[Changes in selenium status, antioxidant enzyme activity and lipid peroxide level after drinking cures in Bad Hall health resort].
61 spa patients, predominantly with heart and vascular diseases, were divided into 2 therapeutic groups. In addition to the usual balneotherapeutic program, one group (J) received a course of "iodine brine concentrate" for drinking (2 x 100 ml, daily iodine uptake approximately 9 mg), and the control group (CI) received isotonic NaCl in the same way. The patients were mostly on a reduced-fat and -calorie diet. The following parameters were determined at the beginning and at the end of the 26-day treatment period: total cholesterol, HDL-cholesterol, triglycerides, lipoprotein (a) (in serum); selenium (Se), malondialdehyde (MDA), and activities of Se-dependent, Se-independent, and total glutathione peroxidase (GSH-PX) (in plasma). In the J group, a significant increase was found in Se-independent (+17%) and total GSH-PX (+5%) and a significant decrease in total cholesterol (-6.9%) and MDA (-13.2%). At the end of the cure, Se levels were higher in the J group than in the C1 group. The only significant change in the C1 group was a decrease in HDL-cholesterol. Positive correlations were found between selenium and Se-dependent GSH-PX (r = 0.253) and between total GSH-PX and Se-dependent GSH-PX (r = 0.665). A negative correlation was obtained between Se-dependent and Se-independent GSH-PX (r = -0.331). The results are discussed with regard to the importance of antioxidant defense mechanisms in several degenerative diseases (atherosclerosis, diabetes, cataract etc.), and also respecting interactions between iodine and selenium metabolism, as well as normalization effects conditioned by the balneotherapy itself.(ABSTRACT TRUNCATED AT 250 WORDS)
