本文报道了用43℃温水加热大白鼠睾丸20分钟后其生精上皮细胞的数量变化。实验结果表明,各类生精细胞对热作用的敏感程序依次为粗线期初级精母细胞、精子细胞、细线前期初级精母细胞;A 型精原细胞及支持细胞所受影响较小;成熟精子及间质细胞不受热作用的影响。损伤在热作用50天后开始恢复。本文还提出了H-E 染色大白鼠生精上皮周期的5期分类法。 This article reports the change in the number of germ-line epithelial cells after heating the rat testis for 20 minutes with warm water at 43 ° C. The experimental results showed that the sensitivity programs of spermatogenic cells to heat were as follows: primary spermatocytes, spermatids and primary spermatocytes in early slender line; the effect of type A spermatogonia and supporting cells was little; Mature sperm and interstitial cells are not affected by heat. Injuries begin to recover after 50 days of heat. This article also proposed a H-E staining rat spermatogenic epithelium cycle 5 classification.
