The results showed that compared with soil culture, the root cap was not obvious with less amyloplast and polysaccharose substance under water culture. The root epidermis under water culture was thinner than that of soil culture, with little root hair or not, in which cortex parenchyma tissue developed with big cell, solution proliferative aerenchyma in intercellular space, and thin cell wall. However, the root cap under soil culture was big, with strong PAS reaction and no aerenchyma tissue.

结果表明：水培后根冠不明显，淀粉体较少，多糖类物质较少而土培根根冠体积较大，淀粉体较多，多糖类物质多，土培根PAS反应强烈；水培根表皮厚度比土培根小，水培根根毛少或退化消失；水培根皮层薄壁组织发达，细胞大型，壁薄，细胞间隙中含有溶生性通气组织，土培根皮层未见通气组织。

by summarizing and analysing the progress on studies of pharmacodynamic material basis of resuscitation-inducing aromatic herbs such as moschus,borneolum syntheticum,styrax,benzoinum, and exploring the generality of those herbs,to provide scientific reference for further studies on the relevance of common substance ,nature and the efficiency of restoring consciousness and inducing resuscitation of those herbs.the result indicates that those four resuscitation-inducing aromatic herbs mainly contain volatile oil ,and all contain alicyclic compounds; the volatile oil of borneolum syntheticum and styrax both contain sesquiterpenes of caryophyllene; as resin herbs , styrax and benzoinum both contain vanillin, resin ester and balsamic acid .

通过对芳香开窍药麝香、冰片、苏合香、安息香的药效物质基础研究进展的整理、分析，探索其共性，拟为深入研究该类药的共性物质—药性—开窍醒神效应之间的关联性提供科学参考。结果表明，四味芳香开窍药主含挥发油，均含有脂环化合物，并存在一些共有成分，如龙脑冰片与苏合香挥发油中均含有倍半萜类成分石竹烯；苏合香和安息香皆为树脂类中药，两者均含有香荚兰醛成分，尚含树脂酯，香脂酸等。

With the discovery of the radio-elements, physicists found themselves for the first time confronted with strange substances, minute generators of radiation endowed with an enormous concentration of energy; alpha rays, positively charged helium atoms, beta rays, negatively charged electrons, both possessed of a kinetic energy which it would be impossible to communicate to them by ''.

由于放射性元素的发现，物理学家们第一次发现自己面临许多陌生的物质——许多具有巨大的浓缩能量的、能够发生辐射的细微物质，如射线，即带正电荷的氦原子小射线，即带负电荷的电子。

Results:①Excitation of the NVM by L-glut amate,injection of substance P into the nucleus dorsomedialis, n ucleus paraventricularis or rostral ventrolateral medulla,all induce d pressor responses.②NVM pressor responses could be attenuated by preinjection of ［D-Pro2,D-Phe7,D-Trp9］-SP (DPDPDT,a substance P antagonist)bilate rally into the NDM,NPV or RVL,but preinjection of atropine into the RVL had no s uch effect.

结果 ：①L-谷氨酸兴奋NVM、P物质注入背内侧核室旁核或延髓头端腹外侧区均引起升压反应；②NVM升压反应可被双侧NDM、NPV或RVL内预先注射［D- Pro2，D-Phe7，D-Trp9］-P物质衰减，但RVL内注射阿托品无此效应；③酚妥拉明i.v。
