The pathological increase of oxygen free radical generation has already been recognised in more than one hundred diseases. To gain information about the consequences of oxidative stress the investigation of plasma antioxidants seems to be plausible. In our study we used a new kit (RANDOX, England) for measurement of total antioxidant status (TAS) to determine whether it has diagnostic value in comparison with our earlier results of measuring other parameters of oxidative stress in the following diseases: i./In the group of patients with ischemic heart disease (n = 19) the TAS elevated from 1.08 +/- 0.13 to 1.16 +/- 0.11 mM after 2 weeks of cardioprotective drug administration showing the beneficial effect of drug treatment. ii./In the group of patients with essential hypertension (n = 47) its values were below the normal range (1.11 +/- 0.15 mM) at the time of the first investigation and increased gradually following antihypertensive treatment. iii./The changes of TAS values of patients who underwent open (n = 21) or laparoscopic (n = 21) cholecystectomy indicated the less surgical trauma following laparoscopic procedures. Our results suggest that determination of TAS is a valuable and reproducible method to detect the actual antioxidant status in patients.
