Water absorption in intestinal segments was monitored by measuring the concentration of polyethylene glycol, a nonabsorbable reference marker, in a balanced salt solution continuously perfused through the lumen. Staphylococcus aureus delta-toxin inhibited water absorption in rabbit jejunum and ileum perfused in vivo and in guinea pig ileum perfused in vitro. Cholera toxin also interfered with water absorption in guinea pig ileum maintained in vitro, but S. aureus enterotoxin B had no demonstrable effect on this tissue.
通过测量聚乙二醇(一种不可吸收的参考标记物)在持续灌流肠腔的平衡盐溶液中的浓度,监测肠段的水吸收情况。金黄色葡萄球菌δ毒素抑制体内灌流的兔空肠和回肠以及体外灌流的豚鼠回肠中的水吸收。霍乱毒素也会干扰体外培养的豚鼠回肠中的水吸收,但金黄色葡萄球菌肠毒素B对该组织没有明显影响。
