Cytoprotection is defined as an ability of pharmacologic agents, originally PGs, to prevent gastric and intestinal mucosal injury produced by a variety of ulcerogenic agents (eg, aspirin, indomethacin, bile acids) and by necrotizing agents (eg, boiling water, absolute alcohol, 0.6 mol/L HCl, 0.2 mol/L NaOH).
Definition of systematic error. : an error that is not determined by chance but is introduced by an inaccuracy (as of observation or measurement) inherent in the system.
systemic error. Error that affects all items comprising a group (such as a production batch) in a similar manner and to a similar magnitude. Systemic errors are caused by a flaw in the system (such as in the calibration of a measuring device), occur in the same direction and, therefore, do not cancel each other out. Also called constant error or systematic error.
