Plasmid vectors with either RSV or CMV promoter are frequently used for DNA- mediated immunization due to the availability in commercial. Consequently, influence of the vector constituents, such as promoter, enhancer and transcription termination signal etc. on vaccination efficiency is not studied extensively. As an initial attempt to develop an efficient vector system for DNA-rnediated immunization, influence of promoter for antigen gene expression on vaccination efficiency has been analyzed. Initially, plasmids with either B-actin or muscle creatine kinase (MCK) promoter were constructed from the plasmid with prototype CMV promoter. In addition, ovalbumin (OVA) antigen gene has been cloned into each vectors to generate the plasmid vectors with different promoters for induction of the anti-OVA immune responses. Antigen protein expression in antigen gene transfected mouse muscle myoblast cells showed that the level from MCK promoter containing plasmid was slightly higher than those from either CMV or B-actin promoter containing plasmids. Also, the same plasmid turned out to be slightly more efficient than other plasmids in antibody imrnune response induction in vivo, when they were applied both through intramuscularly and intradermally. These results suggest that the commonly used CMV promoter containing plasmid vector could be further modified to develop an efficient vector for DNA-mediated immunization.

We report a patient who had been initially diagnosed as a myelodysplastic syndrome in 1998 presenting purpuric patches on the left arm that started to develop about a year prior. The purpuric lesions were diagnosed as leukemia cutis by skin biopsy. Her subsequent bone marrow biopsy showed progression into an atypical chronic myeloid leukemia with increased numbers of leukocytes in the peripheral blood. Leukemia cutis typically is regarded as a sign of progression of disease or a manifestation of recurrent disease in treated patients with an established diagnosis of leukemia. We suggest that the skin lesion in this patient could have been a sign of con-version into atypical chronic myeloid leukemia.

Acute generalized exanthematous pustulosis(AGEP) is a disease entity caused mostly by drugs or viral infections. Clinically it manifests as generalized erythema, erythema multiforme and amicrobial pustules with fever. Histologically, AGEP is composed of neutrophilic subcorneal and spongiform pustules. A 70-year-old female, with no personal or family history of psoriasis, was given medication including diltiazem for hypertension. Fourteen days after taking the medications, pustular eruptions appeared on the face and rapidly spread to the trunk and limbs. A Laboratory examination revealed neutrophilic leukocytosis and an elevated erythrocyte sedimentation rate. The skin biopsy showed subcorneal and spongiform pustules. We report here a case of AGEP probably due to diltiazem.

The fractures of the ankle in children are differ from those of adults in terms of the fracture pattern and the possibilities of influence to growth. The injuries of the ankle in children occur mostly at the bony structure rather than ligamentous structure, and some injuries of the growth plate may result in the arrest of entire growth plate or parts of growth plate and these may lead to leg length discrepancy or deformity. Many authors agree that the prognosis of injuries of the growth plate is dependent on the fracture type, the age of the patient at the onset of injuries, the degree of displacement of the fracture fragments, whether the injuries open or closed, and the efficacy of reduction. But the authors can not postulate one uniformed method of classification and treatment of the children's ankle fracture because of the variability of injuries. We have reviewed 35 cases of children's ankle fracture treated at our clinics from Dec. 1979 to Feb. 1984. The results obtained are as follows: l. Over half of the patients were between the ages of 13 and 16 years (54.3%). 2. The incidence of each type as Salter-Harris classification was that of type II(48.6%), type I(20.0%),type III(14.3%),type IV (8.6%). 3. The traffic accidents were the main causes of injury (68.5%). 4. The type I fractures occured mostly under 10 years of age and the type II fractures in adolescents. 5. All the type I fractures were treated conservatively without any complication, and the type II fractures were treated conservatively in 13 cases (76.5%) and operatively in 4 cases (23.5%) with variable results. 6. Overall incidence of complication was 20.0%, consisted with two cases of conservatively treated but not accurately reduced type II fractures, a conservatively treated type III fracture, a triplane fracture, and the others.

PURPOSE: Recent studies have revealed close relationships between hepatic injury, metabolic pathways, and gut microbiota. The microorganisms in the intestine also cause irritable bowel syndrome (IBS). The aim of this study was to examine whether IBS was associated with elevated hepatic enzyme [alanine aminotransferase (ALT) and aspartate aminotransferase (AST)], gamma-glutamyl transferase (gamma-GT) levels, and metabolic syndrome (MS). MATERIALS AND METHODS: This was a retrospective, cross-sectional, case-control study. The case and control groups comprised subjects who visited our health promotion center for general check-ups from June 2010 to December 2010. Of the 1127 initially screened subjects, 83 had IBS according to the Rome III criteria. The control group consisted of 260 age- and sex-matched subjects without IBS who visited our health promotion center during the same period. RESULTS: Compared to control subjects, patients with IBS showed significantly higher values of anthropometric parameters (body mass index, waist circumference), liver enzymes, gamma-GT, and lipid levels. The prevalences of elevated ALT (16.9% vs. 7.7%; p=0.015) and gamma-GT (24.1% vs. 11.5%; p=0.037) levels were significantly higher in patients with IBS than in control subjects. A statistically significant difference was observed in the prevalence of MS between controls and IBS patients (12.7% vs. 32.5%; p<0.001). The relationships between elevated ALT levels, MS, and IBS remained statistically significant after controlling for potential confounding factors. CONCLUSION: On the basis of our study results, IBS may be an important condition in certain patients with elevated ALT levels and MS.

Fibrolipoma is an uncommon variant of lipomas which shows a distinct pathologic findings with both component of mature adipose cells and broad bands of dense fibrous connective tissue. A 30-year-old woman developed an 5×7cm sized, indurated, ill-defined, subcutaneous mass on the right axilla. Microscopically, the tumor contained broad bands of dense connective tissue with mature adipose tissue scattered throughout the mass, but it did not show encapsulation. The lesion was excised and she showed no evidence of recurrence after 6 months of follow-up.

PURPOSE: The purpose of this study was to test the effectiveness of a comprehensive smoking cessation program for Korean adolescents. METHOD: The study design was quasi-experimental with one pre and three post-tests. The three posttests were done immediately after, three months later, and six months after the completion of the program. A total of 43 high school students who smoked participated in the study with 22 in the experimental group and 21 in the control group. The smoking cessation program consisted of 9 sessions with content on enhancement of self-efficacy, stress management, correction of distorted thoughts, consciousness raising, and assertiveness training. The study variables were urine cotinine levels, self-efficacy, stress, and stages of changed behavior. RESULTS: Urine cotinine levels significantly decreased in the experimental group after the program (F=3.02, p=.06) but significantly increased in the control group (F=6.32, p=.004). Self-efficacy and the degree of stress did not change in either group. The stages of smoking cessation behavior tended to change when compared with raw data for the experimental group. For most participants, the stages of change had been precontemplation and contemplation, but changed to action and maintenance stage among the experimental group. CONCLUSION: The program was effective in smoking cessation and influencing stages of change but did not change psychosocial factors such as self-efficacy and stress. It is suggested a program should be developed to change psychosocial variables on a long-term basis. It is also desirable to involve peers and families of adolescents who smoke when planning programs to enhance social support.

BACKGROUND: Pyoderma gangrenosum is a rare disease in which a painful nodule or pustule breaks down to form a progressive enlarging ulcer. Until now, only 8 cases of pyoderma gangrenosum have been reported in Korea. Therefore, we thought it necessary to perform a clinical analysis of pyoderma gangrenosum in Korea with a review of literature. OBJECTIVE: Our purpose was to find the clinical features of pyoderma gangrenosum in Korea. METHODS: Fourteen cases with pyoderma gangrenosum were investigated by reviewing medical records. Results There were 6 males and 8 females. The onset age was between 4 years and 65 years, and most(9 cases) had developed the condition between the ages of 20 and 60. Thirteen cases involved the extremities and 3 cases had whale body involvement, Seven cases(50%) had multiple lesions. All cases had pain at the lesional sites. Two cases were classified as the bullous type and the others were ulcerative in nature. The histological fmdings were non-specific. Dense inflarnmatory infiltrates composed of lymphocytes and predominant neutrophils were found in the epidermis and dermis associated with ulceration. Two cases were treated only with systemic steroids, and 2 cases with dapsone and steroids, 2 cases with colchicine and steroids, and 1 case with steroids, dapsone and colchicine. One case was treated with colchicine and anti-Tbc drug, 1 case with dapsone, 3 cases with antibotics, 1 case with the anti-Tbc drug and 1 case with anti-cancer drugs. Systemic disease was present in 5D% of the cases. The associated diseases were Behcets disease(3 cases), tuberculosis(2 cases), systemic lupus erythematosus(1 case), pancytopenia(1 case), iron deficiency anemia(1 case), acute leukemia(1 case), and colon adenoma(1 case). Recurrence developed in 2 cases and positive pathergy reactions were observed in 3 cases. CONCLUSION: Pyoderma gangrenosum was eccompanied with systemic disease in 50% of the cases and the most common therapeutic drugs were steroids. It is therefore impartant to detect the presence of any underlying disease and to treat this alongside pyoderma gangrenosum.

Chondroid syringoma is a rare primary skin tumor arising from eccrine sweat gland. In 1982, Nasse had found a primary skin tumor having similar morphology as in the mixed tumor of the salivary glands. In 1961, Hirsch and Helwig proposed more descriptive diagnostic term, "Choindroid syringma". The authors experienced two cases of chondroid syringma. The first case was a 47 year old male patient who had had a subcutaneous nodule in the right forehead for two months. It was a well circumscribed mass, that showed tan gray myxoid cut surface with firm consistency. Microscopically, it was a wel diagnosed as chondroid syringoma with tubular, branching lumina. The second case was a 51 year old female patient who had had a subcutaneous nodule in the left forehead for 3 months. It was well circumscribed, ad easily shelled out. It had a typical microscopic features of chondroid syringoma with small, tubular lumina.
