BACKGROUND: It is known that QT dispersion represents asynchronous repolarization of ventricle which is related to ventricular fibrillation. The incidence of ventricular arrhythmia is increased after acute myocardial infarction. So this study compared QT dispersion and other repolarization indexes for detection of asynchronous repolarization in acute myocardial infarction. We also investigated which portion of repolarization is the key portion of the asynchrony. METHODS: In 37 acute myocardial infarction patients and 38 angina patients dispersion of QT, JT, JTpeak and QTpeak were measured. We also measured maximum adjacent dispersion of same parameters in precordial leads. In 20 survived patients and 17 dead patients after acute myocardial infarction were also compared. We also investigated correlation of PVC's on Holter monitoring with these repolarization parameters. RESULTS: 1) All ventricular repolarization indexes(QT, QTc, JT, JTpeak, QT peak and TpeakTend dispersion) were significantly increased in acute myocardial infarction group than compared with those of angina group(p<0.05). 2) Maximal precordial dispersion(QT, QTc, JT, JTpeak and QTpeak) were also significantly increased in acute myocardial infarction group than angina group(p<0.05). 3) Dead patient group after myocardial infarction showed significantly increased QTc and TpeskTend dispersion compared with those of survived patient group(p<0.05). 4) Multivariate linear correlation showed that TpeakTend dispersion and JT dispersion was correlated with QT dispersion. CONCLUSIONS: There were asynchronous myocardial repolarization changes in acute myocardial infarction. Our study demonstrated that T wave change was major determinant of dispersion of myocardial repolarization.

Acquired hemophilia A (AHA) is a rare disease where typically coagulation factor VIII is inhibited by autoantibodies. It occurs in patients with no personal or familial history of bleeding. In this case study a 61-year-old male presented with a huge psoas hematoma. He had no history of bleeding disorders. He was initially diagnosed with delayed traumatic hematoma. Despite conservative and surgical treatments, coagulopathy was not resolved and postoperative bleeding continued. Consequently, coagulation factor tests were performed and showed reduced activity of factor VIII (2.7%). In addition, factor VIII inhibitor was detected. The patient was diagnosed with AHA and administered recombinant factor VIII for 3 days which resulted in the cessation of bleeding. AHA can lead to a life-threatening hemorrhage, and needs to be considered in differential diagnoses in any patients presenting with unexplained and repeated bleeding, where there is no personal or familial history of bleeding disorders.

PURPOSE:To describe the features of displaced bucket-handle tears of the menisci on magnetic resonance (MR) images and to assess associated knee injuries. MATERIALS AND METHODS: We retrospectively reviewed coronal and sagittal MR images in 21 bucket-handle tears. The subjects were patients who had underwent preoperative MR evaluations of the knee and were identified from the arthroscopic surgical records as bucket-handle tear. We also described patterns of associated injuries. RESULTS:On coronal MR images, (a) in all cases, peripheral portion of the meniscus(bucket) had the appearance of a truncated or altered wedge;(b) central fragments(handle) were observed to be sitting in the intercondylar notch(16 cases) or located between the fernoral condyle and tibial plateau (5 cases). On sequential sagittal MR images, (c) the bow-tie appearance of the body of the meniscus was not seen (13 cases);(d) the bow-tie appearance of the displaced inner fragment was seen at the intercondylar notch level (9 cases);(e) "double posterior cruciate ligament" sign was presented (7 cases). Associated joint abnormalities included anterior cruciate ligament tears(l 1), contralateral meniscal tears(l 1), posterior cruciate ligament tears(3), medial collateral ligament tears(3), osteoarthritis(1), and Baker's cyst(l). CONCLUSION:Awareness of these characteristic MR findings(a-e) may increase the sensitivity of MR imaging in the diagnosis of displaced bucket-handle tears, and the MRI may be helpful to correctly characterize the displaced fragment and patterns of associated injury, providing arthroscopists a guide to appropriate surgical plans.

7.Acetaminophen Induced Cytotoxicity and Altered Gene Expression in Cultured Cardiomyocytes of H9C2 Cells.
Environmental Health and Toxicology 2012;27(1):e2012011-
OBJECTIVES: Hepatotoxicity of acetaminophen has been widely studied. However, the adverse effects on the heart have not been sufficiently evaluated. This study was performed to investigate cytotoxicity and alterations of gene expression in cultured cardiomyocytes (H9C2 cells) after exposure to acetaminophen. METHODS: H9C2 cells were incubated in a 10 mM concentration of acetaminophen for the designated times (6, 12, and 24 hours), and cytotoxicity was determined by the 3-(4, 5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide method. Alteration of gene expression was observed by microarray analysis, and RT-PCR was performed for the three representative oxidative stress-related genes at 24 hours after treatment. RESULTS: It revealed that acetaminophen was toxic to cardiomyocytes, and numerous critical genes were affected. Induced genes included those associated with oxidative stress, DNA damage, and apoptosis. Repressed genes included those associated with cell proliferation, myocardial contraction, and cell shape control. CONCLUSIONS: These findings provide the evidences of acetaminophen-induced cytotoxicity and changes in gene expression in cultured cardiomyocytes of H9C2 cells.

The lack of sufficient oral mucosa available for intra-oral reconstruction has been dealt with by the use of skin or oral mucosa grafts harvested from donor sites but grafts requires more than one surgical procedures and could cause donor site morbidity. Many investigators have attempted to increase available soft tissue by tissue engineered skin or oral mucosa replacements for clinical applications. But, reconstructed mucosa by several methods have low physical properties such as rolling and contraction. The aims of this study were to develope an in vitro experimental model that maintains an epithelial-mesenchymal interaction by organotypic raft culture, and to characterize biologic properties of three-dimensionally cultured oral mucosa embedded with Polydioxanone mesh by histological and immunohistochemical analysis. The results were as follows; 1. Oral mucosa reconstructed by three-dimensional organotypic culture revealed similar morphologic characteristics to equvalent normal oral mucosa in the point that they show stratification and differentiation. 2. The expression of cytokeratin 10/13 and involucrin in the cultured tissue showed the same pattern with normal oral mucosa suggesting that organotypic co-culture condition is able to induce cellular differentiation. 3. After insertion of polydioxanone mesh, increased tensile strength were observed. These results suggest that three-dimensional organotypic co-culture of the oral mucosa cell lines with the dermal equvalent consisting type I collagen and fibroblasts reproduce the morphologic and immunohistochemical characteristics similar to those in vivo condition. And increased physical properties by use of polydioxanone mesh will helpful for clinical applications.

Three Listeria monocytogenes strains isolated from clinical cerebrospinal fluid samples. A PCR was performed by using oligonuclotide primers derived from the invasion-associated protein(iap) related gene sequence. As a result of PCR, we obtained 287-bp DNA fragment of specific product to L. monocytogenes species. The chromsomal DNA of genera Listeria species were subjected to southern blot hybridization with HRP-labeled 287-bp DNA probe to produce a L. monocytogenes banding pattern. In the cases of 10-fold dilution of L. monocytogenes cells, 8 x 10(2) cells/ml were detected by PCR.

OBJECTIVE: Our purpose was to compare the safety and efficacy of intravaginally administered misoprostol(PGE1) versus dinoprostone(PGE2) for labor induction in a prospective controlled trial. METHOD: One hundred eleven patients for labor induction (including preterm rupture of membranes) were randomly assigned to receive either misoprostol 50microgram or dinoprostone 3mg intravaginally. The interval of doses was 8 hours after first dose, with a potential maximum of six dose until active labor pain was achieved. RESULTS: Among 111 patients enrolled, 55 were randomized to receive misoprostol 50microgram and 56 to receive dinoprostone 3mg with every 8 hours interval intravaginally. There were no significant differences in demographic characteristics except in Bishop score(3.81+/-1.52 vs 4.38+/-1.29, P<0.05). There were no significant differences in indications for labor induction. The interval of induction to delivery was shorter in the misoprostol group(750.8+/-518.8min) than in the dinoprostone group(1264.1+/-730.7min). Delivery within 24 hours after administration occurred more often in the misoprostol group than in the dinoprostone group (86.3% vs 65.2%, P<0.05). More than two doses for completion of delivery were frequent in dinoprostone group(36.96% vs 9.8% in misoprostol group, P<0.05). Additional Oxytocin augmentation was needed more commonly in the misoprostol group(3.64%) than in the dinoprostone group(14.29%)(P<0.05), but no significant differences were noted between two groups in total oxytocin doses and indications. Tachysystole occurred more often in the misoprostol group (12.73% vs 1.79% in the dinoprostone, P<0.05) Precipitating delivery occurred more commonly in the misoprostol group(21.82% vs 7.14% in the dinoprostone group, P<0.05). No differences in the cesarean section rate, fetal heart rate abnormalities, hyperstimulation syndrome, meconium staining, fetal outcome (Apgar score at 1 and 5 minutes, birth weight), and marternal outcome (nausea and vomitting, postpartum bleeding) were noted. The cost of misoprosl is one hundredth cheaper than dinoprostone. There was no significant differences in the fetal outcome and maternal outcome. CONCLUSION: These results suggest that intravaginal misoprostol(PGE1) is a safe drug for labor induction which is more effective and cheaper compare to intravaginal dinoprostone(PGE2).
