LDH enzyme activities were determined in atretic and fragmented oocytes. The enzymatic activities in fragmented oocytes and ova were compared to those already known in early rat cleavage stages. Atretic oocytes are totally devoid of LDH activity. However, fragmented oocytes and ova exhibit nearly identical LDH activities to early cleavage stages. This result supports our earlier assumption that fragmentation and cleavage are homologus processes, induced by the same maternally transmitted factors in the oocyte cytoplasm.
在闭锁和碎片化的卵母细胞中测定了乳酸脱氢酶（LDH）的酶活性。将碎片化卵母细胞和卵子中的酶活性与大鼠早期卵裂阶段已知的酶活性进行了比较。闭锁卵母细胞完全没有LDH活性。然而，碎片化卵母细胞和卵子的LDH活性与早期卵裂阶段几乎相同。这一结果支持了我们早期的假设，即碎片化和卵裂是同源过程，由卵母细胞细胞质中相同的母源传递因子诱导。
