- Abstract: Local anesthetics at a concentration of 10 mM(procaine and lidocaine) were found to inhibit competitively Ca++ binding to lipidextracted RBC membrane, and also to egg albumin film fixed on cover glasses or impregnated into Whatman filter paper (No. 1). A competitive inhibition by local anesthetics was also found in Ca++ binding to Whatman filter paper which had been pretreated with organic solvents to extract possible contaminated lipids. Therefore, it is suggested that the local anesthetics inhibit Ca++ binding not only to phospholipids but to some macromolecules such as membrane proteins, egg albumin film and filter paper.
