Nitrogen equivalent to about 35 per cent of the nitrogen intake, though not necessarily derived directly from it, is daily secreted in the succus entericus in dogs on a mixed diet; about 10 per cent is excreted in the feces. and about 25 per cent is reabsorbed. The amount of reabsorbed nitrogen-containing material is considerably larger if the bile and pancreatic secretion are included. The metabolic significance of this reabsorption can only be surmised. That it is probably of great importance is indicated by the fact that in the experiments here recorded the amount of nitrogen reabsorbed equaled approximately 25 per cent of the nitrogen intake.
在杂食的狗，每日从肠液分泌出相当于摄入氮量的约 35%的氮，但不一定直接来自摄入的氮；约 10%从粪便中排出，约 25%被重吸收。如果包括胆汁和胰液分泌，则被重吸收的含氮物质的量就大得多。这种重吸收的代谢意义只能推测。从所记录的实验中可以看出，重吸收的氮量约等于摄入氮量的 25%，这表明重吸收的氮可能具有重要意义。
