一些研究人员的结果表明，从青蛙膀胱收集的尿液永远不会比同一动物的血液高渗。其他研究人员发现染料集中在青蛙的肾脏中。膀胱可能在尿液的最终浓度中发挥一定作用的可能性导致了以下实验：确认将泄殖腔绑在自来水中的阿道夫（'27）青蛙的重量会增加，并且这种重量的增加大约等于膀胱中尿液的积累。当将泄殖腔绑住并在膀胱中积聚尿液的青蛙放入高渗盐溶液或干燥室时，会将这些液体重新吸收到其组织中。将肠结扎以排除通过该途径重吸收的可能性。作者得出的结论是，膀胱可能充当青蛙的供水源，因此从肾脏输送的尿液浓度可能会在膀胱中发生变化。 ||摘要作者： 作者（由 Wistar Biol. Serv. 提供）
The results of some investigators show that urine collected from the frog's bladder is never hypertonic to the blood of the same animal. Other investigators find dyes to be concentrated in the frog's kidney. The possibility that the bladder might play some role in the final concentration of the urine led to the following experiments: Confirming Adolph ('27) frogs with tied cloacae placed in tap-water increase in weight and this increase in weight is approximately equal to the accumulation of urine in the bladder. Frogs with tied cloacae and accumulated urine in their bladders will reabsorb this fluid into their tissues when placed in hypertonic salt solution or dry chamber. The intestine was tied off to rule out the possibility of reabsorption by this route. The author concludes that the bladder may act as a source of water supply for the frog and that thus the concentration of the urine as delivered from the kidney may be altered in the bladder. || ABSTRACT AUTHORS: Author (courtesy Wistar Biol.
