That something seems tobe related toan enzyme called catalase .
似乎这与一种叫做过氧化氢酶的酶类有关。
Dr watabe found that the offspring of calorie-restricted mothers have more catalase than those of mothers who were fed without restriction .
watabe博士发现，热量限制的母体的后代含有比那些没有经过限制的母体的后代更多的过氧化氢酶。
If inherited epigenetic changes were causing daughter rotifers to produce more catalase , it would raise the question of whether a similar thing happens in other species and , if so , whether it might be induced artificially , without all the tedious business of a lifetime 's starvation .
