title: Determination of halothane ED-50 in Mongolian gerbils (Meriones unguiculatus).
abstract: The effective dose-50 (ED-50) for halothane anesthesia was studied in 45 male Mongolian gerbils at age 12 weeks. Close control of circadian variation and animal temperature was maintained. Regression analysis for the percent of animals moving in response to a standard stimulus revealed an ED-50 of 1.32 volumes %, a concentration that approximates the ED-50 of the rat.
