We present some results of observations of H2O masers (1.35 cm line) in Star-Forming Regions. The observations have been made from the beginning of the eighties at the 22 m radiotelescope at Pushchino, Russia (Lekht et al. 1995). The time interval between two consecutive observations is about one month. The spectral resolution is 0.1 km/sec and the sensitivity, for a time integration of 15 minutes, is about 10 Jy. The sources with which we deal in this work are: ONI, ON2, W31A, W75S, S128 and S252A. We pay attention to results of flux variations that are either common to all the sources or are results that allow to establish differences between them.
