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.

3.Change of mechanical properties in Nitinol by fatigue load.
Korean Journal of Orthodontics 1993;23(4):725-734
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.

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.

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.

PURPOSE: The distribution of pollens in the air is mainly related to the weather conditions, especially temperature and humidity. This study focused on the evaluation of the relationship between pollen count and the outbreak of allergic diseases (symptom index) from allergic patients in Korea in order to determine Korean own allergy risk grade for the pollen forecasting system. METHODS: Airborne particles carrying allergens were collected daily in nationwide 8 stations (Seoul, Guri, Daejeon, Daegu, Kwangju Busan, Kangneung, and Jeju) by using 7 day- Burkard sampler in South Korea for 8 months (March 1, 2008-October 31, 2008). They were counted and recorded along with weather factors. Symptom index was calculated and recorded by phone calling to allergic patients 3 times a week. RESULTS: Airborne pollens have 2 peak seasons (May and September) in Korea. In the skin prick test, ragweed was the highest sensitization rate (5.9%), followed by mugwort (5.8 %), alder (4.9%), birch (4.8%) and oak grasses among the pollen extracts in Korean school-aged children. There are significant relationship between symptom index of allergic patients and allergic pollen concentrations. Korean own risk grade of pollen allergy was made by using the data from this study. CONCLUSION: Risk grade of pollens for allergy pollen forecast among each allergic plant was established. Further studies are needed to confirm it our result.

The old calendar of pollens did not reflect current pollen distribution and concentrations that can be influenced by changes of weather and environment of each region in South Korea. A new pollen calendar of allergenic pollens was made based on the data on pollen concentrations obtained in eight regions nationwide between 1997 and 2009. The distribution of pollen was assessed every day at 8 areas (Seoul, Guri, Busan, Daegu, Jeonju, Kwangju, Kangneung, and Jeju) for 12 years between July 1, 1997 and June 30, 2009. Pollens were collected by using Burkard 7-day sampler (Burkard Manufacturing Co Ltd, UK). Pollens which were stained with Calberla's fuchsin staining solution were identified and counted. Pine became the highest pollen in May, and the pollen concentrations of oak and birch also became high. Ragweed appeared in the middle of August and showed the highest pollen concentration in the middles of September. Japanese hop showed a high concentration between the middle of August and the end of September, and mugwort appeared in the middles of August and its concentration increased up until early September. In Kangneung, birch appeared earlier, pine showed a higher pollen concentration than in the other areas. In Daegu, Oriental thuja and alder produced a large concentration of pollens. Pine produced a large concentration of pollens between the middle of April and the end of May. Weeds showed higher concentrations in September and mugwort appeared earlier than ragweed. In Busan the time of flowering is relatively early, and alder and Oriental thuja appeared earliest among all areas. In Kwangju, Oriental thuja and hazelnut appeared in early February. Japanese cedar showed the highest pollen concentration in March in Jeju. In conclusion, update information on pollen calendar in South Korea should be provided for allergic patients through the website to manage and prevent the pollinosis.

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.
