Thymus glands of two salmonid species, Salmo trutta and Oncorhynchus mykiss, caught monthly throughout the year, were examined by light and transmission electron microscopy. Erythropoietic foci, consisting of both developing and mature erythroid cells, occurred in the subcapsular, inner, and outer thymic zones from April to November. We discuss the possible physiological significance of this seasonal erythropoietic activity, together with the role played by the thymic cell microenvironments and endocrine factors.
全年每月捕获的两种鲑科鱼类，即褐鳟和虹鳟的胸腺，通过光学显微镜和透射电子显微镜进行了检查。由发育中和成熟的红细胞组成的造血灶，在4月至11月期间出现在被膜下、胸腺内部和外部区域。我们讨论了这种季节性造血活动可能的生理意义，以及胸腺细胞微环境和内分泌因素所起的作用。
