 +   <hidden TTP95-03  QCD Corrections to the rho Parameter > The three-loop QCD corrections to the $\rho$ parameter from top and 
 + bottom quark loops are calculated. 
 + The result differs from the one recently calculated  
 + by Avdeev et al. As function of the pole mass the numerical value is given by 
 + $\drho=\frac{3G_F M_t^2}{8\sqrt{2}\pi^2}(1- 2.8599\, \api  
 + - 14.594\, (\api)^2 )$.
