1 Slate can start as low as $1-$3 a square foot for basic floor tiles. 2  Depending on size, finish, thickness and color, higher quality slate tiles can cost $4-$10 a square foot, while mosaics and other specialty tiles (usually used as accents) can be $8-$35 a square foot for just the tiles. Slate sealer costs $10-$30 a gallon. 2  For a shiny or matte finish or if the slate is relatively porous (tending to stain), the slate should be sealed before and after installation, and then every one to two years, depending on the amount of traffic and wear on the floor.
Save. Amylase and lipase are digestive enzymes produced by the pancreas. Amylase and lipase tests are used to distinguish acute appendicitis from acute pancreatitis. Both tests are done on blood, but amylase may also be tested from a urine sample.
As an example, serum amylase and lipase levels may be elevated in patients with renal failure. (See Serum enzymes in patients with renal failure .). â Organs other than the pancreas can produce these enzymes. Alcoholics, for example, may have an elevated serum amylase of salivary origin. The most commonly used amylase assays cannot differentiate between salivary and pancreatic amylase. â Certain serum factors influence amylase and lipase enzyme activity. As an example, patients with pancreatitis due to hypertriglyceridemia may appear to have normal amylase levels, most likely due to a circulating factor that inhibits the enzyme's activity [ 5 ].
