Introduction. One of the major problems characterizing the nutritional status is the iron deficiency, which leads to decreased immunity, increased incidence of infectious diseases and anemia. Obviously, only well-thought-out corrections can solve these disorders.  Material and methods In order to know the influence of the method of manufacture for iron-fortified products on the iron level, a series of in vivo research was carried out, on a batch of 21 white rats, Wistar line, which were induced experimental drug anemia (EDA). The blood analysis was performed in three stages: initially, after the induction of EDA and after the completion of the experiment. Results. Investigations showed out that during sufficient iron intake rehabilitation of the body iron reserve depends considerably on the presence of antinutritive factors. In order to decrease the influence of these factors, the production method used for fortified products with mineral origin micronutrients (iron) could be based on the use of the lactic-acid fermentation procedures using wheat bran.  Conclusions. The research carried out on laboratory animals with induced experimental anemia showed that, in the case of the group fed with bread manufactured by the acid-lactic fermentation method, the concentration of serum,  iron was completely restored during the experiment, and in the rats fed with fortified bread prepared by the traditional method,  the serum iron concentration was only partially restored, 40-45%.

Suspension for injection “Amoxidev 15” is prescribed to fur-bearing animals (mink, fox), dogs and cats for the treatment of respiratory diseases (tonsillitis, tracheitis, pneumonia, bronchitis, rhinitis, sinusitis, bronchopneumonia), digestive (gastritis, enteritis, enteritis). genitourinary systems (nephritis, urethritis, urocystitis, mastitis, metritis, agalactia), musculoskeletal system (arthritis, osteoarthritis, joint injuries, tendonitis, hoof lesions), skin and soft tissues (eczema, dermatitis) caused by sensitive drug by microorganisms, including colibacillosis, streptococcus, bronchopneumonia, etc. Toxicological evaluation of the veterinary drug “Amoxidev 15” under the conditions of acute and subacute toxicological experiments on a model of white rats. According to the results of an acute toxicological experiment with intragastric administration of the drug “Amoxidev 15” white rats DL50 could not be calculated because the death of laboratory animals was not detected within 14 days after administration. The maximum administered dose (in absolute weight of the drug) was 20000.0 mg/kg body weight, which allows to refer the drug to class VI toxicity of relatively harmless substances (DL50 > 15000 mg/kg body weight), and the degree of safety to class IV – low-hazard substances (DL50 > 5000 mg/kg). According to the results of an acute toxicological experiment with subcutaneous administration of the drug “Amoxidev 15” white rats DL50 could not be calculated because the death of laboratory animals was not detected within 14 days after administration, the maximum dose was 5000.0 mg/kg body weight, therefore, the drug “Amoxidev 15” when administered subcutaneously by toxicity can be classified as class VI substances relatively harmless (DL50 Subcut > 4500.0 mg/kg). When administered subcutaneously to white rats, the drug “Amoxidev 15” under conditions of subacute toxicological experiment in doses of 0.1–1.0 ml/kg does not cause hemo-, hepato- and nephrotoxic effects on the body of laboratory animals, although 3-day administration of the drug in a dose 1.0 ml/kg body weight caused an increase in the activity of hepatospecific enzymes ALT and AST by 12.5 and 11.1 % (P < 0.05), respectively, relative to the control, which was restored to the control level 7 days after cessation.

Cancer is a group of diseases in which cells are aggressive, invasive and sometimes metastatic. Nutritional status an important factor that contributes to immune competence for which trace minerals plays a crucial role in the biochemical and physiological activity of the system. Trace element a category of minerals essential for the biological system and plays an active role in immune effector mechanism.  Normal range of iron essential for body metabolism, iron deficiencies leads to anemia which might complicate the event of tumor genesis. Study involved 50 volunteers (36 females, 14 males) of cancer patients of Mohan Nursing Home Madurai. Serum was collected in the informed consent of the patients. Serum iron level was quantified using Atomic Absorption Spectrophotometer. Study documented percentage deviation of serum iron concentration (85%) with severe anemic prevalence from the control individual (without cancer) and also establish an association of iron deficiency with anemic prevalence. Study documented the existence of Iron deficiency which is the most common cause of anemia worldwide. Iron plays a role in oxygen transfer in cytochromes, protein molecules involved in the production of energy in cells and also exhibit certain properties to facilitate antitumor status. Study concludes that serum iron modulations need to be emphasized to minimize the burdenization of the host with Clinical associated complications of Iron deficiency among patients with cancer.

Abstract Background Various types of pulmonary diseases are associated with iron deficiency. However, information on iron status in coronavirus disease 2019 (COVID-19) is scarce. Methods This study included 50 hospitalized patients with confirmed COVID-19. The role of serum iron in predicting severity and mortality of COVID-19 was evaluated. Results The most common symptoms of COVID-19 patients in this study were cough (82%), fever (64%), and chest distress (42%). Of the 50 patients, 45 (90%) patients had abnormally low serum iron levels (&lt;7.8 μmol/L). The severity of COVID-19 was negatively correlated with serum iron levels before and after treatment and was positively correlated with C-reactive protein, serum amyloid A, D-dimer, lactate dehydrogenase, urea nitrogen, and myoglobin levels. Decreased serum iron level could predict the transition of COVID-19 from mild to severe and critical illness. Seven (53.8%) patients with a lower serum iron level after treatment in the critical group had died. There was a significant difference in posttreatment serum iron levels between COVID-19 survivors and nonsurvivors. Conclusions Serum iron deficiency was detected in the patients with COVID-19. The severity and mortality of the disease was closely correlated with serum iron levels. Low serum iron concentration was an independent risk factor for death in COVID-19 patients.

Currently, nephrectomy is performed for various diseases, and the number of this type of surgery does not have a clear tendency to decrease. Operational stress is accompanied by a triggering mechanism for a wide range of disorders, among which psycho-emotional and vegetative (vascular) reactions are important clinical markers. The study of the systemic adaptive reactivity of the body after nephrectomy will provide an integrated approach to the study of the problem of the postoperative period and the rehabilitation of the patient in clinical practice. Objective: to identify the effect of nephrectomy on the overall adaptive response of animals when white rats are exposed to damaging physical loads (acute hyperthermia) and chemical (acute alcohol poisoning, nephrotoxic agents) of nature, normobaric hypoxia, limiting muscular loads and immobilization stress. The results of the experiment showed that laboratory animals with a single kidney become more sensitive (1.5 times) to nephrotoxic agents. Analysis of the effect of nephrectomy on the overall adaptive response of animals under the influence of various damaging factors to reduce the body’s resistance to hypoxia by 20% (p > 0.05); to limit muscular loads – by 25% (p > 0.05); hyperthermia – by 25% (p < 0.05); chemical agents – by one third (p < 0.05); to immobilization stress – by 28% (p < 0.05). Conclusion. The study demonstrated a significant negative impact of nephrectomy on the overall adaptive capacity of the body and allowed to clarify the functional characteristics of the general adaptation disorders in connection with this operation.

Iron is an essential mineral for the human, animal and plant kingdom, being present in water, soil and air. In the organism, iron is found both as a ferrous ion (Fe2+) and as a ferric ion (Fe3+), being involved in oxidoreduction processes and as part of protein structure or in complexes with anions present in cells and tissues. The optimal iron concentration in the body depends on several characteristics (organism type, age, gender, environmental conditions - especially related to altitude, physiological status and others), but there is a rather small variation between the minimum and maximum required concentration -deficiency or excess having a detrimental effect on the organism. In the present work iron gluconate hydrate (10 mg Fe2+/kg body) has been administered intraperitoneally to rabbits, in two separate injections. We formulated a diet rich in plants with protective role, and at the end of the experiment the level of blood serum sodium, potassium, magnesium, ionic calcium, total calcium, iron and chlorine was measured. The results showed that iron overload led to a significant increase of potassium (55.74%), magnesium (31.57%), iron (20.86%) and calcium (with 19.69% total Ca and 17.19% ionic Ca), while the concentration of sodium and chlorine showed non-significant decreases (sodium decreased by 3.83%, and chlorine decreased by 1.58%). Therefore, the excess iron administered over a short period of time to rabbits influences the metabolism of several minerals such as potassium, magnesium, calcium, iron as well as sodium and chlorine and that is reflected in their blood serum level.

Objective: to develop and justify the application of a new experimental method of the simulation of liver cirrhosis in laboratory animals. Material and methods. The simulation of liver cirrhosis was performed on 11 eugamic white Wistar male rats with the body weight of 203.5 ± 22.2 g (experimental group). The control group consisted of 12 healthy laboratory animals. Acute toxic liver injury resulting in cirrhosis was caused by means of the intraperitoneal administration of 50 % solution of carbon tetrachloride (CCl4) in olive oil on the first day of the experiment at a dosage of 0.1 ml of CCl4 + 0.4 ml of olive oil per 100 g of the body weight of the animals, on the second day of the experiment - 0.3 ml of CCl4 + 0.2 ml of olive oil per 100 g of the body weight of the animals. For synergism and potentiation of the hepatotoxic effect of CCl4, the animals daily had free access to 10% ethanol solution. The duration of the experiment was 65 days. The clinical and laboratory parameters were evaluated, the histological assessment of the preparations was carried out. The obtained data were compared with the same parameters of the control group of the animals. Results. The reproducibility of the model was 81.8% (9 animals). The values of the biochemical blood analysis indicated statistically significant increases in the levels of total bilirubin, serum transaminases (AST, ALT), creatinine, a decrease in the glucose level in the animals of the experimental group. The complex morphological confirmation of liver cirrhosis in progress was obtained. Conclusion. The proposed method of the liver cirrhosis modeling correlate with the values of the biochemical blood analysis, pathological changes in the tissue of the liver and internal organs of liver cirrhosis in humans. With the help of the original model, it is possible to investigate the pathogenesis and effects of various groups of pharmacological drugs on liver cirrhosis and its complications (acute blood loss associated with the syndrome of portal hypertension).

Success Of Treatment

Despite significant successes in the development of medical sciences, the study of oncopathology issues still occupies a leading place due to the identification of a large number of advanced cases of the disease. Firstly, this may be due to the rapid growth of a malignant tumor, for example, against the background of immunodeficiency. Secondly, with late treatment of patients, when they already have distant metastases. The success of treatment of any oncological process primarily depends on the timing of the diagnosis: the earlier the tumor is diagnosed, the greater the chance of a positive outcome and an increase in the life expectancy of the cancer patient. The most formidable complication of oncopathology and the main cause of death from it is metastasis, which often reduces to zero all the effects of therapy. Metastasis remains a mystery today. So, despite the large number of various theories, the question of the spread of the tumor throughout the body has not yet been resolved. There is no definite answer to the question: do metastases metastasize? The mechanisms of the influence of hormones on the processes of metastasis have not been fully studied. Difficulties in diagnosis are associated with the lack of clinical manifestations before the appearance of metastases, the inability to track and compare changes in tissues and organs in vivo, the non-specificity of the results of available research methods, and the lack of control of the spread of metastases throughout the body. Experimental studies on laboratory animals can provide answers to these and many other questions. In a review of the literature, a study of the main issues of metastasis is conducted.

Early Diagnose

Coronavirus disease emerged in Wuhan, China in December 2019 and led to worldwide pandemic in March 2020. Due to early diagnose, treatment and prevent transmission of COVID-19 disease, we need rapid laboratory tests and develop them. This paper focuses on serum Iron level in patients with COVID-19. We assess the serum Iron level due to the following reasons: I. Iron is a key part of hemoglobin structure in which is essential for providing Oxygen to the body organs, particularly for the patients with pulmonary involvement such as COVID-19. II. Iron deficiency can contribute to muscle weakness and reduction of respiratory capacity, at which increases the risk of deterioration of COVID-19 patients. III. Elevation in Hepcidin level (due to the increase in IL-6 level) in COVID-19 patients inhibits Iron absorption from intestinal lumen and blocks the Iron release from macrophages. IV. Iron is an essential element in infectious suppress and inflammatory process. We noticed that most of the patients, especially admitted to hospital due to the respiratory symptoms, have lower serum Iron level.

This study aimed to assess the state of haemostasis at supplementation of the diet with vitamins and the possibility of correcting changes in coagulation under combined thermal effects on the body of laboratory animals (white rats). The animals were kept on a nutritious diet with sufficient intake of proteins, fats, carbohydrates and trace elements. As part of daily servings in addition to the diet, the experimental group received vitamins A, E, B6, B9, B12 and P in therapeutic doses adequate to those recommended for humans; the control group did not receive vitamins. After 14 days, part of the animals from both groups were subjected to combined thermal stress. At all painful manipulations the animals were anesthetized with ethoxyethane. Blood samples were taken in a syringe from the jugular vein exposed by an ovalshaped incision immediately after stress exposure. For coagulation testing, blood was stabilized with a 3.8 % sodium citrate solution in a ratio of 1 to 9. Subsequent blood treatment met the requirements accepted for coagulation testing. The following haemostatic parameters were studied: platelet count, activated partial thromboplastin time, prothrombin time, thrombin time, antithrombin III activity, as well as content of fibrinogen and soluble fibrin monomer complexes. The obtained results showed that the combined thermal effect causes a significant acceleration of continuous blood coagulation (consumption thrombocytopenia, hypofibrinogenaemia and mismatch of clotting test parameters) in rats. Additional vitaminization restrains the severity of these changes, which is manifested in the absence of platelet consumption, a decrease in the consumption of plasma coagulation factors and the preservation of a high antithrombin potential.

The attempts to demonstrate the virus of hog-cholera in rabbits 12 days after intravenous and intraabdominal inoculations were unsuccessful. Likewise the attempts to show that the virus might be found in the guinea pig 6 and in the pigeon 7 days after inoculation were negative. It was shown, however, that the virus can be found in the bodies of white rats for at least 7 days after either intraabdominal or intracerebral inoculations. One attempt to demonstrate it after 10 days was negative. From the fact that the rats show no evidence of illness such as loss in weight, pyrexia, or visible pathological changes, and that after either intraabdominal or intracerebral inoculation the virus is only found in the abdominal organs and possibly only in the spleen, it seems likely that it does not multiply but that in the rat tissue, particularly in the spleen, it is not destroyed so rapidly as in the organs of other animals. Careful study of the records fails to show that passing one strain of virus alternately through pigs and rats for three transfers in each species changes the virulence for swine or causes the virus to become virulent for rats. Attempts to introduce the virus into the body of the rat by feeding virulent material and an attempt to pass the virus from one lot of rats to another were unsuccessful, so that we have evidence from the experiment that the rat does not play a part in the transmission of hog-cholera.
