Purpose: The aim of this study was to investigate drug prescription patterns for the treatment of asthma and chronic obstructive pulmonary disease (COPD) patients in Korea. Methods: Ambulatory adult patients who were diagnosed and received treatment for the asthma (ICD-10 code J45) or COPD (ICD-10 code J44) from January 2009 to September 2011 in two independent secondary hospitals in Korea were enrolled in this study. Prescribed drug lists were generated based on the evidence-based guidelines and prescribed drug dosage forms were identified from the patient medical records and computerized drug prescription databases of the study centers. Results: Total numbers of asthma and COPD patient enrolled in this study were 2,432 and 2,615, respectively. Individual prescription-based accumulated numbers of patient were 12,021 for asthma and 16,584 for COPD. The most commonly prescribed three drugs were oral predisolone, oral formoterol and oral montelukast for asthma and oral formoterol, oral doxofylline and inhaled tiotropium for COPD. Frequencies of oral drugs were 83.4% and 63.3% while inhalers were 16.4% and 30.2%, for asthma and COPD, respectively. Conclusion: The oral treatment was prescribed more in asthma and COPD patients than inhalers. To enhance the compliance of evidence-based guidelines for these chronic airway diseases, more realistic and specific strategies to increase the use of inhalers recommended as primary treatment options for asthma and COPD would be required.

This study was carried out to compare the semen characteristics, frozen-thawed sperm viability and testosterone concentration and in vitro fertilization (IVF) and development of in vitro matured pig oocytes between two Yorkshire boars. Semen and blood samples were collected once per week from October to November 2002 from two adult Yorkshire boars at 18 months of age with 170 kg body weight. Sperm were deep frozen in 5 ml maxi-straws with lactose-egg yolk and N-acetyl-D-glucosamine (LEN) diluent and stored in liquid nitrogen. Blood samples were obtained at 10 a.m. by inserting a 21 gauge, hypodermic needle attached to 10 ml syringe into surface veins in the ear. The concentration of testosterone was determined by Competitive Enzyme Immunoassay. Ovaries were collected from prepubertal gilts at a local slaughter house. Cumulus oocyte complexes were aspirated from antral follicles (3 to 6 mm in diameter). The medium used for oocyte maturation was modified TCM 199. After about 22 h of culture, oocytes were cultured without cysteamine and hormones for 22 h at $38.5^{\circ}C$, 5% $CO_2$ in air. For IVF, one frozen 5 ml straw was thawed at $52^{\circ}C$in 40 sec and was diluted with 20 ml Beltsville thawing solution at room temperature. Sperm were washed 2 times in mTLP-PVA and inseminated without preincubation after thawing. Oocytes were inseminated with $2{\times}10^7$/ml sperm concentration. Oocytes were coincubated for 6 h in 500 ${\mu}$l mTBM fertilization medium. At 6 h after IVF, oocytes were transferred into 500 ${\mu}$l NCSU-23 culture medium for further culture of 48 and 144 h. There were no significant differences in the semen volume, motility, normal acrosome morphology and sperm concentration of raw semen between A and B of Yorkshire boar. However, motility and normal acrosome of boar A were higher than those of boar B at 0.5, 2, 3, 4, 5 and 6 h incubations of frozen-thawed sperm. Testosterone concentration (3.75 ng/ml) of boar A was higher than that (2.34 ng/ml) of boar B. The rate of blastocyst formation (15.1%) of boar A was higher than that (10.4%) of boar B. In conclusion, serum testosterone concentration of boar showed very important role for the frozen-thawed sperm viability and the blastocyst formation of pig oocytes matured in vitro.

The variations of both thiamine and riboflavin value in the organs, viz. liver, small intestine, spleen and kidney of the rats were measured for observing some metabolic changes in the animals during fasting and feeding different quality of diets without V-E supplement. The animal used for the experiment was adult female ablino rat from a pure strain, weighing 225-280g. The animals were divided into 6 groups; the control group, the high carbohydrate diet group, the high carbohydrate diet with V-E group, the high protein diet group, the high protein diet with V-E group, and fasting group. The result obtained are summarized as follows; 1. The thiamine contents in the liver were once increased during early stage of starvation compared with the control group, thereafter they were decreased on the 8 days fasting while the contents in the small intestine and spleen were decreased during 1 to 8 days fasting. 2. The riboflavin contents in the liver and kidney were increased during starvation and the content in the small intestine was no marked change compared with control group. 3. The thiamine contents in the liver and small intestine during feeding the high carbohydrate with V-E supplement diet group were lower than that of the diet without V-E group and the content in the spleen was increased by feeding V-E enriched high carbohydrate diet. 4. The thiamine contents in the liver, small intestine and spleen during feeding the V-E supplemented diets were lower than that of the non-supplemented one's. 5. The riboflavin contents in the liver, small intestine, and kidney were increased during feeding the high carbohydrate diet compared to the control group, and they were decreased during feeding the V-E enriched high carbohydrate diet. 6. The riboflavin contents in each organ were increased during feeding the high protein diet compared to the control group, and they were much increased during 20 to 30 days of feeding the V-E supplemented high protein diet. 7. Therefore, as the above results showed, the variation of thiamine value in the each organs were not markedly changed during feeding different quality of the diets. The thiamine and riboflavin contents in the each organ in the V-E enriched high carbohydrate diet group were lower than without V-E supplemented one's The riboflavin contents in each organ were increased during feeding the high protein diet compared with the control group and the centents were increased during 20 to 30 days of the feeding V-E enriched high protein diet.

소아는 성인보다 장기의 방사선에 대한 감수성이 크고 성장 중이기 때문에 더 민감하다. 피폭으로 인한 부작용을 겪는 기대수명이 길기 때문에 피폭선량의 관리가 어른의 경우보다 중요하게 다뤄진다. 본 연구는 10세 팬텀을 사용하여 현재 우리나라에 권고되어 있는 5세 소아의 촬영기준과 입사표면선량의 적합성을 확인하고 추가적으로 제시된 촬영기준으로 장기흡수선량을 측정해보았다. 임상에서 사용 중인 5세와 10세의 촬영조건과 장기흡수선량, 입사표면선량을 비교하였다. 임상 5세 촬영조건이 권고촬영조건보다 약간 높으며 임상 10세 촬영조건은 많이 높게 나타났다. 또한 권고 촬영조건으로 ESD를 측정한 결과 임상 촬영조건의 ESD가 43% 높게 나타났으며 10세의 ESD는 5세의 권고 촬영조건의 ESD 보다 126% 증가를 나타냈다. 5세의 권고된 ESD와 임상 촬영조건에 의한 ESD를 비교한 결과 31.6%의 차이를 나타냈다. 5세의 권고 촬영조건과 임상 촬영조건에 의한 장기흡수선량은 큰 차이는 없으나 흉부와 골반검사에서는 차이가 컸다. 그러나 10세의 임상 촬영조건에 의한 장기흡수선량을 비교하면 월등한 차이가 있었음을 알 수 있었다. 따라서 소아의 권고 선량에 대한 더욱 세분화된 기준안이 연구되어야 할 것으로 사료된다.

Dyslipidemia is the multiple lipid metabolic disorders which is one of the high risk factors for the atherosclerotic diseases. It increases the morbidity and mortality and therefore, must be treated with antilipidemic agents. HMG-Co A reductase inhibitors (statins), one of many antidyslipidemic agents, have shown to be significant improvement from the various cholesterol levels. Especially, data from many comparative trials suggest that rosuvastatin is more effective than atorvastatin among many other statins. The aims of this study were to evaluate the efficacy and safety between rosuvastatin and atorvastatin in the treatment of Korean patients with dyslipidemia. Currently the Korean Society of Lipidology and Atherosclerosis based on the Korean health screening data suggests that Korean patients with dyslipidemia should be treated by the target cholesterol levels according to the Adult Treatment Panel III guidelines of the US National Cholesterol Education Program (NCEP-ATP III). We reviewed retrospectively all medical histories of the total 392 dyslipidemic patients with atorvastatin or rosuvastatin from June 1st, 2004 to August 31st, 2006 in Chungbuk National University Medical Center. Patients were classified as total 4 groups by the NCEP-ATP III Guidelines. The numbers of enrolled patients were each 5 mg atorvastatin (n=34), 10 mg atorvastatin (n=148), 5 mg rosuvastatin (n=94) and 10 mg rosuvastatin (n=82). In comparison between groups, rosuvastatin groups in the lowering LDL-C had better efficacies, and the results were each 22% (5 mg atorvastatin), 33.3% (10 mg atorvastatin), 35% (5 mg rosuvastatin) and 41.3% (10 mg rosuvastatin) with the dose relationship (P=0.000). Rosuvastatin groups also have shown to be more significantly reducing Total Cholesterol levels compared to atorvastatin groups with the no dose relationship (P=0.000). In the lowering of non-HDL cholesteroles, rosuvastatin groups showed significantly better efficacies than atorvastatin with the dose-relationship (P=0.000). Each medication groups did not demonstrate the differences in the changing of HDL cholesterol and triglyceride levels (P=0.096, 0.309, respectively). In conclusion, rosuvastatin was better efficacious than atrovastatin in reducing LDL-C Total Chol, and Tg. Therefore, rosuvastatin is a good antilipidemic agents for Korean patients with dyslipidemia and it can use to minimize the morbidity and mortality related to the cardiovascular diseases in Korean.

Tapeworms of the genus Spirometra are pseudophyllidean cestodes endemic in Korea. At present, it is unclear which Spirometra species are responsible for causing human infections, and little information is available on the epidemiological profiles of Spirometra species infecting humans in Korea. Between 1979 and 2009, a total of 50 spargana from human patients and 2 adult specimens obtained from experimentally infected carnivorous animals were analyzed according to genetic and taxonomic criteria and classified as Spirometra erinaceieuropaei or Spirometra decipiens depending on the morphology. Morphologically, S. erinaceieuropaei and S. decipiens are different in that the spirally coiled uterus in S. erinaceieuropaei has 5-7 complete coils, while in S. decipiens it has only 4.5 coils. In addition, there is a 9.3% (146/1,566) sequence different between S. erinaceieuropaei and S. decipiens in the cox1 gene. Partial cox1 sequences (390 bp) from 35 Korean isolates showed 99.4% (388/390) similarity with the reference sequence of S. erinaceieuropaei from Korea (G1724; GenBank KJ599680) and an additional 15 Korean isolates revealed 99.2% (387/390) similarity with the reference sequences of S. decipiens from Korea (G1657; GenBank KJ599679). Based on morphologic and molecular databases, the estimated population ratio of S. erinaceieuropaei to S. decipiens was 35: 15. Our results indicate that both S. erinaceieuropaei and S. decipiens found in Korea infect humans, with S. erinaceieuropaei being 2 times more prevalent than S. decipiens. This study is the first to report human sparganosis caused by S. decipiens in humans in Korea.

Obstructive Sleep Apnea-Hypopnea Syndrome (OSAHS) is a disorder characterized by the repetitive collapse of the pharyngeal airway during sleep, which leads to oxygen desaturation, sleep fragmentation, daytime sleepiness, and increased risk for hypertension and stroke. We investigated the clinical factors related to the severity of OSAHS. Polysomnography was performed in three hundred and ninety five consecutive adult patients with clinical symptoms of obstructive sleep apnea syndrome. All patients completed the sleep questionnaire and the Epworth Sleepiness Scale before polysomnography. Patients were classified into four groups based on the severity of their polysomnographic data: Non-OSA group, characterized by Apnea-Hypopnea Index (AHI) < 5; mild OSA group, by AHI 5-15; moderate OSA group, by AHI 16-30; and severe OSA group, by AHI > 30. Neck circumference was also measured at the cricothyroid level. A total of 395 patients (336 men and 59 women) were studied. In the non-OSA group, there were 55 patients; their mean neck circumference was $39.63{\pm}4.24cm$ and mean BMI was $24.48{\pm}3.53$. In the mild group, there were 101 patients; their mean neck circumference was $41.93{\pm}3.75cm$ and mean BMI was $25.33{\pm}2.94$. In the moderated group, there were 93 patients; their mean neck circumference was $43.27{\pm}3.50cm$ and BMI was $25.90{\pm}2.88$. In the severe group, there were 146 patients; their mean neck circumference was $44.94{\pm}3.93cm$ and mean BMI was $26.81{\pm}3.76$. Men had significantly larger neck circumference than women ($Mean{\pm}SD$, $43.72{\pm}3.83$ vs $39.17{\pm}4.30$, p < 0.001), and higher AHI than women ($29.12{\pm}22.65$ vs $14.63{\pm}14.11$, p < 0.001). Multiple regression analysis revealed that neck circumference was the most significant predictor of AHI. Neck circumference and BMI were positively correlated with the severity of OSAHS. The severity of OSAHS was greater in men than in women.
