Methodological Approaches

The purpose of this research was to study the possibility of using of food products from a mixture of Hypericum perforatum (HP) and Rhodiola rosea (RR) for the stimulation of the body´s compensatory responses to the conditions of high and low temperatures. Experiments have been conducted on experimental animals (150 white mongrel rats) in accordance with generally accepted methodological approaches. Antioxidant effects in the organism of white rats have been studied at the initiation of the processes of lipid peroxidation by the introduction of carbon tetrachloride. We were determined the products of lipid peroxidation (diene conjugates, hydroperoxides of lipids, malonic dialdehyde) for the evaluation of antioxidant effect in accordance with generally accepted methodological approaches. Researches of cold and heat adaptation reactions of experimental animals have been conducted by using the model of a long cold and heat action with appropriate climatic chambers. It was established experimentally that in doses of 150-300 mg/kg daily of the studied mixture has a strong antioxidant effect in the conditions of cold and heat stress on warm-blooded organism. The research allows to recommend a mixture of HP and RR as а regulator of adaptive reactions of the organism when exposed to low and high temperatures.

The purpose of the work is to study the processes of free radical lipid peroxidation, antioxidant system activity and their connection with the iron metabolism in white rats with experimental hepatitis, and after the use of hepatoprotectors. Materials and Methods. Studies were conducted on white Wistar rats: body weight – 180–200 g, age – 3 months. “Berlition” and “Legalon M” were administered intramuscularly, 0.2 ml per animal once a day (30 days). The authors registered the content of malonic dialdehyde (MDA), diene conjugates, catalase activity, serum iron level, total and unsaturated iron binding capacity. Results. In experimental animals, the level of diene conjugates increased 1.8 times if compared with healthy ones. After the administration of “Legalon M” and “Berlition”, the concentration of diene conjugates decreased by 58.6 % (by half) compared with the experimental animals. It was established that the malondialdehyde content significantly increased in all tissues. After the administration of “Legalon M” and “Berlition”, the malondialdehyde content decreased in the liver, lungs and muscle tissues. In the tissues of the intestine and in the blood serum, MDA level resolved to that of healthy animals. In experimental animals, catalase activity increased significantly if compared with healthy ones. After “Legalon M” and “Berlition” administration there was a decrease in enzyme activity in all body tissues. In animals with experimental hepatitis, there was a failure of iron metabolism in the body. The authors observed activation of iron metabolism in the body after drug administration to rats with experimental hepatitis. Conclusions. “Ligalon M” and “Berlition” have an antioxidant effect and stimulate iron metabolism.

Introduction One of the reasons for the lack of quality drinking water is the poor quality of natural water, which is constantly polluted by waste water from industrial and municipal enterprises, surface runoff from the fields and territories of settlements with which it enters a large amount of toxic substances. Among them, surface-active substances such as potassium and sodium stearate are not the last.The aim of the study to determine the specifics of lipid peroxidation and the state of the antioxidant protection under the influence of potassium and sodium stearates on the body of the experimental rats when they enter with drinking water.Research Methods. White rats were divided into 7 groups, which consumed water with stearates in quantities equal to the maximum non-active dose of the substance (MND), 1/2 MND and 1/4 MND for 25 days. The content of TBC-active lipid peroxidation products, diene conjugates and the activity of superoxide dismutase and catalase in liver homogenate were determined.Results and Discussion. In the homogenate of the liver of animals of all groups, there was a significant increase in the level of diene conjugates and TBK-active products in proportion to the concentration of the substance. It was also found that in animals that consumed water with different concentrations of potassium stearate, inhibition of antioxidant enzymes was observed. Consumption of water with different concentrations of sodium stearate caused the activation of these enzymes.Conclusions. Prolonged use by test animals of aqueous solution with  concentrations of potassium and sodium stearate in MND and 1/2 MND negatively affects the state of hepatocyte cell membranes due to the activation of the lipid peroxidation processes, namely TBK-active products and diene conjugates, the amount of which depended on the concentration of stearates in drinking water. The use of drinking water by test animals with maintenance of potassium and sodium stearates at various doses caused changes in the content of antioxidant enzymes: water with potassium stearate inhibits the activity of these indicators, and causes sodium activation with sodium stearate.

The aim is to study the dynamics of lipid peroxidation and antioxidant protection in the blood of patients with generalized periodontitis accompanied by normo-, hyper- and hyporeactivity of the body after patch surgery. Materials and methods: 216 people aged 45 between 55 years with a diagnosis of generalized periodontitis of II, III degree of severity, chronic course were examined. Depending on the condition of reactivity of the organism, patients were divided into three groups: the first consisted of people with normoreaction; the second included patients with hyperreaction; the third group was made up by people with hyporeaction. Patients after initial therapy, underwent patch surgery. Blood sampling was performed after surgery on the 1st, 2nd, 4th, 6th and 9th day. The content of diene conjugates, malonic dialdehyde and peroxide hemolysis of erythrocytes, superoxide dismutase activity, catalase, and total antioxidant activity was determined by the biochemical method. Results: Normoreaction was characterized by two-phase moderate activation of lipid peroxidation with maxima on the 1st and 6th day against the normalization of the balance of oxidative systems by the end of observations. For hyperreaction pronounced activation of lipid peroxidation (significant increase in the content of diene conjugates and malonic dialdehyde with a maximum on the 1st day) accompanied by depletion of antioxidant protection activity was typical. Hyporeaction was characterized by slow activation of lipid peroxidation (increase in diene conjugates and malonic dialdehyde with a maximum on the 4th day) accompanied by insufficient activity of antioxidant protection. Conclusion: Correction of altered parameters in patients with generalized periodontitis accompanied by impaired (hyper- and hypo-) reactivity of the body with bringing them to values of normoreactivity is considered to be a condition for optimizing mucosal wound healing after surgery and further stabilization of the periodontal tissues.

Endogenous hyperthermia was induced in rabbits by i.v. pyrogenal administration. Hemoglobin-oxygen affinity and parameters of free radical lipid oxidation in plasma and red blood cells were measured. The content of diene conjugates, malonic dialdehyde and Schiff bases were determined at a pyrogenal dose of 4 minimal pyrogenic doses/kg, and iron-initiated chemiluminescence, catalase activity and alpha-tocopherol concentration were determined at 6 minimal pyrogenic doses/kg. A rightward shift of the real oxyhemoglobin dissociation curve and activation of lipid peroxidation were observed. Relationships between the parameters measured were analyzed. Decreased hemoglobin-oxygen affinity is considered to be a possible mechanism of activation of free radicals during fever.

Introduction. Historically, pesticides are evaluated more strictly from a medical point of view than other chemicals. Since their features, such as deliberate introduction into the environment, the possibility of contact with them by large masses of the population, and the high biological activity determine their potential danger to humans. Purpose of research - study of the biological effect of a technical product derived from triazoles when it is repeatedly ingested orally in mammals (rats), establishment of inactive and active doses, justification of the permissible daily dose (DSD) for humans. Material and methods. In acute experiments, white rats were used, including 6 animals in the group. Tested dose: 500-4000 mg/kg of body weight. A chronic (12 months) experiment was performed on 80 male rats with a bodyweight of 180-190 g at the beginning of the study. Tested doses: 5.0; 16.0 and 55.0 mg/kg of body weight (1 control and 3 experimental animals, 20 individuals each). In the dynamics of the experiment, we observed the condition and behavior of animals, water, and food consumption, recorded the timing of death, changes in body weight, physiological, biochemical, and hematological indices. Results. Indices of the acute oral toxicity on the studied product LD50 male rats were 2250 ± 483 mg/kg body weight. The dose of 5.0 mg / kg of body weight was not found to cause significant changes in all studied indices. The doses of 16.0 and 55.0 mg/kg of body weight had a polytropic effect on the body in experimental animals. Discussion. The studied product for the acute oral toxicity refers to low-hazard compounds, the doses of 16.0 and 55.0 mg/kg of body weight has a polytropic effect on the mammalian body, causing changes in carbohydrate, lipid, and lipoprotein metabolism in the body of rats - was accepted as acting. The dose of 5.0 mg / kg of body weight, when administered in rats, there are no changes in all the studied parameters throughout the experiment, is accepted as invalid. Based on the inactive dose-5.0 mg/kg of body weight and taking into account the reserve factor of 100, we have scientifically justified DSD for a person at the level of 0.05 mg/kg. Summary. The conducted sanitary and Toxicological studies indicate the need to assess the toxicity of new technical products to the mammalian body, to increase the reliability of the developed hygiene standards in environmental objects and food products.

Introduction. Given the significant prevalence of lead in the environment, research in this area has significant social and economic importance. Lead compounds are characterized by high toxicity and increased ability to cumulate in ecosystems, humans, and animals. Lead enters the human body with food, drinking water, atmospheric air, and smoking. Lead causes pathological changes in the nervous system, blood-forming organs, kidneys, etc. Materials and methods. The experiments were carried out on four groups of white female rats, each included seven animals, weighing 150-200 g. The first group of animals was a control. The second group consumed dechlorinated water from the city water supply, followed by lead acetate. The animals from the third and fourth groups drank the same water with sodium stearate and potassium stearate content in a dose of 1/250 LD50. After the 40th-day of the use of these waters, the animals were orally administered lead acetate at a dose of 7 mg/kg. The levels of lipid peroxidation biomarkers were studied by studying the content of diene conjugates (DC) and malondialdehyde (MDA) in blood serum, liver, and kidney homogenates. Results. The administration of 1/2 acetate LD50 to lead in experimental rats drinking water with stearates was accompanied by a significant increase in the DCs concentration and (MDA) in animals. Higher concentrations of LPO products were observed in the group of animals that consumed water from potassium stearate. Conclusions. 1. With the oral administration of lead acetate against the background of drinking water containing stearates at a dose of 1/250 LD50, an increase in lipid peroxidation indices was noted compared with the control group. 2. Higher concentrations of LPO products were observed in the group of animals consuming water from potassium stearate.
