[ICG angiography in prevention of colorectal anastomotic leakage]. / Rol' ICG-angiografii v profilaktike nesostoyatel'nosti kolorektal'nykh anastomozov.

OBJECTIVE: To evaluate the effectiveness of indocyanine green fluorescence angiography in assessment of colorectal anastomosis perfusion. MATERIAL AND METHODS: A prospective single-center non-randomized comparative study included 85 patients with rectum and sigmoid colon cancer between September 2019 and March 2023. In the main group (n=41), we intraoperatively injected indocyanine green (ICG) IV to assess perfusion in the near infrared spectrum. In the control group (n=44), the same interventions were performed without ICG. RESULTS: In the main group, anterior resection of the rectum was performed in 23 (56.1%) patients with neoplasms of distal sigmoid colon and rectosigmoid tumors. Low anterior resection was performed in 18 (43.9%) cases. In the control group, the same procedures were carried out in 24 (54.5%) and 20 (45.5%) patients, respectively. After mobilization of the colon and ICG injection, we corrected resection line in 4 cases. As soon as anastomosis was formed and blood supply was controlled by ICG fluorescence angiography, we performed a water-bubble test to detect anastomotic leakage. Positive tests were detected in 4 (9.8%) and 5 (11.4%) patients of both groups, respectively. Postoperative complications occurred in 10 (24.4%) and 11 (27.3%) patients, respectively (p=0.94). Anastomosis failure was found in 1 and 7 patients, respectively. Anastomotic leakage grade «B¼ was significantly more common in the control group (2.4 and 13.6%, respectively, p=0.06). Anastomotic leaks were absent in all 4 patients who underwent resection level adjustment after intraoperative ICG angiography. CONCLUSION: Fluorescent luminescence will qualitatively improve intraoperative diagnosis of hypoperfusion of resection edges. Undoubtedly, this will reduce the incidence of colorectal anastomotic leaks caused by ischemia of large bowel wall.

[Adequate and clinically effective levels of curcumin consumption].

Despite the existence of sufficiently effective drug therapy, interest in additional dietary interventions that improve the clinical condition of patients with the most common alimentary diseases is constantly growing; as well as the inclusion of biologically active compounds (BAC) of plant origin as functional ingredients in foods for special dietary uses (FSDU) and dietary supplements is intensively developing. The purpose of the review is comparison of curcumin doses allowed for use in dietary supplements and FSDU with doses that provide a clinical effect, as well as an analysis of ways to increase curcumin bioavailability. Material and methods. A review of the existing literature on the problem in recent years was carried out using the databases of the Russian Science Citation Index, PubMed, ResearchGate. Results. The amount of BAC added to the FSDU in the daily portion has been established by domestic regulatory documents. The allowed maximum level in FSDU for curcumin is 150 mg per day. Literature analysis has shown that effective doses of turmeric are 320- 1670 mg per day when consumed for 10-12 weeks. The main barriers for using curcumin at lower doses are its low water solubility, rapid metabolism and elimination from the body, and therefore poor bioavailability. Curcumin bioavailability can be increased by including it in liposomes, phospholipid complexes, emulsions, oleogels, hydrogels, etc. Conclusion. Curcumin content in FSDU in an amount that does not reach doses with efficacy proven in a certain pathology, and the inclusion of such FSDU in the diet for a short period does not allow to achieve the expected result. A promising approach to achieve a clinical effect at lower doses of curcumin is the use of new technological methods to increase bioavailability.

[Technological features of fermented beverages production using kombucha].

Kombucha is a beverage made by fermenting sweetened brewed tea (substrate) by symbiotic culture of yeast and bacteria. Numerous researches on optimization of fermentation process, determination of the influence of technological factors on physical and chemical properties, formation of taste and flavor profile of the beverages, prevention of industrial product risks are due to the growing popularity of kombucha in Europe and the USA. Technological features of kombucha production are to optimize conditions for the growth of symbiotic culture and substrate fermentation. The duration of the process depends on the composition of the substrate, the ratio of tea mushroom and substrate, temperature, size and shape of fermentation vessel. The aim of the work was to generalize the results of studying the technological features of the production of fermented kombucha type beverages and to identify the factors that affect the chemical composition and safety of the finished beverages. Material and methods. Analytical research was carried out on the main databases for the keyword "kombucha". The criteria for inclusion of articles in the analysis were research articles with open access and presenting detailed technology of kombucha. Results. The technology of kombucha production is based on fermentation of the substrate and obtaining the base of the beverage with high content of organic acids, mainly acetic acid. In order to ensure microbiological safety the acetic acid concentration in the beverage base must be at least 1.2%. The high organic acid content necessitates the use of only glass or stainless steel fermentation equipment approved for food contact. The fermentation temperature ranges from 18 to 32 °C. The fermentation process is monitored according to basic criteria: temperature, pH value, acidity, acetic acid content, ethyl alcohol content, and residual sugar content. Kombucha production process is connected with microbiological, chemical and physical risks which could appear in case of using low quality raw materials, equipment and consumer packaging made of materials which do not correspond to sanitary norms, violating technological regimes, storage conditions of raw materials and ready production. To prevent hazards affecting the quality and safety of the finished product, it is necessary to control the technological process at all stages of production. Conclusion. Following sanitary-hygienic norms and technological regimes allows producing kombucha with a balanced taste and aroma, which meets the safety requirements for fermented beverages.

[Russian market of fermented kombucha beverages].

Fermented beverages based on kombucha contain a wide range of minor biologically active substances (flavonoids, caffeic acid derivatives, B vitamins, and others). The inclusion of these beverages in the diet helps to increase its nutritional value due to the content of biologically active substances, including essential ones. To develop beverages (kombucha) with a certain content of biologically active substances, it is necessary to study the composition of these products sold on the Russian market. The aim of the work was to analyze the Russian market of fermented beverages based on kombucha. Material and methods. More than 100 different marketed products were selected, positioned as non-alcoholic fermented beverages based on kombucha. Results. It was revealed that black tea (~28%), green tea (~24%) and Blooming Sally (~13%) are most often used as the basis for kombucha. In other cases, various types of tea, coffee, as well as special varieties of tea are used. Sugar (~55%), stevia extract (~24%), as well as honey, fructose, glucose-fructose syrup are used as sweeteners. The formation of the flavor profile of kombucha is achieved by using additional ingredients. A variety of fruits (lemon, orange, mango, apple, etc.), vegetables (cucumber, beetroot, etc.), berries (cranberries, lingonberries, chokeberry, raspberries, etc.) are used in the form of juices or purees; herbs and spices (mint, nutmeg, star anise, cloves, lavender, vanilla, etc.), as well as functional ingredients (vitamins, prebiotics, probiotics, chlorophyll) are applied as such additives. Conclusion. The analysis of the range of fermented drinks (kombucha) marketed in trading network was carried out. A list of main and auxiliary ingredients has been formed to assess the possibility of using these drinks to modify eating patterns.

[Formation of the organoleptic profile of sugar cookies with a modified fat component].

Currently, as part of solving the problems of improving the quality and safety of food, research is underway on the introduction of oleogels into foodstuffs to replace solid fats, which contain saturated and trans-isomeric fatty acids. However, such a replacement leads to a change in the organoleptic characteristics of food. The aim of the work was to identify the characteristics that affect the difference in the perception of cookie descriptors baked using hard fat and oleogels. Material and methods. Three batches of sugar cookies samples with different fat components were produced for the study: butter cookies; cookies based on oleogel structured with beeswax; and cookies based on oleogel structured with combinations of beeswax fractions. Organoleptic evaluation was carried out by two methods: the triangle method according to ISO 4120:2004 and the free-choice profiling method according to ISO 13299-2015. In this case, the profile was derived statistically, by means of a generalized Procrustes analysis. Results and discussion. The analyze of cookies samples using the triangle method showed there was no noticeable difference between the control cookies samples and cookies with oleogel structured with beeswax, but there were significant differences with cookies baked with the use of oleogel structured with a combination of fractions. Generalized Procrustes analysis was used to interpret the results of the descriptor profile analysis. It was shown that differences in perception between samples were due to the severity of the following descriptors: Creamy flavour, Fat flavour, Floral flavour, Waxy flavour, Shape. A close correlation has been established between individual descriptors characterizing the samples under study. Conclusion. The data obtained as a result of the conducted studies allow not only to judge the acceptability of the use of oleogels in cookies from an organoleptic point of view, but also to identify individual characteristics that affect the perception of cookie samples. In the future, this information can be used to optimize the formulation of finished cookies containing oleogels in order to change the organoleptic profile in a targeted manner.

[Prediction of melting temperatures of wax gelators depending on their component composition].

The study of wax gelators is a new direction with the potential for use in foods for special dietary uses. Waxes of both plant and animal origin, which consist of various combinations of organic compounds: hydrocarbons, wax esters, free fatty acids and free higher alcohols, are among the studied ones. One of the main characteristics of these gelling agents is their melting point, which largely depends on the component composition of the wax. However, at present there are no models capable to reliably predict this parameter depending on the gel-forming agent composition. The aim of this work was to build models predicting the influence of wax composition on its melting temperature. Material and methods. Preparative flash chromatography was used to obtain individual fractions of the beeswax (obtained from a Russian apiary). On the basis of these fractions, combinations were made and their melting temperatures were measured using the method of differential scanning calorimetry. Two approaches were used to predict the melting temperatures of wax gel-formers: multiple linear regression and the construction of artificial neural networks. Results. A total of 68 gelling agent combinations were analyzed. The model obtained on the basis of multiple linear regression was characterized by high values of the multiple correlation coefficient (r2=0.77). Nevertheless, high values of the standard deviation in the most cases led to false prediction results. The application of artificial neural networks made it possible to get a more reliable prognosticating system with high values of the correlation coefficient (r2=0.97) and the standard deviation not exceeding 3 °Ð¡. Conclusion. As a result of the conducted work it has been shown that it is possible to predict melting temperatures on the basis of the component composition of gel-forming fractions. The use of the data obtained in the article will allow to develop oleogels with the specified composition and properties for their use in new types of foodstuffs.

[Investigation of the physiological and biochemical effectiveness of plasmalogens and astaxanthin in microencapsulated form].

Plasmalogens and astaxanthin have a wide range of biological effects, including pronounced antioxidant properties. One of the main disadvantages of using these biologically active lipids is their low stability, which leads to a decrease in biological activity in vivo. The aim of the work was the study of the physiological and biochemical effectiveness of plasmalogens and astaxanthin in microencapsulated form. Methods. The experiment was conducted using 70 male Wistar rats during 60 days. The first 28 days of the experiment animals received modified diet with lowered content of fat-soluble vitamins A, D, and E, via excluding fat-soluble vitamin mixture and sunflower oil from the diet. On the 29th day of the experiment, the animals were divided into groups. Standard fat-soluble vitamin mixture and sunflower oil were added into the diet of one group (K2 group), two other groups received emulsions, containing plasmalogens (0.80%), astaxanthin (0.04%) and fat-soluble vitamins in native (G3 group) or microcapsulated (G4 group) forms instead of sunflower oil (5.0% of the diet). During the next 32 days of the experiment, the animals' grip strength was measured; anxiety and motor activity were assessed in the elevated plus maze and open field tests; cognitive functions were assessed in the passive avoidance and Morris water maze tests. In the blood serum, the level of corticosterone, triglycerides, cholesterol, high-density lipoprotein (HDL), low-density lipoprotein (LDL), malone dialdehyde, hydroperoxides, and total antioxidant activity were determined. Results. A significant increase in the grip strength in animals treated with an emulsion with encapsulated plasmalogens and astaxanthin indicates animal endurance growth. In the Morris water maze test, animals of the same group showed the best learning ability, which indicates an improvement in cognitive functions. A significant more than 3-fold decrease in blood corticosterone level in the animals treated with plasmalogens and astaxanthin, regardless of the form of administration, in comparison with the indicator of animals in the control groups, indicates an adaptogenic effect and requires further study. The consumption of the emulsions led to a significant improvement in lipid metabolism: a significant decrease in serum cholesterol by 20% was shown, against the background of a significant reduction in LDL cholesterol by 25%. Conclusion. The beneficial effect of including the experimental emulsion in the diet is expressed in improving memory and cognitive functions, increasing muscle tone and the static component of endurance in male Wistar rats.

[Oleogels as prospective nutritional ingredients of lipid nature].

The composition of the lipid component of consumed foods affects the consumers' health. Fats are not only a source of essential fatty acids, but also participate in the formation of the organoleptic and rheological properties of foodstuffs. At the same time, fats are sources of saturated and trans-isomeric fatty acids, which excessive consumption is associated with the risk of cardiovascular diseases, and therefore, it is relevant to search for promising ways to replace such fats. The aim of this review is to summarize data from studies of oleogels as an alternative to such fats. Results. It has been shown that the prevalence of obesity in many countries, including Russia, remains an acute problem. At the same time, as a rule, in persons with obesity and cardiovascular diseases, the consumption of fat including saturated and trans-isomeric fatty acids is excessive. To reduce the content of saturated and trans-isomeric fatty acids in foodstuffs, such systems as oleogels have recently been considered. The interest in these systems is related to the fact that they can act not only as substitutes for solid fats - sources of trans- and saturated fats but also as carriers of biologically active substances. Conclusion. The results of the analytical study indicate that active research is currently underway concerning the properties of oleogels, their use in foodstuffs, and modeling the effect of consumption of oleogels and containing them foodstuffs on the general metabolic health of humans. These studies are currently in their initial stages, but their results already indicate the great potential of oleogels as a food ingredient.

[Impact of comorbid chronic heart failure with preserved left ventricular ejection fraction on the management of elderly cancer patients before and after total resections]. / Otsenka vliyaniya komorbidnoi khronicheskoi serdechnoi nedostatochnosti s sokhrannoi fraktsiei vybrosa levogo zheludochka na vedenie pozhilykh onkologicheskikh patsientov do i posle radikal'nykh operativnykh vmeshatel'stv.

OBJECTIVE: To determine the predictors of safe enhanced recovery after surgery in elderly cancer patients with comorbid chronic heart failure (CHF) and preserved left ventricular ejection fraction (LVEF). MATERIAL AND METHODS: There were 75 patients over 65 years old (mean 73.6±5.6 years) with cancer of abdominal and pelvic organs and comorbid cardiovascular diseases for the period from January 2018 to July 2020. All patients underwent total resections with enhanced postoperative recovery at the Petrovsky National Research Centre of Surgery. RESULTS: CHF with preserved LVEF was diagnosed in 42 (56%) patients (NYHA class I - 20 patients, class II - 19 patients, class III - 3 patients). ACE/ARA/neprilysin inhibitors were described in 74.7% of patients, beta-blockers - 70.7%, calcium channel blockers - 37.3%, diuretic therapy - 21.3%, antithrombotic therapy - 62.7%, statins - 54.7%, antiarrhythmic therapy - 12%. Preoperative correction of cardiac therapy was required in 60% of patients. Mean LVEF was 58.5±6.8%, pulmonary artery systolic pressure - 29±7.8 mm Hg, impairment of local myocardial contractility was observed in 6.7% of patients. Serum NT-proBNP level was 534.5±63.9 pg/ml, LDL-C - 3.3±1.1 mmol/l, GFR - 65.95±17.1 ml/min/1.73m2, glycated hemoglobin 6.37±0.67%. Perioperative risk of cardiovascular complications within 30-day postoperative period was assessed using the Revised Cardiac Risk Index (RCRI) score (6% in 59 patients, 10.1% in 11 patients, and 15% in 5 patients). Incidence of cardiovascular complications in early postoperative period was 4%, postoperative 30-day mortality rate - 1.3%. CONCLUSION: Our small study of surgical treatment of elderly cancer patients with comorbid CHF with preserved LVEF demonstrates the need for a personalized assessment of preoperative clinical and instrumental data to optimize cardiac therapy and perioperative monitoring. Multidisciplinary approach reduces perioperative mortality and cardiovascular morbidity from 7.2% to 4%.

[Metastasis of the right colon mucinous adenocarcinoma to aortocaval and retropancreatic space: case report and literature review]. / Metastaz slizeobrazuyushchei adenokartsinomy pravoi poloviny obodochnoi kishki v aortokaval'noe i retropankreaticheskoe prostranstvo: obzor literatury i redkoe klinicheskoe nablyudenie.

Metastases of the right colon cancer to extra-regional lymph nodes are rarely observed. Available literature data cannot be a reliable guide to choose the optimal treatment strategy. Indeed, excision of extra-regional lymph nodes is a rare experience and its results are poorly represented. According to our clinical experience, surgical intervention following comprehensive examination may be radical in patients with right colon cancer if distant metastases are absent. Resection of extra-regional lymph nodes can be safely performed in these cases. We report a patient with the right colon cancer and lesion of extra-regional lymph nodes behind the pancreatic head, paracaval and paraaortic space, hepatoduodenal ligament. Standard laparoscopic right-sided hemicolectomy with D-3 lymph node dissection was accompanied by resection of a conglomerate of nodal metastases behind the pancreatic head and superficial resection of the pancreas. Extra-regional lymph node excision is a reasonable option for colon mucinous adenocarcinoma stage I-III. However, comprehensive preoperative examination is required. Technical difficulty of extra-regional lymph node excision it is not the reason for limitation of surgical intervention. However, safe and total resection requires an adequate surgical approach.

Effect of Vanadium Complex with Enzymatic Hydrolysate of Soy Protein on Carbohydrate and Lipid Metabolism Disorders in Male Wistar Rats.

The effects of vanadium complex with enzymatic hydrolysate of soy protein (V-EHSPI) were studied in male Wistar rats with induced disorders of carbohydrate and lipid metabolism. The content of vanadium (IV) in the studied complex was 15.8 mg/g dry product. High-lipid high-carbohydrate diet was used to induce disorders of lipid and carbohydrate metabolism. Addition of vanadium in three different doses to the diet over 100-day experiment reduced body weight gain and the levels of glucose, insulin, leptin, and triglycerides. V-EHSPI produced beneficial effects on carbohydrate and lipid metabolism even in a dose 5 µg/kg body weight/day (calculated from the mean food consumption over the entire treatment period). Significant inhibition of growth and changes in the weight of organs in animals treated with V-EHSPI attested to toxicity of vanadium in the studied dose range.

[A comparative evaluation of the effect of soy protein and its enzymatic hydrolysate on lipid metabolism in male Wistar rats with induced obesity].

Among various food proteins, soybean proteins have the greatest traditions of application for the dietary correction and prevention of lipid metabolism disorders and related complications. Aim. In an in vivo experiment using male Wistar rats, the lipid-lowering properties of soy protein and its enzymatic hydrolysate were tested to evaluate their possible use as ingredients of specialized foods. Material and methods. Animals were randomly divided into 3 groups: control group G1 and 2 experimental groups G2 and G3. The total duration of the experiment was 70 days. The animals of the control group G1 were fed with high-lipid semi-synthetic diet. Animals of the experimental groups G2 and G3 received the same high-fat semi-synthetic diet, but with a 50% replacement of casein with soy protein isolate (SPI) and enzymatic hydrolyzate of SPI (EHSPI), respectively. The blood glucose was measured once per 2 weeks. At the end of the experiment on the 71st day the level of glycated hemoglobin was determined in the blood; the levels of triglycerides, cholesterol, high density lipoproteins (HDL), low density lipoproteins (LDL) and the concentration of malon dialdehyde were determined in the serum. Results and discussion. Starting from the 6th week of the experiment and prior to its completion, the average food intake of animals from the G3 group was significantly (р<0.05) lower compared to animals of the G1 control group. The food intake of animals of group G2 was significantly (р<0.05) reduced compared with this indicator for animals of group G1, starting from the week 8 of the experiment and prior to its completion. The monitoring of the body weight gain did not reveal significant differences between all groups of animals, despite differences in the food intake. Replacing casein in the diet by 50% with SPI had a pronounced antioxidant and cholesterol-lowering effect. The total cholesterol content (1.65±0.05 mmol/l) decreased significantly (р<0.05) due to a decrease in LDL (0.90±0.03 mmol/l), and malon dialdehyde level lowered (3.7±0.5 µmol/l, р<0.05) in the serum of group G2 rats compared with animals of the control group G1 (2.01±0.13 and 1.12±0.09 mmol/l; 5.1±0.4 µmol/l, respectively). Replacing casein by 50% with EHSPI in the diet of G3 rats was unfavorable, significantly (р<0.05) increasing the level of total cholesterol (2.76±0.16 mmol/l) and cholesterol in LDL (1.66±0.12 mmol/l) in blood of these animals compared with animals of both comparison groups G1 and G2. Conclusion. A preclinical comparative study of the cholesterol-lowering and antioxidant properties of the SPI substantiates the prospect of its following clinical trials with the aim of including into the composition of specialized foods for prevention and diet therapy of the disorders of endogenous cholesterol homeostasis.

[Effect of specialized product with modified carbohydrate profile on clinical and metabolic parameters in patients with type 2 diabetes].

The prevalence of type 2 diabetes mellitus (DM2) determines the need to develop evidence-based methods for preventing this disease, including personalized approaches to the dietary correction of metabolic disorders in DM2, including the use of specialized foods. Aim. To evaluate the effect of a low-calorie diet with the inclusion of a specialized product (SP) with a modified carbohydrate profile (dry instant mixture) on the glycemic and metabolic control indicators in patients with DM2. Material and methods. The study included 30 patients with DM2 with concomitant obesity, grade I-III, who were on oral sugar-lowering therapy. Within 2 weeks, patients of the main group received a low- calorie diet (1550 kcal/day) with the inclusion of SP with a modified carbohydrate profile (based on maltitol and with sweeteners) with strawberry flavor in the form of a drink (30 g dry mix per 150 ml of water) for the second breakfast instead of a carbohydrate-containing dish, which provided the intake of 7.8 g of protein, 6.1 g of fat, 1.8 g of carbohydrates, 5.6 g of maltitol. The comparison group received a low-calorie diet (1550 kcal/day) without the inclusion of SP. In all patients, on the background of complex therapy, anthropometric indices, body composition, parameters of carbohydrate, lipid and protein metabolism, liver function, and lipid peroxidation were assessed. Results and discussion. It was shown that SP inclusion into the hypocaloric diet was accompanied by a significant decrease in the level of basal glycemia by an average of 17.4% from the initial level (p<0.05), serum total cholesterol (TC) and low density lipoproteins cholesterol (LDL-C) on average by 26.9 and 36.2% of baseline, respectively, p<0.05, while in patients of the comparison group, the change in fasting blood glucose was not statistically significant (a decrease of 8.1%), and the decrease in TC and LDL-C was on average 22.1 and 21.0%, respectively (p<0.05). At the same time, against the background of complex therapy, positive dynamic in lipid peroxidation in the main group was observed: the level of blood serum malondialdehyde decreased on average by 25.3% from the baseline values (p<0.05). Conclusion. The inclusion of SP with a modified carbohydrate profile in a low-calorie diet is accompanied by an improvement in glycemic control, lipid metabolism and antioxidant status of patients with DM2, helping to reduce the risk of developing systemic vascular complications in this disease.

[Successful surgical treatment of aortic heart disease as a complication after combined targeted therapy for cancer]. / Khirurgicheskoe lechenie aortal'nogo poroka serdtsa kak oslozhneniia posle kombinirovannoi targetnoi terapii raka.

Cardiovascular diseases and malignancies are leading causes of mortality in the world. Two categories of advanced age patients with cancer are observed in clinical practice. These are patients with cardiovascular diseases as comorbidities and patients with cardiovascular diseases as a complications of targeted therapy for cancer. Cardiac toxicity of chemotherapeutic drugs results myocardial dysfunction, occurrence or progression of heart valve disease, coronary artery disease, arterial hypertension and thromboembolism. A patient who underwent aortic valve replacement and coronary artery bypass surgery is discussed in the article. Aortic valve disease and coronary artery disease were complications of targeted radio- and chemotherapy for sigmoid colon cancer followed by lung and liver metastases. Questions of timely diagnosis and treatment of advanced age patients in multi-field surgical clinic are also analyzed.

[The experimental evaluation in vivo of hypoglycemic properties of functional food ingredient - polyphenolic food matrix].

The aim of this study was the evaluation of hypoglycemic action of functional food ingredient (FFI) - a polyphenol food matrix in 3-month in vivo experiment with the use of fat male mice C57BL/6. The food matrix was produced by means of incubation of bilberry leaves extract (2% solution, pH 3.6) with buckwheat flour in ratio 1:50 during 45 min at 25 °C. The polyphenol content in experimental batch of matrix was 26.6±0.5 mg-equivalent of gallic acid per 1 g of flour. The experiment was conducted with the use of 46 male mice C57Bl/6c. Blood glucose level was estimated before starting the feeding experiment. An oral fasting glucose tolerance test (GTT) was also conducted, the area under the curve (AUC) was calculated. The animals were randomly divided into 4 groups (according to the body weight, glucose level and AUC): control group K1, fed with standard semisynthetic diet, control group K2 (n=10) and experimental groups G3 and G4 (n=13). The symptoms of type 2 diabetes in groups K2, G3 and G4 were modeled with the use of high-fat high-carbohydrate diet (HFHC diet, 30% fat, 20% sucrose). FFI was included into the diet of animals of experimental groups G3 and G4 in doses 2.5 and 5 g per 100 g of ration, respectively. The GTT test was repeated on the 40th and 82nd days of experiment. On the 15th, 54th and 91st days the insulin resistance test (IRT) was conducted. The consumption of HFHC diet by K2 group animals resulted in development of obesity in these animals to the week 11, which was characterized by increase in the body weight gain (37.1±4.9%) in comparison with control group K1 animals (23.4±2.2%). The introduction of FFI into animal's diet decreased significantly body weight gain of these animals in comparison with K2 group. On the week 8, the significant increase in blood glucose level of animals fed with HFHC diet was found (K2 - 8.2±0.3, G3 - 8.1±0.3, G4 - 8.5±0.3 mmol/L), in comparison with control group K1 (7.1±0.3 mmol/L). On the 91st day of experiment this difference remained significant only for group K2 (9.3±0.6 against K1 group - 7.7±0.3 mmol/L), what shows the beneficial hypoglycemic action of the FFI in both doses (for G3 group - 8.5±0.2, for G4 - 8.4±0.3 mmol/L). On the week 8 the disorder in glucose tolerance was found in animals of group K2, what is one of type 2 diabetes symptoms. The introduction of FFI in a dose 2.5 g/100 g into group G3 diet inhibited the development of these disease symptoms. The introduction of FFI in a higher dose (5 g/100 g of a diet) to a certain extent inhibited the development of insulin resistance. There was no effect of FFI, introduced into animal's diet, on cognitive functions and short-term and long-term memory.

THE PURPOSE OF THE STUDY: Improving the treatment of advanced peritonitis via use in therapy antihypoxant Reamberin and hepatoprotector Remaxol, nutritional support, sanitation laparoscopic abdominal cavity. SUBJECTS: A total of 232 children aged 1 to 15 years with generalized purulent peritonitis treated at the children's surgical departments of Samara from 2001 to 2014. A study group comprised 148 patients who used the optimized pathogenetic therapy. In the study group was allocated two groups: 64 patients in the pathogenetic therapy that used antihypoxant reamberin, and 84 children in the treatment of which reamberin and hepatoprotector remaxol. All the children of the main group received nutritional support (trophic feedings), used in the surgical treatment of abdominal laparoscopic sanitation. Comprehensive survey includes the study of the dynamics of the level of white blood cells, leukocyte index on Kalf-Caliph, erythrocyte sedimentation rate, temperature, total albumin concentration, transaminase levels. RESULTS: Comparison of the studied parameters in the study and control groups, showed a more rapid decrease in the symptoms and signs of intoxication (leukocytosis, LII, body temperature), relief of enteric disease, recovery of protein-synthetic function of the liver, a decrease of cytolytic and mesenchymal-inflammatory syndrome in the study group, especially in the subgroup in which therapy was included remaxol. CONCLUSIONS: Optimization of treatment involving the application of the combined drugs--antihypoxant reamberin, hepatoprotector remaxol, nutritional support and implementation of laparoscopic abdominal sanitation led to improved results of therapy common purulent peritonitis in children.

The study of the antimicrobial activity of colloidal solutions of silver nanoparticles prepared using food stabilizers.

The bactericidal effect of colloidal solutions of silver nanoparticles based on food stabilizers, gum arabic and chitosan, against bacterial cultures of microorganisms in food production is described. The antibacterial activity of nanotechnology products containing different amounts of stabilizing additives when applied to solid pH-neutral substrates is studied. For its evaluation a method making it possible to take into account the capability of nanoparticles to diffuse in solid media was applied. Minimal inhibitory concentrations of nanoparticles used against Erwinia herbicola, Pseudomonas fluorescens, Bacillus subtilis, Sarcina flava were found. A suggestion was made concerning the influence of the spatial structure of bacteria on the antibacterial activity of colloidal solutions of silver nanoparticles. The data concerning the antibacterial activity and minimal inhibiting concentrations of nanoparticles may be used for development of products suppressing activity of microorganisms hazardous for food production.
