Clinical Trial Summary

The aim of this research is to evaluate thiol‑disulfide balance in cervix cancer patients

Description:

To date various oxidative stress parameters were studied in patients with cervix cancer, however dynamic thiol disulfide hemostasis has not been previously investigated.

The thiol-disulfide balance in the circulation will be measured by the automated system created by Erel & Neselioglu (1).

Aforementioned oxidative stress markers will be measured via Cobas c501(Roche Diagnostics, Indianapolis, IN, USA) used with spectrophotometry
• Total Oxidant Capacity(µmolH2O2Equiv/L)
Aforementioned oxidative stress markers will be measured via Cobas c501(Roche Diagnostics, Indianapolis, IN, USA) used with spectrophotometry
• Ischemia Modified Albumin(IU/mL)
The serum Ischemia Modified Albumin concentrations were measured as described by Bar-Or et al. (Bar-Or et al. 2000).
