Lm. Garciamoreno et al., EFFECTS OF ETHANOL AND DIAZEPAN ON AG-NOR NEURONAL-ACTIVITY IN THE MEDIAL MAMMILLARY NUCLEUS, Psicothema, 5(1), 1993, pp. 125-134
It is intended here to study the disorders produced on mammillary bodi
es at both behavioural and morphological levels after diazepam and alc
ohol administration. For this purpose, 3 groups of rats were used, tes
ting them in the water T-maze trial. One of the groups was treated wit
h diazepam, another group alcoholized and the third was control group.
The reaction time was recorded and also the errors commited in the la
st day. Histological analysis was made by evaluation of the number of
Ag-NORs and the surface of these in each neuronal nucleus. The results
show a statistically significant decrease in reaction time throughout
the learning period, with almost no errors. There are not any differe
nces in the estimated NOR surface of the experimental groups. However,
differences were reported concerning the number of NOR quantified amo
ng the different treated groups in relation to control group.
