Jae-Young Cha1,,Jin-Chul Park,Beong-Sam Jeon,Young-Choon Lee,Young-Su Cho 한국미생물학회 2004 The journal of microbiology Vol.42 No.1

The influence of feedstock amino acids, salt, carbon and nitrogen sources on glutathione production by Saccharomyces cerevisiae FF-8 was investigated. Glucose, yeast extract, KH2PO4, and L-cysteine were found to be suitable feedstock. Highest glutathione production was obtained after cultivation with shaking for 72 h in a medium containing glucose 3.0% (w/v), yeast extract 3.0%, KH2PO4 0.06% and L-cysteine 0.06%. The glutathione concentration achieved using this medium increased 2.27-fold to 204 mg/l compared to YM basal medium.

오로토산 유발 지방산의 간장 트리아실글리세롤 축적간 지방산 조성의 변화

차재영,김경숙,조영수 한국식품영양학회 1998 韓國食品營養學會誌 Vol.11 No.5

본 연구는 오르트산 투여가 흰쥐의 지방간 유발 형성과정에서 간장 및 혈청의 각 지질과 간세포의 지방산 조성에 대하여 경시적으로 함량 변화를 분석하였다. 그 결과 오로트산 투여 흰쥐의 간장 지질의 구성 지방산 중에서 리놀레산 (18:2, n-6)이 모든 각 지방질 중 가장 많이 증가하였다. 리놀레산은 간세포의 소포체 및 골지체의 트리아실글리세롤에서도 증가하였다. 이 지방산 패턴을 경시적으로 분석한 결과, 간장 트리아실글리세롤에서는 오로트산 투여 1일째부터 증가하고, 디아실글리세롤에서도 같은 결과를 나타냈다. 그러나 혈청 트리아실글리세롤에서는 오로트산 투여 1일째에서는 증가하였으나, 2일째부터는 증가율이 둔화되었고, 10일째에서는 대조군보다 저하하였다. 한편, 지방산 중에서 올레인산(18:1, n-9)은 간장 콜레스테릴 에스테르에서만 현저히 상승하였으나, 다른 것에서는 차이가 없었다. 간장 트리아실글리세롤, 디아실글리세롤, 콜레스테릴 에스테릴의 구성 지방산 중에서는 14:0, 16:0, 18:0의 포화지방산은 오르트산 투여로 저하하였고, 역으로 혈청 트리아실글리세롤에서는 이런 지방산이 증가하였다. 이러한 결과로부터, 오르트산 유발 지방간에 있어서 간장 트리아실글리세롤이 축적될 때, 간장지질의 구성 지방산 중에서 18:2의 비율이 현저하게 증가한바, 지방산의 대사 저해와, 간장에서 혈청으로 이행하는 경로가 저해되고 있는 것으로 나타났다. Dietary orotic acid is known to induce the fatty liver. Fatty acid profiles in the lipid fraction of the liver and the serum in rats fed with or without orotic acid diet were analyzed. In all the hepatic lipid fractions of rats fed on the supplemented orotic acid diet, there was a significant increase in linoleic acid. In addition, linoleic acid was also increased in the triacylglycerol faction of hepatic endoplasmic reticulum and the triacylglycerol and diacylglycerol fractions of hepatic Golgi apparatus of the orotic acid-feeding rats. In the time course study of the fatty acid profile in the hepatic triacylglycerol and diacylglycerol fractions, an increase of linoleic acid was observed similarly in the initial stages of orotic acid intake in the both fractions. However, linoleic acid in the serum triacylglycerol fraction of orotic acid-feeding rats increased from day 1, but it began to decrease the increment from day 2, resulting in the lower level of linoleic acid in the serum triacylglycerol fraction of orotic acid-feeding rats than that of rat fed a orotic acid-free diet after 10 days. Oleic acid (18:1) was increased in the only cholesteryl ester fraction of hepatic. However, oleic acid level in other fractions was not changed. The compositions of 14:0, 16:0 and 18:0 was reduced in the hepatic triacylglycerol, diacylglycerol and cholesteryl ester fractions by orotic acid-feeding. However, these saturated fatty acids were significantly increased in the serum triacylglycerol fraction. The orotic acid induced changes in linoleic acid level in hepatic triacylglycerol may be explained by the impaired fatty acid metabolism and limited excretion of this fatty acid from liver to serum.

Orotic acid 유발 지방간 rat와 mouse의 중성지질 대사

車載英,조영수 東亞大學校附設遺傳工學硏究所 1997 遺傳工學硏究 Vol.- No.4

Orotic acid 1% 투여에 의해 유발된 脂防肝 SD-계 rat와 kud : ddY mouse의 중성지질대사에 미치는 n-6계 지방산의 효과에 대하여 검토하였다. 그 결과 rat에 orotic acid무첨가 식이와 비교할때 1% orortic acid및 n-6계 PUFA(linoleic acid)가 함유된 반합성 식이 투여군에서 간장의 triglyceride함량은 유의적으로 증가하였고, 반면 혈청 triglyceride 함량은 감소하였다.이에 비해, mouse는 orotic acid 1% 함유식이 투여에 의해 간장triglyceride함량은 rat와 달리 증가하는 경향이었다. 중성지질 최종제한 단계 효소인 phosphatic acid phosphohydrolase의 활성은 triglyceride합성을 촉진시켰으며, orotic acid첨가 식이를 투여한 rat의 간장 cytosol및 microsome에서도 같은 경향이었다. 이러한 것으로부터 이 효소의 활성은 rat에 있어서 지방간 항진에 관여한다는 것이 강하게 시사되었다. Effects of 1% dietary orotic acid on triglyceride metabolism were examined in SD-rats and Kud : ddY mice. When rats were fed semisynthetic diet containing 1% orotic acid and n-6 polyunsaturated fatty acid(linoleic acid), the hepatic triglyceride content was increased significantly by about 3-fold and the serum triglyceride content was decreased compared with orotic acid-free diet. In contrast to rats which respond to orotic and consumption with increases in hepatic triglyceride content, mice did not so respond. The rats-limiting step in triglyceride synthesis is catalyzed by the enzyme phosphatic acid phosphohydrolase (EC 3.1.3.4) which is present in the liver cytosol and microsomes of rate fed orotic acid diet. This finding suggests that the activity of this enzyme may play a role in the fatty liver formation in rats.

차재영,김효정,전방실,박진철,옥민,조영수 한국응용생명화학회 2003 Applied Biological Chemistry (Appl Biol Chem) Vol.46 No.3

발효식품 시료로부터 분리된 세균을 DPPH(α,α¹-diphenyl-β-picrylhydrazyl) 전자공여능으로 항산화 활성을 측정하여 가장 활성이 강한 균주를 선별하여 형태학적, 생화학적, 생리학적 특성 및 16S rRNA 염기서열을 조사한 결과 Bacillus sp.으로 판명되어 FF-7로 명명하였다. DPPH 전자공여능법에 의한 Bacillus sp. FF-7이 생산하는 항산화물질의 최적 생산 배지조건은 탄소원 2% galactose와 질소원 1% tryptone 첨가였다. Bacillus sp. FF-7에 의해 생성된 항산화 물질의 활성을 DPPH 전자공여능, 흰쥐 각 조직 microsomal 실험계 및 linoleic acid 과 산화지질 실험계에서 malondialdehyde를 thiobarbituric acid(TBA)방법으로 측정하였다. 흰쥐 각 조직 microsomal 실험계에서 지질과산화에 대한 항산화 효과는 뇌(97.50%)>심장(79.95%)>신장(77.84%)>비장(77.47%)>고환(69.96%)>간장(62.45%) 순이였다. Linoleic acid의 과산화지질률 TBA법으로 측정한 결과 반응 4일째까지 억제 효과가 강하게 나타났으며, 동시에 대조구로 사용한 0.05% BHT 첨가구에서도 실험종료시까지 항산화 활성이 강하게 나타났다. The antioxidative activity of antioxidative substances produced from several bacterial strains isolated from fermented foods were tested by DPPH (α,α'-diphenyl-β-picrylhydrazyl) free radical scavenging activity. One of the strains showing the highest antioxidative activity was identified as Bacillus sp. based on the morphological, biochemical, physiological characteristics, and 165 rRNA sequence, and named FF-7. The molt optimal medium condition for the production of antioxidative substance from Bacillus sp. FF-7 was 2% galactose as carbon source and 1% tryptone as nitrogen source. The antioxidative substance produced from FF-7 in these cultural medium was also tested by in vitro experimental models, the peroxidation of linoleic acid and the peroxidation of rat tissues microsomes by using thiobarbituric acid (TBA) for assay of free rnalondialdehyde production. The antioxidative avtivity against lipid peroxidation of rat tissues microsomes was shown in the following order; brain 97.50% > heart 79.95% > kidney 77.84% > spleen 77.47% > testis 69.96% > liver 62.45%. The antioxidative substance produced from FF-7 on linoleic acid peroxidation by TBA method was effectively inhibited during four days, and 0.05% BHT(butylated hydroxytoluene) used comparative control was also effectively inhibited. Results showed that the highest antioxidative activity by DPPH method of antioxidative substance produced from Bacillus sp. FF-7 was obtained by supplementing 2% galactose as carbon source and 1% tryptone as nitrogen source in cultured medium, this substance effectively inhibited the formation of TBARS in brain microsome in vitro system and in linoleic acid peroxidation.

Objectives : The Symmetry, Ordering and Arranging Questionnaire (SOAQ) has been reported as a valid tool for the assessment of symmetry, ordering and arranging compulsive behaviors of patients with obsessive compulsive disorder. It was introduced by Radomsky and Rachman in 2004. The aim of this study was to assess the reliability, validity and psychometric properties of the Korean-version of the SOAQ (K-SOAQ). Methods : Two hundreds twenty eight under-graduate college students were enrolled in this study. They were assessed with K-SOAQ, Obsessive-Compulsive Inventory-Revised (OCI-R), Beck Depression Inventory (BDI) and Beck Anxiety Inventory (BAI). Statistical analysis was done using calculation of Cronbach’s alpha, Spearman Correlation Coefficient and Principal Components Analysis. Results : There were no significant differences in sex, education, and total scores of BDI and BAI. The Cronbach’s alpha coefficient of K-SOAQ was high, Cronbach’s α=0.96. There was strong evidence for a one-factor solution, accounting for 60.3% of the variance. Convergent validity was examined through correlations between the SOAQ and the OCI-R (r=0.61). Divergent validity was examined through correlations between the SOAQ and two self report measures; BDI (r=0.12) and BAI (r=0.19). Conclusion : The K-SOAQ showed good reliability and validity for the assessment of severity of compulsive characteristics regarding symmetry, ordering and arranging. The K-SOAQ is a useful instrument for assessing compulsive symptoms related with symmetry, ordering and arranging in Korea.
