Diffusivity of various inert gases in rat skeletal muscle



Diffusivity of various inert gases in rat skeletal muscle



Pfluegers Archiv European Journal of Physiology 359(3): 219-230



Krogh's diffusion constant (K) was determined for various inert gases in isolated rat abdominal muscle at 37.degree. C by measuring the amount of gas diffusing per unit time and partial pressure difference through a portion of the muscle of known surface area and thickness. The following mean values for K, in 10-9 mmol.cntdot.min-1.cntdot.cm-1.cntdot.torr-1, were obtained: acetylene, 41.2; nitrous oxide, 20.0; chlorodiffuoro-methane, 18.8; H2, 1.67; methane, 1.27; sulfur hexafluoride, 0.081; and He, 1.42. From K, the diffusion coefficient, (D) was calculated using the solubility coefficient determined previously in the same preparation. The D values were about 1/2 the D values in water at 37.degree. C. Model calculations show that for gases with high lipid/water partition coefficient, D in tissues containing lipid is underestimated by this method. Graham's law (inverse proportionality between D and square root of molecular mass) represented a useful approximation for these gases. A better correlation was obtained between D and the molecular diameter.
