Abstract

The qualitative behaviour of spermatogenetic cells and Sertoli cells in the buffalo (Bubalus bubalis) was studied by identifying 8 stages of the seminiferous epithelium cycle based on meiotic division and morphology as well as the position of more mature spermatids. To achieve better results, stages 1, 2, 3, 4 and 8 were sub-divided. Six peaks of spermatogonial mitosis suggested six generations of spermatogonia. Of these, three were due to A (A1, A2, A3), two to B (B1, B2) and one to intermediate spermatogonia. However, another category of spermatogonia (A0), which divided rarely, were also present at all stages of the cycle. A1, A3, ln-, B1-spermatogonia and secondary spermatocytes showed 20, 18.75, 10.2, 15.5 and 10 p. 100 degeneration, respectively, No degeneration was observed in A2 and B2-spermatogonia, primary spermatocytes or spermatids. The degeneration of these various spermatogenetic cells greatly affected the efficiency of spermatogenesis.

摘要

通过根据减数分裂、形态学以及更成熟精子细胞的位置确定生精上皮周期的8个阶段，研究了水牛（Bubalus bubalis）生精细胞和支持细胞的定性行为。为了获得更好的结果，将第1、2、3、4和8阶段进行了细分。精原细胞有丝分裂的六个峰值表明有六代精原细胞。其中，三代归因于A型（A1、A2、A3），两代归因于B型（B1、B2），一代归因于中间型精原细胞。然而，另一类很少分裂的精原细胞（A0）在周期的所有阶段也都存在。A1、A3、ln-、B1-精原细胞和次级精母细胞的退化率分别为20%、18.75%、10.2%、15.5%和10%。在A2和B2-精原细胞、初级精母细胞或精子细胞中未观察到退化现象。这些不同生精细胞的退化极大地影响了精子发生的效率。
