Newborn rats raised on a commercially available iodine-deficient diet developed severe muscle weakness, affecting predominantly their proximal hind limbs, that electrophysiologically and morphologically was determined to be myopathic in type. Follow-up dietary studies, utilizing different
Rats fed a protein-deficient synthetic diet developed hind limb weakness caused by a myopathy with myotonic features on electromyography. Deficiency of vitamin E and selenium, known causes of nutritional myopathy, were excluded. Methionine supplementation of the diet reversed the clinical signs of
This report describes a four-day-old, full-term Connemara colt, presented for the evaluation of a progressive inability to rise unassisted. A diagnosis of nutritional muscular dystrophy was made based on muscular weakness, elevated muscle enzymes and low vitamin E, selenium and glutathione
BACKGROUND
White muscle disease (WMD) is a nutritional myopathy caused by selenium (Se) deficiency. In most soils, Se is present in low concentrations, sometimes even below 0.2 mg/kg, a trend which is seen in many countries. Apart from total soil Se concentrations, soil conditions may be such that
White muscle disease (nutritional myodegeneration) of foals is a peracute to subacute myodegenerative disease affecting skeletal and cardiac muscle. It is caused by a dietary deficiency of selenium and vitamin E, usually in association with predisposing factors such as a high intake of dietary
Four brown pelicans (Pelecanus occidentalis) housed at a rehabilitation facility were found dead after a 3-day history of muscle weakness and after being fed for about 2 weeks from a recent shipment of fish. The birds had pale streaking of the skeletal and heart muscles. Microscopically, the
Selenium and vitamin E deficiencies were studied as part of an evaluation of oxidant defenses in guinea pigs. Male guinea pigs (100-120 g) were fed a control diet (C) or the diet without selenium (0 Se), without vitamin E (0 E), or without either selenium or vitamin E (0 Se-0 E). Between d 30 and
A degenerative skeletal muscle disease with vascular, neurologic, and renal lesions and a probable familial distribution was identified in 4-20-month-old purebred Gelbvieh cattle. Thirteen affected animals were confirmed from 6 separate beef herds, with a mortality rate of 100%. Clinical signs in
A time lag factor of about five days has been identified in an increased incidence of SIDS in relation to a cold day. Sudden exposure to chilling appeared to trigger skeletal muscle weakness and renal failure about five days later in a man found to have only 25% of normal carnitine palmitoyl
Previous studies have shown that selenium (Se) deficiency is associated with nutritional myopathy, known as white muscle disease (WMD), in horses. However, correlations between Se deficiency and clinical findings, such as hematologic biochemical values and pathological features, have not been
