  • Recently, the proportion of the population older has increased rapidly. As the aged population is increasing, the prevalence of malignancy rises with age, too. We believe that the potential benefits of approach to cancer care in the elderly are self-evident. In order to investigate the characteristics of cancer in the elderly, we reviewed literature related with the biology of the aged with cancer. The elderly undergo age-related changes in their physiology which may result in altered tolerance to disease and to the requirements of the management of illness. The possible reasons for the increased prevalence of cancer in the elderly are a longer potential duration of exposure to carcinogens, a reduced ability of repair DNA and reduced host defences against malignancy. In general, cancer patients in the elderly have a shorter survival. Because it is impossible to offer the active treatment of cancer in the elderly. Also, they have the problems that the psychosocial change and reduce of physiological function such as absorption, metabolism and excretion. We hope that other groups will further research cancer in the elderly in future.

  • Background: Asian dust storms can be transported across eastern Asia. In vitro, Asian dust particle-induced inflammation and enhancement of the allergic reaction have been observed. However, the fibrotic effects of Asian dust particles are not clear. Production of transforming growth factor ${\beta}_1$ (TGF-${\beta}_1$) and fibronectin were investigated in the bronchial epithelial cells after exposure to Asian dust particulate matter (AD-PM10). Methods: During Asian dust storm periods, air samples were collected. The bronchial epithelial cells were exposed to AD-PM10 with and without the antioxidant, N-acetyl-L-cysteine (NAC). Then TGF-${\beta}_1$ and fibronectin were detected by Western blotting. The reactive oxygen species (ROS) was detected by the measurement of dicholorodihydrofluorescin (DCF), using a FACScan, and visualized by a confocal microscopy. Results: The expression of TGF-${\beta}_1$, fibronectin and ROS was high after being exposed to AD-PM10, compared to the control. NAC attenuated both TGF-${\beta}_1$ and fibronectin expression in the AD-PM10-exposed the bronchial epithelial cells. Conclusion: AD-PM10 may have fibrotic potential in the bronchial epithelial cells and the possible mechanism is AD-PM10-induced intracellular ROS.

  • Background : Pneumoconiosis is a parenchymal lung disease that results from the accumulation of coal dust in the lungs and the consequent tissue reaction. To evaluate the role of various personal factors in pneumoconiosis and the significance of some serologic markers for assessing the disease activity related to pneumoconiosis, the Rheumatoid Factor(RF), ${\alpha}_1$-AT, C-Reactive Protein(CRP), ceruloplasmin and fibrinogen levels were measured. Method : All the patients were males, 45-76 years old, and the mean duration of coal dust exposure was 23.2 years. 51 patients were classified as having Simple Pneumoconiosis (SP), 59 had Progressive Massive Fibrosis (PMF). Fifty eight men with ages ranging from 26-70 years were used as normal controls. The serum RF and CRP were titrated using an Autochemistry analyzer (HITACHI 7150 : Japan) and the ${\alpha}_1$-AT and ceruloplasmin levels were measured using a Nephelometer (Behring Nephelometer : Germany) and the fibrinogen levels were estimated by using an Autoanalyzer for hematologic coagulation. Result : There was a higher RF level in the SP, and PMF groups than in the control groups but there was no statistical difference. The CRP, ${\alpha}_1$-AT, and ceruloplasmin levels were also higher in the SP, and PMF groups. However, the fibrinogen concentration was within the normal ranges in both the SP and PMF groups. Conclusion : The CWP (Ed note : Define CWP) patients had significantly higher CRP, ${\alpha}_1$-AT, and ceruloplasmin levels compared to the control group. It is believed that these serologic changes could be used as a marker of the disease activity.

  • According to the Para. 5 of Art 2 of the Korean Nuclear Safety Regulations, which was revised in 1999, internal dose assessment as well as external one should be performed by law for employees at a nuclear power plant from 2003, and their estimate errors should also be within 50%. Thus, more accurate internal dosimetry becomes important. Corresponding to such regulation revision, we are developing a more accurate thyroid-uptake internal dosimetric system and have developed a Monte Carlo simulation code, the so-called CALEFF, to calculate the detection efficiency of the dosimetric system. In this paper, we calculated detection efficiencies with various test conditions by using the CALEFF code and discussed their characteristics. We may use the detection efficiency calculated by the code in calibrating the thyroid internal dose from measured data.

  • Objectives: Due to advance of science and IT technology, high tech imaging equipment like ultrasonography, CT, MRI and PET scan is constantly being developed and progressed; use of these techniques is needed for Korean medicine. Methods: Historical study was undertaken on the evidence of using ultrasonography. Normal organs and various sorts of diseases were also observed by ultrasonography. Results: Korean medicine judges disease of internal organs and condition of health by symptoms of functional disease and organic disease based on anatomical theory. Ultrasonography based on anatomical theory is non-invasive and free from radiation exposure and can be performed directly from clinical practice in real-time. Ultrasonography can be a big help for securing the stability of the internal organs in inserting needles in the thorax and abdomen as well as diagnosing functional and organic diseases based on anatomical theory. Conclusion: We look forward to a great development of scientification and objectification of Korean medicine by using and researching imaging equipment based on anatomical theory as well as ultrasonography.

  • Objectives: This study investigated the effect of SM-2015 on blood alcohol clearance and hangover. We undertook this study to test whether SM-2015 is effective in decreasing blood alcohol concentration and preventing the symptoms of alcohol-induced hangover. Methods: Twenty healthy volunteers participated in this randomized crossover study. All participants were classified between an SM-2015 intake group (test group) and a non-intake group (control group). The primary outcome measure was the difference in blood alcohol concentration and hangover severity scores between the test and control groups. The secondary outcome measure was the difference in a liver function test (LFT) between the test and control groups. Results: After alcohol exposure, the sensitivity scores of blood alcohol concentration and hangover symptoms (sleepiness, dizziness, nausea, weakness, stomach pain, diarrhea, and concentration disorder) were significantly decreased in the SM-2015 intake group compared with the non-intake group. There were no differences in the LFT results between the SM-2015 intake group and the non-intake group. Conclusions: SM-2015 is effective in decreasing blood alcohol concentration and preventing the symptoms of alcohol-induced hangover. Larger studies are required to confirm these findings.

  • A pressurizer is one of the major safety related equipment of nuclear power plants. In order to inspect and maintain the internal structures of a pressurizer, jumpers have to enter the pressurizer, in spite of the high dose exposure. Therefore, a tele-operated robotic manipulator has been developed, which consists of four parts with 2DOFs arms, a gripper, base frame, and control console. The task of this robotic manipulator is to extract the damaged electric heaters and inspect the internal structure of the pressurizer. The gripper hanging from the manipulator approaches the heaters and extracts the damaged heater by using a self-locking mechanism. In order to investigate the structural stability of the robotic manipulator, a stress analysis has been performed by using the ANSYS code. The results of this paper include the position control and vibration control of robotic gripper and the development of processing visual information for a vision sensor.

  • Cough is an important defensive reflex of the respiratory tract needed to clear and protect the upper airways, but it may become exaggerated and interfere quality of life. Gastroesophageal reflux disease (GERD) is one of the three most common causes of chronic unexplained cough. Diagnosing GERD related cough is challenging since many patients do not have esophagitis or an increased esophageal acid exposure during 24 h esophageal pH-metry. We treated two patients who had chronic cough, these subjects were diagnosed as Sikjeoksu (Shijisou, 食積嗽) and was administered Pyeongjingeonbi-tang (Pingchenjianpi-tang, 平陳健脾湯). First case had stuffiness below the heart and acid regurgitation with cough, but second case only had cough. After treatment, cough and other symptoms were improved. It showed that we must consider GERD on chronic cough patients.

  • Radiotherapy (RT) is a treatment modality that uses high-energy rays or radioactive agents to generate ionizing radiation against rapidly dividing cells. The main objective of using radiation in cancer therapy is to impair or halt the division of the tumor cells. Over the past few decades, advancements in technology, the introduction of newer methods of RT, and a better understanding of the pathophysiology of cancers have enabled physicians to deliver doses of radiation that match the exact dimensions of the tumor for greater efficacy, with minimal exposure of the surrounding tissues. However, RT has numerous complications, the most common being radiation proctitis (RP). It is characterized by damage to the rectal epithelium by secondary ionizing radiation. Based on the onset of signs and symptoms, post-radiotherapy RP can be classified as acute or chronic, each with varying levels of severity and complication rates. The treatment options available for RP are limited, with most of the data on treatment available from case reports or small studies. Here, we describe the types of RT used in modern-day medicine and radiation-mediated tissue injury. We have primarily focused on the classification, epidemiology, pathogenesis, clinical features, treatment strategies, complications, and prognosis of RP.
