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.

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

Context: Indomethacin is the most commonly and widely used nonsteroidal antinflammatory analgesic and antipyretic drug. Though it is effective drug in various diseases, indomethacin causes inhibition of spermatogenesis by lowering the pH of seminal fluid leading to infertility. On the other hand, vitamin E enhances spermatogenesis by increasing pH of the seminal fluid. Therefore, the present study was designed to observe the protective role of vitamin E on indomethacin induced low pH of seminal fluid in testicular damage. Objective: To observe the effects of vitamin E on indomethacin induced low pH of seminal fluid in testicular damage in Long Evans rats. Study design: An experimental study. Place and period of study: The study was carried out in the Department of Anatomy, Sir Salimullah Medical College, Dhaka in the period of August, 2005 to June, 2006. Materials and methods: Eightyfour mature Long Evans male rats were divided into four groups (I, II, III and IV). The rats of group I, II and III were treated with indomethacin at different doses and duration. Group IV rats were treated with indomethacin plus vitamin E at different doses for 49 days. The pH of seminal fluid were measured biochemically. Results: There was significant reduction (P<0.001) of pH of seminal fluid when the rats were treated with indomethacin at low (2 mg/kg body weight/day) and high (10 mg/kg body weight/day) doses for 7, 14 and 42 days, respectively. On the other hand, rats treated with indomethacin plus vitamin E for 49 days showed increase in pH of seminal fluid compared to other groups (P<0.001). Conclusion: It can be concluded from the study that vitamin E has potential role in the prevention of the antispermatogenic effects of indomethacin by increasing the pH of seminal fluid.

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.

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.

Oil Emulsions

In this study, water-in-extra virgin olive oil emulsions were enriched with vitamins. Water-in oil emulsions are heterogeneous systems able to solubilize both hydrophilic and hydrophobic compounds. Thus, hydrophilic vitamin C and lipophilic vitamin E were loaded separately or together in emulsion. A suitable emulsion composition was selected after considering different surfactant (mono and diglycerides of fatty acids, E471; sorbitan monooleate, Span 80; polyoxyethylene sorbitan monooleate, Tween 80) and water concentrations. The most appropriate emulsion, for the high stability, resulted the one containing concentrations of Span 80 1% w/w and water 1% w/w. The antioxidant effect of vitamins in emulsions was studied considering the variation of the peroxide values during storage. The oxidation reaction was slowed down in emulsions containing vitamin C, but it was quickened by the loading of vitamin E for its high concentration. In emulsions containing vitamin E, indeed, the peroxide values were higher than in emulsions prepared in the absence of vitamins or in oil. The antioxidant activity generated by the co-loading of vitamin C and E was very effective to the point that in presence of high amounts of vitamins the peroxide values did not change in about 40 days of storage, due to the vitamin E regeneration by vitamin C.

The interplay of hyperlipidemia and oxidative stress in atherosclerosis has been fairly established by previous studies. There remains however, paucity of data in this environment on the direct effects of antioxidants on atherosclerosis. This study therefore aimed at determining the protective effects of EDTA, vitamin C and Vitamin E on atherosclerosis in diet induced heperlipidemic wister rats. Thirty Wister rats were investigated in this study. The rats were randomly divided into five groups (n=6). The control group was fed with growers mash and water only while group II-V were induced with hyperlipidemic diet for ten weeks. In addition to the hyperlipidemic diet; group III received 1 g/kg body weight of EDTA, group IV received 1 g/kg body weight of vitamin C, group V received 1 g/kg body weight of vitamin E, and group VI received EDTA, vitamin C and E. The group’s treatments were orally for two weeks. C-reactive protein, Total cholesterol (TC), Triglyceride (TG), HDL-cholesterol, LDL-cholesterol, Total calcium and Total antioxidant status were analyzed using standard methods after the treatments. The study showed significant effect in the use of EDTA, Vitamin C and Vitamin E in the treatment of atherosclerosis in rats which could be due to their antioxidant and anti-hyperlipidemic properties. Therefore the combinations EDTA, vitamin C and vitamin E appear greatly protective against atherosclerosis.

Chronic Arsenic Exposure

AbstractBackground:Chronic arsenic exposure via contaminated drinking water is a global environmental health problem associated with hematological, hepatic and many serious systemic disorders. This study on adult male rats evaluated the protective effects of vitamin E (VE) and vitamin C (VC) against arsenic-mediated hematological and hepatic toxicities.Methods:Arsenic was administered orally as arsenic trioxide (3 mg/kg body weight/day), as a single dose for 30 consecutive days or along with VC/ascorbic acid (200 mg/kg body weight/day dissolved in water) and VE/α-tocopherol (400 mg/kg body weight/day dissolved in olive oil) as supplements. Multiple hematological and hepatic parameters were assessed.Results:Arsenic exposure caused significant reduction of erythrocyte counts (p<0.05), leukocyte counts (p<0.01) and hemoglobin (Hb) levels (p<0.01). Arsenic exposure also led to marked echinocytic transformation of erythrocytes resulting in increased morphological index (p<0.001). Altered serum oxidative balance was observed with a higher oxidative stress index (p<0.001). The results also showed a significant increase of serum cholesterol (p<0.05), low-density lipoprotein (p<0.001) and triglycerides (p<0.01), and decreased high-density lipoprotein (p<0.01) along with total protein (p<0.01). A marked elevation of hepatic thiobarbituric acid reactive substance (p<0.05) along with decreased reduced glutathione (p<0.001) levels were also observed. Interestingly, co-administration of VC and VE significantly prevented all the arsenic-induced alterations (p<0.05) except Hb content and serum protein.Conclusions:The present investigation offers strong evidence regarding the protective efficacy of co-administration of VC and VE against hematotoxicity and hepatotoxicity in adult male rats caused by chronic arsenic exposure.
