the effects of chronic metabolic acidosis, alkalosis and alloxan-induced ketoacidosis on g6pd activity of rat kidney, liver and erythrocytes were studied. metabolic acidosis significantly increased the activity of kidney enzyme (55%) but decreased the liver (43%) and erythrocyte (38%) enzyme activities. alkalosis did not make a significant change in the kidney or liver enzyme activity but sligh...

This study examined the effects of extracellular alkalosis on the metabolism and performance of perfused rat hindlimb muscles during electrical stimulation. Three acid-base conditions were used: control (C, normal acid-base state), metabolic alkalosis (MALK, increased bicarbonate concentration), and respiratory alkalosis (RALK, decreased PCO2). A one-pass system was used to perfuse the hindlimb...

BACKGROUND Acid-base imbalance in various metabolic disturbances leads to human brain dysfunction. Compared with acidosis, the patients suffered from alkalosis demonstrate more severe neurological signs that are difficultly corrected. We hypothesize a causative process that the nerve cells in the brain are more vulnerable to alkalosis than acidosis. METHODS The vulnerability of GABAergic neur...

Maintenance of metabolic alkalosis generated by chloride depletion is often attributed to volume contraction. In balance and clearance studies in rats and humans, we showed that chloride repletion in the face of persisting alkali loading, volume contraction, and potassium and sodium depletion completely corrects alkalosis by a renal mechanism. Nephron segment studies strongly suggest the correc...

A method for the assessment and management of factors both causing and maintaining a primary metabolic alkalosis is presented. During a 2-year period 65 patients with metabolic alkalosis were treated with saline and potassium chloride infusions. In four patients the alkalosis was refractory and required additional therapy. An infusion of hydrochloric acid 0.12-0.24 mol/litre through a central v...

Hyperventilation in pregnancy is a cause of chronic respiratory alkalosis. Alkalosis either metabolic or respiratory may cause intracellular shift of potassium ions that may lead to hypokalaemia. However, the resultant hypokalaemia in respiratory alkalosis is usually mild and does not cause much clinical features. A five-months-pregnant female of the age 25 years presented with sudden onset fla...

Hypoproteinemia is a common disturbance in patients suffering from various diseases. It can be accompanied by hypovolemia and hypotension that influences the volume space of drugs in the body as well as the acid-base balance. In the present study, 22 patients with hypoproteinemia (8F, 14M) constituted group A. In this group the acid-base disorders as well as their importance were evaluated. Fro...
