The plasma volume of the Wistar rat in relation to the body weight

Summary The plasma volume of 43 male Wistar rats, weighing between 140 and 350 g, was determined. A close linear relationship between plasma volume and body weight was found: plasma volume (ml)=0.0291×body weight (g)+2.54.Acknowledgment. The excellent assistance of Mr J.S. Bouwer in animal experiments is gratefully acknowledged.
