Oxidative stress in coronary artery bypass surgery.

Objective: The aim of this prospective study was to assess the dynamics of oxidative stress during coronary artery bypass surgery with cardiopulmonary bypass.

Methods: Sixteen patients undergoing coronary artery bypass grafting were enrolled. Blood samples were collected from the systemic circulation during anesthesia induction (radial artery--A1), the systemic venous return (B1 and B2) four minutes after removal of the aortic cross-clamping, of the coronary sinus (CS1 and CS2) four minutes after removal of the aortic cross-clamping and the systemic circulation four minutes after completion of cardiopulmonary bypass (radial artery--A2).

Evaluation of oxidative stress in mice subjected to aerobic exercise.

Purpose: To evaluate the influence of aerobic exercise on oxidative stress in mice.

Methods: The study included twenty female mice Mus musculus-Swiss divided into two groups: sedentary control (GA) and exercise (GB), each containing ten animals. All animals underwent an adaptation period of seven days isolated in individual boxes.
