[Lipid peroxidation of the bile in patients with calculous and acalculous cholecystitis].

With a new technique for the assessment of lipid peroxidation products in chloroform bile extracts it was possible to register an increase in the ratio malonic dialdehyde/phospholipids in patients with both calculous and acalculous cholecystitis. Bile of all patients with acute cholecystitis was characterized by a decrease in concentration of all the components, but use of relative parameters (malonic dialdehyde/phospholipids, index of bilirubin fractions and cholesterol/lecithin index) allows to verify the stage of the inflammation. The changes were unidirectional in B-bile and C-bile portions in all the patients with acalculous cholecystitis.

["Fenaf"--a new histochemical stain].

The authors have synthesized a new dye which by its histochemical properties is analogous to the imported aldehyde-fuchsin but much cheaper. The production of this dye under the trade name "Fenaf" is organized at Shostka's factory of chemicals. The dye reveals neurosecretion, thyrothrophocytes of the adenohypophysis, tissue mast cells and other structures that are stained with aldehyde-fuchsin.
