We examined the effect of glial cell line-derived neurotrophic factor (GDNF) upon nigrostriatal dopaminergic function in response to two-pulse potassium (K(+)) stimulation in rats under in vivo microdialysis conditions. The two-pulse infusion protocol permits us to focus upon the role of this neurotrophin as related to vesicular storage and release of(More)
The influence of brain-derived neurotrophic factor (BDNF) upon the nigrostriatal dopaminergic system was evaluated in weanling and adult mice carrying a targeted inactivated BDNF gene. Regional specificity of this BDNF mutation was assessed by assaying catecholamine concentrations within the corpus striatum, hypothalamus, and olfactory bulbs. In weanling(More)
In the present report we examined the differences in in vitro dopamine (DA) and dihydroxyphenylacetic acid (DOPAC) efflux from the corpus striatum (CS) of intact versus 6-hydroxydopamine (6-OHDA) lesioned (in substantia nigra) male rats in response to different doses of two pulse infusions of L-dihydroxyphenylalanine (L-DOPA). In the first experiment, we(More)
The aim of the present study was to detect the expression of resistin in rats with acute pancreatitis (AP) and investigate its significance in the pathogenesis of AP. In total, 40 Sprague‑Dawley rats were randomly divided into four groups (n=10), including the normal control, sham‑operated, acute edematous pancreatitis (AEP) and acute necrotizing(More)
We examined the effect of L-dihydroxyphenylalanine (L-DOPA) infusion in vitro upon dopamine (DA) and dihydroxyphenylacetic acid (DOPAC) output from superfused corpus striatum of vehicle and reserpine or tetrabenazine (TBZ) treated male rats. Specifically, we tested the effects of two 20-min infusions of L-DOPA (5 uM) upon DA and DOPAC output (pg/mg/min) in(More)
