The effects of ethanol dependence and withdrawal on pituitary hormone content and corticosterone release were investigated in AKR/J male mice in a vapor chamber. Both chronic ethanol inhalation and ethanol withdrawal were associated with increased adenohypophyseal-adrenocortical activity. Operationally, ethanol exposure was a stressor. Both physical dependence and withdrawal led to increased secretion/synthesis ratios of peptide hormones. The temporal pattern of pituitary ACTH-IR content changes was different from that of β-endorphin-IR and α-MSH-IR. Differences in the pattern of ACTH-IR and α-MSH-IR most probably represent lobe-specific differences in the response to chronic ethanol exposure and withdrawal.
