当用δ-内毒素处理桑螺时，血淋巴中K+水平在处理后约10分钟开始升高。无论是K+，Na+，Ca ~（2+），或Mg ~（2+）积累在肠组织中的第一个10分钟内毒素后，每口，也不是在肠道组织中检测到的K+翻转率的变化。由于已知葡萄糖蓄积在给药后1 min内被显著刺激，并在5 min内被最大程度刺激（Fast和Donaghue，1971），因此数据表明δ-内毒素不作为离子载体。
WhenBombyx morilarvae are dosed with δ-endotoxin, the level of K+in hemolymph begins to increase about 10 min after treatment. Neither K+, Na+, Ca2+, or Mg2+were accumulated in gut tissue during the first 10 min after toxin was given per os, nor was a change in the rate at which K+turns over in the gut tissue detected. Because glucose accumulation is known to be significantly stimulated within 1 min and maximally stimulated within 5 min after dosing (Fast and Donaghue, 1971) the data suggest that δ-endotoxin does not act as an ionophore.
