Vitamin D (calcitriol) is a nuclear transcription regulator acting via a nuclear hormone receptor (VDR). In addition to its role in the regulation of calcium and phosphate horneostasis and in bone formation, Vitamin D is also thought to be involved in brain function. The aim of this study was to behaviourally phenotype VDR knockout mice. We characterized the behaviour of VDR null mutant mice and wildtype littermate controls by subjecting them to a range of tests including a primary behavioural screen (using the SHIRPA protocol), rotarod, gait analysis, Y-maze, marble burying test, bedding test, holeboard test, elevated plus maze, open field test and prepulse inhibition of the acoustic startle response. There were no effects of genotype on most of the scores from the SHIRPA protocol except that VDR -/- mice had alopecia, were shorter and weighed less than VDR +/+ mice. VDR -/- mice had a shorter gait as well as impairments on the rotarod, in the bedding test and impaired habituation in both the open field and on the acoustic startle response. The VDR -/- mice had normal acoustic startle responses but had impaired PPI at long (256 ms) but not short (64 ms) prepulse to pulse intervals. The VDR -/- mice were less active in the open field and buried fewer marbles in the marble burying test. However, there were no differences in the time spent on the open arms of the elevated plus maze or in working memory as assessed by repeat arm entries on the Y-maze. Therefore, it appears that VDR -/- mice have muscular and motor impairments that significantly affects locomotor behaviour but seemingly no impairments in cognition as indicated by exploration, working memory or anxiety.

Apesar de várias evidências do potencial terapêutico dos óleos essenciais em diversas patologias, inclusive em transtornos mentais, os estudos científicos que comprovam esse potencial ainda são escassos. O objetivo deste trabalho foi investigar e comparar de forma sistemática os efeitos dos óleos essenciais de alecrim (Rosmarinus officinalis) e petitgrain (Citrus aurantium L.) em modelos animais com ratos nos seguintes parâmetros: atividade motora, depressão, ansiedade e aprendizado. Método: foram utilizados 297 ratos em todo o estudo, sendo: 54 no piloto 1; 66 no piloto 2; 36 no campo aberto; 36 na esquiva discriminativa; 36 no teste de enterrar esferas; 33 na natação forçada e 36 no experimento de aprendizagem. Os principais resultados revelaram que: ratos tratados com 100mg/kg (i.p.) de óleo essencial de alecrim não apresentaram diferença na atividade motora avaliada em campo aberto (p=0.213 teste de Mann-Whitney), tampouco na aprendizagem da resposta de pressão à barra em caixa de Skinner (p=0.098 teste de Mann-Whitney), comparados aos ratos controles que receberam salina 0,9% (1 mL/kg), porém esse mesmo tratamento foi efetivo em modelos de depressão (p=0.006 teste de Mann-Whitney) e ansiedade (teste de esconder esferas - p=0.003 ANOVA). No que diz respeito ao óleo essencial de petitgrain administrado em ratos na dose de 30mg/kg (i.p.), não observou-se diferença na atividade motora (p=0.795 teste de Mann-Whitney), contudo obteve-se efeito ansiolítico (teste de esconder esferas - p=0.028 ANOVA) e antidepressivo (p=0.001 teste de Mann-Whitney) em relação ao controle. Ademais, o óleo de petitgrain proporcionou uma melhora na aprendizagem (p=0.002 teste de Mann-Whitney) se comparado com os animais do grupo controle e os animais tratados com alecrim. Dessa forma podemos concluir que ambos os óleos estudados (alecrim e petitgrain) apresentaram atividades ansiolítica e antidepressiva nos testes realizados e apenas o óleo de petitgrain produziu efeitos na aprendizagem dos animais.
