Abstract This study aims to evaluate the effects of medium and high UV-B radiation on leaves of Acanthopanax senticosus (Rupr. et. Maxim.) Harms. Two-year-old potted A. senticosus plant samples were respectively exposed to two levels of artificial, biologically effective UV-B radiation under glasshouse-controlled conditions: 1.972KJ/m2 and 3.442KJ/m2. Ordinary sunlight treatment was included as a control group, in which major effects of UV-B were observed. It was discovered that UV-B enhanced the medicinal value (especially eleutheroside B and E) of A. senticosus but impaired its growth. The sensitivity of leaves to UV-B radiation varied across different parts of the plant, among which the upper leaves responded most strongly. Furthermore, multiple types of phenolic compounds are synergistically involved in stress resistance in different aspects, including up-regulation of UV-absorbing substances (C6C3C6-type, kaempferol and rutin) and antioxidant enzyme synergists (C6C1-type, salicylic acid) as well as down-regulation of antioxidants (C6C3-type, p-coumaric acid). Conclusion of this study may provide a new perspective to improve the exploitation of A. senticosus.

The modern state of social-economic processes development demands increasing the level of food safety of the state, especially providing population by the high quality foods of domestic production, specifically by pork. One of criteria for estimating pigs' meatness is determining the fat thickness in different points of a trunk. The informative content of measuring in different parts of a trunk is different and it needs detailed study. The fat thickness is the most common as trait for pigs' meatness in the practice of pig breeding because it has high correlation with meat yield in carcasses. The aim of our research was the comparative study of fat deposition regularities in different parts of a trunk of Large White and Mirgorod pigs in different age periods. For conducting researches 24 pigs of both breeds with average live weight about 40 kg and at age not more 4 months were selected. The fat thickness was measured at live animals using ultrasonic device Draminski in such points: on withers, the level of the 6-7th thoracic vertebra, the level of the 1st-2nd loins vertebra and sacrum. Measuring the fat thickness was carried out at the age of 4, 5, 6, 7 and 8 months. During researches it was carried out the statistical processing of obtained material. Reliability of obtained indexes of productivity was determined. Regularities of formatting fat thickness and fat deposition rate depending on the age were studied. For the results of researches it has been studied and compared economically valuable traits of the most spread domestic pigs of Large White and Mirgorod breeds. By comparative study of growth and development of young pigs of experimental and control groups it has been found that animals of Large White breed differed by lesser fat deposits in all points of measuring. Thus, at 6-months’ age they had lesser thickness of fat in all parts of a trunk. More expressed tendency was at withers and the level of the 6-7th thoracic vertebra, at that in the first case the difference between groups was reliable (p < 0.01). The fat deposition rate in young pigs of both breeds was not the same in different points of measuring along a trunk. Above mentioned tendencies were intensified with the age. Purebred animals of intrabreed type LW-1 at 7-months’ age had reliable less thickness of fat in comparison with the control group: on withers (p < 0.01), at the level of the 6-7th thoracic vertebra, the level of the 1st-2nd loins vertebra (p < 0.05) and on sacrum (p < 0.01). In future, according to economic and scientific expediency, the animals of Mirgorod breed were excluded from the experiment. Concerning Large White breed, the researches were finished when animals were at 8 months’ age. The process of fat deposition in Large White pigs was less intensive in comparison to Mirgorod breed. The highest relative rate of fat thickness increase in both breeds was observed at the level of the 1st-2nd loins vertebra. By statistical processing of the obtained materials it has been found that the difference of average arithmetical indexes (as absolute and relative) between the experimental and control groups during growth and development had distinct tendency to increasing in all points of measuring. The reliability of the difference between the averages in groups with the age of animals increased. A higher reliability of data was obtained at measuring of the front parts of a trunk of pigs at the level of the 6th-7th thoracic vertebra and on withers. The carried out researches at all points of measuring give the reason to confirm that the fat deposits of Large White pigs are less comparing to Mirgorod breed. Conclusions. 1. Carcasses of animals of intrabreed type ULW-1 are comparatively more technologically suitable and economically beneficial for agricultural proceeding industry. 2. Animals of intrabreed type ULW-1 at 7-months’ age had reliable less thickness of fat in comparison with the control group: on withers, at the level of the 6-7th thoracic vertebra, the level of the 1st-2nd loins vertebra and on sacrum. 3. The process of fat deposition in Large White pigs was less intensive in comparison to Mirgorod breed.

Castor bean (Ricinus communis) seeds contain ricinine, an alkaloid with insecticidal and insectistatic activities. Elicitation with salicylic acid (SA) has proven to stress R. communis and might modify the ricinine concentration. The aim of this study was to evaluate the concentration of ricinine in the bagasse of seeds from R. communis elicited with exogenous SA under greenhouse conditions. Plants were grown and divided into five groups, which were sprayed with SA and drench with 50 mL 60 days after sowing with concentrations of SA (0, 100, 300, 600 and 900 µM). Clusters were mixed and separated according to the treatment, and dried. The seeds were ground, the oil was extracted by Soxhlet with hexane, and then the bagasse was extracted with methanol. Ricinine was determined by HPLC. Elicitation did not change the plant height or diameter; the control group had 9.17 µg mL−1 of ricinine; and the concentrations followed a hormesis curve with the peak at 300 µM of SA that had a ricinine concentration of 18.25 µg mL−1. Elicitation with SA might be a cost-effective technique to increase ricinine from R. communis bagasse.

The economic efficiency of the applying the complex to increase the stress resistance of horses during participation in competitions and demonstrative performances has been determined in this work. Thus, the sports success of horses with application of complex methods to increase the stress resistance during participation in competitions and demonstrative performances and horses trained on the usual training system has been compared; the economic effect of applying some complex methods to increase the stress resistance of horses during participation in competitions and demonstrative performances has been investigated. The research has been carried out on 10 heads of horses of the jumping group of Dergachy child and youth horse racing school. Based on the results of horses` participation in competitions and taking into account the higher nervous activity types, two equivalent groups – control and experimental by five heads in each have been formed. The complex methods to increase the stress resistance have been introduced in training system of horses of the experimental group; training of horses of the control group remained unchanged. The calculation of expenses for participation in competitions has been carried out by drawing up expenditures for transportation of horses, nutrition and accommodation of the team, starting contributions and the cost of renting stables. The total number of starts has been determined by multiplying the number of heads of horses by the number of starts of one head during the period of competitions. The number of successful starts has been calculated by a percentage of starts with the prize places from the total number of starts. To determine the economic efficiency of the application of the complex methods to increase the stress resistance of horses the amount of expenses per successful start by dividing the total amount of costs for the number of successful starts was calculated. It has been established that the economic efficiency of the applying of the complex methods to increase the stress resistance of horses is 1194,75 UAH for one successful start. The results of the research allowed to recommend the application of the developed method to increase the stress resistance in the training system of horses in order to increase the effectiveness of participation in competitions and reducing costs for each successful start.

Sports form the metabolic response caused by the body’s adaptation to increased physical stress, which leads to the restructuring of metabolism for energy and plastic maintenance of sport activities. The restructuring of carbohydrate and lipid metabolism is caused primarily by the increasing energy request body, depending on type and intensity of sports activity. In this research blood serum lipids were studied depending on the orientation of the training process. A total of 108 athletes (men and women) aged 15 to 20 years of different sports qualification (I sports category, Candidate Master of Sports and Master of Sports) were examined, and a control group of 28 persons of the same age and gender. Depending of the direction of the training process there were isolated 3 groups: cyclical sport that develops mainly endurance (academic rowing); sports of complex nature (football, volleyball, handball and Nordic combined); and complex coordinated sports (artistic gymnastics). Were studied: total cholesterol, high density lipoproteins, low-density lipoproteins, atherogenic coefficient and triglycerides. The study was conducted in the preparatory period of the training cycle. The research had shown that the level of blood lipids depends on the orientation of training process and sports training. The most marked reduction of total cholesterol and high-density lipoproteins has been observed both in men and women in cyclic kinds of sports, developing mainly stamina that indicates that intense exercise in athletes who train primarily for endurance, cause the connection of lipids to the processes of energy supply of muscle activity.

Background: Oxidative stress is imbalance between aggressive and defensive system. Overproduction of oxidative stress contribute in pathogenesis of many diseasesincluding Parkinsonism, Alzheimer diseases, apoptosis, hepatic fibrosis ,chronic kidney failure and liver steatosis etc . There are several OTC drugs including NSAIDs that generate oxidative stress when administered. So there is a need to explore about these drugs. Therefore this study was designed to evaluate the oxidative stress potential of Acetaminophen, acetyl salicylic acid and Celecoxib NSAIDs. Objective: The present study is design to investigate the oxidative stress of NSAIDs of acetaminophen, aspirin and Celecoxib drug with reference to the hydrogen peroxide. Material and method: The Experimental protocol was designed for estimate the level of oxidative stress in NSAIDs treated animals against hydrogen peroxides. Animal of control group received only vehicle throughout experimental protocol. Rats of AAP group, ASA group ,CX group were exposed to acetaminophen (150mg/kg; orally) acetyl salicylic acid (300mg/kg ;orally) and Celecoxib (50mg/kg; orally) for forty two days . Rodent of HP group were challenged with Hydrogen peroxides (0.5%) with same schedule as above. At end of experimental protocols, all the animals were sacrificed and their organ were identified and collected for oxidative stress estimation and histological examination. Result: NSAIDs administration caused increase in oxidative stress measured in terms of SOD, CAT, MDA, GSH and GPx. HP administration produced maximum oxidative stress compare to all other groups. Oxidative parameter i.e. SOD, CAT, GSH and GPx were found to be decreased as compare to control rats. However MDA were found to be increased as compare to control rats. Additionally, CX produced less oxidative stress compare to other NDAIDs. Further, histological examinations support the biochemical results. Conclusion: From the above observations it can be concluded that NSAIDs have oxidative stress potential and generate oxidative stress and damage the organs when administrated chronically. Thus, these drugs should be used judiciously.

Many reports have shown that grains play an important role in our daily lives and can provide energy and nutrients to protect us from various diseases, and they are considered to be indispensable parts of our lives. It has been reported that some constituents in grains could exert functional effects against HIV infections and multiple cancers. Zymolytic grain can produce some new useful molecules and thus support the cell nutrients in the human body. In this study, the effects of zymolytic grain extract (ZGE) supernatants on the changes of nematode indicators were investigated, including lifespan, self-brood size, and body length in environmental conditions (temperature, ultraviolet radiation or 5-fluoro-2′-deoxyuridine (FUDR) stimuli). We found that, compared to the control group, the ZGE supernatant-feeding group could prolong the lifespan of nematodes under normal conditions. More importantly, ZGE supernatants could improve the ability of nematodes to resist stress. When the concentration of FUDR was 400 or 50 μM, the ZGE supernatant-feeding group could prolong lifespan by an average of 38.4% compared to the control group, and the eggs of the ZGE supernatant-feeding group could hatch and develop into adults. These results indicated that ZGE could protect C. elegans from external stress and thus prolong their lifespan and improve the physiological state of nematodes. Therefore, ZGE supernatant has potential to be used as a nutritional product in antioxidant and anti-aging research.

We evaluated the effects of two types of colony cages, in which rabbit does were always in a group (C1), and where they were in combi cages furnished with removable internal walls to allow both individual and grouphousing (C2), in addition to the control group (C: conventional individual cage), on welfare, reproductive performance, and global efficiency. Forty-eight New Zealand White nulliparous rabbit does underwent artificially insemination (AI) and were divided into three groups, and reared in the different systems for about 1 year. The reproductive rhythm provides AIs at weaning (30d). In the C1 system, does were continuously grouped, while in C2, walls were inserted four days before kindling and removed 1week after it (60% of the timesheet in group). Reproductive traits and behaviour were evaluated during the entire year. The behavioural observations were performed around days 7, 36, and 44, corresponding to the inclusion of the does in the maternal cages, the insertion of walls four days before kindling, and the removal of the walls 1week after parturition in the C2 group, respectively. The percentages of does with severe skin injuries and the distribution of the injuries on different parts of body were also registered. Does reared in conventional cages showed the greatest presence of stereotype behaviours, while the C1 group showed the highest (p < 0.05) incidence of aggressiveness after regrouping (attack, dominance features, and lower allo-grooming) in comparison to the C2 group (17% and 22%, in C2 and C1 does, respectively).Individually caged does achieved the best productive performance (sexual receptivity, fertility, kindling rate, and number of kits born alive and at weaning). The C1 group showed the lowest performance (p < 0.05), whereas C2 showed an intermediate one. Does housed in the combi cage (C2) had higher (p < 0.05) receptivity and fertility rates and higher numbers of kits born alive and at weaning (79.2% and 76.2%; 7.95 and 7.20, respectively) than the C1 group, but lower values (p < 0.05) than does that were individually housed.
