RESUMEN
This experimental study aimed to determine the effects of the combined application of regular exercises and massage on the values of Malondialdehyde (MDA), Nitric Oxide (NOx), Glutathione (GSH), Adenosine Deaminase (ADA) and Superoxide Dismutase (SOD). Twenty five sedentary women (32–50 years) who did not have the habit of getting regularly massages or exercising and participated voluntarily in the study. The subjects were randomly separated into three groups: control group (CG, n=9), exercise group (EG, n=8), and massage and exercise group (MEG, n=8). The basic result of this study was that a statistically significant decrease was observed in the post-test MDA values of both EG and MEG subjects. Moreover, when the GSH and SOD values are compared to CG, a statistically significant increase was determined in the values of both EG and MEG. As a result, the findings show that regular physical activities and massage manipulations significantly decrease MDA, increase SOD and GSH activities, and result in no change in NOx and ADA activities supports the assumption that regular physical activity has positive health effects.
RESUMEN
BACKGROUND: Dust-mites are present in our homes, feed on dead exfoliated skin and other organic material. It is also known that oxidative stress may lead to cellular damage that can be confirmed by markers of cellular disruption. Oxidative stress in various infective processes has been documented. We investigated whether house dust-mites cause oxidative stress in patients. METHODS: Products of lipid peroxidation in erythrocytes and lymphocytes were assessed by measuring malondialdehyde concentration. RESULTS: Our results showed that patients who had a positive skin test for dust-mite antigens and had dust-mites present in their houses (dust-mite positive) had increased erythrocyte malondialdehyde levels (62.39 [18.56] nmol/g-Hb) compared with those who were skin test positive, dust-mite negative (45.45 [10.82]) or skin test negative, dust-mite negative (42.20 [5.68]). They also had significantly higher levels of lymphocyte malondialdehyde (4.22 [0.55] nmol/g-protein) compared with those who were skin test positive, dust-mite negative (3.46 [0.29]) or skin test negative, dust-mite negative (1.25 [0.31]; p <0.05). However, there was no statistically significant difference between the malondialdehyde levels of dust-mite negative/skin test positive and dust-mite negative/skin test negative patients. CONCLUSION: Increased malondialdehyde activity in lymphocytes and erythrocytes in the dust-mite positive/skin test positive group shows the presence of the oxidative stress in patients with dust-mite infestation.
