Periosteal osteosarcoma is a distinct entity of malignant bone tumor with characteristic clinical, morphological, and histological features within the group of juxtacortical osteosarcoma. Periosteal osteosarcoma is predominantly located in the tubular long bones, and extremely rarely involving the jaws. A case of periosteal osteosarcoma of the right mandible is presented. A 27-year-old woman complained of the gingival swelling and bleeding tendency of the right posterior mandible. Clinical examination revealed a reddish brown strawberry-like swelling on the affected mucosa, which measured 1.5㎝×1.5㎝. The tumor was located on the lingual cortex of the mandible and extended into the surrounding soft tissues. Microscopically, the tumor consisted exclusively of atypical chondroblastic cells with a small osteoblastic area. A minimal bone marrow involvement was noted and the adjacent cortex was free of tumor. These findings suggested that the tumor originated from the periosteal cambium layer, which lies between the periosteal fibrous layer and the cortex of mandible.

Purpose: We investigated whether the calbindin-D_(28K) (CB) immunoreactivity could be available as a neurochemical marker to identify different anatomical subdivisions in the midbrain periaqueductal gray (PAG) of laboratory animals. Materials and Methods: Immunohistochemistry for CB and histochemistry for cytochrome oxidase (CO) were carried out on coronally-sectioned midbrain slices of five species of animals including mice, hamsters, rats, rabbits and guinea pigs. Results: In the rat PAG, at the level of nucleus of trochlear nerve, CB immunoreactive perikarya and plexus of fibers were localized in three band-like areas including dorsolateral PAG (DL), the ventral part of lateral PAG (Lv) and the supraoculomotor cap nucleus (Su3C). The similar pattern in the distribution of CB immunoreactivity was noticed also in the rabbit and the guinea pig PAG at the corresponding level, with three areas of DL, Lv and the ventral part of ventrolateral PAG. In all the 5 species of animals, Su3C was readily marked with clusters of CB-immunoreactive perikarya and fibers. In the comparison between the CB-immunoreactivity and the CO activity in the PAG, CB-immunoreactive areas were coincidided with areas of the low CO activity. Conclusion: The present data suggest that the CB immunoreactivity can be regarded as a reliable neurochemical marker for the specific areas within the midbrain PAG.

Background and objectives: Many conditions are responsible for the pathophysiology and progressive mechanisms of congestive heart failure. More recently, it has also become evidence that another class of biologycally activated molecules generically reffered to as cytokine these are also over expressed in congestive heart failure. Therefore, the purpose of this study was to measure concentrations of tumor necrosis factor-α(TNF-α), interleukin-6(IL-6) in mild to severe symptoms of heart failure and compare their values with those found in normal control and analysed correlation relationship between cytokine level, clinical findings and hemodynamic indicies. Subjects and Methodology: Levels of TNF-α and IL-6 were measured on pulmonary artery during cardiac catheterization in heart failure patients(n=32) and normal subjects(n=8) as well as physical examination and echocardiogram. Cytokines assay were performed on plasma using commercially available ELISA(Enazyme-Linked Immunosorbent Assay) kits. Results: Although the levels of TNF-α and IL-6 tend to increase in congestive heart failure group, the cytokines level was not made significantly statistical difference between congestive heart failure group and controls. When analyzing the correlation between the levels of PCWP(pulmonary capillary wedge pressure) and cytokines(TNF-α, IL-6), respectively, there were statistically significant correlation coefficient 0.32,(p<0.05), 0.39(p<0.01). The cytokine IL-6 and pressure of pulmonary artery were significant correlation.(correlation coefficient 0.36, p<0.02) More significantly, there was correlated with TNF-α and IL-6.(correlation coefficient 0.57, p<0.001) Conclusions: There was tended toward high concentration of TNF-α & IL-6 in congestive heart failure and significant difference for PCWP between TNF-α & IL-6, thus may be correlated with development and progression in congestive heart failure.

The influence of single and repeated oral pretreatment of CHUNG-HYUL-DAN(CHD). a widely used Korean traditional herbal medicines prescribed for hypertension and hyperlipidemia, on the pharmacokinetics and pharmacodynamics of a calcium channel blocker, nicardipine after oral administration of nicardipine was investigated in rats. The single pretreatment of CHD significantly increased area under the plasma concentration-time curve(AUC_(0-8h), but did not influence the time to reach the maximum peak plasma concentration(T_(max)), the maximum peak plasma concentration(C_(max)), terminal elimination half-life(t_(1/2) or the elimination rate constant(λ) for nicardipine. And, C_(max) and AUC_(0-8h) for nicardipine were significantly increased by with 1-week repeated pretreatment with CHD, but the other parameters were not significantly different from those of control. Also, the extent of the lowering effect of nicardipine on blood pressure in rats was significantly increased after oral administration of nicardipine with single and repeated oral pretreatment with CHD. These results indicated that single and 1-week repeated oral pretreatment with CHD should inhibit the metabolism of nicardipine in rats.

Objectives : This study was designed for the evaluation of relationships between PC-Bang (the place where people surf the internet, play computer games and etc) visit and stress in adolescents. Methods : 66 adolescents in city of Kangnung were interviewed in June, 2000. The independent variables were general characteristics of adolescents, the characteristics related to school activities and the length of time using PC-Bang. The amount of stress was measured by the Korean version BEPSI (Brief Encounter Psychosocial Instrument) scale. Results : The multiple regression analysis shows that the BEPSI score of female was higher than that of male by 0.18 (p<0.05) and the adolescents with more communication with their friends scored lower 4.04 (p<0.001) than others in the BEPSI. As the time used in PC bang increased, the BEPSI score was also increased 0.18 point per hour (p<0.01). Conclusion : This result shows that the time of PC-Bang usage is significantly related with the BEPSI score of adolescents.

Study Design : Spine fusion with fixation procedure is associated with substantial operative blood loss, which frequently necessitates transfusion. The authors evaluated the safety and efficacy of intraoperative autotransfusion using Cell Saver during spinal surgery. Summary of Literature Review : It has been reported that the contraindications to the use of intraoperative autologous transfusion are malignancy, infection, and gross wound contamination. Objectives : The purpose of this study was to evaluate the safety and efficacy of intraoperative autotransfusion using Cell Saver during spine surgery. Material and Methods : We retrospectively reviewed 62 patients who had operation for lumbosacral spinal stenosis and hypotensive anesthesia. Among them, Group Ⅰwhich received autotrans fusion using Cell Savers included 26 patients with fusion of 2 segments, and Group Ⅱ as control group included 13 patients. Group Ⅲ which received autotransfusion using Cell Savers included 17 patients with function of 3 segments, and Group Ⅳ as control group included 6 patients. We analyzed the amount of intraoperative blood salvage using a Cell Saver, the amount of total homologous transfusion amount, intraoperative blood loss, the amount of postoperative drainage amount and perioperative changes of hemoglobin, hematocrit and platelet count. Results : There was no statistical significance between Cell-Saver group and control group in amount of total homologous transfusion and intraoperative(except in 2 segment of fusion using cell saver: 86.5% increased) & postoperative blood loss(p>0.05). The circulatory balance(amount of intraoperative blood salvage using a Cell Saver plus amount of total homologous transfusion minus amount of total blood loss) was statistical significance between Cell-Saver group and Control group. The Cell-Saver group had positive balance and Control group had negative balance. There were no statistical differance in the evolusion of hemoglobin, hematoocrit and platelet count between Cell-Saver group and Control group(p>0.05). There was no transfusion reaction and thromboembolic disease in all group. Conclusion : In retrospective study, Cell Savers was safe and immediate availability in orthopedic surgery such as spinal surgery. It was effective methods for storing a sufficient volume of blood for spine surgery without affecting the patient's postoperative hemodynamic ststes, too. It was possible to operation without intraoperative homologous blood transfusion in 2 or 3 segment fusion. We may need further study.
