Abstract The experiment was conducted on 18 Wistar rats during a six-week period; 12 animals were given zinc lactate (120 mg/rat and week) in feed mixture and 6 control animals were fed a standard mixture for rats (ST-1). Sixteen biochemical parameters were measured from blood (serum) samples: total protein (TP), albumin (ALB), urea (UREA), glucose (GLU), triacylglycerols (TAG), non-esterified fatty acids (NEFA), cholesterol (CHOL), creatinine (CREAT), alkaline phosphatase (ALP), aspartate aminotransferase (AST), uric acid (UA), magnesium (Mg), calcium (Ca), phosphorus (P), and trace elements such as Fe and Zn. When compared to the control group, we found that rats fed zinc lactate had higher concentrations of GLU, UA, UREA, Fe, Mg, Ca, TAG, TP, ALB, and ALP in the blood serum. Contrarily, the concentrations of AST, NEFA, CHOL, CREAT, P, and Zn were higher in the blood serum of control rats. Statistically significant differences between rats fed Zn and the control were found only in the concentrations of GLU, AST, ALP, UA, and P.

The aim of this study was to analyse the influence of linoleic acid which was added in the broiler chickens feed mixtures in relation to chemical composition of meat, content of fatty acids and composition of blood serum. There were compared the characteristics of two groups of ROSS 308 chickens in the experiment (the experimental group with 5% addition of linoleic acid and the control group). The protein content of breast was significantly lower (P ≤ 0.05) in the experimental group than in the control group. There were found significant differences (P ≤ 0.05) in the protein content between sexes. There was found statistically significant (P ≤ 0.01) higher fat content in the breast of experimental group in comparison with control group. Statistically significant differences (P ≤ 0.05) were found in fat from the thigh meat of experimental group than the control group. The analysis of the chemical composition showed higher content of fat in the breast (1.9 g.100 g−1) than in the thigh (11.66 g.100 g−1) of chickens which were fed with the addition of linoleic acid to feed mixture. This resulted in lower share of the other components. The addition of linoleic acid in the chickens feed mixture showed significantly higher proportion of polyunsaturated fatty acids to saturated fatty acids (0.76). Analysis of blood serum showed higher concentration of chlorides (P ≤ 0.01) in the group with the addition of linoleic acid than the control group. Proportion of monounsaturated fatty acids was 47.06% in the experimental group and significantly higher one (53.77%) was found in the control group.

Adipose tissue is an endocrine organ and has central role in interaction with other organs or tissues while propolis can induce lipolysis. Therefore, the aim of this study is to provide detailed information about adipose tissue homeostasis modifications and body composition during propolis supplement consumption. Twenty male Wistar albino rats (8 weeks) were divided into two groups of 10 animals each and fed for 90 days with two different types of diets: standard for the control group (diet C) and standard diet + 2% propolis (diet P). Thyroid hormones did not show differences, while ghrelin and adiponectin decreased in the group that was fed propolis. Insulin, leptin, and non-esterified fatty acids also increased along with reduced body weight and fat, in addition to increased lean mass when propolis was in the diet. We conclude that propolis could decrease ghrelin and adiponectin but increase non-esterified fatty acids and insulin secretion, which improves body composition.

The reproductive traits of sows are of paramount importance in the production of high-quality pork. The world experience of pig farming shows the need to solve first of all the feed problem. Diets unbalanced in the content of vitamins restrain the manifestation of genetically inherent high prolificacy of sows. The purpose of the research was to study the influence of feeding the vitamin feed additive “LipoCar” on the reproductive traits of sows and the biochemical parameters of blood serum. The results of research on the introduction of vitamin feed additive “LipoCar” into the diet of pregnant sows have been presented in the article. The experiment has been carried out in the production conditions in JSC “Linevsky pedigree farm” on sows of Large White breed. Pregnant sows have received a basic diet, balanced for all the normalized elements of nutrition. Sows of the experimental group in the composition of the basic diet fed the feed additive “LipoCar”. The dosage of the drug “Lipocar” was 2,1 g/head/day. “Lipocar” has been fed for 20 days. The total duration of the experiment was 3 months. When introducing the vitamin feed additive “LipoCar” into the main diet of sows in the second half of pregnancy the increase in the number of piglets in the litter by 1,6-6,8 % and the weight of the litter – by 5,6-56,2 % (P ≤ 0,001) have been revealed in comparison with the control group of animals. There was a higher content of carotene in the blood serum of sows of the experimental group by 50,0 % (P ≤ 0,01), vitamin A - by 48,7 % (P ≤ 0,05), and total protein – by 4,9 % (P ≤ 0,05).

Background. Herbal medication is a worldwide and ancient practice, mostly in developing countries, where a large part of the population is involved in this practice. Hence, studies must be conducted to evaluate their safety and efficiency to avoid or prevent toxicological risks due to their usage. In Togo, Carissa spinarum is a medicinal plant belonging to Apocynaceae family, used as an aphrodisiac or to heal some ailments including malaria, sickle cell anemia, hypertension, pain, and asthma. Notwithstanding its several ethnomedicinal benefits, just a few toxicological data associated with its chronic use are available. Objective. Therefore, this study aims to assess the toxicity of an ethanolic root extract of Carissa spinarum in Wistar rats. Methods. The 90-day oral toxicity process following OECD TG 408 guidelines is used. Male Wistar rats received Carissa spinarum root hydroethanolic extract at 500 and 1000 mg/kg for 90 days by oral gavage. Body weight changes, hematological and blood biochemical parameters, organ weight changes, malondialdehyde as a lipoperoxidation marker expressed according to tissue proteins, and histopathology of vital organs were assessed. Results. No signs of toxicity or mortality were observed during the 90 days experiment. Hematological parameters have not shown any treatment-related abnormalities. According to biochemical parameters, an increase in the chloride ion level was observed at 1000 mg/kg p < 0.01 . There was no significant difference between the treated groups and the control group concerning the malondialdehyde concentration, body weight, and organ relative weight. No changes in necropsy and histopathology of vital organs associated with extract treatment were observed. Conclusion. The results indicated that an ethanolic root extract of Carissa spinarum does not cause adverse effects, which can lead to Wistar rats’ death after 90-day oral administration at 500 and 1000 mg.

Introduction: Dyslipidemia is a prevalent condition in obesity and type 2 diabetes. Although fish oil rich in omega-3 fatty acids (ω-3) is a widely used hypolipidemic agent, it is often required at high doses. At high doses, these fatty acids can induce oxidative stress or endothelial activation and therefore, strategies to improve their beneficial effects are needed. We previously reported that fish oil in combination with cyclooxygenase (COX) inhibitors exerts enhanced hypolipidemic and anti-inflammatory effects in low density lipoprotein receptor knock-out mice. Here, we sought to determine the effects of ω-3 fatty acids in combination with naproxen (NX), a COX inhibitor, on dyslipidemia and gene expression in subcutaneous adipose tissue (scAT) in humans. Methods: Obese dyslipidemic patients were randomly assigned to receive one of these interventions (n=8/group) for 12 wk: 1) Standard nutrition counseling (control), 2) ω-3 (2 g twice daily), 3) NX (220 mg twice daily), and 4) ω-3 (2 g twice daily) + NX (220 mg twice daily). Results: The body mass index, HOMA-IR, and plasma total, LDL, and HDL cholesterol levels were not altered significantly in any of the groups. The percent change in plasma triglycerides (TG) from baseline was 75% ( P <0.1) and 68% ( P <0.05) in ω-3 and ω3 + NX-treated subjects, respectively. Notably, 25% of subjects who received ω-3s alone did not show a reduction in TG whereas all the patients that received ω-3 + NX showed a reduction in TG. Realtime PCR analysis of scAT showed that the expression of glucose transporter 4 (GLUT-4), a marker of glucose uptake and a key regulator of glucose homeostasis was significantly reduced in ω-3 compared to control group ( P <0.01). However, combining NX with ω-3 abolished this effect. Moreover, the expression of MCP-1 and VCAM-1, markers of inflammatory response or endothelial activation, was significantly increased in ω-3 but not in ω-3 + NX group. The plasma levels of MCP-1 and E-selectin did not vary significantly in any of the groups. Conclusions: Our data reveal previously unrecognized effects of fish oil in scAT. Our data suggest that combining NX with ω-3 fatty acids will increase their effectiveness in reducing plasma TG and improve the benefits of ω-3 supplements by favorably altering gene expression in scAT.

ABSTRACT Objective Iron deficiency and vitamin A deficiency are two of the main micronutrient deficiencies. Both micronutrients are essential for human life and children's development. This study aimed to investigate the effects of vitamin A deficiency on ferritin and transferrin receptors' expression and its relationship with iron deficiency. Methods Five diets with different vitamin A-to-iron ratios were given to thirty five 21-day-old male Wistar rats (separated in groups of seven animals each). The animals received the diet for six weeks before being euthanized. Serum iron and retinol levels were measured as biochemical parameters. Their duodenums, spleens, and livers were analyzed for the expression of ferritin and transferrin receptors by Western Blotting. Results Regarding biochemical parameters, the results show that when both vitamin A and iron are insufficient, the serum iron content (74.74µg/dL) is significantly lower than the control group (255.86µg/dL). The results also show that vitamin A deficiency does not influence the expression of the transferrin receptor, but only of the ferritin one. Conclusion Vitamin A deficiency regulates the expression of ferritin in young male Wistar rats.

The aim of the study was to evaluate the main and interactive effects of chromium(III) propionate complex (Cr3) supplementation and different iron supply on the carbohydrate metabolism, lipid profile and other selected biochemical parameters of rats. The experiment was carried out in a two-factor design, in which rats were fed a diet with different proportions of Fe(III) and Cr(III) for six weeks. Fifty-four healthy female Wistar rats were divided into nine experimental groups with different Fe(III) levels, i.e. adequate—control group (45 mg/kg)—100% recommended daily dietary dose of Fe for rodents, deficient (5 mg/kg) and oversupply (180 mg/kg—400%). At the same time they were supplemented with Cr(III) of doses 1 (adequate), 50 and 500 mg/kg of diet. The activity and concentrations of most biochemical parameters were measured with standard enzymatic, kinetic, and colorimetric methods. HOMA-IR and QUICKI indexes were calculated according to appropriate formulas. It was found that there was an interactive effect of high Cr(III) doses and different Fe(III) levels in the diet on the carbohydrate metabolism and insulin resistance indexes. The presented results suggested that iron deficient diet fed animals led to insulin resistance; however, an effect is attenuated by Cr(III) supplementation at high doses. There were no significant changes in the rats’ lipid profile (except for the high density lipoprotein cholesterol (HDL-C) level) and most of the other biochemical parameters, such as the leptin, aspartate aminotransferase (AST), alanine transaminase (ALT), total protein (TP), creatinine (Crea) and the urea (BUN) concentrations. The study proved that the Cr(III) supplementation, independently and in combination with diversified Fe(III) content in the diet, affected the carbohydrate metabolism and insulin resistance indexes but did not affect lipid profile and most of the other biochemical parameters in healthy rats. The findings proved the role of Fe and Cr(III) and their interactions on disturbances carbohydrates metabolism.

SUMMARY Changes in the plasma levels of non-esterified fatty acids (NEFA) in a group of patients with proven hypopituitarism have been compared with those found in control subjects during prolonged fasting, after the injection of insulin and after the oral administration of glucose with and without the previous administration of insulin. During a 4 hr. prolongation of an overnight fast plasma NEFA levels increased at a significantly slower rate in the patients with hypopituitarism. The intravenous injection of insulin was followed by a prompt fall in NEFA levels in the control group, and by a rapid return to or above original values. The recovery was consistently and markedly impaired in the patients with hypopituitarism and this abnormality differentiated them more clearly from the normal subjects than the abnormality in their plasma sugar response to insulin. The patients with pituitary hypofunction had a flat plasma sugar curve after the oral administration of glucose, but there were only minor differences from the normal plasma NEFA levels. Previous insulin administration impaired glucose tolerance in normal subjects and resulted in a more rapid late return of NEFA levels than after the administration of glucose alone. This late rise in NEFA did not occur in the hypopituitary group. The results obtained support the concept that pituitary integrity is required for normal fat mobilization. The consistency of the changes suggests that tests based on plasma NEFA measurements may provide a useful indirect means of diagnosing pituitary hypofunction.
