[Dependence of effects of weak combined low-frequency variable and constant magnetic fields on the intensity of asexual reproduction of planarians Dugesia tigrina on the magnitude of the variable field]. / Zavisimost' vliianiia slabykh kombinirovannykh nizkochastotnykh peremennykh i postoiannykh magnitnykh polei na intensivnost' bespologo razmnozheniia planarii Dugesia tigrina ot velichiny peremennogo polia.

It was shown that the stimulating effect of weak combined magnetic fields (constant component 42 microT, frequency of the variable component 3.7 Hz) on the division of planarians depends on the amplitude of the variable component of the field. The effect is particularly pronounced at 40 (the main maximum), 120, 160, and 640 nT. Narrow ranges of effective amplitudes alternate in some cases with equally narrow ranges in which the system does not respond to he treatment. In the range of super weak amplitudes of the variable field (0.1 and 1 nT), the stimulating effect is poorly pronounced. The data obtained indicate the presence of narrow amplitude windows in the response of the biological systems to weak and super weak magnetic fields. In a special series of experiments, it was shown that the effect of fields on planarians is partially mediated via aqueous medium preliminarily treated with weak magnetic fields. It is noteworthy that in experiments with water treated with weak magnetic fields, there were no pronounced maxima and minima in the magnitude of the effect in the range of amplitude of the variable magnetic field from 40 to 320 nT.

[Hydrolysis of the bovine insulin B-chain in bidistilled modified water]. / Gidroliz B-tsepi insulina byka v bidistillirovannoi modifitsirovannoi vode.

It was shown that bidistilled modified water substantially enhances the hydrolysis of the peptide the bovine insulin B-chain. The exposure of the peptide to bidistilled modified water for 20 hours at room temperature leads to an almost complete hydrolysis of its molecule into fragments that differ from the initial molecule in elution time from a column in high-performance liquid chromatography.

[The clinico-microbiological and epidemiological aspects of hospital infections in a surgical clinic]. / Kliniko-mikrobiologicheskie i épidemiologicheskie aspekty gospital'nykh infektsii v khirurgicheskoi klinike.

Complex clinical and microbiological and epidemiological study of specificity of hospital infections was conducted in surgical clinics of Military and Medical Academy. Analysis of the materials obtained has permitted to develop the classification of agents of modern hospital surgical infections, to study the variety and specificity of forming of microorganism hospital strains. To optimize the system of sanitary and epidemiological inspection on hospital infections and to improve their prophylaxis it is proposed to introduce into the practice of bacteriological laboratories of military medical and prophylactic institutions the quantitative microbiological examinations of clinical material. Besides it is reasonable to have in the stuff of multipurpose military hospitals the post of hospital epidemiologist trained in the actual problems of clinical microbiology, hospital hygiene and surgical infection.

[The problems in and the means for improving ambulatory surgical care in the Armed Forces]. / Problemy i puti sovershenstvovaniia ambulatornoi khirurgicheskoi pomoshchi v Vooruzhennykh Silakh.

The article presents some conclusions on ambulatory surgery in the Military Medical Academy and Surgery Centers in St. Petersburg resulting in higher efficiency of surgical aid and its availability for military beneficiaries. Organization frames and staffing principles for day-time ambulatory surgery stations.

[Synthesis of oligopeptides from the polar amino acids in water media by the combined action of weak electric and magnetic fields]. / Sintez oligopeptidov iz poliarnykh aminokislot v vodnoi srede pri kombinirovannom deistvii slabykh élektricheskikh i magnitnykh polei.

The effect of weak electromagnetic fields on aqueos solutions of polar amino acids leads to the formation of stable products of the amino acid condensation reaction. These products have a definite amino acid composition and retention time in high-performance liquid chromatography.

[Ambulatory surgery in St. Petersburg]. / Ambulatornaia khirurgiia v Sankt-Peterburg.

The authors describe preconditions of structural reorganization of the work of medical institutions of the ambulatory-polyclinical link of St. Petersburg in order to improve surgical treatment of the population. Main organizational principles underlying the work of ambulatory surgery centers are shown, results of their activities during the recent years are discussed. The advantages resulting from activities of day-time surgical hospitals are also described.

[Improving the ambulatory surgical services on the basis of the work experience of the Center of Ambulatory Surgery]. / Sovershenstvovanie ambulatornoi khirurgicheskoi pomoshchi po opytu raboty Tsentra ambulatornoi khirurgii.

Centers of ambulatory surgery made on the basis of large city polyclinics and regional medical formations are considered to be a perspective and economically effective form of perestroika of the ambulatory surgical aid to people. Specificity of the operative procedures performed at the Center and specific features of postoperative management of the patients should be taken into consideration, and the staff of such units must consist of highly trained surgeons of wide type. The ambulatory surgery Center must occupy its place in the system of dispensary examinations of the population.
