Five kinds of Korean red pepper-pinkish, perfect, cucumber, blue, and ground cherry-were used, respectively, to analyze the contents of Capsaicin and Dihydrocapsaicin. The comparative analysis was performed separately in the seed removed red pepper and the seed included red pepper by HPLC. Among the seed removed pepper, the results for the content of Capsaicin were shown as follows: ground cherry(2204.0ppm) > pinkish(1324.9ppm) > blue(906.7ppm) > cucumber (77.2ppm) > perfect(12.9ppm), and the results for the content of Dihydrocapsaicin were shown as follows: ground cherry (1004.8ppm) > pinkish(248.3ppm) > blue(165.7ppm) > cucumber(13.9ppm) > perfect(0.0ppm). Among the seed included red pepper, the results for the content of Capsaicin were shown as follows: ground cherry(2190.lppm) > pinkish(1324.4ppm) > blue (919.9ppm) > cucumber(79.5ppm) > perfect(11.7ppm), and the results for the content of Dihydrocapsaicin were shown as follows: ground cherry(1017.4ppm) > pinkish(270.6ppm) > blue(189.0ppm) > cucumber(39.4ppm) > perfect(0.0ppm). Overall results suggest that in the contents of Capsaicin and Dihydrocapsaicin, the seed removed pepper and the seed included red pepper both were decreased in the order of ground cherry > pinkish > blue > cucumber > perfect, and this order is proportional to the strength of hot taste of red pepper.

토양으로부터 분리한 B. subtilis를 有機物이 施用된 토양에 還元 接種하여 有機物 種類에 따른 B. subtilis의 토양중에서 適應·定着性 및 B.subtilis가 다른 土壤微生物相에 미치는 영향을 經時的으로 조사하였다. 또한 有機物이 시용된 토양중에서 B,subtilis와 植物 病原菌인 F. oxysporum을 동시에 接種하여 상호간의 拮抗的 關係를 검토한 결과는 다음과 같다. 1) B. subtilis菌數는 對照區에서보다 B. subtilis 接種區에서 增加를 보였고 단지 볏짚 및 크로버만을 사용한 區에서보다 볏짚 및 크로버 施用區에 B. subtilis를 접종한 區가 약 2배 정도 B. subtilis菌數의 증가를 보였다. 특히 B.subtilis를 有機物 施用區에 접종했을 때 볏짚 시용구가 크로버 시용구에서보다 B. subtilis菌數가 약 3배 정도 현저하게 증가하였다. 2) 細菌과 絲狀菌數는 대조구보다 B.subtilis 接種區에서 각각 23% 및 20%씩 감소하였으므로 또한 크로버 시용구에서보다 크로버+B. subtilis 접종구에서도 각각 33% 및 16%씩 감소하였고, 볏짚 시용구에서는 볏짚+B. subtilis 접종구에서 각각 29% 및 32%씩 감소경향을 나타내었다. 3) 胞子形成菌數는 대조구보다 B. subtilis 접종구에서 약 10배 정도 증가하였으며 단지 有機物만을 시용한 區보다도 크로버+B. subtilis 접종구와 +B. subtilis 접종구에서 각각 2배, 4배 정도의 증가경향을 보였다. 또한 gram(-)細菌도 胞子形成菌數와 비슷한 경향을 나타내었고, B. subtilis接種이 그람 음성 세균수의 변동에는 영향을 미치지 않았다. 4) F. oxysporum의 菌數는 크로버 시용구에서보다 크로버+F. oxysporum 접종구에서 25배 정도 증가하였으나 크로버+B. subtilis 접종구에서는 크로버+F. oxysporum 접종구보다 약 5배 정도의 감소경향을 나타내었다. 또한 F. oxysporum菌數는 볏짚+F. oxysporum區에서 볏짚 單獨施用區보다 3배 정도 증가하였으나 볏짚+B. subtilis+F. oxysporum접종구는 볏짚+F. oxysporum접종구보다 F. oxysporum의 數가 약 17배 정도 감소경향을 나타내었다. 더욱이 F. oxysporum菌數는 크로버+B. subtilis+F. oxysporum접종구보다 볏짚+B. subtilis+F. oxysporum접종구에서 약 40배 정도의 감소경향을 나타내었다. 5) 크로버 시용구의 토양 pH는 약 ph 9에 이르러 토양 ph가 alkali화되었으며 볏짚시용구의 토양 ph는 큰 변화 없이 약산성을 유지하였다. This study has been conducted to investigate the adaptation of Bacillus subtilis to the soil and the antagonistic interaction between B. subtilis and pathogen Fusarium oxysporum as well as the periodic change of soil microflora when B. subtilis was inoculated to the soil treated with organic matters. Some results obtained from this study are as follows : 1) The number of B. subtilis was more increased about 6 times in the plot inoculated with B.subtilis than in control plot. It was relatively double in the organic matter+ B. subtilis plot than in the only organic matter plot. B. subtilis was particuraly increased about 3 times in the straw +B. subtilis plot, compared with the clover +B. subtilis plot. 2) The number of total bacteria and fungi was decreased by 23% and 20% in the plot inoculated with B.subtilis respectively than in control plot. It was not only decreased by 33% and 16% in the clover+B. subtilis plot respectively than in the only clover plot but it was also decreased by 29% and 32% in the straw+B. subtilis plot respectively than in the only straw plot. 3) The number of spore-forming bacteria was increased about 10 times in the plot inoculated with B.subtilis than in the control plot. It was also increased 2 times and 4 times in the clover+B.subtilis plot and in the straw+B. subtilis plot respectively than in each organic matter plot. The number of gram-negative bacteria and the spore-forming bacteria were slightly increased in all the plot inoculated with B. subtilis. 4) The number of F. oxysporum was increased about 25 times in the clover+ F. oxysporum plot than in the only clover plot. But it was decreased about 5 times in the clover+B.subtilis+ F. oxysporum plot than in the clover +F. oxysporum plot. Furthermore, F. oxysporum was remarkably decreased about 40times in the straw+B. subtilis+ F. oxysporum plot than in the clover+b. subtilis+ F. oxysporum plot. It occured that B. subtilis had inhibited the growth of pathogen F. oxysporum when B. subtilis was inoculation to the soil treated with straw. 5) Soil pH was changed to pH 9 in the plot treated with clover to become the alkalification of experimental soil. Meanwhile it was not changed in the plot treated with straw.

이유상,김형배,한진희,채영규,이정식,이혜순,주연호,김형섭,최인근,양병환 大韓神經精神醫學會 1999 신경정신의학 Vol.38 No.6

연구목적: Neurotensin(NT)은 NT수용체와 결합하여 그 효과를 나타내는 neuromodulator 혹은 neurotransmitter로서 대뇌에서 도파민의 분비를 조절하는데 중요한 역할을 한다. 근래의 연구에 의하면 NT와 그 수용체는 대뇌에서 항정신병 약물의 효과를 매개하는 것으로 생각되고 있으며 약물치료를 받지 않은 정신분열병 환자의 뇌척수액에서 NT의 양이 적으로 보고되고 있어 이들은 정신분열병과 깊은 관련을 가지고 있을 것으로 추정된다. 최근 NT수용체의 유전자의 3`인접영역에서 정보가치가 높은 4 염기반복 다형성이 발견되어 이를 유전 표지자로 하여 정신분열병과의 연합을 알아보았다. 방 법: 서로 혈연관계에 있지 않은 정신분열병 환자 120명(남자 91명, 여자 29명)과 정상 대조군 106명(남자 84명, 여자 22명)을 대상으로 하였다. PANSS를 사용하여 양성 및 음성을 알아보았다. 말초혈액에서 DNA를 분리한 후에 중합효소연쇄반응을 사용하여 3`인접영역에 있는 4 염기 반복 다형성을 증폭하였고 silver staining한 후에 유전자형을 관찰하였다. chi-square 검증과 Bonferroni`s correction을 사용하여 환자군과 정상 대조군간의 대립유전자 빈도의 차이를 알아보았다. 또한 양성 및 음성 환자군으로 나누어 차이를 알아보았다. 결 과: 총 23개의 대립유전자가 관찰되었으며, 399bp의 대립유전자(A10)의 빈도가 환자군보다 정상대조군에서 통계적으로 유의하게 높았다(χ²=16.49, df=1, p<0.001). 음성 정신분열병 환자군과 정상대조군 사이의 비교에서는 정상대조군의 A10의 빈도가 환자군보다 유의하게 높았다(χ²=21.33, df=1, p<0.001). 성별 비교에서 남자 정신분열병 환자군은 대조군에 비하여 A10의 분포가 유의하게 적었다. (χ²=13.71, df=1, p<0.001) 결 론: NT 수용체 유전자와 정신분열병사이에 음성연합이 관찰되었다. NT 수용체 유전자가 일부 정신분열병의 발병과정에서 확실하지는 않지만 어떤 종류의 보호기능을 할 수도 있다는 것을 암시한다. Objectives: Neurotensin(NT), of which functions are evoked by its interaction with neurotensin receptors(NTR), coexists with mesolimbic dopamine and regulates endogenous dopamine release. Recent studies have shown that NT with NTR exerts neuroleptic-like activity within the central nervous system and may play an important role in the pathogenesis and in the treatment of schizophrenia. We have examined the gentic association between schizophrenia and tetranucleotide repeat polymorphism in the 3-flanking region of the NTR gene to investigate the possible contribution of the NTR gene to the schizophrenia susceptibility. Methods: Among 23 alleles identified, the subjects were 120 patients(male 91, female 29)with schizophrenia and 106 normal healthy controls(male 84, female 22). They were unrelated native Korean. PANSS was used to determine positive or negative subgroup in the schizophrenic patients. Using polymerase chain reaction and polyacrylamide gel electrophoresis, tetranucleotide repeat polymorphism(CCTT and CTT) in the 3`-flanking region of NTR gene was observed. For a comparison of NTR gene`s allelic frequencies between patients with schizophrenia and normal healthy controls, chi-square test and Bonferroni`s correction was performed. Results: The frequency of A10 allele(base pair size=399)was significantly higher in normal healthy controls than schizophrenia(χ²=16.4902, df=1, p<.000). In the comparison between schizophrenic patients with negative symptoms and normal controls, the frequency of A10 allele was significantly higher in normal healthy control subjects than patients with schizophrenia(χ²=21.33, df=1, p<0.001). In the case of male, the frequency of A10 allele of schizophrenia was significantly higher than normal controls(χ²=13.71, df=1, p<0.001). Conclusions: NTR gene was negatively associated with schizophrenia. NTR gene`s tetranucleotide repeat polymorphism may provide some protective function against schizophrenia.

<B>Background</B><P> Whether the etiology of potential small-bowel bleeding depends on the age and gender of the patient is not yet fully understood. </P><B>Methods</B><P> A total of 1953 patients who underwent video capsule endoscopy (VCE) to evaluate potential small-bowel bleeding and were registered in the Capsule Endoscopy Nationwide Database Registry from 2003 to 2014 were eligible for this study. VCE findings and the etiology of small-bowel bleeding were analyzed by age and gender. </P><B>Results</B><P> The diagnostic yield of VCE was 48.4% (95% CI: 46.2%-50.6%) and the diagnosis rate of etiology of potential small-bowel bleeding was 61.4% (95% CI: 59.2%-63.6%). The etiology of potential small-bowel bleeding depends on the age and gender of the patient. Crohn's disease and small-bowel diverticular diseases were more prevalent etiology of potential small-bowel bleeding in the young adults group (@@<@@ 40 years) whereas angiodysplasia was revealed to be a most common etiology in elderly group (≥ 60 years), reaching statistical significance ( p@@<@@0.00152) by Bonferroni correction. </P><B>Conclusions</B><P> The etiology of potential small-bowel bleeding depends on the age of the patient. Thus, an individualized lesion-specific diagnostic approach based on age might be needed for patients with potential small-bowel bleeding. </P>

The main purpose of the present study is to develop a measure of children`s ballet service quality (CBSQ) scale by identifying underlying factors and testing external validities of the scale. Respondents of this study consists of 631 parents whose children were participating a ballet program. Through a series of confirmatory factor analyses, this study confirmed that the children`s ballet service quality scale produced reliable and consistent factorial structures. The results supported the construct validity of the scale. Two analyses are undertaken to determine whether the CBSQ scale is a measure of a redundant measure of an existing construct. First, the present study tests convergent validity that the CBSQ scale was correlated with measures of individual differences, which should be correlated with. The CBSQ scale shows significant correlations with customer satisfaction and customer loyalty, suggesting the CBSQ scale has convergent validity. Second, this study then assesses discriminant validity that the CBSQ scale yields measurements that are statistically distinguishable from individual differences (i.e., customer satisfaction and customer loyalty). Through discriminant validity test, the present study verifies that CBSQ scale is not redundantly measure any of individual difference constructs and is statistically distinguishable from the closely correlated constructs. In conclusion, the present study represents an initial step toward developing and testing a new scale to measure children`s ballet service quality.
