In 1883,henry ***,the first President of the American Physical Society and Professor of Physics at Johns Hopkins University,published an essay entitled“A Plea for Pure Science”in Popular Science *** took the development of gunpowder as an example to emphasize that SCIEnCE itself must be sought in the applications of science.“They(Chinese)have known the application of gunpowder for centuries;and yet the reasons for its peculiar action,if sought in the proper manner,would have developed the science of chemistry,and even of physics,with all their numerous applications.”

Objective: To evaluate the antimicrobial and antifungal activities of the aqueous and partitioned extract of sea anemone Anthopleura nigrescens(A. nigrescens).Methods: The sea anemone A. nigrescens was collected, minced, homogenized,lyophilized and then further partitioned with diethyl ether, acetone, ethanol and *** fractions were evaluated for antimicrobial activity against bacterial and fungal ***: Acetone extract was found to produce a pronounced inhibition of 7.0 mm against Proteus vulgaris and diethyl ether extract inhibited Pseudomonas aeruginosa with an inhibition zone of 6.5 mm. In antifungal activity, ethanol extract showed good activity against Botrytis cinerea, Trichoderma harzianum and Rhizopus oryzae compared with other strains. Acetone and ethanol extract of A. nigrescens showed activity against all of pathogens tested. Slight activity was observed in the water extract with inhibition zone of 1.5 ***: The present study revealed that sea anemone A. nigrescens may also contain some biologically active agents which have potential activity against pathogenic microorganisms.

如果让我用一张照片来体现一家葡萄酒庄的风格,我想会选一张庄主或是酿酒师(有的是主人兼酿酒师)在酒窖里品酒的画面。原因就在于主人和酿酒师是掌握葡萄酒品格和灵魂的关键。而酒窖则是蕴藏无数灵魂的"天堂",怪不得有的庄主给自己的酒窖起了一个动听的名字叫"Paradis",酒窖明明在地下却有天上人间的美名,想来定是美酒起的作用。
