Background: Peripheral nerve injury sometimes leads to chronic neuropathic pain such as causalgia. A subset of patients with causalgia have a sympathetically maintained pain which is often evoked by cooling stimuli. However, our knowledge on adrenergic receptor types responsible for cold-evoked pain that is sympathetically dependent is lacking. The present study was conducted to investigate subtypes of adrenoceptors involved in mediating cold-evoked pain that developed following peripheral nerve injury. Methods: Neuropathic surgery was performed by a unilateral ligation of L5 and L6 spinal nerves of rats. Behavioral sign of cold-evoked pain was examined for 5 min by measuring cumulative duration of time that the rat lifted its foot off a metal plate held at cold temperature ($5^{\circ}C$). Whether cold-evoked pain behavior was affected by antagonists of various subtypes of adrenoceptors, which were administered intraperitoneally before and after the ligation, was investigated. Results: After ligation, duration of foot lifting on the ligated side at cold temperature increased as compared to the pre-operative period. This increase maintained for the entire 40-day test period. Pretreatment with alpha-antagonist phentolamine produced a suppression of cold-evoked pain behavior that was not affected by beta-antagonist propranolol pretreatment. Prazosin, alpha-1 antagonist, suppressed cold- evoked pain behavior when treated either before or after nerve ligation. On the other hand, alpha-2 antagonist yohimbine was without effect on cold-evoked pain behavior whether it was treated before or after the ligation. Conclusions: The results suggest that peripheral nerve injury develops cold-evoked pain that is sympathetically dependent, and that alpha-1 adrenoreceptor plays a critical role for the generation of this type of pain in its initiation as well as maintenance.

Purpose: We evaluated the results of various surgical treatments for hallux valgus with and without attempting to correct sesamoid subluxation. Materials and Methods: Thirty-one cases in 26 patients were involved in this study: Group I (15 cases) - surgery performed only to correct the hallux valgus angle (HVA) and the first-second intermetatarsal angle (IMA) in AP view; Group II (16 cases) - surgery performed to correct HVA and IMA and also to reduce the subluxation of sesamoid. The degree of sesamoid subluxation was measured from a pre- and intraoperative sesamoid tangential views. For both groups, we analysed the status of the sesamoid in pre- and postoperative radiographs and performed clinical evaluation using the Mayo clinic forefoot scoring system. Results: The average amount of correction during postoperative period and loss of correction at last follow-up in the sesamoid tangential view were as follows: soft tissue procedures (5 cases) - group I: grade $1.0{\pm}0.4/1.5{\pm}0.3$ and group II: grade $2.0{\pm}0.9/0.5{\pm}0.08$; chevron osteotomy (12 cases) - group I: grade $1.0{\pm}0.5/1.2{\pm}0.3$ and group II: grade $2.2{\pm}0.7/0.9{\pm}0.2$; proximal metatarsal osteotomy (14 cases) - group I: grade $4.0{\pm}0.4/1{\pm}0.2$ and group II: grade $4.7{\pm}1.1/0.8{\pm}0.1$. In clinical evaluation, more than 93% of the feet had a good result in both groups. The analysis of these data for each treatment type did not show any statistically significant differences between groups I and II. Conclusion: The radiologic and clinical results did not validate our attempts to reduce the sesamoid during surgery.

Purpose: To evaluate the results of MIPPO (minimal invasive percutaneous plate osteosynthesis) technique for distal tibial metaphyseal fractures. Materials and Methods: It is a retrospective study of 13 patients who were treated by MIPPO technique for distal tibial metaphyseal fractures from Jan. 2001 to Jan. 2003. The average age was 46.7 years and mean follow-up period was 13.3 months. According to AO classification, there were 8 cases of A1, 3 cases of A2, 1 case of B1 and 1 case of C2. One case of A1 was a Gustilo-Anderson type I open fracture and fibular fractures were combined in 12 cases. We applied anatomical reduction and internal fixation for the fibular fractures and internal fixation on the medial side of the tibia by MIPPO technique for distal tibial metaphyseal fractures. Clinical results were evaluated using radiographic results, Neer score, the starting time of postoperative exercise and clinical complications. Results: According to the Neer score, all cases showed satisfactory results. Active ankle ROM was started at average 2.4 weeks ($2{\sim}4$ weeks) and full weight bearing ambulation at average 5.2 weeks ($4{\sim}8$ weeks) postoperatively. Union of fractures was obtained by average 14.4 weeks ($8{\sim}18$ weeks) postoperatively. Two cases showed $5^{\circ}$ limitation of motion without functional deficits and other cases showed satisfactory ROM results. One case had $6^{\circ}$ valgus deformity without functional deficits. There were not any other complications like soft tissue problems and delayed-or non-union. Conclusion: MIPPO technique for the treatment of distal tibial metaphyseal fractures is a feasible technique with a good clinical outcomes.

Purpose: In this study, we introduced an newly developed technique of operation for fracture of lateral malleolus of the ankle. We treated the fracture by close reduction and internal fixation using arthroscopy. Materials and Methods: From July 2006 to June 2007, we had treated 23 cases of lateral malleolar fracture (SER type) by closed reduction and internal fixation with arthroscopy and followed them up more six month. Operation time, union time, clinical and functional result were evaluated. Results: After the final follow-up, all the fractures were healed with satisfactory bony union. The subjective result was excellent in 15 cases (65%), good in 8 cases (35%), the objective result was excellent in 13 cases (57%), good in 10 cases (43%), and the roentgenographic result was excellent in 17 cases (74%), good in 6 cases (26%). Conclusion: Closed reduction and internal fixation with arthroscopy technique is an effective treatment method in treating lateral malleolar fracture of the ankle since it offers advantages including corrective anatomical reduction and minimizing complication associated with injury of soft tissue.

McKusick-Kaufman syndrome (MKS) is an autosomal recessive multiple malformation syndrome characterized by hydrometrocolpos (HMC) and postaxial polydactyly (PAP). We report a case of a female child with MKS who was transferred to the neonatal intensive care unit of Seoul National University Children's Hospital on her 15th day of life for further evaluation and management of an abdominal cystic mass. She underwent abdominal sonography, magnetic resonance imaging, genitography and cystoscopy which confirmed HMC with a transverse vaginal septum. X-rays of the hand and foot showed bony fusion of the left third and fourth metacarpal bones, right fourth dysplastic metacarpal bone and phalanx, right PAP and hypoplastic left foot with left fourth and fifth dysplastic metatarsal bones. In addition, she had soft palate cleft, mild hydronephroses of both kidneys, hypoplastic right kidney with ectopic location and mild rotation, uterine didelphys with transverse vaginal septum and low-type imperforated anus. She was temporarily treated with ultrasound-guided transurethral aspiration of the HMC. Our patient with HMC and PAP was diagnosed with MKS because she has two typical abnormality of MKS and she has no definite complications of retinal disease, learning disability, obesity and renal failure that develop in Bardet-Biedl syndrome, but not in MKS until 33 months of age. Here, we describe a case of a Korean patient with MKS.

The purpose of this study is to examine the dress and its ornaments of low-level officials shown in Tamna-Sullyeokdo, the paintings of the inspection tour of Jeju Island. The low-level officials Include low-level soldiers-sungjungun, gichigun, foot soldiers, cavalries, gunroe, ilsu, artillerymen, najang, and sawon-, musicians, servants, and kisaengs in government employ. 1. Different types of low-level soldiers tended to wear different kinds of clothes that is worn under an outer garment and to wear different coats and trousers depending on an outer garment. That is, sungjunggun, gichigun, foot soldiers, and cavalries were jeonbok over a jeogori and baji. On the other hand, gunroe, ilsu, artillerymen, and najang were houi or jakui over a jeogori and baji. However, Sawon simply were Jeonbok or armer or they wore Cheolik in formal occasions. 2. Musicians wore a jeonlib, a type of hat, decorated with an ear of barley and a red houi over a Jungchimak, a man's outer coat with large sleeves. Musicians wore colorful red clothes in order to add to the amusement during military trainings or banquets. 3. Servants in government employ had their hair in plaits and wore a jeonbok over a Jungchimak or baji and jeogori. However, when they dance during banquets, they were cheolik and jeonlib decored with/without an ear of barley or red flowers. 4. Gisaengs in government employ wore a gache on their head and wonsam, a woman's full dress during big occasions. They, on the other hand, wore a jeogoli and chima for regular occasions.

The functional disabilities post arthrodesis of the ankle include difficulty in climbing inclined surface, such as hill, ramps, or stair even through without pain. There will be periankle joints arthrosis as time passes. Total ankle replacement permits remobilization, no need for prolonged immobilization. There will be no increas in the mechanical stress of the neiboring joint. Total ankle replacement has been proposed as an alternative to arthrodesis in the management of painful arthrosis of the tibiotalar joint recently. We performed 7 cases of replacement from 1990. 4. 1 to 1996. 7. 1 with 2-3 years follow up. A retrospective review was undertaken for 7 patients with the arthrosis of tibiotatar joint. The results were as following. 1. The clinical results according to the point system for ankle study evaluation were excellent in 2 cases, good in 4 cases, and fair 1 case. 2. The improvement was especially obvious in terms of pain and functional recovery. 3. Total ankle replacement especially unconstrained type seems quite good alternative to arthrodesis.

Purpose: In previous study, the frequency of osteoarthritis and discomfort were high in ankle fracture-dislocation but detail results about ankle fracture-dislocation has rarely been investigated. In this study, we retrospectively analyze the outcome of the operative treatment of ankle fracture with dislocation for over-2 years follow up. Materials and Methods: There were 47 cases of ankle fracture-dislocation in our hospital from March 2007 to May 2010. We investigated 20 patients who underwent operation and were possible for over-2 years follow up. The result was estimated with the direction of dislocation, fracture type, the time of bone union and post-traumatic osteoarthritis with plain radiologic images. In clinical assessment, we statistically evaluated the function and pain through AOFAS score and Olerud & Molander scoring system. Results: By Lauge-Hansen classification, there were 13 cases(65%) of pronation-external rotation and 6 cases(30%) of supination-external rotation, 1 case(5%) of supination-adduction. AOFAS score was 85.5, and Olerud & Molander score was "excellent" in 8 cases, "good" in 5 cases, "fair" in 3 cases and "poor" in 4 cases. Postoperative complications in 4 cases revealed post-traumatic arthritis. All kinds of lateral dislocation of ankle fracture was 15 cases and the most common. Of these, all 3 cases, anterolateral dislocation showed post-traumatic osteoarthritis. Conclusion: In ankle fracture-dislocation, post-traumatic osteoarthritis occurred in 4 of 20 patient(20%). Especially, the possibility of post-traumatic osteoarthritis was more in cases of anterolateral or lateral dislocation. So, it must be needed that deliberate examination, for example, preoperative MRI and sufficient explanation to patient. Also, we have to follow up the patients carefully.

The powdery mildew of broad bean (Vicia faba) extensively occurred in farmers' fields in Changseon-myon, Namhae-gun, Gyeongsangnam-do, Korea in 2001. Both sides of the leaves and stems were covered with white fungal spores and mycelia, and then the leaves and stems colored brown and dark brown and eventually died. Conidia and conidiophores were formed on the lesion. Conidia were cylindric, 29~45$\times$13~23 um (av, 36~18 um) in size and born singly on the conidiophore. Fibrosin bodies were not observed. Conidiophores were straight with 3-4 cylindric cells and 51~100$\times$6~10 um (av.70$\times$8 um) in size. Foot cell was 28~53$\times$7~10 um (av,39$\times$8 um) in size. Appressorium was a lobed type. Cleistothecia were not formed. This is the first report on powdery mildew of broad bean caused by Oidium sp. in Korea.

Purpose: To propose a new comprehensive classification system of intraarticular calcaneal fracture based on CT images. Materials and methods: Fourty intraarticular calcaneal fractures which were treated operatively were evaluated retrospectively. We classified fracture types according to severity of comminution on the posterior facet and calcaneocuboid joint by CT images. And we evaluated postoperative results of each fracture types in terms of the quality of fixation and reduction by the postoperative plain radiograghs. Results: By the classification of the posterior facet, 18 cases were P-I, 15 were P-II, and 7 were P-III. Among the P-I cases, 7 were P-IA, 9 were P-IL, 1 was P-IM and 2 were P-IT. According to the classification of calcaneocuboid joint, II cases were C-I, 18 were C-II and 11 were C-III. Qualities of fixation were excellent in 27 cases (67.5%), fair in 9(22.5%) and poor in 4(10%). Qualities of reduction were excellent 23 cases(57.5%), fair in 11(27.5%) and poor in 6(15%). Conclusion: Our new classification system based on the CT images could provide informations about the fracture configuration and severity of comminution around calcaneocuboid joint as well as the posterior facet. And the high grade fractures such as type P-III are need to be taken care of fixation of articular surfaces.
