CT can differentiate freebodys in the joint cavity with the calcification of the soft tissue or joint sac .

在EBV溶解性感染的细胞里EBVDNA呈线状形式，而在潜伏性感染时，EBVDNA通过基因组末端连接而环化，以游离体形式存在。

EBV DNA is detected as a linear form in cells at the lytic phase of EBV infection , but during latent infection the viral genome is maintained in episomal form through the fusion of genomic termini .

相同标本中Ⅰ型胶原蛋白仅在游离体内部软骨细胞中有表达，表达的阳性信号相对较低，未见明显的Ⅱ型胶原表达。

As to collagen type ⅰ expression , it was weakly positively stained in the chondrocytes of loose bodies .

然而，如果游离体被卡或附着在滑膜上，一般都会被吸收。

However , if the loose body becomes trapped and reattaches to the synovium , it is then generally reabsorbed .

增强扫描滑膜明显增厚强化，腱鞘内游离体未见明确强化。

CT showed the synovial membrane were obvious thickening and enhanced , corpus liberum in tendon sheath were no obvious strengthening .

目的观察关节游离体软骨细胞的生物学特性，寻找组织工程软骨种子细胞来源。

The debridement included the removal of the loose body , hyperplasia of synovial membrane , degenerated cartilage , and the torn meniscus .

光和术中都没有发现骨块有血液供应，游离体的表面是很光滑的。

No donor site for the fragment was apparent either radiographically or intraoperatively , and the surfaces of the loose body were quite smooth .

结论游离体软骨细胞已具有成纤维细胞特性，不宜直接作为组织工程的种子细胞来源。

Conclusion The characters of chondrocytes from loose body is more like fibroblasts so they can not serve as seeding cells directly for cartilage tissue engineering .
