六十年代以来,许多有关C细胞的研究,其机能意义得到进一步阐明。一般认为甲状腺内C细胞来自神经嵴,可分泌降钙素、加强成骨细胞的活性、抑制骨质溶解和骨钙释出、属于APUD系统。显示C细胞较理想的方法有组织块浸银法(即块染法)。其不足之处是:组织块经酒精和氨水固定后,组织和细胞收缩较大。以致整个组织结构变形,自然形象遭到破坏。其次容易产生过多的黑色银颗粒沉淀,影响切片标本的清晰度。我们曾对此进行改进,试用切片镀银方法,在镀银过程中按切片镀银的特点做相应的处理和改进,其效果较为满
Since the 1960s, many studies on C-cells have further elucidated their functional significance. Generally believed that intrathyroid C-cells from the neural crest, calcitonin secretion can enhance the activity of osteoblasts, inhibition of osteolysis and bone calcium release, belonging to the APUD system. The ideal method for displaying C cells is a tissue block dip method (ie, block method). The downside is: tissue blocks by alcohol and ammonia fixed, tissue and cells shrink larger. As a result, the entire organizational structure deforms and the natural image is destroyed. Second, prone to excessive deposition of black silver particles, affecting the clarity of the sectioned specimens. We have to improve this, the trial slice silver plating method, in the silver plating process according to the characteristics of slicing silver to do the appropriate treatment and improvement, the effect is more full
