        This study was conducted to investigate of hepatoprotective effect of dandelion water extract (DWE) according to repeated administration of thioacetamide (TAA) induced hepatotoxicity in Spraque-Dawley rats. Thirty rats were randomly assigned to 5 groups; normal control, DWE-control, TAA-control (TAA injection during the feeding of normal diet), TAA&DWE600 (TAA repeated injection during the feeding of DWE 600 mg/kg BW), TAA&DWE1200 (TAA repeated injection during the feeding of DWE 1,200 mg/kg BW). Rats in DWE-control and TAA&DWE groups were treated with DWE (600 or 1,200 mg/kg BW daily) by gavage for 20 days (twice a day). All the rats in the TAA-control and TAA&DWE groups were repeated injection of TAA (100 mg/kg BW) into the abdominal cavity 3 days interval and 12 hrs later, all rats were sacrificed. At the same time, normal control and DWE-control groups were injected normal saline. In TAA&DWE groups, serum alanine and aspartate aminotransferase (ALT, AST) were significantly decreased and triglyceride (TG) synthesis was significantly increased compared to TAA group. As well as total billilubin and GGT were slightly decreased by the treatment of DWE. Lipid peroxidation (MDA) concentration was significantly decreased and hepatic GSH content was slightly or significantly increased in the TAA&DWE groups compared to TAA group. Hepatic antioxidative enzyme activities, such as GSH, GST, SOD and catalase were slightly or significantly elevated by the treatment of DWE. According to these results, When dandelion extract was long term supplied, it could be used as a potential protective material for a longer time liver damage by repeated adminstration of the TAA.

        ATP를 이용한 50인 미만 노인복지시설 급식위생관리 실태 조사와 조리 종사자의 위생관리 실천도 평가

        서선희 ( Sun Hee Seo ),문선진 ( Sun Jin Moon ),최정화 ( Jung Hwa Choi ) 대한영양사협회 2011 대한영양사협회 학술지 Vol.17 No.2

        The purpose of this study was to investigate food sanitation status in elderly welfare facilities and assess the performance of food sanitation practices. Twenty elderly welfare facilities out of 85 located in Seoul with a capacity of fewer than 50 persons participated. The food sanitation status of worktable, kitchen utensils (knives, cutting boards, ladles, spoons), and tableware and bowls were examined by ATP bioluminescence. The results found that the ATP value of knife was the highest. Those of ladles appeared relatively higher than others. Meanwhile, the tableware and bowls, although washed everyday after meals, had the lowest ATP value. This study also conducted a survey on the food sanitation practices of 32 cooking employees in the 20 facilities. Fifty-six percent were in their 40s, and 53% had graduated from high school. More than half (66%) of them had no certification of cooking. Half of the respondents had worked for at least 5 years in food service facilities, and had received food sanitation training. Among them, 31% said they applied food sanitation training while working, and 47% responded the training was very helpful. The foodservice employees demonstrated good food sanitation practices. The results show that food sanitation performance of the workers significantly differed according to their age, education level, total work experience in food service facilities, chef certification, and prior food sanitation experience.

        잎 절편의 재분화에 의한 참박 형질전환

        조송미(Cho, Song-Mi),문선진(Moon, Sun-Jin),정수진(Chung, Soo-Jin),김미성(Kim, Mi-Seong),김영철(Kim, Young-Cheol),양광열(Yang, Kwang-Yeol),최용수(Choi, Yong-Soo),Sapkota, Kumar,조백호(Cho, Baik-Ho),김광상(Kim, Kwang-Sang) 한국자원식물학회 2006 한국자원식물학회지 Vol.19 No.5

        수박의 대목으로 사용되고 있는 참박의 재분화조건을 확립함으로서 병저항성 형질전환 식물체를 얻어 보고자 본 실험을 실시하였다. 참박의 자엽을 잘라 재분화에 미치는 식물생장조절물질의 효과를 조사하였고 오이 galactinol synthase (CsGolS1) 유전자를 참박에 형질전환하였던 결과는 다음과 같다. 참박 신초의 재분화는 7일째 된 유묘의 자엽부위 중 전반부위에서 기장 높은 효율을 나타내었고, cytokinin으로 BA나 zeatin을 단용처리하는 것보다 옥신으로 IAA를 혼용처리하는 것이 신초 분화에 더 효과적이었다. 복합스트레스 내성 유전자인 오이 CsGolS1유전자를 pBI121 binary vector에 재조합하여 아그로박테리움을 이용, 참박에 형질전환하였던 결과, 형질전환체는 kanamycin이 첨가된 배지에서 생장하였고 PCR 및 Southern blot 분석에 의해 유식물체의 20% 정도가 형질전환체임을 확인할 수 있었다. In order to develop a disease-resistant root stock for the growth of watermelon, an efficient regeneration system of the gourd(Lagenaria leucantha Duch.) inbred line GO701-2 via organogenesis was established in this experiment. Using proximal parts of cotyledon explant excised from germinated seedling in vitro, maximum adventitious shoot formation (39%) was achieved on MS medium where cytokinin (BA) and auxin (IAA) were added at a concentration of 3mg/L and 0.1mg/L, respectively. Roots of the elongated shoots were successfully formed on MS medium without adding any plant growth regulators. The cucumber CsGolS1 gene known as a resistance gene against biotic and abiotic stresses, was constructed into the binary vector pBI121 under the control of CaMV 35S promoter. When the gene was introduced into the genome of gourd by Agrobacterium-mediated transformation, putative transgenic plants were obtained with the transformation efficiency of approximately 20 percent.

        Thioacetamide로 유발된 간 손상에 대한 Taraxacum officinale (Dandelion) 추출물의 효과

        조인영 ( In Young Cho ),마세령 ( Se Ryung Ma ),문선진 ( Sun Jin Moon ),유도현 ( Do Hyeon Yu ),신성식 ( Sung Shik Shin ),손창호 ( Chang Ho Son ),오기석 ( Ki Seok Oh ),허태영 ( Tai Young Hur ),정영훈 ( Young Hun Jung ),최창용 ( Chan 한국동물위생학회 2013 韓國家畜衛生學會誌 Vol.36 No.4

        The genus Taraxacum, known by the common name Dandelion, is a medicinal herb in the family Asteraceae. It has been traditionally used as a folk medicine for the treatment or prevention of various diseases due to its anti-inflammatory and anti-oxidative properties. In this study, we attempted to evaluate protective effects of Dandelion related with anti-oxidative activity to Thioacetamide (TAA)-induced liver damage. 36 rats were randomly assigned to six experimental groups:Control, Dandelion water extract (DWE), TAA, TAA&DWE 300, TAA&DWE 600, TAA&DWE 1,200 groups. Rats in DWE and TAA&DWE groups were pretreated with DWE (300, 600 or 1,200 mg/kg BW) by gavage for 7 days. All rats were treated intraperitoneally with TAA (200 mg/kg BW) or normal saline at 12 hours after last oral administration and sacrificed at 12 hours after last treatment. Levels of WBC and Neutrophil count were significantly decresed in TAA&DWE 1,200 group compared with that in TAA group (P <0.05). In TAA&DWE 600 and TAA&DWE 1,200 groups, serum AST, ALT, GGT levels were lower than TAA group (P<0.05). The serum TG level was significantly elevated in TAA&DWE groups compared with those in TAA group. Liver tissues from TAA group showed extensive histopathological changes, characterized by moderate or severe hepatocytes degeneration, inflammatory cell infiltration, and congestion. In the TAA&DWE group, The severity of histopathological lesions were decreased compared to those in the TAA group. The MDA concentration was significantly decreased and GSH content was significantly increased in the TAA&DWE 1,200 group compared to those in the TAA group. GR, CAT and GST activities in the TAA&DWE 1,200 group were significantly increased compared to those in the TAA group.
