**Abstract.** We study an initial value problem for a semilinear
ordinary differential equation. This problem is closely related to the
blow-up behaviour of a semilinear parabolic problem.
Under some restrictions, we characterize the structure of solutions
and derive the uniqueness of positive global solution of this initial
value problem.

*Keywords:* initial value problem, semilinear, blow-up behavior,
global solution
