Note. Means with capitalized letters differ at p ≤ 0.01 while lowercase letters differ at p ≤ 0.05. Different letters indicate differences as follows: S(s) indicates groups significantly different from respective saline control, U(u) indicate groups significantly different from UN treated dams, C(c) indicates significant difference from cocaine treated groups (CC and IC). W(w) indicates significant within group differences between days 5 and 10.
