ABSTRACT
The article includes experience with treatment of 103 patients with the formed different large intestine anastomoses. Primary operations for cancer of the rectum were made on 76 patients, restorative operations--on 27 patients. The following techniques were used: manual formation of the large intestine anastomosis, apparatus anastomoses using AKA-2, "ETHICON CDH" and double apparatuses method using "CONTOUR" and "ETHICON CDH". It was found that the application of stitching apparatuses required shorter time necessary for applying large intestine anastomosis and for operation. When forming the large intestine anastomoses in the abdominal cavity the manual method should be preferred. The formation of anastomosis in the small pelvis cavity is accompanied by technical problems and requires using stitching apparatuses. The method using apparatuses "CONTOUR" and "ETHICON CDH" decreases the number of postoperative complications and can extend the list of indications for performing sphincter-sparing operations.

The responses of a chemostat Saccharomyces cerevisiae culture (D = 0.1 h-1) to a stepwise increase or decrease in the pH of the medium were shown to be asymmetric. When the pH was lowered from 6.5 to a value above 0.3, the rates of oxygen uptake and carbon dioxide evolution rose for a sort period of time whereas the optical density of the culture fell down. The detected changes in the properties of the culture were identical with those which had been observed in the course of spontaneous undamped oscillations in the physiological parameters of the continuous C. cerevisiae culture. Apparently, in both cases, the energy status of cells changed when the oxidative type of metabolism was substituted by fermentation. When the pH of the medium was elevated within the same range (4.7-6.5), the response of the culture was three times as low and its properties changed in the opposite direction. When the pH of the medium was changed in a cyclic sinusoidal manner, oscillations in the physiological characteristics of the culture, identical with spontaneous oscillations were induced at certain values of the amplitude and the frequency of pH changes.
