“…The main external (macroenvironment) and inner (microenvironment) factors of biological fluid crystal formation, determining specific features of the tesigraphic facies, were distinguished and classified. The informative value of differential analysis of biomaterial properties by means of modulating the environmental conditions is established.Crystallographic methods of investigation attract much attention of biologists and medics [1,2,4,5,[7][8][9][10]. The diagnostic role of crystallography in medicine was established [1,7-9], but many other aspects of the biocrystallization phenomenon (indicator and prognostic significance, monitoring of body status, etc.)…”
