5 年来羊栖菜生药鉴定、化学成分及其药理作用的研究进展. 【出处】时珍国医国药,2005 年6期【原文】该数据库提供了全文. [9] 【篇名】羊栖菜多糖抑脂沉积及其机制研究 【作者】姬云涛,王娟,张会等. 【文摘】 目的 研究羊栖菜多糖(SFPS)对秀丽隐杆线虫脂肪沉积的影响,并探 讨其机制.方法 用不同浓度SFPS配制NGM 培养同步化秀丽隐杆线虫,经油红O染 色后,裂解虫体,在490nm波长处测定吸光度值,同时采用外翻肠囊法,考察不同浓度 SFPS被大鼠小肠吸收的情况.结果 在含不同浓度SFPS配制的NGM 培养基上生 长的线虫,当SFPS浓度越高,线虫吸光度值越小,与对照组相比差异显著.在低剂量浓 度下( 0.05) different in both algae following gamma radiation. The Weibull model was used to generate non-linear survival curves and to calculate Gd values for 1, 2, and

3 log10 reductions of MNV-1 in fulvescens (R2 = 0.992) and fusiforme (R2 = 0.988). A Gd value of

1 (90% reduction) corresponded to 2.89 and 3.93 kGy in fulvescens and fusiforme, respectively. A Gd value of

2 (99% reduction) corresponded to 7.75 and 9.02 kGy in fulvescens and fusiforme, respectively, while a Gd value of

3 (99.9% reduction) in fulvescens and fusiforme corresponded with 13.83 and 14.93 kGy of gamma radiation, respectively. A combination of gamma radiation at medium doses and other treatments could be used to inactivate ≥

3 log10 PFU/ml NoV in seaweed. The inactivation kinetics due to gamma radiation against NoV in these algae might provide basic information for use in seaweed processing and distribution. 【出处】Food Microbiology,Volume 56, June 01, 2016, Pages 80-86 【原文】该数据库提供了全文. [17] 【篇名】Antimicrobial activity of some seaweeds species from Red sea, against multidrug resistant bacteria 【作者】El Shafay, S.M., Ali, S.S., El-Sheekh, M.M. 【文摘】This study evaluates the antibacterial activity of diethyl ether, methanol, ethanol and chloroform extracts of red algae Ceramium rubrum (Rhodophyta), Sargassum vulgare, Sargassum fusiforme and Padina pavonia (Phaeophyta) collected from Red sea, Egypt. The algal extracts were tested for their antibacterial activity against ten multidrug resistant clinical isolates of Gram

13 positive and Gram negative bacteria. The highest inhibition activity among all extracts was obtained with

100 μl diethyl ether extract S. fusiforme against Staphylococcus aureus

2 and

50 μl ethanol extract of S. vulgare against Klebsiella pneumoniae. The algal extra........
