alkaline incompatibilities
a basic chemical fact that acids and alkalis react together so that the mixing of them in medications is likely to render the medicine ineffective. The phenomenon is utilized in the treatment of poisoning when the objective is to combat the effects of an ingested substance.
alkaline phosphatase
a nonspecific enzyme localized on cell membranes that hydrolyzes phosphate esters liberating inorganic phosphate and has an optimal pH of about 9.5. Serum alkaline phosphatase activity is elevated in hepatobiliary disease, especially in obstructive jaundice, and in bone diseases with increased osteoblastic activity such as hyperparathyroidism, osteitis deformans and bone cancer. The liver and bone tissue each produce a distinct isoenzyme. Called also AP, alkaline phosphomonoesterase, glycerophosphatase.
alkaline picrate test
a technique for estimating urine creatinine levels.
alkaline tide
see postprandial alkaline tide.
alkaline urine
the urine of carnivores is acidic, that of herbivores is alkaline. The presence of an alkaline urine in a carnivore, provided the sample is fresh and uncontaminated, is an indication that the patient is alkalotic, but urine findings must always be interpreted with caution.
