[Surgical policy in reconstructive surgery on the colon].

Thirty-year experience with 1685 reconstructive operations on the colon is analyzed. Novel surgical policy has increased the rate of primary-reconstructive operations for the last 5 years from 78.8 to 87.9%, decreased the number of postoperative complications from 33 to 21.8%, intestinal anastomosis-dependent complications -- from 22.6 to 8.4%, postoperative lethality -- from 6.9 to 2.4%, raised the rate of good functional results from 64 to 88.2%.

[Foreign body of bladder in children].

The thirty-years experience of diagnosis and treatment of the bladder foreign body in children was summarized. There were treated 19 children with the bladder foreign bodies in the clinic. There were 12 (63.12%) girls and 7 (36.88%) boys, aged from 3 to 15 years old. Three mechanisms of penetration of foreign bodies into the bladder were delineated: by retrograde way via urethra; while gun-shot wounding, trauma or due to migration from surrounding tissues and organs; as the consequence of faults, committed during performance of operations or therapeutic-diagnostic procedures. In 14 patients the foreign bodies were removed transvesically and in 5--transurethrally. All the patients had recovered. Complications did not occur. Late results were studied up.

[Comparative analysis of 2 sanitary-bacteriological methods of detecting bacteria of the Escherichia coli group in the environment].

A total of 965 parallel tests for coli bacilli were carried out using the wash-out or print methods in the course of sanitary and epidemiologic inspection of different objects. The methods used in the study were equally sensitive and provided compatible results which were in good correlation. The print method with bacterial tests is more rapid (by 24 hours) and helps detect other bacteria which grow in Endo's medium; moreover, it is three times cheaper than the labor-consuming wash-out method.

[Follow-up results of modified Glenn-Andersen operation in children with primary vesicoureteral reflux].

The results of operative treatment of 51 patients with primary vesico-ureteric reflux followed from 6 mos to 11 yrs were analyzed. Glenn-Andersen method modification of clinic was used. Conclusion was made about the advantages of one-moment bilateral ureters transplantation over the staged treatment in children with bilateral vesico-ureteric reflux. Good result was noted in 57 (77%) observations after 74 plastic operations.

[Choice of the method of surgical treatment of hydronephrosis due to congenital stenosis of the pyeloureteral segment].

The results of treatment of 139 patients with congenital pyelo-ureteric segment (PUS) narrowing were analyzed. Plastic operation was conducted in 117 of them, PUS plasty with the flap application--in 22. The prognostic significance of sign's norm deviations of the PUS diameter and length ratio as a risk factor was studied to substantiate the numerical criterion--of operation method choice. In accordance with this prognostic significance the value of Student's criterion was calculated. When the value of ratio is no more than 0.3--the narrowed part resection with subsequent ureteropelviostomy is indicated, and when this value is 0.31 or more--the PUS plasty with the flap application.

[Short- and long-term immune status in people after radiation injury as a result of the accident at the Chernobyl Nuclear Power Station].

Humoral and cellular factors of the immune system of 133 subjects injured in the Chernobyl accident were studied during first 1.5-2 months after radiation, 5-17 months and 3 years after they suffered acute radiation sickness (I-IV degree). Significant disorders in the immune system correlating with the severity of the disease were recorded. In late terms certain shifts persisted in the immune status of subjects who had suffered acute radiation sickness, II and III degree.

[Prevention of infectious complications in patients with acute bone marrow depression].

Clinical efficacy of intravenous gentamicin in combination with oral use of gentamicin, ristomycin and nystatin was studied in 1977. In 1980-1984 two antiinfectious regimens were tested: intravenous administration of gentamicin in combination with total decontamination (oral use of gentamicin and nystatin) and selective decontamination (biseptol with nystatin of amphoglucamine). It was shown that the incidence of severe infections in the patients under the observation dropped against the controls. The incidence and spectrum of infectious complications in cases with acute myelodepressions were proved to depend on the intestinal autoflora inhibition.

[The issue of paid medical care].

The paper deals with the problem of improving the relationships between the state system of public health and medical cooperatives and cost-accounting organizations with a view of increasing the efficiency and quality of health care delivery. It has been shown that the paid system of health care delivery is assuming ever greater importance. On the basis of one's own investigations and practical measures introduced in the Samara region, recommendations are given to improve the cooperation between the Department of Health and medical cooperatives, an analysis is made of the reasons for insufficient development of paid system of health care in the country.

[Experimental colonic prosthesis using xenograft materials].

The authors by means of electrohydrodynamic modelling on a resistance paper substantiated the sizes of a graft necessary for colonic prosthetics. In the experiment on 16 mongrel dogs, a possibility to use xenograft materials for plasty of the colon is shown.
