We investigated microbial populations of an upland and cultivated Codonopsis lanceolata. The microbial populations from both types of soils were also investigated. There were more than 10 microorganisms existed in upland than cultivated one. The total viable cell counts of C. lanceolata from upland and cultivated one, especially in the upper zone, were 9.7×10^(6) CFU/g and 4.2×10^(6) CFU/g, respectively. As a results, upper parts of C. lanceolata in upland were considered to harbour approximately more than 2.3 fold higher microorganisms than in cultivated one. However, the total viable cell counts between the two soil habitat, that is, 1.2×10^(7) CFU/g from upland and 1.0×10^(7) CFU/g from cultivated, were not significantly different. We also examined the unique flavor producing microorganisms in the soil extract broth including 25% C. lanceolata extract. One microorganism was detected in upper pars of C. lanceolata and upland soil. No. 6, microorganism causing the characteristic flavor of C. lanceolata was confirmed as Actinomyces by microscopy.

지리적 위치에 따라 소아들에 있어서 혈중 연농도에 차이가 있는지의 여부와 소아들의 혈중 연농도의 참고치 계산을 위한 기초자료를 얻기 위하여 6-8세의 도심지역 거주 소아 102명과 교외지역 거주 86명, 총 188명을 대상으로 조사하여 다음과 같은 결과를 얻었다. 1. 전체 소아들의 평균혈중 연농도는 산술평균이 7.24, 기하평균이 6.92 ㎍/100㎖이었으며 남자가 여자보다 통계적으로 유의하게 더 높았다(p<0.05). 2. 도심지역과 교외지역 거주 소아들의 혈중 연농도는 도심지역거주 소아가 남, 녀 모두에서 교외지역 거주 소아보다 통계적으로 유의하게 더 높았다(p<0.05). 3. 혈중 연농도에 따른 분포에서는 <5 ㎍/100㎖군에 조사대상자 188명의 17.02%가 분포되었고 도심지역(5.88%)보다 교외지역(30.23%)에서 더 많은 분포를 보였으며, 10 ㎍/100㎖이상 군에는 전체 소아의 12.23%가 분포하고 있었으며, 도심지역(20.59%)이 교외지역(2.33%)보다 더 많이 분포하고 있었다. 이상의 결과에서 볼 때 도심지역 거주 소아들에 대한 연폭로의 관리대책이 시급히 마련되어야 할 것으로 판단된다. The authors conducted this study to evaluate some differences in blood lead levels between inner-city and suburban children and obtain the basic data of the reference value of the blood lead concentrations in children. The subjects were composed of 102 children residing in inner-city and 86 children in suburban. Their age range were 6 to 8 years old and the obtained results were as follows; 1. The arithmetic means of the blood lead level in male and female, male, and female children were 7.24, 7.40, 7.08 ㎍/100㎖, and geometric means were 6.92, 7.08, 6.76㎍/100㎖, respectively. 2. The children residing in inner-city had the higher blood lead levels both male and female than suburban children with statistical significance(p<0.05) 3. Seventeen percent of the total subjects had lead concentrations < 5 ㎍/100㎖, and 5.88% of inner-city children and 30.23% of suburban children had this lead values. But in ≥10㎍/100㎖ group, the inner-city children(20.39%) were more distributed than suburban children(2.33%), and 12.33% of total subjects had this lead values.

Eosinophilic granulomatosis with polyangiitis (EGPA), which was previously called the Churg-Strauss syndrome, is an ANCA associated vasculitis, accompanied by asthma, hypereosinophilia, nonfi xed pulmonary infi ltrates, and sinusitis. Peripheral neuropathy is common in patients with EGPA. However, a few cases of EGPA with CNS involvement have been reported. A 47-year-old female was referred for right side weakness and posterior neck pain. She was diagnosed as EGPA with subarachnoid hemorrhage and mononeuritis multiplex. She was effectively treated with a high dose glucocorticoid, cyclophosphamide and intravenous immunoglobulin (IVIG). EGPA with CNS involvement is uncommon and it causes signifi cant morbidity and mortality. Therefore more rapid and accurate diagnostic evaluation may be required. EGPA should be considered while patients have neurological symptoms and hypereosinophilia.

A new syndrome named Normal Weight Obesity (NWO) has attracted much attention in obesity-related researches. NWO i s a normal B ody Mass I ndex (BMI) a ssociated with a l arge p roportion of % Body Fat(%BF). Previously, NWO was known as a problem associated with aging. However, recent years, it has appeared to many young women. Lookism is the largest cause. Lookism has been shown to spread in our society, excessive diet and irregulareating habits, was supposed to lead to results, such as body weight regulation of in an unusual way. The purpose of this study was to find the prevalence of NWO, and the eating and exercise behaviors of Korean university women. We studied 422 volunteers, 138 were interviewed. 140 university women had bioelectrical impedance analysis to estimate body composition. All the participants filled out the Questionnaire that eating and exercise behavior. The percentage of Standard was 48.6%, NWO was 32.0% and Obesity is 10%. Interestingly, significant differences between Standard and NOW in exercise behaviors (p<.001). But, there were no significantly different in eating behaviors (p<.001). In contrast, both of eating and exercise behaviors were significantly different between Standard and Obesity (p<.01). As expected, NWO and Obesity were significant differences eating Behavior only (p<.05). The findings of the study represent important directions for the future planning of intervention programs designed to prevent NWO. Exercise interventions are warranted to prevent NWO in university women.

Objectives:Metadoxine is known to have accelerated the metabolism of alcohol in previous studies with Caucasian subjects. The purpose of this study was to evaluate the effects of metadoxine on alcohol pharmacokinetics and pharmacodynamics in normal Korean adults according to the low-Km aldehyde dehydrogenase (ALDH2) genotypes. Methods:Twenty healthy male volunteers (half with active ALDH2*1/*1:active group, the other with inactive ALDH2*1/*2:inactive group) were selected by genotyping. In a double-blind, counterbalanced design, each subject ingested 0.5 g of alcohol per kg of body weight with pretreatment of metadoxine or placebo on 2 separate occasions. Blood alcohol concentration by breathanalyzer (BrAC), vital signs, negative physiological responses and performance function using a battery of tests (critical flicker fusion threshold:CFFT, choice reaction time:CRT, compensatory tracking task:CTT and digit-symbol substitution:DSS) were measured at baseline and repeatedly over a 3-hour period after intake of alcohol. Results:Among the pharmacokinetic parameters, Vmax and Km were significantly increased with pretreatment of metadoxine in both the active and inactive ALDH2 groups, but the ratio of Vmax/Km was decreased. In terms of pharmacodynamics, the pretreatment of metadoxine produced a significant improvement of performance such as CFFT and DSS in the active ALDH2 group, but did not in the inactive ALDH2 group. Conclusions:It may be concluded that metadoxine has little effect on alcohol metabolism in both groups with respect to pharmacokinetics on the basis of BrAC. The pharmacodynamic results, however, indicated that metadoxine might be partially effective in counteracting the impairing effects of alcohol on the performance in the active ALDH2 group.

premised upon identifying personal factors (e.g. demographics or psychographics) underlyingthe purchase decision. On a broader scope, however, consumer behavior is shaped by cultural andsocial factors, and our understanding would be incomplete without these considerations. To thisend, this study sets out to provide an integrative framework on durable consumption. Specifically,the proposed framework explores whether cultural differences do exist in the perception of aselected durable (e.g. automobile) on the symbolic/utilitarian dimension, which in turn, may affectthe length of the replacement cycle, likelihood of upgrading to a higher status model, as well as,van,pickup truck). Applying a multinomial logit model to Korean and US automobile transactiondata, the finding reveal that Korean consumers tend to have shorter replacement cycles, engage inmore upgrades but are less likely to change the product-type than American consumers.vers of the differences inperception and behavior are put forward. Managerial implications and directions for futureresearch are also discussed.
