[The dynamic functional-morphological changes in the small intestine of obese patients undergoing weight-reducing diet therapy].

Two groups of pathogenetic mucosal changes peculiar to fasting period were revealed in 28 obese patients: a structural rearrangement of mucosa with inhibition of mitotic activity of epithelial crypts, and the inflammatory responses manifested by increased cellular infiltration of stroma and compensatory-adaptive changes of capillary bed structures. The adequate dietotherapy provided full recovery of the mucosa tissue parameters on the 26th day.

[Methodologic procedures in the study of the biliary system using cholecystography].

New methods of x-ray investigation of the biliary system (BS) were proposed. A method of hydrostatic load in per os cholecystography, a method of the combined use of per os and iv cholecysto-cholangiography with hydrostatic load, and the use of finely divided suspension are simple and reliable, permitting one to obtain objective information on the BS.
