(VEGF) is the major physiologic growth factor in angiogenesis in the developing organism [1,2]. In the retina, VEGF is mainly responsible for the development of the retinal vasculature [3]. In the adult organism, VEGF is foremost considered a pathological factor in the development of choroidal neovascularization in age-related macular degeneration (AMD) or(More)
A modified water-lick conflict paradigm is described, using trained rats for up to 35 weekly test sessions under 48 h of water deprivation. The rats rapidly became maximally suppressed by the punishment. This suppression was attenuated by the anxiolytics lorazepam, diazepam, phenobarbital, and meprobamate. The potentially anxiolytic drug CL 218872 and the(More)
1-Tryptophan was administered to rats pretreated with selective inhibitors of the A and B forms of MAO deprenyl, a selective inhibitor of MAO-B, produced minor changes in behaviour and in the concentrations of apparent 5-HT and 5-HAA in brain. High doses of clorgyline, a selective inhibitor MAO-A, produced a characteristic stereotyped syndrome of(More)
Two different forms of hypermotility produced by the amphetamine derivatives PCA and H 77/77, 5 mg/kg of each, was studied in rats treated s.c. with the new 5-HT uptake inhibitor paroxetine. The substance inhibited the effect of PCA but did not influence that of H 77/77. The 5-HT-uptake inhibitors paroxetine, imipramine, and chlorimipramine were also(More)
PURPOSE Members of the vascular endothelial growth factor (VEGF) family are strongly involved in pathological processes in the retina, such as age-related macular degeneration and diabetic retinopathy. Cells of the retinal pigment epithelium (RPE) constitutively secrete VEGF-A, and the secretion of placental growth factor (PlGF) has also been described. RPE(More)
Rats were kept on a 12-h light-dark cycle. One hour after the light was switched on, physiological saline, (+)-amphetamine 1 mg/kg, and H 77/77 5 mg/kg were injected s.c.; the number of groomings was counted 1-2 h after the treatments. (+)-Amphetamine and H 77/77 produced increased grooming which was antagonized by the tyrosine hydroxylase inhibitor H 44/68(More)
The effect of apomorphine (ap) was investigated in rats kept in a familiar cage; 0.25-5 mg/kg s.c. produced a short-lasting, abnormal hypermotility consisting mainly of locomotion and sniffing without grooming. Ap was administered to rate pretreated s.c. with various drugs. Ap hypermotility was antagonized by 12 neuroleptics from different chemical groups.(More)
