Complex research into biochemical aspects of the functioning of the antioxidant system for the protection of sperm of the breeding boars has established that the intensity of the flow of peroxide oxidation of lipids in germ cells is much higher than in the extracellular space. Reactions of free radical peroxide oxidation of proteins and lipids in the semen of healthy breeding boars are characterized by a stable level of activity that is necessary for the normal course of implementation of processes of the reproductive function. All components of the antioxidant system stay in mutual compensatory ratios under physiological conditions. As a rule, reducing the concentration or activity of some antioxidant enzymes leads to corresponding changes in others. The main antioxidants of the germ cell genomes are superoxide dismutase and ceruloplasmin. Catalase is a key enzyme that neutralizes H2O2 in the semen fluid of breeding boars. The content of total proteins in the semen of the synthetic line SS23 animals is greater (p < 0.05) than in the breeding boars of the large white breed. The processes of the oxidative modification of proteins in the animals body of the synthetic line runs more intensely, as it is evidenced by the higher content of the aldehyde and ketodinitrophenyl hydrazones of the main and neutral character in the sperm cytoplasm.

Abstract Dairy goat breeding is widespread worldwide. Goat milk and other derivative products are an important part of nutrition. Dairy products are the most important part of goat breeding; therefore, lactation performance is a relevant issue. The purpose of this study was to evaluate antioxidant system characteristics in Saanen goats depending on lactation performance. The experiment was conducted in the north-western region of Russian Federation, in the laboratories of the biochemistry and physiology departments at FSBEI of Higher Education «SPbSAVM». The three experimental groups included 30 Saanen goats each, 2nd–3rd lactations, selected using matched pairs method. 1st group included low milk producing ability goats (&lt; 600 kg of milk yield per year), 2nd group included average milk producing ability goats (600–800 kg of milk yield per year), 3rd group included high milk producing ability goats (&gt;800 kg of milk yield per year). The blood samples were taken once: at peak lactation performance (45 days after parturition). The blood levels of lipid peroxygenation markers (malondialdehyde, dienketone and conjugated dienes) and superoxide dismutase and catalase activity were assessed by standard methods. Results presented as mean±standard error of the mean. Student’s t-test was used after proving normal distribution. Level of significance is labeled as P &lt; 0.05. The results are displayed in table 1 and 2. After analyzing the received data of antioxidant system characteristics, we found a high intensity of free-radical oxidation in high milk producing ability goats. This results in oxidative stress development. Activity of anti-oxidizing enzymes was elevated; therefore, free-radical oxidation is intensive. Consequently, these data allow us to take into consideration exogenous anti-oxidizing agents administration in high milk producing ability goats in order to reduce oxidative stress.

The aim: Objective of the research was to study peculiarities of free radical oxidation and antioxidant protection parameters of the oral fluid in children with chronic catarrhal gingivitis with underlying diabetes mellitus. Materials and methods: Oral fluid was examined in 105 children aged 12 including somatically healthy ones with intact periodontium and chronic catarrhal gingivitis, suffering from diabetes mellitus up to 5 years and more than 5 years with chronic catarrhal gingivitis. The parameters of lipid peroxide oxidation (level of diene conjugates, Malone dialdehyde) and antioxidant protection (activity of SOD and catalase, POM, whole protein; ceruloplasmin; НS-groups) of the oral fluid were determined. Results: The results obtained are indicative of available probable difference in the examined parameters among children depending on their general state of health and periodontal tissue condition. The best parameters were found among somatically healthy children with intact periodontium. They deteriorated in children with chronic catarrhal gingivitis available irrespective of their general state of health. They reached the most critical level in children with diabetes mellitus lasting longer than 5 years. Conclusions: The course of chronic catarrhal gingivitis in children, both somatically healthy and those suffering from diabetes mellitus, is associated with increased parameters of lipid peroxide oxidation and decreased enzymatic activity of the antioxidant protection system of the oral fluid. The most considerable changes are found in patients suffering from diabetes mellitus lasting more than 5 years.

Research into the accumulation patterns of protein oxidative modification (POM) products and lipids in Crohn’s disease (CD) and ulcerative colitis (UC) could have important implications for understanding the pathogenesis and improving the diagnosis and therapy for these diseases. The aim of this study was to investigate the aspects of free radical oxidation (FRO) in the large bowel and their possible correlations with clinical symptoms of UC and CD. In the Wistar rat model used in the experiment, CD was induced with 2,4,6-trinitrobenzenesulfonic acid, and UC was induced with oxazolone. Clinical status was assessed using the Disease activity index (DAI). Lipid peroxidation (LPO) products were measured in the heptane and isopropanol phases of the intestinal mucosa extract. POM products were measured following spontaneous and stimulated oxidation. The DAI ( Me (Q25–Q75)) was increased in both CD and UC on days 3 and 7 of the experiment: for CD, it was equally increased on days 3 and 7 (7 (3-7)) and was 11 (11–11) and 11 (9–11) for UC on days 3 and 7, respectively. The amount of primary, secondary and end LPO products in the heptane and isopropanol phases, as well as the total amount of POM products, was increased in the homogenized mucosa of the large bowel. In the CD group, the relative content of secondary basic POM products was increased on day 7 of the experiment. The following patterns of FRO were revealed: accumulation of LPO products in the UC group and accumulation of POM products in the CD group; UC is characterized by the accumulation of mostly LPO products in the heptane phase and secondary LPO products in the isopropanol phase; CD is characterized by the accumulation of secondary basic POM products. DAI scores were correlated with the amount of LPO products in the isopropanol phase and the amount of POM products in the spontaneous oxidation mode. The highest number of strong correlations was observed in the UC group. Our findings suggest a very serious contribution of FRO changes to the pathogenesis of UC and CD, meaning that LPO and POM products could be regarded as diagnostic markers and indicators of treatment efficacy.

Aim. Study of the relationship between the parameters of free radical oxidation of proteins and lipids in the murine kidneys in the post-resuscitation period after stopping the systemic circulation, depending on their resistance to hypoxia. Methods. The systemic circulation was stopped by intra-thoracic clamping of the neurovascular bundle for 5 minutes, performed under general ether anesthesia in male noninbred white rats, divided after testing into two groups based on resistance to hypoxia. The observation period lasted for 35 days. In the homogenates of kidney tissues, the content of products reactive to tiobarbituric acid, carbonylated proteins, the formation of metal-catalyzed carbonylated proteins and bitirozin were determined. Results. The characteristic manifestation of oxidative stress in the recovery period after stopping blood circulation and resuscitation was found to be reciprocity of the relationship between the levels of lipoperoxidation and oxidative modification of proteins. Highly resistant to hypoxia animals were characterized by high resistance of proteins of kidney tissue to free radical oxidation against the background of high levels of lipid peroxidation. On the contrary, in animals non-resistant to hypoxia, against the background of relatively low values of lipoperoxidation, high levels of oxidative modification of proteins, both initial and induced, were recorded. Conclusion. In post-resuscitation period in highly resistant to hypoxia animals, marked activation of lipoperoxidation occurs accompanied by a transient increase in the carbonylation of proteins in the early observation period; for low-resistant to hypoxia animals high intensity of carbonyl stress against the background of the relative «preservation» of lipid structures of the cell is characteristic, which persists throughout the post-resuscitation period, which can make a significant contribution to kidney damage, increasing the risk of renal failure.
