A number of pre-clinical studies have shown that brain-generated acetaldehyde, the first metabolite of ethanol, exerts reinforcing effects that promote the acquisition of ethanol intake, while chronic intake maintenance appears to be mediated by alco

The effect of manganese on free polysomal protein synthesis of immature rat brain (3 weeks old) has been determined after 1, 2, 3, and 4 weeks of daily intake of 55 micrograms manganese/ml of drinking water. The protein synthesis was inhibited up to

Nuclear and cytosolic fractions of rat uteri and tissues from the central nervous system contain proteins that are recognized by a polyclonal tyrosinase antibody. This antibody eliminates the cresolase activity of uterine nuclear extract when estradi

The sigma binding sites are postulated to be involved in various central nervous system (CNS) disorders. The neuroleptic drug, haloperidol, displays high affinity for these receptor sites in the CNS. In the present study the effect of repeated exposu

The possible role of Ca2+ influx in alpha 1-adrenoceptor-stimulated [3H]inositol phosphate [( 3H]InsP) formation was examined in primary cultures of glial cells from 1-day-old rat brain. The Ca2+ ionophore A23187 caused a concentration- and time-depe

Neurocatin is a small (about 2000 Da) neuroregulator isolated from mammalian brain. Earlier it was shown that addition of nanomolar concentrations of neurocatin to synaptosomes isolated from rat brain increased levels of serotonin and decreased catab

Hydroxylation and N-methylation of three potent alpha 2-adrenoceptor agonists detomidine, medetomidine and dexmedetomidine by rat brain, kidney, liver and lung were studied in vitro. NADPH-dependent hydroxylation of the 3'-methyl group was catalyzed

Both 3-day and 15-day desipramine treatments (10 mg/kg, once daily) significantly reduced beta 1- but not beta 2-adrenoceptor and isoproterenol-stimulated adenylyl cyclase activities in rat cortical, hippocampal and amygdaloid membrane preparations.

A cannula for repeated intracerebroventricular (ICV) infusion was implanted stereotaxically in 16 male Sprague-Dawley rats. Subsequently, an alcohol preference test was given to each animal to establish its preferred concentration in the presence of

Rats were chronically exposed to cigarette smoke for 20 min twice daily using a smoking machine. On days 1, 4, and 14, locomotor activity and rearing were measured for 15 min in an open-field apparatus. On day 1, exposure to cigarette smoke increased
