Mv. Morandi et al., Dietary vitamin E supplementation does not inhibit Candida albicans intestinal translocation in rats, J NUTR SC V, 45(2), 1999, pp. 153-161
Candida albicans translocation was determined in rats receiving a normal or
vitamin E-supplemented and deficient diet submitted to mesenteric ischemia
and reperfusion (MIR). The antioxidant effect of vitamin E on lipid peroxi
dation was also assessed. The animals were divided into six groups submitte
d to different diets for 30 d. Groups N, NI, NC and NIC were submitted to a
normal diet and used as controls, and groups VITE and DEFE received a vita
min E-supplemented and vitamin E-deficient diet, respectively, Groups NIC,
VITE and DEFE were submitted to MIR, inoculated with Candida albicans and s
acrificed 24 h after the surgical procedure. The antioxidant effect of vita
min E was determined in the liver and gut mucosa using the TBARS method. Ca
ndida albicans translocation was assessed in lymph node, liver and kidney s
pecimens. The results showed that lipid peroxidation was lower (p < 0.05) i
n the vitamin E-supplemented group. However, vitamin E supplementation did
not protect the rats against Candida albicans translocation (the translocat
ion in the Group VITE was 100% for lymph nodes).
