Planarians developing from isolated regenerates, when pretreated with epinephrine at different periods of their second regeneration, show a higher rate of sugar uptake than the controls, which were not treated with epinephrine. The hormone receptor development can be influenced most effectively by pretreatments performed during the 1--3 and 6--9 day periods, though some effect can be evoked at any time in the course of the second regeneration. The head regenerates developing from the anterior end of the original midpiece (and regenerating tails the second time, B1) were found to be most sensitive, while the similar regenerates developing from the hindpiece of the original planarian (C) showed the weakest reactivity. The experiments provide further evidence that the hormone receptors' activity can be amplified in the course of regenerative development, leading thus--at a later stage--to a more intense sugar uptake response of the cells.
从孤立再生体发育而来的涡虫，在其第二次再生的不同时期用肾上腺素预处理后，其糖摄取率高于未用肾上腺素处理的对照组。激素受体的发育在第1 - 3天和第6 - 9天进行预处理时受到的影响最为显著，不过在第二次再生过程中的任何时候进行预处理都能产生一些效果。发现从原始虫体中段前端发育而来的头部再生体（以及第二次再生尾巴，B1）最为敏感，而从原始涡虫后段发育而来的类似再生体（C）的反应性最弱。这些实验进一步证明，激素受体的活性在再生发育过程中可以增强，从而在后期导致细胞对糖摄取的反应更为强烈。
