A 2 × 2 factorial experiment (10 boars per treatment) was conducted for 16 weeks to evaluate the effects of the dietary n-6 : n-3 ratio (14 : 1 vs 6 : 1) and vitamin E (200 vs 400 mg kg–1) on boar sperm morphology and oxidative stress. Sperm mitochondrial membrane potential (MMP), reactive oxygen species (ROS), DNA damage (8-hydroxydeoxyguanosine; 8-OHdG), seminal lipoperoxidation (malondialdehyde; MDA) and antioxidant capacity in the serum, spermatozoa and seminal plasma were assessed as indicators of oxidative stress. Sperm production was similar among groups but increased (P < 0.05) throughout the 16 weeks of the study. Although sperm α-tocopherol content, ROS and seminal MDA did not differ between the two dietary n-6 : n-3 ratio treatments, enhanced antioxidant enzyme activity and MMP, but decreased 8-OHdG, were found in spermatozoa from boars consuming the 6 : 1 diet. The diet with the 6 : 1 ratio positively affected sperm morphology at Weeks 12 and 16 (P < 0.05). The α-tocopherol content and antioxidant capacity increased in boars with increasing levels of vitamin E supplementation. Compared with low-dose vitamin E, high-dose vitamin E supplementation improved sperm morphology. Overall, the results indicate that an n-6 : n-3 ratio of 6 : 1 and 400 mg/kg vitamin E have beneficial effects on sperm morphology by improving antioxidative stress.

Vitamin E Supplementation

Background: Oxidative stress and alterations in lipid metabolism observed in hemodialysis patients potentiate the low-density lipoprotein (LDL) oxidability, recognized as a key event during early atherogenesis. Objective: To explore the effects of an oral vitamin E supplementation on oxidative stress markers and LDL oxidability in hemodialysis patients. Methods: Fourteen hemodialysis patients and six healthy volunteers were given oral vitamin E (500 mg/day) for six months. Oxidative stress was assessed using: plasma and lipoprotein vitamin E levels [high-performance liquid chromatography (HPLC) procedure]; thiobarbituric acid reactive substances (TBARS, Yaggi method); and copper-induced LDL oxidation. All parameters were evaluated before initiation of vitamin E supplementation, and at three and six months thereafter. Results: At baseline, a significantly higher TBARS concentration and a higher LDL oxidability were observed in hemodialysis patients when compared to controls. After six months of vitamin E supplementation, TBARS and LDL oxidability were normalized in hemodialysis patients. Conclusion: Our data confirm that hemodialysis patients are exposed to oxidative stress and increased susceptibility to ex vivo LDL oxidation. Since oral vitamin E supplementation prevents oxidative stress and significantly increases LDL resistance to ex vivo oxidation, supplementation by natural antioxidants such as vitamin E may be beneficial in hemodialysis patients.

Vitamin E Supplementation

The purpose of the present study was to investigate the effect of vitamin E supplementation on autoimmune disease in New Zealand black×New Zealand white F1(NZB/W F1) female mice fed an oxidised oil diet. First, 5-month-old mice were fed an AIN-76 diet containing either 150 g fresh soyabean oil/kg (15S), 50 g fresh soyabean oil/kg + 100 g oxidised frying oil/kg (5S10F) or 5S10F supplemented with all-rac-α-tocopheryl acetate at 275 mg/kg diet level (5S10F5E) or 550 mg/kg (5S10F10E), respectively, in experiment 1. The results showed that mice fed the 5S10F10E diet had a lower anti-double-stranded DNA IgG antibody level and a longer lifespan than those fed the 15S and 5S10F diets. Therefore, the 5S10F and 5S10F10E treatments were repeated in experiment 2 for further analysis. The results showed that vitamin E supplementation in the oxidised oil significantly decreased thiobarbituric acid-reactive substance values in the kidney and spleen of NZB/W F1mice. Interferon-γ and IL-6 production by mitogen-stimulated splenocytes decreased in mice fed the 5S10F10E diet, whereas the secretion of IL-2 and IL-10 was not affected. The percentage of T-cells was significantly higher and that of MHC class II-bearing cells was lower in the spleens of the 5S10F10E group. The 5S10F10E group had a significantly higher linoleic acid (18: 2n-6) composition than the 5S10F diet group. Therefore, vitamin E supplementation in oxidised oil might decrease oxidative stress, anti-double-stranded DNA IgG antibody, regulate cytokines and lymphocyte subsets, and subsequently alleviate the severity of autoimmune disease such as systemic lupus erythematosus under oxidative stress.
