[Changes in human biliary vesicle sizes in pathological states].

Changes in the sizes of aggregates of bile vesicles at various nucleation factors were studied by the method of dynamic spectroscopy. It was found that the sizes of bile vesicles in chronic cholecystitis vary from 90 to 200 nm. It was shown that the presence of a large fraction of bile vesicles characterized by a higher cholesterol concentration can serve as a criterion of acuteness of cholecystitis and the intensity of lithogenesis.
