The pharmacology of beta-adrenergic blocking agents.
T HE endogenously released neurotransmitter substance, norepinephrine, or an injected sympathomimetic amine, ultimately exerts its actions on an organ system by combining with an area of the effector cell termed the adrenergic “receptor site.” That drugs and neural chemical mediators react with specific receptors in living tissues was suggested by Langley”” in 1905, who suggested that effector ...
متن کاملFemoral vascular effects of some beta receptor adrenergic blocking agents.
Beta receptor adrenergic blocking agents produce a fall of systemic arterial blood pressure which has been attributed to interference with the function of sympathetic nerves to the heart (1). While pronethalol and propranolol are known to have a peripheral vasodilator component of action which contributes to their hypo tensive effect (2, 3), it has not been determined if the more recently synth...
متن کاملBeta-adrenergic blocking agents in heart failure.
Cardiac dysfunction in heart failure is widely recognized as a progressive process, regardless of the clinical signs and symptoms. An increase in cardiac sympathetic drive is one of the earliest neurohormonal responses occurring in patients with heart failure and may be one of the major causes of the progressive remodeling leading to the decline in myocardial function, and responsible for the p...
متن کاملthe effects of changing roughness on the flow structure in the bends
flow in natural river bends is a complex and turbulent phenomenon which affects the scour and sedimentations and causes an irregular bed topography on the bed. for the reason, the flow hydralics and the parameters which affect the flow to be studied and understand. in this study the effect of bed and wall roughness using the software fluent discussed in a sharp 90-degree flume bend with 40.3cm ...
The effects of Adrenergic agents on the dopaminergic-induced sniffing
There is evidence indicating that adrenoceptor mechanisms may influence some of the behaviors in rat. However the role of adrenoceptor agents on sniffing has not been identified. In the present study, the influence of adrenoceptor agents on sniffing induced by apomorphine and amphetamine has been investigated. Male Albino rats, weighing 150-250 g were used for all experiments. The behavior wa...
