OBJECTIVE: Behcet? disease (BD) is a chronic inflammatory disorder affecting several organs. The etiology of BD remains unclear, although genetic factors, infectious agents, and immune mechanisms have been studied. The association of BD with certain genetic factors, especially HLA-B51 antigen, is well known in some geographical areas. Nevertheless, the familial occurrence of BD is rare. In this paper, HLA phenotype was evaluated in one family member showing the clustering of BD. METHODS: The serological tissue typing of HLA class I and class II antigens was performed by standard National Institutes of Health microlymphocytotoxicity method in seven family members in which four siblings were affected by BD. The diagnosis of BD was established by the criteria of the International Study Group of BD in these four siblings. RESULTS: In this family study, all members had HLA-A2 and DQ3 antigens. Although HLA-B51 antigen was positive in six out of seven family members, BD was developed in three of the six having HLA-B51 antigen. Three siblings had the exact same HLA phenotype. However, only one person had BD among three siblings with identical HLA phenotype. In addition, all siblings who developed erythema nodosum-like lesion had HLA-B51 antigen. CONCLUSION: This family suggests that the familial clustering of BD may not be explained solely by a susceptible HLA phenotype. The environmental factor or other genetic factors besides HLA-B51 might play a role in the development of BD. Furthermore, more studies and information will be needed to clarify the role of A2 and DQ3 antigens in BD.

The ankle is a modified hinge joint consisting of tibial plafond, medial and lateral malleolus, talus and many soft tissue structures, which plays important role in weight bearing and walking. Hence, the ankle injuries include not only fractures of bone but often also the rupture of ligaments and soft tissues, so if the structures were not accurately repaired, many complications may develop. The authers analysed 98 cases (96 patients) of the ankle fractures which were admitted and treated in Orthopaedic Department, Soon Chun Hyang University Hospital from January 1979 to August 1983. The results obtained are as follows: 1. Of the 98 cases, male was 70 cases(71.9%), female was 28 cases and the average age of the patient was 31,1 years. 2. The most common cause of the fracture was traffic accident and the other causes were slip down, sports injury, fall down and industrial injuries in order. 3. 83 cases(84.7%) out of the 98 cases of ankle fractures were closed fracture and the rest was open fracture. 4. The most common type of the ankle fracture, according to the classification of Lauge-Hansen, was supination external rotation type. 5. 68 cases were treated with open reduction and internal fixation and 30 cases were treated with closed reduction, among the cases of closed reduction, the 14 cases were indicated to open redu- ction but it was impossible due to improper skin condition, severe comminution and anesthetic problem. 6. The average duration of the cast immobilization in closed treatment was 10.1 weeks and in operative treatment was 6.3 weeks. 7. The results of the treatment was better in those cases of the open reduction, the early reduction and the mildly displaced cases than the results of closed reduction, delayed reduction and severely displaced cases. 8. The incidence of complication, such as traumatic arthritis and nonunion occured higher in the cases treated with closed method.

The slipped capital femoral epiphysis is characterized by a growth disturbance of the capital physi. resulting in weakening of this structure and a subsequent displacement of the femoral head on the fe moral neck. It is a rare entity in Korea and only six cases have been reported so far1-5). One of ou cases was a bilateral mild acute slips in 13 yearold boy which were treated by Hagie pinning. Th other case, a 17 year-old boy, who suffered from a moderate acute on chronic slip in his left hip an showed a typical Pistol grip deformity. He was treated by gentle closed rcduction and Knowles pi fixation with good result.

When the multiple myelographic defects at lumbosacral region are noted, the prudential effort for decision of appropriate area of surgical decompression would be needed. Fifty four patients who had been treated surgically for the deseases, such as HNP and spinal stenosis, from March in 1982 to Feb. In 1987 at Department of Orthopecdic Surgery, Soonchunhyang University Hospital, were analyzed in order to define the etiology, the level of the defect, indication for the operation and to assess the results of each level which had been operated. The results of the study were as follows. 1. The number of patients, which the multiple indentations were noted in the myelogrsphy, was 54 cases, 29 spinal stenosis, 15 HNP and 10 mixed types. 2. The most common defect levels in myelography were L3-4 snd L4-5, which were 19 cases (35.2%), the next levels were L4-5 and L5S1, which were 16 cases(29.6%), then L3-4, L4-5 and L5S1 were 7 cases(13%) and the other levels were 12 cases(22.2%). 3. The decision for the sppropriste operation area had not be done following to the size of the myelographic defect, but the clinical symptoms and physicsl exsminations. 4. The results were classified ss excellent or good in 79.7%, which was 80% at two levels snd 79.5% at one level. 5. The operation levels could be decressed for the reducing the spinal instability, operation time and possibility of the dangerous conditions and promotion of early restoration and, ambulation, if the severe differences between the results of one and two operation levels were not seen.

Carcinoid tumors are well-differentiated epithelial neoplasms that usually can be diagnosed without difficulty based on their distinctive histologic patterns. These tumors are composed of variable numbers of calls that contain endocrine secretory granules in their cytoplasm, which can be identified by histochemistry, immunohistochemistry, and electron microscopy, Carcinoid tumors of the duodenum are relatively rare, the reported incidence being 2.0-8.9% of all gastrointestinal carcinoid tumors dianosed in Western countries. The rate of occurrence among all duodenal tumors is 3-5.5%. We experienced a case of carcinoid tumor of the duodenum in a 53 year-old male patient. He was admitted to our hospital because of epigastric pain. On the gastrofiberscopic examination, 0.7 cm sized Yamada type II polyp with central ulceration was noticed on the duodenal bulb. The biopsy specimen revealed carcinoid tumor. He was treated with polypectomy.

OBJECTIVE: Transcranial magnetic stimulation (TMS) is a new, noninvasive procedure of a localized pulsed magnetic field to the surface of the head to cause a depolarization of neurons in the brain cortex underneath. Knowledge of the neuroanatomic abnormalities of depression is serving as the background for TMS treatment in depression. Here we provide a summarized review of the therapeutic application of TMS in patients with depression. METHODS: We described the clinical and basic researches of TMS in depression and integrated the future direction using literature review and interview with experts. RESULTS: The field of TMS is beginning to address the issues of using TMS as a novel antidepressant. The ability to excite local areas of brain cortex has raised the possibility of the use of TMS as a novel therapeutic tool for depression. CONCLUSIONS: Many parameters, such as intensity, location, frequency, pulse width, intertrain interval, coil type, duration, numbers of sessions, and interval between sessions remain to be systematically explored. However TMS would be a relatively new and noninvasive method to investigate regional brain activity and to treat depression.

Behcet's disease (BD) is a chronic inflammatory condition involving several organs, such as skin, mucous membrane, eye, joint, intestine, lung and central nervous system. Ankylosing spondylitis (AS) is a prototype of seronegative spondyloarthropathy, and a chronic systemic inflammatory disorder of the axial skeleton, mainly affecting the sacroiliac joint and spine. In the latter, systemic complications may develop in addition to joint involvement. The coexistence of BD and AS has been rarely reported in the literature. The inclusion of BD among seronegative spondyloarthritides and whether sacroiliitis (SI) develops in BD are still being debated. We describe a 28-year-old man who has fulfilled the diagnostic criteria for BD and AS as well.

STATEMENT OF PROBLEM: In order to increase preload with reducing the friction coefficient, abutment screws coated with pure gold and Teflon as dry lubricant coatings have been introduced. But the reported data indicate that if screw repeated tightening and loosening cycle, an efficiency of increasing preload was decreased by screw surface wearing off. PURPOSE: This study was to evaluate the influence of tungsten carbide/carbon coating, which has superior hardness and frictional wear resistance, on the preload of abutment screws and the stability of coating surface after repeated closures. MATERIAL AND METHOD: The rotational values of abutment screws and the compressive forces between abutment and fixture were measured in implant systems with three different joint connections, one external butt joint and two internal cones. Moreover, the stability and the alteration of coating surface were examined by comparison of the compressive force and the removable torque values during 10 consecutive trials, observation with scanning electron microscope and analyzed the elemental composition with energy dispersive x-ray spectroscopy. RESULTS AND CONCLUSION: 1. Application of coating resulted in significant increase of compressive force in all implant systems(P<.05). The increasing rate of compressive force by coating in external butt joint was greater than those in internal cones(P<.05). 2. Coated screw showed the significant additional rotation compared to non-coated screw in all implant systems(P<.05). There were no significant differences in the increasing rate of rotation among implant systems(P>.05). 3. Removable torque values were greater with non-coated screw than that with coated screw (P<.05). 4. Coated screw showed insignificant variations in the compressive forces during 10 consecutive trials(P>.05). 5. After repeated trials, the surface layer of coated screw was maintained relatively well. However, surface wearing and irregular titanium fragments were found in non-coated screw.

PURPOSE: Experimental autoimmune uveoretinitis (EAU) is an animal model of posterior uveitis and heme oxygenase-1 (HO-1) is a well-known anti-oxidant factor. However, there is no report a protective role of HO-1 on EAU in vivo. To verify that HO-1 is induced in EAU by interphotoreceptor retinoid-binding protein (IRBP), that an HO-1 inducers ameliorates the associated inflammation, and that an HO-1 inhibitor exacerbates this inflammation. METHODS: Forty four Lewis rats were given either 40 mol/kg hemin or 40 mol/kg SnPP (tin protoporphyrin IX) by intraperitoneal injection and twenty two uveitis control rats were injected with 0.5 mL of saline once daily 5-20 days after IRBP immunization inducing EAU. Three normal control rats were used for Western blotting and ELISA assay of HO-1. The clinical uveitis signs of inflammation were scored in the three groups from 0 to 4 on alternate three days. To confirm the clinical results, histological and immunohistochemical stain of HO-1 were performed on the day of peak inflammation and Western blotting and ELISA assay of HO-1 were performed on 6th, 12th and 18th day after IRBP immunization. RESULTS: Hemin, an inducer of HO-1, ameliorated the clinical signs of EAU. In contrast, SnPP-treated rats show that the severity of the clinical sign were exacerbated at the peak period of the disease. These results are roughly compatible with histological, immunoblotting, and immunohistochemical evaluations and an ELISA assay of HO-1. CONCLUSIONS: We suggest that HO-1 plays an important protective role in EAU.
