Abstract
- Studies are reported of total intestinal perfusion in man in which data relating to the absorptive capacity for water and sodium, flow rate transit time and intestinal volume have been obtained.2. A 'bolus' of radiosodium added to the steady-state perfusion has allowed measurement of bidirectional fluxes of sodium ion across the mucosa to be determined.3. The values obtained agree closely with those that can be predicted from small segmental studies reported in the literature.4. Increasing absorption capacity with increasing flow rate does not seem to reflect a true increase in absorption per unit of intestine but rather a progression to more nearly continuous flow conditions.
摘要
报告了对人体进行全肠道灌注的研究，从中获得了与水和钠的吸收能力、流速、转运时间及肠道容积相关的数据。
向稳态灌注中添加的“放射性钠团注”使测定钠离子跨黏膜的双向通量成为可能。
所获得的值与文献中报道的小段研究预测的值非常吻合。
随着流速增加吸收能力增强，这似乎并非反映单位肠道吸收的真正增加，而是向更接近连续流动状态的进展。
