Antinuclear Antibodies in Patients with Behcet's Disease / 대한피부과학회지

BACKGROUND: Behcet's disease has features consistent with an immunopathogenic mechanism, but the autoreactivity in pathogenesis is unclear. OBJECTIVE: This study was to investigate the association of antinuclear antibodies (ANA) with Behcet's disease. METHODS: The patients in this study were diagnosed at Severance Hospital Behcet's Disease Specialty Clinic from May, 1998 to May, 2002. We evaluated the frequency, titers and immunofluorescence patterns of ANA in patients with Behcet's disease, and compared the frequency with a healthy control group. According to the positivity of ANA, we compared the frequency of minor symptoms to investigate the association of the severity of disease with ANA. RESULTS: 1. Of the 554 cases of Behcet's disease, 46 cases (8.3%) were ANA positive, however, of the 271 cases of healthy control group, only 5 cases (1.8%) were ANA positive. (p=0.0003) 2. In ANA titers 38 cases (82.6%) showed low titer (1: 40+, 1: 160-), 5 cases (10.9%) intermediate titer (1: 160+, 1: 640-), and 3 cases high titer (>1: 640+). There was no significant difference in intermediate and high titers between complete (17.9%) and incomplete type (14.3%). 3. In immunofluorescence patterns of ANA, 17 cases (37%) were speckled pattern, 5 cases (10.9%) homogeneous pattern, 3 cases (6.5%) centromere pattern, 2 cases (4.3%) nucleolar pattern and 19 cases (41.3%) unknown pattern. 4. Of 508 cases with negative ANA patients, 272 cases (53.5%) had minor symptoms, however, of 46 cases with positive ANA patients, 14 cases (30.4%) had minor symptoms (p=0.0027). CONCLUSION: From this study ANA was more prevalent in Behcet's disease. However, it was not related to severity of disease and most of them were low titer. ANA, herein, might play a minor role in pathogenesis of Behcet's disease.

Behcet's Disease: The First Mongolian Case in Literature Showing HLA B51, MICA Gene Type *5/*6

Behcet's disease is a chronic multi-systemic disease of unknown origin that includes mucocutaneous, ocular, cardiac, vascular, renal, gastrointestinal, neurologic and cutaneous involvement. The disease is spread throughout the world, but it is most prevalent in the eastern Mediterranean region-along the Silk Road-, and in Japan, China, and Korea. Recently, we treated a Mongolian patient who had complete-type Behcet's disease. As far as we know, this case is the first report of a Mongolian with Behcet's disease in the English literature. HLA typing in this patient revealed A2, A24; B51, B35; Cw4, Cw7; DR9, DR11. Study of the MICA genetype showed *5, *6 positive. Our data provided adequate evidence, from an epidemiological aspect, to support the belief that Behcet's disease is most prevalent along the old Silk Road.

Intercellular adhesion molecule-1 polymorphisms in Korean patients with Behcet's disease

Intercellular adhesion molecule-1 (ICAM-1) is expressed on vascular endothelial cells and its expression increases during the inflammatory response in patients with active Behcet's disease (BD). The ICAM1 gene mutations are associated with BD in Caucasians, but clinical features of the mutation phenotype are unknown. We analyzed ICAM1 polymorphisms in Korean BD patients to determine if there was an association between particular mutations and clinical symptoms. The prevalence of ICAM1R241G and ICAM1K469E polymorphisms was determined among 197 patients with BD and 248 healthy controls using BsrG1 and BstU1 PCR-RFLP. The frequency of both genotypes ICAM1469 * K/ * E and ICAM-1469 * E/ * E was significantly higher in BD patients compared with controls (66.0% vs 52.4%, p=0.004, OR=1.28, 95% CI 1.08-1.50) and the allele frequency of ICAM1469 * E was higher in patients with skin lesions (0.41), genital ulcers (0.41), vasculitis (0.43), ocular lesions (0.41) and arthritis (0.39) than in controls (0.31). Only one heterozygote, ICAM1241G/R, was detected in BD patients but the ICAM1241 * R mutation was not found in any of the 248 healthy controls. These results show that the ICAM1 mutation is associated with BD susceptibility, and is another genetic risk factor for BD among the Korean population.

A 33-year-old woman developed a pea-sized, painless, pedunculated nodule on the right palm. Microscopically, it consists of an intricate mixture of lipocytes and uniform spindle cells that was closely associated with a varying number of short bundles of collagen fibers. The lesion had been excised and showed no evidence of recurrence.

A Study of Interleukin-2 Activity in Behçet's Syndrome

This study was undertaken to investigate immunological mechanisms in Behçet's syndrome, a function considered important in the pathogenesis of the disease. The activity of interleukin-2 (IL-2), which is believed, to play a central role in the regulation of both cell-mediated and humoral T cell-dependent immune responses, measured in 46 patients with complete, in-complete or suspected Behçet's syndrome. The results were as follows: 1 . There was no significant difference between the average IL-2 activity of patients and control group. 2. For each clinical subtype of Behçet's syndrome, IL-2 activity was lower than the control value, but the difference was not statistically significant. 3. In mucocutaneous and ocular types, the greater the clinical symptoms, the lower the value of IL-2 activity. However, the decrease of IL-2 activity was not statistically significant. In conclusion, IL-2 activity of phytohemaggludnin (PHIS-stimulated peripheral blood lymphocytes in patients with Behçet's syndrome was not significantly decreased compared to control population.

Isolation and Identification of Melanosomes from Human Hair

Melanosomes were isolated from the human hair by graded centrifugation and identified by transmission and scanning electron microscopic examination. Melanosomes were separated from the keratinous structures by treating with strong NaOH solution for 15 hours. The keratinous structures were removed by centrifugation ai 2,500xg and 3,500xg for 10 minutes respectively at 0 ℃. The isolated melanosomes were collected by centrifugation at 7,800xg at 0 ℃. Scanning electron microscopic examination made it possible to evaluate the global structure of purified melanosomes.

Two Cases of Goltz Syndrome

Goltz syndrome, also known as focal dermal hypoplasia syndrome, is a rare congenital mesoectodermal disorder. Two cases, which we experienced, showed erythematous, tan skin rashes and atrophic scars on the whole body, but there were some differences in clinical manifestations. Histopathologic findings in both cases showed diminution in the thickness of the dermis with subcutaneous fat extending upward to the epidermis. Therefore, we report a comparison of two cases of Goltz syndrome, especially with respect to clinical manifestations.

A Study of Leukocyte Migration Inhibition Factor in Behcet's Syndrome / 대한피부과학회지

This study was undertaken to investigate the immunological mechanism of Behqet s syndrome, considered to be important in the pathogenesis of the disease. Seventy- three patients with complete, incomplete and suspected types of Behget's syndrotne were tested for leukocyte migration ingibition factor(LIF), one of the lymphokines. The results were as follows : 1. There was no difference between the average LIF activity of all the patients and that of eontrol. 2. LIF activity of complete type, according to Shirnizus classification, was significaritly lower than the control value. 3. LIF activity of ocular type, according to Lehners classification, was signficantly lower than the control value. 4. LIF activity for patients with 4 clinical symptoms was well below the value for patients with less symptomes 5. For patients with single clinical symptom, LIF activity of complete type was well below the values of incomplete and suspected types. 6. In suspected and mucocutaneous types, LIF activity was low when the patients showed two clinical symptoms than one. Thus, LIF activity was low for patients with complete, ocular and neurological types and with multiple symptorns.

A Morphological Study of Stratum Corneum / 대한피부과학회지

Stratum corneum was obtained from 10 healthy individuals aged 23 and 24 years, in order to observe morphological differences in a three-dimensionsl structure of stratum corneum from 3 anatomical sites, i. e., flexor surface of the forearm, abdomen, and palm. The stratum corneum obtained by the skin surface biopsy was ohserved under a scanning electron microscope(SME). The surfaces of stratum eorneum obtained by the replice, technique were observed under a stereomicrascope(SM). The results were as follows : 1) SEM observation of the posterior surfaces of the stratum corneum from the skin surface biopsies of the flexor surface of the forearm and abdomen showed divisions with folding lines which were elliptic in the forearm and squere in the abdomen. But there were no similar folding linea in the palm. Among the 3 anatomiral sites, overlapping corneocytes on the palm were most prominent. On a higher magnification, small pits and fine wrinklings in the forearm, fine wrinklings in the abdomen, and villous projections in the palm were observed respeeti vely. 2) SM observation of the stratum corneum from the negative replica of the flexor surface of the forearm, abdomen, and palm showed divisions with folding lines which were X-shape a.t the site of their crossinga in the forearm, *-shape in the abdomen, and linear shape in the palm, Among the 3 snatomical sites, tiny holes on the palm were most prominent. Follicular openings were observed on the pa1m, and abdomen,

Excretion of Trace Element into Thermal Sweat / 대한피부과학회지

Using atomic absorption spectrometry Pb, Cd, Cu, Zn and Fe were measured in sweat and Pb, Cd, Cu and Zn, in blood. The subjects were 22 healthy males, aged between 23-44. Sweating was induced with an environmental room (1 hour at 46C dry bulb and 36C wet bulb). Sweat samples were obtained from the left arm by the armbag technique. The sweat volume was 23.3+7.3ml(n= 22). The concentrations, in ug/ml, of trace elements in sweat were : lead, 0.18+0.17(n=22); cadmium, 0.006+0.006(n=22); copper, 0.37+0.66(n=10); zinc, 0.63+0.5(n=10); and iron, 0.22+0.12(n=10). The concentrations, in ug/ml, of trace elements in blood were : lead, 0.28+0.15(n=20); cadmium, 0.005+0.007 (n=20); copper,0.69+0.22(n=20); and zinc,5.61+0.86(n=20). These results clearly showed the significance of sweating as a route of excretion of trace element.
