5 cases underwent grainage by percutaneous liver puncture under guiding of X-fluoroscopy to treat liver abscess, in which there were 3 males and 2 females, age from 21 to 72 diagnosed by CT and ultrasound.

2003年以来我们收治肝脓肿5例，在X线透视引导下经皮肝穿刺置管引流治疗，本组5例。男3例，女2例；年龄21～72岁；均进行了CT、B超检查确诊。

Macromorphology of seeds and micromorphology of the seed-coat in 53 species and 5 varieties belonging to three genera (Smilax, Heterosmilax and Ripogonum) of Smilacaceae were observed under the light microscope and the scanning electron microscope. The seeds are spheroidal, hemispheroidal or trigonal-oblate in shape.

METHODS: Full-thickness skin was sterilely obtained from rabbit ears. 2 cm×2 cm free skin graft was placed in 0.25% pancreatin-EDTA to remove epidermis, in Qulatong X-100 solution to completely take off hypodermal cells, repeatedly rinsed in phosphate buffer saline. Thus, acellular dermal matrix was collected, and kept at 4 ℃ for usage.

无菌条件下切取兔耳全层皮肤，将2 cm×2 cm皮片置于0.25%胰酶-EDTA消化液中去掉表皮，再置入曲拉通X-100溶液使真皮细胞完全脱净，磷酸盐缓冲液反复清洗，即为脱细胞真皮基质，4 ℃保存备用。
