Absorption of electrolytes and water from the human rectum was quantified by sequential sampling of physiological solutions instilled into the rectum and by the method of continuous intraluminal perfusion. The absorptive function of the rectum measured by the perfusion technique was also compared with that of the entire large intestine. The rectum did not absorb sodium, chloride, or water from isotonic solutions, even after 90 minutes of exposure. The remainder of the colon effectively absorbed sodium, chloride, and water at a rate of approximately 1% of the infused load per minute of contact between perfusates and mucosa.
通过对注入直肠的生理溶液进行连续采样以及采用腔内连续灌注法，对人体直肠中电解质和水的吸收进行了定量分析。还将通过灌注技术测得的直肠吸收功能与整个大肠的吸收功能进行了比较。即使在暴露90分钟后，直肠也不会从等渗溶液中吸收钠、氯或水。结肠的其余部分以灌注液与黏膜接触每分钟约1%的注入量的速率有效吸收钠、氯和水。
