The results show that the characters such as shape and pattern of anticlinal walls of epiderm , stomatal density , stomatal distribution and epidermal hairs possess the classific value of species 下表皮的结构远较上表皮摘要复杂，表皮细胞形态各异，有为数较多的气孔器，气孔密度、分布式样各不相同。

The evolutional trends of the twig , leaf , florescence , tepal and fruits were discussed . 2 . anatomy of both leaf and lemma epidermis micro - morphological characters of leaf epiderm is of 11 species and 1 varities of machilus distribute in zhejiang were examined by lm and sem 叶片表皮结构在光镜和电镜下观察润楠属植物叶表皮结构，结果表明：上表皮无气孔器，表皮细胞(表面观)的垂周壁式样由平直、浅波状和深波状变化。

P - selectin was negative both in the normal skin and in the postmortem damage group . in the wound specimens aged 1h , we detected expression of icam - 1 in the epidermis , a strong positive staining was observed in 3 hours after wound , and continued to 1 days from the skin was injured after incised , weak staining were showed on epiderm of the injury margin after 3 days incised , and disappeared in 5 days . expression of icam - 1 was also detectable in polymorphonuclear cells ( pmns ) in the wound specim - ents aged 3h 本实验研究证明，皮肤损伤后表皮层icam1表达增高，其表达呈现一定时间规律性，在损伤后lh ，损伤边缘表皮细胞即呈黄褐色染色，伤后3h组， icam一二在表皮层中呈深黄褐色，并一直持续至伤后id ，伤后3d组icam 1染色转淡，呈黄褐色染色，在伤后sd及7d组， 1 m一二表达基本恢复至正常状态。

It was probable that , in the lapse of ages , improved systems of moral and intellectual training would appreciably , perhaps considerably , elevate the involuntary and even the unconscious instincts of human nature ; but up to the present day culture , as far as he could see , might be said to have affected only the mental epiderm of those lives which had been brought under its influence 经过许多个世纪以后，道德和知识训练的体系大概也有了改进，就会在一定程度上，也许在相当大的程度上提高人类天性中不自觉的甚至是无意识的本能。但是就他看来，直到今天，也许可以说文化对于那些被置于它的影响之下的人，才在他们的表皮上产生了一点儿影响。
