Effect of Vitamin E Treatments on The Humoral and Cellular Immune Responses in Mice: Animal experiment for nursing care of vitamin E-deficient patients

• Kim KJ

Abstract

Vitamin E, which has its advocates in the treatment of diabetes mellitus. autoimmune disease, cancer and peripheral vascular and thromboemboiic disease, has now been alleged to have a powerful antioxident effect and to affect various biological activities such as fertility factor, inhibition of human platelet aggregation and stabilization of biological membranes. The present study was designed to test whether vitamin E( alpha-tocopherol) can: (1)enhance the hemagglutinin response to sheep red blood cells (SRBC), (2)modulate Arthus and delayed type hypersensitivity(DTH) to SRBC and contact hypersensitivity to dinitrofluorobenzene (DNFB). (3)enhance the mitogenic response of murine splenocyte, (4)decrease the recovery of Cryptococcus neoformans from brain, lung, liver, spleen and kidney of infected mice and (5)have an inhibitory or enhancing effect on the induction of active systemic anaphylaxis(ASA) induced by chicken-gamma globulin (CGG) in mice. Mice were given either intramuscular injections of 0.3ml (300mg) of vitamin E before immunization or were infection for 10 consecutive days or were given by vitamin E esophageal intubation, 0.lml(l00mg), for 20 days before sacrifice for the mitogenic response experiments. It was found that vitamin E treated mice showed a significant enhancement in hemagglutinin response, Arthus reaction and DTH to SRBC and contact hypersensitivity to DNFB. There was no significant difference in the mitogenic response to phytohemagglutinin(PHA), but the response to concanavalin A(ConA) or pokeweed mitogem(PWM) was increased in vitamin E-treated mice. Interestingly, the vitamin E administration before C. neoformans infection decreased significantly the recovery of C. neoformans from brain, lung, liver, spleen and kidney of the infected mice as compared with that of the control mice, strongly suggesting that vitamin E pretreatment may increase the resistance of mice to the fungal infection. Unexpectedly, vitamin E administration enhanced the production of CGG-induced ASA. Taken together, it can be concluded that vitamin E administration may increase the humoral and cellular immune response and resistance to C. neoformans infection, but enhance the induction of ASA to CGG. Further studies are necessary to clarify the underlying mechanism accounting for these effects.
