Food Consumption and Metabolic Risks in Young University Students

The purpose of this study was to analyze the association between components of the diet, metabolic risks, and the serum concentrations of adiponectin and interleukin-6 (IL-6). With prior informed consent, an analytical cross-sectional study was carried out with 72 students in their first year of university. The subjects had a mean age of 19.2 ± 1.0 years and body mass index of 23.38 ± 4.2, and they were mainly women (80.6%). Sociodemographic, anthropometric, and dietary data and metabolic risk factors were evaluated, and biochemical parameters and adipocytokines were also considered. The data were analyzed using means, ranges, and correlations, as well as principal components. In general, the protein, fat, and sodium intake were higher than the international dietary recommendations, and deficiencies in vitamins B5 and E, potassium, phosphorus, selenium, and zinc were observed. The most frequently observed metabolic risks were insulin resistance and hypoalphalipoproteinemia. IL-6 was positively correlated with lipid and protein intake. Adiponectin showed a positive correlation with high-density lipoprotein and a negative correlation with insulin, weight, and waist, while the adiponectin pattern was similar to that of vitamins E and A, which decreased with increasing intake of calories, macronutrients, and sodium. In general, a hypercaloric diet that was high in protein, fat, and sodium and deficient in vitamins, mainly fat-soluble, was associated with a lower concentration of adiponectin and a higher concentration of IL-6, which favor the presence of metabolic risks, including insulin resistance. Intervention studies are required to evaluate the dietary intake of metabolic markers in young people without comorbidities, which will lay the foundation for implementing prevention strategies.

Therapeutic efficacy of a complex drug based on interferons for Actinobacillus pleuropneumonia in piglets

The article presents the results of studying the therapeutic efficacy of the complex drug tsipropig based on recombinant porcine interferons for Actinobacillus pleuropneumonia of piglets at an industrial pig-breeding complex and its effect on nonspecific immunity. It has been found that the drug has pronounced therapeutic properties and an immunomodulatory effect due to the presence of the fluoroquinolone antibiotic ciprofloxacin in the composition of tsipropig, the immunocorrective activity of its constituent recombinant porcine interferons alpha and gamma and vitamins E and A possessing antioxidant properties.

Effect of supplementation of several coated vitamins and chelated trace minerals on reducing the incidences of subclinical mastitis in crossbred cows

Two hundred and fifty five crossbred cows were selected, having a history of sub-clinical mastitis (SCM) and clinical mastitis (CM) in previous lactation. Seventy eight crossbred cows were served as control, and the remaining were fed daily 10 g supplement containing chelated Cu, Zn, Cr, vitamins E and A along with iodine for 4 weeks prior to calving. Milk and blood samples were collected for analysis of SCC, Na, K, Cl, pH, EC, neutrophil count, FRAP activity etc. Out of 177 experimental cows, only 36 (20%) showed signs of SCM and CM with Mastect strip and CMT which was confirmed by SCC in milk (average 7.26x105 cells/ml milk). However, 67 animals (86%) out of 78 in control group were affected by SCM as indicated by the higher SCC in milk (average 10.11x105 cells/ml milk), which was later aggravated to CM. Milk pH, EC, Na and Cl content in milk were higher (P is less than 0.05) in animals affected by SCM than the normal animals. In experimental group, of 141 animals SCC was within the normal range (1.22-2.36x105 cells/ml milk) and no signs of SCM or CM were observed. Milk lactose, protein, SNF and FRAP activity were higher in unaffected as compared to mastitic animals. On supplementation of vitamins and chelated minerals, blood neutrophil count decreased, whereas, immunoglobulin and FRAP activity increased significantly (P is less than 0.05). It was found that feeding vitamins and chelated minerals based supplement during pre-partum period could significantly reduce the incidences of SCM and CM in crossbred cows.

Metabolic state of perifocal zone and resection line of skin melanoma.

e19049 Background: The state of metabolism in perifocal zone and morphologically intact skin along resection line is of importance for the processes of neoplasm metastasizing and relapse, including skin melanoma. Normalization of the state of free-radical processes, first of all along resection line, and then in neoplasm perifocal zone, should be a characteristic of pathogenically substantiated neoadjuvant influence. Methods: to study activity of free-radical processes in tissue of skin melanoma relapse, its perifocal zone (PZ) (1 cm from tumour edge) and in skin along resection line (3-5 cm from tumour edge) we investigated concentration of vitamins E and A, activity of superoxide dismutase (SOD), catalase, summary peroxidase activity (SPA), and malonic dialdehyde level (MDA) in patients with skin melanoma (pT2-3N1-2M0). The study group included 54 samples after treatment (chemotherapy and radiation). Control groups: 45 samples before treatment (CG1) and 27 samples of intact skin after plastic operations (CG2). Results: After treatment MDA concentration in tumour tissue increased by 33.4% in comparison with the CG1, but remained 17.7% lower than in CG2. Average increase in concentration of vitamins E and A was equal to 1.8 times, catalase activity decreased by 30.3% in comparison with parameters before treatment (p<0.05). SOD/catalase coefficient was 1.3 times higher than in the CG1, but 3.4 times lower than CG2.More manifested changes in activity of free-radical processes were observed in PZ: MDA concentration level after treatment increased by 30% in comparison with the CG1, and differed from the one in CG2 only by 10% (p<0.05). Catalase activity decreased by 1.5 times and didn’t significantly differ from the corresponding parameter in tumour tissue after treatment. Normalization of concentration level of vitamins A and E without change of their ratio was observed. There was 1.6-fold increase of SOD/SPA coefficient in comparison with the CG1, however it was 2.4 times lower than CG2 (p<0.05). All parameters under study along resection line after treatment didn’t significantly differ from parameters in CG2. Conclusions: The performed treatment completely restores broken metabolism in skin along resection line, partially–in tumour perifocal zone.
