Spa Therapy and Oxidant Antioxidant Systems / Prof Dr Nergis ERDOGAN ISTANBUL 3 ROS play a major role in events like Inflammatory reactions Cataract, arteriosclerosis Intracellular aging, Cell necrosis and apoptosis, Ischemia reperfusion injury Cancer Introduction

Spa Therapy and Oxidant Antioxidant Systems / Prof Dr Nergis ERDOGAN ISTANBUL 4 ROS promoters Physical and psychological stress, High caloric diet, Alcohol and cigarette use Air pollution, ozone UV light, microwave Ionizing radiation Some chemotherapeutic Hyperthermia treatment also increase ROS production Introduction

Spa Therapy and Oxidant Antioxidant Systems / Prof Dr Nergis ERDOGAN ISTANBUL 5 Aerobe organisms have antioxidant defence systems Intracellular antioxidant enzyme systems –Super oxide dysmutase (SOD) catalases, glutathione peroxides –In vivo synthesizing substances: Bilirubins, sex hormones, melatonine, lipoic acide, coenzyme Q, and uric acid –Ceruloplasmin, albumin, transferrin, haptoglobin, lactoferrin and hemopexin Introduction

Spa Therapy and Oxidant Antioxidant Systems / Prof Dr Nergis ERDOGAN ISTANBUL 6 A, C and E vitamins and Plant phenols have antioxidant features Oxidative stress may results with adaptation or cell damage Cells response to mild oxidative stress by antioxidant defence systems Introduction

Spa Therapy and Oxidant Antioxidant Systems / Prof Dr Nergis ERDOGAN ISTANBUL 7 Oxidative stress Damage DNA and other molecules and cause degenerative diseases, malignity and aging Therapy with hyper thermal baths, drinking cures and peloid packs reduce oxidative stress and induce antioxidant defence Introduction

Spa Therapy and Oxidant Antioxidant Systems / Prof Dr Nergis ERDOGAN ISTANBUL 20 DISCUSSION and CONCLUSION

Spa Therapy and Oxidant Antioxidant Systems / Prof Dr Nergis ERDOGAN ISTANBUL 21 Spa therapy decreases oxidant stress ?! Increases TAA levels in male and Decreases in females (menopause-estrogens deficiency?) Decrease in oxidant stress is more prominent Increase of antioxidant defence is less manifest DISCUSSION and CONCLUSION

Spa Therapy and Oxidant Antioxidant Systems / Prof Dr Nergis ERDOGAN ISTANBUL 22 Oxidant effect of hyperthermic baths and antioxidant consumption in defence to oxidative stress Disappearance of inverse proportion between disease duration and MDA level Balneotherapy more effective in early period of disease in decreasing oxidative stress??! DISCUSSION and CONCLUSION
