Decreased body weight gain. Weight gain throughout the experimental period for the three groups of rats under study: saline (n=18), K 5mg (ketamine 5 mg/kg, n=17) and K 10mg (ketamine 10 mg/kg, n=17). Each point represents the mean ± standard error of body weight in a given day. Since day 3, animals treated with either dose of ketamine displayed significantly decreased weight gain as determined by the Turkey HSD for unequal N test. The arrow indicates the end of the administration period.
