- Learning deficits and suppression of the cell proliferation in the hippocampal dentate gyrus of offspring are attenuated by maternal chewing during prenatal stress.

Chewing under stressful conditions prevents stress-induced behavioral impairments and morphologic changes. Here, we examined whether chewing during prenatal stress prevents the stress-induced learning deficits and the suppression of cell proliferation in the hippocampal DG in adult offspring. Pregnant mice were exposed to restraint stress beginning on day 12 of pregnancy and continuing until delivery. Half of the dams were given a wooden stick to chew on during restraint. The pups were raised to adulthood, and learning ability and cell proliferation in the hippocampal DG were assessed. In dams, chewing during prenatal stress attenuated the stress-induced increase in plasma corticosterone levels. In the adult offspring, prenatal stress impaired learning and decreased cell proliferation in the DG, whereas maternal chewing during prenatal stress significantly attenuated the prenatal stress-induced learning deficits and decreased cell proliferation in the DG in their offspring. These findings suggest that maternal chewing during prenatal stress is an effective stress-coping method for the dam to prevent learning deficits and suppression of cell proliferation in offspring.

- Effect of water deprivation on baseline and stress-induced corticosterone levels in the Children's python (Antaresia childreni).

Heretofore, the impact of water deprivation on CORT plasma levels has not been thoroughly investigated. However, both baseline CORT and stress-induced CORT are expected to respond to water deprivation not only because of hydric stress per se, but also because CORT is an important mineralocorticoid in vertebrates. We assessed the effects of water deprivation on baseline CORT and stress-induced CORT, in Children's pythons (Antaresia childreni), a species that experiences seasonal droughts in natural conditions. We imposed a 52-day water deprivation on a group of unfed Children's pythons (i.e., water-deprived treatment) and provided water ad libitum to another group (i.e., control treatment). We examined body mass variations throughout the experiment, and baseline CORT and stress-induced CORT at the end of the treatments. Relative body mass loss averaged ~10% in pythons without water, a value 2 to 4 times higher compared to control snakes. Following re-exposition to water, pythons from the water-deprived treatment drank readily and abundantly and attained a body mass similar to pythons from the control treatment. Together, these results suggest a substantial dehydration as a consequence of water deprivation. Interestingly, stress-induced but not baseline CORT level was significantly higher in water-deprived snakes, suggesting that baseline CORT might not respond to this degree of dehydration. Therefore, possible mineralocorticoid role of CORT needs to be clarified in snakes. Because dehydration usually induces adjustments (reduced movements, lowered body temperature) to limit water loss, and decreases locomotor performances, elevated stress-induced CORT in water-deprived snakes might therefore compensate for altered locomotor performances. Future studies should test this hypothesis.
