[Structure-functional studies of the White sea water and bottom sediments].
Statistical analysis of dynamic indices of biopolymers enzymatic destruction in unstratified and stratified. White Sea water has revealed specific properties of protease and amylase activities. We analyzed the component composition and hydrolytic enzymatic activities in the surface layer of the bottom sediments (0-2 cm). The relationship between protease and amylase enzymatic activities in the surface sediments with different content of pelite fraction is discussed.

[To the ways of the most reasonable implementation of digital radiography into the practical public health of the Russian Federation].
The main idea of the authors' paper is to propose the most reasonable way of actively introducing the digital principle into the traditional roentgenological section of radiation diagnosis. For this, a luminophore digital radiography system has been chosen. The authors of the paper give a full-scale assessment and appropriate recommendations for its use. The paper essentially discusses the entire complex of matters that permit assessment whether its sound use is possible in regional and municipal health care systems. This is both a section devoted to a dose load, by making a comparative assessment of luminophore radiography and "the green system" and a study of different clinical diseases (456 cases). In their study, the authors have applied an original principle in the formation of an image obtained and some other approaches in order to make a comprehensive assessment of this method. In the authors' opinion, luminophore radiography has a variety of advantages. Firstly, this technique can be simultaneously applied to several nondigital apparatuses, including those available in the ward and it shows a rather diagnostic effectiveness and economic profitability, yields a qualitative image of varying density tissues upon single exposure, and has some other capacities of the CR system as a digital technique. All this things considered, the authors consider that luminophore radiography may be one of the main ways of introducing a digital technique into the conventional roentgenological section of radiation diagnosis at the level of regional and municipal heath care systems.

[Role of digital X-ray study in the current diagnosis of gastric cancer].
The authors attempted to assess and provide evidence for the expedience of using a digital radiography CR system in clinical gastroenterology. The prerequisite for this was the results of large-scale diagnostic studies of different organ and systemic diseases. The authors underline the specific features of application of this digital system: the latter allows several analogue X-ray apparatuses to be transformed to digital ones, provides economic efficiency as compared with apparatuses with the direct digitization of an image, shows telemedical prospects, and has low radiation loads as evidenced by research and experimental studies even in comparison with green systems, which makes the use of these digital systems in X-ray gastroenterology highly tempting. Based on a great body of data from 126 studies, the authors could show the effectiveness of the digital radiography CR system in the diagnosis of gastric cancer, demonstrate a modernized approach to formatting an obtained digital image, the possibility of postprocessor treatment that can enhance the validity of existing X-ray symptoms. This all permitted the authors to recommend using the CR systems in the diagnosis of gastric cancer, by taking into account the current obvious predominance of its morphological diffuse and mixed forms and corresponding difficulties of their endoscopic diagnosis.

[The CR digital radiography system in traditional X-ray studies (according to the materials of the Moscow Regional Clinical Research Institute)].
The basic idea of the author's paper is to attempt to estimate and prove whether it is advisable to use the CR digital radiography system in a multidisciplinary therapeutic institution mainly at the municipal level. The pre-requisites for this were the results of diagnostic studies of different diseases of organs and systems. Emphasis is laid on the specific features of use of this digital system; namely, it can convert several analogue X-ray apparatuses to digital ones and it is more profitable than indirect image numeralization apparatuses and produces lower radiation loads. This all makes the use of these digital systems tempting in traditional X-ray study. A comparatively large material (4237 cases) was used to show the efficiency of the CR digital radiography system in the diagnosis of ENT diseases, osteology, interventional radiology, gastroenterology, pediatrics and to demonstrate a modernized approach to having a solid copy of a digital image, the possibilities of postprocessing that may enhance the validity of existing X-ray symptoms. This all allows the author to recommend that the CR digital radiography systems be used in traditional X-ray study for the diagnosis of various diseases occurring in a multidisciplinary health care facility mainly at municipal and regional levels.
