Dual effects of hyperprolactinemia on carrageenan-induced inflammatory paw edema in rats.

Objectives: The effects of short-term 5-day and long-term 30-day hyperprolactinemia induced by domperidone (1.7 mg/kg/day, s.c.

Behavioural and gill histopathological effects of acute exposure to sodium chloride in moneda (Metynnis orinocensis).

To evaluate the toxicity of sodium chloride (NaCl), juveniles and adult Metynnis orinocensis were exposed for 96h to 0, 5, 10, 15, 20 or 40gL(-1) of salt. Food intake, behaviour, opercular frequency (OF), mortality, body weight and gill microscopic alterations were evaluated. Behavioural changes were observed in fish exposed to concentrations higher than 10gL(-1).

Pimozide injections into the Nucleus accumbens disrupt maternal behaviour in lactating rats.

In rodents ongoing maternal behaviour requires activation of dopamine receptors. Therefore, it is possible that some motor components of maternal behaviour might be mediated by concurrent dopaminergic stimulation. It has been previously demonstrated that peripheral injections of some antipsychotic drugs such as pimozide have disruptive effects on maternal behaviour.
