A 39-year-old man, his 35-year-old wife, and their 13-year-old daughter were found dead in their home. The man and his daughter were found lying in her bedroom, with his head wrapped in a plastic bag connected to four helium gas cylinders by green polypropylene tubes. Fragments of the burnt ignition briquette were found in the bucket located at her feet. His wife was found in a decomposed state lying on her right side in her bedroom. Autopsy findings for the man were unremarkable except for cherry pink lividity; the blood carboxyhemoglobin concentration was 73%. Autopsy findings were unremarkable for the woman as well, except for a few petechial hemorrhages and conjunctival congestion. The daughter showed no definite abnormalities; however, her blood and lung contained helium gas. The deceased man's suicide note, evidence gathered at the scene, and postmortem examination revealed that this was a case of dyadic death.

Interruption of the aortic arch is an uncommon congenital cardiovascular malformation invariably accompanied by other cardiovascular anomalies. This carries a 76% mortality rate in the first month of life. We recently experienced a case of interruption of the aortic arch with patent ductus arteriosus in a 21-year-old man with systolic murmur. he did not showed any other symptoms or signs. Cardiac catheterization with angiography showed interruption of the aortic arch with many systemic arterial collaterals and patent ductus arteriosus.

PURPOSE: This study was designed to investigate whether vascular smooth muscle cells (VSMC) from the neointima showed any different response to antiproliferative agents, such as rapamycin or imatinib mesylate, compared to VSMCs from normal artery. MATERIALS AND METHODS: Intimal hyperplasia was made by carotid balloon in jury in male rats. Neointimal cells at 4 weeks after injury and normal VSMCs were extracted by enzymatic isolation method and cultured. Cell viability and proliferation were tested in VSMCs from injured left carotid artery and uninjured right carotid artery. Tests were repeated with rapamycin, imatinib mesylate or both in various concentrations. RESULTS: Rapamycin decreased cell viability only at a high concentration of 10(-5) M in uninjured VSMCs. Combined drugs decreased cell viability at a lower concentration of 10(-7) M in uninjured VSMCs, and at a higher concentration of 10(-5) M in neointimal cells. Overall, rapamycin showed cytocidal effects at a high concentration of 10(-5) M, whereas imatinib did not. Cell proliferation of neointima was significantly decreased along with the drug concentration. Cell proliferation of uninjured VSMCs was significantly decreased at higher drug concentrations. Combined drug therapy showed synergistic effects. Overall, neointimal cells are more susceptible to the antiproliferative effects of the drugs. CONCLUSION: Neointimal cells from the injured carotid artery are more susceptible to the antiproliferative effect of imatinib and rapamycin. Both drugs can be a used for the prevention of intimal hyperplasia, which could be investigated through further in vivo studies.

The visualization of coronary arteries by transthoracic two-dimensional echocardiography has been used for over 10 years. In many cases, the imaging quality is too poor to allow an anatomic evaluation. During the last few years, transesophageal echocardiography has been shown to provide optimal imaging quality in virtually all patients and of all cardiac structures including the coronary arteries. The purpose of this study was to test the ability of transesophageal echocardiography in the visualiation of the coronary arteries and assessment of coronary blood flow by transesophageal two-dimensional pulsed Doppler echocardiography. We Studied 285 patients, 91 men and 194 women, aged 16 to 81 year(mean 50.6 year men, mean 54.2 year women). We have been used a 5-MHz phased array transducer with incorporated color-coded Doppler. The left main coronary artery was visualized 95.1%, left circumflex artery 27.4, left anterior descending artery 21.4% and the main stem of the proximal right coronary artery 45.1%. The time-sequential left anterior descending artery flow pattern generally consisted of a small late systolic component and a large diastolic component. The peak flow velocity in the proximal left anterior descending artery during diastole was 40.8+/-8.0cm/sec(integrity 7.6+/-0.9) and during late systole was 18.5+/-5.5cm/sec(integrity 2.9+/-0.9). There were no complications during and after examination. This study suggests that transesophageal color-coded Doppler two-dimensional echocardiography appers to be a feasible noninvasive technique for imaging the proximal left coronary artery and the left anterior descending artery flow is detectable from the transesophageal approach.

Transesophageal echocardiography(TEE) is a new acoustic window to the cardiac structures and great vessels via retrocardiac esophagus. Because of the close relation between the esophagus and the heart, higher transducer frequencies can be applied, therefore leading to improved resolution and more accurate images than transthoracic echocardiography. We describe our experience with the first 353 awake patients. The procedure was well tolerated by the patients and associated with no major complications, within examination 10 to 20 minutes. Clinical diseases which appear to be suited for TEE includes 1) evaluation of native valve diseases, particulary mitral valve, pathologic valvular abnormalities and color Doppler regurgitant flows ; 2) assesment of prosthetic heart valves to better define malfunction and important pathologic associations ; 3) congenital heart disease, particularly atrial septal defect ; 4) endocarditis and detection of vegetations and complications ; 5) detection of thrombus and tumors, size, location, morphology, stalk ; and 6) aortic pathology including atherosclerosis, aneurysm and dissection. We conclude that transesophageal echocardiography is a new imaging technique that is rapidly evolving into a major tool for general cardiac imaging in a variety pathologic conditions and is a safe and useful tool in patients. Future advances in probe technology will continue to expand its applications.

PURPOSE: Although progenitor cells may contribute to intimal hyperplasia (IH) after arterial injury, positive contribution of IH is variable with type of injury or cells. This study was designed to examine whether differentiated muscle derived stem cells (MDSC) attenuate IH in rat. METHODS: MDSCs were retrieved using preplate techniques from rat calf muscle and MDSCs (preplate 6th culture fraction, pp6) were exposed to VEGF (50 ng/ml) for endothelial differentiation prior to injection. Male rats were divided into two groups (cell treated vs. control) and underwent carotid balloon injury with 2-Fr catheter. The virus containing Green fluorescent protein (GFP) gene was transfected into cells for monitoring. Cells (5x10(6)) were indwelled into carotid artery for 30 minutes after injury and then blood flow was restored. Arteries were harvested at various intervals (1, 2 and 4 weeks) after injury. The intima to media thickness ratio (IMTR) was calculated with morphometric analysis. RESULTS: Endothelial surface markers such as VE-CADHERIN were strongly expressed on differentiated MDSCs. At 4 weeks after injury, IH was predominantly observed in control group compared to cell treated group. The intensity of GFP was strongly observed at 1 week and declined at 4 weeks in carotid artery wall at MDSC group. CD31(+) endothelial cells were observed at MDSC group compared to control. The mean IMTR in cell treated groups were significantly lower than control at 2 weeks (P=0.005) and 4 weeks (P< or =0.001). CONCLUSION: Our study demonstrates that MDSCs therapy promotes re-endothelialization and leads to attenuation of IH after balloon injury in rat.

PURPOSE: In general, the depth of tumor invasion correlates with lymph node metastasis in gastric cancer, but some cases show a discrepancy between the tumor depth and nodal status. Therefore, this study was designed to investigate the factors affecting tumor growth patterns including the depth of invasion and lymph node metastasis. METHODS: The clinico-pathological characteristics of 1048 gastric cancer, from 1993 to 1999, were investigated. These cancer cases were divided into three groups: the early gastric cancer with lymph node metastasis (EP), the serosa infiltrated advanced cancer with no lymph node metastasis (SN), and the serosa infiltrated advanced gastric cancer with lymph node metastasis (SP) groups. The expression status of the proteins related with tumor growth, including matrix metalloproteinase-2 and 9 (MMP-2 and MMP-9), VEGF, nm23 and p53, were compared using immunohistochemical stain, p53 gene mutation, Microsatellite instability (MSI) and Loss of heterozygosity (LOH). RESULTS: There were 35 (3.4%) of the total cases in the EP group, and 10.1% in Early gatric cancer cases. The female ratio in the EP group was higher than in the SN group but this was not statistically significant. The most common gross types in the EP and SN groups were IIc and Borrmann type III, respectively, and the mean tumor size was largest in the SN group. The cell differentiation of the SN group was better than that in the EP group (68.6 vs. 41.2%). The levels of MMP-2 and -9 were higher in the SN and SP groups than those in the EP group. However, the levels of VEGF and nm23 between the groups were no different. The EP group had the highest degree of p53 mutation. There was no difference in the MSI and LOH expression status between the groups. CONCLUSION: There were some different growth patterns in the gastric cancers between the lymph node metastasis dominant (EP) and depth of infiltration dominant (SN) groups. MMP-2 and -9, tumor differentiation and mutated p53 gene exon may correlated with the tumor growth pattern. Further study is suggested to find the difference between the EP and SN groups, which could provide information on which factors determine nodal metastasis or the depth of a infiltration dominant growth pattern.

BACKGROUND/AIMS: Pancreatic cancer has a very poor prognosis, and early diagnosis is a way to increase the survival rate of patients. The purpose of this study was to develop pancreatic cancer-specific peptides for imaging studies. METHODS: Three pancreatic cancer cell lines, MIA PaCa-2, UACC-462, and BxPC-3, and a control cell line, CCD841, were used. Biopannings were performed on MIA PaCa-2 using a phage display library. After this, the peptides were synthesized and labeled with fluorescein isothiocyanate (FITC). Immunocytochemistry (ICC), enzyme-linked immunosorbent assay (ELISA), and fluorescence-activated cell sorter (FACS) were performed to examine the specific binding. To examine its therapeutic applications, a photosensitizer, chlorin e6 (Ce6), was conjugated on the peptide and photodynamic therapy was performed. Cell survival was investigated using a [3-(4,5-Dimethylthiazol-2-yl)-2,5-Diphenyltetrazolium Bromide] assay. RESULTS: After three biopannings, the phages were amplified from 1.4×104 to 3.2×105 plaque-forming units. The most strongly binding phage was selected from the ELISA and ICC results. FITC-labeled peptide, M5, in the three pancreatic cancer cell lines showed significantly higher immunofluorescence in the ICC experiments than that of CCD841. The higher binding ability to MIA PaCa-2 cells was confirmed from FACS analysis, which showed a right shift compared to CCD841. M5 bound to Ce6 showed a significantly lower cell survival rate than that of Ce6 alone in photodynamic therapy, which was observed consistently as a change in the tumor size and fluorescence intensity in MIA PaCa-2 cell-implanted animal models. CONCLUSIONS: This study showed that the noble peptide, M5, binds specifically to the pancreatic cancer cell line, MIA PaCa-2. The M5 peptide has potential use in future optical diagnostic and therapeutic purposes.
