Effects of aging on spinal opioid-induced antinociception.

Initial experiments were conducted to determine whether or not the aging process alters the ability of young, mature, or aged male Fischer 344 rats (5- to 6-, 15- to 16-, and 25- to 26-months-old, respectively) to respond to thermal nociceptive…

Spinal beta-endorphin analgesia involves an interaction with local monoaminergic systems.

beta-Endorphin administered intrathecally (i.t.) in rats produced a dose-dependent elevation in tail-flick latency. Naltrexone administered i.t. as a pretreatment reversed the spinal antinociceptive action of beta-endorphin, suggesting that the…

A single restraint stress exposure potentiates analgesia induced by intrathecally administered DAGO.

In rats, restraint exposure potentiates the magnitude and duration of analgesia following both the peripheral and intracerebroventricular administration of several opioid agonists as compared to non-stressed controls. It has been suggested that the…

Calcium channel blockade attenuates angiotensin II-induced drinking in rats.

Lateral ventricular administration of angiotensin II (ANG II) produces potent dipsogenic effects in water-sated rats. ANG II seems to require functional voltage-gated calcium channels on neurons throughout circumventricular brain sites to exert its…

Attenuation of drinking sweetened water following calcium channel blockade.

Recent reports cite results that both cocaine-induced conditioned place preference and activity stimulation are attenuated by pretreatment with the calcium channel blocker isradipine (ISR) in rats. By blocking voltage-dependent

Increases in the locomotor activity of rats after intracerebral administration of cathinone.

There is a widespread practice among people living in Eastern Africa and Southern Arabia of chewing the leaves of the Khat shrub so as to produce pharmacological effects that are practically indistinguishable from those produced by amphetamine…

Nicotine place preference using the biased method of conditioning.

1. The objective of the experimentation was to determine whether nicotine (NIC, 0.8 mg/kg subcutaneously administered) would produce a conditioned place preference (CPP) in rats confined for thirty min to their less-preferred side in a three…

Place preference for the psychostimulant cathinone is blocked by pretreatment with a dopamine release inhibitor.

1. The objective of Exp. 1 was to determine whether intracerebroventricular (ICV) injection of cathinone CATH (8.0-32 micrograms) would produce a dose-dependent conditioned place preference (CPP) and/or activation in rats. Results indicate that rats…

Psychostimulant-induced activity is attenuated by two putative dopamine release inhibitors.

Centrally administered amphetamine (AMPH), cathinone, (CATH), or cocaine (COC) have each been shown to produce elevated activity in rats and this effect is dose responsive. The question remains whether these psychostimulants share a common mechanism…

Conditioned place aversion following the central administration of a novel dopamine release inhibitor CGS 10746B.

Numerous drugs of abuse that elevate brain extracellular dopamine concentrations by either increasing the firing rate of dopaminergic neurons or producing dopamine release have been shown to reliably condition a preference for place. If dopamine…

The treatment of palmar and plantar warts using natural alpha interferon and a needleless injector.

BACKGROUND: The treatment of palmar and plantar warts is difficult and often frustrating. The need for multiple destructive treatments and recurrences after apparent cure are common. OBJECTIVE: The purpose of this study was to determine if…

Stimulation of MAP kinase pathways after maternal IL-1beta exposure induces fetal lung fluid absorption in guinea pigs.

BACKGROUND: We tested the hypothesis that maternal interleukin-1beta (IL-1beta) pretreatment and induction of fetal cortisol synthesis activates MAP kinases and thereby affects lung fluid absorption in preterm guinea pigs. METHODS: IL-1beta was…

Predictors of epinephrine autoinjector needle length inadequacy.

BACKGROUND: Self-administered epinephrine is the primary out-of-hospital treatment of anaphylaxis. Intramuscular injection of epinephrine results in higher peak plasma concentration than subcutaneous injection. With the prevalence of obesity,…

Concurrent treatment of chronic psoriasis and asthma with ustekinumab.

A 56-year-old woman with a 40-year history of guttate flares of psoriasis associated with stress and infection as well as chronic asthma was treated with subcutaneous injections of ustekinumab, repeated after 1 month and then every 3 months. Her…
