摘要：We studied the absorption enhancement effects of three types of protease inhibitors, aprotinin, bacitracin and soybean trypsin inhibitor, in the rat intestine. Of these protease inhibitors, bacitracin enhanced the absorption of FD-4 and phenol red from the rat small and large intestine without mucosal toxicity. Thus, it was suggested that bacitracin has not only a protease-inhibitory but also an absorption-enhancing capability.
