Retroperitoneum is often the site of occurrence of schwannoma, but reports on schwanoma of the adrenal gland is exceptional and only 4 cases have been documented in the literature. This report is to add one such case occurred in a 53 year-old male who had anorexia, nausea and indigestion for one month. Whole body bone scan and abdominal CT scan revealed a 10 cm sized solid mass at upper pole of the left kidney. Under the impression of renal cell carcinoma, an operation was performed. The tumor was well encapsulated and appeared not to involve the kidney. The cut surfaces were light yellow and seemed to be composed of several hard lobules with areas of mucoid, cystic and calcific changes. No adrenal gland was identified grossly. But microscopically, the tumor was found to be partly surrounded by a small portion of adrenal cortical tissue. Histologically the tumor was a typical schwannoma with Verocay bodies, although modified in some extents by mucoid degeneration, cystic change, hyaline change and focal calcification. It is worthwhile to remember that the retroperitoneal schwannoma commonly had a huge size, sometimes involving the adjacent structures.

Leiomyomatosis peritonealis disseminata is a rare benign condition characterised by the occurrence of multiple leimyomas scatterred throughout the peritoneal cavity, giving the clinical impression of a wide spread malignant tumor. The histopathology of leiomyomatosis peritonealis disseminata is that of a benign leiomyoma, probably originating from the multipotent subcoelomic mesenchymal cells. Three cases with malignant transformation were described among previous reported fifty cases. Many of the early reports described the disorder in premenopausal women, and now the histogenesis is considered to be a metaplastic change by abnormal tissue response to the relatively or absolutely elevated female sex hormone. We report a case of leiomyomatosis peritonealis disseminata, which was diagnosed by multiple scattered submucosal and subseroal leimyomas of stomach, small bowel and colon, combined with advanced gastric cancer in a 58 years old man, Multiple submucosal tumors of the stomach combined with advanced gastric cancer were demonstrated by fibergastroscopy, upper gastrointestinal barium study and abdominal ultrasonography. During radical subtotal gastrectomy multiple submucosal and subserosal tumors of stomach, and subserosal tumors of small bowel and colon were observed and these tumors were confirmed as leiomyoma without malignant potential.

Objective: To investigate the syndrome property of myocardial Ischemic, and evaluate the relevant informations of qi-deficiency. Methods: SD rats were subjected to either proximal LAD ligation or sham operation. The respiratory rate in both resting state and post-stress were counted. 20 rats (10 in each group) were subjected to forced swimming test (FST) to measure the exhaustive swimming time in every time point Echocardiography was used to evaluate the cardiac function in rats at each time point. Results: Compared with sham operation group, the respiratory rate in the resting state was slower, but faster under post-stress, the exhaustive swimming time was shorter, and the cardiac function of rats was significant decreasing in model group during the period from 7th day to 60th day after operation. The exhaustive swimming time was much shorter, and the relevant information of blood stasis was abnormal in the model group during the period from 7th day to 28th day after operation, when compared with the sham group. Conclusion: Myocardial ischemic rats induced by LAD ligation had both qi-deficiency and blood stasis indications, can be diagnosed as the syndrome of qi-deficiency and blood stasis during the period from 7th day to 28th day after operation. The model rats only had the qi-deficiency indications during the period from 45th day to 60th day after operation, so can be diagnosed as the qi-deficiency syndrome.

The application of stereotactic techniques and endoscopy dates back to the beginning of this century and is almost as old as neurosurgery itself. However, endoscopic techniques progressed slowly for several reasons. A reappraisal of endoscopic techniques become popular about 1985. The major indication of endoscope in neurosurgical field is intraventricular procedures. Recently it can be used selectively in the intraaxial mass lesion associated cavity. For example, cystic mass, with liquefied necrosis, blood clot can be approached with endoscope. Authors present its intraaxial application in basal ganglionic hematoma in three patients. Conventional stereotactic guidance of neuroendoscope was done and the hematoma was gently removed through continuous irrigation and suction under video-guidance. The clinical course was uneventful. Brief overview is given of this intraaxial neuroendoscopic procedure.

OBJECTIVES: To estimate the prevalence of hypertension, rates of awareness, treatment modalities, and control of hypertension, and also to identify factors in rural Korea that are related to these aspects of hypertension. METHODS: A cross-sectional survey, including blood pressure(BP) measurements and interviews, investigating the variables in the health belief model was performed from August to November, 1999 on 1,426 (79.4%) study subjects out of 1,797 registered residents over 30 years old in Ibansong-Myun, Chinju City. A second survey was performed from January to March, 2000 on 376 (80.0%) subjects out of 470 hypertensive (or suspected hypertensive) subjects found in the first survey. Two BP readings were taken in each survey using a standard mercury sphygmomanometer. Hypertension was defined as either a BP reading < 140/90 mmHg in both surveys, or as subjects on oral hypertensive medication. RESULTS: Estimated hypertension prevalence was 24.9% for men, and 30.4% for women. Rates of hypertension awareness, treatment (the regular use of oral hypertensives), and control (reduction of BP to <140/90 mmHg) were 52.5%, 34.4%, and 12.9%, respectively. The factors related to lower hypertension awareness in the logistic regression analysis were male gender, farming occupation, and higher perceived barrier to medical treatment (those for whom visiting health professionals is a burden). CONCLUSIONS: To improve the low awareness, treatment, and control of hypertension, a more active and out-reaching hypertension control program, including routine BP measurements for every visitor to primary care facilities, is needed in rural Korea.

Sebaceous epithelioma is a rare skin appendage tumor with sebaceous differentiation. It may occur as a primary lesion or may arise within a nevus sebaceus. We present two cases of sebaceous epithelioma developed on the scalp in a 55-year old woman and on the forehead in a 75-year old wornan. Histopathologically the tumors are composed of irregularly shaped cell masses. The majority of cells are undifferentiated basaloid cells, but some cells show differentiation toward sebaceous cells.

The purpose of present study was to observe the radiographic finding and histologic response by Confocal Laser Scanning Microscopy(CLSM) on interface of the bone and titanium implant coated by chitosan. The tissue of rabbit tibiae to the surgical placement titanium implant coated by chitosan was examined at 3, 9 and 24 days postoperatively. The radiographic finding showed that surrounding bone density of implants was not significantly different compare with the bone on 3 and 9 days group. A large amount new bone was formed on 24 days group, the reason was osteconduction activity by chitosan. The CLSM analysis show that the surface coating by chitosan filled the gap between bone and implant on 3 days group and filled by mew born on 9 days group. On 24 days group, the bone and titanium surface was filled by lamella bone. This results indicated that this enhanced the initial stability of implant significantly and chitosan induced osseointegration around implant. CLSM allows the non-destrutive histo-tomography of bone biopsy as well as clinical practice. We conclude that CLSM allowed a good comprehension of the nature of bone-implant contact, avoiding artifacts due to the thickness of the specimen.
