Double Thiry-Vella loops in calves were used to show that when heat stable E coli enterotoxin was in contact with only one of the loops, a net increase in water secretion occured in both. It was concluded that either enterotoxin itself or a mediator substance was absorbed and acted via the systemic circulation.
在小牛身上使用双三十维拉袢来表明，当热稳定的大肠杆菌肠毒素仅与其中一个袢接触时，两个袢中的水分泌都出现净增加。得出的结论是，要么肠毒素本身，要么一种介质物质被吸收并通过体循环起作用。
