Of 522 cells with Nissl stain,47.89%(250/522) were small,while 52.11%(272/522) were large in size. Accordingly,it was shown that almost all of the MOR Li and BSI B 4 binding cells in monkey DRGs fell into a sub group of small cells.

• 522 个尼氏染色细胞中，47?89%25 （250/522）为小细胞，而52?11%25 （272/522）为大细胞，由此可见，猴DRG中的MOR?Li和BSI?B4 阳性细胞几乎都属于小细胞群。
