متن کاملChronic oral l-DOPA increases dopamine and decreases serotonin excretions.
Given the common pathways for uptake and synthesis for dopamine and serotonin, enhanced renal dopamine synthesis in response to increased substrate 3,4-dihydroxyphenylalanine (l-DOPA) is postulated to decrease renal serotonin synthesis. The present study compared the effects of chronic oral administration ofl-DOPA on dopamine and serotonin excretion in vivo, with the effects of enhanced dopamin...
متن کاملLiriodenine inhibits dopamine biosynthesis and L-DOPA-induced dopamine content in PC12 cells.
The inhibitory effects of liriodenine, an aporphine isoquinoline alkaloid, on dopamine biosynthesis and L-DOPA-induced dopamine content increases in PC12 cells were investigated. Treatment of PC12 cells with 5-10 microM liriodenine significantly decreased the intracellular dopamine content in a concentration-dependent manner (IC50 value, 8.4 microM). Liriodenine was not cytotoxic toward PC12 ce...
متن کاملLiquid chromatographic method for monitoring therapeutic concentrations of L-dopa and dopamine in serum.
We describe a new method for the simultaneous assay of 3,4-dihydroxyphenylalanine (L-dopa) and dopamine in serum. Both compounds have been determined quantitatively at concentrations as low as 10 mug/liter with a coefficient of variation of less than 4%. Peak heights were linearly related to concentration up to 10 mg/liter for each compound. Assay of human sera gave within-run and day-to-day co...
متن کاملActivation of dopamine cell firing by repeated L-DOPA administration to dopamine-depleted rats: its potential role in mediating the therapeutic response to L-DOPA treatment.
The administration of L-dihydroxyphenylalanine (L-DOPA) to patients with Parkinson's disease is known to produce acute effects that include the reduction of rigidity as well as delayed therapeutic actions involving the resumption of complex motor behavior. In order to examine the potential role of dopamine (DA) cell activity in mediating these responses, the effects of acute and repeated L-DOPA...
