The tracheary elements in secondary xylems of Actaea asiatica root and rhizomes were observered with a scanning electron microscope and found to contain abundant types, which mainly included tracheids, tracheid-like vessels, fibriform vessels, and typical vessels. Of these types, the tracheids, tracheid-like vessels, fibriform vessels were first found. Scalariform perforation plates, reticulate perforation plates, mixed perforation plates and simple perforation plates were observed in the typical vessels and the reticulate perforation plates ,mixed perforation plates were first founded the lateral-wall perforation plates, multiple end walls and pit membrane vestige were also observed in the tracheary elements.

Results of the experimental groups: Comparison with the control groups, in 6h and 8h groups eminences of ependymal cells with cobblestone-like appearance were seen, their microvilli were further richer, and a number of microholes could be found on their base. In body part of SFO cell membrane of some ependymal cells were broken completely, their cytoplasm was no longer seen, and cell nucleus located at one side of the cell, 5-7μm in diameter and dividing lobe-like in shape. Beside those cells some ependymal cells appeared many folds on the top of surface. In 2h and 16h groups the observation results seemed no significant differences from the corresponding control groups.
