Experimental induction of vitamin E and selenium deficiency using deficient diet was carried out on fourteen pregnant Awassi ewes and their newborn lambs to study the effect of the deficiency on erythrocytes osmotic fragility and phagocytosis. From the fourteen deficient ewes, seven were vaccinated with Rev I vaccine and seven ewes as control group, and their newborn lambs were used in the study. Results were showed increased in the concentration of saline solution in start and complete erythrocyte hemolysis in deficient lambs (0.52 ± 0.01 and 0.54 ± 0.01) and (0.42 ± 0.01 and 0.44 ± 0.00) respectively and in deficient ewes (0.53 ± 0.01 and 0.54 ± 0.01) and (0.43 ± 0.01 and 0.44 ± 0.00) respectively. Results showed a low phagocytic index in deficient lambs (9.40 ± 0.87 and 10.60 ± 1.16) and in deficient ewes (12.14 ± 0.85 and 12.42 ± 0.75) compared to phagocytic index in control lambs (43.85±0.91) and in control ewes (43.14 ±0.91).

Experimental induction of vitamin E and selenium deficiency by deficient diet was carried out on Awassi ewes and their newborn lambs. The clinical signs were characterized by sudden death in 4 lambs out of 14 lambs in deficient group and other lambs showed a variable signs included inability to suckle, arched back, weakness, dullness, emaciation and recumbency. Serum selenium and vitamin E levels of these lambs were 0.01 ppm and 0.34 mg/L respectively. The clinical signs in ewes included loss of body weight and loss of wool, Weakness, dullness and recumbency. Serum selenium and vitamin E levels of these ewes were 0.02 ppm and 0.61mg/L respectively. It was concluded that vitamin E and selenium are essential antioxidants and their deficiency exposes the sheep industry to many serious losses.

Abstract Objective: Neurotoxicity is an adverse effect caused by cisplatin due to inflammation and oxidative stress in the central nervous system. The present study aimed to assess the effects of vitamin E injection on the learning and memory of rats with cisplatin-induced cognitive impairment. Methods: Male rats were administered with cisplatin (2 mg/kg/7 day; intraperitoneally [i i.p.]) and/or vitamin E (200 mg/kg/7 day; i.p.) for 1 week, and the control group received saline solution. Spatial memory was evaluated using Morris water maze (MWM). In addition, the hippocampal concentrations of malondialdehyde (MDA), thiol, and superoxide dismutase (SOD) were measured using biochemical methods. Results: According to the findings, cisplatin significantly increased the escape latency, while decreasing the time spent and travelled pathway in the target quadrant on the final trial day compared to the control group. Furthermore, pre-treatment with vitamin E significantly reversed all the results in the spatial memory test. The biochemical data indicated that vitamin E could decrease MDA activity and increase thiol and SOD activity compared to the control group. Conclusion: According to the results, vitamin E could improve cisplatin-induced memory impairment possibly through affecting the hippocampal oxidative status.

The role of vitamin E and selenium as protective agents against oxidative stress was evaluated by measuring liver chemiluminescence in situ. Weanling rats fed a vitamin E- and selenium-deficient diet showed liver chemiluminescence that was increased 60 and 100% over control values at 16 and 18 days respectively after weaning. At day 21, the double deficiency led to hepatic necrosis, as observed by optical and electron microscopy, and increased serum levels of lactate dehydrogenase and alanine aminotransferase. Single deficiencies, in either vitamin E or selenium, did not produce liver necrosis but increased liver chemiluminescence. Vitamin E deficiency led to a 23 and 50% increase in liver emission at days 18 and 20 respectively; selenium deficiency produced a 64% increase at day 16. The activity of liver selenium-glutathione peroxidase diminished to 13% of the control value in the rats fed doubly deficient and selenium-deficient diets. Activities of superoxide dismutase, catalase and non-selenium-glutathione peroxidase were not modified by the different diets. These results suggest that oxy-radical generation may play a major role in hepatic necrosis in vitamin E- and selenium-deficiency.

ABSTRACT: The purpose of this research was to confirm the changes occurring in the foot system of the heifers challenged with lipopolysaccharides (LPS), at the clinical, serum and histological levels. We studied 16 clinically healthy heifers, 14 months of age, placed in a confinement system. All the animals were provided with an accelerometer collar to establish their activity. They were categorized into two groups: the LPS group (n=8), or those which were administered two intravenous applications of 2 mL containing 0.5 μg/kg of body weight of LPS, with a 24-hour interval and the Control group (n=8) which were given two infusions of 2 mL of saline solution in the same time interval. General clinical examination and blood collection were done at 0, 4 and 8 hours post the LPS challenges and analyses of the hemograms and paroxonese-1 were performed. The animals were then slaughtered on day 4 and the laminar tissue was collected for histological analysis. The LPS group revealed a lower total leukocyte count with heart rate and greater activity. None of the animals revealed any abnormal signs symptomatic of foot pathology after histological analysis. Hence, the challenge with LPS failed to induce any clinical and histological changes in the foot tissue compatible with laminitis.

The purpose of the research was to clarify the effect of chicken broilers feeding in the composition of mixed fodder with Vitamins E and C on the cellular link of non-specific resistance of the organism and, in particular, the parameters of pseudoiesinophils phagocytosis in blood. The research was carried out on chickens broiler – 308 grown in the farm “Fedyuk M” in the Zolochiv district of Lviv region. The keeping of the chickens was cellular with free access to feed and water. Experiments were conducted in 4 groups of broiler chickens of 100 chicks in each according to the scheme: the control group was fed with the standard feed (SC) according to the existing norms recommended for the cross ROSS-308; the first experimental group in addition to the SC received vitamin Е 1g/10 kg of mixed fodder; the second experimental group received vitamin C 2.5 g/10 kg of mixed fodder; the third experimental groups in addition to the ration received Vitamin C 2.5 g/10 kg and Vitamin E 1 g/10 of mixed fodder. For carrying out of immunological researches in chickens blood was taken in different age periods: 27-, 34- and 41-day-old age. In the whole blood, the phagocytic activity of pseudoiesinophils (FA), phagocytic index (FI) and phagocytic number (FF) were determined. For research, the daily culture of Escherichia coli (strain VKM-125) was used. The stimulatory effect of vitamins E and C in the composition of mixed fodder for chicken broiler broilers on the indices of pseudoiesinophils phagocytosis of blood was determined. As evidenced by a significantly higher phagocytic activity, phagocytic index and phagocytic count of pseudoiselinophils in blood of chickens in the experimental groups by comparison with the control group. At the same time there was a direct correlation between phagocytic activity and phagocytic index and index in blood of chickens broiler in experimental groups. At the same time, the ability of blood pseudoiesinophils to phagocytosis of microbial cells was higher in chicken broilers, which were fed with vitamin E and C.

Background Blood transfusion remains the main therapy for anemia in β thalassemia major patients. However, frequent transfusions can cause oxidative stress in response to iron overload. Vitamin E is considered to be the best lipid-soluble exogenous antioxidant in humans. It can protect phospholipid membrane from peroxidarion. Erythrocyte osmotic fragility is a useful test to assess for the improvement of red blood cells in thalassemia patients after vitamin E supplementation.Objective To investigate the effect of vitamin E for improving erythrocyte osmotic fragility in β thalassemia major and for decreasing the need for frequent transfusions.Methods T his was a double blind placebo controlled randomized clinical trial on children aged 2-14 years with thalassemia major who received frequent blood transfusions. Fifty subjects were divided into 2 groups: group I with vitamin E supplementation and group II with placebo, as a control group, for a period of 1 month. Pre- and post-treatment data on erythrocyte osmotic fragility and hemoglobin level were analyzed with non-paired T-test.Results Improved erythrocyte osmotic fragility was found: in group I, pre-treatment 31.59 (SD 6.342)% to post-treatment 38.08 (SD 7.165)%, compared to the control group pre-treatment 34.40 (SD 6.985)% to post-treatment 29.26 (SD 9.011)% (P=0.0001). Comparison of the mean delta Hb level in group  I was 0.94 (SD 0.605) gr% and that of group II was - 0.23 (SD 1.199) gr% (P=0.0001).Conclusion Vitamin E supplementation improves erythrocyte fragility and Hb level in β thalassemia major pediatric patients.

PURPOSE: The objective of the experimental study is to detect the macroscopic and microscopic alterations of the mesenterium and parietal peritoneum when hypertonic glucose aqueous solution 10%-25% is administrated into the peritoneal cavity of the rat. METHODS: 90 Wistar females young rats adults were used weighin between 180-250 g, numbered 1 to 90, establishing unique group and divided in three groups (A, B, C) of 30 animals chosen aleatory manner. 0,9% saline solution was used called control group, or group A, 10% glucose solution named group B, and in the others 30 was used 25% glucose solution named group C, differing in the observation period, (06h, 24h and 48h), but with the same procedure. A midline abdominal wall laparotomy was made and in the animals of the control group was injected 2 ml of a 0,9% saline solution into the peritoneal cavity. After, we made a suture in mass without to include the peritoneum. For the others groups (B, C) the rats received 10% glucose solution and 25% glucose solution injected into the peritoneal cavity respectively. All groups were kept under observation and the results were submitted to statistical analysis by a longitudinal and transversal comparative study. RESULTS: A new surgery was done in 6h, 24h and 48h, and we observed in macroscopic evaluation, the presence of fluid, serous uniforme and rosy all over the cavity. Vascular congestion was present. We dried out 90 fragments of mesenterium and 90 fragments of parietal peritonium bilateral. In the microscopic study, necrosis was not present. For the mesenterium histological study we observed 16 cases (17,8%) unspecific chronic inflammation, 30 cases (33,4%) hiperplasic linfonod, 10 cases (11,1%) high vascular congestion, 6 cases (6,6%) reaction fibrosis and 28 cases (31,1%) no alteration. For the parietal peritonium histological study we observed 6 cases (3,3%) reaction fibrosis and 174 cases (96,7%) no alteration. Giant cell was not present. In the statistical analisys statistic there is no significance between the groups (p>0,05). CONCLUSION: Hypertonic glucose solution and NaCl 0,9% on the mesenterium and parietal peritonium do not produce tissue necrosis in a rat and the inflammation process has the same intensity.

Abstract Background: We conducted this study to discover changes of serum FGF23 in non-uremic rat model of vitamin D deficiency without secondary hyperparathyroidism using paricalcitol. Methods: 30 adult male rats weighting 300±20 grams were enrolled. They were divided into three groups of 10 rats including Control, Vitamin D deficient(VDD), and Vitamin D deficient diet treated with paricalcitol(VDD+P). Serum biochemical were checked twice, at baseline and after the 22nd day of study. Results: There was no significant difference in baseline laboratory data between groups. At the end of the study, 1,25(OH)D3 was reduced in VDD (P = 0.019) and VDD+P (P < 0.001) with a more significant decline in VDD+P group. Serum level of FGF23 was reduced in VDD+P group compared to the control group (P = 0.011) and VDD group (P = 0.021). serum PTH in VDD group was higher than the control and VDD+P group (P = 0.036 and P = 0.038, respectively). Conclusion: The present study showed that paricalcitol could reduce FGF23 in vitamin D deficient rats without any changes in serum calcium, phosphorous and fractional excretion of phosphorous, which might be due to low PTH and 1,25(OH)2 D3.

The purpose of this study was to clarify the effects of dietary calcium (Ca) supplementation on bone metabolism of magnesium (Mg)-deficient rats. Male Wistar rats were randomized by weight into three groups, and fed a control diet (control group), a Mg-deficient diet (Mg- group) or a Mg-deficient diet having twice the control Ca concentrations (Mg-2Ca group) for 14 days. Trabecular bone volume was significantly lower in the Mg - and Mg-2Ca groups than in the control group. Trabecular number was also significantly lower in the Mg - and Mg-2Ca groups than in the control group. Mineralizing bone surface, mineral apposition rate (MAR), and surface referent bone formation rate (BFR/BS) were significantly lower in the Mg - and Mg-2Ca groups than in the control group. Furthermore, MAR and BFR/BS were significantly lower in the Mg-2Ca group than in the Mg - group. These results suggest that dietary Ca supplementation suppresses bone formation in Mg-deficient rats.

Many mothers who give birth to Sectio Caesarea (SC) do not Initiate Early Breastfeeding (IMD), which fails exclusive breastfeeding. This study aimed to determine the effect of IMD management in postpartum SC mothers on nutritional status, speed of milk production, and quality of breast milk protein. Method: quantitative research with quasi approach experiment. The research design used was a pre-post-test control non-equivalent control group. A sampling of this study used the Consecutive method sampling with a sample of 20 mothers who gave birth by cesarean section (SC). Hypothesis testing uses the independent t-test and the Mann-Whitney test. The study results showed an influence on the management of IMD in postpartum SC mothers on the speed of ASI production (p-value=0.004) and nutritional status (p-value=0.028). There was no effect of IMD management on postpartum SC mothers on the quality of breast milk protein (p-value = 0.543). This study recommends that the hospital implement an IMD promotion program before the abdominal wall is closed as a form of intervention to increase milk production and maternal nutritional status
