    About 500 MASH(Macquarie/AAO/Strasbourg Hα planetary nebula, project) PNe were discovered towards the galactic bulge (Parker et al. 2006). For 405 MASH PNe with a diameter < 35 arcsec, we obtain surface brightness, diameter and dynamical age of the nebulae. From line intensity ratios of 133 GBPN observed with the 6dF device, we obtain their density and ionized mass, and their central star temperatures. We discover 15 bipolar and/or nitrogen-rich GBPNe having probably massive stellar progenitors (Peyaud, 2005).
