S100B, a calcium-binding protein produced by astroglial cells, mediates paracrine and autocrine effects on neurons and glial cells. It regulates the balance between proliferation and differentiation in neurons and glial cells by affecting protective and apoptotic mechanisms. Post-mortem studies have demonstrated a deficit in synapses and dendrites in brains(More)
The distribution of serotonin (5-HT1) receptors in various cortical regions of the rat brain has been examined during ontogenesis by quantitative autoradiography. An increase in binding site density between the first postnatal day and adult age was observed and could be approximated by a sigmoid shaped (logistic) growth curve. A marked heterochrony in the(More)
RATIONALE Flupentixol (FLX) has been used as a neuroleptic for nearly 4 decades. In vitro data show comparable affinity to dopamine D(2), D(1) and 5-HT(2A) receptors and recently, FLX showed to be not inferior to risperidone in schizophrenic patients with predominant negative symptomatology, which was implicated with flupentixol's interaction with 5-HT(2A)(More)

In pigs, behavioural responses were examined after administration of 8-hydroxy-2-(di-n-propylamino)tetralin (8-OH-DPAT), a full agonist at 5-hydroxytryptamine (5-HT) receptors of the 5-HT1A subtype, and the pyrimidinylpiperazine derivatives ipsapirone and Bay Vq 7813 (2-[4-(2-pyrimidinyl)-1-piperazinylpropyl]-1,2-benzisothiazol-3(2H)one-1,1-dioxide), which(More)
The selective serotonin(5-HT)1A receptor agonists 8-OH-DPAT and ipsapirone were tested in selectively inbred Wistar rats, with high preference [70–90%: defined as the ratio of ethanol (EtOH) to total fluid intake] for EtOH (10% v/v) over water in a two-bottle free choice situation. Rats were injected shortly before the overnight test session(More)
In the present study the costs of schizophrenia in Germany were studied using the "bottom up" prevalence-based method. In a random sample of 180 schizophrenic patients stratified according to the most important care institutions, direct and indirect costs were retrospectively documented for a 12-month period. Depending on the place of recruitment and the(More)
The effects of the anti-inflammatory and analgesic drug 3-ethyl-1-(3-nitrophenyl)-2,4[1H, 3H]-quinazolindione (TVX 2706) on neuronal and glial cell culture systems including neuroblastoma × glioma hybrid cells have been studied. This compound strongly enhances the increase in intracellular levels of cyclic AMP caused by appropriate effectors in all systems(More)
BACKGROUND Multiple sclerosis is a chronic, incurable, demyelinating disease that requires long-term treatment. Rates of non-adherence to prescribed therapy of up to 50% have been reported for chronic diseases. Strategies to improve treatment adherence are therefore of the utmost importance. This study will evaluate the effect of using electronic and paper(More)
OBJECTIVE The primary aim of this paper was to compare the effects of flupenthixol and risperidone on subjective quality of life and attitude towards medication in chronic schizophrenic patients with mainly negative symptoms. In a spectrum ranging from its typical end "haloperidol" to its atypical end "clozapine", flupenthixol has typical and atypical(More)
The efficacy of flupentixol and risperidone were compared in a randomized double-blind study in 153 chronic schizophrenic patients. Flupentixol showed to be not inferior to risperidone concerning schizophrenic negative symptoms at week 8, 16 and 24. Positive symptoms and general psychopathology improved comparably, too. There was a trend in favor of(More)
