[Endoscopic treatment methods in patients with the postcholecystectomy syndrome].

458 patients with postcholecystectomy syndrome have been examined. In 289 (63.1%) of them the reason of complication and location of the lesion in biliopancreatic-duodenal zone have been specified.

[Characteristics of the distribution in a 2-phase polymer system of L cells at different stages of culture growth].

By the method of counter-current distribution in two-phase polymer system Dextran-500/poly (ethylene)glycol-6000, surface properties of monolayer and suspension sublines of L cells were investigated in relation to the stage of culture growth. The cultivation conditions of both the cell types were identical. It has been shown that with the growth of cell population, the number of cells with lower partition coefficient increases in both the sublines, mostly in cells of monolayer subline.
