Significant changes in the size of thymic cortex and of thymus-dependent areas (TDA) in spleen and lymph nodes, were revealed by histomorphometry after intraperitoneal injection of BCG into young-adult BALB/c mice. Reactions of the thymic cortex were found to be biphasic with initial involution and subsequent hyperplasia. TDA in the spleen showed a transient involution with almost complete regeneration at the end of the experiment. The response of TDA in lymph nodes was characterized by pronounced and persistent hyperplasia. The functional significance of these BCG-induced changes of lymphoid tissue compartments is discussed.
对年轻成年BALB/c小鼠腹腔注射卡介苗后,通过组织形态计量学发现,胸腺皮质以及脾脏和淋巴结中胸腺依赖区(TDA)的大小发生了显著变化。胸腺皮质的反应呈双相性,最初是退化,随后是增生。脾脏中的TDA出现短暂退化,在实验结束时几乎完全再生。淋巴结中TDA的反应特征是明显且持续的增生。本文讨论了这些卡介苗诱导的淋巴组织区室变化的功能意义。
