Objective : To study and compare the citraturia of subjects with uric acid and oxalic acid stones with the citraturia of subjects with calcium-oxalic stones. Material and methods : Twenty-four hour urinary citrate were studied by subjects with uric acid and oxalic acid stones and by subjects with oxalo-calcic stones. Results : Twenty-four-hour urinary citrate assays performed in 20 subjects with uric acid and oxalic acid renal stones revealed a mean citraturia of 190.9 mg (1,...   [Suite...]

Natural mineral waters of Salies-de-Béarn (Pyrénées-Atlantiques - 64) are cold waters characterized by strong chlorinated and sodic properties. They are used in thermal treatments in the field of rheumatology, gynaecology and paediatrics. The rise of the temperature of these mineral waters, submitted to precise experimental conditions, allows to obtain thermal derived such salt and water mother*[1]. Those derived products have interesting therapeutic properties in terms of t...   [Suite...]

Evaluation of disinfection techniques used in thermal spa establishments via a mineral water pilot system. The physical and chemical properties of natural mineral water are at the origin of its importance to health. According to French law, mineral water must have the same chemical composition and the same purity from the source to the point of use. Hence, no residual disinfectant can be used to treat a natural mineral water, and good maintenance is crucial in limiting micro...   [Suite...]

Comparative study of bromine and chlorine in Dax’ thermal water disinfection. The use of alternative products instead of chlorine derived products in order to decontaminate thermal swimming pools, is a capital issue to optimize the sanitary situation in thermal centers. 25 litres of natural mineral water from the thermal city of Dax (France, 40100) were used for the realization of this experimental study, which aims to prove the efficiency of bromine, as a real alternative ...   [Suite...]

Protocol for thermal substrates analysis, thermal mud and sediments. The sanitary state of thermal mud quality in establishments needs a particular attention. Exposed to a large public, thermal stations must assured the microbiological quality of thermal susbtrats and the maintenance of this quality. The development of this protocol is to propose standardized conditions to realise microbiological analyses being able to be led by the laboratories of self-monitoring, on therma...   [Suite...]

The extremophilic micro-organisms Numerous research teams in the world are studying extremophilic micro-organisms, some of them, living at high salt concentrations (halophiles), at cold or hot temperatures (psychrophiles or thermophiles), at low or high pH (acidophiles or alcaliphiles) or under pressure (piezophiles). These unconventional conditions for life suggest that such microbes use original strategies (specific enzymes) to adapt to physico-chemical constraints that th...   [Suite...]

Spa therapy in the national public finances in France. A macro-economic approach. Spa therapy in France generates activity which participates in national economy by resources as well as by expenses. The contribution of spa therapy to the national wealth may be considered as the Raw Internal Production of this activity. The intervention of social and fiscal organisations in payment of balneological treatments may be considered as the Social and Fiscal Costs of the activity. ...   [Suite...]
