Ligature of the cervical lymph duct in guinea pigs resulted in marked dilatation of the lymphatics draining the thymus and marked reduction of mitosis in the thymus. A decrease of about 50% in the number of mitoses was found in the cortex within one day after ligation and in the medulla within five days after ligation. The thickness of the cortex also decreased rapidly and markedly in direct proportion to the decrease in cortical mitosis. Mitosis in the thymus recovered within 10 days after ligation, presumably after regeneration of lymphatics or collateralization. Thickening of the walls and valves of the efferent lymphatics of the thymus after lymph congestion was also demonstrated.
结扎豚鼠的颈淋巴导管会导致引流胸腺的淋巴管明显扩张，且胸腺中的有丝分裂显著减少。结扎后一天内，皮质中的有丝分裂数量减少约50%，结扎后五天内，髓质中的有丝分裂数量减少约50%。皮质厚度也迅速且显著下降，与皮质有丝分裂的减少成正比。结扎后10天内，胸腺中的有丝分裂恢复，推测是在淋巴管再生或侧支循环形成之后。淋巴充血后，胸腺输出淋巴管的壁和瓣膜也出现增厚。
