BW: body weight, HW: heart weight. Basal; = 8, thyroxin (T4); = 9, propylthiouracil (PTU) + T4; = 11, recovery; = 10. significant change compared to basal, significant change compared to T4, and significant change compared to PTU + T4 (one-way ANOVA followed by Tukey-Kramer multiple comparison test).
