Some corollaries of the Hasse principle for Brauer
group of a pseudoglobal field are obtained. In particular we prove
Hasse-Minkowski theorem on quadratic forms over pseudoglobal
field and the Hasse principle for quadratic forms of rank 2 or 3
over the field of fractions of an excellent two-dimensional henselian
local domain with pseudofinite residue field. It is considered also
the Galois group of maximal p-extensions of a pseudoglobal field.
