软骨膜移植衍化软骨的动物实验和临床应用重建关节软骨已有报道,但对新生软骨的超微结构未见详细报道。本文系统观察了软骨膜的成纤维细胞衍化成软骨细胞的超微结构。材料与方法实验用健康家兔30只。体重2.2～4kg。雄性15只,雌性15只。在无菌技术及戊巴比妥钠静脉麻醉下(30mg/kg),分别把1×1cm大小的兔耳软骨膜移植于同一兔的三个部位:腹部皮下、腹壁肌层之间和去软骨的髌骨面上。分批于移植后1周、2周、4周、6周、 Although the articular cartilage reconstruction has been reported in animal experiments and clinical applications of cartilage graft-derived degenerated cartilage, no detailed reports have been reported on the ultrastructure of new cartilage. This article systematically observed the ultrastructure of chondrocytes derived from perichondria fibroblasts. Materials and Methods Experiments There were 30 healthy rabbits. Weight 2.2 to 4kg. There were 15 males and 15 females. Under aseptic technique and intravenous pentobarbital sodium (30 mg/kg), rabbit ear cartilage membranes of 1×1 cm in size were implanted in three sites of the same rabbit: between the abdomen subcutaneous and abdominal wall muscles and cartilage. The shinbone surface. Batched at 1 week, 2 weeks, 4 weeks, 6 weeks after transplantation
