Essential and Toxic Element e-bog

Trace Elements in Human Health and Disease, Volume II: Essential and Toxic Elements is a collection of papers presented at an international symposium on trace elements held in Detroit, Michigan on July 10-12, 1974. The symposium provided a forum for discussing the role of essential and toxic elements such as magnesium and chromium in human health and disease. Comprised of 21 chapters, this volume begins with an overview of magnesium deficiency and magnesium toxicity in humans, followed by an analysis of magnesium deficiency and its relation to calcium, parathyroid hormone, and bone metabolism. The reader is then introduced to the biochemistry and physiology of magnesium, along with chromium metabolism and its biochemical effects on humans. Subsequent chapters deal with the metabolism and biochemistry of selenium and sulfur; the health and disease implications of selenium and glutathione peroxidase; effect of pre-eruptive or post-eruptive fluoride administration on caries susceptibility in the rat; and perinatal effects of trace element deficiencies. The book also considers the basis of recommended dietary allowances for trace elements before concluding with a description of quantitative measures of the toxicity of mercury in humans. This book will be useful to physicians, researchers, nutritionists, and toxicologists.
