The activity of the magnocellular neurons (MCNs) of supraoptic nucleus (SON) is regulated by a variety of excitatory and inhibitory inputs. Opioids are one of the important compounds that affect these inputs at SON synapses. In this study, whole-cell patch clamp recording of SON neurons was used to investigate the effect of acute and repeated morphine administration on spontaneous inhibitory an...

allium elburzense ( a. elborzense , alliaceae), a plant rich in saponins, is an edible vegetable in northern iran with a folk background use as antidiabetic which has not yet been examined for this indication. to evaluate the antidiabetic potential of a. elburzense , its hydroalcoholic (hdae) and butanolic extracts (bue) were examined. the acute (1, 2, 3, 4, 8 h) and sub-acute (11 days) effects...

the effects of chronic administration of lithium, on acute toxicity of chlorpromazine (cpz) in male albino mice was studied and the ldso values were determined from dose-probit curves. tfie results showed that in lithium pretrealed animals (anmials consumed drinking water containing 600mg/l lithium chloride for 10 days) the ld50 value (the dose corresponding to probit 5) of cpz increased signif...

the effects of chronic administration of lithium, on acute toxicity of carbamazepine (cbz) in mate albino mice was studied and the ld50 values were determined from dose-probit curves. the results showed that in lithium pretreated animals (animals consumed drinking water contraining 600 mg/l lithium carbonate for 10 days) the ld50 value (the doese corresponding to probit 5) of cbz decreased sign...

objective(s) psychotropic medications produce their effects, in part, through increasing neurotrophin levels in the brain. since studies concerning nerve growth factor (ngf) analysis have been limited in scope, in the current experiments we investigated the effects of diverse psychotropic agents on ngf protein levels in various brain regions of rat. materials and methods male wistar rats receiv...
