  We present results of $Re (A_0)$ and $Re (A_2)$ calculated using HYP
staggered fermions on the lattice of $16^3 \times 64$ at $\beta=6.0$. These
results are obtained using leading order chiral perturbation in quenched QCD.
Buras's original RG evolution matrix develops a removable singularity for
$N_f=3$. This subtlety is resolved by finding a finite solution to RG equation
and the results are presented.
