Morphologic and physiologic changes which occur during senescence in the free-living nematode Turbatrix aceti are described. With age areas of the interchordal hypodermis containing nerve elements thickened, electron-dense aggregates formed within the pseudocoelom and age pigment granules accumulated within the intestinal epithelium. Specific gravity did not change with age. Old nematodes which had reproduced showed increased osmotic fragility, but this change was not observed in virgin females. The parameters characterizing senescence in T. aceti are compared with those of Caenorhabditis briggsae, another nematode being used as a model to study biological ageing.
本文描述了自由生活的醋酸布氏线虫衰老过程中发生的形态学和生理学变化。随着年龄增长，含有神经成分的弦间皮下区域增厚，假体腔内形成电子致密聚集体，肠上皮内积累了老年色素颗粒。比重不随年龄变化。已繁殖的老年线虫表现出渗透脆性增加，但在未交配的雌虫中未观察到这种变化。将醋酸布氏线虫衰老的特征参数与秀丽隐杆线虫（另一种用于研究生物衰老的线虫模型）的参数进行了比较。
