In spontaneous hair loss of C57BL/6N mice model, we investiged the factors related to hair loss by microscopic and immunocytochemical methods. The results were as follows; Microsopic observation of sebaceous gland was developed, and subcutaneous layer was thin in SA and AU group. Number of mast cells in SA and AU group was more increased than that of other groups. Number and immunoreactive density of CD4/CD8 lymphocytes was more increased than that of other groups. Immunoreactivity of substance P and CRF was weakly stained in stem cell region of SA and AU group. Immunoreactivity of CRF-R and CRF-BP was weakly stained in stem cell and bulge regions of SA and AU group. Immunoreactivity of stem cell factor was weakly stained in stem cell, bulge region and dermal papilla of SA and AU group. These experiment suggest that factors related to hair loss in spontaneous hair loss C57BL/6N mice models are increased of mast cell, CD4 and CD8 lymphocytes, and decreased of cytokine and neuropeptide in stem cell, bulge region and dermal papilla.

This is a cross-sectional observational study undertaken to explore the current prescription pattern of non-steroidal anti-inflammatory drugs (NSAIDs) and the prevalence of NSAID-induced gastrointestinal (GI) risk factors of orthopaedic patients in real clinical practice in Korea. Study cohort included 3,140 orthopaedic outpatients at 131 hospitals and clinics between January 2008 and August 2008. A self-administered questionnaire was completed by each patient and physician. A simplified risk scoring scale (the Standardized Calculator of Risk for Events; SCORE) was used to measure patients' risk for GI complications. The pattern of NSAIDs prescription was identified from medical recordings. Forty-five percents of the patients belonged to high risk or very high risk groups for GI complications. The cyclooxygenase-2 enzyme (COX-2) selective NSAID showed a propensity to be prescribed more commonly for high/very high GI risk groups, but the rate was still as low as 51%. In conclusion, physician's considerate prescription of NSAIDs with well-understanding of each patient's GI risk factors is strongly encouraged in order to maximize cost effectiveness and to prevent serious GI complications in Korea. Other strategic efforts such as medical association-led education programs and application of Korean electronic SCORE system to hospital order communication system (OCS) should also be accompanied in a way to promote physician's attention.

BACKGROUND: Broncholithiasis is uncommon but clinically important because it may cause a variety of nonspecific symptoms and signs prior to the onset of lithoptysis, and rarely massive hemoptysis. METHOD: A retrospective clinical study was done on 11 case of broncholithiasis diagnosed at Kyungpook National University Hospital from Jan. 1985 to Dec. 1993. The study investigated the clinical features, radiologic findings, bronchoscopic findings and management. RESULTS: 1) The common symptoms included cough, dyspnea, hemoptysis, fever and purulent sputum. Lithoptysis occurred in 3 patients. 2) The radiologic findings were variable and nonspecific. Hilar calcification and parenchymal calcification were the most common findings. 3) The bronchoscopy was performed in 10 patients and revealed broncholiths in 9 patients. 4) Chemical composition of broncholiths was analyzed in 2 patients. Calcium carbonate was main component. 5) In 6 out of 9 patients in whom broncholiths was revealed by bronchoscopy, broncholiths were successfully extracted through the flexible bronchoscope. 6) In 9 patients, broncholithiasis was related to tuberculosis and in 1 case, related to silicosis. CONCLUSION: Broncholithiasis shows a variable clinical spectrum. Tuberculosis is the most common cause of broncholithiasis. In the case of no accompanied complication, nonsurgical management such as bronchoscopic removal and conservative therapy is an effective measure.

Purpose:
To identify the clinical usefulness of serum M protein and to establish a rationale for regular follow-up with serum protein electrophoresis in solitary plasmacytoma.
Materials and Methods:
Sixty-nine patients with solitary plasmacytoma and solitary plasmacytoma with minimal marrow involvement according to the International Myeloma Working Group criteria were retrospectively reviewed.
Results:
At a median follow-up of 6.2 years, 5-year local control (LC), 5-year multiple myeloma-free survival (MMFS), 5-year failure-free survival (FFS), and 5-year overall survival (OS) were 82.6%, 44.1%, 41.8%, and 85.1%, respectively. Among the patients whose initial serum M protein was present or not evaluated, 37.3% of patients showed disappearance of serum M protein after various treatment. MMFS of these patients were comparable to non-secretory plasmacytoma with undetectable levels of M protein, and significantly better than patients with persistent M protein. Increase of serum M protein ≥0.1 g/dL was most predictive of treatment failure with area under the curve of 0.731.
Conclusion
Patients who eventually showed persistence of serum M protein after treatment showed worse MMFS and FFS compared to those whose serum M protein disappeared or who had initially non-secretory disease. The increase of serum M protein level ≥0.1 g/dL from current nadir was predictive of treatment failure. Therefore, regular follow-up with serum M protein is highly recommended especially unless the patient had initially non-secretory disease.

OBJECTIVE: To analyze morphologic differences between only spondylolysis group and mild spondylolisthesis one in young-aged persons and to find useful parameters for radiological assessment of mild spondylolisthesis. METHOD: Twenty patients with only lumbar spondylolysis, 18 patients with mild lumbar spondylolisthesis and 19 normal subjects were recruited in this study. Their radiological findings were examined. The films of subjects were evaluated with respect to variables describing wedging of the spondylolytic vertebra, relative thickness and lengths of the transverse processes. The evaluation was made with attention to possible signs which could mean vertebral slipping. The lumbar index reflects the degree of wedge deformity of the spondylolytic vertebra. RESULTS: Lumbar index was significantly lower in spondylolisthesis group than only spondylolysis group. There was no significant difference in relative thickness of L5 transverse process between two groups. The incidence of a midline lumbar or sacral defect in the spondylolisthesis group was higher than other groups. CONCLUSION: Our results support the usefulness of lumbar index as a supplement parameter for radiological assessment of mild spondylolisthesis.

Percutaneous transhepatic biliary drainge (PTBD) is a widely accepted technique for the decotnn of biliary obstruction. However, PTBD is most frequently performed in patients whose prognosis is poor becauase of unresectable malignancy, sepsis, or advanced age. And this technique has disadvantages which inclusdes loss of biliary fluids, fat malabsorption, discomfort and psychologic problem for many patients. A 68-year-old man admitted to the hospital because of obstructive jaundice. He had received cholectystectomy two yeas ageo due to the perforation of gallbladder caused by adenocarcinoma of cystic duct. An external PTBD was placed. But because of the chronic bile loss, a percutaneous endoscopic gastrostomy (PEG) was inserted and drainge of bile into the stomach through an extracoporeal circuit utilizing the PTBD as an exit and PEG as an entrance was achieved.

BACKGROUD: Surgical resection is the treatment of choice for localized, operable non-small cell carcinoma of the lung. Curative radiotherapy, however, is considered an alternative to surgery in patients with poor performance state, poor cardiopulmonary function, or who refuse surgery. However, the difference in prognosis after surgery and radiotherapy is not well established in the patients with stage I non-small cell lung cancer. METHOD: To evaluate the difference in progonsis between surgery and radiotherapy in stage I non-small cell lung cancer, a retrospective study was done with 15 patients treated with curative radiotherapy and 24 patients treated with curative surgery. RESULTS: The overall response rate was 80%, with 33% complete response, after radiotherapy. The median survival time of the patients with radiotherapy was 14.9 months, with 2-year and 5-year survival rates of 22% and 0%, respectively. The median survival time of the patients with surgery was 37.7months, with 2-year and 5-year survival rates of 65% and 41%, respectively. CONCLUSION: These results suggest that surgery is better than the radiotherpy in view of survival rate and it is necessary to recommend, more strongly, curative surgery to patients with stage I non-small cell lung cancer if the patients are able to receive operation. To compare, more accurately, the difference in prognosis by the modality of therapy, large multicenter study is needed.

A number of genome-wide linkage analyses have identified the 2q33.3-2q37.2 region as most likely to contain the genes that contribute to the susceptibility to chronic obstructive pulmonary disease (COPD). It was hypothesized that the SERPINE2 gene, which is one of the genes located at the 2q33.3-2q37.2 region, may act as a low-penetrance susceptibility gene for COPD. To test this hypothesis, the association of four SERPINE2 single nucleotide polymorphisms (SNPs; rs16865421A>G, rs7583463A>C, rs729631C>G, and rs6734100C>G) with the risk of COPD was investigated in a case-control study of 311 COPD patients and 386 controls. The SNP rs16865421 was associated with a significantly decreased risk of COPD in a dominant model for the polymorphic allele (adjusted odds ratio [OR]=0.66, 95% confidence interval [CI]=0.45-0.97, P=0.03). In haplotype analysis, the GACC haplotype carrying the polymorphic allele at the rs16865421 was associated with a significantly decreased risk of COPD when compared to the AACC haplotype (adjusted OR=0.58, 95% CI=0.38-0.89, P=0.01), and this effect was evident in younger individuals (adjusted OR=0.30, 95% CI=0.14-0.64, P=0.002). This study suggests that the SERPINE2 gene contributes to the susceptibility to COPD.
