Purpose Evaluation of the effect of yoghurts enriched with a complex of vegetable additives on the state of the antioxidant defense system, the content of triglycerides and cholesterol in rats exposed to toxic seeds with cadmium chloride. The purpose of this paper is evaluation of the effect of yoghurts enriched with a complex of vegetable additives on the state of the antioxidant defense system, the content of triglycerides and cholesterol in rats exposed to toxic cadmium chloride. Design/methodology/approach The studies were carried out on 72 male rats (Wistar), divided into six groups (n = 12): control, model of cadmium intoxication and receiving the developed dairy product, enriched with appropriate biologically active supplements (rosehip, rowan and hawthorn berries syrup and grape peel extract [rich in resveratrol]). Biochemical parameters of blood, homogenates of the liver and kidneys were analyzed. Findings The intensity of lipid peroxidation processes (in the liver, kidneys and erythrocytes) decreased in the group receiving dairy products enriched with berry syrups and grape peel extract (rich in resveratrol). The activity of catalase, total antioxidant activity and superoxide dismutase increased. In the groups receiving dairy products enriched with berry syrups, the total protein level in the blood increased, compared with Group 2. The content of triglycerides and cholesterol levels in groups receiving dairy products decreased significantly compared to animals intoxicated with cadmium chloride. Originality/value The topic of cadmium’s toxic effects on human and animal health and methods for solving this problem is very relevant.

Aim: Cancer is one of the leading causes of death in the world. The aim of this research was to study the indices of pro- and antioxidant systems in rats with dimethylhydrazine (DMH)-induced colon carcinogenesis on the background of the enterosorbent AUT-M use. Materials and methods: The study was performed on 70 white male rats weighing 200–250 g. Adenocarcinoma of the colon was simulated by subcutaneous injection of the DMH (Sigma-Aldrich Chemie, Japan) at a dose of 7.2 mg/kg once a week during 7 months. Enterosorbent AUT-M was administered intragastrically daily for 21 days after simulation of carcinogenesis at a dose of 1 ml of suspension per 100 g of animal body weight. The state of the pro- and antioxidant systems was studied by the content of oxidative modification of proteins products (OMP), the activity of superoxide dismutase (SOD), catalase (CAT), contents of ceruloplasmin (CP) and reduced glutathione (GSH). Results: It was found that DMH-induced colon carcinogenesis in rats is accompanied by disorders in the antioxidant defense system and activation of free radical oxidation processes. Enterosorbent AUT-M provides a significant reduction in the content of OMP370 and OMP430 in both blood serum and liver homogenate of rats. Moreover, the use of enterosorbent AUT-M demonstrated a significant increase in the activity of SOD, CAT, content of GSH and a decrease in CP content in investigated tissues. Conclusion: The use of enterosorbent AUT-М demonstrated prominent potential suppression for oxidative stress and positive effect on antioxidant defense system in rats with DMH-induced colon carcinogenesis.

Background: Cadmium is an environmental pollutant which can induce the overproduction of free radicals while suppressing the antioxidant defense system. Curcumin is considered a free-radical scavenger and a potent antioxidant. This study was conducted to investigate the effect of curcumin on serum antioxidant enzymes and histopathological changes in mice treated with cadmium. Methods: In this experimental study, adult mice were divided into four groups, namely, control, cadmium chloride (5 mg kg−1), curcumin (100 mg kg−1), and curcumin+cadmium chloride. The animals received curcumin 24 h prior to cadmium chloride injection. After 24 h, blood samples were collected and used to assess the levels of malondialdehyde (MDA), antioxidant enzymes activity (catalase, superoxide dismutase, and glutathione peroxidase), total glutathione, total thiol, and hydrogen peroxide. Histopathological evaluation was also performed for testicular tissue. Results: Mice treated with cadmium showed a significant ( p < 0.001) decrease in the activity of antioxidant enzymes, serum amounts of total glutathione and total thiol, and the diameter of seminiferous tubules compared to the control group. This pollutant also significantly ( p < 0.001) increased serum levels of MDA and hydrogen peroxide and the lumen diameter of seminiferous tubules compared to the control group. In the curcumin+cadmium group, curcumin significantly ( p < 0.001) reversed the adverse effects of cadmium, compared to the cadmium group. In addition, curcumin alone significantly ( p < 0.001) increased serum glutathione peroxidase activity and thiol content compared to the control group. Conclusion: Curcumin, as a potent antioxidant, could compensate the adverse effects of cadmium on lipid and protein peroxidation, potentiated serum antioxidant defense system, and ameliorated some morphometrical parameters in the testis of cadmium-treated mice.

Introduction. Wound healing according to modern concepts is a coordinated process that passes through certain stages with the participation of different cells and products of its vital functions that regulate the healing process. It is well known that in patients with diabetes there is a violation of the process of wound healing, although until now, all the features of diabetes underlying such an inclination have not been fully understood.The aim of the study – to identify the features of oxidative stress on the background of diabetes mellitus in the rat's homogenate when different methods of closing wounds had been used. Research Methods. The experiment was conducted on 60 male rats weighing 280–320 g, which pre-simulated diabetes mellitus and surgical wounds. To detect the activation of free radical oxidation processes, the content of active forms of oxygen (AFC), lipid hydroperoxides (HPL), diene conjugates (DK) and trienic conjugates (TC) and oxidation modifications of proteins (OMP370 and OMP430). To study the antioxidant defense system, activity of superoxide dismutase was determined. Also, the activity of catalase and sulfhydryl groups (SH-groups) was determined.Results and Discussion. The research conducted by us showed that during the wounded process, on the background of diabetes, the activity of free radical oxidation processes increased. However, in the animal skin homogenates, which are labeled "Dermabond", all indices are significantly lower than in the group of animals that have been sewed over the course of all research periods. In the early stages of scar formation (3 days), an increase in the activity of the antioxidant defense system in both groups was observed. At the same time, in the experimental group of animals, which imposed the nodal seams, the activity of SOD and catalase significantly exceeded the skin index of animals, which applied glue and made (199.81±7.59) UM and (175.02±8.31) cat/kg, respectively.Conclusion. The use of skin glue reduces the intensity of the course of free radical oxidation in the cells of the scar tissue of the postoperative wound in conditions of diabetes mellitus in comparison with the imposition of nodal sutures on it: in the skin of animals, which is applied to the "Dermabond" glue, all indicators are significantly lower than in the group of animals, which imposed seam joints, throughout all research periods.

The antioxidant defense system controls and inhibits all stages of free radical formation reactions, which start from their initiation and end with the formation of hydroperoxides and malonic dialdehyde. Disorders of the body's antioxidant defense system can be caused by both endogenous and exogenous factors and can lead to the oxidative stress development. For the purpose of the negative impact minimizing and correction of the existing disorders, both natural and synthetic origin antioxidants are used. Preference is given to antioxidants of natural origin, due to their mild action and minimal side effects. Shiitake mushrooms are known in China and Japan as a product that has nutritional and medicinal value, for thousands of years. They contain an extremely rich complex of various biologically active substances that can have antioxidant, hepatoprotective effect and influence on the liver diseases pathogenesis. The aim of the work was to investigate the effect of shiitake mushrooms thick extract on the activity of free radical processes and indicators of the antioxidant system under the conditions of paracetamol hepatitis in rats. The experimental work was being conducted on the white male rats, which were divided into 10 groups of 6 animals each. Acute hepatitis was simulated by intragastric administration of paracetamol in a dose of 1 250 mg/kg 1 time per day (for 2 days) as a suspension in 2% starch gel solution. We investigated the effect of shiitake mushrooms thick extract on the induced pathology, which was administered intragastrically 2 hours before the paracetamol introduction and daily after the lesion in a dose of 150 mg/kg of the rat’s body weight. Silibor was selected as the comparison drug, which was administered according to the same scheme like the investigated extract in a dose of 20 mg/kg of the animal’s body weight. Euthanasia was conducted on the 3rd, 7th and 10th day after the onset of the lesion. Liver homogenate and animal serum were examined. The effectiveness of shiitake mushrooms thick extract was evaluated under the conditions of the caused pathology by superoxide dismutase and catalase activity, as well as by the content of TBA-active and proteins oxidative modification products. An increasing of the TBA-active products content and the products of proteins oxidative modification in the serum and liver of animals after the toxic paracetamol exposure testifies to the liver damage and the development of acute hepatitis in rats. Decreased activity of antioxidant enzymes such as catalase and superoxide dismutase was also noted. An investigation, which was conducted by us, allowed us to reveal a positive effect of shiitake mushrooms thick extract on the activity of lipoperoxidation and oxidative modification of proteins under the conditions of white rats paracetamol lesion.

This article presents the results of research on the influence of cadmium loading on the state level of enzymatic and non-enzymatic antioxidant links of the antioxidant defense system of the organisms of young cattle, such as the activity of catalase, superoxide dismutase, glutathione peroxidase, glutathione levels, selenium, vitamins A and E. It was found that feeding bull calves with cadmium chloride at doses of 0.03 and 0.05 mg/kg of body weight helped to reduce both the enzymatic and non-enzymatic link of antioxidant protection (superoxide dismutase 31%, catalase 13%, glutathione peroxidase 23%, reduced glutathione 10%, vitamin A 28%, vitamin E 31%, selenium 20%). Toxic effects of cadmium promotes change in steady-state concentrations of radical metabolites О2–,ОН˙, НО2˙, which, in turn, trigger the process of lipid peroxidation. The lowest level of indicators of antioxidant defense system in the blood of young cattle was registered on the sixteenth and twenty-fourth days of the experiment, which is associated with increased activation of lipid peroxidation and the disturbaance of the balance between the antioxidant system and lipid peroxidation intensity. The activity of the antioxidant defense system in the blood was different for calves fed with cadmium chloride at doses of 0.03 and 0.05 mg/kg of animal mass. The more cadmium chloride in the feed, the lower the activity of the antioxidant defense system of the calves’ organisms was registered. Thus cadmium chloride depresses the antioxidant defense system, which specifically involves lowering the activity of enzymatic links (catalase, superoxide dismutase, glutathione peroxidase) and non-enzymatic links (reduced glutathione, selenium, vitamins A and E).

It was presented the results of studies of the cadmium effect loading on the activity of the glutathione system of antioxidant protection in young cattle, namely on the activity of glutathione peroxidase, glutathione reductase, glucose-6-phosphate dehydrogenase, the level of reduced glutathion. It was established that feeding of cadmium chloride to bullocks at a dose of 0.03 and 0.05 mg/kg body weight contributed to a decrease in both the enzyme and non-enzyme link of the glutathione antioxidant defense system. The toxic effect of cadmium contributes to a change in stationary concentrations of radical metabolites. О2˙ˉ, ˙ОН, НО2˙, which, in turn, initiate lipid peroxidation processes. The lowest level of glutathione indexes of the antioxidant defense system in the blood of young cattle was established on the sixteenth and twenty fourth day of the experiment, it was associated with enhanced activation of lipoperoxidation and an imbalance between the activity of the antioxidant system and the intensity of lipid peroxidation. The feeding of cadmium chloride to bullocks at a dose of 0.03 and 0.05 mg/kg of animal weight did not affect the activity of the glutathione antioxidant defense system in their blood. It was established that the greater the amount of cadmium chloride in the feed, the lower the activity of the glutathione system of the antioxidant defense of the body of bulls. Thus, cadmium chloride suppresses the antioxidant protection system, in particular, by reducing the activity of the enzyme link: glutathione peroxidase, glutathione reductase, glucose-6-phosphate dehydrogenase, and non-enzyme link: reduced glutathione.


The accumulation of heme in the organism under the influence of various hemolytic factors can cause the development of oxidative stress with the activation of free radical processes, oxidative damage to macromolecules and supramolecular complexes of cells and tissues. Under these conditions, the antioxidant defense system is activated in the organism, an important link of which is thiol compounds, particularly glutathione. Under such conditions, the processes of nitrogen and carbohydrate metabolism associated with the formation of adaptive reactions in response to stress have been investigated insufficiently. The aim of this work is to study some indicators of nitrogen and carbohydrate metabolism during the administration of hemin and the combined administration of hemin and glutathione to clarify the role of this antioxidant in the possible correction of metabolic processes. The subjects of the study were mature outbred albino male rats that received intraperitoneal injections of hemin (50 mg/kg) and glutathione (500 mg/kg) solutions, which was administered 0.5 hours before the introduction of hemin. The animals were tested 2 hours after hemin administration. The content of total and non-protein -SH groups, and the activity of gamma-glutamyltranspeptidase (GGT) in liver and kidney homogenates, glycogen content and tyrosinaminotransferase (TAT) activity in liver homogenate were studied. The content of reduced -SH groups can be an indicator of pro-antioxidant balance, GGT activity is one of the indicators of glutathione metabolism, and glycogen content and TAT activity in liver are hormone-sensitive indicators. The introduction of hemin caused a decrease in the content of total and non-protein -SH groups, glycogen content and an increase in TAT activity in liver, as well as an increase in the activity of GGT in this organ. Administration of glutathione to rats 30 minutes before the administration of hemin prevented shifts in these parameters in liver caused by the administration of hemin alone. In kidneys, an increase in the content of total -SH groups was found after the combined administration of glutathione and hemin compared with the effect of hemin alone. The results of this study may indicate a sensitivity of nitrogen and carbohydrate metabolism in rat organs to the effect of hemin and the corrective effect of glutathione under these conditions, probably mediated through an increase in the thiol component of the antioxidant defense system.
