In Experiment I the effect of imipramine treatment on the unconditioned food intake in dogs was tested. In Experiment II imipramine was injected in dogs in which classical conditioned salivary reflexes had been previously elaborated. Both conditioned and unconditioned salivation were decreased. The differentiation of conditioned salivation to CS+ and CS- was disturbed during the imipramine trea...

High-performance liquid chromatography (HPLC) methods employing ultraviolet (UV) detector are not sufficiently sensitive to measure the low plasma concentrations following single oral dose of imipramine. Therefore, in the present study a simple, rapid and yet sensitive HPLC method with UV detection was developed and validated for quantitation of imipramine in human plasma samples. An efficient ...

The hypercortisolism of melancholic depression is thought to reflect hypothalamic hypersecretion of CRH and may be related to the hyperarousal associated with this syndrome. Although chronic administration of imipramine to experimental animals significantly decreases CRH messenger RNA levels in the paraventricular nucleus, it is generally thought that resolution of hypercortisolism following re...

In the present in vivo study, we have investigated whether inhibitors of the Na(+)/Mg(2+) exchanger quinidine and imipramine influence the development of hypertension and whether this is associated with modulation of mitogen-activated protein (MAP) kinase activation in arteries and kidneys of hypertensive rats. Sprague-Dawley rats were divided into four groups (n =6/group): control (vehicle), a...

Among a series of clinically available psychopharmacological agents chlorproma zine is known to be effective against the reactive or neurotic depressive disorders with little effect on the endogenous depression, while imipramine is described to be very effec tive against the endogenous disorders by activating the psychic processes rather than by sedating. Therefore, the comparison of the pharma...

Ether à go-go (Eag; KV10.1) voltage-gated K+ channels have been detected in cancer cell lines of diverse origin and shown to influence their rate of proliferation. The tricyclic antidepressant imipramine and the antihistamine astemizole inhibit the current through Eag1 channels and reduce the proliferation of cancer cells. Here we describe the mechanism by which both drugs block human Eag1 (hEa...

Burkitt lymphoma is a rare malignancy arising from B cells. Current chemotherapeutic regimens achieve excellent overall survival rates in children, but less impressive rates in adults. There are cases with poor outcome causedby toxic effects of the therapy, tumor lysis syndrome, ormetastatic spreadof lymphomas to the central nervous system. Modulators of reactive oxygen species are currently di...

The effects of a range of antidepressants were investigated on neuronal voltage-gated Na(+) and K(+) channels. With the exception of phenelzine, all antidepressants inhibited batrachotoxin-stimulated 22Na(+) uptake, most likely via negative allosteric inhibition of batrachotoxin binding to neurotoxin receptor site-2 on the Na(+) channel. Imipramine also produced a differential action on macrosc...

The behavior toward mouse was studied under and after chronic imipramine treatment in two groups of cats - non-killers and killers. Imiprarnine facilitated predatory behavior in the non-killers but not in the killers, which is in contrast to results obtained on rats. Imipramine produced a marked decrease of locomotor activity of non-killers tested in open field. The inhibition of locomotion did...
