Tarsometatarsal fracture-dislocation is uncommon but severe lesion. Since this lesion is sometimes difficult to recognize by roentgenography, it is easily overlooked. Three patients were treated with open reduction and internal fixation with 3.5 mm cannulated screw and K-wire, two had treatment with open reduction and internal fixation with 3.5 mm cannulated screw only and two had treatment with dosed reduction and short leg cast only between January 1994 and May 1996. The duration of follow-up ranged from twelve to twenty-nine months after the diagnosis. Results were assessed by a subjective questiormaire, physical examination, and radiographic analysis. Multiple fixation techniques for maintaining the reduction of tarsometatarsl joint have been introduced. We recent]y used the 3.5 mm cannulated screw for internal fixation of the tarso-first and second metatarsal fracture-dislocation. We think cannulated screw fixation has several advantages; 1. The cannulated screw fixation is more rigid than the K-wire fixation. 2. There is an decreased risk of screw breakage with early weight bearing. 3. It is possible to compress the involved joints, if necessary. There were no disability in all patients. One patient who was treated with delayed open reduction and internal fixation with 3.5 mm cannulated screw and K-wire had a radiographic mild degenerative arthritis. And one patient who was treated with dosed reduction and short leg cast had a mild metatarsus adductus. But. these two patients were symptom free. There was no correlation between the severity of the diastasis and the patient s functional result.

Three Korean-bred strawberry cultivars 'Maehyang', 'Seolhyang', and 'Keumhyang', and a Japanese cultivar 'Tochiotome' were grown in a greenhouse and their physicochemical characteristics were investigated. Fruit weight of 'Seolhyang' and 'Keumhyang' in the first and second fruit clusters were greater than those of other cultivars and that of 'Tochiotome' was the greatest in the fifth fruit cluster. Fruit firmness generally decreased at later fruit clusters, and was the lowest in 'Seolhyang'. The sugars/organic acids ratios in the first and third fruit clusters of 'Maehyang' were 4.9 and 8.0, respectively, representing the highest values among all cultivars. The ascorbic acid content was the greatest in the second fruit cluster for 'Seolhyang', 'Keumhyang', and 'Tochiotome' cultivars and that of 'Maehyang' was the greatest at the third fruit cluster. The anthocyanin content was higher in later fruit clusters and was the highest in 'Keumhyang' overall. Results indicate that Korean cultivars bred for the plastic protected culture, which are intended for very early harvest, showed more desirable physical characteristics in the first and second fruit clusters, while the content of anthocyanin was greater in the fruits from later fruit clusters.

Medial patellar luxation in dogs is one of the most common patellar problems presented to the veterinary practitioner. It is observed in toy and miniature breed and the majority of cases is a congenital form. Because of extensor mechanism's instability, it causes deformity and disorder in the growth of the affected limb when the luxation is left without treatment As lameness is not easily detectable in puppies, early diagnosis and correction are essential for therapy. Up to now, there has not been any reports refering to the diagnostic methods and the optimal age for correction in young dogs. Thirteen 45-90 days old puppies, have grade I and/or II medial patellar luxation. Only by palpation, all 13 dogs were diagnosed of patelar luxation. Skyline radiographic view was useful to interpret patellar morphology and depth of trochlear groove only above 60 days old. However, it was difficult to make definite diagnosis patellar luxation. The caudocranial and lateral radiographic view as well as ultrasonographic skyline view were not showed of patellar luxation. 2 puppies had unilateral patellar luxation and 11 puppies had bilateral patellar luxation which more serious on the left than on the right. Only 3 puppies among 11 puppies with bilateral patellar luxation were observed of lameness degree 1. Regardless of grade of patellar luxation and lameness, we performed trochlear chondroplasty using a U-shape sculpture blade to minimize cartilage injury, transposition of tibia tuberosity with No. 1 Supramid to align extensor mechanism and lateral imbrication. After surgery, we examined the operated animal daily for 10 days and on 15, 30 and 60 days after surgery respectively. After operation, pain and fever became normal on 7 days, swelling on 10 days, respectively. On 10 days after surgery, dogs showed normal standing position, and normal walking was observed in 15 days after surgery. In force plate analysis, the operated legs were normal weight bearing at 30 days after operation. After surgery, not only patellar luxation and clinical signs have been gradually reduced but also bone growth have become normal without showing growth physeal plate injury. The survival rate of puppies over 62 days old was 100%, while 42-45 days old 37.5%. The above results suggest that optimal age for surgical correction of congenital medial patellar luxation is recommended over 60 days old. In conclusion, combination of trochlear chondroplasty, transposition of tibia tuberosity, and lateral retinacular imbrication is appropriate for over 60 days old puppies to efficiently correct patellar luxation.

재래종의 수집종 가운데서 선접된 다종다벽계통 (약칭 : MET)의 일반적 대성을 분석하여 청예용 옥수수의 육종을 위한 기초자료를 얻고져 수행한 시험결과를 요약하면 다음과 같다. 1. 주요 특성들의 환경변이와 유전변이를 추정하였던 바 MET계통의 분벽성, 개체당 이삭수(수수)는 환경변이보다도 유전변이가 큰 것으로 추정되었다. 개체당 건물중 및 건엽중 등도 유전변이가 커 MET 계통의 유전적 특성으로 확인되었다. 그러나 건기중, 입중 등은 환경변이가 컸었다. 2. 몇가지 특성의 평균치를 두 품종간에 비교하면 다음과 같다. 가. 분벽기수 및 이삭수 : 수원 19호는 환경변이 (파종기, 재식밀도)에 관계없이 분벽기이 없고 이삭수도 변하지 않았으나 MET계통은 분벽기수 및 이삭수가 크게 달라졌다. 나. 개체당 건물중, 건엽중 및 건기중 : 파종기나 재식밀도에 따라 다르기는 하지만 MET계통의 개체당 건물이 수원 19호보다 비교적 높았으며 건엽중은 월등히 높았고(1.5-2.5)배 개체당 건기중도 비교적 높았다. 다. 개체당 입중 및 입중 대 건기엽중비 : MET계통의 개체당 입중은 수원 19호보다 5～40% 낮았다. 따라서 MET계통의 입중 대 건기엽중비가 평균 35%였고 수원 19호는 41%로서 높았다. 3. MET계통은 파종 2주 후부터 분벽하기 시작하여 3 ～ 5일간격으로 다음 분벽이 되었으며 생육초기에 왕성하여 최고 6~7개에 이르나 2~3개만이 유효기으로 신장되였다. 유효기비율은 소식일수록 높았다. 분벽의 발생은 주기의 최하절읍부터 시작되는 데 하부절위가 짧아 한절위에서 분벽이 여러개 발생하는 것처럼 보였다. 제 1, 2분벽기의 기장은 주기의 것에 비하여 10cm 정도씩 짧았으며 재식밀도에 따라 주기 및 제일, 이분벽기의 기장은 소식(60$\times$60cm)한 경우 밀식(60$\times$20cm)한 경우와 같이 분벽들에 의한 밀식의 효과가 있었고 중간재식밀도(60$\times$40cm)인 경우에는 소ㆍ밀도의 중간되는 기장을 보였다. 4. MET계통은 개체당 이삭수가 많은 것에 반하여 이삭의 크기는 수원 19호의 \frac{1}{3}도 못되었다. 각분벽기에 달리는 이삭수는 소식의 경우 주기에 4개, 제일, 이분벽기에 2～3개씩 달렸다. MET계통의 입은 경입종이며 황색입이 주가되고 백색입이 약간 섞여 있었으며 100입중은 14~15gr. 의 소입종이었다. MET계통은 착수고가 수원 19호보다 훨씬 높았다. 5. 주요 특성간의 상간 : 수원 19호에 비하여 MET 계통은 주요 특성간에 높은 상관계수를 보여 유전상관도 높을 것이라는 것을 간접적으로 나타내주었다. 6. MET계통은 생장속도가 수원 19호보다 훨씬 늦었으며 개화기도 2~3주나 늦었다. 7. 흑조위축병 : 수원 19호와 같이 MET계통도 흑조위축병에 대해 이병성이었다. 이병성은 늦게 파종하거나 밀식할수록 높아지는 경향이 있었다.

The present investigation was focussed mainly on the development of the tumors and proliferating cells on the intestinal tracts of 1, 2-dimethyl-hydrazine(DMH)-treated young or adult rats. 26 rats(Wistar, 14 young rats weighting approximately 130~180gm and 12 adult rats weighting approximately 500~550gm) were given subcutaneously once weekly with 20mg of DMH/kg body weight(BW)/week for 8~22 weeks. Individual body weight were recorded weekly at the same day and time. The rats were killed at 8, 13, 15. 17, 19, 21 and 22 weeks. The intestinal tracts were opened longitudinally and carefully examined for tumors. The localization, number, and size of tumors were noted. Tumor-bearing areas were dissected out and fixed on neutral buffered 10% formalin and normal-looking mucosa from 8~22 weeks rats were also taken for fixation. Paraffin sections were stained by H-E for histopathological examination or with immunohistochemical stain for bromodeoxyuridine(Brdur) positive cells. 1. The growth proportion of body weight appeared to be decreased in the DMH-treated young rats than in control young rats and body weight of DMH-treated adult rats appeared to be 13.4% or less lower than weighted on 0 week. 2. Macroscopically, the developed tumors in the intestinal tracts were not observed as early as the 13 weeks after DMH treatment. The number of developed tumors per rat was found to be 14.3, 18.8, 22.3 in 15, 17 and 22 weeks. The numbers of tumors in intestinal regions per rat were 2.1, 4.3, 5.4, 2.5 in duodenum, jejunum, ilium and colon on 15 weeks, 2.3, 6.4, 7.8, 2.3, on 17 weeks, and 2.7, 9.3, 9.0, 1.3 on 22 weeks, respectively and the ileum and jejunum were higher in appearance rate of tumors and tumor types are dome shapes and diameter of largest tumor were 6.3mm. 3. Histopathologically, intestinal mucosa were thickened by the irregular distorted and distended crypts following hyperplasia. The tumors developed on the mucosa and submucosa and were recognized to be adenocarcinoma. 4. Immunohistochemically, the labeling index(LI) was calculated as the ratio of the number of Brdur-labeled cells to the total number of column cells of the crypts with longitudinal axis. LI of Brdur positive cells per crypt were 5.6%, 8.0% on small intestine of control and 22 week group, respectively and 3.7%, 12.7% on large intestine of control and 22 week group, respectively and were appeared to be increase in 22 week group than in control group and to be more number of proliferating cells in 22 week group than in control group. 5. LI of Brdur positive cells in 1, 2, 3, 4, 5 segments of crypt column were 11.7%, 10.7%, 3.8%, 0.6%, 0% in small intestine of control group and 23.5%, 11.8%, 2.3%, 2.4%, 0.8% in small intestine of 22 week group, and 5.4%, 7.4%, 3.8%, 1.0%, 0.4% in large intestine of control group and 29.5%, 20.3%, 5.9%, 6.3%, 1.3% in large intestine of 22 week group respectively. So results indicate that the number of proliferating cells by DMH treatment increase and were concentrated on the 1, 2 segments of crypt columns.

경골 과간 융기부의 견열 굴절은 비교적 드물지 않게 관찰되는 손상으로, 전위된 견열 골절편은 해부학적 정복과 견고한 고정을 필요로 한다. 그러나 관절경적 수술 방법을 포함한 대부분의 잘 알려진 수술 방법들은 비교적 복잡한 수술 기법과 정교한 수술 술기를 필요로 하며, 이에 따른 수술 시간의 지연과 수술 합병증으로 창상 감염, 조기 성장판 폐쇄 및 조기 관절 운동을 제한하는 고정력의 소실 등이 발생할 수 있다. 이에 저자들은 전외측 및 중앙부, 내측 mid-patella 입구를 사용한 관절경적 기법을 이용하여, 골편의 정복에 삽관 나사못을 사용함으로써, 비교적 짧은 수술 시간 안에 만족스런 정복과 고정을 얻을 수 있었으며, 술 후 조기에 능동적 관절 운동을 허용할 수 있었다. 또한 분쇄 골절의 경우 와셔를 사용함으로써 만족스런 고정을 얻을 수 있었다. 저자들의 방법은 수술 기법의 용이함과 금속 제거 시의 안전성, IV형 분쇄 골절에도 적용할 수 있는 점, 추가적인 피부 절개가 필요없다는 점, 성장기 소아에서 성장판의 손상 가능성을 줄일 수 있는 등의 장점이 있다고 사료된다.

Background: The purpose of this study is to examine the effect of resistance exercise on static and dynamic proprioception by applying elastic bands to the knee flexor, which can be performed earlier than proprioception, a weight bearing pattern. Proprioceptive training may be applied to the early period of recuperation training along with resistance exercise to prevent damage to the knees and the joints in the lower body, as well as the reoccurrence of injury, which is expected to improve the effect of static and dynamic proprioceptive training. Methods: The subjects of this study were 32 men and women in their 20s who volunteered to participate in the experiment which was carried out over the course of 6 weeks from March 14 to April 24 at K Hospital located in Yongin City. They were tested in two groups: the elastic band resistance exercise group (RE: Resistance Excercise Group, n＝17) and the joint motion range exercise group(ROM: Range of Motion Group, n＝15). In this experiment, static and dynamic proprioceptive tests were given to both groups before and after the test. In this study, SPSS Win ver.12.0 was utilized to perform a T-test on the independent samples in order to validate the identical features of subjects in the RE and ROM Group and substantiate the significance as to the difference between both groups before and after the test. Also, a paired T-test was conducted to compare the static and dynamic proprioception of both groups before and after the test. The statistical significance levels were ${\alpha}$＝.05. Results: 1.The static proprioception in both groups, RE and ROM, increased in a statistically significant way after the test(p<.05). 2.The static propriocetion of the RE group increased in a statistically significant way after the test(p<.05). However, the increase of the static proprioception in the ROM group was not statistically significant. 3.Static and dynamic proprioception of the RE group increased significantly more than that of the ROM group after the test(p<.05). Conclusion: The resistance exercise using elastic bands improved the static and dynamic proprioception more than the joint motion range exercise did, reducing the risk of injury by enhancing the location sense of the joints and the sense of motion and shortening the period of recovery from injury. The outcome of the experiment may provide basic data for developing an effective way to reduce the risk of injury among ordinary people and athletes.
