降钙素基因相关肽免疫反应神经纤维在大鼠脾的分布

用免疫组织化学ＡＢＣ法，研究了降钙素基因相关肽免疫反应神经纤维在大鼠脾内的分布，在大鼠脾内有丰富的ＣＧＲＰ免疫反应神经纤维，它们多呈串珠状，主要分布于红髓。尤其是脾血窦和一些小血管，也见于边缘区的淋巴组织中，偶见于动脉周围淋巴鞘，脾内ＣＧＲＰ免疫反应神经纤维与淋巴细胞关系密切，可能参与调节脾淋巴细胞的发育和功能。

DISTRIBUTION OF CALCITONIN GENE-RELATED PEPTIDE IMMUNOREACTIVE NERVE FIBERS IN THE SPLEEN OF RAT

In this study, the distribution of calcitonin gene-related peptide immunoreactive (CGRP-IR) nerve fibers in the spleen of the rat was investigated by using the immunohistochemical ABC method combined with glucose oxidase-DAB-nickel enhancement technique. The results showed that the rat spleen was richly innervated by CGRP-IR fibers. The nerve fibers containing CGRP were mainly distributed in the red pulp, especially surrounding the splenic sinusoid and small blood vessels. They were also observed in the lymphoid tissue of marginal zone, and occasionally in the periarterial lymphatic sheath (PALS). The positive fibers distributed in the spleen, which suggested that the fibers might modulate the development and function of splenic lymphocytes.
