(1) Background: Well-known monosodium glutamate (E-621, MSG), originally used as a food flavor enhancer, was approved approximately in all countries, but the toxicity versus the safety of (MSG) are still unclear due to variable scientific toxicological reports. Moreover, it was reported to trigger elevated frequencies of nausea and headaches in humans and provide deleterious effects on laboratory animals. The objectives of the present study were to (i) estimate the possible toxic effects of the food additive MSG (ii) and the ameliorating protective effects of the dietary supplement spirulina (Spirulina platensis) on the biochemical parameters of blood and the damage produced in organs of Swiss mice after applying a supplementary daily dose of MSG for 4 weeks. (2) Methods: The present study was conducted on 20 mature Swiss mice, which were randomly organized into four groups of five Swiss mice. The treatments were (I) the control group, in which Swiss mice were fed only animal feed and drinking water; group II MSG1, which received 1 mL of MSG; group III MSG0.5, which was treated with 0.5 mL of MSG; and (IV) the group MSGS, which was treated with 1 mL of monosodium glutamate and 1 mL of spirulina (aiming to reduce the MSG toxicity). (3) Results: At the end of the experiment, Swiss mice treated with MSG demonstrated a passiveness regarding behavioral aspects. As we hypothesized, the parameters of the spirulina group reached similar values to the control group, and no histopathological observations have been found. Altogether, our findings evidenced that monosodium glutamate leads to histopathological changes in Swiss mice kidneys and caused important modifications for all biochemical parameters of the blood serum. Noticeably, the potential protective effect of Spirulina platensis was proved and was described by using the FTIR spectroscopy technique. (4) Conclusions: A diet rich in antioxidants and other plant-derived bioactive compounds may provide healthy nutrition, alleviating the potential side effects of some food additives.

Изучена целесообразность использования в рационах телят черно-пестрой породы комплексной минерально-витаминной кормовой добавки (КМВКД). Установлено пониженное содержание в кормах таких элементов, как кальций, фосфор, магний, сера, марганец, медь, цинк и кобальт. Соотношение питательных и минеральных веществ, степень их доступности для усвоения организмом не обеспечивают их потребность. Использование КМВКД способствовало улучшению всех гематологических показателей. Все испытываемые рецепты, имеющие в своем составе разные варианты макро-, микроэлементов и витаминов положительно влияют на обменные про- цессы в организме животных. У молодняка опытной группы, получавшей подкормку по рецепту 1, количество эритроцитов в сравнении с животными контрольной группы увеличилось на 6,6, гемоглобина на 6,93 соответственно, по рецепту 2 11,05 и 11,39 по рецепту 3 16,75 и 15,27, то есть соотношение макро- и микроэлементов, имеющихся в составе КМВКД и взаимодействие между собой меди, железа и кобальта сыграли особую роль на концентрацию форменных элементов. У молодняка, получавшего подкормку по рецепту 1 количество общего белка в сравнении с животными контрольной группы увеличилось на 1,99, кальция на 16,02, каротина на 10,92 соответственно, по рецепту 2 4,91, 25,96 и 19,12 по рецепту 3 на 3,58, 27,07 и 20,21. Значительное повышение содержания белка, кальция, фосфора и каротина по сравнению с животными контрольной группы объясняется тем, что недостаток их в рационах восполнялся за счет используемой подкормки, в результате их содержание увеличилось в сыворотке, но не выходило за пределы нормативных данных и соответствовало физиологическим нормам.Practicability of using a complex mineral and vitamin feed additive (CMVFA) in the ration of black-and-white calf breed was studied. Decreased content of such elements as calcium, phosphorus, magnesium, sulfur, manganese, copper, zinc, and cobalt was registered. The correlation of nutritive and mineral substances, and the level of their availability for digestion did not provide for their need. CMVFA use facilitated the increase of all hematologic parameters. Tested recipes which had different content of sapropel and zeolite, as well as various types of macronutrients, microelements, and vitamins, positively influenced the digestive processes in animal bodies. Young stock from the test group that was receiving food additives according to recipe No. 1 showed 6.6 increase in the quantity of red blood cells compared to control group animals, and 6.93 increase in hemoglobin quantity the ones who were fed according to recipe No. 2 demonstrated the increase by 11.05 and 11.39 recipe No. 3 showed 16.75 and 15.27 increase, which means that the ratio of macronutrients and microelements present in CMVFA and the mutual interaction of copper, iron, and cobalt played a special role in the concentration of formed elements due to the fact that they are integral elements of blood. Total protein of young stock that was receiving food additives according to recipe No. 1 was 1.99 higher than in test group animals calcium 16.02 higher carotene 10.92 as for recipe No. 2 the values were increased by 4.91, 25.96, and 19.12 recipe No. 3 3.58, 27.07, and 20.21. Substantial increase in the content of protein, calcium, phosphorus, and carotene compared to control group animals can be explained by the fact that their insufficiency in animal feed was replenished due to the use of feed additives, and as a result their content increased in the serum but did not go beyond the norm and corresponded to physiological norms.

The Impact

Herbicides and food additives are included in many food products for humans. Non-used products or products beyond their expiry date are deposited in places of utilizatioin of solid municipal wastes, where they can take effects on the organisms of mouse-like rodents. Among the herbicides, glyphosphate takes first place in the world for volume of production, and is the most intensely used in agricultural farming. The discussion about negative impact on the organisms of mammals, especially against the background of using various substances and environmental factors, continues. In this study, we determined the combined effect of glyphosphate and food additives on the organism of laboratory animals, which manifested in changes in body weight, condition and indices of mass of the internal organs and blood parameters. Four groups of laboratory male rats were formed, which over 42 days received: unlimited access to clean water; 1% aqueous solution of glyphosate; 1% solution of glyphosphate and 1% solution sodium benzoate; 1% solution of glyphosphate with 1% solution of saccharin. Glyphosphate and glyphosphate with sodium benzoate and saccharin significantly reduced the daily increases in body weight of animals compared to the control group. The studied substances have notable suppressive effect on the immune system and haematopoiesis in general, which is manifested in reduce of relative mass of the thymus and spleen against the background of increase in the amount of lymphocytes in the peripheral blood. The inhibition of haematopoiesis is indicated by decrease in the amount of erythrocytes, neurophils and hemoglobin of blood of animals from the experimental groups. The impact on the digestive system of glyphosphate and food additives is indicated by occurance of the effect of “irritation” of mucous membranes, and, as a result, disorders in absorption followed by the disorder in metabolic processes. A dysbalance occurs in enzymic systems of the organism, which is manifested in distrophic processes, especially in the liver parenchyma, indicated by the activity of blood enzymes (ALT, AST, alkaline phosphatase), total number and ratio of proteins of blood plasma. We determined the impact of glyphosphate and its mixes with benzoate and saccharin on the pancreas, which manifests in severe pancreatitis with steep increase in the level of glucose of blood. The results of the study allow us to state that mixture of glyphosphate and food additives can cause toxic effect in animals and humans, which often contact with herbicides.

The present study investigated the unsafe impacts of sodium nitrite, sodium benzoate and their mixture which is utilized in fabricating of the food on some biochemical parameters in male albino rats. Rats (40) were divided into four groups as follows: group 1 used as the control, group II and III were treated orally with sodium nitrite nano2 (80 mg/kg BW) and sodium benzoate (SB) (200 mg/kg BW), respectively. Group IV was treated orally with a mixture of sodium nitrite and sodium benzoate. Rats took their respective doses every day for 8 weeks. The obtained results showed that sodium nitrite, sodium benzoate and their mixture (nano2 and SB)  initiated a diminished within in the activity of antioxidant enzymes (SOD, CAT, and GSH) within the kidney, while, MDA recorded a highly significant activity level within experimental groups. Urea and creatinine mean levels were were expanded within plasma of the experimental rats. In the histology of the kidney, sections appeared edema with few mononuclear leukocyte cellular infiltrations, shrinkage of glomeruli. The severity of these changes increased in the experimental group which treated by the mixture of sodium nitrite and sodium benzoate. Overexpression in p53 occurred in experimental groups that were treated by nano2, SB and their mixture. The present study concluded that the mixture of food additives can induce toxicity in the kidney of rats. It is obvious that food additives induced nephrotoxicity  within the kidney. It decreased the antioxidant enzymes (GSH, CAT, and SOD) and increased MDA. Increase tumor suppressor gene p53 in kidney tissue. Food added substances caused changes in biochemical parameters as in creatinine and urea. The utilization of food additives must be decreased. The presence of more than one type of food additives on our food and the usage of the mixture of sodium nitrite and sodium benzoate initiated changes in biochemical parameters and immune-histopathological changes.

Background. Active smoking and exposure to passive smoke are responsible for more than 5 million deaths each year. At the same time, a characteristic feature of present food technologies is the use of food additives that are not always safe for human health, such as monosodium glutamate (MSG). Objective. The aim of the research was to determine the changes in mitochondrial enzymes activity in rats in case of passive tobacco smoke combined with prolonged administration of MSG in the sex and age aspects. Methods. The evaluation of bioenergetics processes in the mitochondria of circulating neutrophils was carried out using succinate dehydrogenase (SDG) and cytochrome oxidase (CO) activity.  Results. Passive tobacco smoke combined with the MSG administration in mature male-rats is accompanied by a significant inhibition of bioenergetics processes, as evidenced by a decrease in succinate dehydrogenase activity by 47.1% (p<0.001) compared to the intact animals, which is by 27.9% (p<0.001) below this index in case of the isolated effect of tobacco smoke and reduction of cytochrome oxidase activity by 27.5% (p<0.001) compared to the control group. Conclusions. Thus, the findings suggest that low dose intake of monosodium glutamate enhances the ability of tobacco smoke to disrupt the cell's bioenergetics processes by affecting the respiratory chain function and generation of ATP. Therefore, it is advisable to investigate the established toxic doses of E621, as well as to study the molecular mechanisms of the ‘safe’ (allowed) doses of MSG effect on a living organism.

We investigated the protective effects of resveratrol on hematological and biochemical changes induced by fluoride in rats. A total of 28 rats were divided into 4 groups: control, resveratrol, fluoride, and fluoride/resveratrol(n=7each), for a total of 21 days of treatment. Blood samples were taken and hematological and biochemical parameters were measured. Compared to the control group, the fluoride-treated group showed significant differences in several hematological parameters, including decreases in WBC, RBC, and PLT counts and neutrophil ratio. The group that received resveratrol alone showed a decrease in WBC count compared to the control group. Furthermore, in comparison to the control group, the fluoride group showed significantly increased ALT enzyme activity and decreased inorganic phosphorus level. The hematological and biochemical parameters in the fluoride + resveratrol treated group were similar to control group. In the fluoride + resveratrol group, resveratrol restored the changes observed following fluoride treatment, including decreased counts of WBC, RBC, and PLT, decreased neutrophil ratio and inorganic phosphorus levels, and elevated ALT enzyme activity. The present study showed that fluoride caused adverse effects in rats and that resveratrol reduced hematological and biochemical alterations produced by fluoride exposure.

Common food additives endorsed by Food and drug Organization "FDA" are utilized to preserve taste. The display think about examined the perilous impacts of sodium nitrite, sodium benzoate and their blend which utilized in fabricating of the food additives on a few biochemical parameters and  histo-pathological examination in male rats. Male rats were divided into four groups; group I utilized as control, group II and III were treated orally with sodium nitrite NaNO2 (80 mg/kg BW) and sodium benzoate (SB) (200 mg/kg BW), separately. Group IV was treated orally with the blend of sodium nitrite and sodium benzoate. Rats were managed their dosages each day for 8 weeks. It appeared that sodium nitrite, sodium benzoate and their blend (NaNO2 and SB) initiated a critical increment within the serum levels of aspartate aminotransferase "AST", alanine aminotransferase "ALT". Antioxidant proteins (GSH, CAT) within the liver tissue recorded a decrease while, MDA recorded an increase action level within the tested groups. Over expression in p53 happened in exploratory groups which were treated by NaNO2, SB and their blend. The present study concluded that the blend of food additives can actuate harmfulness within the liver of rats. In conclusion, it is noted that food additives induced hepatotoxicity within the liver. It diminished the antioxidant chemicals (GSH, CAT) and elevated the activity level of the MDA and increment tumor silencer quality p53 in liver tissue. Food additive substances caused changes in biochemical parameters (ALT, AST). The utilization of food additives must be diminished. The usage of the mixture of sodium nitrite and sodium benzoate induced changes in biochemical parameters and immune-histopathology.

The aim is to form a balanced position regarding the ergogenic characteristics of new sports food products in the modern practice of training highly qualified athletes on the basis of clinical-experimental evaluation of the effectiveness of special purpose real food additives. Materials and methods. Studies were carried out on laboratory animals (36 Wistar rats at the age of 3 months weighing 150–200 g and 16 Svetlogorsk mini-pigs) as well as on 102 high-qualified representatives of cyclic sports (all men aged 19–26) − members of national teams such as swimming (25), cross-country athletics (53), and skiing (24). As a control group, we studied 25 athletes of the same gender (all men), age and qualifications who received a placebo (starch capsules) for a long time during exercise. Placebo-controlled studies have been conducted on laboratory animals and athletes in compliance with the principles of bioethics. Results. It has been established that in the experiment the application of a new specialized food product MioActiv has a positive effect on the physical performance of animals and delays the onset of fatigue, which significantly exceeds the corresponding characteristics in the placebo group. Athletes also showed an increase in speed when passing competitive distances by 18.7–21.4% (p &lt; 0,05), as well as a significant increase in mental endurance indicators (p &lt; 0,05). The approbation of the innovative pre-workout pharmacological nutrient complex Pre-Fuse also showed the high efficacy and safety of this product with a positive effect of increasing the performance and endurance of animals, as well as the parameters of mental performance of athletes in the main groups, in contrast to the data in the placebo control groups. Conclusions. An analysis of the prescription components of new types of ergogenic sports nutrition and the presented results of preclinical and clinical studies conducted on the basis of the evidence-based medicine paradigm regarding the effectiveness of specialized products indicate the complex action of these funds on various aspects of both physical and mental performance. From the materials presented in the article, it can be seen that specialized sports nutrition products of an ergogenic orientation can provide significant assistance in increasing sports results.

Inflammatory bowel disease is a multifactorial inflammatory condition. This study aimed to test the protective effects of Spirulina platensis against ulcerative colitis (UC). UC was induced in thirty-six male Wistar rats by adding dextran sulfate sodium (DSS) to their drinking water, while a control group received only drinking water. UC rats were equally-divided into six groups that received a single oral daily dose of vehicle (DSS), sulfasalazine (SSZ, 50 mg/kg/day), chloroform or the hydroalcoholic extracts of Spirulina platensis (100 or 200 mg/kg/day) for 15 days, and then blood and colon samples were harvested for determination of tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6), erythrocyte sedimentation rate (ESR), myeloperoxidase (MPO), and histopathology. At the end of the study, compared to time-matched controls, UC rats showed increased TNF-α (1.64-fold), IL-6 (5.73-fold), ESR (3.18-fold), and MPO (1.61-fold), along with loss of body weight (24.73%) and disease activity index (1.767 ± 0.216 vs. 0 ± 0), p < 0.001. These effects were prevented by SSZ treatment (p < 0.001 vs. DSS). The hydroalcoholic extract of Spirulina platensis dose-dependently modulated all DSS-induced inflammatory changes. However, the chloroform extract significantly lowered only IL-6 and ESR, but not TNF-α or MPO levels. The protective effects of the hydroalcoholic extract of Spirulina platensis against experimental UC involved mitigation of DSS-induced inflammation.

AbstractMonosodium glutamate (MSG) is one of the most widely spread food additives that might cause male infertility. However, Nigellasativa L. seeds (NSS) could provide a solution. This study was designed to investigate the potential effects of NSS on rats ingesting MSG. To achieve this aim, adult male albino rats were randomly equally assigned into three groups for 21 days: control group received no treatment, MSG group received MSG as 30 g/kg feed, and MSG + NSS group received MSG as 30 g/kg and NSS as 30 g/kg feed. Testis histomorphometry showed marked deterioration by MSG as atrophic seminiferous tubules with degeneration of their lining cells, damaged Leydig cells and decreased germ cells number. Periodic Acid Schiff stain indicated irregular interrupted basement membranes. Glutathione reductase, superoxide dismutase 2 (SOD2), and caspase-3 immuno-expressions increased in testicular cells. Testosterone levels were significantly decreased in MSG challenged rats along with significant increase in luteinizing hormone levels, whereas NSS normalized this hormonal profile. MSG exposure also caused significantly increased lipid peroxides (LPO), glutathione-S-transferase, and total antioxidant capacity (TAC) whereas nitric oxide and SOD2 were significantly decreased. NSS succeeded in rebalance LPO and TAC and ameliorated the histoarchitectural disturbances. NSS mitigated MSG-induced testicular impairment by its antioxidant and cytoprotective activities.

The paper studies the biological properties of film coatings created on the basis of polysaccharides (xanthan and carboxymethylcellulose) for use in various branches of the agro-industrial complex. It was found that samples of these film coatings completely decomposed in the soil in 7 days, and did in the aquatic environment in an average of 3.5 h. The effect of these film coatings on the organism of laboratory animals (rats) was studied by adding them to animal feed (experimental group). During the experiment, no deviations in behavior were noted in the experimental group of rats; no death in both the control and experimental groups of animals occurred. The studied film coating had no negative effect on the large intestine microbiocenosis and the animals’ weight. It was shown that the number of mesophilic aerobic and facultative anaerobic microorganisms in the experimental group was 3 times less than in the control one, and the number of lactic acid bacteria of the genus Lactobacillus was 3.3 times higher than in the control group. The results obtained indicate the biological safety of the use of the studied film coatings.
