The author formulated the main contradition of the epidemic process consisting of contradiction between the interaction of the motive forces of the epidemic process, since this contradiction at the same time served as the imperative condition of the origination and as the cause of the subsequent arrest of the spread of infection. The main contradiction of the epidemic process is expressed in reduction of the number and limited activity of the sources of infection, attenuation or arrest of the mechanism of transmission of the causative agents, formation of immunity in the population, the appearance of hereditary resistance in the hosts to the causative agent of the infection. The action of the principal internal contradiction of the epidemic process in the course of evolution conditions genetic variability of the causative agents of the infectious diseases, intensification of the mechanisms of excretion of the parasites from the host organism, and increase of their resistance in the external environment, formation of latent forms of infection. 相似文献

In the work the factors, rendering essential influence on organization of donorship in modern army conditions are systematized. The organization of donorship should be connected to functioning of territorial system of medical maintenance of the Armed Forces of RF. It assumes presence of four organizational levels: central, district, zone and garrison. Perfecting the system of organization of donorship, we should be guided by the following conducting principles: maximum maintenance of safety of donorship; wide introduction of a method of plasmacytopheresis in work of establishments and subdivisions of blood supply service; organization of autodonorship and quota of the donors of an emergency reserve in each military-medical establishment; reliable maintenance of revealing of markers of hemotransmissible infections at inspection of the donors. 相似文献

Thermosensitive periods of the development of germs of separate pairs of macrochaetae were studied in two lines of mutation of scute Drosophila melanogaster (y/sc4B and cs7). The experiments have revealed the following three features which had not been observed earlier in similar investigations in other mutants of drosophila: 1) change of thermosensitivity in mutants sc7 in different periods of ontogenesis; 2) different sensitivity in mutants of both lines in different critical periods of the same pair of macrochaetae; 3) discrete sensitivity of separate macrochaetae in mutants of both lines at different stages of oogenesis when there are no germs of these organs yet. The change of penetrability of the mutation of scute for scuttellar macrochaetae in mutants y/sc4B caused by the 90-minute-long heating of larvae on the 4th day of their life (critical period of development) is inherited in 15 observed generations of the maternal line. One may consider these periods of the increased thermosensitivity to be tje periods of stepwise determination of germs of separate pairs of macrochaetae. 相似文献

The article describes dynamics of diseases of therapeutic field in the Armed Forces in 1991-1996. The analysis of therapeutic sick rate has confirmed, that a major problem of military therapy remains acute pneumonia, which sick rate in 1993-1996 has increased twice. The sick rate of ulcer has increased equally. The main directions of perfection of organization of the therapeutic care in the Armed Forces are etiologic diagnostics and prophylaxis of acute pneumonia in the soldiers, creation of system of prophylaxis, active revealing and centralized high-specialized treatment of the patient with ischemic heart disease among officers, perfection of system of rendering of the specialized care to the patient of endocrinological field, introduction of modern methods of anti-relapse treatment of ulcer, active revealing of the persons, infected by virus of hepatitis, perfection of work of an out-patient department link. 相似文献

The efficiency of USI of the neck, scintigraphy of the parathyroid glands (PTG) with selen-methionine and selective catheterization of veins (SCV) of the neck and mediastinum for preoperative determination of the localization of the source of hyperproduction of the parathyroid hormone was analyzed on the basis of results of examination of 149 patients including 51 patients with primary hyperparathyroidism confirmed during the operation. It was noted that none of the methods of topical diagnostics used in the work is thought to be universal for different clinical situations. A method of their complex use is proposed which foresee USI of the neck as the first step. In case of insufficient information of the results of USI the authors propose SCV of the neck and mediastinum as a method of choice which allows the size and level of the altered PTG to become more exact and which makes further search with the help of other methods of topical diagnostics more purposeful and effective. 相似文献

Conclusions The article presents the results of an investigation of the mechanical properties of samples of iron powder obtained by reducing martite ore by converted natural gas.The use of this raw material for producing iron powder for the needs of the powder metallurgy industry permits a considerable extension of the raw material reserves.As a result of the investigations the authors determined the characteristics of strength, plasticity and fatigue strength of material of varying porosity.The regularities of deformation of such materials and the strength characteristics of the duration of load application were studied.The results show that the strength and plasticity of metal powder materials of similar composition made of other kinds of iron powders. 相似文献

In result of own researches and analysis of the literature? the information about high sensitivity of neutrophils of peripheric blood to infringements of constancy of internal state of body, arising as reply to radiating influence, are received. Ionized radiation modulates greatly properties and functions of neutrophilic granulocytes, which are the most sensitive and high-modulated cells of non-specific resistance system. The changes of the functional-metabolic status of neutrophils in participants of liquidation of consequences of Chernobyl disaster have been saving during 10 years after influence of the extreme, including radiating, factors of failure. 相似文献

Transposons of gypsy group are assigned to LTR-containing retrotransposons present in the genomes of invertebrates, fungi, and plants. In this work, a theoretical analysis of the potential products of ORFs of these retrotranposons was conducted. Alignments were obtained and trees of similarity were constructed for domains of the POL region. On the basis of the obtained data, two hypothetically monophyletic subgroups of transposons were distinguished within the framework of the gypsy group, settling the genomes of taxonomically related organisms (the subgroup of "true" gypsy of insects and the subgroup of gypsy-like transposons of plants and fungi). A number of peculiarities of the topology of these trees hypothetically indicate cases of genetic conversion and recombination of domains accompanying the evolution of this group. The amino acid substitution fixation rate was evaluated on the basis of comparison of sequences of the protein products of ORFs. Estimates of the time of divergence of subgroups of gypsy-group transposons are significantly less than estimates of the times of divergence of their host species. One explanation for this discrepancy might be the hypothesis of settlement by transposons of the genomes of isolated host species. 相似文献

The effects of daily injections, over the course of 14 days, of 45 micrograms of phenamine, 5 micrograms of haloperidol and naloxone, 15 micrograms of leu-enkephalin and its analog, a tetrapeptide, into the rostral neostriatum have been studied. The chronic stimulation of the dopaminergic system of the striatum induced facilitation of the realization of an active avoidance conditioned reflex, and stimulated exploratory stereotypy, while its blockade led to suppression of conditioned reflex activity against the background of a clearcut rigid akinetic syndrome. The microinjections of leu-enkephalin and naloxone did not substantially alter the behavior, but the injection of the tetrapeptide was accompanied by changes in behavior, with symptoms of catalepsy and hyperkinesia. Injections of phenamine and haloperidol were accompanied by a decrease in the content of dopamine in the striatum and an increase in the level of DOPAC; the injections of enkephalin and naloxone induced changes of the reverse order. The possible causes of the noncorrespondence of the behavioral and neurochemical shifts in the presence of a direct chronic pharmacological action on the mediator of the neostriatum. 相似文献
