Figure 2: Injection T3 with 0.5 mg/g per day to five groups of mouse and each group have 5 mice and killed after injection. Mix 5 livers and prepare mitochondria to test the state 4 respiration in different concentration of KCN. Result shows that the KCN sensitivity is decreased with increasing T3 injected. ○–○: one day injection; x–x: two days injection; ▲–▲: three days injection; ★─★: five days injection; ●–●: control ( no injection).
