Acute Response to Acid-base Stress

Eating Behavior in Response to Acute Stress.

Obesity is a medical and social problem with a dramatically increasing prevalence. It is important to take action since childhood to prevent and treat obesity and metabolic syndrome. Infantile obesity affects all body systems starting in childhood and continuing to adulthood. Understanding the impact of stressors on weight status may be especially important for preventing obesity. The relations...

Stress and acid-base balance in chickens.

Two trials were conducted to study the effects of continuous infusion of adrenocorticotropic hormone (ACTH) on acid-base balance in broiler chickens. Osmotic pumps delivered 8 IU of ACTH in saline/kg of BW/d for 7 d or the same saline volume as used in ACTH at 1 microL/h for 7 d. Blood samples were taken on d 0 (baseline values) and on d 4, 7, and 14 after onset of the infusions. The ACTH treat...

Acid-base balance in acute gastrointestinal bleeding.

Acid-base balance has been studied in 21 patients with acute upper gastrointestinal bleeding. A low plasma bicarbonate concentration was found in nine patients, accompanied in each case by a base deficit of more than 3 mEq/litre, indicating a metabolic acidosis. Three patients had a low blood pH. Hyperlactataemia appeared to be a major cause of the acidosis. This was not accompanied by a raised...

Acid-base disturbances in acute asthma.

The clinical features, arterial blood gases, and acid-base profile were examined in 229 consecutive episodes of acute asthma in 170 patients who required hospitalization. A simple respiratory alkalosis was the most common acid-base disturbance, occurring in 48 percent of the episodes. Metabolic acidosis, either alone or as part of a mixed disturbance, was noted in 28 percent. Of 60 episodes pre...
