In vitro methodology for resistance arteries.
Two commonly used methods for examining the physiological and pharmacological properties of isolated resistance arteries are the ring-mounted preparation and the cannulated, pressurized vessel. Each technique is discussed and consideration given to limitations and advantages. Also presented are examples of comparative differences between them, and practical experimental schemes for calibrating cannulae and for perfusing resistance arteries. Although both methods are valuable, the cannulated approach may better reflect the in vivo properties of the arteries.
