Background. The imbalance of innate defense early mechanisms in children from pathogens — peroxidation and antioxidant system, can lead to a decrease in the efficiency of the entire immune system. The study of the lipid peroxidation (LPO) and antioxidant protection (AOP) status in children with recurrent acute respiratory diseases will complement the scientific data on the antimicrobial immunity formation processes. The study was aimed to increase the information value of timely detected pro- and antioxidant processes disorders in children with recurrent acute respiratory diseases by studying the primary, secondary, tertiary, and quaternary compounds of LPO and AOP in the serum. Materials and methods. Sixty children aged from 2 to 5 years were examined. Two groups were formed: group 1 — children with respiratory acute infectious more than six times per year (n = 30); group 2 — children with respiratory acute infectious six or fewer times per year (n = 30). Results. The children in group 1 more often presented with high serum levels of lipid hydroperoxides (by 80.0 %; p < 0.05), diene conjugates (by 80.0 %; p < 0.05), malonic dialdehyde (76.7 %; p < 0.05), diene ketones (76.7 %; p < 0.05), Schiff bases (76.7 %; p < 0.05). ceruloplasmin (80.0 %; p < 0.05), superoxide dismutase (80.0 %; p < 0.05), glutathione peroxidase (86.7 %; p < 0.05), catalase activity (86.7 %; p < 0.05). The values of retinol, tocopherol, ascorbic acid in children in the observation groups did not differ statistically significantly. Conclusions. The children aged from 2 to 5 years old with recurrent acute respiratory diseases have an imbalance of the LPO and AOP systems. It was characterized by a simultaneous increase in the serum content of the primary, secondary, and end-products of LPO, enzymes of anti-peroxide and anti-oxygen protection against the background of the lack of adaptive increase in the content of anti-radical compounds.

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.

Modern environmental conditions dramatically increased the level of radical forming processes in the body. Heat exposure stimulates the generation of reactive oxygen species inducing peroxidation of lipids as a result of the development of hypoxia. In experimental conditions the possibility to correct free radical lipid oxidation of rats’ organism membranes was studied with the oral introduction of the phytoadaptogens that contain the complex of natural antioxidants. The animals were divided into 5 groups and each of them had 30 rats: intact animals (1) which were held in standard conditions of vivarium; the control group (2) in which rats were exposed to heat during forty-five minutes daily; the experimental groups (3, 4, 5) in which before the effects of heat animals had a daily oral intake of the extracts of Eleutherococcus, Rhodiola, liquorice in a dose of 1 ml/kg. It was found out that in the liver tissue of experimental animals a daily heat exposure during forty-five minutes contributes to the increase of lipid hydroperoxides level (by 34-41%), of diene conjugate (by 45-50%), and of malonic dialdehyde (by 62-74%) against the decrease of antioxidant system activity in the liver of intact animals. The introduction of phytoadaptogens to rats in the conditions of heat exposure contributes to the reliable decrease in the liver of lipid hydroperoxides by 22-28%, of diene conjugates by 22-32%, and of malonic dialdehyde by 30-37% in comparison with the rats of the control group. While analyzing the effect of the phytoadaptogens on the activity of the components of antioxidant system it was shown that the level of ceruloplasmin in the liver of animals was reliably higher by 68-82%, of vitamin E by 42-65% in comparison with the same parameters of the rats of the control group. So, the application of phytoadaptogens in the conditions of long heat exposure of the organism of animals under experiment leads to the stabilization of the processes of peroxidation against the increase of antioxidant system activity.

Currently there is an active search for medicines increasing the stability of liver to pathological effects, reinforcing its neutralizing function, promoting its functional recovery after various injuries, including poisoning by industrial poisons. Therefore, the study of opportunities to reduce toxic liver damage by carbon tetrachloride introduction of synthetic and natural antioxidants is of interest. In experimental conditions the possibility to correct free radical lipid oxidation of rats’ organism membranes was studied with the introduction of the succinate containing drug called Reamberin (Polysan, St.Petersburg) and licorice syrup. The animals were divided into 4 groups and each of them had 10 rats: the group with intact animals which were held in standard conditions of vivarium; the control group in which rats were given carbon tetrachloride during 3 days daily; the experimental group in which before the introduction of carbon tetrachloride animals had a daily intra-abdominal intake of the Reamberin in a dose of 100 mg/kg (20 ml/kg); the experimental group in which before the introduction of carbon tetrachloride animals had a daily oral intake of the licorice syrup in a dose of 5 ml/kg. It was found out that in the blood and in the liver of experimental animals an introduction of carbon tetrachloride during 3 days contributes to the increase of lipid hydroperoxides level (by 24-43%), of diene conjugate (by 19-47%), and of malonic dialdehyde (by 61-81%) against the decrease of antioxidant system activity in the blood of intact animals. The introduction of the succinate containing drug to rats in the conditions of oxidative stress contributes to the decrease in the blood and in the liver of lipid hydroperoxides by 13-26%, of diene conjugates by 11-28%, and of malonic dialdehyde by 30-34% in comparison with the rats of the control group. Adding of the licorice syrup to rats contributes to the reliable decrease in the blood and in the liver of lipid hydroperoxides by 6-23%, of diene conjugates by 9-24%, and of malonic dialdehyde by 25-30% in comparison with the rats of the control group. While analyzing the effect of the antioxidants on the activity of the components of antioxidant system it was shown that the level of ceruloplasmin in the blood and in the liver of animals was reliably higher by 10-47%, of vitamin E by 13-42% in comparison with the same parameters of the rats of the control group. So, the application of the synthetic and natural antioxidants in the conditions of introduction of carbon tetrachloride of the organism of animals under experiment leads to the stabilization of the processes of peroxidation against the increase of antioxidant system activity.

The search and development of methods for correction of oxidative stress in conditions of exposure to adverse environmental factors is an actual problem of modern medicine. In experimental conditions the possibility to correct free radical lipid oxidation of rats’ organism membranes was studied with the introduction of the succinic acid and of the succinate containing medication called Reamberin (Polysan, St. Petersburg). The animals were divided into 4 groups and each of them had 20 rats: the group with intact animals which were held in standard conditions of vivarium; the control group in which rats were exposed to ultraviolet radiation during three minutes daily; the experimental group in which before ultraviolet radiation animals had a daily intraabdominal intake of the succinic acid in a dose of 100 mg/kg; the experimental group in which before ultraviolet radiation animals had a daily intraabdominal intake of Reamberin in a dose of 100 mg/kg (20 ml/kg). It was found out that in the blood of experimental animals a daily ultraviolet radiation during three minutes contributes to the increase of lipid hydroperoxides level (by 48-53%), of diene conjugate (by 43-48%), and of malonic dialdehyde (by 48-61%) against the decrease of antioxidant system activity in the blood of intact animals. The introduction of the succinic acid to rats contributes to the significant decrease in the blood of lipid hydroperoxides by 15-16%, of diene conjugates by 9-16%, and of malonic dialdehyde by 15% in comparison with the rats of the control group. The introduction of the succinate containing Reamberin to rats in the conditions of oxidative stress contributes to the significant decrease of lipid hydroperoxides in the blood by 27-28%, of diene conjugates by 23-28%, and of malonic dialdehyde by 26-29% in comparison with the rats of the control group. While analyzing the effect of the succinate containing drugs on the activity of the components of antioxidant system it was shown that the level of ceruloplasmin in the blood of animals was significantly higher by 25-32%, of vitamin E by 28-33% in comparison with the rats of the control group. So, the application of the succinate containing antioxidants in the conditions of ultraviolet radiation under experiment leads to the stabilization of the processes of peroxidation against the increase of antioxidant system activity. The intraabdominal introduction in laboratory animals of Reamberin in a dose of 100 mg/kg of succinate prevents the accumulation of lipoperoxidation products and increases the activity of main components of the antioxidant system in rats’ blood plasma, which indirectly exceeds similar effect of succinic acid in a dose of 100 mg/kg in the conditions of oxidative stress.

Stimulation Of

The widespread worldwide spread of acute respiratory diseases is an urgent problem in health care. Expressed polyetiology of respiratory diseases does not allow to limit the use of specific vaccine preparations and dictates the need to use to combat them a variety of non-specific means that stimulate the natural resistance of the human body. The main pharmacological action of sodium deoxyribonucleate is the stimulation of phagocytic activity of T-helpers and T-killers, increasing the functional activity of neutrophils and monocytes/ macrophages, providing regeneration and repair processes in the epithelial component of antiviral protection of the body. Based on the above, the study of the clinical efficacy of Derinat® in the form of spray in the treatment of acute respiratory viral infections is relevant.

Cysteine, methionine, vitamin A, β-carotene and glutathione (GSH) are known to protect body tissues against oxidative damage and inflammation but their value as protection against liver inflammation in tropical areas has received little attention. Blood levels of these nutrients were measured in Ghanaian volunteers with (Group 2) or without (Group 1) increased lipid peroxidation and signs of liver inflammation, as indicated by blood malonic dialdehyde, serum α1-antitrypsin and triglyceride levels, and the α1-acid glycoprotein: pre-albumin ratio. Serum levels of cysteine and blood glutathione were significantly lower ( P < 0.02) in group 2 than in group 1 volunteers. In contrast, serum levels of methionine, vitamin A and β-carotene were similar in both groups. Deficits in cysteine and glutathione may increase the risk of liver toxicity from oxidants in Ghanaians.

The activation of the kinin system of the blood in diseases of the respiratory system leads to an increase in the inflammatory response in the respiratory tract, causes bronchospasm to a large extent, and has an inhibitory effect on the function of the ciliated epithelium. There are no unequivocal judgments about the therapeutic effect of prednisolone in obstructive bronchitis and bronchiolitis in the literature. There is a negative answer to this question. At the same time, the beneficial effect of corticosteroids on pulmonary mechanics in bronchiolitis was noted.
