RESUMO
AIM OF STUDY: to evaluate the efficacy and tolerability of meat-containing canned food for enteral nutrition in clinical settings in patients with gastrectomy. The product was made from animal protein (beef) with the addition of vegetable oils, soy protein, maltodextrin, stabilizer, vitamins and minerals. 40 patients with gastrectomy were included to the study and randomly formed 2 groups of 20 persons: the main group (8 men and 12 women, mean age 64.4±12.4 years) on the background of standard mashed diet for 14 days received 2 portions of the tested product (240 ml), the control group (5 men and 15 women, mean age 64.8±12.9 years) was treated with standard diet. Daily registration of the symptoms was carried out filling the 5-point scale of the Likert (the presence and severity of abdominal pain, flatulence, heartburn, nausea, a feeling of heaviness after eating, incomplete evacuation of the intestine). The Bristol stool scale was used to assess the dynamics of the stool. Laboratory parameters (hemoglobin, blood serum level of total protein, albumin and iron) and body composition parameters were evaluated before and after treatment. Consumption of meat-containing canned food for enteral nutrition was accompanied by significant decrease in the severity of nausea (from 1.20±0.29 to 1.02±0.05 points of the Likert scale, p=0.017), a decrease in abdomen heaviness (from 1.8±0.8 to 1.4±0.6 points, p<0.05), contributed to an improvement in stool consistency, an increase in all body composition parameters, a positive dynamic of protein metabolism (increase of hemoglobin level from 119.2±9.6 to 122.6±6.8 g/l, p>0.05, blood serum protein and albumin). A tendency to increase the mental component of the quality of life (+4.2%) was found. Thus, meat-containing canned foods for enteral nutrition can be used in the diet of patients in the postoperative period, they are well tolerated in conditions with loss of appetite, are effective in patients with protein-energy malnutrition.
RESUMO
The paper presents the results of the study on the influence of water with a reduced deuterium content and the meat semi-prepared foods produced with its addition on the indicators of the laboratory animals with the model of alloxan diabetes. The effect of low concentrations of deuterium on the body weight dynamics was shown as well as the manifestation of glucosuria and ketonuria, and clinico-biological indicators of the animal's blood. The experiment was carried out during 42 days on male rats of Wistar stock, which were divided into 4 groups - 2 experimental, control (n=10) and intact (n=6), and consisted of three stages: adaptational, the stage of modeling of alloxan diabetes (a single intraperitoneal injection of alloxan monohydrate - 12 mg/100 g body weight) and dietic therapeutic. The animals of the experimental groups consumed water with a reduced deuterium content and standard vivarium diet or the meat minced semi-prepared products produced with its addition and cooked to culinary readiness. The control group consumed tap water and standard vivarium diet. In animals of the 1st group, which consumed the meat product, glucosuria persisted up to the 28th day (the 11th day after administration of alloxan), ketonuria up to the 34th day (the 17th day after modeling). In rats of the 2nd group, which consumed water with the decreased deuterium content, glucose in urea was not detected already on the 7th day after administration of alloxan, ketones on the 17th day after modeling of the disease, respectively. In animals of the control group, glucosuria and ketonuria persisted up to the end of the experiment. As a result of the investigations, the positive effect of water with a reduced deuterium content and the meat food produced with its use was established. It was manifested in a decrease of glucose level in the urea of the animals from the experimental groups compared to the control group on the 5th day of disease modeling and normalization on the 17th day of modeling. This experimentally demonstrated the possibility to use deuterium-depleted water in a meat product composition intended for nutrition of people with an impairment of carbohydrate metabolism for correction of metabolic processes.
