| The aim of the present study was to evaluate the effects of sodium fluoride (NaF) on the male reproductive system. Adult male rats were exposed to NaF in drinking water for 30 days at three concentrations: 1.54 (control, tap water), 50 and 100 ppm. Body and organ weights, daily sperm production, sperm number and morphology were investigated. No difference was observed on the sperm number and morphology among the groups, as well as body weight and organ absolute and relative weights. Overall, despite the presence of a mild degree of dental fluorosis in the higher dose group, the results indicated that exposure to NaF at the doses used in the present study did not adversely affect sperm production and morphology of male rats. |

| The effect of a compound combining Valeriana officinalis and Passiflora alata extracts was tested on two mouse memory models: habituation and step-through inhibitory avoidance. Diazepam (1.0 and 2.5 mg/kg) was used as a positive control. Acute diazepam (2.5 mg/kg) before training impaired the habituation and performance in the inhibitory avoidance. On the other hand, acute phytotherapeutic compound (40-160 mg/kg), also before the training session, did not alter mouse behavior in these models. Repeated (15 days) treatment with the compound also did not impair the habituation. At the doses used, no locomotor effect was found. Taken together, the results suggest that, contrary to diazepam, the anxiolytic Valeriana officinalis and Passiflora alata compound did... |
