[Duodenogastric reflux in humans].

Human duodenogastric reflux (DGR) was comprehensively studied via measurement of gastric juice bile acid levels, manometric, endoscopic and X-ray study in health and benign gastrointestinal diseases and during exercise. DRG is shown to fall in the physiological events that have a biologically determined circadian rhythm. There was an association of DGR with gastric secretion. The "refluctant dilution effect" was established which along with elimination provides a relative constancy of the concentrations of bile ACIDS FROM 0.025 TO 0.422 NG/ML. DGR regulation is effected by the coordinated motor and evacuatory performance of the gastroduodenal junction and duodenum which is described as a lock two-way system. It is concluded that DGR is involved in the formation of the internal gastric environment and hence plays a role in gastric digestion. The findings may be used in studies of the physiology of digestion and in clinical practice.

[Microflora of the gallbladder in chronic calculous cholecystitis and its antibiotic sensitivity].

The microflora of 100 gallbladders removed from patients operated for chronic calculous cholecystitis was studied. Eighty-two of them contained microorganisms: monocultures and associations in 42 and 40 gallbladders, respectively. The associations included 2 (22 per cent) or 3-6 microbial species (18 per cent). Gram-positive bacteria predominated in the microflora (72.9 per cent): staphylococci (30 per cent), bifid and lactic acid bacteria (26 per cent), and spore-forming aerobic bacteria (21 per cent). The number of gram-negative bacteria amounted to 27.1 per cent. Among them the number of E. coli amounted to 21 per cent. On the whole the isolates were sensitive to neomycin, monomycin, carbenicillin and tetracycline. 91.1 per cent of the strains were sensitive to 2-18 antibiotics.

[Complex assessment of bile duct anastomoses].

Under study were the remote results of choledochoduodenostomy performed by convenient surgical methods and after valvular biliary-intestinal anastomoses by roentgenological fibroduodenoscopic, bacteriological investigations. The valvular anastomoses were shown to have evident advantages. The combination of valvular anastomoses with the correction of disturbed duodenal permeability, if they had been revealed before the operation, was found to be a preferable method. The data are based on the remote results in 80 patients in the terms from 1 to 19 years.
