Cimicifuga dahurica - многолетнее растение семейства Ranunculaceae. В тибетской медицине С. dahurica входит в состав сборов, применяющихся при болезнях «гза» («болезни, насылаемые духами»: при инсультах, параличах и других нарушениях функций нервной системы). В середине ХХ века настойку С. dahurica использовали для лечения гипертонической болезни. С. dahurica оказывает седативное действие, ограничивая двигательную, ориентировочно-исследовательскую активность и рефлекторную возбудимость животных, а также увеличивая продолжительность наркотического сна. Цель исследования - оценка стресс-протективного действия настойки С. dahurica при хроническом эмоциональном стрессе. Методика. Исследования проведены на крысах Wistar. Длительный эмоциональный стресс воспроизводили четырехдневной иммобилизацией животных в пластмассовых пеналах с одновременным погружением их в воду. Настойку С. dahurica вводили животным (0,5 мл/кг) в течение 7 сут до моделирования эмоционального стресса и ежедневно перед помещением их в пеналы. Определяли выраженность триады Селье, уровень адренокортикотропного гормона кортикостерона и катехоламинов в плазме крови, содержание малонового диальдегида, и активность каталазы в сыворотке крови, а также активность супероксиддусмутазы в эритроцитах. Результаты. Установлено, что настойка C. dahurica повышает устойчивость животных к длительному эмоциональному стрессу, ограничивая инволюцию иммунокомпетентных органов - тимуса и селезенки на 22% и 24%, соответственно. Выраженность гипертрофии надпочечников снижалась на 34%, уменьшалось развитие язвенных повреждений слизистой оболочки желудка, что может быть связано с торможением функции симпатоадреналовой и гипоталамо-гипофизарно-адренокортикальной систем, ингибированием свободнорадикальных процессов с одновременной активацией эндогенных антиоксидантных систем. Исследуемое фитосредство ингибировало гиперактивацию перекисного окисления липидов, снижая уровень малонового диальдегида на 24%, а также повышало активность эндогенной антиоксидантной системы, увеличивая активность каталазы и супероксиддисмутазы в 1,6 и 1,3 раза соответственно. Заключение. Настойка С. dahurica в дозе 0,5 мл/кг при длительном эмоциональном стрессе оказывает стресс-протективное действие, уменьшая выраженность стресс-индуцированных изменений, ограничивая гиперактивацию центральных стресс-реализующих систем, коррегируя эндогенную антиоксидантную систему организма. Выявленный стресс-протективный эффект исследуемого фитосредства обусловлен содержанием в его составе комплекса биологически активных веществ, таких как фенольные соединения, сапонины. Cimicifuga dahurica (Turcz.) Maxim. is a perennial plant of the Ranunculaceae family. In Tibetan medicine, C. dahurica is included into medicinal collections used for the treatment of gza diseases (diseases “inflicted by demons”), such as stroke, palsies, and other functional disorders of the nervous system. In mid-20th century, the C. dahurica tincture was used for the treatment of hypertension. The C. dahurica tincture has a sedative effect; it limits motility, exploratory activity, and reflex excitability in animals and prolongs the narcotic sleep. The aim of this study was to evaluate the stress-protective effect of C. dahurica tincture in chronic emotional stress. Methods. Experiments were performed on Wistar rats weighing 180-200 g. Chronic emotional stress was produced by four-day restraint of animals in plastic cases with simultaneous water immersion. The C. dahurica tincture was administered to animals at a dose of 0.5 ml/kg for 7 days, once a day; the last dose was administered 30 min prior to testing. The following parameters were determined: intensity of the Selye’s triad, plasma concentrations of ACTH, corticosterone, and catecholamines; serum concentration of malonic dialdehyde; serum activity of catalase; and superoxide dismutase activity in red blood cells. Results. The C. dahurica tincture increased the tolerance to chronic emotional stress and restricted involution of immune-competent organs, the thymus and spleen, by 22% and 24%, respectively (p<0.05), adrenal gland hypertrophy by 34% (p<0.05), and development of stress-induced stomach ulcers. These effects could be due to inhibition of the sympathoadrenal system and the hypothalamic-pituitary-adrenocortical axis, inhibition of free-radical processes, and simultaneous activation of endogenic antioxidant systems. The C. dahurica tincture inhibited lipid peroxidation processes thus reducing the content of malonic dialdehyde by 24%. Also, the tincture potentiated the endogenous antioxidant system by increasing activities of catalase and superoxide dismutase 1.6 and 1.3 times, respectively. Conclusion. The stress-protective effect of the plant remedy is due to contained bioactive substances, such as phenolic compounds and saponins.

Purpose: To study the effect of Rhus chinensis Mill. extract (RCME) on diethylnitrosamine (DEN)-induced liver cirrhosis in rats. Methods: RCME was obtained by extracting the dried Rhus chinensis Mill. in water. Liver cirrhosis rat model was prepared by injecting with DEN once a week for 8 weeks. After 8th-week of RCME treatment, biochemical index and oxidative stress were determined in DEN-induced liver cirrhosis in rats. Results: Compared with model group, plasma concentrations of alanine transaminase (ALT, 125.3 ± 4.1 U/L) and aspartate aminotransferase (AST, 152.4 ± 3.5 U/L) decreased significantly (p < 0.01) in the 8th week. Rhus chinensis Mill. extract (RCME) significantly decreased malondialdehyde (MDA, 0.18 ± 0.02 umol/L) and superoxide dismutase (SOD, 0.76 ± 0.05 U/mg protein) in DEN-induced liver cirrhosis in rats (p < 0.01) when compared with model group. Conclusion: RCME protects against diethylnitrosamine-induced liver cirrhosis in rats. However, further investigations are required to ascertain the plant extract’s suitability for the clinical management of liver cirrhosis.

The combined protective effect of a polyphenol-rich extract, isolated from Geranium sanguineum L. (PC), and a novel naturally glycosylated Cu/Zn-containing superoxide dismutase, produced from the fungal strain Humicula lutea 103 (HL-SOD), in the experimental influenza A virus infection (EIVI) in mice, induced with the virus A/Aichi/2/68 (H3N2), was investigated. The combined application of HL-SOD and PC in doses, which by themselves do not defend significantly mice in EIVI, resulted in a synergistically increased protection, determined on the basis of protective indices and amelioration of lung injury. Lung weights and consolidation as well as infectious lung virus titers were all decreased significantly parallel to the reduction of the mortality rates; lung indices were raised. The excessive production of reactive oxygen species (ROS) by alveolar macrophages (aMØ) as well as the elevated levels of the lung antioxidant enzymes superoxide dismutase (SOD) and catalase (CAT), induced by EIVI, were brought to normal. For comparative reasons the combined protective effect of PC and vitamin C was investigated. The obtained results support the combined use of antioxidants for the treatment of influenza virus infection and in general indicate the beneficial protective role of combinations of viral inhibitors of natural origin with diverse modes of action.

The objective of research was to study the state of prooxidant and antioxidant systems in the tissues of the lungs, kidneys, pancreas and salivary glands at burn disease. The intensity of the free radical processes was evaluated on the basis of the content of malondialdehyde (MDA) and antioxidant system – based on the indexes of its enzymatic chain: superoxide dismutase and catalase in homogenates of the studied organs. It has been found that changes in experimental burn disease depend on the studied organs and the stage of burn disease. The activation of free radical processes observed in all investigated organs (lungs, kidneys, pancreas and salivary glands). Reactive oxygen species induce lipid peroxidation, which is a universal marker of tissue damage. MDA appears in the body during degradation of polyunsaturated fatty acids and it’s a marker of lipid peroxidation and oxidative stress. It was found the increasing of MDA in all organs, especially in the lungs and kidneys at stage of burn shock. Under these conditions it was observed the decrease of superoxide dismutase and catalase in all investigated organs. At burn disease there is development of disbalance between the action of prooxidant and antioxidant systems due to the activation of free radical processes.

Antioxidant Protection System

A highly relevant problem of modern veterinary science is the study of features and mechanisms of combined action of the most common heavy metals – cadmium and plumbum and their influence on the body of humans and animals in the regions of Ukraine under technogenic pollution. The purpose of the work was to study the influence of heavy metals on the state of the antioxidant protection system of cows, in particular on the content of lipid peroxidation products (malonic dialdehyde, lipid hydroperoxides and diene conjugates), and activity of antioxidant enzymes (glutathione peroxidase and superoxide dismutase), depending on the distance to the heaps of mines in the coal basin. The study objects were cows of black-and-white breed at the age of 3–7 years. It was established that this parameter in the place with the highest concentration of diene conjugates in the blood of cows was by 25.8 % higher compared to the place of low concentration and 12.1 % higher compared to the place with medium concentration. In the place with the highest content of lipid hydroperoxides in the blood of cows the parameter was 23.7 % higher compared to the cows from the place with the low content. The concentration of lipid hydroperoxides in the blood of cows from the place with the medium content was 16.7% higher compared to the cows from the place with the low content. The parameter from the place with the lowest content of lipid hydroperoxides in the blood of cows was 12.1% lower compared to the place with the highest content. The level of malonic dialdehyde in the blood of cows from the technogenic pollution zone in the place with the largest amount was higher by 36.2; 34.0 and 18.8 % – compared to places with medium and low levels, respectively. The activity of superoxide dismutase in the blood of cows in the place with its highest activity was 0.284 ± 0.0099 % block. reac/g Hb, and in the place with the lowest activity – 0.23 ± 0.0051 % block. reac/g Hb. The activity of glutathione peroxidase in the blood of cows in farms of the technogenic pollution zone depended on the distance to the mine. These researches will further develop effective methods of treating cows under the influence of heavy metals, in particular regarding the antioxidant system.

Antioxidative Effects

Acute p.o. administration of absolute ethanol (10 ml/kg) to fasted mice would produce extensive renal failure. Pretreatment with p.o. administration of propolis ethanol extract (PEE) could prevent such renal failure effectively and dose dependently. This renal protective effect of PEE may be contributed, at least in part, to its antioxidative activity. The maximal antioxidative effect against absolute ethanol (AE)-induced renal failure could be observed 1 hour after PEE administration. In order to further investigate the renal protective mechanism of PEE, lipid peroxidation and superoxide scavenging activity were conducted in vivo. PEE exhibited dose-dependent antioxidative effects on lipid peroxidation in mice renal homogenate. Results indicated that mice with acute renal failure have higher malonic dialdehyde (MDA) levels compared with those in PEE administered mice. It was concluded that the renal protective mechanism of PEE could be contributed, at least in part, to its prominent superoxide scavenging effect; hence, it could protect, indirectly, the kidney from superoxide-induced renal damages.
