Facilitated Transport of Oxygen Through Hemoglobin Solutions
In a previous study on the facilitated diffusion of oxygen by hemoglobin, we developed a new method using an image-input and -processing system composed of a 3-tube video camera and a digital image analyzer. With this system, diffusion of oxygen in hemoglobin solutions was observed through a microscope, i.e., a deoxyhemoglobin solution was put in a glass capillary tube, and the change in hemoglobin color as oxygen diffused from the open end of the tube was observed and analyzed quantitatively by using our computer algorithm to estimate the oxygen saturation of hemoglobin. Thus, we were able to identify the diffusion profile as resolvable into intervals of 5.5 µm for position and 2.9 sec for time. The experimental results provided new information about the oxygen transport (Hashimoto, et al., 1988).
