Sex- and organ-specific toxicity in normal and malnourished rats fed thermoxidized palm oil.
The effects of free radical toxicity as induced by chronic consumption of thermoxidized palm oil (TPO) diet on organ size of normal animals, their first filial offspring and malnourished rats, were studied. Tissue- and sex-specific toxicity was revealed. The TPO diet significantly (P<0.01) reduced lung and kidney mass in normal male rats but female rats remained unaffected. Hearts of first filial offspring of both male and female rats were, however, enlarged while lung, liver and kidneys of first filial female offspring were additionally reduced in size (P<0.01). This information suggests that the observed toxicities could be cumulative for female offspring. Malnutrition protected against toxic injury because none of the kwashiorkoric animals rehabilitated on the toxic diet showed any overt symptoms of toxicity.
