This study investigated the anti-amnesic effect of fermented Ganoderma lucidum water extracts (GW) on scopolamine-induced memory impairment in rats. GW were by lactic acid bacterium Bifidobacterium bifidum (FGWB), followed Lactobacillus sakei LI033 (FGWBL). To induce amnesia, scopolamine (1 mg/kg) was intraperitoneally injected into rats 30 min before behavioral tests. Step-through latencies treated with primary (300 mg/kg, FGWB) and secondary FGWBL) significantly longer than those retention...
This study was conducted to examine the quality and storage characteristics of yogurt containing antifungal-active lactic acid bacteria (ALH, Lacobacillus sakei ALI033) isolated from kimchi cinnamon ethanol extract. The starter used for culture inoculation (1.0 % commercial YF-L812 ALH).The antifungal activity extracts observed in treatments with either or methanol extracts. Changes fermented milk made ALH extract during fermentation at 40 °C were as follows. pH 4.6 after only 6 h...
본 연구에서는 유산균을 이용하여 3종의 버섯(상황, 영지, 표고)을 단계적으로 발효하여 항산화 활성을 비교하였다. 활성이 밝혀진 표준 유산균 5종을 선발하여 버섯 열수 추출물의 1차 발효에, 임실 지역 김치로부터 분리한 1종을 최종 2차 발효에 이용하였다. 추출물과 1차, 발효물의 활성 평가를 위해 DPPH 및 ABTS 라디칼 소거 정도를 추출물 발효물은 농도 의존적으로 라디칼을 소거하였지만 발효를 통하여 상황과 영지의 경우 감소하였다. 이는 발효 과정 중 폴리페놀 화합물과 비타민 C, E 등 천연 물질들의 산화에 기인한 결과라고 사료되었다. 그러나 생산되는 대사산물 유효성분은 XO 효소의 저해시키고 SOD 증가시켰으며, 발효보다 발효에서 증가되었다. 특히 5 mg/mL 이상의 농도에서 영지 90% 이상 저해하였으며, 상황 3배 효소 증가시켰다. 유산균에 의한 발효물이 저해 혹은 활성화시켜 항산화에 기여하는 것으로 판단되었다.
Salvia plebeia has been used to treat a variety of inflammatory diseases, as well colds and bronchitis. Macrophages have antioxidant defense mechanisms cope with the intracellular reactive oxygen species (ROS) produced part immune response. The nuclear factor erythroid 2-related 2 (Nrf2)/heme oxygenase (HO)-1 pathway in inflamed macrophages is an appealing target due its protective effect against ROS-induced cell damage. In this study, nepetoidin B (NeB) was first isolated from S. identified...
본 연구는 치즈 숙성 중 오염원인 곰팡이균 제거기술 개발의 일환으로 수행하였다. 및 숙성실에서 자생하는 곰팡이를 분리하고, 지역별 김치로부터 유산균을 분리하여 곰팡이에 대한 항진균 활성을 측정한 결과는 다음과 같다. 치즈와 숙성실에 분리된 곰팡이는 총 8종으로Penicillium과 Cladosporium으로 동정되었다. 유산균은 44종이고 이 보인 유산균 22종을 동정한 결과 Lactobacillus와 Pediococcus로 확인되었다. 동정된 김치 분리 22종 활성도가 높은 6종(L. sakei subsp. ALJ011, L. ALI033, ALGy039, P. pentosaceus ALJ015, ALJ024, ALJ026)을 선발하여, 8종에 대하여 전주지역 김치에서 분리한 유산균인 ALJ024과 임실지역 ALI033 균주가 활성이 높게 나타났다. 배양액의 최소저해 농도를 측정해 결과, 생육저지환으로 알아본 항균활성 실험과 동일하게 대하여L. 유산균의 가장 크게 The...
Yak-Kong is a type of black soybean that colloquially referred to as the “medicinal bean” and it elicits several beneficial effects are relevant human health, including attenuating formation skin wrinkles. It has previously been shown extracts elicit additional bioactivity fermented by lactic acid bacteria. In this study bacteria strains were isolated from stools breast-feeding infants (<100 days old), we selected Bifidobacterium animalis subsp. Lactis LDTM 8102 (LDTM 8102) lead strain...
This study compares the chemical composition, antioxidant effect, and anti-inflammatory potential of different parts (whole, flesh, peels) Codonopsis lanceolata roots (CLR).Component analysis performed using liquid chromatography (LC) revealed that contents vitamin B2, B3, tangshenoside I, lobetyolin, lancemaside A, total polyphenol were highest in CLR peels.Moreover, peels also showed activity.All components inhibited oxidative stress enhanced mitochondrial biogenesis LPS-treated RAW 264.7...
<b>Background</b> Decortication for chronic pleural empyema (CPE) is to restore lung volume by removing sac and thickened pleura. Extent of restoration after decortication has been undefined. This study aims evaluate using densitometry with three-dimensional reconstruction computed tomography (CT). <b>Methods</b> We studied 23 patients CPE who underwent follow-up CT. CT pulmonary function test (PFT) were evaluated at a median 19.1 months postoperatively. The volumes operated nonoperated...
<b>Background</b> The aim of this study was to evaluate the role maximum standardized uptake value (mSUV) main mass as a risk factor for recurrence in patients with completely resected esophageal squamous cell carcinoma (ESCC). <b>Patients and Methods</b> Clinicopathologic factors including primary tumor location, size, depth invasion, number positive lymph nodes, angiolymphatic mSUV were analyzed recurrence. prognostic influence variables on disease-free survival using log-rank test...
