大鼠胸腺神经分布的初步研究

ELEMENTARY STUDY ON INNERVATION OF RAT THYMUS

采用改良的银染色法观察了大鼠胸腺神经纤维的分布。结果表明：胸腺皮质和髓质神经纤维的分布存在着明显的差异，即髓质神经纤维可形成复杂的网络状结构。认为这可能是与胸腺细胞发育的局部微环境不同有关，其微环境的变化可能受神经的支配。此处，神经纤维的分支末梢终止于胸腺细胞附近，有的分支与肥大细胞紧密相依，还有的分支伴随小血管走行，形成血管周围神经丛。由此认为，神经纤维对胸腺细胞、肥大细胞和血管均起调节作用。

The innervation of rat thymus was observed by silver stain method.It was shown that the innervation of the medulla, different from that of the cortex,was characterized by the formation of a complex network of nerve fibers.This formation was thought to be related and regulatory to theφ microenvironment for the development of thymocytes.It was also found that the nerve endings terminated by the thymocytes, some contacted mast cells and some formed plexus around small blood vessels.Thus it can be inferred that the thymocytes,mast cells and blood vessels may all be regulated through nerve fibers.
