CNS Pharmacology - Pharmacology MCQ ACEM, Top Questions & Answers. Rated A+ Which of the following agents has a pure beta agonist effect in the circulation? 1. Isoprenaline 2. Dopamine 3. Adrenaline 4. Noradrenaline - -1. Isoprenaline Isoprenaline is a pure β-receptor agonist and a potent vasodilator. Dopamine acts on D1 receptors (vasodilation) at higher doses it affects α- and β-receptors. Adrenaline acts on β1, β2 and α1 receptors depending on the dose. Noradrenalin is a ...

Rectification Constant - A value of the heat unit formula that varies depending on the generator used. Generators used in Radiography - single phase generator delivers pulsating x-ray beam (1), Three phase generator = 3 phase 6 pulse machine (1.35) , High frequency generator = 3 phase 12 pulse machine (1.41) Rectification - The rectifier of the x-ray tube changes alternating current (AC) to direct current (DC). This process ensures that the x-ray production flows in the right direction; fr...
