Operation of the Isolated Organ Bath and Kymograph (Manual and Digital)

1. Introduction The isolated organ bath preparation represents a cornerstone technique in experimental pharmacology and physiology. This method involves the maintenance of an excised tissue, typically smooth muscle, in a controlled artificial environment that supports its viability and physiological responsiveness. The apparatus allows for the precise application of pharmacological agents and the quantitative measurement of … Read more

Principles and Composition of Physiological Salt Solutions

1. Introduction Physiological salt solutions represent a cornerstone of experimental pharmacology and physiology, providing an artificial extracellular environment that sustains the viability and functional integrity of isolated tissues and organs. These solutions are carefully formulated aqueous mixtures of inorganic salts, glucose, and sometimes other organic components, designed to mimic the ionic composition, pH, osmotic pressure, … Read more

Calculation of Dose and Concentration of Drug Solutions

Introduction/Overview The accurate calculation of drug doses and the preparation of solutions with precise concentrations represent fundamental competencies in clinical pharmacology. Errors in these calculations can lead to therapeutic failure or, more critically, patient harm through toxicity. Mastery of these principles is therefore not merely an academic exercise but a core component of patient safety. … Read more
