The sedative effects of nicotinamide on gerbil wheel-running activity

Summary The activity of 5 groups of gerbils was monitored over 22 days. 3 of the groups received daily injections of nicotinamide (125, 250 or 500 mg/kg) and a 4th group received saline. The 5th group was untreated. The results indicated that both the 250 and 500 mg/kg nicotinamide administrations greatly reduced the activity levels of the gerbils.This work was supported in part by Faculty Research Grant No. 82-6209 from the University of Alabama in Birmingham to J.M.B.
