鼓室成形术中使用软骨,在60年代早期已有报道,有些学者还曾描述过其组织学改变,但组织学方法并不能监测细胞代谢活性的微小改变及其活力;据Tushan等(1969)介绍,乳酸脱氢酶活性是测定软骨细胞和成软骨细胞代谢活性的最好方法之一,本文即就此分两部分进行研究。(1)用32只猫作实验研究,观察下列因素对移植的软骨柱不同部分活力的影响,即:软骨柱的一侧或双侧附有软骨膜;柱内、外端的接触区;鼓室内软骨柱穿有硅胶片。手术由耳后切口进入
Cartilage used in tympanoplasty has been reported in the early 1960s and some scholars have also described histological changes, but histological methods do not monitor small changes in cellular metabolic activity and their viability; as described by Tushan et al. (1969) , Lactate dehydrogenase activity is one of the best ways to determine the metabolic activity of chondrocytes and chondroblasts, this article is divided into two parts on this study. (1) 32 cats were used as experimental studies to observe the effects of the following factors on the vitality of different parts of the cartilage column transplanted: cartilage membrane on one or both sides of the cartilage column; the contact area of the inner and outer ends of the column; Cartilage worn with silicone film.
