在以往的嗜银染色中由于染色时间长、操作较为复杂，制约了这种技术的广泛应用。我们经复习文献发现２种改进法既可保证染色结果又能缩短染色时间。为了更好地了解和掌握这２种方法，我们作了应用染色实验，并根据条件对原方法稍作修改，现报道如下。１　材料和方法１１　材 In the past argyrophilic staining due to the long dyeing time, the operation is more complicated, restricting the widespread use of this technology. After reviewing the literature, we found that the two improved methods can not only ensure the dyeing result but also shorten the dyeing time. In order to better understand and master these two methods, we made the application of staining experiments, and according to the conditions of the original method slightly modified, are reported below. 1 Materials and methods 1.1 material
