Abstract/OtherAbstract:
We evaluate the influence of different malnutrition paradigms (intra-uterine x extra-uterine) in body and brain weight, in seizure threshold and in hippocampus morphometry, in developing rats. Intra-uterine malnutrition model consisted in reduction by half of the ration offered to pregnant female; extrauterine malnutrition consisted of progressive limitation of lactation, from P2 to P15. Seizure induction was accomplished by exposure to flurothyl, at P15. At the same day animals were sacrificed. Morphometric analysis was based on hippocampal pyramidal and granular cells estimate number, through volume calculation and cellular density. Extra-uterine malnutrition significantly reduced pups body and brain weight, seizure threshold and neuronal number in CA4 region only. Intra-uterine malnutrition reduced neuronal number in CA2, CA4 and DG regions regarding well-nourished and extra-uterine malnourished animals. In CA3, CA4 and dentate gyrus, a significant cell increase was observed in groups exposed to seizures, regarding similar control groups.
