We take the X(1835) as a pseudoscalar baryonium state, and calculate the mass spectrum of the baryon-antibaryon bound states p (p) over bar, Sigma(Sigma) over bar, Xi(Xi) over bar and Lambda(Lambda) over bar in the framework of the Bethe-Salpeter equation with a phenomenological potential. The numerical results indicate the p (p) over bar, Sigma(Sigma) over bar and Xi(Xi) over bar bound states may exist, and the X (1835) can be tentatively identified as the p (p) over bar bound state.
