Structure/nerve membrane effect relationships of some local anaesthetics.
Data on electron structure and octanol-water partition coefficients of certain local anaesthetics are compared with the capacity of reversibly block the action potential of the frog sciatic nerve. Some active parts in the molecules of these substances have been shown to be primarily involved in the action of local anaesthetics.
متن کاملDifferential nerve blocking activity of amino-ester local anaesthetics.
The in vitro sensitivities to local anaesthetic blockade of A, B and C nerve fibres in rabbit vagus nerves were examined using a series of structurally similar amino-ester agents which varied in lipid solubility and anaesthetic potency. A fibres were found to be the most sensitive and C fibres the least sensitive to conduction blockade with all the agents, provided that equilibrium blockade was...
متن کاملA comparative study of the effects of local anaesthetics on platelet aggregation.
A variety of drugs that are generally thought to modify biological membrane action may affect platelet function [ 11. Phospholipase A? is a membrane-bound enzyme, and plays a key role in the release of arachidonic acid from platelet membrane phospholipids [ 21. The arachidonic acid thus released is converted by platelet cyclo-oxygenase and lipoxygenase pathways to prostaglandin endoperoxides, t...

هدف از این تحقیق بررسی برخی عوامل ادراکی واحساسی یعنی استفاده از شیوه های یادگیری زبان ، انگیزه ها ونگرش نسبت به زبان انگلیسی در رابطه با زمینه زبانی زبان آموزان می باشد. هدف بررسی این نکته بود که آیا اختلافی چشمگیر میان زبان آموزان دو زبانه و تک زبانه در میزان استفاده از شیوه های یادگیری زبان ، انگیزه ها نگرش و سطح مهارت زبانی وجود دارد. همچنین سعی شد تا بهترین و موثرترین عوامل پیش بینی کننده ...
15 صفحه اولEfficacy of ultrasound-guided axillary brachial plexus block: a comparative study with nerve stimulator-guided method.
BACKGROUND The aim of this study was to compare the efficacy of axillary brachial plexus block using an ultrasound-guided method with the nerve stimulator-guided method. We also compared the efficacy of ultrasound-guided single-injection with those of double-injection for the quality of the block. METHODS Ninety patients scheduled for surgery of the forearm or hand were randomly allocated int...
