A survey on biliary atresia was made among 26 members of the Korean Association of Pediatric Surgeons. The members were required to complete a questionnaire and a case registration form for each patient during the twentyone-year period of 1980-2000. Three hundred and eighty patients were registered from 18 institutions. The average number of patients per surgeon was one to two every year. The male to female ratio was 1:1.3. The age of patients on diagnosis with biliary atresia was on average $65.4{\pm} 36.2$ days old. The national distribution was 32.8% in Seoul, 25.3% in Gyoungki-Do, 21.6% in Gyoungsang-Do, 9.27% in Choongchung-Do, etc. in order. The most common clinical presentation was jaundice (98.4%) and change of stool color (86.2%) was second. Two hundred eighty (74.7%) of 375 patients were operated by 80 days of age. Three hundred thirty six (9 1.9%) of 366 patients were operated on by the original Kasai procedure, and 305 (84.3%) of 362 patients were observed by bile-drainage postoperatively. The overall postoperative complication rate was 18.5% and the overall postoperative mortality rate was 6.8%. The associated anomalies were observed in 72 cases (22.5%). One hundred ninty five (64.7%) of 302 patients have been alive in follow-up and 49 (25.1%) have survived over 5 years without problem after operation. Ascending cholangitis, varices and ascites affected survival significantly, and the important long-term prognostic factor was the occurrence of complications.
The acupuncture documentary characteristics of the "Chimgugapeulgyeong" can be summarized into 7 parts such as the following. 1. After Imeok(林億)'s revised edition of the "Gapeulgyeong(甲乙經)" was printed during the Song dynasty, there were no reprints during the Southern Song, Geum(金) and Won(元) eras, and the first printed edition that remains today is the 'Uihakyukgyeong edition[醫學六經本]' published by Omyeonhak(吳勉學) during the Mallyeok(萬曆) era of the Myeong(明) dynasty. This publication was put into the "Uitongjeongmaek(醫統正脈)" collection in the 29th year of the Manlleok(萬曆) era(1601). Most of the remaining copies have been restored during the Cheong dynasty at bookstores, and we can see that much was restored because of damage and missing characters. Also, the 'Namgyeokcho edition[藍格抄本]' and 'Yukgyeong edition[六經本]' of the Myeong dynasty do not come from the same original document, which allows the correction of the former in many places. However, this edition was not copied well, so the order of contents is different, and there are many mistakes. The 'Sagojeonseo edition[四庫全書本]' and the 'Gajeong edition[嘉靖本]', which Yeounsu(余云岫) quoted from, coincide with each other, making them worth much reference. So, the "Gapeulgyeong" and 'Yukgyeong edition' should be seen as the original, with the 'Myeongcho edition[明抄本]' as the main revision, and the 'Sago edition[四庫本]' as a reference edition. The so-called 'Chojeongtong edition(鈔正統本)' has many problems and marks of forgery, so therefore cannot be used in revising the "Gapeulgyeong" through comparison. 2. The table of contents[序例] in the front of the current edition was in the original edition and was not added by Imeok. The structure of sentences quoted by medical books before the Song dynasty coincide with this 'table of contents'. The "Gapeulgyeong" of the Song dynasty also coincide with the 'table of contents' but the edition remaining differs much from this 'table of contents' so it was edited or erased by people from future generations, especially after the Song dynasty. 3. The remaining edition of "Gapeulgyeong" consists of at least 4 parts. The original edited by Hwangbomil(皇甫謐), annotations added by medicinal practitioners before the Song dynasty, Imeok's revisionary annotations during the Song dynasty, and annotations after the Song dynasty. 4. Expressions such as 'Somun says[素問曰]' 'Gugwon says[九卷曰]' and explanatory annotations like 'Hae says[解曰]' are old writings from the original text and were not added by someone later. 5. Almost all of the 'Double lined small letter annotations[雙行小字注文]' of the 'Yukgyoeng edition' was by people during the Song dynasty. 6. There are many omitted and wrong letters in the remaining edition and there are also many places where future generations edited and supplemented the text. The table of contents differ greatly from the original text. 7. The medical books that quote "Gapeulgyeong" a lot are "Cheongeumyobang(千金要方)", "Oedaebiyobang(外臺秘要方)", "Seongjaechongrok(聖濟總錄)", "Chimgujasaenggyeong(鍼灸資生經)", "Yuyusinseo(幼幼新書)", and "Uihakgangmok(醫學綱目)" and such. However, the method used in using the text differs between the medical books, so the quotation from the same book comes from a quotation used by a doctor from a different era in one("Cheongeumyobang"), or the quotation was taken from each medical book("Chimgujasaenggyeong") or the quotation was all taken from another book("Yuyusinseo"). The reason we need to know about this problem properly is because we must use medical books that quote the original text of the "Gapeulgyeong" when we are looking for text that we can use to revise through comparison.
In oder to study the correlation between daily urinary output of sodium chloride and blood pressure, twenty four hour urine samples were collected from 224 cases (70 male and 154 female) of healthy Koreans whose age varied from 18 to 70 years old. The volume and concentration of sodium, chloride and potassium and total nitrogen were measured, along with the resting blood pressure. Results obtained are summarized as follows; 1. Daily urinary output was increased as a function of age. However, daily urinary output per unit sulface area was maintained at approximately 800 to 900 $ml/m^2$ in all age groups of male and it increased as a function of age in female groups. There was no significant difference between male and female. 2. The daily urinary sodium concentration was decreased gradually acceding to age in both sexes. Daily excretion of sodium was constant regardless of age in both sexes but especially high in 25-39 year female age group, which was slightly greater in males than in females. 3. The daily urinary chloride concentration was at approximately 250 meq/L in all age groups of male and which decreased as a function of age in females. 4. Hence the daily urinary output of sodium chloride was constant in all age groups of males which increased as a function of age in female groups. However, daily excretion of sodium chloride per unit sulface area was maintained at approximately 11 $gm/m^2$ in males and which increased as a function of age in females. 5. The daily urinary excretion of potassium was constant regardless of age in both sexes. 6. Urinary K/Na ratio was maintained at approximately 0.27 in males and 0.33 in females. 7. The daily urinary output of total nitrogen amount was approximately $8{\sim}10$ gm in males and $7{\sim}9$ gm in females. However, daily urinary output of nitrogen per unit sulface area was constant regardless of age in both sexes. 8. The systolic blood pressure was increased gradually according to the age in both sexes and was higher for males than females under 40 years of age. However, there was no significant difference between both sexes in ages over 40 years. 9. Quantitative comparisons indicated that daily urinary output and sodium chloride excretion are higher while daily potassium output, nitrogen excretion and urinary K/Na ratio are significantly lower among Koreans than a among Occidentals. These findings suggest that average Koreans live on low-protein and high-salt diet throughout their livers. Statistical result obtained may he summarized as follows; 10. The relation between blood pressure and sodium concentration of urine. The correlation between systolic blood pressure and sodium concentration was negatively associated for both sexes and the correlation coefficient was significant for females $({\gamma}_1=-.19<-{\gamma}_{152},\;_{0.05}=-0.159)$ and it was not significant for males $({\gamma}_1=-.19>-{\gamma}_{68},\;_{0.05}=-0.232)$ tut may be due to the sample size for males. The correlation between diastolic blood Pressure and sodium concentration was negatively associated for both sexes and the correlation coefficient was significant for males $({\gamma}_1=-.37<-{\gamma}_{68},\;0.05=-0.232)$ and the relation was not significant for females $({\gamma}_1=-.11>-{\gamma}_{152},\;_{0.05}=-0.159)$. 11. The relation between blood pressure and daily urinary sodium chloride excretion. The association between systolic blood pressure and sodium chloride excretion was positively correlated for both sexes and the relation was significant for females $({\gamma}_1=.20>{\gamma}_{152},\;_{0.05}= 0.159)$ and it was insignificant for males $({\gamma}_1=.09<{\gamma}_{68},\;_{0.05}=0.232)$, The relation between diastolic blood pressure and sodium chloride excretion was positively associated and insignificant for both sexes males $({\gamma}_1=.17<{\gamma}_{68},\;_{0.05}=0.232)$ and females $({\gamma}_1=.09<{\gamma}_{152},\;_{0.05}=0. 159)$. 12. The relation between daily urinary nitrogen excretion and sodium chloride excretion. The association between daily nitrogen excretion and sodium chloride excretion was positively significant for both sexes, males $({\gamma}_1=.31>{\gamma}\;_{68},\;_{0.05}=0.232)$ and females $({\gamma}_1=.36>{\gamma}_{-152},\;_{0.05}=0.159)$.
A total of 13,000 individuals of Dendrobium moniliforme (L.) Sw. artificially propagated in laboratories and greenhouses were restored in their natural habitat of Bogildo Island, Wandogun, in the southern part of Korea in June of 2013. The growing conditions of the individuals were monitored for two years. The parental individuals for the restoration were obtained from a wild population in southern Korea, from which seeds were produced via artificial crossings. These seeds were germinated and cultivated in growing media and two-year-old plants were then grown in greenhouse beds. The genetic diversity among the propagated individuals was confirmed by examining DNA sequences of five regions of the chloroplast genome and the nuclear ITS region. The diversity values were as high as the average values of natural populations. All propagated individuals were transplanted into two different sites on Bogildo by research teams with local residents and national park rangers. After restoration, we counted and measured the surviving individuals, vegetative propagated stems, and growth rates in June of both 2014 and 2015. There was no human interference, and 97% of the individuals survived. The number of propagules increased by 227% in two years. In contrast, the average length of the stems decreased during the period. In addition, different survival and propagation rates were recorded depending on the host plants and the restored sites. The shaded sides of rock cliffs and the bark of Quercus salicina showed the best propagation rates, followed by the bark of Camellia japonica. A few individuals of D. moniliforme successfully flowered, pollinated, and fruited after restoration. Overall, our monitoring data over two years indicate that the restored individuals were well adapted and vigorously propagated at the restored sites. In order to prevent human disturbance of the restored sites, a CCTV monitoring system powered by a solar panel was installed after the restoration. In addition, a human surveillance system is operated by national park rangers with local residents.
The present study was conducted to investigate smoking status and the relationship of smoking to hypertension and diseases on 1,504 subjects who were over 30-year-old age in Kyungsan Gun, Kyungpook province, during the period of 12 months from March 1978 to February 1979. The results obtained are summarized as follows: Of 1,504 subjects, 52.2 percent smoked. The percentage of males smoking showed 84.8 and the percentage of females was 30.7. There were no statistically significant differences between the rate of smoking and educational levels. Protestants demonstrated lower rates of smoking compared with other groups. Regarding the age started to smoke, 66.4 precent of male smokers and 16.9 percent of female smokers commenced smoking before the age of 19. In the regard to the average number of cigarettes smoked daily, 45.8 percent of male smokers consumed some 20 cigarettes and 24.1 percent of female smokers consumed some 10 cigarettes. 3.2 percent of male smellers smoked 40 or more cigarettes a day. Alcohol consumption was closely associated with smoking. 90.7 percent of male alcohol drinkers and 60.1 percent of female drinkers smoked. Cigarette smokers have higher rates of ailments than nonsmokers as a whole. The complaints of cough with sputum and shortness of breath revealed higher rates among smokers than among nonsmokers. Frequency of illnesses showed higher for smokers than for nonsmokers. Smokers were more likely than nonsmokers to suffer from chronic obstructive lung diseases such as chronic bronchitis, asthma, and emphysema. Abnormal systolic blood pressure (>160mmHg) and diastolic (>100) revealed significantly higher among smokers than among nonsmokers.
BACKGROUND: As improved LEDs (Light Emitting Diode) industry and decreased the price of LEDs in Korea, some farmers try to using the RED LEDs in green house and open field to increase the production of crop under bad weather condition. The aim of this study is to find out the effect of RED and FAR-RED LEDs lighting on the fruit quality of twelve-year old 'Hongro'/M.26 apple during night after sunset. METHODS AND RESULTS: FAR-RED (730nm, 2 and 4 hour) and RED (620nm, 2 and 4 hour) with 20 LED/PCB were treated in orchard for 16 weeks from June 10 to October 10 in 2009 and 2010 with control as an comparison. In our experiments, leaf weight was significantly higher in RED LEDs than control, tended to be decreased as times of FAR-RED lighting increased. Fruit weight was increased more in RED LEDs than control in 2009 and 2010, but decreased in FAR-RED lighting compared to control in 2010. Firmness and Hunter's a value of fruit were increased in FAR-RED lighting with 2 and 4 h than control. Soluble solid contents were higher in 2 h RED and 2, 4 h FAR-RED LEDs compared to control in 2009, there was no significant difference in 2010. Acid contents were no difference among the treatments. CONCLUSION(S): In our results, we found that RED LEDs was more helpful to increase the fruit weight and FAR-RED LEDs promote to be higher hunter a value of fruit skin. So, we thought that it is necessary to more study if mixed of RED and FAR-RED lighting is more helpful to promote fruit quality of 'Hongro' apple than single lighting of RED or FAR-RED LEDs respectively.

Objective : The purpose of this study is to investigate the epidemiology and clinical characteristics of herpes zoster in children and adolescents in Korea and to delineate the effects of varicella vaccine on the incidence of zoster and its complication. Methods : We evaluated the clinical records of 201 patients younger than 20 years admitted for herpes zoster at four hospitals located in Kyung-Gi provine during Jul. 1995 to Jun. 2005. Results : The admitted patients for herpes zoster have increased during the past 10 years. The effects of varicella vaccine on the incidence of herpes zoster remain inconclusive in this study. Only twelve percent of the study patients had underlying diseases. In 34(17%) of 201 patients, complications were confirmed during hospitalization. Of 34 patients, meningitis occurred most frequently. Irrespective of varicella vaccination, occurrence of complications was higher in patients who had experienced varicella previously(=overt varicella infection) than patients who had not(=subclinical varicella infection). In case of no previous varicella history, we found complications to be much lower in those who had received the varicella vaccine than those who had not. Conclusion : We cannot conclude whether the varicella vaccine has an effect on the increasing incidence of zoster. We can conclude that the subclinical varicella infection or vaccination for varicella might lead to a decreased incidence of zoster complications.
Background : Bronchial anthracofibrosis (BAF) is a dark black or brown pigmentation of multiple large bronchi associated with a fibrotic stenosis or obliteration that is incidentally found during a diagnostic bronchoscopy some reporters have suggested endobronchial tuberculosis or tuberculous lymphadenitis as a possible cause of BAF. However, some BAF patients do not have any medical history of tuberculosis. The aim of this study was to elucidate the clinical features of simple BAF patients, which were not associated with tuberculosis. Methods : We reviewed the patients' charts retrospectiely and interviewed all BAF patients who were followed up for 1 year or more. Among the 114 BAF patients, 43 patents (38 %) had no associated tuberculosis, cancer and pneumoconiosis. The clinical characteristics, radiological findings and associated pulmonary diseases of these patients were evaluated. Results : Most patients were non-smokers, old aged, housewifes who resided in a farming village. The common respiratory symptoms were dyspnea, cough and hemoptysis. The predominant X-ray findings were a multiple bronchial wall thickening(89%), bronchial narrowing or atelectasis (76%) and a mediastinal lymph node enlargement with/without calcification (78%). Pulmonary function test usually showed mild obstructive ventilatory abnormalities but no patient showed a restrictive ventilatory pattern and the patients were frequently affected with chronic bronchitis(51%), post-obstructive pneumonia(40%) and chronic asthma(4%). Conclusion : Because BAF is frequently associated with chronic bronchitis and obstructive pneumonia as well as tuberculosis, a careful clinical evaluation and accurate differential diagnosis is more essential than empirical anti-tuberculous medication.

Yield and ginsenoside contents of ginseng (Panax ginseng C. A. Meyer) is affected by light intensity and quality, and the color and the thickness of PE shading net when PE net is utilized for shading material. This study was carried out to investigate the effect of light quality on root yield and ginsenoside contents off-year-old ginseng by using polyethylene shading net with each blue and yellow color, Spectral irradiance under blue and yellow shading net showed the peak at 498 nm and 606 nm, respectively, which made distinct difference in light quality. Heat injury ratio of blue shading net was increased distinctly more than that of yellow shading net in summer season because of higher transmitted quantum (23%)and air temperature (0.3 $^{\circ}$C) in blue shading net than those of yellow shading net. Chlorophyll content and leaf area under yellow shading net were higher than those of blue shading net, and its heat injury ratio was lower than those of blue. These effects may led to 48% higher increase of root yield under yellow shading net than that under blue shading net. The content of total ginsenoside in taproot was not significantly differed between blue and yellow shading net, while the content in lateral and fine root was significantly increased in blue shading net compared to yellow shading net. PDM ratio of blue shading net showed more significant increase in lateral root than that of yellow shading net. All of Rb$_1$/Rg$_1$ ratio in three parts of root under blue shading net was higher than that of yellow shading net, but there were no significant increase in the ratio of lateral root.
The objective of this study was to establish an open-field experimental warming treatment and precipitation manipulation system to simulate climate change impact for Pinus densiflora seedlings based on a climate change scenario in Korea. Two-year-old seedlings were planted in a nursery in April, 2013. The air temperature of warmed plots (W) was set to increase by $3.0^{\circ}C$ compared to control plots (C) using infrared lamps from May, 2013. The three precipitation manipulation consisted of precipitation decrease using transparent panel (-30%; $P^-$), precipitation increase using pump and drip-irrigation (+30%; $P^+$) and precipitation control (0%; $P^0$). Initially, the air temperature was $2.2^{\circ}C$ higher in warmed plots than in control plots and later air temperature was maintained close to the target temperature of $3.0^{\circ}C$. The average soil temperature was $3.1^{\circ}C$ higher in warmed plots than in control plots. Also the average soil moisture content after the precipitation manipulation increased by 13.9% in $P^+W$ and decreased by 10.0% in $P^-W$ compared to $P^0W$, and increased by 23.7% in $P^+C$ and decreased by 7.6% in $P^-C$ compared to $P^0C$. It was confirmed that the open-field experimental warming and precipitation manipulation system was properly designed and operating.
