Vitamin E And C

The present study was undertaken to find out the efficacy of vitamin E and/or vitamin C against mercury (Hg) induced toxicity in mice. Sixty mice were randomly divided into 5 equal groups (n=12). One group of mice (Group A) was kept as control and each of rest four groups (B, C, D and E) were fed with mercuric chloride (HgCl2) in drinking water @ 65 mg/L. In addition to HgCl2 alpha-tocopherol (vitamin E) @ 100 mg/L, ascorbic acid (vitamin C) @ 250 mg/L and combination of vitamin E and vitamin C at same dose were given to the mice of groups C, D and E respectively. All treatments were continued for 28 consecutive days. Four mice of each group were sacrificed on day 1, 14 and 28 and efficacy of vitamin E and vitamin C against Hg induced toxicity were evaluated by observing toxic signs, body weight, hemato-biochemical parameters and postmortem lesions. Mild (++) toxic signs as evident by reduced feed and water intake, salivation, vomiting, excitement, muscle tremor, ataxia, restlessness, incordination and ruffled hair coat were observed from 2nd week (group B) and from 3rd week (group C and D) by intoxication with HgCl2. Significant (P<0.01) reduction of body weight (18.38%) and hematological parameters i.e. TEC (19.88%), TLC (27.89%), Hb content (34.09%) and PCV (9.15%) were observed at day 28 in HgCl2 induced intoxicated mice (group B). At identical period in same group biochemical parameters i.e. AST (46.99%) and ALT (58.72%) increased significantly (p<0.01). Pinpoint hemorrhages throughout the liver and highly (++++) congested kidney was also observed at post mortem (group B). All the parameters i.e. toxic signs, body weight, hemato-biochemical and post mortem lesions were found to be slight (+) or mild (++) and/or improved in rest three groups of mice following treatment with vitamin E, vitamin C and combination of vitamin E and vitamin C. The present study reveals that vitamin E and C have a protective role against Hg poisoning. However, combination of vitamin E and C gave better results.DOI: http://dx.doi.org/10.3329/pa.v19i2.16949 Progress. Agric. 19(2): 93 - 100, 2008

Background: Cadmium is a human carcinogen element and one of the most toxic pollutants in the environment. Present study aims at histomorphological study of some of the effects of Moringa oleifera oil and cashew (Anarcardium occidentale) nuts oil on Cadmium-induced liver damage in wistar rats. Methods: Thirty-five Wistar rats (80-180 g) were randomly selected and divided into seven groups of five rats each after acclimatization for two weeks. Group A which served as control received phosphate buffer, Group B received Cadmium only (3.5 mg/kg body weight). Group C received Vitamin C and Vitamin E; Group D received Vitamin C, Vitamin E and Cadmium. Group E received Cadmium and Moringa oleifera oil, Group F received Cadmium and Cashew nut oil and Group G received Cadmium (3.5 mg/kg body weight) and Moringa oleifera oil and Cashew (Anarcardium occidentale) nut oil. Results: Histological examination revealed normal histo-architecture of the liver, the central vein and the hepatocytes were seen clearly and there was orderly arrangement of the hepatocytes in Group A (control group). In group B, there was enlarged portal vein and there was distorted arrangement of the hepatocytes. In group C, the hepatocytes and the central vein were seen. In group D, the central vein and hepatocytes were seen though not orderly arranged. In groups E, F and G, there was restoration of the hepatocytes and the central vein was seen. Conclusion: This therefore suggests that Moringa oleifera oil and Cashew (Anarcardium occidentale) nut oil have ameliorative effects which led to the restoration of the damaged and distorted hepatocytes.

Background: Vitamin and mineral supplementation is common practice in both human and animal health, But indiscriminate, overdose and long term used may cause toxicity. The research work was designed to evaluate the effect of iron (Fe) &vitamin B12 (Vit-B12) on body weight, hematological parameters: Total Erythrocyte Count (TEC), Hemoglobin (Hb) and Total Leukocyte Count (TLC), and biochemical parameters: serum creatinine (SC), alanine aminotransferase (ALT) and aspartate aminotransferase (AST) levels in mice. Methods: One-month old 20 female Swiss Albino mice (Rattus norvegicus) having 19.52±0.54 g body weight were divided into four equal groups (n=5). After acclimatization, the mice of group A was treated with Fe@ 0.2 mg/kg body weight (bwt) in pellet, group B was treated with Vit-B12 @ 5 mg/kg bwt, group C was treated with combination of Fe and Vit-B12 and group D was fed with standard pellet and was considered as control. Results: The result showed significant (P<0.05) increase in body weight of treatment groups compared to the control group. The values of TEC, Hb and TLC in the treated groups were increased significantly (P<0.05). ALT, AST and SC values were decreased significantly (P<0.05) in the treated groups compared to the control group. Conclusions: It is concluded that administration of Fe and Vit-B12 significantly (P<0.05) increased body weight and hematological (TEC, Hb, and TLC) parameters however biochemical parameters (ALT and AST) were decreased significantly (P<0.05). In addition, combination of Fe&Vit-B12 showed better effects compared to their single uses.

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.

The vitamin E isoforms and vitamin (vit) C content of infant formulas were compared to human milk and related to relative susceptibilities to lipid peroxidation. We report that a highly distinct vitamin E and C profile exists between formula and human milk. Whileα-tocopherol (α-Toc) is the dominant vit E isoform in human milk, formula contains a substantial amount of α-Toc and δ-Toc that was greater than the level found in human milk (12- and 32-fold, respectively). Vitamin C was also two- fold higher in infant formula compared to human milk. Despite the higher vitamin E and C content, we also observed higher rates of lipid oxidation in the formula when compared to human milk. Storing human milk for one day at refrigeration temperatures did not produce hexanal in human milk, but this storage resulted in an increase in hexanal in formulas. We conclude that the higher concentrations of γ-Toc and δ-Toc in infant formulas did not provide similar protection from lipid oxidation as human milk. We also observed that vit C content was reduced during storage in both infant formula and human milk, which did not occur with the Toc isoforms.

Oral administration of sodium fluoride (40 mg/kg body weight) from day 6 to 19 of gestation caused, as compared to control, significant reductions in body weight, feed consumption, absolute uterine weight and number of implantations. Significantly higher incidence of skeletal (wavy ribs, 14th rib, <6 sternal centre, dumbell-shaped second and fifth sternebrae, incomplete ossification of skull and thickening of tibia) and visceral (subcutaneous haemorrhage) abnormalities were also observed in NaF-treated dams than that of control. Oral administration of vitamin C (50 mg/kg body weight) and vitamin E (2 mg/0.2 ml olive oil/animal/day) from day 6 to 19 of gestation along with NaF significantly ameliorates NaF-induced reductions in body weight, feed consumption, absolute uterine weight (only with vitamin E treatment) and number of implantations. As compared with NaF-treated alone, the total percentage of skeletal and visceral abnormalities were significantly lowered in fluoride plus vitamin C-treated animals. Vitamin E was less effective. These findings suggest that vitamin C significantly reduced the severity and incidence of fluoride-induced embryotoxicity in rats.

In rat myocardial damage was produced the administration of adrenaline in a dose of 2 mg/kg body weight (b.w.) subcutaneously for 2 consecutive mornings. This damage was assessed indirectly by significant increase in serum aspertate transminase (AST) and directly by microscopic changes in the myocardium.Pretreatment with the vitamin-C in a dose 10mg/kg body weight subcutaneously and preteatment with the combination of vitamin-C in a dose of 10mg/kg b.w. subcutaneously and vitamin-E in a dose of 50mg/kg b.w. orally for 10 days prevented the adrenaline induced myocadial damage equally which was evidenced by the equal prevention in the rise of serum AST & LDH levels as well as equal prevention of microscopic changes of the myocardium by the adrenaline.

Abstract Background; Dinotefuran is a new class of neonicotinoids claimed to be harmless to mammals and humans. This claim was daunted by the documented effect of dinotefuran on honeybees and further studies were required. Aim: The study was designed to assess the capaciousness of damage caused by prolonged exposure of dinotefuran in mammals and probable strategy to neutralize its effect. Methodology: Ninety-day trial using Wistar rats (n=45) was conducted while dividing them into three groups: untreated control group, insecticide (dinotefuran) treated group, and dinotefuran treated and vitamin E supplemented group. Dinotefuran was administrated orally (LD25). Vitamin E (alpha-tocopherol) supplementation was given in water ad libitum. Blood sampling was done twice a month, and hematological and biochemical data were recorded. After expiry of trial period, the experimental rats were anesthetized and sacrificed. Organs (kidneys, liver, and heart) were isolated from each groups, weighed, and stored at approximately -20°C till further processing, analysis and histopathology were performed. Results: All the hematological parameters were affected significantly. Histopathology of tissues showed clear necrosis in all the tissues except kidneys. All the biomarkers of oxidative stress and comet assay demonstrated significant cell damage. All the parameters showed improvement after vitamin E supplementation but non-significantly. Significance: These findings were suggestive that even low dose persistent exposure can lead to mutagenicity and carcinogenicity in mammals and other non-target species hence revised policy guidelines and more intelligent use of these chemicals is required.
