Abstract:   
  In this note, we find a priori estimates in the $L_2$-norm for solutions
 to the Schrodinger equation with a parameter. 
 It is shown that a constant occuring in the inequality does not depend 
 on the value of the parameter.
 In particular, the estimate is valid for eigenfunctions associated
 with the Schrodinger operator with arbitrary boundary conditions.
