Evaluations of Oxidative Stress, Thiol/Disulphide Homeostasis, and Nitric Oxide in Patients with Aneurysmal Subarachnoid Hemorrhage.

Aim: To investigate changes in nitric oxide (NO) levels, oxidative stress, and dynamic thiol/disulphide homeostasis in the serum and cerebrospinal fluid (CSF) of patients with aneurysmal subarachnoid hemorrhages (aSAH).

Material And Methods: This prospective study included a total of 40 consecutive patients suffering from aSAH, who were operated on within the first 48 hours from onset of symptoms; CSF and blood samples were collected from these patients during their operations. To create a control group, blood samples and cerebrospinal fluid were taken from patients (n=40) without neurologic disorders who had undergone lumbar puncture for spinal anesthesia.
