  The paper is concerned with stabilization of a scalar delay differention
equation $$ {\dot x}(t) - \sum_{k=1}^m A_k(t)x[h_k(t)] = 0,~t\geq 0,~
x(\xi)=\varphi (\xi), \xi <0, $$ by introducing impulses in certain moments of
time $$ x(\tau_j) = B_j x(\tau_j -0), ~j=1,2, \dots ~. $$ Explicit stability
results are presented both for the equation with positive coefficients and for
the equation with $A_k$ being of arbitrary sign.
