BACKGROUND: The valve area derived from the Gorlin formula has been used clinically for decades as an index of severity on the assessiment of valve stenosis, in spite of some limitations on Gorlin formula studied in aortic stenosis and mitral bioprostheses. It had been shown that Gorlin valve area varied if the hemodynamic conditions during measurement are changed. Valve resistance has been proposed as an alternative hemodynamic indicator, but initially this index was not used because it was unlikely to remain constant at different flow rates. Recently valve resistance provided a better indices of hemodynamic obstruction than mitral valve area, and these stenotic indices usually estimated by angiographic method and we studied the valve resistance by Doppler echocardiographic measurement. METHOD AND RESULT: To compare the clinical implication about these stenotic indices measured by echcoardiography and cardiac catheterization, we studied 41 patients of mitral stenosis with normal sinus rhythm. The results were as follows ; 1) In catheterization, increased heart rate, mean pressure gradient and decreased diastolic time was observed, but mitral area, resistance, cardiac output and mitral flow was not different. 2) Linear regression analysis showed negative correlation of mitral valve resistance and Gorlin mitral area(echocardiography r=-0.84, catheterization r=-0.84)(p<0.001). 3) Correlation coefficeint of mitral valve area and mitral valve resistance between echocardiography(r=0.87) and catheterization(r=0.82) showed positive correlation(p<0.001). CONCLUSION: These results suggest that mitral valve resistance by echocardiography is a useful method in the evaluation of the severity of mitral stenosis.

Scar endometriosis is one of the rare conditions among the extrapelvic endometriosis, but it often occurs after pelvic operation and episiotomy. Four cases of scar endometriosis following Cesarean section and episiotomy were exp- erienced and treated with complete surgical excision. Therefore we reported these cases with concerned literatures.

A 69-year-old man was admitted to our hospital for deep vein thrombosis, and he had experienced two episodes of left leg swelling: one happened after an 11 hour-air trip from Europe in June 2007, and the other developed 3 days after an operation for a herniated lumbar disc in July 2007. We treated him for a deep vein thrombosis of the deep femoral vein after admission. However, we arrived at the final diagnosis of angioleiomyosarcoma after the operation for the tentative diagnosis of deep vein thrombosis. We removed the firmly engorged deep femoral vein on the second operation. We report here on a case of angioleiomyosarcoma that arose from the deep femoral vein.

We evaluated the biological scaffold properties of canine small intestinal submucosa (SIS) compared to a those of polypropylene mesh in growing rats with full-thickness abdominal defects. SIS is used to repair musculoskeletal tissue while promoting cell migration and supporting tissue regeneration. Polypropylene mesh is a non-resorbable synthetic material that can endure mechanical tension. Canine SIS was obtained from donor German shepherds, and its porous collagen fiber structure was identified using scanning electron microscopy (SEM). A 2.50-cm2 section of canine SIS (SIS group) or mesh (mesh group) was implanted in Sprague-Dawley rats. At 1, 2, 4, 12, and 24 weeks after surgery, the implants were histopathologically examined and tensile load was tested. One month after surgery, CD68+ macrophage numbers in the SIS group were increased, but the number of CD8+ T cells in this group declined more rapidly than that in rats treated with the mesh. In the SIS group, few adhesions and well-developed autologous abdominal muscle infiltration into the SIS collagen fibers were observed. No significant differences in the tensile load test results were found between the SIS and mesh groups at 24 weeks. Canine SIS may therefore be a suitable replacement for artificial biological scaffolds in small animals.

In the present study, we performed immunohistochemical studies to investigate the detailed distribution of insulin-like growth factor binding protein 7 (IGFBP7) in the central nervous system of adult rats. Twelve adult (4~6 month old) Sprague-Dawley rats were examined in this study. Immunohistochemistry using specific antibodies against IGFBP7 was performed in accordance with the free-floating method. In the present study, IGFBP7 immunoreactivity was observed in the cerebral cortex, hippocampus, brainstem, cerebellum and spinal cord. In the cerebral cortex, heavily stained neurons were seen in layers II-VI. In the hippocampus, pyramidal cells in CA1-3 region were strongly immunoreactive for IGFBP7. Strong immunoreactive neurons were also found in the supraoptic nucleus, paraventricular nucleus, periaqueductal gray and oculomotor nucleus. In the cerebellum, IGFBP7 immunoreactivity was prominent in the Purkinje cells and cerebellar output neurons. IGFBP7-immunoreactive neurons were prominent in the superior vestibular nucleus, cochlear nucleus, trigeminal motor nucleus, nucleus of the trapezoid, and facial nucleus. IGFBP7-immunoreactive neurons were also observed mainly in the anterior horn of the spinal cord. The first demonstration of IGFBP7 localization in the whole brain may provide useful data for the future investigations on the structural and functional properties of IGFBP7.

This study was carried out to evaluated the actual conditions of working environment and health status of workers and search more effective health management method of workers in some dyeing factories. This study was conducted from April 1 to October 30, 1992, for 426 workers in two dyeing factories and an electric wire making factories. Among 324 workers in two dyeing factories, 57.5% were male and 42.5% were female. Most of the engaged workers had less than 2 years of working carrier and aged 30 years or below. The used chemical substances exceeding 1 ton per a month were sodium hydroxide(NaOH), hydrogen peroxide(H2O2), sodium chlorite(NaClO2), sodium sulfate(Ma2SO4), sodium carbonate(Na2CO3), and sodium hydrosulfite(Na2S2O4). The used chemical dyes exceeding 100kg per a month were suncion blue H-ERD, levafix brilliant red E-4BA, suncion yellow E-3G, and remazol black B. As the allowable exposure time by governmental threshold limit valuses to industrial noise levels in 90 dBA for 8 hours. Average noise levels of the individual plants were ranged from 75 to 95 dB (A). The TLV for total cotton dust in 2.0mg/m3. Average cotton-dust concentration in these working environmental air were ranging from 0.2-1.3mg/m3. The TLV chlorine, acetic acid and formic acid are 1 ppm, 10 ppm & 5ppm, respectively. The range of chlorine, and acetic and formic acid concentration in these working environmental air were detected 0.2-1.6 ppm and at trace level. The accident by chemical substances and dyes was not found on these working environment. From the physical examination and Todai Health Index scores results, there was no significant correlation between the used chemical substances and the diseases, such as bronchial asthma, other hyperreactive respiratory diseases and contact dermatitis. It was suggested that long term survey should be performed to detect the occupational health problem on these working environment.

Here, percutaneous spinal cord injury (SCI) methods using a balloon catheter in adult rats are described. A balloon catheter was inserted into the epidural space through the lumbosacral junction and then inflated between T9-T10 for 10min under fluoroscopic guidance. Animals were divided into three groups with respect to inflation volume: 20 microL (n = 18), 50 microL (n = 18) and control (Fogarty catheter inserted but not inflated; n = 10). Neurological assessments were then made based on BBB score, magnetic resonance imaging and histopathology. Both inflation volumes produced complete paralysis. Gradual recovery of motor function occurred when 20 microL was used, but not after 50 microL was applied. In the 50 microL group, all gray and white matter was lost from the center of the lesion. In addition, supramaximal damage was noted, which likely prevented spontaneous recovery. This percutaneous spinal cord compression injury model is simple, rapid with high reproducibility and the potential to serve as a useful tool for investigation of pathophysiology and possible protective treatments of SCI in vivo.

We induced percutaneous spinal cord injuries (SCI) using a balloon catheter in 45 rats and transplanted human umbilical cord blood derived mesenchymal stem cells (hUCB-MSCs) at the injury site. Locomotor function was significantly improved in hUCB-MSCs transplanted groups. Quantitative ELISA of extract from entire injured spinal cord showed increased expression of brain-derived neurotrophic factor (BDNF), nerve growth factor (NGF) and neurotrophin-3 (NT-3). Our results show that treatment of SCI with hUCB-MSCs can improve locomotor functions, and suggest that increased levels of BDNF, NGF and NT-3 in the injured spinal cord were the main therapeutic effect.

Most foreign bodies in the lower genitourinary tract are self-inserted via the urethra as the result of exotic impulses, psychometric problems, sexual curiosity, or sexual practice while intoxicated. Diagnosis of these foreign bodies can be done by clinical history, physical examination, and image studies of the patient. The treatment of foreign bodies is determined by their size, location, shape, and mobility. In most cases, minimally invasive procedures such as endoscopic removal are recommended to prevent bladder and urethral injuries. In some cases, however, surgical treatment should be done if the foreign bodies cannot be removed by the endoscopic procedure or further injuries are expected as a result of the endoscopic procedures. Herein we present 2 cases of self-inserted lower genitourinary foreign bodies with a brief review of the literature.
