Reducing the complications of the peritoneal dialysis (PD) procedure prolongs its use. The purpose of the work was to justify prolongation of peritoneal dialysis by modifying its setting. The study included 54 patients with chronic renal insufficiency, they carried out laparoscopic setting of PD; 14 patients were with omentopexy and 40 – with a classical statement. The operation was performed under general anesthesia. Surgical tactics were as follows: omentum folds were fixed to the parietal peritoneum; the control catheter was inserted through the window into the mesentery of the colon, and the dialysis portion at the bottom of the pelvis; sutured the window of the mesentery of the colon. Before insertion of the camera port, pneumoperitoneum was induced with a Veress needle, 10 mm below the navel. The pressure of abdominal gas was 12 mm Hg. Art. The point of entry into the abdominal cavity was established by the Hassan method: 5 cm lateral and 7 cm below the navel along the outer edge of the rectus abdominis muscle. A control catheter was inserted into the window under the transverse colon and inflated the balloon, the omentum was fixed to the parietal peritoneum 3 cm above the navel and the window in the colon mesentery was sutured. All early and late postoperative complications of the patients were recorded for 12 months (wound infections, including “tunnel infection”, dialysate leakage past the catheter, obturation of the catheter lumen, loss of tightness of omentoperitoneopexy). The study included 8 men and 6 women, aged from 43 to 76 years, of whom 2 patients had previously been operated on the abdominal organs. The operative intervention time averaged 54,6±15,4 min. No obstruction, catheter migration, or “tunnel infection” was established during the study. We have developed a laparoscopic technique of peritoneopexy of the upper half of the abdominal cavity, which will be used when the resource of the lower half of the abdominal cavity is exhausted and the effectiveness of preventing mechanical complications of the catheter PD has been proven.

1. When a guinea pig with well developed peritoneal tuberculosis is injected intraperitoneally with about 20 cc. of a heavy suspension of a virulent tubercle bacillus (Culture H37) death occurs within 24 hours or the animal becomes extremely toxic. Such a peritoneal tuberculosis develops in about 1 month after 1 cc. of. a very heavy suspension of Culture H37 has been introduced into the abdominal cavity. If the viscid fluid which is contained within the peritoneal cavity is mixed with saline solution and passed through a Berkefeld filter a bacillus-free filtrate is obtained which induces in normal guinea pigs a certain degree of cutaneous hypersensitiveness to tuberculin. 2. The abdominal organs and the parietal peritoneum, to which masses of leucocytes and tubercle bacilli are adherent, when crushed and extracted with saline solution yield a filtrate which likewise induces a cutaneous hypersensitiveness. 3. The cutaneous hypersensitiveness does not appear before the 7th or 8th day after the filtrate injection and is therefore considered to be the result of an active sensitization of the animal.

The aim of the study is to compare the mesh implantation and the strength of the mesh fixation to the anterior abdominal wall by modelling the intraperitoneal onlay mesh repair (IPOM) with and without aponeurotic defect closure. Materials and methods: The experimental animals were randomly divided into 2 groups of 6 rabbits. In experimental group IPOM was modelled without hernia defect closure, in control group – with its suturing. The macroscopic assessment of the severity of adhesions, histological examination of the removed “anterior abdominal wall – mesh” complex and strength of the mesh fixation to the anterior abdominal wall were performed on the 90th day. Results: In both groups, the displacement or complete separation of the mesh from the parietal peritoneum was not observed. The extent of adhesion formation in the abdominal cavity and strength of the mesh fixation are comparable in both groups (p > 0.05). In the experimental group, the mesh was surrounded by scar tissue, mesothelioma lining was not traced. There were also moderate signs of inflammation, which were not seen in the control group. Conclusions: The strength of the mesh fixation to the parietal peritoneum and its implantation into the anterior abdominal wall is comparable with or without aponeurotic defect closure during the experimental modelling of IPOM.

Abstract Background and study aims Endoscopic full-thickness resection (EFTR) is a useful procedure that allows minimal resection of the gastric wall because the tumor can be located endoscopically. However, the procedure carries a risk of peritoneal infection or dissemination. Thus, we devised a new EFTR technique in which the serosa is sealed using a silicone sheet to prevent the escape of gastric juice. Materials and methods Three whole stomachs were harvested from pigs for an ex vivo experiment, and seven pigs were used for an in vivo experiment. In both experiments, silicone sheets and gauze were pasted to the serosa using a fibrinogen-thrombin solution. A seromuscular incision was then made endoscopically using a HookKnife. We then evaluated whether stomach collapse could be prevented using this technique. Furthermore, the method was compared with conventional laparoscopic-assisted EFTR (LA-EFTR) in terms of resection time and quality of endoscopic view. Results In the ex vivo experiment, stomach collapse was suppressed and the seromuscular layer could be incised layer by layer. In the in vivo experiment, the time required for seromuscular incision with the new EFTR technique was significantly shorter than that with the conventional method. All layers of the stomach were smoothly resected under good endoscopic view. Conclusions Sealed EFTR is a potentially useful technique for the minimally invasive resection of gastric tumor. All layers of the stomach could be incised while confirming the incision line from the inside of the stomach and avoiding exposure of the tumor to the abdominal cavity.

We have reported the dependence of the magnetic and recording properties of CoPtCr recording media on the thickness of the Cr underlayer. It was inferred from XRD data that grain-to-grain epitaxy of the Cr with the CoPtCr was responsible for the interaction observed between these layers. However, no cross-sectional TEM (XTEM) work was performed to confirm this inference. In this paper, we report the application of new techniques for preparing XTEM specimens from actual magnetic recording disks, and for layer-by-layer micro-diffraction with an electron probe elongated parallel to the surface of the deposited structure which elucidate the effect of the crystallographic structure of the Cr on that of the CoPtCr.XTEM specimens were prepared from magnetic recording disks by modifying a technique used to prepare semiconductor specimens. After 3mm disks were prepared per the standard XTEM procedure, these disks were then lapped using a tripod polishing device. A grid with a single 1mmx2mm hole was then glued with M-bond 610 to the polished side of the disk.

The high quality thin films of high-Tc superconducting oxide are necessary for elucidating the superconducting mechanism and for device application. The recent trend in the preparation of high-Tc films has been toward “in-situ” growth of the superconducting phase at relatively low temperatures. The purpose of “in-situ” growth is to attain surface smoothness suitable for fabricating film devices but also to obtain high quality film. We present the investigation on the initial growth manner of YBCO by in-situ reflective high energy electron diffraction (RHEED) technique and on the structural and superconducting properties of the resulting ultrathin films below 100Å. The epitaxial films have been grown on (100) plane of MgO and SrTiO, heated below 650°C by activated reactive evaporation. The in-situ RHEED observation and the intensity measurement was carried out during deposition of YBCO on the substrate at 650°C. The deposition rate was 0.8Å/s. Fig. 1 shows the RHEED patterns at every stage of deposition of YBCO on MgO(100). All the patterns exhibit the sharp streaks, indicating that the film surface is atomically smooth and the growth manner is layer-by-layer.

At present time the interest is growing considerably for theoretical and experimental analysis of back-scattered electrons (BSE) energy spectra. It was discovered that a special angle and energy nitration of BSE flow could be used for increasing a spatial resolution of BSE mode, sample topography investigations and for layer-by layer visualizing of a depth structure. In the last case it was shown theoretically that in order to obtain suitable depth resolution it is necessary to select a part of BSE flow with the directions of velocities close to inverse to the primary beam and energies within a small window in the high-energy part of the whole spectrum.A wide range of such devices has been developed earlier, but all of them have considerable demerit: they can hardly be used with a standard SEM due to the necessity of sufficient SEM modifications like installation of large accessories in or out SEM chamber, mounting of specialized detector systems, input wires for high voltage supply, screening a primary beam from additional electromagnetic field, etc. In this report we present a new scheme of a compact BSE energy analyzer that is free of imperfections mentioned above.

III-V semiconductor films nucleate by the Stranski-Krastanov (SK) mechanism on Si substrates. Many of the extended defects present in the films are believed to result from the island formation and coalescence stage of SK growth. We have recently shown that low (-30 eV) energy, high flux (4 ions per deposited atom), Ar ion irradiation during nucleation of III-V semiconductors on Si substrates prolongs the 1ayer-by-layer stage of SK nucleation, leading to a decrease in extended defect densities. Furthermore, the epitaxial temperature was reduced by >100°C due to ion irradiation. The effect of ion bombardment on the nucleation mechanism was explained as being due to ion-induced dissociation of three-dimensional islands and ion-enhanced surface diffusion.For the case of InAs grown at 380°C on Si(100) (11% lattice mismatch), where island formation is expected after ≤ 1 monolayer (ML) during molecular beam epitaxy (MBE), in-situ reflection high-energy electron diffraction (RHEED) showed that 28 eV Ar ion irradiation prolonged the layer-by-layer stage of SK nucleation up to 10 ML. Otherion energies maintained layer-by-layer growth to lesser thicknesses. The ion-induced change in nucleation mechanism resulted in smoother surfaces and improved the crystalline perfection of thicker films as shown by transmission electron microscopy and X-ray rocking curve studies.
