Intraepithelial lymphocytes (IEL) were quantified in the uterovaginal junction (UVJ) and sperm-storage tubule (SST) epithelia in virgin hens 22 wk and inseminated hens 2 to 4, 10, and 22 wk after the onset of photostimulation. The UVJ epithelium of virgin and all inseminated hens possessed about 1 to 2 IEL/100 luminal epithelial cells. There were no significant interactions between hen fertility 22 wk postphotostimulation and the percentage of IEL in the UVJ or SST epithelia nor did the presence or absence of luminal sperm influence the percentage of IEL in the SST of inseminated hens. However, the percentage of IEL in the SST (with or without luminal sperm) was significantly higher 22 wk postphotostimulation than in the similar tissue at 2 to 4 and 10 wk. It is suggested that IEL at the SST may act to sequester sperm antigens or represent an autoimmune response to some factor(s) associated with the SST.
对22周龄的未受精母鸡以及光照刺激开始后2至4周、10周和22周的受精母鸡的子宫阴道交界处（UVJ）和储精小管（SST）上皮内的淋巴细胞（IEL）进行了定量分析。未受精母鸡和所有受精母鸡的UVJ上皮中，每100个腔面上皮细胞约有1至2个IEL。光照刺激后22周母鸡的受精率与UVJ或SST上皮中IEL的百分比之间没有显著的相互作用，并且腔面精子的存在与否也不影响受精母鸡SST中IEL的百分比。然而，光照刺激后22周时，SST中IEL的百分比（无论有无腔面精子）显著高于2至4周和10周时相似组织中的百分比。有人认为，SST处的IEL可能起到隔离精子抗原的作用，或者代表对与SST相关的某些因素的自身免疫反应。
