Contractile vacuole function in amoebae treated with immobilizing (5 mM) and nonimmobilizing (0.125 mM) concentrations of ATP has been studied. In ATP-immobilized amoebae, most vacuolar parameters are accelerated, especially the rate of output which passes from 30 to 70 micron3/sec. This favors the concept of an autonomous vacuole, fully functional in the absence of any bulk contribution to it from remote points of the cell. A lower concentration of ATP (0.125 mM), which does not inhibit movement, causes a still greater acceleration of vacuolar function. Work is in progress to elucidate the site and mode of action of exogenous ATP on Amoeba.
研究了用固定浓度（5 mM）和非固定浓度（0.125 mM）的ATP处理的变形虫中收缩泡的功能。在ATP固定的变形虫中，大多数液泡参数加快，尤其是输出速率从30立方微米/秒增加到70立方微米/秒。这支持了自主液泡的概念，即在没有细胞远端任何大量贡献的情况下，液泡仍能充分发挥功能。较低浓度的ATP（0.125 mM）不抑制运动，但会使液泡功能加速得更明显。目前正在进行研究，以阐明外源ATP对变形虫的作用位点和作用方式。
