Introduction. Underground mining of chrome ores is characterized by constant exposure to chemical factors on production workers, leading to changes in critical organs and systems. The aim of the work was to study changes in some biochemical parameters in workers engaged in underground mining of chrome ores. Materials and methods included assessing the chromium content in the air of the working area and biological media of workers, the study of many biochemical parameters and protein fractions of blood serum, modelling of cause-and-effect relationships. Results. The workers of the observation group compared to the comparison group showed a significant (up to 1.5 times) increase in the level of chromium in the blood and urine, an increase in the level of IgE specific to chromium - up to 1.6 times, the activity of ALAT and γ-HT in the blood serum - up to 1.3 times, the level β2-microglobulins in serum and urine - up to 1.6 times, serum creatinine levels, slowing of GFR, increased serum AOA, β-globulins and γ-globulins levels. Conclusion. The constant presence of chromium compounds in the air of the working area of mineworkers leads to an elevated concentration of chromium in the blood and its excretion in the urine. The workers of the studied production showed an increase in the level of many laboratory indicators of adverse effects on the liver and kidneys, the immune and antioxidant systems. Changes in the protein fractions of blood serum were revealed in workers at the mine mining chromium ores.

AbstractSerum protein levels are related to physiological and pathological status of animals and could be affected by both genetic and environmental factors. This study aimed to evaluate genetic variation of serum protein profile in sheep. Blood samples were randomly collected from 96 Lori-Bakhtiari ewes, a heavy meat-type breed. Total protein, albumin, globulin, α1, α2, β and γ globulins and IgG levels were measured in blood serum. The samples were genotyped using the Illumina OvineSNP50 BeadChip. The studied traits adjusted for age, birth type, birth season and estimate of breeding value for body weight were considered as pseudo-phenotypes in genome-wide association analysis. In the GWAS model, the first five principal components were fitted as covariates to correct the biases due to possible population stratification. The Plink, R and GCTA software were used for genome-wide association analysis, construction of Q-Q and Manhattan plots and estimation of genetic variances, respectively. Noticeable genomic heritabilities ± SE were estimated for total and γ globulins (0.868 ± 0.262 and 0.831 ± 0.364, respectively), but other protein fractions had zero or close to zero estimates. Based on the Bonferroni adjusted p values, four QTLs located on 181.7 Mbp of OAR3, 107.7 Mbp of OAR4, 86.3 Mbp of OAR7 and 83.0 Mbp of OAR8 were significantly associated with α1, β, β and γ globulins, respectively. The results showed that the PKP2, IGF2R, SLC22A1 and SLC22A2 genes could be considered as candidate genes for blood serum proteins. The present study showed significant genetic variations of some blood protein fractions.

The aim of the study was to compare contents of individual protein fractions determined by electrophoresis in blood serum of healthy periparturient goats. Eight clinically healthy white shorthaired goats were examined. Blood samples of these goats were taken from v. jugularis three weeks and two weeks before the anticipated parturition, on the parturition day, 7 days after the parturition, and 28 days after the parturition. Individual protein fractions, albumins, α1-, α2-, β1-, β2- and γ-globulins were identified by electrophoretic analysis of blood serum. Percentage shares of individual protein fractions were converted from total protein values to g·l-1 values. The results indicated that individual serum protein fractions in periparturient goats showed significant dynamics of change. There were no significant differences between samples taken before the parturition and on the parturition day (except for the increase of β2 from 2.5 ± 0.3 g·l-1 observed 3 weeks before the parturition to 3.2 ± 0.4 g·l-1 measured 2 weeks before the parturition, and the decrease of γG levels from 9.5 ± 2.6 g·l-1 observed three weeks before the parturition to 8.1 ± 1.7 g·l-1 found on the parturition day), yet most indicators measured after the parturition were significantly higher (p < 0.05) than on the parturition day (values in g·l-1 observed on the parturition day versus values measured 28 days after the parturition: total protein 60.6 ± 4.3 vs. 71.3 ± 2.4, albumins 37.4 ± 2.9 vs. 42.7 ± 1.0, α2 3.4 ± 0.5 vs. 4.1 ± 0.8, β1 5.6 ± 0.5 vs. 6.3 ± 0.9, γG 8.1 ± 1.7 vs. 12.3 ± 1.9). The results bring new knowledge on the values of individual fractions of serum proteins in healthy goats, which is necessary for diagnostic interpretation of pathological findings in animals and also for experimental studies.

Introduction. The health of workers is determined by both social and individual, as well as production factors, including noise, vibration and dust, characteristic of technological processes in mining enterprises. Industrial noise above 90 dBA and dust in the form of suspended and fine particles causes dysfunction of the cardiovascular system and respiratory organs.The aim of the study is to assess the impact of harmful physical factors and industrial dust on changes in some biochemical and functional indicators of the cardiovascular system and respiratory system of employees of the enterprise for underground mining of ore.Materials and methods. The assessment of working conditions of workers engaged in underground mining and processing of chrome ores, the analysis of industrial dust on the dimension and quantitative content of fine particles PM10 and PM2. 5, the study of biochemical parameters of lipid metabolism, oxidant and antioxidant systems, indicators of respiratory function. Results. Harmful working conditions (class 3.1–3.4) in terms of noise and vibration were revealed at the workplaces of employees of the main specialties observation group. In the air of the working zone, the highest content of fine particles PM2.5 (2.68±0.54 mg/m3) and PM10 (4.64±0.93 mg/m3) was established at the site of drilling operations and cleaning of the bottom-hole space. Deviations of biochemical parameters characterizing intensification of free radical processes and antioxidant protection, imbalance of lipid spectrum parameters, and violation of functional parameters of external respiration were revealed. A high degree of connection with the working conditions of the frequency of increased levels of lipid hydroperoxide and antioxidant activity (EF=60.71–65.84%) was established.Conclusions. In high noise level (more than 94 dBA), general and local vibration (more than 116 and 127 dB respectively) and the content of fine particles PM2. 5 (more of 2.14 mg/m3) and PM10 (over of 3.71 mg/m3) at underground mining of chrome ore workers have identified abnormalities in the form of increase 1.6 times the level of lipid hydroperoxides and total antioxidant activity, reducing to 1.2 times the level of high density lipoprotein, improving 1.2–1.3 times of low-density lipoproteins, triglycerides, and atherogenic index in blood serum, peak expiratory flow. A high degree of professional conditioning have the frequency of increasing the level of lipid hydroperoxide in blood serum and antioxidant activity of blood plasma.

Introduction. The overwhelming number of publications contains only data on the content of individual antioxidants, but not on the overall antioxidant activity of the blood in patients with vibration disease.The aim of the study was to determine the total antioxidant activity of blood serum in patients with vibration disease.Materials and methods. Th e main group consisted of 30 people diagnosed with “Vibration disease” of 1 degree (n=21) and 2 degrees (n=9). Th e control group consisted of 30 clinically healthy men, comparable in age with the main group (p=0.66). Th e total activity of antioxidant systems of blood plasma was evaluated photometrically using the test system “Total antioxidant status-Novo” (“Vector-best”, Russia).Results. The indicator of the total antioxidant status (TAS) was 1,038±0.232 mmol/l in the examined main group, against 1,456±0.225 mmol/l in the examined control group (p<0.000001). Th e coefficient of variation (CV) in patients with vibration disease was 22.35%, 1.45 times higher than in the control group (15.45%). In the main group there was a positive correlation between age and TAS (R=0.525), in the control group there was no such relationship (R=0.095). Th e degree of decrease depended on the severity of vibration disease.Conclusions. 1. The development of vibration disease is accompanied by a decrease in the antioxidant status of blood serum. 2. Th e degree of decrease in the antioxidant status of blood serum correlates with the severity of vibration disease. 3. Reduction of TAS can serve as a pathogenetic justification of the need to include drugs and/or biologically active additives with antioxidant activity in therapy

Two experiments were conducted with fatteners (♀ (Landrace × Yorkshire) × ♂ duroc), 50 animals each (10 pigs per group). The fatteners from the control group (C) were administered feed mixtures with genetically modified soybean meal (SBM-GM) used as the only protein source; whereas these from experimental groups (E1–E4) received feed mixtures in which the SBM-GM was replaced with increasing amounts of raw seeds of pea (Experiment I) or blue lupin (Experiment II): E1—5.0%, E2—10.0%, E3—15.0%, and E4—17.5%. Once the fattening period was completed, production results were determined, and selected blood serum indices were assayed to establish the effect of the nutritional factor on body homeostasis and health status of the animals. Pigs from all groups revealed a similar growth rate and meatiness (p > 0.05). In Experiment I serum analyses showed lower (p < 0.001) concentrations of: cholesterol in E1, E3 and E4; creatinine in E1 and E4 and urea in E3 and E4, compared to the C. In Experiment II, lower (p < 0.001) concentrations of aspartate aminotransferase, alanine-aminotransferase, total protein, and Mg were determined in the serum of fatteners from E1–E4 compared to the C. Even though values of all analyzed blood markers differed among the groups, in most cases they fitted within reference values for the species, which indicates the maintenance of body homeostasis. Study results show that there are no contraindications to the use of pea and blue lupin seeds as alternative feed materials to SBM-GM in pig fattening.

The reproductive traits of sows are of paramount importance in the production of high-quality pork. The world experience of pig farming shows the need to solve first of all the feed problem. Diets unbalanced in the content of vitamins restrain the manifestation of genetically inherent high prolificacy of sows. The purpose of the research was to study the influence of feeding the vitamin feed additive “LipoCar” on the reproductive traits of sows and the biochemical parameters of blood serum. The results of research on the introduction of vitamin feed additive “LipoCar” into the diet of pregnant sows have been presented in the article. The experiment has been carried out in the production conditions in JSC “Linevsky pedigree farm” on sows of Large White breed. Pregnant sows have received a basic diet, balanced for all the normalized elements of nutrition. Sows of the experimental group in the composition of the basic diet fed the feed additive “LipoCar”. The dosage of the drug “Lipocar” was 2,1 g/head/day. “Lipocar” has been fed for 20 days. The total duration of the experiment was 3 months. When introducing the vitamin feed additive “LipoCar” into the main diet of sows in the second half of pregnancy the increase in the number of piglets in the litter by 1,6-6,8 % and the weight of the litter – by 5,6-56,2 % (P ≤ 0,001) have been revealed in comparison with the control group of animals. There was a higher content of carotene in the blood serum of sows of the experimental group by 50,0 % (P ≤ 0,01), vitamin A - by 48,7 % (P ≤ 0,05), and total protein – by 4,9 % (P ≤ 0,05).

Dietary beans and peas provide fibre, resistant starch and other nutrients that are often lacking in the human diet. The influence of native starches of beans and peas (and microwaved preparations) on N utilisation, biochemical indices in blood serum and caecal ecosystem state (SCFA, bacterial enzymes, micro-organisms) was studiedin vivo. The native pea starch contained more resistant starch compared with its bean counterpart (31v.17 %); however, processing decreased these amounts to 25v.10 %. N digestibility was found to decrease considerably in all experimental groups. A considerable reduction was observed in glucose and total cholesterol concentration in rat blood serum as a result of feeding both dietary legume starch preparations under microwave treatment. This indicates that starch of bean origin activated glycolytic bacterial enzymes; however, all the analysed starches were found to reduce the activity of β-glucuronidase. In addition, both dietary bean starches significantly induced the formation of SCFA in the caecal digesta. As compared with the control group, a significant decrease in the pH of caecal and colonic digesta was demonstrated for both bean starch preparations. In comparison with the diet with native pea starch, its microwaved preparation reduced the concentrations of acetic, butyric and propionic acids among caecal SCFA and increased the pH of caecal and colonic digesta. The atherogenic index was significantly lower in rats fed microwaved pea starch. All investigated starch preparations increased the population ofBifidobacteriumspp. in caecal digesta, but were also good substrates for opportunisticEnterococcusorEscherichia coli.

The purpose of these studies was to determine status of metabolic processes in clinically healthy horses of sport breeds in spring period. Blood samples for biochemical studies were collected from 12 clinically healthy 7–9 month-old stallions of Ukrainian horse breed at Dnipropetrovsk region equestrian club. Protein (albumin, globulin, urea and creatinine) and mineral (common calcium and inorganic phosphorus) metabolic statuses, level of glucose, vitamins A and E and acid, as well as activity of hepatospecific enzymes (ALT, AST and AP) were determined using common techniques. It has been found that common protein level was within the limits of physiologic norm, although the level of albumins was decreased at the average rate of 12.0%, and the level of β- and γ-globulins was increased at the average rates of 5.2 and 11.3% respectively. AST activity was decreased at the rate of 38.0% regarding to physiological norm. Thereby, urea and creatinine concentrations were within the referent levels. Hyperglycaemia was observed in 50.0% of tested animals with maximal excess at the rate of 44.0%. Also, decreasing of common calcium and inorganic phosphorus levels was determined at the rate of 16.0 and 58.6%, vitamins А and Е — at the rate of 64.0 and 48,6% respectively, in comparison to lower level of physiological norm. The average index of acid capacity reached maximal referent levels. At the same time, it was increased in 33.3% of animals. Therefore, detected changes in biochemical indices in horse blood evidence that various metabolic disorders progress in clinically healthy stallions at spring and may furtherly lead to the appearance of metabolic syndrome

During modeling of esophageal alkali burns 1 and 2 degrees in immature rats were observed violations of various metabolic systems, melanin administration helped to normalize the biochemical parameters. It was shown that under the esophageal burns there occurred violations of protein (total protein, albumin), nitrogen metabolism (creatinine, urea) metabolism of carbohydrate (glucose) and lipids (cholesterol), changed the activity of enzymes (GOT, GPT, CC), violated fluid and electrolyte balance (K +, Na +, Cl-, Ca2 +, Mg2 +, phosphates), while the introduction of melanin contributed to the normalization of these indicators. The most effective dose were of 0.5 mg/ kg and 1 mg/kg. There were found anti-toxic properties of melanin, which may be a promising drug for the normalization of metabolism in patients with burns of esophagus and prevent its complications.
