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.

AbstractIntroduction: In recent years, researchers have paid attention to the biological active products fromraw materials of animal origin. Lyophilized bovine bile and bovine liver hydrolyze and varieties ofplants have been used for increase secretion of bile in traditional systems of medicine of variouscountries. We investigated that beneficial effects of new product particularly its treatment liverdamage, improve regeneration process of damaged liver cell, effects on bile secretion, bile bilirubin,and bile cholesterol and plasma cholesterol levels. Moreover, we investigate physical, chemicalcapacity and drafted a MNS document.Goal: To complete pharmacological, technological and standardization study of Sillichol biologicalactive product.Material and MethodsSeveral biochemical methods were used for determination of chemical compounds in liverhydrolysate and lyophilized bile. The product was formed in combined powder form by dried stirringmethod and it was capsuled by NJP-1200 capsule machine. Litchfield-Wilcoxon’s method was usedto study the acute toxicity effect. The median lethal dose (LD50) value was calculated using themethod of Pearson and toxicity level of was determined according to classification of Sidorov K.K(1973). Human equivalent dose (effective dose) was calculated with according to FDA guidancefor drug-dose conversion. Acute hepatitis – Carbon tetrachloride (CCl4) induced liver damage inrats (Skakun et al, 1984); Bile secretion effect was determined by method of Rozuet Jousse, 1980.All value expressed as mean S.E obtained from n number of experiments. The Student’s t-testfor unpaired observation between control and experimental samples was carried out for statisticalevaluation of a difference; p values of 0.05 or less were considered as statistically significant.ResultsTotal nitrogen, amino nitrogen, fat, ash and solution index were measured in liver hydrolysate.The results were accepted standard requirements of MNS 6484:2014. Bovine bile was dried byLabconco freezone L12 freeze drier in Drug Research Institute. The product named Sillichol wasformed combined powder form and capsuled №0 capsule. From the result of preclinical study, ourinvestigational new product is included in practically non-toxic class according to toxicity classificationby Sidorov (1750 mg/kg). Sillichol biological active product was increase bile level which is producedin liver cells and decreased bile cholesterol levels by 2.3-8.0% in the test group compared with thecontrol and reference groups.Conclusion: The biological active product was improving regeneration process of liver cells,normalize cell structure, effect to the anti-inflammatory in damaged liver cells.

BACKGROUND. Caseinophosphopeptides (CPPs) were released during in vivo digestion process under the influence of the gut proteolytic enzymes. CPPs contain some phosphorylated serine residues which are able to connect calcium ions. This can predict the bone development and osteoporosis prevention effects of CPPs.
MATERIAL AND METHODS. In our study we have used acid caseins, from cow and camel milk, which were then hydrolysed using pancreatin preparation in vitro.
RESULTS. The AN/TN rate of resulting hydrolysates were 3.8 and 3.2, subsequently. Then CPPs were precipitated by adding calcium chloride and ethanol and the yield of both types of CPPs was the same (16%). The ratio Ca:P were 2.8:1 and 2.7:1 for cow and camel peptide preparations, subsequently.
СONCLUSION. These results show the real potential for obtaining calcium substance on the base of CPPs.
