Abnormalities of the skeletal and urogenital system are discussed which result from an interference with the metabolism of calcium in cadmium workers.

... Verapamil and nifedipine will, on the other hand, accomplish similar effects: reducing vascular and golmerular abnormalities by minimizing calcium ...

Studies on dogs intoxicated with methylguanidine present two metabolic abnormalities found in uremic patients, impaired calcium absorption and high plasma triglycerides. Carbohydrate intolerance, another metabolic defect in uremic patients, has also been ...

In previous studies vitamin D has been used to induce cardiac calcium overload in laboratory animals. Interrelationships between calcium and magnesium metabolism are also documented. The authors have investigated the effect of varying vitamin D in the diet on calcium and magnesium levels in plasma, kidney and heart ...

Metastatic pulmonary calcification refers to calcium deposition in the normal pulmonary parenchyma and this deposition is secondary to abnormal calcium metabolism. The most common radiologic manifestation consists of poorly-defined nodular opacities that are mainly seen in the upper lung zone. We present here a ...

Advances in analysis of chemistry and physiology of parathyroid hormone, calcitonin, and Vitamin D are described along with development of techniques in radioassay methods. Emphasis is placed on assessment of normal and abnormal patterns of secretion of t...

We report a case of metastatic pulmonary calcification that showed hyperintense signal on T1-weighted MRI. This uncommon MR appearance of calcification is similar to the MR characteristics of calcification in the brain due to abnormal calcium metabolism. 11 refs., 5 figs.

Calcinosis cutis is characterized by the deposition of insoluble calcium salts in the skin and subcutaneous tissue. The syndrome is separated into five subtypes: dystrophic calcification, metastatic calcification, idiopathic calcification, iatrogenic calcification, and calciphylaxis. Dystrophic calcification appears as a result of local tissue damage with normal ...

Long-term anticonvulsant drug therapy may lead to abnormalities of calcium metabolism resulting in osteomalacia. The prevalence and severity of altered calcium metabolism was studied in an adult outpatient population of persons with epilepsy receiving anticonvulsant therapy for a minimum of 2 ...

Patients with urolithiasis have been increasing in the world, especially morbidity of calcium nephrolithiasis has been increasing in the advanced countries. The changes in the environmental factors including alternation of diet are said to be associated with the increment of morbidity of kidney stone. Idiopathic hypercalciuria is one of the most important risk factor of ...

SUMMARYAge-related neurodegenerative diseases are associated with mild impairment of oxidative metabolism and accumulation of abnormal proteins. Within the cell, the mitochondria appears to be a dominant site for initiation and propagation of disease processes. Shifts in metabolism in response to mild metabolic ...

Calcium transport and calcium signalling mechanisms in bone cells have, in many cases, been discovered by study of diseases with disordered bone metabolism. Calcium matrix deposition is driven primarily by phosphate production, and disorders in bone deposition include abnormalities in membrane ...

Abnormalities of calcium, phosphorus and magnesium homeostasis are common, and collectively are called disorders of mineral metabolism. Normal homeostatic regulation maintains serum levels, intracellular levels, and optimal mineral content in bone. This regulation occurs at three major target organs, the intestine, kidney and bone, ...
