    Streszczenie angielskie: We report that the intraperitoneal injection of Clostridium perfringens alpha-toxin into mice induces ascites. This phenomenon was monitored by measuring fluid volume and analyzing hematologic data. The mouse toxicity test provides a simple and useful model for examining C. perfringens alpha-toxin-induced vascular permeability.

    Streszczenie angielskie: Swallowing disorders are a serious problem occurring in association with cerebrovascular disorder, nerve or muscle disease, laryngeal or esophageal disease, or advanced age. Unfortunately, it is difficult to evaluate swallowing disorders quantitatively. For this reason, we previously proposed a new method, impedance pharyngography (IPG), for evaluating swallowing disorders noninvasively by measuring neck electrical impedance during swallowing. In this study, the efficacy of this method was tested in a cohort of patients with IPG and healthy controls. The change of neck electrical impedance in the pharyngeal phase is mainly caused by the changes in the equivalent cross-sectional area of the near epiglottis. In addition, the increase in equivalent cross-sectional area due to raising of the larynx caused a decrease in neck electrical impedance in the pharyngeal phase. In the case of healthy subjects, IPG results were highly reproducible, and the patterns were simple and similar. In subjects with advanced age, IPG are delayed-action, slowly changing and less reproducible, and showed various patterns among the subjects. In subjects with swallowing disorders IPG results were less reproducible and showed irregular variable patterns. We therefore conclude that the IPG pattern can be used effectively as a simple index of swallowing activity.
