BACKGROUND: Methicillin-resistant Staphylococcus aureus (MRSA) is hardly controllable organism among the pathogen of nosocomial infection, because it is resistant to most antibiotics except vancomycin and local treatment with most antiseptics are not effective to eradicate MRSA from the infected wounds. There is increasing fear that MRSA infection can be spread widely in the hospitals. The effectiveness of Gentian Violet against MRSA was reported by Saji et al in 1992 for the first time. We tried Gentian Violet dressing on MRSA infected wounds to evaluate whether at not the Gentian Violet is effective to eradicate 11RSA which existed in the open wound. METHODS: 24 patients were treated by wet dressing with 0.1%Gentian Violet soaked gauze twice daily. They included 10 cases of sacral and trochanteric pressure sore, 6 cases of postoperative wound infectious, 3 cases of posttraumatic skin defects, 2 cases of DM foot, 1 case of post infectious skin defect and 2 cases of electrical burn, The wound culture was evaluated for elimination of MRSA infection twice weekly. RESULTS: The clinical results revealed that MRSA was not detected in all cases within 34days (average 13.5 days) after topical administration 0.1% Gentian Violet. CONCLUSION: There is no evidence of tissue irritation with Gentian Violet dressing on open wound or wound margin. After negative conversion of MRSA with Gentian Violet dressing, gram (-) organism was isolated in a half of the cases. 0.1% Gentian Violet topical administration is a useful treatment method of wound infection with MRSA.

There are 3 basic methods for surgical treatment of axillary osmidrosis; 1) method that removes only subcutaneous cellular tissue without removing skin 2) method that removes skin and subcutaneous cellular tissue en bloc, and 3) method that partially removes skin and subcutaneous cellular en bloc as well as removing the subcutaneous cellular tissue of the adjacent region. We studied the results of partial removal of the skin and subcutaneous cellular tissue en bloc, as well as the removal of subcutaneous cellular tissue of the adjacent region to compare the results of the bipedicled flap with the graft conversion method. There was no difference between two methods in results and complication rates. There are 3 advantage to this procedure. First, about 70-80% of apocrine glands were centrally distributed among the axillary hairbearing region therefore, resection of the central portion of axillary hair distribution area is important for good result. Second, the preservation of the subdermal plexus with careful excision of adjacent underlying subcutaneous tissue under the aid of the magnifying surgical loupe, is important for good wound healing. Third, the central excision of the axillary hair distribution area provides good exploration for undermining and defatting of the undersurface of the adjacent area, therefore it tooks a shorter operation time.

Mandible fractures have recently been managed by rigid internal fixation with miniplate and screws more often than by traditional interosseous wiring methods. The purpose of this paper was to compare traditional interosseous wiring with miniplate fixation in open reduction of mandible fracture, especKweonially in operative results and costs. From June of 1989 to June of 1998, there were 142 patients, admitted to the department of Plastic and Reconstructive Surgery, Chun-Cheon Sacred Heart Hospital, Hallym University. Of those, 101 patients were managed by open reduction, and among them, 83 patients were treated with miniplate fixation, but 18 patients had recently been treated with interosseous wiring methods. No significant difference was noted between the two groups in terms of complications, but the overall cost of miniplate and screws was higher than interosseous wiring, while the mean operative time was longer in the group treated with miniplate fiation. The authors recommend interosseous wiring technique for patients with mandible fractures requiring open reduction and fixation, except for absolute indications of rigid internal fixation.

BACKGROUND: Left ventricular function and left ventricular hypertrophy often show weak correlation with the degree of blood pressure in hypertensive patients. So we assessed correlation of hemodynamic load to left ventricular hypertrophy and left ventricular performance, and whether left ventricular wall stress is the major factor on the regulation of left ventricular function. METHODS: Relationships between echocardiographic hemodynamic parameters and indices of left ventricular hypertrophy and left ventricular function were evaluated in 40 patients with essential hypertension who have not been previously treated. RESULTS: Left ventricular mass index correlated weakly with blood pressure, cardiac index, and stroke volume. End-diastolic left ventricular relative wall thickness, as an index that assess the severity of concentric hypertrophy showed significantly negative correlation with cardiac index (r=-0.49, p<0.001),stroke index(r=-0.46, p<0.001) and a positive correlation with total peripheral resistance (r=0.55, p<0.001). Furthermore, patient with cardiac indices tend to have higher end-diastolic wall thickness at any given level of blood pressure. Fractional shortening suggesting left ventricular systolic function was not related with blood pressure. stroke volume, cardiac index, left ventricular mass index, and peak systolic wall stress. In contrast there were significant negative correlations between fractional shortening with mean wall stress index (r=-0.42, p<0.005) and with end-systolic wall stress (r=-0.72, p<0.001). CONCLUSIONS: These results suggest that anatomic and hemodynamic changes may be pathophysiologically interdependent and left ventricular function was regulated by the level of left ventricular wall stresses reflecting afterload (blood pressure).

Betulinic acid (BA), a natural pentacyclic triterpene found in many medicinal plants is known to have various biological activity including tumor suppression and anti-inflammatory effects. In this study, the cell-death induction effect of BA was investigated in BV-2 microglia cells. BA was cytotoxic to BV-2 cells with IC50 of approximately 2.0 μM. Treatment of BA resulted in a dose-dependent chromosomal DNA degradation, suggesting that these cells underwent apoptosis. Flow cytometric analysis further confirmed that BA-treated BV-2 cells showed hypodiploid DNA content. BA treatment triggered apoptosis by decreasing Bcl-2 levels, activation of capase-3 protease and cleavage of PARP. In addition, BA treatment induced the accumulation of p62 and the increase in conversion of LC3-I to LC3-II, which are important autophagic flux monitoring markers. The increase in LC3-II indicates that BA treatment induced autophagosome formation, however, accumulation of p62 represents that the downstream autophagy pathway is blocked. It is demonstrated that BA induced cell death of BV-2 cells by inducing apoptosis and inhibiting autophagic flux. These data may provide important new information towards understanding the mechanisms by which BA induce cell death in microglia BV-2 cells.
