Objective To investigate the intracellular mechanisms by which 3,6-dihydroxyflavone inducing apoptosis of HL-60 cells.Methods After the HL-60 cells were treated with 3,6-dihydroxyflavone at the concentration of 5.10,20 or 40 mol/L,the cells then were inoculated under the selected optimal concentration.The survival rate of HL-60 cells was analyzed using a haemocytometer with standard trypan blue dye exclusion and a CASY cell counter and analyzer.The contents of malondialdehyde(MDA)and the activities of superoxide dismutase(SOD),catalase(CAT)and glutathione peroxidase(GSH-Px)in the cells were measured by chemochromatometry.The expression of phosphorylation of ERK,JNK and p38MAPK were examined by Western blotting.Results The survival rate of HL-60 cells was significantly reduced in a dose-and time-dependent manner after 3,6-dihydroxyflavone treatment.When the dose was over 10 mol/L or the time was longer than 12 h under the concentration of 20 mol/L,significantly decreased survival rate was observed(P

INTRODUTION: The purposes of this study was to examine physical function and psychological status in the elderly caused by a fall. METHOD: The study was designed as a descriptive survey. Its subjects consisted of the 299 elderly over 65 years. Collected data were analyzed by the SPSS 10.0 program package. RESULTS: The result of this study are as follows : 1) The score for ADL was significantly lower in the fall group. 2) Grip strength was significantly lower in the fall group. 3) Lapse of the motion sitting and standing was significantly longer in the fall group. 4) One-leg-standing time with the eyes open and closed was significantly shorter in the fall group. 5) Return time of 3m walk was significantly longer in the fall group. 6) The score for dizziness was significantly higher in the fall group. 7) The score for fear for a fall and depression were significantly higher in the fall group. 8) Thescore for falls efficacy was significantly lower in the fall group. CONCLUSION: ADL, muscle strength, balance, dizziness, fear for a fall, falls efficacy and depression turned out to be closely related to the fall of the elderly. Therefore, it would be required to develop and applicate the fall prevention program regarding these above risk factors.

We report metastatic omental hepatocellular carcinoma in two patients with post-lobectomy hepatocellular carcinoma who have had previous abdominal surgery or the rupture of hepatocellular carcinoma. Ometal metastatic masses were similar to primary masses of the liver in pathologic findings as well as in radiologic findings.

Magnetic resonance (MR) is rapidly emerging technique that provides high quality images and potentially provides much more diagnostic information than do conventional imaging modalities. MRI is conceptually quite different from currently used imaging methods. The complex nature of MRI allows a great deal of flexibility in image production and available information, and key points are as follows. 1. MR offers a non-invasive technique with which to generate in vivo human images without ionizing radiation and with no known adverse biological effects. 2. Imaging mechanism of MRI is quite different from conventional imaging modality and for more accurate diagnostic application, It is necessary for physician to understand imaging mechanism of MRI 3. M.R. makes available basic chemical parameters that may provide to be useful for diagnostic medical imaging and more specific pathophysiologic information which are not available by alternate techniques. 4. M.R. can be produced by number of different methods. This flexibility allows the imaging technique to be applicated for particular clinical purpose. Multiplanar and three dimensional imaging may extend the imaging process beyond the single section available with current CT. 5. Future directions include efforts to; a. Further development of hard ware b. More fastening scan time c. Respiratory and cardiac gated imaging d. Imaging of additional nuclei except hydrogen. e. Further development of contrast media f. MR in vivo spectroscopy g. Real time MR imaging

Takayasu's arteritis is an arteritis of undetermined etiology, which affects the aorta, proximal portion of its major branches, and causes narrowing, occlusion, or aneurismal dilatation of vessel. Authors report 2 cases of Takayasu's arteritis with brief review of the literature.

A case of foregut cyst communicated with esophagus and lined by bronchial mucosa is reviewed and its embryologic base of maldevelopment it discussed. It is not always easy to distinguish between digestive and respiratory cyst in mediastinum. There is whole range of intermediate between a cyst with ciliated and one with squamous or columnar mucosa. Origin of this dysembryoplasia is difficult to determine when on consider that the esophagus is covered with ciliated epithelium until the eleventh week of fetal life and that ciliated growth are found on its wall until the sixth month of the fetal life. And we concluded, general agreement is that cysts which have gastric epithelium in whole or in part, represent a distinct type and should be classified as (gastro) enteric cyst, mediastinal cyst containing cartilage were considered definitely as respiratory (bronchial or bronchogenic) cyst.
