瘢痕的

At the 8 week postoperatively,three groups still have not restored the normal thichness of corneal epithelial cell;but in the blank group there was more neoformative irregular collagen in the anterior stromal layer.

术后4周，三组覆盖切削区的角膜上皮细胞仍有轻度增生，空白组前基质层内较多新生胶原，排列不规则，失去板层结构，瘢痕形成。

However, chronic injuries usually require complete reconstruction of the superficial medial collateral and posterior oblique ligaments because of extensive pericapsular scar formation.

然而，陈旧性损伤由于关节囊周围广泛的瘢痕增生，往往须要对内侧副韧带前侧和后斜韧带进行完全重建。

OBJECTIVE: To establish animal models of fetal scarless healing.

目的：建立人胎儿无瘢痕愈合的动物模型。

Growth environment of fetus has not so much relationship with the mechanism of scarless healing after trauma.

胎儿的生长环境与伤后无瘢痕愈合机制关系不大。

DATA EXTRACTION: Forty-eight articles on experimental study relating to embryonic scarless healing were collected in all. Sixteen experiments accorded with the inclusive criterion and 32 were excluded.

资料提炼：共收集到48篇与胚胎无瘢痕愈合相关的实验研究，16个实验符合纳入标准，排除32篇。

High density and high activity of cells are important factors for the formation of hypoxic environment in scarring.

组织内高细胞密度、高细胞活性是形成瘢痕内缺氧环境的主要原因。

Scarring is characteristic of certain inflammatory processes and is therefore of diagnostic value.

瘢痕是某些炎症性疾病的特征，故有诊断价值。

In part that's because we had no way to treat the underlying liver disease that led to that scarring.

部分原因是因为我们没有方法治疗那些导致瘢痕产生的潜在性疾病。
