Laughlin anyon complexes with Bose properties.

Two-dimensional electron systems in a quantizing magnetic field are regarded as of exceptional interest, considering the possible role of anyons-quasiparticles with non-boson and non-fermion statistics-in applied physics. To this day, essentially none but the fractional states of the quantum Hall effect (FQHE) have been experimentally realized as a system with anyonic statistics. In determining the thermodynamic properties of anyon matter, it is crucial to gain insight into the physics of its neutral excitations. We form a macroscopic quasi-equilibrium ensemble of neutral excitations - spin one anyon complexes in the Laughlin state ν = 1/3, experimentally, where ν is the electron filling factor. The ensemble is found to have such a long lifetime that it can be considered the new state of anyon matter. The properties of this state are investigated by optical techniques to reveal its Bose properties.

[Biological role of carnosine and its use in ophthalmology (mini-review)].

Carnosine (beta-alanyl-L-histidine) exhibits various biological effects underlying its potential therapeutic use. In ophthalmology carnosine was effective in treatment of corneal metabolic diseases, senile cataract. It accelerated cornea reepithelization after photorephraction ceratoectomia.

[Diseases of fatty appendices of the colon]. / Zabolevaniia zhirovykh podveskov obodochnoi kishki.

Seventy-one patients with volvulus of fatty appendix of the colon (sigmoid colon--52 patients, caecum--12, ascending colon--5, vermicular appendix--2 patients) were treated. Volvulus of epiploic appendix was seen in 67.6% operated patients, inflammatory changes--in 28.1% (primary inflammation was diagnosed in 4.2% patients). Symptoms of fat metabolism disorders were detected in 44 patients. There are no specific symptoms. Diagnostic laparoscopy permitted to improve diagnosis of epiploic appendices diseases. Target surgical approach permitted to reduce rate of postoperative complications and to improve results of treatment.

[Valvular pyloroplasty in the treatment of pyloroduodenal ulcers]. / Klapannaia piloroplastika v lechenii oslozhnennykh piloroduodenal'nykh iazv.

Original method of treatment of complicated pyloroduodenal ulcers is proposed. The results of different organ-saving operations in complicated pyloroduodenal ulcers were analyzed in 136 patients aged from 15 to 89 years. Evaluation of the results was based on the data obtained during study of secretory and motor-evacuatory function of the stomach, state of gastric and duodenal mucous membrane, degree of duodenogastric reflux. Gastroscopy in remote period after organ-saving operations enabled visual evaluation of state of anew formed pyloric canal. Results of treatment of complicated pyloroduodenal ulcers by different methods of pyloroplasty demonstrate the advantages of valvular pyloroplasty.

[Treatment of patients with foreign bodies in rectum]. / Lechenie bol'nykh s inorodnymi telami priamoi kishki.

The analysis of treatment results in 112 patients with foreign bodies in the rectum, aged from 16 to 80 years, was carried out. 99.1% of the patients were men. All the patients were examined and treated in proctology department of the Moscow municipal clinical hospital N 67 from 1969 to 1998. The examination was made by standard scheme, including rectal touch, rectoromanoscopy, X-ray and ultrasonic examinations. In 107 patients the foreign body was removed without surgery, 5 patients required laparotomy. When possible it was removed by fingers and also with use of forceps. When small foreign bodies could not be reached by finger, they were removed through rectoscope. Foreign bodies of big sizes, proximal end of which was in the sigmoid colon, were removed under anasthesia with the help of the assistant who fixed the foreign body through the abdominal wall in the left ileac region. In impossibility of the subject removal by these methods and presence of complications (perforation, peritonitis), laparotomy with subsequent transanal subject removal without colon section was performed, in case of perforation--with wound suturing or colostomy.

[Surgical treatment of extraperitoneal rectal and perineal injuries]. / Khirurgicheskoe lechenie vnebriushinnykh ranenii priamoi kishki i promezhnosti.

The aim of this study was to analyse the results of the treatment of extraperitoneal rectal and perineal injuries for 153 patients. All the patients were examined according to the scheme. Therapeutic-diagnostic algorithm was developed for perineal, anal, rectal injuries. Wide opening and drainage of the wound was used. The method allows to avoid colostomy and its subsequent operative closing in extraperitoneal injury of the rectum. The method of surgical treatment is recommended in extraperitoneal rectal and perineal injuries.

[Nonoperative treatment of liver superficial injuries]. / Neoprativnoe lechenie poverkhnostnykh povrezhdenii pecheni.

The study is based on the results of conservative and operative surgical treatment of 184 victims with open and closed, isolated and combined injuries of the liver. The patients' age was from 15 to 80 years. All patients were examined and treated in 1991 to 1996 in Moscow clinical hospital No 67. Conservative treatment for superficial injuries of the liver were carried out in 72 patients. 112 patients underwent urgent operations. Conservative treatment included: examination, control diagnostic laparoscopy and introduction of control drainage followed by dynamic laparoscopy. Operative treatment included: laparotomy, revision of the abdominal cavity, sutures or resection of the liver, surgical treatment of the other abdominal organs. Comparative analysis of two methods of treatment demonstrated possibility and necessity of the use of conservative treatment for superficial injuries of the liver, especially in combined traumas.

[Liver injuries]. / Povrezhdenie pecheni.

The analyses of literature data on the results of the treatment of patients with mechanical injuries of the liver have been done. Analyses of 458 cases of open and closed liver traumas made it possible to determine 2 clinical forms of liver injuries: hemorrhagic and peritoneal. The separate subforms of traumatic liver disease in isolated multiple and combined injuries are determined. A diagnostic role of various methods was evaluated. Use of laparoscopy in 17 patients has exposed a superficial character of liver injuries and allowed not to perform surgery. Use of low-frequency ultrasound and polymeric adhesive sulfacrilat for the treatment of liver wounds in 63 patients has decreased the rate of postoperative complications to 18%, and the rate of mortality in mechanical liver injuries to 11.4% (in patients with mechanical liver injuries operated on with the use of ligature-free suture).

[Microflora in patients with complicated forms of acute cholecystitis treated by low-frequency ultrasonics and sulfacrylate glue]. / Dinamika mikroflory u bol'nykh s oslozhnennymi formami ostrogo kholetsistita, lechennykh nizkochastotnym ul'trazvukom i sul'fakrilatnym kleem.

Investigation of microflora in patients with complicated acute cholecystitis treated with low frequency ultrasound in combination with sulfacrylate glue showed that Staphylococcus and Escherichia played the leading role in the complication etiology. Among the nonsporulating organisms bacteroides predominated. The combined use of low frequency ultrasound and sulfacrylate glue in treatment of complicated acute cholecystitis proved to be an efficient procedure providing more rapid sanation of the purulent inflammation foci.
