  The two loop (NLO) diagrams with quark content contributing to the gluon
Regge trajectory are computed within the framework of Lipatov's effective
action for QCD, using the regularization procedure for longitudinal
divergencies recently proposed by two of us in
http://arXiv.org/abs/arXiv:1110.6741. Perfect agreement with previous results
in the literature is found, providing a robust check of the regularization
prescription and showing that the high energy effective action is a very useful
computational tool in the quasi-multi-Regge limit.
