Sixty patients with a first acute myocardial infarction and no current treatment with cardioactive drugs were included in a prospective study of the relationship between serum potassium concentration and the early occurrence of ventricular tachycardia and premature ventricular contractions (PVCs). Serum potassium level (range 2.5 to 5 mmol/liter) was estimated 3.8 + 2.5 hr (mean + SD) after the...

Reninoma is a rare, renin-secreting, benign renal neoplasm that can cause secondary hypertension. We report a case of a 21-year-old man who suffered from progressively worsening headache for 2 months with a history of hypertension for 7 years. Laboratory studies showed normal potassium level, increased basal plasma renin activity, and normal serum aldosterone level. Abdominal computed tomograph...

background and objectives: the magnetotactic bacterium magnetospirillum gryphiswaldense (msr-1) mineralizes the magnetite (fe3 o4) crystals and organizes a highly ordered intracellular structure, called the magnetosome. iron transport system supports the biogenesis of magnetite. although iron is an essential trace element for many metabolic pathways of the body, increase or decrease in iron wil...

background: obesity is caused by several factors while sedentary lifestyle and excessive energy intake are the most important ones. obesity could be due to abnormal calcium metabolism, and a high calcium intake may prevent obesity. studying serum calcium level, albumin, and triglyceride concentrations, we searched for probable correlation between serum calcium level and anthropometric data of t...

BACKGROUND One of the causes of mortality in acute myocardial infarction (AMI) is ventricular tachycardia. Abnormal serum Potassium (K) level is one of the probable causes of ventricular tachycardia in patients with AMI. This study carried out to determine the relationship between serum potassium level and frequency of ventricular tachycardia in early stages of AMI. METHODS Ina cross-sectiona...

Familial periodic paralysis is a malady usually characterized by (1) recurrent flaccid muscular paralysis, (2) history of the disease in other members of the family, (3) depression of the level of potassium ions in the blood serum during an episode of paresis, (4) impairment of electrical excitability of the musculature, (5) impairment of deep reflexes, (6) retention of consciousness without al...

N Engl J Med 2003;349:875-81. Copyright © 2003 Massachusetts Medical Society. A 20-year-old woman presents with fatigue; laboratory tests reveal a serum potassium level of 2.3 mmol per liter and a serum bicarbonate level of 36 mmol per liter. She is 163 cm (64 in.) tall and weighs 54 kg (119 lb). The findings on physical examination are normal. On questioning, she admits to binge eating and vom...

Introduction: The long time use of opium has some effects on serums biochemical factors, the determination of this variation is a new approach in understanding off addiction and relive of drug abuser health. Hence in this study, these indicators in person who were withdrawing of opium have been studied. Materials and Methods: In this cross-sectional study bloods biochemical factors such as fast...
