Growth sites within the newborn cartilaginous nasal septum have been identified by monitoring chondrocytic proliferation radioautographically. Tritiated thymidine was the labeling agent used. The results were tabulated and charted graphically; they showed the overall septum to be relatively active mitotically, yielding an average of 3.54 labeled cells per microscopic field counted. However, certain areas showed greater activity than others, namely the anterior tip (4.51 labeled cells/field), the midportion (3.98 labeled cells/field) and the posterior section of the presphenoidal tail (4.24 labeled cells/field).
通过放射自显影监测软骨细胞增殖，已确定新生儿软骨性鼻中隔内的生长部位。使用的标记剂是氚标记胸腺嘧啶核苷。结果被制成表格并以图表形式呈现；结果显示整个鼻中隔在有丝分裂方面相对活跃，每个计数的显微镜视野平均有3.54个标记细胞。然而，某些区域的活性高于其他区域，即前端（4.51个标记细胞/视野）、中部（3.98个标记细胞/视野）和蝶骨前尾的后部（4.24个标记细胞/视野）。
