이신호,최우정,임용숙,김순희 대구효성가톨릭대학교 식품과학연구소 1997 식품과학지 Vol.9 No.-
천연물에서의 항균성 물질의 검색과 김치제조에 응용할 목적으로 울금 ethanol 추출물의 김치 발효관련 유산균과 병원성 미생물이 대한 항균력과 울금추출물을 김치제조시 1% 첨가하여 10℃에서 숙성시키면서 숙성중 변화를 관찰한 결과 울금 ethanol 추출물은 유산균 4 균주와 병원성 균주에 대해 높은 항균효과를 나타내었고 유산균은 배양 12시간 후 울금 첨가구에서 생균수가 감소하였고 병원성 미생물은 성장은 2~3 log_(10) cycle의 억제효과를 나타내었다. 김치 숙성 중 pH, 산도는 숙성 10일 이후부터 숙성 지연효과가 있는 것으로 관찰되었으나 미생물의 변화는 대조구와 첨가구가 숙성 5일 이후로 차이를 보였으나 뚜렷한 억제경향은 보이지 않았다. 울금 추출물을 첨가한 김치에 대한 관능검사는 숙성 전기간에 걸쳐 대조구에 비해 첨가구의 기호도가 떨어지는 것으로 관찰되었다. Antimicrobial effect of ethanol extract from Curcuma aromatica S.(CA) and its effect on kimchi fermentation were investigated. Antimicrobial activities of the extract against 4 kinds of lactic acid bacteria isolated from kimchi and 6 kinds of pathogenic bacteria showed apparently. The growth of the tested bacteria did not occur in modified MRS broth containing 1% of CA except three strains of Listeria monocytogenes. The pH of kimchi containing 1% of Curcuma aromatica S. extracts was higher than that of control but titratable acidity, total bacteria count and Lactobacilli count were lower than control during fermentation for 25 days at 10℃. The sour taste of CA added kimchi was weaker than that of control. Sensory score of flavor did not show significant difference between CA containing kimchi ant control but overall acceptability of CA added kimchi was lower than control during fermentation.

이은희,남은숙,박신인 한국식품영양학회 2002 韓國食品營養學會誌 Vol.15 No.1
Skim milk에 매실 착즙액을 수준별로 첨가하고 4종 (Streptococcus thermophilus, Lactobacillus acidophilus, Lactobacillus bulgaricus, Lactobacillus casei)의 젖산균을 단독균주 또는 혼합균주로 접종하여 매실 착즙액의 첨가가 젖산균의 산생성 및 생육에 미치는 영향과 저장성을 조사하였고, 매실 착즙액으로 사용한 매실의 일반 성분을 분석하였다. 매실의 일반 성분은 조회분 0.4%, 식이섬유 4.1%, 구연산 4.66%, 총당 0.264%, vitamin C 405.34mg%이었고, 매실 착즙액의 첨가는 젖산균의 증식을 촉진시켰으며 산생성도 증가하였다. 실험구 중 Str. thermophilus, Lac. acidophilus와 Lac. casei의 혼합균주에 3% 매실 착즙액을 첨가한 실험구가 가장 많은 양의 젖산 (1.23%)을 생성하였고, 가장 높은 생균수 (3.6×10^11 cfu/mL)를 나타내었다. 매실 착즙액 3% 첨가 호상 요구르트를 대조구와 함께 4℃와 20℃에서 30일 동안 저장한 결과, 세 개의 혼합균주 (Str. thermophilus, Lac. acidophilus, Lac. casei)를 사용한 호상 요구르트가 4℃에서 pH는 4.25, 생균수는 4.1×10^9 cfu/mL이었고, 20℃에서 pH는 3.76, 생균수는 8.7×10^8 cfu/mL으로 대조구인 매실 무첨가 호상 요구르트에 비하여 높은 저장성을 나타내었다. 이상의 결과로 보아 매실 착즙액을 첨가한 호상 요구르트의 제조가 가능할 것으로 사료된다. This experiment was carried out to investigate the effect of Maesil extract on the acid production and growth of yoghurt starter in the skim milk medium. The Maesil extract was added to skim milk medium for 1% to 9% and the medium was fermented by single or mixed culture of 4 types of lactic acid bacteria (Streptococcus thermophilus, Lactobacillus acidophilus, Lactobacillus bulgaricus, Lactobacillus casei). The chemical composition of Maesil, the changes in acid production (titratable acidity, pH) and number of viable cells of the medium during lactic fermentation in skim milk added with Maesil extract, and the keeping quality of curd yoghurts containing Maesil extract have determined. The composition of Maesil were 0.4% crude ash, 4.1% dietary fiber, 4.66^ citric acid, 0.264% total sugars and 405.34mg% vitamin C. The addition of Maesil extract stimulated the acid production and propagation of the lactic acid bacteria. Among the treatments tested, the addition of 3% Maesil extract with the mixed culture of Streptococcus thermophilus, Lactobacillus acidophilus and Lactobacillus casei produced the highest amount of acid (1.23%) and showed the highest number of viable cell counts (3.6×10^11 cfu/mL). When the curd yoghurts containing 3% Maesil extract with the mixed culture of the lactic acid bacteria were kept at 4℃ and 20℃ for 30 days, it was showed that the changes of titratable acidity, pH and number of viable cell counts of the lactic acid bacteria were not significantly different during storage. Therefore the keeping quality of the curd yoghurts adding 3% Maesil extract showed relatively good at the shelf-life.

이신웅,박영주,박인숙,이정수 영남대학교 약품개발연구소 1991 영남대학교 약품개발연구소 연구업적집 Vol.1 No.-
A single uniform population of specific, saturable, high affinity binding site of [³H] guinuclidinyl benzilate(QNB) was identified in the rat cerebral microsomes. The Kd value(37.2 pM) for [³H]QNB calculated from the kinetically derived rate constants was in agreement with the Kd value(48.9 pM) determined by analysis of saturation isotherms at various receptor concentrations. Dimenhydrinate(DMH), histamine H₁-blocker, increased Kd value for [³H] QNB without affecting the binding site concentrations and this effect resulted from the ability of DMH to slow [³H]QNB-receptor association. Pirenzepine inhibition curve of [³H]QNB binding was shallow(nH = 0.52) indicating the presence of two receptor subtypes with high (M₁-site) and low(M₂-site) affinity for pirenzepine. Analysis of these inhibition curves yielded that 68% of the total receptor populations were of the M₁-subtype and the remaining 32% of the M₂-subtype. Ki values for the M₁- and M₂-subtypes were 2.42 nM and 629.3 nM, respectively. Ki values for H₁-blockers that inhibited [³H]QNB binding varied with a wide range (0.02-2.5μM). The Pseudo-Hill coefficients for inhibition of [³H]QNB binding by most of H₁-blockers examined except for oxomemazine inhibition of [³H]QNB binding were close to one. The inhibition curve for oxomemazine in competition with [³H]QNB was shallow(nH = 0.74) indicating the presence of two receptor populations with different affinities for this drug. The proportion of high and low affinity was 33:67. The Ki values for oxomemazine were 0.045±0.016 μM for high affinity and 1.145±0.232 μM for low affinity sites. These data indicate that muscarinic receptor blocking potency of H₁-blockers varies widely between different drugs and that most of H₁-blockers examined are nonselective antagonist for the muscarinic receptor subtypes, whereas oxomemazine might be capable of distinguishing between subclasses of muscarinic receptor.
닭에서 Ethanol의 中樞作用이 血漿內 葡萄糖 濃度에 미치는 影響
李神雄,姜仁淑 충남대학교 의과대학 지역사회의학연구소 1975 충남의대잡지 Vol.2 No.1
The present experiments were undertaken in an attempt to elucidate the central effect of ethanol on the plasma glucose level in the hen. After intravenous administration of 30mg/kg ethanol to control group, plasma glucose concentration was not affected but over 100mg/kg, it induced hypoglycemia. Hypoglycemic effect of intravenous ethanol was potentiated by adrenergic blocking agents. Intraventricular administration of 30mg/kg ethanol resulted in a significant increase in the plasma glucose level, and this hyperglycemic effect of intraventricular ethanol was inhibited by regitine, propranolol, or reserpine. It suggests that metabolic effect of ethanol on the plasma glucose concentration in the hen is mediated partially by the activation of sympathetic center.

도체표면에서 분리한 E. coli O157:H7 CDF1, A. sobria CDF3, S. aureus CDF2의 성장을 억제하기 위한 방안을 검토하였다. E. coli O157:H7 CDF1, A. sobria CDF3는 NaC1 4%이상 농도에서 성장이 억제된 반면 lactic acid 0.1%는 성장에 영향을 미치지 않았다. S. aureus CDF2은 NaCl 농도 4%에 의해 성장이 뚜렷하게 억제되지 않았으나 lactic acid 0.1% 첨가에 의해 뚜렷히 억제되었다. E. coli O157:H7 CDF1은 분쇄육에서 4℃와 10℃에서 저장하는 동안 저장온도별 약 1log 차이를 나타내었고, A. sobria CDF3의 성장은 저장온도에 따른 차이는 나타나지 않았다. 60℃에서 10분 열처리 후 E. coli O157:H7 CDF1, A. sobria CDF3가 거의 사멸하였으나 S. aureus CDF2는 대조구에 비해 1log cycle 이하의 감소현상을 나타내었다. 감잎, 뽕잎, 녹차, 우롱차의 추출물중 E. coli O157:H7 CDF1, A. sobria CDF3, S. aureus CDF2에 대한 항균활성을 나타낸 우롱차 추출물 0.1%와 0.3% 첨가에 의해 E. coli O157:H7 CDF1는 성장 억제되지 않았으나 0.5%첨가구의 경우 약 2 log 감소하였다. A. sobria CDF3와 S. aureus CDF2는 추출물 0.1%와 0.3%첨가에 의해 성장이 억제되었으며 0.5%첨가에 의해 배양 12시간이후 생균수는 검출되지 않았다. 우롱차 추출물을 분쇄육에 0.3%와 0.5%를 첨가하여 20℃에서 24시간 저장한 결과는 E. coli O157:H7 CDF1, A. sobria CDF3, S. aureus CDF2은 우롱차 추출물을 0.5첨가한 경우 성장이 억제되는 경향을 나타내었다. Effects of acid, salt, heat treatment and natural antimicrobials on survival of E. coil O157:H7 CDF1, A. sobria CDF3 and S.aureus CDF2 isolated from surface of carecass in minced meat was investigated. The growth of E. coli O157:H7 CDF1 and A. sobria CDF3 inhibited in minced meat congtaining above 4% NaCL but not in 1% lactic acid. The growth of S. aureus CDF2 yas not inhibited significantly by addition of 4% NaCl but inhibited completely in minced meat containing 1% lactic acid. Survial of A. sorbia CDF3 did not show any differences during storage at 4 and 10℃. E. coli O157:H7 CDF1 and A.sobria CDF3 did not detect after heat treatment at 60℃ for 10 min but S. aureus CDF2 decreased only 1 log after the same treatment. Viable cell of E. coli O157:H7 CDF1 decreased 2 log in TSB containing 0.5% Oolong tea extract after incubation for 12 hr compared with control but A. sobria CDF3 and S.aureus CDF2 did not detect at the same condition. The growth of E. coli O157:H7 CDF1, A. sobria CDF3 and S.aureus CDF2 was not inhibited by addition of 0.3% Oolong tea extract but inhibited by addition of 0.5% Oolong tea extract in minced meat at 20℃ for 24hr.
