The original version of this article unfortunately contained a mistake. The image of Fig. 1 should be corrected. In the previous figure, we had shown that the plasma kallikrein cleaves both high molecular weight kininogen (HMWK) and low molecular weight kininogen (LMWK) to produce bradykinin. However, the plasma kallikrein activates only high molecular weight kininogen (HMWK) while low molecular weight kininogen (LMWK) is activated by tissue kallikrein. Hence we have removed low molecular weight kininogen (LMWK) in the revised figure. We wish to acknowledge Dr. Allen P. Kaplan, Medical University of South Carolina, Charleston, SC, USA for pointing out the error in Fig. 1. The corrected Fig. 1 is given below.

不幸的是，本文的原始版本包含一个错误。图1的图像应进行校正。在上一张图中，我们表明血浆激肽释放酶可裂解高分子量激肽原（HMWK）和低分子量激肽原（LMWK）来产生缓激肽。但是，血浆激肽释放酶仅激活高分子量激肽原（HMWK），而低分子量激肽原（LMWK）被组织激肽释放酶激活。因此，我们在修订后的图中删除了低分子量激肽原（LMWK）。我们要感谢美国南卡罗来纳州查尔斯顿市南卡罗来纳州医科大学的Allen P. Kaplan博士指出了图1中的错误。下面给出了校正后的图1。
