Abstract
It is guessed that the behavior of the reactive oxygen species (ROS) in the blood may be affected by the characteristics of the membrane during the hemodialysis in practice. then. an attempt to measure the ROS concentration in the blood at the appointed times during hemodialysis has been done by the spin trapping technique.
In result, the ROS concentration creased remarkably on the cellulose membrane. on the other hand, the con centration slightly changed on the EVAL at the use of the anticoagulant agent and at the no use of the agent
