Hydrogen Accumulation and Distribution in Pipeline Steel in Intensified Corrosion Conditions.

Hydrogen accumulation and distribution in pipeline steel under conditions of enhanced corrosion has been studied. The XRD analysis, optical spectrometry and uniaxial tension tests reveal that the corrosion environment affects the parameters of the inner and outer surface of the steel pipeline as well as the steel pipeline bulk. The steel surface becomes saturated with hydrogen released as a reaction product during insignificant methane dissociation.

[Comparison of Doppler-assisted dearterialization with mucopexy and hemorrhoidectomy].

Aim: To compare two methods of hemorrhoid treatment.

Material And Methods: This prospective study included 240 patients with hemorrhoids stage III-IVA. Stages III and IVA were diagnosed in 156 (65%) and 84 (35%) patients respectively.

[Rectosacropexy in rectal prolapse management].

Aim: To compare results of rectosacropexy and posterior-loop rectopexy in rectal prolapse management.

Material And Methods: Study included 122 patients operated for rectal prolapse for the period January 2007 to August 2014. Patients' age ranged from 19 to 85 years (mean 47.

[Surgical treatment of patients with severe fecal incontinence].

The objective of the study is improvement of clinical and functional results of surgical treatment of patients with severe fecal incontinence. 79 patients with complete fecal incontinence were included in the study. The technique of surgical intervention was choosed in depending on the localization of structural and functional disorders of the rectum closing apparatus.

Enhanced subthreshold e+ e- production in short laser pulses.

The emission of e+ e- pairs off a probe photon propagating through a polarized short-pulsed electromagnetic (e.g., laser) wave field is analyzed.

Near-threshold Lambda(1520) production by the gamma(p)-->K{+}Lambda(1520) reaction at forward K+ angles.

Differential cross sections and photon-beam asymmetries for the gamma(p)-->K{+}Lambda(1520) reaction have been measured with linearly polarized photon beams at energies from the threshold to 2.4 GeV at 0.6 View Article and Find Full Text PDF

Near-threshold diffractive psi-meson photoproduction from the proton.

Photoproduction of a phi meson on protons was studied by means of linearly polarized photons at forward angles in the low-energy region from threshold to Egamma = 2.37 GeV. The differential cross sections at t = -|t|min do not increase smoothly as Egamma increases but show a local maximum at around 2.

[Results of ligature of distal branches of the upper rectal artery in chronic hemorrhoid with the assistance of Doppler ultrasonography].

In October 2000 to February 2002 Doppler ultrasonography assisted suturing and ligation of hemorrhoidal arteries were performed in 102 patients with chronic hemorrhoids (57 men, 45 women, mean age 44 +/- 4.3 years). The mean duration of the disease was 10 +/- 4.

[Use of modified irrigoradioscopy in the diagnosis of external and internal rectal prolapse].

The paper gives colonic X-ray findings in 39 patients with rectal prolapse. Of them, 20 and 19 patients were found to have internal and external rectal prolapse, respectively. Studies were conducted by the modified irrigoscopy developed by the State Coloproctology Research Center, Ministry of Health of the Russian Federation, to explore the anatomic and functional status of the rectum and the fundus of the pelvis in patients with impaired defecation.

[The treatment of wounds of the anal canal and perineum].

Analysis of processes of wound healing in 215 patients after operations for hemorrhoids, anal fissures and rectal fistulas was carried out. Clinico-cytologic control of healing of postoperation wound has shown that ultra-violet irradiation of wound surface is most effective at early stages of wound healing due to its pronounced bactericidal and antiinflammatory action. Low frequency laser irradiation intensifies tissue reparative and hastens healing of wounds.

[Aseptic laser half-closed anastomoses in surgery on the hollow organs of the gastrointestinal tract].

The authors have modified the well-known methods of anastomosing between hollow organs of the gastrointestinal tract using radiation and intestinal forceps with narrow branches. The amount of inflammatory and purulent complications decreased.

[Formation of closed aseptic anastomosis of the hollow organs with the use of laser].

The authors modified the method for formation of aseptic anastomosis, using radiation of the CO2-laser and neodymium-doped YAG laser. The techniques for placing the enteroenteric anastomosis, gastroentero- and cholecystojejunoanastomosis are presented. Reduction in incidence of inflammatory and purulent postoperative complications has been achieved.

[Treatment of suppurative diseases of soft tissues by CO2 laser and immobilized trypsin].

The results of treatment of 245 patients with purulent diseases of the soft tissues are discussed. The course of the wound process was most favourable with the use of immobilized trypsin on gauze in the management of wounds formed after surgical debridement of purulent foci by means of CO2 laser. The method made it possible to accelerate the processes of necrolysis, provide a stable low level of dissemination of bacteria in the wound tissues, reduce the term of preparation of the wound for the application of secondary sutures and the terms of healing.

[Characteristics of wound process after high-energy laser debridement and enzyme treatment].

The results of ++clinico-bacterial examination of 168 patients provide evidence for the efficacy of CO2-laser treatment of a purulent wound; it reduces contamination of the tissues, 1,000-10,000-fold as a result of which surgical debridement of the purulent wound is completed in most cases by the application of a primary suture. The use of immobilized proteolytic enzymes in the postoperative period facilitates further cleansing of the wound, prevents the development of secondary infection, accelerates the change of the wound process to the phase of regeneration, promotes an uneventful postoperative course and healing of the wound within a lesser period as compared to the control group.

[A bioluminescent method of determining the sensitivity of microflora to antibiotics].

A bioluminescent rapid method (a three-hour test) has been developed to assess the susceptibility of microflora to antibiotics. It is based on comparison of intracellular ATP content in a sample (pus) after 3 h incubation at 37 degrees C in liquid culture medium (dilution: sample/culture medium--1:9) on a shaker in the presence and absence (control) of a single antibiotic concentration. A criterion has been offered for quantitative estimation of antibiotic susceptibility of microorganisms.
