Keywords: Sulphurours water, Hydrogen sulphide, Aging, Medical Hydrology, Thermalism, Balneotherapy, Nervous system functions, Immunity Introduction and Aim Hydrogen sulphide, generated endogenously in mammalian tissues, is a synaptic modulator and neuro protector in the brain increasing the levels of gluthathione, a major cellular antioxidant. The role of hydrogen sulphide in inflammation is controversial and complex showing pre inflammatory and anti inflammatory effects depending on its concentrations and the donor used. Besides that endogenous production of hydrogen sulphide, it is known that thermal waters rich in sulphur are exogenous sources of this molecule, and they have been traditionally used in bath therapies because of their beneficial effects on human health. As the ageing process is a chronic oxidative stress situation with a decrease of gluthathione levels and a nervous and immune systems deterioration, the objetive of the present work was to investigate in old mice the role of baths with sulphurous thermal waters in several nervous and immune functions as well as gluthathione leukocyte levels. Congreso Internacional del Agua – Termalismo y Calidad de Vida. Campus da Auga, Ourense, Spain, 2015 Design and Methods Twenty months old female ICR-CD1 mice were used. They were divided in three groups: the first was submitted a daily bath of 15 minutes in sulphurours water (called "sulphurours water group", SWG), the second in normal water (called "control water group", CWG), and the third was mantained in the cage ("control sedentary group", CSG). The treatments were performed during two weeks, five days per week. Neuromuscular coordination was analyzed through the tightrope test, and the exploratory and anxiety-like behaviours by open field, holeboard and T-maze tests. In addition, peritoneal leukocytes were obtained and macrophage phagocytosis, digestion capacity (intracellular reactive species (ROS) levels), natural killer (NK) activity against tumour cells and total GSH levels, determined. Results The results show that the neuromuscular vigour and exploratory capacities are improved and anxiety reduced in animals of SWG with respect those in CSG, and in some parameters they are better than mice of CWG. The GSH levels were higher in leukocytes from SWG than in the other groups. The phagacytosis was also higher in macrophages from SWG than from CWG and in the animals of this group than those of CSG. The NK activity was higher in leukocytes from SWG and CWG with respect to those of CSG. Conclusions Bath sessions in thermal water rich in sulphur compounds improve several nervous system functions and peritoneal cell activities as well as the redox state of these cells in old mice. Since the immune parameters studied, which show an agerelated deterioration, are markers of biological age and longevity, this improvement suggests that the bath treatment is a good strategy to slow down the ageing process and reach a healthy longevity.

INTRODUCTION AND AIM DESIGN AND METHODS Hydrogen sulphide (H2S), generated endogenously in mammalian tissues, is a synaptic modulator and neuro-protector in the brain increasing the levels of gluthatione (GSH), a major cellular antioxidant. The role of H2S in inflammation is controversial and complex showing proinflammatory or anti-inflammatory effects depending on its concentrations and the donor used. Besides that endogenous production of H2S, it is known that thermal waters rich in sulphur are exogenous sources of this molecule, and they have been traditionally used in bath therapies because of their beneficial effects on human health. As the ageing process is a chronic oxidative stress situation with a decrease of GSH levels and a nervous and immune systems deterioration, the objective of the present work was to investigate in old mice the role of baths with sulphurous thermal waters in several nervous and immune functions as well as GSH leukocyte levels. Twenty months old female ICR-CD1 mice were used. They were divided in three groups: the first was submitted a daily bath of 15 minutes in sulphurous water (called “sulphurous water group”, SWG), the second in normal water (“control water group”, CWG), and the third was maintained in the cage (“control sedentary group”, CSG). The treatments were performed during two weeks, five days per week. Neuromuscular coordination was analyzed through the tightrope test, and the exploratory and anxiety-like behaviours by open field, holeboard and Tmaze tests. In addition, peritoneal leukocytes were obtained and macrophage phagocytosis, digestion capacity (intracellular reactive species (ROS) levels), natural killer (NK) activity against tumour cells and total GSH levels, were determined.

CONCLUSIONS Bath sessions in thermal water rich in sulphur compounds improve several nervous system functions and peritoneal cell activities as well as the redox state of these cells in old mice. Since the immune parameters studied, which show an age-related deterioration, are markers of biological age and longevity, this improvement suggests that the bath treatment is a good strategy to slow down the ageing process and reach a healthy longevity.
