Figure 1: The total homocysteine level of rats’ plasma (36.29 ± 7.09 µmol/L) was obviously above the normal level (15 µmol/L) after they were fed with 2.5% methionine diet for 16 weeks. -Zearalanol treatment significantly lowered the total homocysteine level (19.20 ± 9.23 µmol/L). Data were expressed as mean ± SD; . Student -test; * versus HHcy. HHcy: hyperhomocysteinemia; tHcy: total homocysteine; -ZAL: -zearalanol.
