Chronic administration of Bauhinia forficata link reduced exploratory activity without affecting blood glucose in healthy rats. Repositório Alice
MORANZA, H. G.; SCANAVACA JUNIOR, L.; MATAQUEIRO, M. I.; QUEIROZ-NETO, A. de; FERRAZ, G. C..
Abstract: This study provides information about the effect of chronic ingestion of a decoction of Bauhinia forficata on the behavior of rats. The aim of this study was to investigate the exploratory activity, anxiety level, and blood glucose of healthy rats submitted to prolonged treatment with a decoction of B. forficata. Twenty male rats, aged two months and weighing approximately 145g were randomly distributed into two groups. The Bauhinia group freely ingested a decoction of B.forficata for 4 weeks, while the control group received water. Body weight, food and fluid intake, and glycemic index were quantified. The open field (OF) and elevated plus maze (EPM) tests were applied at the end of the experiment. Data were analyzed by Student?s t test for...

Effects of elevated calcium on motor and exploratory activities of rats BJMBR
Godinho,A.F.; Trombini,T.V.; Oliveira,E.C..
The effects of serum and brain calcium concentration on rat behavior were tested by maintaining animals on either distilled water (N = 60) or water containing 1% calcium gluconate (N = 60) for 3 days. Animals that were maintained on high calcium drinking water presented increased serum calcium levels (control = 10.12 ± 0.46 vs calcium treated = 11.62 ± 0.51 µg/dl). Increase of brain calcium levels was not statistically significant. In the behavioral experiments each rat was used for only one test. Rats that were maintained on high calcium drinking water showed increased open-field behavior of ambulation (20.68%) and rearing (64.57%). On the hole-board, calcium-supplemented animals showed increased head-dip (67%) and head-dipping (126%), suggesting...

Food deprivation reduces social interest in the European sea bass Dicentrarchus labrax ArchiMer
Aimon, Cassandre; Le Bayon, Nicolas; Le Floch, Stephane; Claireaux, Guy.
Periods of food deprivation up to several months are common features for fishes and in such conditions, fitness will be determined by their capacity to maximize food encounter while minimizing predation risk. In this context, the propensity to take risk and the willingness to associate with conspecifics are particularly important as they contribute to alleviating the trade-off between predation avoidance and foraging efficiency. This study examined to what extent food deprivation modulates fish risk-taking and social behaviours, as well as the relationship between them. To address these issues juvenile European sea bass were either fed daily with a maintenance ration or food-deprived during 3 weeks. Risk-taking and sociability were assessed through...
