Results of analysis of RXTE observations of strongly absorbed X-ray sourcesIGR J16318-4848 and IGR J16358-4726 are presented. Careful subtraction ofGalactic ridge emission contribution to the observed spectra of RXTE/PCAallowed us to obtain the spectra of the sources in 3-25 keV energy band.Spectra of the sources cold be well described by a power law withphotoabsorption. It is shown that the value of absorption column in the case ofRXTE observation of IGR J16318-4848 performed on March 14.1, 2003 is somewhathigher that that obtained by XMM observatory on Feb 10.7 2003. This could implythat the source has variable absorption, presumably connected with an orbitalphase of the binary system. It is noted, that all three X-ray sources,discovered by INTEGRAL observatory in the sky region of (l,b)~(336,0) (IGRJ16318-4848, IGR J16320-4751 and IGR J16358-4726) have large intrinsicphotoabsorption and could be high mass X-ray binaries. This hypothesis hasindirect support from the fact that their are located close to the Norma spiralarm tangent, i.e. in the region of enhanced concentrations of young massivestars. If they are reside within this spiral arm some rough estimation of thesources distance could be made -- D~6-8 kpc.Comment: 4 pages, 4 figures. Submitted to Astronomy Letter
