From the nucleon structure functions measured by the CHARM Collaboration in inclusive neutrino and antineutrino CC interactions we determined the QCD parameters Λ MS = 310 ± 140 ( stat. ) ± 70( syst. ) MeV using the Furmanski- Petronzio method. With the same method we extrapolated the behaviour of the quark (q + q) and the gluon x -distributions up to Q 2 = 10 000 GeV 2 using perturbative QCD. The extrapolated structure functions are compared with recent results coming from the two-jet differential cross section in proton-antiproton interactions at √ s = 540 GeV and Q 2 = 2000 GeV 2 .
