  • Lactobacillus reuteri는 사람과 동물의 장관 내에 존재하는 유산균의 일종으로서 혐기적 조건에서 glycerol을 대사하여 항균 물질인 루테린을 생산한다. 본 연구의 목적은 고정화된 L. reuteri를 이용하여 회분식 또는 연속식 생산 공정을 이용하여 루테린 생산의 반응 조건을 조사하는데 있었다. Agarose를 사용하여 고정화된 L. reuteri는 250mM glycerol과 반응시켜 루테린을 생산하였다. Agarose 농도를 0.5%로 조정한 회분식 생산 공정에서는 약 36시간 동안 루테린 생산이 지속되었고 시간 경과에 따라 루테린의 생산이 점차 감소하였다. 연속식 공정에서는 고정화 균이 현탁세포에 비하여 루테린 생산 시간이 약 2배 정도 연장되었으며 총 루테린의 생산 또한 502mM로 현탁 세포에 비하여 약 1.5배 증가하였다. 본 연구의 결과는 고정화 세포를 이용한 루테린 생산의 증가 가능성을 제시하였다.

  • The halophilic enterobacteria, Enterobacteria cancerogenus, was isolated from the intestines of the fusiform fish (Trachurus japonicus) to yield a protein-like material termed PLM-f74. PLM-f74 was characterized by strong inhibition ratios to angiogenesis (82.8% at the concentration of $18.5{\mu}g/ml$) and elevated antioxidative capacities with low toxicity. The PLM-f74 is a glycoprotein comprised of saccharides and amino acids. PLM-f74 inhibited cell adhesion that non-activated U937 monocytic cell adhesion to HUVECs activated with $IL-1{\beta}$ by 78.0%, and the adherence of U937 cells treated with the PLM-f74 and stimulated with $IL-1{\beta}$ to unstimulated HUVECs decreased by 102%. When both cell types were pretreated with PLM-f74, the adhesion of U937 cells to $IL-1{\beta}$-stimulated HUVECs was completely suppressed by 121% at a concentration of $18.5{\mu}g/ml$. PLM-f74 blocked signal pathways from VEGFR2, PI3K, ${\beta}$-catenin, and VE-cadherin to NF-kB, based on western bolt analysis. It also inhibited IL-l-stimulated HUVEC expression of the adhesion molecules, ICAM-l by 40%, VCAM-l by 60%, and E-selectin by 70% at the same concentration noted above. New anti-angiogenic and anti-cell adhesion materials showing elevated antioxidative capacities, and non-toxicity may be expected from these results.

  • "Uihakdokseogi(醫學讀書記)" is a casual work which mentions Ujaekyeong(尤在涇)'s thoughts on various problems found through extensive studying or in practice. The book does not focus on a single topic, thus the spectrum of the work is broad and is filled with problems which would interest most medical professionals. The major contents of the first volume of "Uihakdokseogi(醫學讀書記)" include differences of view on health preservation, the Five Circuit Phases[五運] and Six Atmospheric Influences[六氣], diseases, and the "Naegyeong(內經)", mentions on errors in transcription , and the gap between certain contents in "Yeongchu(靈樞)" and "Somun(素問)". U[尤在涇] asserts that Eum and Yang(陰陽) in a human should be in harmony as is the Gi(氣) of the sky and earth[天地] is, and that one should live according to the Gi(氣) of the four seasons to live a healthy life. He does not vary largely from the context of other writers on the matter of the Five Circuit Phases [五運] and Six Atmospheric Influences[六氣], and focuses on the concepts of predominant Gi[主氣], guest Gi[客氣], corresponding years[天符] , correlating years[歲會], and Taeeul corresponding years[太乙天符]. He mentions causes, symptoms, and treatments of various diseases such as cough due to asthenia of the viscera, stagnation of Yang(陽), stagnation of Eum(陰), abscess of the stomach, hard abscess of the intestines, upper emaciation, edema of the limbs, inability to raise the limbs, broken thigh, turbid fluid, inversion of Gi(氣) flow, sudden onset of fainting with cold extremities, diarrhea due to disorder of Gi(氣), and malaria. U[尤在涇] also points out faults of "Classic of Acupuncture and Moxibustion[甲乙經]" in the understanding of "Naegyeong(內經)".

  • Nitrate in edible vegetables is converted to nitrite by nitrate reductase(NR) and/or bacteria in intestines. Nitrite and amino, in the intestine of some animals and human, bind to form nitrosamine, which is toxic and known as carcinogen. This study was carried out to examine the effect of added chlorides and their concentrations on growth, yield and nitrate content in leaf lettuce plants in hydroponics. Seeds of lettuce cv, "Samsunjokchukmyon" were planted on April 29, and seedlings were planted on June 2, and were cultured until July 5 in 1998. KCI and CaCl₂ were used as chloride source and their concentrations were 1, 2 and 4 me/L, respectively, in the lettuce standard nutrient solution for National Horticultural Research Institute(NHRI). Completely randomized design with 3 replications was used. Nitrate content and NR activity were measured 2 and 5 weeks after planting(WAP). The obtained results were summarized as the follows : Leaf weight per plant was difference from harvest dates and treatments, but total leaf weight was not significantly different among treatments. Number of leaves was higher in KCI 2 me/L, CaCl₂1 me/L and control at 2 WAP than the others, and was higher in KCI 1 me/L, and control at 3 WAP than others, and was higher in control at 5 WAP. Total number of harvested leaves was the highest in control with 14, which followed by KCI 2 me/L and CaCl₂1 me/L. Nitrate content was decreased by addition of chloride in nutrient solution. Nitrate content in the 3rd and 9th leaves was significantly decreased. NR activity was higher in control and CaCl₂ addition treatments, while KCI addition treatments reduced NR activity. However, no direct relationship with nitrate was observed. Growth characteristics such leaf length and leaf width were not significantly influenced by chloride addition.

  • In the past, antibiotics and antimicrobial substances have been used for the purpose of promoting the growth of livestock or treating livestock, but various problems such as the presence of livestock products or resistant bacteria have emerged. Recently, regulations on the use of antibiotics have been strengthened worldwide, and probiotics are attracting attention as an alternative. Probiotic microorganisms have already been used for human use, such as intestinal abnormal fermentation, diarrhea, and indigestion. In livestock, beneficial microorganisms are increasing in use for the purpose of improving productivity, such as promoting livestock development and preventing diarrhea. Therefore, it is advisable to understand livestock probiotics in deeper and think about effective uses. The role of probiotics in the livestock sector is made with microorganisms themselves, so it is a substance that promotes livestock growth and improves feed efficiency by settling in the intestines of livestock, suppressing the growth of other harmful microorganisms, helping digestion and absorption of ingested feed, and helping to synthesize other nutrients. There is a need for a probiotic that suppresses intestinal bacteria by supplying probiotics used as a means to minimize the effects of stress in livestock management, thereby suppressing disease outbreaks by maintaining beneficial microorganisms and suppressing pathogenic microorganisms. The purpose of this paper is to develop a brand of feed additive probiotics to improve health conditions due to increased feed intake, improve the efficiency of use of feed nutrients, inhibit the decomposition and production of toxic substances, increase immunity, reduce odor in livestock, and improve the environment. We investigated and analyzed feed additive probiotics already on the market, and developed the naming and logo of suitable feed additive probiotic brands in livestock. We hoped that the newly developed product will be used in the field and help solve problems in the livestock field.

  • In the Far-Eastern traditional medicine, Oi[Energy] implies a wide range of meaning and is emphasized. There is nothing that is not related to this Qi, as seen in physiology, pathology, the relationship between human body and nature, the movements of intestines and gyeongnak[energy networks], the process of outbreak and change of illness, remedial laws, the features and effects of drugs, and so on. Accordingly, Nei Jing also says, 'every sickness arises from OL' The Qi has multi-meanings, and each of lots Of past physicians researched and analyzed it in different perspective, thus making the Qi-theories much richer. Still. there were not so many physicians who discussed the theme of Daqi. The denomination of Daqi is seen in Nei Jing and Jin Gui Yao Lue, and the physicians like Yu Chang in Ming dynasty and Zhang Xi Chun in Cheng dynasty, etc. applied and utilized Daqi by exploring its functional actions for human life and associating it with clinical practices. Yu Chang said that Daqi is Xiong Zong Yangqi[Positive Energy in Breast] governing every Qi, and that if this Qi is full, it spreads through body and protects the body from sickness, and vice versa. Summarizing his researches on the Daqi in Jin Gui Yao Lue and on the opinions of Yu Chang as well as his experiences, Chang Xi Chun maintained that the Qi accumulated in breast must be named Daqi, which constitutes the contents of Zongqi[Chief Energy] mentioned in Nei Jing. Once the Qi is vacant, breathing is not smooth, whole body is enervated, spirit becomes dim, thinking ability falls drastically. Furthermore, if the Qi is extremely vacant or more worsens, breathing stops. And he prescribed the medicines including Sheng Xian Tang as remedies against the symptom of Daqi XiaXian[Fall in Great Energy]. The recognitions of Daqi by Yu Chang and Zhang Xi Chun are consistent with each other. At any rate, their theories and prescriptions may be high in practical value in contemporary clinics.

  • 본 연구에서는 김치에서 분리한 우점유산균인 Lactobacillus plantarum KCCM 11352P(LPpnu)와 Leuconostoc mesenteroides KCCM 11353P(LMpnu)의 프로바이오틱 효과를 프로바이오틱 효과가 높기로 잘 알려진 Lactobacillus rhamnosus GG(LRgg)의 효능과 비교하여 확인하였다. 그 결과 LPpnu는 Lab. rhamnosus GG(LRgg)보다 프로바이오틱 효과가 더 뛰어났으며, LMpnu 또한 LRgg와 거의 유사한 수준의 효능을 나타냈다. LPpnu와 LMpnu는 모두 내산, 내담즙성, 장 부착능, 열 안정성의 프로바이오틱의 기본 특성을 가지고 있었으며, 특히 LPpnu는 가장 높은 프로바이오틱 효과를 나타냈다. 또한 LMpnu 및 LRgg와 비교했을 때 LPpnu는 DPPH radical과 hydroxyl radical 소거능 측정에서 더 높은 항산화능을 보였고, Bcl-2 유전자 발현억제와 Bax 유전자 발현 증가를 통해 apoptosis를 유도함으로써 HT-29 human colon cancer cell에서 높은 암세포 성장 저해 효과를 나타냈다. 이를 통해 김치유래 LPpnu와 LMpnu는 프로바이오틱으로서 이용 가능성이 충분하다고 판단되며, 특히 LPpnu는 항산화 및 항암 활성에 뛰어난 효능을 나타내었기에 중요한 프로바이오틱 균주라고 하겠다.

  • Lactobacillus 균주들의 에탄올과 acetaldehyde의 대사 가능성을 시험관내 및 생체내에서 시험하였다. ADH와 ALDH 활성은 L. brevis 균주들이 다른 Lactobacillus 균주들과 비교하여 높게 나타났으며, 특히 L. brevis HY7401은 가장 높은 ADH와 ALDH 활성을 나타냈다. L. brevis HY7401$(10^9\;cfu/mL)$을 2주간 하루에 1 mL씩 쥐에게 급여한 후 시험 14일째에 에탄올(4g/kg BW)을 경구투여하고 혈중 에탄올 양을 측정한 결과, L. brevis HY7401 급여에 의해 혈중 에탄올 수준이 대조구에 비해 유의적으로 감소하는 것으로 나타났다. 에탄올 투여 6시간후의 혈중 에탄올 양이 각각 $1,195{\pm}92.9$(대조군) 그리고 $454{\pm}150mg/L$(HY7401군)으로 나타났다. 또한 L. brevis HY7401 급여한 군에서 소장내 에탄올 농도가 대조구와 비교하여 약 1/2수준이었으며, 초산 농도는 2배정도 높은 것으로 확인되었다. 따라서 이 연구결과들은 사람으로부터 분리된 L. brevis HY7401이 높은 ADH와 ALDH 활성을 갖고 있어 에탄올과 acetaldehyde를 대사한다는 것을 의미하고 있다. 또한 L. brevis HY7401을 쥐에게 급여함으로써 혈중 에탄올 수준을 낮출 수 있는 것으로 확인되었다.
