The post-Newtonian parameters beta and gamma corresponding to 4-dimensional section of the metric are calculated. A family of solutions with gamma=1 is singled out. Some examples of solutions (e.g. in D=11 supergravity) are considered.12 pages Latex, submit. to Phys. Lett. BHigh Energy Physics - TheoryGeneral Relativity and Quantum Cosmologytext
