Dopamine (DA) content in the median eminence (ME), and in the anterior (AH), mediobasal (MBH) and posterior hypothalamus (PH) in the adult control group, MTX-treated rats, L-NAME-treated animals and MTX plus L-NAME-treated rats. The values are expressed as mean ± S.E.M. (n = 8 in each group). *P ≤ 0.05; **P ≤ 0.01 and ***P ≤ 0.001 vs. control group; ^#P ≤ 0.05 and ^##P ≤ 0.01 vs. MTX group; ^&&P ≤ 0.01 and ^&&&P ≤ 0.001 vs. L-NAME group.
