Spent brewer’s yeast Saccharomyces cerevisiae was hydrolysed using bovine pancreatictissue as an enzyme source. The resulting hydrolysate contains 4.7% amino nitrogenand the ratio Namin/Ntot was determined as 0.6. Moreover, other physico-chemicalparameters of the hydrolysate were also comparable with the same products on foreignmarkets. Toxicity of hydrolysate is low (LD50 2,5 g/kg), microbiological and heavy metalcontamination were in required range. The IC50 value of obtained yeast hydrolysate’santioxidative activity according to the DPPH assay was 1.6±0.5 mg/ml, while IC¬50 ofthe yeast hydrolysate rich in Cyclo-His-Pro evaluated as 1.9 mg/mL.

BackgroundLiver protecting effect of liver hydrolysate is studied on CCl4 induced by acute toxic hepatitis on rats compared with “Raw Liver Glandular” which is similar product of “Swanson”, USA. Result was confirmed with histological study.Materials and MethodsCarbon tetrachloride-CCl4 is considered as a direct hepatotoxin which produces centri-lobular necrosis and steatosis. The mechanism of acute toxic hepatitis induced by CCl4 involves lipid peroxidation of membrane bound fatty acids which result in destructing the cell membrane and the intracellular organells of the hepatocyte.Result:As study result, after 7 days CCL4 exposure, experimental group’s serum ALAT (p<0.01), GGT (p<0.05) and ALP (p<0.05) levels decreased rapidly compared with control groups.ConclusionAlthough, liver hydrolysate is not medicine for treatment liver damage, it might be improved regeneration process in the damaged liver cells. As result, histomorphological study came to the following conclusion: in the seventh day of the model of acute toxic hepatitis of the liver in rats, cytoplasm vacuoles of hepatocytes were decreased sharply, hepatocytes became multilateral, “Kupffer cells” were increased, young hepatocytes were streamlined as columnar-cells, capillaries were became visible and was began regeneration. There were reported that bovine and pork protein hydrolysate contains essential amino acids with antioxidant effect which prevents liver cells from oxidative stress. Besides it, liver hydrolysate containing amino acids, vitamin B1, B6, folic acid and some minerals improves metabolism and regeneration process of damaged liver cells.

Objective:
To retrospectively analyze the drug resistant characteristics and distribution of multi-drug resistant bacteria infection in State Second General Hospital.
Methods:
Total 772 cases treated in our hospital from January 2017 to September 2019 were selected as subjects. The automatic microorganism analyzer VITEC-2 and manual method were used for bacterial identification; Kirby-Bauer disk diffusion method was used for susceptibility test; WHONET 5.6.2019 software and EXCEL 2013 were used to analyze the distribution and drug sensitivity of isolated bacteria.
Results:
Among the 772 strains of multi drug resistant bacteria, the proportion of Gram-negative bacteria was 84.9%, and the proportion of Gram-positive bacteria was 15,1%; fluconazole resistant candida accounted for 3.2%. Multi -drug resistant bacteria mostly distributed in sputum, accounting for 23.5%; 50.5% multi-drug resistant strains were from intensive care unit.
Resistant rates of Escherichia Coli ESBL, Klebsiella ESBL and Enterobacter spp to cephalosporins and penicillin were 100%. Resistant rates of staphylococcus aureus to antibacterial agents; cephalosporins and penicillin were 100%.
Conclusion
Gram-negative bacteria were the main multi-drug resistant bacteria of our study in our hospital, mainly distributing in Intensive care unit patients. They are highly resistant to most antibacterial agents, which provides a theoretical basis for the prevention and control of multi-drug resistant bacteria infection in hospital.

Introduction:
Rongalite have many names, the trade name for sodium hydroxymethylsulfinate also sodium formaldehydesulfoxylate. It causes serious side effects to human body and is forbidden to be used as food additives by law. It is still frequently used illegally in rice and flour products. Based on this study, we determination rongalite level in some friut widespread of in our country. The study was done materials used in Lingonberry, Blueberry, Hippophae, Blackcurrant fruits collected in Khuvsgul. To determine rongalite was followed by protocol to sanitation-laboratory of food of the school of social of health in MNUMS used for NC-860 Universal Food Safety Analyzer. The concentration in sample that were measure to 153.88- 213.85 mg/kg of Lingonberry, Blueberry, Hippophae, Blackcurrant fruits weight.
Materials and methods :
The study was done materials used in a Lingonberry, Blueberry, Hippophae, Blackcurrant fruits collected in Khuvsgul. To determine rongalite was followed by protocol to sanitation-laboratory of food of the school of social of health in MNUMS used for NC-860 Universal Food Safety Analyzer. Weigh accurately 5.0 g of the fruit in a plastic extract bottle, add 20 ml of distilled water, extract for 10 min by centrifugated. Than filtrate into 6 time respectively test tubes through 0.45 μm membrane using remove the color. Rongalite determined in use a disposable test tube, add 1 drop of oxidizing reagent. Amount of rongalite used for NC-860 Universal Food Safety Analyzer.
Result and discussion
Based on the obtained result, the maximum concentration observed in Blueberry was 213.85 mg/kg, and the minimum concentration observed in Hippophae was 153.88 mg/kg, the concentration observed in Lingonberry was 192.8 mg/kg, the concentration observed in Blackcurrant was 155.29 mg/kg of contained weight respectively. The difference of rongalite concentrations in wheat powder and rice powder was 0.41 mg/kg in China. Identified to the result was higher than other research.
