BACKGROUND: The large surfaces of the skin are often initial site of contact between microorganism and human. The skin are coated with epidermis and epithelial cells can recognize microorganism and mount a fast defense through the production of various inducible antibiotic peptides. This leads to chracteristic broad spectrum of antimicrobial activity against bacteria, fungi, and viruses. Recent studies introduce us new peptides with antimicrobial activity such as P,-defensins and cathelicidins. They are expressed on the epithelia and polymorphonuclear leukocytes, which are first lines of defence from various invasive environments. Futhermore, they are considered very interesting and important endogenous antibiotics. Our previous study has shown that the expression of human defensin(hBD-2) mRNA, which is potent antibiotic peptide against Gram-negative bacteria(P. aeruginosa), was upregulated with ultraviolet(UV) irradiation, tumor necrosis factor-α(TNF-α) and lipopolysaccharide(LPS) in HaCaT cells. A novel hBD-3, 5-kDa, nonhemolytic antimicrobial peptide, was demonstrated a salt-insensitive broad spectrum of potent antimicrobial activity against many potentially pathogenic microbes in especially, multiresistant S. aureus. We have analyzed the expression patterns of hBD-3 in HaCaT cell lines. OBJECTIVE: This research have done in order to evaluate the expression and regulation of hBD-3 mRNA in human keratinocyte cell lines. METHODS: HaCaT cell lines were used to all culture experiments. Cultured human keratinocytes were stimulated with UV irradiation or TNF-α or LPS to determine whether hBD-3 mRNA production occurred. Reverse transcription-polymerase chain reaction (RT-PCR) was per-formed to amplify hBD-3 cDNA from stimulated keratinocytes in a time dependant manner, and densitometry was used to verify the specificity of RT-PCR amplication products. RESULTS: Expression of hBD-3 was upregulated with UV irradiation, TNF-α and LPS in Ha-CaT cells compared to control CONCLUSIONS: Human keratinocytes are capable to induce hBD-3 mRNA, as well as hBD-2, in response to UV irradiation, TNF-α and LPS. suggesting that these cells could play an important role against the bacterial infection and UV light damage in human skin.

Concurrent use of instrumentation has been shown to increase fusion rates and satisfactory results for surgical treatment of the lumbar stenosis. The objectives of the present study were to evaluate clinically and radiologically two groups of lumbar stenosis who were surgically treated with pedicular screw fixation system and posterior lumbar interbody or posterolateral autogenous bone graft following complete posterior decompression. One group was degenerative type and the other group was spondylolisthetic type spinal stenosis. We analyzed the results of 39 cases of lumbar stenosis who underwent pedicular screw and rod fixation system and posterior lumbar interbody or posterolateral autogenous iliac bone fusion following complete posterior decompressive operation during the period from May 1988 to December 1992. There were 27cases of degenerative type and 12 cases of spondylolisthetic type lumbar stenosis. The were 25 women and 14 men. Their age was ranged 20 to 76 years old with an average of 51.7 years old. The follow up period was the interval from 18 months to 6 years with an average of 3.2 years. The radiologic union rate was average 94.9% and 96.3%(26cases) in degenerative spinal stenosis and 91.7%(11 cases) in spondylolisthetic spinal stenosis. The clinical success rate was average 92.3%(36 cases), 88.9%(24 cases) in degenerative spinal stenosis and 100%(12 cases) in spondylolisthetic spinal stenosis. The patients with spondylolytic spinal stenosis showed better result in their life than the patient with degenerative spinal stenosis.

PURPOSE: We performed this study to evaluate the changes of gallbladder ejection fraction (GBEF) in diabetic patients with or without autonomic neuropathy. MATERIALS AND METHODS: This study included 37 diabetic patients (25 women, 12 men, mean age 51 years) and 24 normal controls (10 women, 14 men, mean age 38 years). After intravenous injection of 185 MBq of 99mTc-DISIDA, serial anterior abdominal images were acquired before and after fatty meal. Regions of interest were applied on gallbladder and right hepatic lobe on 60 and 90 minute images to calculate GBEF. RESULTS: GBEF was significantly reduced in diabetes with autonomic neuropathy (43+/-12.3%) and without autonomic neuropathy (57.5+/-13.2%) compared with normal controls (68+/-11.6%, p <0.05). And also, GBEF was significantly reduced in diabetes with autonomic neuropathy compared with diabetes without autonomic neuropathy (p <0.05). Fasting blood glucose level, age, sex, hemoglobin A1c, body mass index, serum lipid level were not different in these two diabetic patient groups (p>0.05). When 50.2% of GBEF was used as the criteria for diabetic autonomic neuropathy, the sensitivity and specificity were 80%, 76.5%, respectively. The area under receiver operating characteristic curve was 0.846. CONCLUSION: GBEF of diabetic patients with autonomic neuropathy was significantly reduced than that of diabetic patients without autonomic neuropathy.

Polymyositis is uncommon, nonsuppurative Connective tissue disorder. We have experienced a case of polymyositis. Patient was a 20-y.ear old female in good healthy appearance with history of mild, progressive muscle weakness of lower extremities and inability to walk up and down of stairs in recent 3 weeks. Her symptoms were mainly subjective and individual muscle test revealed no abnormalities, but evidences of primary myopathy were easily obtained by muscle biopsy, electromyogram and several enzyme values. We are reporting a case of polymyositis with brief review of literature.

We are reporting a case of molluscum contagiosum in a 3-year-old boy who showed a good response to diphenylcyclopropenone (DPCP) immunotherapy. The lesions were multiple, 2 to 7mm in size, centrally umbilicated, normal skin-colored papules of 7 months' duration which were distributed on the penoscrotal area, extremities and trunk. In spite of several treatments using extraction and curettage, new lesions developed continuously. The patient was sensitized with 0.1ml of 1% DPCP solution in acetone on his right shoulder and there-after challenged with solution of varying concentrations (0.05 to 0.1%) on his left shoulder once or twice a week to maintain a mild eczema. Clinical improvement was noted 1 week after sensitization and almost all of the lesions cleared after 8 week's treatment.

Treatment of male urinary incontinence is one of the most distressing problem in the urologic practice. Recent advances in implantable devices have improved the outlook for patients with incontinence, but the prosthetic surgery has mechanical problems to be solved, and does not maintain physiologic normality. Recently, we treated a case of postprostatectomy incontinence, and obtained a good result with surgical intercavernous embedding of the bulboperineal urethra.
