Cytometric analysis of lidocaine-induced cytotoxicity: A model experiment using rat thymocytes

Lidocaine is a local anesthetic possessing both lipophilic and hydrophilic properties. It also acts as a surfactant. Thus, the disruption of membranes, resulting in necrosis, is one of possible mechanisms for lidocaine-induced cytotoxicity. However, lidocaine is reported to induce apoptosis. Therefore, in order to compare two mechanisms for cell death induced by lidocaine, the effects of millimolar lidocaine were examined on rat thymocytes by a...
