1. Efeitos comportamentais da Dietilpropiona e Cocaína em primatas não-humanos (Callithrix penicillata) após administração sistêmica de antagonistas dos receptores de 5-HT1A e NK3
Há muitos anos vinha sendo atribuído, exclusivamente, ao sistema dopaminérgico o papel de mediar os efeitos comportamentais da cocaína. Isso se deveu à descoberta de que a cocaína se liga ao transportador de dopamina e, assim, bloqueia a recaptação da mesma na fenda sináptica. Conseqüentemente, tem-se um aumento da concentração extracelular de do

2. Tachykinin-induced activation of non-specific cation conductance via NK3 neurokinin receptors in guinea-pig intracardiac neurones.
1. Whole mount preparations from guinea-pig hearts were used to characterize the receptors and ionic mechanisms mediating the substance P (SP)-induced depolarization of parasympathetic postganglionic neurones of the cardiac ganglion. 2. Measurement of the amplitude of depolarization in response to superfusion of different tachykinin agonists (neurokinins A (

3. Electrical stimulation of the mucosa evokes slow EPSPs mediated by NK1 tachykinin receptors and by P2Y1 purinoceptors in different myenteric neurons
Slow excitatory postsynaptic potentials (EPSPs) in enteric neurons arise from diverse sources, but which neurotransmitters mediate specific types of slow EPSPs is unclear. We investigated transmitters and receptors mediating slow EPSPs in myenteric neurons evoked by electrical stimulation of the mucosa in guinea pig small intestine. Segments of ileum or jeju
