The diffusion coefficient and permeability, together with the oxygen uptake rate, have been measured in slices of respiring tissue. Values of these quantities are given for mouse kidney cortex and for implanted tumours of Lewis lung carcinoma in the mouse, and the fibrosarcoma SSB1a in the rat. The diffusion coefficient at 22 degrees C is 1.3 . 10(-5) . cm2 . s(-1) in the kidney, and has the higher value of 1.6 . 10(-5) . cm2 . s(-1) in both tumours. The solubility in all three tissues is similar to that in saline.
已经在呼吸组织切片中测量了扩散系数、渗透率以及氧摄取率。给出了这些量在小鼠肾皮质、小鼠体内植入的Lewis肺癌肿瘤以及大鼠体内的纤维肉瘤SSB1a中的值。22摄氏度时，肾中的扩散系数为1.3×10⁻⁵ cm²·s⁻¹，而在两种肿瘤中的扩散系数更高，为1.6×10⁻⁵ cm²·s⁻¹。在所有这三种组织中的溶解度与在盐水中的溶解度相似。
