    Abstract:
    This study was designed to examine the effects of ethanol withdrawal on offspring rats that consumed ethanol during gestation and lactation, in order to examine whether there was an improvement in pancreatic trypsinogen and lipase activities at 2 months postpartum with respect to offspring that fed on ethanol until death. A second purpose for our study was to determine if a folic acid supplement during gestation and lactation was sufficient or insufficient to reverse the negative effects of ethanol consumption. Both genders were used with the aim of investigating any differential pancreatic behaviour. The animals were randomized into five groups: the control group (CG) received water and a basic rat diet during pregnancy, lactation and growth; the ethanol group (EG) was fed an ethanol diet during pregnancy, the suckling period and growth until death; the ethanol-water group's (E+WG) ethanol was eliminated after lactation; The ethanol-folic acid group (E+FG) received a folic acid supplemented diet during pregnancy and the suckling period and in the ethanol+folic acid group (E+FG+FG) this supplementation continued during growth. Our results showed that ethanol administration or ethanol withdrawal did not significantly alter lipase activity in the pancreas. Ethanol administration decreased trypsinogen levels in the pancreas of males and females. However, in males, as opposed to females, the withdrawal of ethanol did not recover the values of pancreatic trypsinogen content, nor did a folic acid supplementation significantly alter the parameters we studied. Our treatment produced no effect on lipase levels. There was a gender-related difference in pancreatic trypsinogen content, the implication being that in future all results on exocrine pancreas function in male and female animals should be analysed separately.
