The X-ray spectra obtained with TENMA satellite are used to study the relation between active galactic nuclei and Galactic X-ray sources. Most X-ray pulsars produce strong iron emission lines with energy of 6.4 keV, while a few X-ray pulsars do not emit appreciable flux of iron lines. Low mass X-ray binaries, Sco X-1, Cyg X-2 and 4U1608-52 produce narrow 6.7 keV iron emission lines. Active galactic nuclei, NGC4151 and Cen A, produce strong 6.4 keV iron emission lines, while no appreciable iron emission lines are detected in the spectra of BL Lac objects PKS2155-304 and Mkn 421.
