It was observed that the influence of bud and its position on the healing process of grafting unions using hardwood sectioning method, and found that:(1) bud of a scion and its position to the graft unions have no influence on callusing formation of the isolation layers, and the early differentiation of cambia;(2) a scion bud closer to the grafting union would promote the formation of more compacted callus cells and the earlier formation of callus bridges;(3) conduit differentiation in grafting unions of lower-bud scions was later than that of other treatments.

利用滑动切片法对芽子有无及芽位对嫁接愈合过程的影响进行了观察，发现：(1)接芽有无及芽位对隔离层及愈伤组织形成和形成层的早期分化没有影响；(2)芽或去芽的芽位距接口近，可以促进愈伤组织的紧密连接，即愈伤组织桥的形成；(3)低位芽枝嫁接体中导管分化较晚，而其它处理导管的分化几乎是同时发生的，而且导管首先出现于愈伤组织薄壁细胞中。

The new recommendation presented for the use of second generation Microcuff with improved OD to ID ratio allows the selection of cuffed tracheal tubes with larger IDs than previously recommended for small children without increased need for tracheal tube exchange or increased incidence of post intubation stridor in these age groups .

这一新的推荐套囊导管，即使用改善外径和内径比的第二代微囊PETs，比以前推荐的管子用于较小的儿童时，可以选择更大内径的套囊气管导管而不会增加相同年龄组气管导管的更换率或增加插管后喘鸣的发生率。
