The effect of histamine and quercetin, as well as their combined effect on the activity of superoxide dismutase, catalase and the content of reduced glutathione in the blood plasma of rats was studied. It was found that the addition to the blood of quercetin at a concentration of 0.1; 0.3; 0.5; 1.0; 5.0 mM causes an increase in superoxide dismutase activity. It was found that histamine at concentrations of .01 and 0.1 μm leads to a decrease in superoxide dismutase activity by 31 and 17 %, respectively. Whereas the biogenic amine in the lowest and highest concentrations does not change the activity of superoxide dismutase in plasma. At simultaneous introduction into blood of histamine in the maximum concentration (10.0 μm) and quercetin in concentration of 0,1; 0.5; 3.0 mM normalizes the activity of superoxide dismutase. And only the combined action of histamine of this concentration and quercetin at a concentration of 5.0 mM reduces the activity of the enzyme by 21 %. Histamine at a concentration of 0.01 μm and the simultaneous action of quercetin at a concentration of 0.1; 0.5; 3.0; 5.0 mM increases the activity of superoxide dismutase, which indicates the generation of reactive oxygen species, in particular the superoxide anion radical. It was found that the addition of whole concentrations of quercetin to whole blood causes a decrease in plasma catalase activity. The combined action of quercetin and histamine causes a decrease in catalase activity. It was found that the addition to the blood of quercetin at a concentration of 0.1; 0.3; 0.5; 1.0 mM causes a decrease in the content of reduced glutathione. Quercetin at a concentration of 3.0 and 5.0 mM causes an increase in reduced glutathione by 27 and 14 %, respectively, compared to the reference plasma. Histamine at concentrations of 10.0, 1.0 and 0.01 μm leads to an increase in the amount of reduced glutathione by 24, 26 and 19 %, respectively. And at a concentration of 0.1 μm, the biogenic amine reduces the GSH content by 39 %. With simultaneous introduction into the blood of histamine at a concentration of 10.0 μm and quercetin at a concentration of 0.1; 0.5; 3.0 mM there is an increase in the content of reduced glutathione. And only at a concentration of 5.0 mM quercetin on the background of the action of histamine (10.0 μm), the content of reduced glutathione is slightly reduced. However, with the combined action of histamine at a minimum concentration (0.01 μM) and quercetin at a concentration of 0.1; 0.5; 3.0 and 5.0 mM there is a decrease in the content of reduced glutathione. After performing a dispersion analysis, it was found that the state of the antioxidant system, both enzymatic and non-enzymatic, is significantly affected by histamine. The smallest, but significant share of the effect is on the action of quercetin in the blood plasma of rats. The indirect and significant effect of the simultaneous action of histamine and quercetin on the antioxidant system of rat plasma was revealed.

Aim. The paper studies the dynamics of the indicators defi ning the antioxidant system (AOS) and endogenous intoxication in patients with microbial eczema (ME) prior to and following treatment.Materials and methods. The experimental group consisted of patients with ME (n=30) and the control group comprising somatically healthy individuals (n=30). In this study, we determined the components of the antioxidant defence system in blood plasma and erythrocyte suspension, as well as assessed endogenous intoxication.Results. The study revealed an imbalance of indicators refl ecting the severity of oxidative stress and endogenous intoxication in patients suffering from ME. Prior to receiving treatment, the experimental group, as compared to the control group, exhibited an increase in catalase activity (CAT) up to 35.93 [32.50; 38.22] mmol / (min • l) (p < 0.001) and glutathione peroxidase (GPx) up to 1194.27 [1069.50; 1375.78] μmol / (min • l) (p < 0.001). In addition, there was a decrease in the activity of superoxide dismutase (SOD) to 13.28 [11.35; 14.10] u/l (p < 0.001), glutathione reductase (GR) to 501.46 [479.77; 542.52] mmol / (min • l) (p < 0.001) and the concentration of reduced glutathione to 1.64 [1.59; 1.78] μmol / ml (p = 0.043). We observed no statistically signifi cant changes in the total antioxidant activity (TAA) of blood plasma (0.59 [0.55;0.62] mg/l; р = 0.375) and the sulphhydryl groups (0.44 [0.41;0.47] ODU; р =0.111). The patients with ME exhibited the syndrome of endogenous intoxication (SEI), accompanied by an increase in the content of medium and low molecular weight molecules in plasma to 12.19 [11.20; 13.37] arb. u. (p < 0.001), with their content in erythrocytes being relatively normal – 15.23 [14.26; 16.44] arb. u. (p = 0.005). Following the treatment, changes in the studied parameters were of a multidirectional character in relation to the control values. An increased level of CAT and GPx (р <0,001), as well as lower values of SOD and GR, continued to be observed (р < 0.001). The TAA in serum (p = 0.308), sulphhydryl groups (p = 0.111) and reduced glutathione (p = 0.107) did not differ signifi cantly from the control values. The treatment did not reverse the SEI: the content of medium and low molecular weight molecules continued to increase in both plasma and erythrocytes, as compared to the control values (p < 0.001 in both cases).Conclusion. The obtained data confi rm the failure of mechanisms underlying antioxidant defence in patients with ME. Despite the attempt of its compensation by increasing the catalase activity, SOD control values were still not reached. An increase in the GPx activity along with a decrease in GR was observed, which could have lead, in turn, to a decrease in the concentration of reduced glutathione. The failure of the antioxidant defence mechanisms is also indicated by an increase in the content of medium and low molecular weight molecules, as well as by the development of the SEI, resulting from the excessive formation of reactive oxygen species and the inability of the antioxidant system to neutralise them.

The effects of total inhibition of catalase, induced by 3-amino-1,2,4-triazole, on the adult housefly (Musca domestica) were examined. The lack of catalase activity had no effect on the longevity of the houseflies. Inorganic-peroxide concentration was elevated at younger ages, but declined in older flies. The rate of oxygen consumption by the flies was greatly decreased and the levels of oxidized as well as reduced glutathione were augmented. Superoxide dismutase activity showed a slight increase. This study suggests that loss of catalase activity does not affect survival of houseflies due to adaptive responses.

To investigate the effects of chronic exposure to mercury we studied the red cell antioxidant system in mercury-exposed workers through the evaluation of reduced glutathione, catalase and superoxide dismutase systems. Oftheseworkers, somewerebeingexposedatthetimeand had presented urinary mercury levels considered safe for occupational exposure for at least 3 months prior to the initiation of this study, and others had been on leave for at least 6 months because of intoxication symptoms. Reduced glutathione levels were lower and catalase activity was higher in the workers which were still being exposed, compared to those on leave and controls. No differences were observed between the workers on leave and controls.

The state of the blood antioxidant system in the patients presenting with acromegaly. The objective of the present study was to evaluate the total antioxidant activity (TAA) of blood plasma, the levels of non-protein thiols and 2-thyobarbituric acid-active products (TBA-AP), superoxide dismutase (SOD) and catalase (CAT) activities as well as ceruloplasmin (CP) level in the patients presenting with acromegaly. It was shown that plasma TAA and SOD activity in this patients was on the average 20 and 30% lower respectively than in the control subjects. At the same time, the TBA-AP and CP levels increased by 50 and 40% respectively. These data suggest the development of oxidative stress in the acromegalic patients.

Deacetylasperulosidic acid (DAA) is a major phytochemical constituent ofMorinda citrifolia(noni) fruit. Noni juice has demonstrated antioxidant activityin vivoand in human trials. To evaluate the role of DAA in this antioxidant activity, Wistar rats were fed 0 (control group), 15, 30, or 60 mg/kg body weight per day for 7 days. Afterwards, serum malondialdehyde concentration and superoxide dismutase and glutathione peroxidase activities were measured and compared among groups. A dose-dependent reduction in malondialdehyde was evident as well as a dose-dependent increase in superoxide dismutase activity. DAA ingestion did not influence serum glutathione peroxidase activity. These results suggest that DAA contributes to the antioxidant activity of noni juice by increasing superoxide dismutase activity. The fact that malondialdehyde concentrations declined with increased DAA dose, despite the lack of glutathione peroxidase-inducing activity, suggests that DAA may also increase catalase activity. It has been previously reported that noni juice increases catalase activityin vivobut additional research is required to confirm the effect of DAA on catalase. Even so, the current findings do explain a possible mechanism of action for the antioxidant properties of noni juice that have been observed in human clinical trials.

Abstract Introduction Antioxidant enzymes protect the human body against the harmful effects of oxidative stress. The activity of antioxidant enzymes changes with age, and depends on dietary nutrients such as fats and vitamins, which can have a significant impact on minimizing or exacerbating oxidative stress. Aim Examine the effect of age, BMI, diet, physical activity and smoking status on the activity of erythrocyte antioxidant enzymes catalase, glutathione reductase, glutathione peroxidase glutathione S-transferase, superoxide dismutase and glutathione concentrations in healthy women. Material and methods This study included 98 healthy women aged between 20 and 65 years. All women underwent anthropometric tests: body weight, height, hip and waist circumference. Antioxidant activity in erythrocytes was measured by spectrophotometric methods. Results Catalase activity increased significantly with age (p<0.001), while superoxide dismutase activities and glutathione decreased with age (p =0.008, p =0.023, respectively). Women with a lower BMI (emaciation) had higher superoxide dismutase activity than those in the first degree of obesity (p = 0.009 Conclusions 1. Increased catalase activity with age may be a sign of a large amount of hydrogen peroxide, resulting from poorly functioning antioxidant systems in older age. 2. Decreased superoxide dismutase activity with age may indicate inactivation of this enzyme by excessive hydrogen peroxide, as well as glycation of superoxide dismutase molecules or reactions with lipid peroxidation products, the intensity of which increases with age. 3. The negative correlation between superoxide dismutase activity and BMI index indicates reduced enzymatic activity in obese subjects, despite increased ROS production by adipose tissue.

The objective of this study is to determine the possibility of correcting pathological disorders of the oxidative-antioxidant system in the rat organism under the influence of xenobiotics using the flavonoid quercetin, which has an antioxidant, anti-inflammatory, antibacterial, antiviral and immunomodulating effect. Baseline studies have established that when exposed to xenobiotics at a dose of 1/10 and 1/100 DL50, the content of lipid peroxidation products in the serum of rats increases, including 8-isoprostane, TBA-active products (TBA-AP) and diene conjugates (DK). As a result, the state of the antioxidant system also undergoes changes, evidenced by a decrease in catalase activity under the action of xenobiotics in doses of 1/10 and 1/100 DL50, as well as fluctuations in superoxide dismutase content, namely: a decrease under the influence of xenobiotics in a dose of 1/10 DL50 and increase with the action of substances in a dose of 1/100 DL50. After correction with the flavonoid quercetin, a decrease in the content of both primary and secondary POL products in the rat organism, as well as indicators of the state of the oxidative-antioxidant system was established. At the same time, an important for clinical practice relationship was established between the degree of correction of pathological changes in the state of the oxidative-antioxidant system and the dose of toxic effects of xenobiotics. After intragastric administration of “Quertin” in a dose of 25 mg/kg of body weight to rats exposed to polyethylene glycol 400 at a dose of 1/10 DL50, a decrease in serum levels of 8-isoprostan was determined by 14.5%, TBA-AP – by 17.3%, DK – by 15.5%. After exposure to polyethylene glycol 400 at a dose of 1/100 DL50, the content of 8-isoprostane decreased by 12.4%, TBА-AP by 16.8%, and DK by 11.8%. After exposure to polypropylene glycol in doses of 1/10 and 1/100 DL50, the content of 8-isoprostane decreased by 17.7% and 12.5%, TBA-AP – 11.7% and 9.8%, DK – 16.3% and 12.7% respectively. After exposure to ethylene glycol in doses of 1/10 and 1/100 DL50, the content of 8-isoprostane decreased by 22.1% and 14.9%, TBA-AP – 17.3% and 15.2%, DK – 17.6% and 12.2% respectively. Catalase activity increased after the correction by “Quertin” at exposure to polyethylene glycol 400 at doses 1/10 and 1/100 DL50, respectively, by 25.8% and 20.6%; polypropylene glycol – by 26.5% and 23.4%; ethylene glycol – by 19.4% and 15.6%. Superoxide dismutase activity in the blood of rats after the correction of “Quertin” increased at xenobiotic toxification at a dose of 1/10 DL50 (polyethylene glycol 400 – by 29.3%, polypropylene glycol – by 33.5%; ethylene glycol – by 23.2%) and decreased at toxification with xenobiotics at a dose of 1/100 DL50 (polyethylene glycol 400 – by 21.6%, polypropylene glycol – by 26.7%; ethylene glycol – by 18.6%).
