Última EFFECTS OF SCORPION Tityus serrulatus VENOM TOXIN TS-8F ON RAT LEARNING AND MEMORY J. Venom. Anim. Toxins MARUO,V. M.; LEBRUN,I.; DORCE,V. A. C.. Scorpion venom neurotoxins are responsible for toxicity and pharmacological effects. They are active in sodium and potassium channels leading to an increase in the release of neurotransmitters, such as glutamate. Glutamate is found in large quantities in the hippocampus (HPC) and is involved in the long-term potentiation (LTP) induction. The HPC is known to be related to certain kinds of memory. The aim of this study is to evaluate the effects of Tityus serrulatus TS-8F toxin on rat behavior with emphasis on learning and memory. We analyzed the effects of different doses of TS-8F on rat behavior in home cages, open-field (habituation), inhibitory avoidance, T-maze, and hippocampus morphology. In the first two experiments, 0.05µg/animal dose of TS-8F did...

Ano: 2002 URL: http://www.scielo.br/scielo.php?script=sci_arttext&pid=S0104-79302002000100007 Resistance exercise improves hippocampus-dependent memory BJMBR Cassilhas,R.C.; Lee,K.S.; Venâncio,D.P.; Oliveira,M.G.M.; Tufik,S.; Mello,M.T.. It has been demonstrated that resistance exercise improves cognitive functions in humans. Thus, an animal model that mimics this phenomenon can be an important tool for studying the underlying neurophysiological mechanisms. Here, we tested if an animal model for resistance exercise was able to improve the performance in a hippocampus-dependent memory task. In addition, we also evaluated the level of insulin-like growth factor 1/insulin growth factor receptor (IGF-1/IGF-1R), which plays pleiotropic roles in the nervous system. Adult male Wistar rats were divided into three groups (N = 10 for each group): control, SHAM, and resistance exercise (RES). The RES group was submitted to 8 weeks of progressive resistance exercise in a vertical ladder apparatus,...
