Foetal muscles. Alkaline phosphatase (A), glutathione-S-transferase (B), catalase (C), glutathione (D), malondialdehyde (E) levels and the MDA/GST ratio (F) of the foetal muscle from Walker 256 carcinoma-bearing pregnant rats that were subjected to a leucine-rich or control diet. Legend: C – control rats; L – rats fed a leucine-rich diet; W – tumour-bearing rats; LW – tumour-bearing rats fed a leucine-rich diet; Cp – rats subjected to a similar, paired-nutrition intake of rats in group W; and Lp – rats subjected to leucine-rich diet and nutrition that was paired to the intake of rats in Group LW. * P < 0.05, significantly different compared to group C. • P < 0.05, significantly different compared to group L. aP < 0.05; significantly different compared to groups W and LW. # P < 0.05, significantly different from group W.
