Dyscrasia

Description:

Dyscrasia (from Greek dys — a prefix for designation of high-quality disturbance and kra-sis — mixing), the term which was widely used in former medicine starting with Hippocrates who entered it for designation of constitutional diseases at which it was assumed spoiled in comparison with norm, composition of juice of an organism. At the same time a number of kraz differed. So, one of the last representatives of humoral pathology, Rokitansky, speaks about tubercular, fibrinous, cancer, typhus, sypny, septic, etc. "kraza". With replacement of the humoral direction in pathology cellular, to the concept "kraz", in sense it is endogenous the arising features of an organism, began to oppose ponya-ty about the changes of blood and juice of an exogenous origin created by any infections and intoxications; found in such value possible to use the specified term and Virkhov, the founder of cellular pathology. In a crust, time this term lost the value, but the concept of diathesis which was mixing up in ancient medicine with a concept of a dyscrasia remained and became even very common with development of the modern doctrine about the constitution. In a concept of diathesis however other invests in a crust, time, wider in comparison with former sense.
