Марганец — очень токсичный металл. Острые отравления чистым марганцем не встречаются. В условиях производства имеют практическое значение хронические интоксикации марганцем. организм марганец проникает через дыхательные пути, меньше желудочно-кишечный тракт и кожу. случае хронического действие марганца на общетоксическое с подавляющим поражением центральной нервной системы (подкорковых структур...

Between January 1978 and December 1979 23 consecutive patients aged under 40 years with acute ischemic brain infarction were admitted to the department of neurology, Meilahti University Hospital in Helsinki. In 10 patients (43%) the onset of symptoms was preceded within 24 hours by ethanol intoxication, and all but one symptom occurred at weekends when most liquor is consumed in Finland. Ethano...

Cardiovascular shock due to verapamil intoxication is often refractory to standard resuscitation methods. Recommended therapy includes prevention of further absorption of the drug, inotropic therapy, calcium gluconate, and hyperinsulinemia/euglycemia therapy. Often further measures are needed such as ventricular pacing or mechanical circulatory support. Still, mortality remains high. Levosimend...

Fulminant hepatic failure is a fatal complication of iron intoxication. Currently, there no well-established treatment. A 23-year-old Japanese woman, with past medical history deficiency anemia, presented fulminant caused by Multiple organ progressed despite plasma exchanges and deferoxamine therapy, she subsequently developed acute respiratory distress syndrome. Even though Venous-Venous Extra...

it is extremely challenging to measure first-order rate coefficients for soil nitrate transformation processes directly, either in the laboratory or in the field. in this study, an improved inverse method was proposed to optimize the first-order rate coefficients by considering the intermediate changing processes of the integrated functions. a numerical experiment was designed to test the accur...

Plants differ in tissue localization of nitrate reduction and assimilation. Some species reduce nitrate primarily in the leaves, whereas other species localize nitrate reduction and assimilation in the roots. We determined how nitrate assimilation is partitioned among leaves, stems and roots of poplar (Populus tremula L. x P. alba L.) by comparing tissue differences in in vivo nitrate reductase...

Hyponatremia is the most common electrolyte disorder that requires careful management. Water intoxication with hyponatremia is rare condition that originated from overhydration. Water intoxication, also known as dilutional hyponatremia, develops only because the intake of water exceeds the kidney's ability to eliminate water. Causes of this water intoxication include psychiatric disorder, force...

OBJECTIVE To determine whether or not risperidone is efficacious in treating self-induced water intoxication in patients with chronic schizophrenia. METHOD We carried out a prospective 11-month open-label study using risperidone to treat 8 men with chronic schizophrenia and self-induced water intoxication. RESULTS The 8 men were not able to reduce their fluid consumption compared with their...
