Introduction & Objective: Male fertility depends on the proper function of a complex system of organs. Harmful effects of morphine on male reproduction and fertility are well documented. Dopamine facilitates sexual behavior in different animal species. The antagonizing of dopamine D2 receptors with sulpiride was aimed to investigate the interaction of dopaminergic system with morphine-induced i...

We analysed the interaction between the dorsal striatum (motor coordination and planning) and the hippocampus (sensory information processing and integration) during performance of goal-directed tasks. The performance of rats that had been injected with different doses of the D(2)-antagonist Sulpiride into the dorsal striatum was tested in an egocentric 4-arm maze task that tests striatal funct...

The aim of this study was to investigate whether the concomitant administration of the substrates or inhibitors of PEPT1, OCTN1, OCTN2, and P-glycoprotein affects the intestinal absorption of sulpiride in rats. The absorption of sulpiride from rat intestine was decreased by the substrates or inhibitors of PEPT1, OCTN1, and OCTN2. On the other hand, the absorption was increased by the substrates...

Sulpiride and tiapride are often used in the treatment of depression, schizophrenia and psychopathology of senescence, gastric or duodenal ulcers and are also partly excreted by kidney. This work developed a simple and sensitive method for their simultaneous monitoring in human urine based on capillary electrophoresis coupled with electrochemiluminescence detection by end-column mode. beta-Cycl...

We investigated whether the uptake of a specific antipsychotic agent, sulpiride, in Caco-2 cells is mediated by a carrier-mediated system. Caco-2 cell monolayers were cultured in plastic culture dishes and uptake and efflux studies were conducted. The determination of sulpiride was performed by HPLC. At 37 degrees C, sulpiride uptake in pH 6.0 was twice as much as in pH 7.4. At 4 degrees C, how...

HANEW, K., SASAKI, A. and YOSHINAGA, K. Evidence for Endogenous Dopaminergic Control of OH Release in Man. Tohoku J. exp. Med., 1981, 135 (1), 103-108 In order to determine whether or not there is a tonic dopamine (DA) control of GH release, the effect of an anti-dopaminergic agent, sulpiride, on GH secretion was studied in 12 normal subjects. After the administration of sulpiride, serum concen...

The effects of a PRL-stimulating substance (sulpiride) on PRL and PGF2α secretion and on luteal and ovarian follicular dynamics were studied during the estrous cycle in mares. A control group (n = 9) and a sulpiride group (Sp; n = 10) were used. Sulpiride (25 mg) was given every 8 h from Day 13 postovulation to the next ovulation. Repeated sulpiride treatment did not appear to maintain PRL conc...

BACKGROUND Capillary electrophoresis (CE) with tris(2,2'-bipyridyl)ruthenium(II) [Ru(bpy)3(2+)]-electrogenerated chemiluminescence (ECL) detection is a promising method for clinical analysis. In this study, a method combining CE with Ru(bpy)3(2+) ECL (CE-ECL) detection that can be applied to amine-containing clinical species was developed, and the performance of CE-ECL as a quantitative method ...

To find the appropriate dosing period to detect ovarian toxicity, sulpiride, a D2 antagonist was orally dosed to female rats at dose levels of 1, 10, and 100 mg/kg/day daily for 2 or 4 weeks in repeated-dose toxicity studies. In addition, sulpiride at the same dose levels was given to female rats daily during the pre-mating period, mating period, and Days 0-7 of gestation to assess its effect o...
