In the abstract, these sentences (page 1, line 5) should be: 'Additionally, hepatic betaine-homocysteine methyltransferase concentration as well as its mRNA abundance and lecithin level were found increased (P < 0. 05) by betaine supplementation in both basal diet-fed rats and high-fat diet-fed rats. Betaine administration in high-fat diet-fed rats exhibited a higher (P < 0.05) concentration of hepatic carnitine palmitoyltransferase 1 (CPT1) compared with high-fat diet-fed rats.'
