Several observation suggest that the antimelanocyte autoantibodies could play a role in melanocyte destruction. Some experiments indicate that melanocyte antibodies from patients with vitiligo can kill melanocyte in vitro. In these experiments, we demonstrated that vitiligo patient's sera containing antimelanocyte antibodies can lyse cultured human melanocytes by complement activation. Melanocyte cytotoxicity was measured using the ethidium bromide/ acridine orange viability assay. Significant melanocyte cytotoxicity was seen in sera from patients with both active and inactive vitiligo(p<0.01). Melanocyte cytotoxicity measured with complement-mediated cytotoxicity decreased after systemic steroid treatment(p<0.05) ; however melanocyte cytotoxicity showed no significant change with systemic PUVA therapy.

The author have statistically observed growth pattern of LBW infants born at NMC obstetric ward for 4 years form Jan. 1972 rtrough Dec, 1975. LBW infants were divided ino 2 groups, preterm and small-for-date infants and compared with normal full-term delivered infants group for height and weight. Following results were obtained 1) As compared with NFD infants group, preterm infants group revealed ststistically meaningful difference in height and weight until 5-6 months of age. Thereafter no difference was noticed. But, SFD group showed difference in height and weight until 1 year of age. 2) Preterm infants group was found to have a greater growth velocity than SFD group in 4-7 months of age, SFD group showed relatively similar increment of height and weight with NFD group. 3) Mean heght and weight of LBW infants were below NFD gronp until 1 year of age. Growth velocity ws similar with NFD group, so handicaps of LBW infants were not overcome statistically during 1 year after birth.

We report the implantation of a balloon-expandable intravascular stent at proximal left anterior decending artery in a patients suffered from Canakian functional class III angina for 8 years. The patient received 3 times percutaneous transluminal coronary angioplasty at proximal left anterior descending and circumflex artery without benefits. Repeated angiography revealed restenosis at proximal left anterior descending artery. Atherectomy was tried with transluminal extraction catheter(TEC) with luminal dissection and coronary bypass graft followed. occluded vein grafts were defined by follow-up angiography and chest pain recurred. No residual stenosis or thrombosis was documented in 24 hour follow-up angiography and the patient was discharged without symptom at 10 days after stenting.

5.A Case of Krabbe Disease.
Journal of the Korean Child Neurology Society 2001;9(2):411-415
Krabbe disease is an autosomal recessive neurodegenerative disorder that affects both the central and peripheral nerve system due to an enzymatic defect of galactocerebroside bata-galactosidase. The patient had typical clinical features of Krabbe disease, with irritability, hypertonicity, failure to thrive, and opisthotonic posturing. A brain MRI demonstrates profound white matter demyelination. The diagnosis of Krabbe disease is suspected on the basis of clinical pictures and confirmed by finding markedly reduced galactocerebroside bata-galactosidase activity in leukocyte or cultured fibroblast. Here we present the first reported case of Krabbe disease in Korea confirmed by decreased activity of galactocerebroside bata-galactosidase enzyme in leukocyte.

ACL plays an important role in stability of knee joint and its injury causes instability of joint which is known as the initiation of problem knee. Reconstruction of the anterior cruciate ligament would be preferred to the primary repair in treatment. And recently with the advance of arthroscopic technique and development of bone-patellar tendon-bone (BPB) graft material, the result of reconstruction is somewhat superior to that of primary repair. Authors compared the results of 20 primary repairs (Group I ) and 20 reconstructions (Group II) among 64 acute ACL injury treated Sung-Ae General Hospital from January 1989 to December 1994. The results were as follows: 1. Most common associated injuries were medial collateral ligament rupture and medial meniscal tear. 2. Group I showed postoperatively 13 negative anterior drawer test, 12 negative Lachmann test and 12 negative pivot shift test and group II showed postoperatively 17 negative anterior drawer test, 15 negative Lachmann test and 17 negative pivot shift test. (p<0.05) 3. In postoperative Lysholm knee scoring scale, group I showed 86 points and group II showed 93 points (p<0.05). 4. In postoperative KT-1000 arthrometer, 12 cases in Group I and 16 cases in Group II showed less than 2mm difference with sound side (p<0.05).

Traumatic dislocation of the hip presents serious problems that may lead to avascular necrosis, nerve palsy, post-traumatic arthritis even when reduction is promptly and adequately carried out. Among them avascular necrosis is the most important prognostic factor, so the early detection of this complication has critical significance for final result. Bone scan has been considered one of early diagnostic test, but recently MRI replaced its role for imaging in the detection of early AVN, treatment monitoring and prediction of prognosis. Authors prospectively studied the early finding of MRI to detect avascular necrosis of the femoral head and to predict prognosis in traumatic hip dislocation and fracture-dislocation. From December 1990 to November 1994, 12 case of dislocation and fracture-dislocation of the hip were studied . In follow up period ranging from 19 months to 65 months, 10 case had excellent or good result. All cases had abnormal MRI finding such as paraarticular edema, capsular bulging, joint effusion, femoral head fracture, but findings such as femoral head signal changes were dectected in only 3 cases. Among the 3 cases, 1 case had developed AVN and 2 cases were uneventful. Other complications were 3 cases of posttraumatic arthritis, 2 cases of incomplete sciatic nerve palsy, and 1 case of heterotrophic ossification. Although early MRI finding at posttrauma 2weeks gave less specific information, it could give good information for risk group and follow up control with more cases. Although it is expensive, MRI can be one of the most reliable reference in early diagnosis of AVN and prediction of prognosis in traumatic dislocation and fracture- dislocation of the hip with non-invasive method.

Fractures of the tibia are frequently encountered in mordern civilized society. Especially, those in distal 1/3 of the tibia have so many problems, such as angular deformity, osteomyelitis and nonunion because of anatomically scanty soft tissue. Many modalities of the treatment of fracture of distal 1/3 of the tibia were introduced. Among them, interlocking IM nailings were considered as one of the best modality. But, in interlocking IM nail, reaming of the medullary canal which destroys the endosteal circulation and causes thermal necrosis of the inner aspect of the cortical bone results in delayed union. And also, procedure for distal screw fixation is difficult and time-consuming. As for using flexible IM nails for fractures of distal 1/3 of the tibia, it was considered as not so satisfactory method due to lack of stability of fixation. However, the stability of fixation can be strengthened with fanning of the nails in distal fragment, using more than 3 nails and delay the protected weight bearing. Authors studied 25 cases of fractures of distal 1/3 of the tibia treated with closed flexible IM nailing at Sung Ae General Hospital, from July., 1987 to July., 1989, and obtained following results: 1. Among 25 cases, 4th decades were most common and males were more commonly involved. 2. Traffic accidents were the most common causes of injury and majority of 16 open fractures and 19 comminuted fractures, were caused by high energy mechanism. Among open fractures, type II were most common. 3. Two angular deformities less than 10 degrees, one proximal migration and one checkrein deformity were observed as complications, but, no clinically significant complications were noted. 4. The time for radiological union were 14.5 weeks in group without fibular fracture and 15.1 weeks in group with fibular fracture, and 14.0 weeks in closed fracture group and 17.2 weeks in open fracture group, and average in 15.6 weeks.
