The cellular basis of neurovascular metabolic coupling.
Functional brain imaging studies, such as positron emission tomography and functional nuclear magnetic resonance imaging, are based on the regional increases in cerebral blood flow, glucose consumption and oxygen consumption that are associated with regional increases in neuronal activity. The cellular basis of the signals that are measured is however incompletely understood at present. An incr...
متن کاملDISEASEOF THE MONTH Metabolic Alkalosis
Generation and Maintenance of Metabolic Alkalosis The pathogenesis of metabolic alkalosis involves both the generation and maintenance of this disorder ( 1 ). The generation of metabolic alkabosis refers to the addition of new HCO to the blood as a result of either loss of acid or gain of alkali. New HCO1 may be generated by either renal or extrarenal mechanisms. Because the kidneys have an eno...
متن کاملApproach to metabolic alkalosis.
Metabolic alkalosis is a common disorder, accounting for half of all acid-base disturbances in hospitalized patients. It is the result of an increase in bicarbonate production, a decrease in bicarbonate excretion, or a loss of hydrogen ions. Most causes of metabolic alkalosis can be divided into 4 categories: chloride depletion alkalosis, mineralocorticoid excess syndromes, apparent mineralocor...
متن کاملMetabolic alkalosis and myoclonus.
This is the first case reported of vomiting-induced metabolic alkalosis associated with myoclonus. The report describes an unusual presentation of myoclonus secondary to acid-base disturbance caused by recreational drug-induced vomiting. The severe derangement of hyponatraemia, hypokalaemia, and alkalosis appears to have been reasonably well tolerated due to the gradual onset and relatively lon...
متن کاملMannitol-induced Metabolic Alkalosis
Mannitol is an osmotic diuretic agent useful in a variety of clinical conditions. This study is based on acid-base and electrolyte changes seen after the intravenous infusion of hypertonic mannitol for the prevention of cerebral edema. The study subjects were divided into 3 groups: for group A, an amount of 300-900 mL 15% mannitol was intravenously infused over the period of 60 to 90 minutes; f...
