The sodium intake of preschool children in their home environment was investigated and the major sources of sodium other than added table salt identified. Thirty five children from a Southampton general practice were studied. Twenty four hour urinary sodium excretion was measured as a reliable indicator of daily total sodium intake. The daily intake of sodium other than that from added table sa...

Amajor difficulty in determining the mechanisms responsible for human hypertension is the great variety of systems involved in regulating blood pressure and our tendency to assume that these mechanisms are similar in all hypertensive patients. Even when patients are separated into those whose blood pressure is or is not sensitive to the level of sodium intake, it is often assumed that all "salt...

THIS paper is an analysis of an unusual outbreak of cholera in a confined community of 7,000 more or less disabled British and Dutch prisoners of war. By the middle of May, 1943, disquieting rumours reached us of outbreaks of cholera among railroad construction parties in Central Thailand. All these rumours agreed on two things: the outbreak was severe and facilities for treating the cases were...

To ascertain current approaches of physicians to nutritional-hygienic management of hypertensive patients and their children, a survey was done among a random sample of Chicago-area generalists, internists, and cardiologists. Thirteen items related to advice for patients; two for their children. Of 713 physicians holding M.D. degrees in the sample, 573 (80%) responded. For hypertensive patients...

Shallow high resolution 2-D and 3-D seismic reflection techniques are assisting in the subsurface delineation of a surface collapsc feature (sinkhole) at Weeks Island. Louisiana. Seismic reflection surveys were conducted in March 1994. Data from walkaway noise tests were used to assist selection of field recording parameters. The top of the salt dome is about 180 ft below ground surface at the ...

OBJECTIVE The purpose of this study was to evaluate caries and dental fluorosis among Mexican preschoolers and school-aged children in a non-endemic zone for fluorosis and to measure its biological indicators. METHODS DMFT, DMFS, dmft, dmfs, and CDI indexes were applied. Fluoride urinary excretion and fluoride concentrations in home water, table salt, bottled water, bottled drinks, and toothp...

Table olives have an enormous importance in the diet and culture of many Mediterranean countries. Albeit there are different ways to produce this fermented vegetable, brining/salting, fermentation, and acidification are common practices for all of them. Preservation methods such as pasteurization or sterilization are frequently used to guarantee the stability and safety of fermented olives. How...

12.091 Medical Geology/Geochemistry: Element Report IAP 2006, 01/30/2006 Christopher Love Introduction If you have ever looked carefully at your commercial container of salt sitting in the cupboard, then you have noticed that it is iodized. Have you ever wondered what that means, or why it is mentioned? The simple answer to these questions is that a form of the element, iodine, is added to the ...

Iodine is a particularly relevant element in thyroid gland physiology. Although healthy follicular cells have several mechanisms which allow them to adapt to marked changes in iodine provision, both iodine deficiency and excess may cause dysfunction in a diseased thyroid gland. A 26-year-old female patient with an unremarkable history attended her family physician reporting fatigue for several ...

philes Pseudomonas indigofera (Shiio et al., 1965) and Chlorella pyrenoidosa (John 8c Syrett, 1967) is apparently similar. In mutant PC2 NG35 cells the lyase accounts for 16 % of the soluble proteins. The corresponding proportion of malate synthase is 2.5% in the wild-type and 6% in the mutant. Themolecularweightsof thenativeenzymes, determined by gelfiltrationonaSepharose 6B column, are given ...
