Experiments with Heidenhain pouch dogs showed the well known high sodium concentrations at low secretion rates and low sodium concentrations at high ones after stimulation with a continuous intravenous injection of histamine. It was previously thought that the primary secretion did not contain any sodium, but that all the sodium present in the gastric juice appeared as a result of diffusion. A more detailed analysis of the experimental data showed, however, that there is in fact sodium present also in the primary juice in the small concentration of 3-5 mEq/l. The origin of the secreting volume containing this concentration of sodium is unknown.
对海登海因小胃犬进行的实验表明，在用组胺持续静脉注射刺激后，在低分泌速率时钠浓度很高，而在高分泌速率时钠浓度很低，这是众所周知的现象。以前认为初始分泌液中不含任何钠，而是胃液中所有的钠都是扩散的结果。然而，对实验数据的更详细分析表明，实际上初始分泌液中也存在钠，其浓度低至3 - 5毫当量/升。含有这种浓度钠的分泌液量的来源尚不清楚。
