Medicine Comparing the Effects of Electronic Cigarette Vapor and Cigarette Smoke in a Novel In Vivo Exposure System Anthony N.

Eliason1,3, Abhijit Ghosh1 1Jobst Vascular Research Laboratory, University of Michigan Medical School, 2Department of Engineering, Purdue University, 3Department of Surgery, Section of Vascular Surgery, University of Michigan Health System This protocol describes a method for exposing rodents to electronic cigarette vapor (E-vapor) and cigarette smoke. Exposure chambers are constructed by modifying anesthesia chambers with an automated pumping system that delivers E-vapor or cigarette smoke to rodents. This system can easily be modified to accommodate many experimental endpoints.
