  • Objective: To clinically validate the feasibility and accuracy of cine images acquired through the multitasking method, with no electrocardiogram gating and free-breathing, in measuring left ventricular (LV) function indices by comparing them with those acquired through the balanced steady-state free precession (bSSFP) method, with multiple breath-holds and electrocardiogram gating. Materials and Methods: Forty-three healthy volunteers (female:male, 30:13; mean age, 23.1 ± 2.3 years) and 36 patients requiring an assessment of LV function for various clinical indications (female:male, 22:14; 57.8 ± 11.3 years) were enrolled in this prospective study. Each participant underwent cardiac magnetic resonance imaging (MRI) using the multiple breath-hold bSSFP method and free-breathing multitasking method. LV function parameters were measured for both MRI methods. Image quality was assessed through subjective image quality scores (1 to 5) and calculation of the contrast-to-noise ratio (CNR) between the myocardium and blood pool. Differences between the two MRI methods were analyzed using the Bland-Altman plot, paired t-test, or Wilcoxon signed-rank test, as appropriate. Results: LV ejection fraction (LVEF) was not significantly different between the two MRI methods (P = 0.222 in healthy volunteers and P = 0.343 in patients). LV end-diastolic mass was slightly overestimated with multitasking in both healthy volunteers (multitasking vs. bSSFP, 60.5 ± 10.7 g vs. 58.0 ± 10.4 g, respectively; P < 0.001) and patients (69.4 ± 18.1 g vs. 66.8 ± 18.0 g, respectively; P = 0.003). Acceptable and comparable image quality was achieved for both MRI methods (multitasking vs. bSSFP, 4.5 ± 0.7 vs. 4.6 ± 0.6, respectively; P = 0.203). The CNR between the myocardium and blood pool showed no significant differences between the two MRI methods (18.89 ± 6.65 vs. 18.19 ± 5.83, respectively; P = 0.480). Conclusion: Multitasking-derived cine images obtained without electrocardiogram gating and breath-holding achieved similar image quality and accurate quantification of LVEF in healthy volunteers and patients.

  • Hydrogen peroxide and methyl hydroperoxide were measured over the northwestern Pacific Ocean during NASA's PEM (Pacific Exploratory Mission) -West. The first experiment (PEM -West A) was conducted in the fall of 1991 and PEM-West B in the early spring of 1994. Hydroperoxide data were obtained on board the NASA DC -8 aircraft through the entire depth of the troposphere. Average concentrations of both H$_2$O$_2$and CH$_3$OOH were higher during PEM -West A than B. The seasonal difference in hydroperoxide distribution was determined by the degree of photochemical activities and the strength and location of jetstream, which led to extensive and rapid continental outflow during the PEM-West B. While for H$_2$O$_2$distribution, a longitudinal gradient was more apparent than a latitudinal gradient, it was opposite for the CH$_3$OOH distribution. The longitudinal gradient indicates the proximity to the anthropogenic sources from the Asian continent, but the latitudinal gradient reflects photochemical activity. During PEM -West B, the ratio of C$_2$H$_2$/CO, a tracer for continental emission was raised and high concentrations of H$_2$O$_2$were associated with high ratios. The flux of hydroperoxide toward the North Pacific was also enhanced in the early spring. The eastward fluxes of H$_2$O$_2$ were 9% and 17% of the average photochemical production over the Pacific Basin between 140°E and 130°W during PEM-West A and B, respectively. For CH$_3$OOH, these ratios were 8% and 13%. Considering the lifetime of hydroperoxide and the rapid transport of pollutants, the export of hydroperoxide with other oxidants would have a significant influence on oxidant cycles over the North Pacific during winter/spring.

  • Aims: This overview summarizes the existing evidence on acupuncture for cancer-related pain. Methods: Literature searches were conducted in 7 databases. All clinical studies of acupuncture, electroacupuncture, ear acupuncture and transcutaneous electrical nerve stimulation (TENS) in cancer patients with the main outcome measure of pain were included. Results: Of the 8 studies included, one high quality randomized clinical trial (RCT) of ear acupuncture showed statistically significant pain relief in comparison with placebo ear acupuncture. All the other studies were either non-blinded (n = 2) or uncontrolled clinical trials (n = 5). Most investigations suffered from methodological flaws such as inadequate study design, poor reporting of results, small sample size and overestimation of the results. Conclusions: The current evidence does not support the use of acupuncture as an adjunctive analgesic method for cancer patients. Only one high quality RCT showed promising results thus warranting further investigation into this under-researched area.

  • The importance of measurement of health-related quality of life (HRQL) cannot be overemphasized. However, efforts to implement HRQL measurement often fail because of differences in definition and insufficient information about available measures. In this paper, many available HRQL measures are reviewed, which have been designed for, or frequently used with, people with cancer in order to aid in the evaluation of effects of oriental medicine on cancer patients. A total of 28 articles were selected from three different databases. The selected articles were analyzed according to three aspects of application of the Korean version of HRQL measures, namely generic, disease specific and symptoms related instruments. Nine HRQL measures are completed with Korean validation and data collection under contact and permission of the author. However, research studies that reported data on quality of life (QOL) in cancer patients treated with oriental medicine were wholly lacking. It is recommended that further studies be performed, using methods of data collection whose validity and reliability has been confirmed.

  • Objective : This study aimed to investigate differential cancer incidence among Sasangin comparing to healthy subjects in the Republic of Korea. Methods : The medical records of 169 patients who had taken diagnosis of Sasang constitution from October 2004 to January 2007 at the East-West Cancer Center in Dunsan Oriental Hospital of Daejeon University were reviewed. Diagnosis was done by Questionnaire for Sasang Constitution ClassificationII (QSCCII). Results : Among the 169 patients, 37.9%, 22.5% and 39.6% belonged to Soyangin, Taeumin and Soeumin, respectively. This is significantly different from the distribution rate of Sasang in amonghealthy subjects (29.1%, 46.9% and 24.0% respectively to Soyangin, Taeumin and Soeumin). This pattern appeared in a similar way among individual cancer analysis: breast cancer (37.5%, 21.9%, 40.6%), colon cancer (41.7%, 20.8% 37.5%), and HCC (35.0%, 20.0%, 45.0%). Stomach cancer typically showed remarkable incidence in Soeumin as high as 50.0% and lung cancer showed in Soyangin as high 46.7%, but it didn't have statistical significance. The mean age of 50.9 years was higher than for healthy people (46.3). Conclusion : Sasang distribution of cancer patients is different from that of healthy subjects. Further study is needed on individual cancers.

  • We report a case of an 85-year old man with an adenocarcinoma of the rectosigmoid colon (clinical stage II). Though tumor was resectable, the patient was considered to be inoperable because of old age and comorbidities such as asthma, diabetes and old myocardial infarction. He wanted to receive alternative care, so he was exclusively treated with standardized Allegern-removed Rhus verniciflua Stokes (aRVS) extract and other herbal medicine such as BOJUNGIKGI-TANG GAMIBANG. During 18 months, he has shown good performance status without transfusion. This report suggests that herbal treatment including standardized aRVS for rectosigmoid colon cancer could be an alternative treatment option when it is unabled to be treated by surgical resection.

  • Background: To investigate the effects of ASMase mediated endothelial cell apoptosis in multiple hypofractionated irradiations in CT26 tumor bearing mice. Materials and Methods: Thirty-five CT26 tumor bearing mice were subjected to single ionizing radiation (IR) of 0, 3, 6, 9, 12, 15, 18 Gy. Eight hours after IR, the mice were sacrificed and tumor tissues were used for CD31 immunohistochemistry staining, TUNEL and CD31 double staining, ASMase activity assay. Then 6 and 12 Gy were chosen for multiple hypofractionated IR experiments according to the above results. Each time after IR, 5 mice were sacrificed and assayed as above. Results: The ASMase activities were increased significantly after a single IR of 12 Gy or higher which was accompanied with remarkable increased endothelial cell apoptosis and decreased MVD. For 6 Gy which was not high enough to trigger ASMase activation, after 2 or more times of IR, the ASMase activities were significantly increased accompanied with remarkable increased endothelial cell apoptosis and decreased MVD. While for 12 Gy, after 2 or more times of IR, the ASMase activities and endothelial cell apoptosis rates were maintained without remarkable increase; however, the MVD was significantly decreased. What's more, the cancer cell apoptosis rates were significantly increased after multiple IR for both 6 Gy and 12 Gy. Conclusions: ASMase mediated endothelial cell apoptosis may play an important role in the process of multiple hypofractionated IR for CT26 colorectal carcinoma.

  • The purpose of this thesis is to find out how the upper garment styles in the Ancient East and est had been influenced with each other. Analytical studies conclude the fellowing findings: 1) Upper garment styles in the feat Asia and the Egypt already highly developed in 28th century B.C. and show us the original style of the wrap-over to the left and that of the round neckline(曲領). Upper garment of the open in the center front shown in Babylonia in 18th century B.C. had been inherited to the caftan of the Hebrew and later succeeded to the Persia. 2) The tunic styles of the round neckline, the wrap-over to the left and the open in the cotter front, which were the basic styles of the upper garment, had teen widely accepted to the central Asia and the East Asia, as well as the Northern Europe, from the West Asia. 3) The styles of the wrap-over to the right originated from China since it had begun to show in the Shang Dynasty(商代, 殷代). 4) The East and the West costumes had been very much intermixed in 4th century B.C. Alexander the Great of Macedoria in 4th century B.C. expanded his territory to the central Asia and built up the Bacteria, when the most western civilization had been greatly transmitted to the Orient. Meanwhile the tunic being clad in the West and Central Asia began to be worn by soldiers in the period of the Warring States in China (326-299 B.C.) and afterwards worn even by civil officials since the age of the T'ang Dynasty of China. 5) The Upper garments of the open in the center front, the wrap-over to the right, the wrap-over to the left and the round neckline were found in Korea, which mean that the upper garment styles in the Ancient Korea were intermixed of the factors from the West Asia, the central Asia and the East Asia. 6) The styles of costume in the East Asia were influenced by the West Asia through the central Asia. The upper garment styles Europe were also influenced by the West Asia. Thus the upper garment styles in the Ancient East and West had been mutually affected with each other.
