The antipsychotic drug prochlorperazine was screened in vitro for possible antimicrobial property against 157 strains of bacteria, belonging to gram positive and gram negative genera. The minimum inhibitory concentration (MIC) of prochlorperazine was determined by agar dilution method, which ranged from 25 to 200 microg/ml with respect to most of the strains. Based on such findings, a further s...

The sensitivity of neurones in the cingulate cortex of the rat to iontophoretically applied substance P (SP) was tested one hour after a single dose of various antidepressant drugs and also 1 day following the termination of a chronic dosing schedule (14 once daily injections) of the same agents. One hour after a single injection of desipramine (DMI), chlorimipramine (CMI), trimipramine (TMI) o...

AIM To investigate the incidence of dyslipidemia (hypertriglyceridemia and hypercholesterolemia) in patients treated with antipsychotics of new generation compared to conventional therapy. METHODS This retrospective study included 116 chronic psychiatric patients divided into two groups: a test group who were on treatment with antipsychotics of the new generation and a control group who were ...

AIM To determine if atypical antipsychotic agents reduce the rehospitalization rates of patients with newly diagnosed or chronic schizophrenia in comparison with typical antipsychotic drugs. METHODS From January 1, 2003, to December 31, 2004, we retrospectively compared two-year rehospitalization rates of 135 patients with newly diagnosed schizophrenia and 398 patients with chronic schizophre...

Two classes of compounds which bind to calmodulin in a calcium-dependent manner (neuroleptic drugs and local anaesthetics) were used to investigate the possible involvement of a calcium-dependent regulator protein in the action of the plant hormones cytokinins.The cytokinin-induced synthesis of betacyanin in Amaranthus tricolor seedlings was used as one test system. The calmodulin antagonists i...

ATP binding to dnaA protein is essential for its action in initiating the replication of plasmids that bear the unique origin of the Escherichia coli chromosome (oriC). ADP bound to that site renders dnaA protein inactive for replication. Diphosphatidylglycerol (cardiolipin), a diacidic membrane phospholipid, displaces the bound nucleotide, and in the presence of components that reconstitute re...
