RESUMO
Umbilical endometriosis is a rare localisation of the disease. The authors report three cases of umbilical endometriosis. The symptomatology is not usually typic. The only effective treatment remains the surgical exercise thus allowing the confirmation histological.

The possibility of directly separating and measuring the impurity and lattice contributions to nuclear spin-lattice relaxation under the condition of a steady-state magnetic saturation is demonstrated in the particular case of 27Al nuclei in a gamma-irradiated ruby crystal. Contributions from trivalent and charge-exchanged chromium ions to impurity nuclear relaxation were separated. The number of charge-exchanged chromium ions was found. The spin relaxation time of Cr4+ centers was estimated.
