A 24 year-old Korean male, has had an eruption on the Lt. foot for 3 years. The lesion consists of single large macule of reddish purplish brown coloration scattered over the great toe, dorsum and inner part of the Lt. foot. Recently, there is no new lesions and lymphadenopathy on any part of the body. Laboratory tests were all negative, including serology. X-ray findings of the chest and Lt. foot showed normal limits but, angiographic findings which was performed under the local anesthesia through the femoral artery showed the arterio-venous plexus and markedly increased vascularity on the inner side of Lt foot area. Biopsy of a macule on the inner part of the Lt. foot was confirmed as Kaposi's sarcoma. X-ray therapy (100Kv at 50cm distance with 2 mm of AL. filter) was directed to the involved sites daily for 6 days to a total of 1,800 roentogens, after lesion was progressively improved day by day.

Nitinol wires are now widely used in the orthodontic field because of their unique shape memory effect and superelasticity. But sometimes Nitinol wires are deformed in clinical use. Fatigue load is possible cause of Nitinol deformation. To determine the effect of fatigue load to the mechanical properties of Nitinol, various fatigue cycle(1X10(4), 2X10(4), 3X10(4), 4X10(4), 5X10(4), 1X10(5)) were applied to 0.017 X 0.025 inch Nitinol. The results obtained were as follows; 1. Applied load increased as fatigue cycle increased in three point bending test. 2. Maximum tensile strength and elongation decreased as fatigue cycle increased. 3. In SEM, brittle fracture pattern was increased when fatigue cycle increased.

Biomechanical reactions of tooth movement are the combination of bone formation and resorption, in which many paracrine factors are involved. The sex hormone is one of the paracrine factors and the sex hormonal level of an adult female varies according to the body condition, e.g. mensturation, pregnancy, postmenopause, etc. Although the exact mechanism is not clarified yet, estrogen and progesterone are known to regulate the function of osteoblast. Again osteoblast is reported to affect the function of osteoclast. The purpose of this study is to determine the influence of the female sex hormone, estrogen and progesterone, on the cell proliferation and activity of HOS and ROS17/2.8 cell line. The observed results were as follows. 1. Estrogen inhibited HOS cell proliferation and promoted ROS17/2.8 cell proliferation. 2. Estrogen increased the activity of alkaline phosphatase of HOS cell and reduced the activity of alkaline phosphatase of ROS17/2.8 cell. 3. Progesterone inhibited the proliferation of HOS and ROS17/2.8 cell, but had no influence on the activity of alkaline phosphatase. 4. Estrogen and progeterone did not have any particular effects on the activity of super oxide, nitric oxide and gelatinase of HOS and ROS17/2.8 cell.

Pollinosis is one of the allergic diseases which caused by airborne pollens from allergic plants, such as allergic rhinitis, asthma, and allergic conjunctivitis. The distribution of pollens in the air is fully related to weather condition, especially temperature and humidity, etc. This study is focused on the evaluation of the relation between pollen count and the outbreak of allergic diseases (symptom index) from allergic patients in Korea and this data would be necessary to evaluate Korean own allergy index for pollen forecasting system. Airborne particles carrying allergens were collected daily from nationwide 8 stations (Seoul, Guri, Daejeon, Daegu, Kwangju, Busan, Kangneung, and Jeju) by using 7 days-Burkard sampler (Burkard Manufacturing Co Ltd, Hertfordshire, UK) for 10 year in South Korea (March 1, 2008-October 30, 2008). They were counted and recorded along with the weather factors. Symptom index was evaluated and recorded by calling to allergic patients daily. Airborne pollen has two peak seasons that is May and September in Korea. The peak season for mold was June. There was the tree pollen seasons from the middle of February to late July, then followed during the grasses and weed season from the middle of July to the end of October. Ragweed was one of the most common pollen of autumn in Korea. In skin prick test, Ragweed was the highest sensitization rate (5.9%), followed by Mugwort (5.8%), alder (4.9%), birch (4.8%), oak grasses among the pollen extracts in Korean school aged children. Ragweed pollen counts were gradually increased since 2000. In same period, sensitization rates for airborne pollen, especially weeds in Korean children were increased annually (1999: 4.4%, 2000: 7.1%, 2001: 7.4%, 2002: 8.5%, 2003: 7.7%). There are significantly related between symptom index from allergic patients and allergic pollen concentrations. Sensitization rates for pollens are increased in Korean children with age. There are significantly related between symptom index from allergic patients and allergic pollen concentrations. Risk Grade of pollen for allergy pollen forecast among each allergic plant was established and still remain to confirm it.

Intravenous leiomyomatosis is a rare entity of benign smooth muscle invading into the lumen of veins. We describe a case of intracardiac leiomyomatosis originating from the right gonadal vein, growing in the inferior vena cava, and extending into the right atrium. A 54 years old woman presented with chest discomfort and syncope four years after the removal of an uterine leiomyoma. The tumor was successfully removed in a two-staged operation using total circulatory arrest with a cardiopulmonary bypass, which proved to be a histologically benign leiomyoma. Although these tumors are histologically benign, they sometimes extend into the cardiac cavity and can cause sudden death due to their incarceration into the atrioventircular orifice. We report this rare case with a review of the literature.

PURPOSE: The number of patients waiting for organ transplantation continues to grow as technical and pharmacological advances increase the success rate of transplantation procedures, while organs are donated by few of the thousands of potential donors who die every year. The organ transplantation continues to be the best treatment for many end-stage diseases of the heart, liver, kidneys, and other organs. Many organ procurement failures have been attributed to a failure to identify patients with nonsurvivable central nervous system injury or disease as potential organ donors or failure to maintain a hemodynamic stability or failure to request consent for donation from next to kin. This study has been done for investigating the factors that influence the organ procurement rate in brain dead donors. METHODS: Of the 259 brain dead donors in the Asan Medical Center, from January 1991 to April 2003, 189 brain dead donors donated solid organs excluding conea. We retrospectively reviewed the medical records and the data of the transplantation center. A hemodynamic stability is defined as systolic blood pressure more than 90~100 mmHg with the use of low-dose vasopressor (dopamine less than 10microgram/ kg/min). RESULTS: From January 1991 to April 2003, the procurement rates of liver, heart, kidney and pancreas were 39% (n=75), 40% (n=76), 97% (n=184) and 17% (n=33), respectively. The procurement rates according to age were 26% in <20 years (n=49), 30% in 21~30 years (n=56), 20% in 31~40 years (n=37), 19% in 41~50 years (n=36), and 5% in >50 years (n=11). The major. causes of death among potential organ donors were traffic accident (59%) and cerebrovascular events (33%). In traffic accident, the procurement rates of liver, heart, kidney and pancreas were 42% (n=47), 37% (n=41), 98% (n=109) and 16% (n=18), and in cerebrovascular events, 33% (n=21), 38% (n=24), 97% (n=61) and 19% (n=12). Multiple organs were donated in the hemodynamically stable donors. CONCLUSION: Aggressive resuscitation and hemodynamically stabilization of all brain dead donors are important factors that may increase procurement rates.

PURPOSE: There are a number of reports suggesting that widespread propagation of weeds and high concentration of weed pollen have been contributed to climate change. We investigated the interrelationship between allergenic pollen concentration, allergic symptom and meteorological factor. METHODS: We collected data of pollen concentration and meteorological factors in 7 stations nationwide during between 1998 and 2012. We recruited total 297 allergic patients sensitized to weed pollens from each station, conducted a survey about allergic symptom, and calculated symptom index. We surveyed the vegetation area of ragweed and Japanese hop. Based on these data, we performed the long-term trend analysis (X11-ARIMA, autoregressive integrated moving average) on regional pollen concentration, and correlation analysis to investigate the interrelation between weed pollen concentration, allery symptom index and meteorological factor. We have also done regression analysis on vegetation area and maximal pollen concentration. RESULTS: Long-term trend analysis showed the increasing trend of pllen concentration in Seoul. Weed pollen concentration, allergy symptom index and each meteorological factor were not correlated significantly. Regression analysis revealed that increase of weed vegetation area results in increase of weed pollen concentration. Through this regression equation, we estimated the vegetation area that can product pollen concentration triggering allergenic risk. CONCLUSION: Meteorological factors, pollen concentration and allergic symptoms should be consistently assessed and the relationship between each factor should be analyzed, considering climate change. It is necessary to verify the equation for pollen estimation by vegetation area and set up a policy for vegetation control focused on the reduction of allergenic pollen.
