It has been previously shown that rats self-administering cocaine under long-access conditions (6 h daily) display(More)

Rat fetal adrenal cortex ultrastructure was studied in fetuses of 20 days of gestation coming from control (C) pregnant rats and from mothers undergoing two experimental conditions: maternal bilateral adrenalectomy on day 1 of gestation (ADX) and maternal bilateral adrenalectomy plus posterior dexamethasone administration the days 15, 16 and 17 of gestation(More)
