Abstract:
In earlier work we have reported that garlic and cabbage
extracts can protect laboratory animals from the toxic effects
of different mycotoxins. Previous research demonstrated that
fumonisin (FB) induced developmental effects in mice, rats and
hamsters. The objectives of the present study were to utilize
the pregnant rat as an in vivo model to compare the potential of
garlic and cabbage seed extracts to prevent the developmental
toxicity of FB and the effects of these extracts on sphingolipid
metabolism in dam and foetus livers. Six treatment groups
included a control group, a group fed on an FB-containing diet
(150 mg kg-1 feed) and groups treated orally with garlic or
cabbage extracts (5 mg kg-1 body wt.) with or without FB during
gestation days 6-15. Evaluations of toxicity were performed on
day 20. These include: maternal (mortality, body weight, feed
intake and litter weight), developmental (embryonic resorption,
foetal body weight, foetal soft-tissue anomalies and foetal
skeletal examinations) and maternal and foetal sphingolipid
metabolism. Fumonisin alone resulted in significant decreases in
feed intake, body weight gain, litter weight, number of live
foetuses and foetal body weight, whereas it increased
significantly the number of resorbed foetuses and the number of
skeletal malformations (30.4% for skull and 26.08% for
sternebrae) and also increased the sphinganine/sphingosine
(Sa/So) ratio in dam but not fetus livers. Garlic alone or plus
FB was comparable to the control regarding all the tested
parameters. On the other hand, cabbage seed extract alone or
plus FB resulted in 10% maternal mortality and a decrease in
maternal body weight and litter weight. It resulted in 4.65%
skull malformations in foetuses but it was comparable to the
control with regard to the other tested parameters. It could be
concluded that both garlic and cabbage seed extracts have
protective effects in pregnant rats. Moreover, garlic extract
was found to have a greater protective effect than cabbage seed
extract. |
