향이 적고 일사량과 일조시수가 수량에 보다 상관성이 높았으며, 식미치는 적산온도와는 부의상관, 생육 일수와는 정상관을 보였다. This experiment was carried out to clarify the difference of rice yield and the quality of rice in southern plan area and in alpine area. Yield and quality of fourteen early varieties were investigated under the different transplanting dates and planting densities in southern plan area(Iksan) and in alpine area(Unbong). In the alpine area, extremely early variety and early varieties headed early compared to the plain area, but medium early varieties headed about 4 days late unlike the alpine area. The yield difference of most early varieties including Kilara 397 of extremely early flowering variety were greater in plain area than in alpine. The different of yield between plain and alpine area was less in varieties with Sinseogjosaeng, Odaebyeo, Akidagomachi, and Yeungdeuk34. The rate of protein was lower in plain area than alpine and more lately flowering than early, but palatability of milled rice was higher at the alpine area and more lately flowering varieties. Correlation coefficients between yield and meterological data during maturity, yield shower the significant correlation with integrated solar radiation and sunshine hours at cultured in southern plan area, but it showed only cumulative temperature in alpine area. Palatability of miller rice was positive correlation at growth duration but negative correlation at cumulative temperature.
