epinephrine/cannabis

Intravenous injection of 10 mg/kg anandamide reduces the incidence and duration of epinephrine-induced arrhythmias in rats. SR141716A and SR144528, antagonists of cannabinoid receptor I and II did not abolish the antiarrhythmic effect of anandamide. These data suggest that the antiarrhythmic effect

Intravenous injection of the selective cannabinoid receptor agonist HU-210 in doses of 0.05 and 0.25 mg/kg increased heart resistance to arrhythmogenic effects of epinephrine, while intracerebroventricular infusion of this substance had no effect on the incidence of epinephrine-induced arrhythmia.

OBJECTIVE To compare plasma catecholamine concentrations between cocaine-exposed and unexposed term newborns and to determine the relationship between plasma catecholamines and newborn behavior. METHODS Forty-six newborn infants participating in a prospective study of the neonatal and long-term

We have examined the effects of psychoactive and non-psychoactive cannabinoids on isolated immature rat Sertoli cells cultured in either serum-free or serum-containing media. Lactate accumulation by Sertoli cells in serum-free control cultures was 10 fold greater than the values obtained in control

A comprehensive review of the established physiologic and metabolic effects of marijuana in relation to cardiovascular physiology and stress-response mechanisms has been presented. This information is related to the preoperative and postoperative treatment of the dental patient who smokes marijuana

Cannabis, commonly known as marijuana, is the most frequently used illicit drug in Australia. Therefore, oral health care providers are likely to encounter patients who are regular users. An upward trend in cannabis use is occurring in Australia, with 40 per cent of the population aged 14 and above

OBJECTIVE We investigated the influence of type one cannabinoid receptor (CB1) deficiency on acute heart failure (AHF) and the underlying mechanism. Acute heart failure syndrome is an important clinical problem because of its high morbidity and mortality rates. Activation of CB1 induces vascular

This study assessed the acute physiologic effects over time of (co)administration of Delta9-tetrahydrocannabinol (Delta9-THC) (the main psychoactive compound of cannabis) and 3,4-methylenedioxymethamphetamine (MDMA or "ecstasy") in 16 healthy volunteers. Pharmacokinetics and cardiovascular,

The cannabinoid (CB1) receptor agonist HU-210 (0.5 mg/kg, i.v.) exhibited a pronounced antiarrhythmic effect in rats with the adrenaline (epinephrine) and aconitine induced arrhythmia models. At the same time, the intracerebrovascular introduction of HU-210 (500 or 5000 ng) did not affect the

We have found that intravenous administration of cannabinoid receptor (CB) agonist HU-210 (0.05 mg/kg), increases cardiac resistance against arrhythmogenic effect of epinephrine, aconitine, coronary artery occlusion and reperfusion in rats. Pretreatment with CB2-receptor antagonist, SR144528 (1

Nonopioid stress-induced analgesia is the consequence of activation of CB1 receptors by the increased level of 2-arachidonoyl glycerol, anandamide in the periaqueductal gray matter in the midbrain. The activation of cannabinoid CB1 receptors inhibits stress-induced ulcerogenesis due to the

OBJECTIVE To inform research on the etiology and prevention of substance use among rural African American youth by (a) identifying developmental trajectory classes of cannabis use and heavy drinking across adolescence and young adulthood and (b) examining associations between trajectory class

The chemotactic response of Pseudomonas fluorescens was significantly enhanced by the stimulants dl-amphetamine and epinephrine. Acetylcholine, a physiological antagonist of epinephrine, and the cannabinoid tetrahydrocannabinol inhibited bacterial chemotaxis. It may be possible to use bacterial
