Clinical significance of amylase

Clinical significance of amylase

Amylase is the general name of enzymes that hydrolyze starch and glycogen. It usually catalyzes the hydrolysis of starch slurry on fabrics by amylase. Due to the high efficiency and specificity of amylase, the desizing rate of enzyme desizing is high and the desizing is fast. Less pollution, the product is softer than the acid method and alkali method, and does not damage the fiber. There are many types of amylase. Depending on the fabric, the equipment combination is different, and the process flow is also different. The currently used desizing methods include dipping, stacking, jig dyeing, continuous washing, etc. Due to the small mechanical effect of amylase desizing, The water consumption is small, and the desizing effect can be achieved under low temperature conditions, and it has distinctive environmental protection characteristics.

Increase

Seen in pancreatic duct obstruction, pancreatic abscess, pancreatic injury, intestinal obstruction, gastric ulcer perforation, mumps, peritonitis, biliary tract disease, acute appendicitis, cholecystitis, peptic ulcer perforation, renal failure, or renal insufficiency caused by pancreatic tumors , Salpingitis, traumatic shock, after major surgery, pneumonia, lung cancer, acute alcoholism, after morphine injection, as well as oral contraceptives, sulfa, thiazide diuretics, opioids (codeine, morphine). Narcotic analgesics, etc.
reduce
Seen in liver cirrhosis, hepatitis, liver cancer, acute or chronic cholecystitis, etc.

Pancreatic amylase is excreted from the pancreas into the digestive tract in an active state. It is the most important enzyme that hydrolyzes carbohydrates. Like the amylase secreted by the salivary glands, it belongs to α-amylase. It acts on α-1, 4 glycosidic bonds and has a strong effect on branches. The α-1,6 glycosidic bond of serotonin has no effect, so it is also called endoamylase. Its optimal pH is 6.9. It can be filtered through the glomerulus. It is the only plasma enzyme that can appear in the urine under normal conditions.
