The rod apparatus for orthopedic treatment of pathology of the knee joint]

On the basis of study of remote results of application of wire apparatus, designed at KhNIIOT, for immobilization after correcting osteotomies in the area of knee joint due to varus-valgus deformation (114 cases, including 94 on crus, 14 on thigh, 6 on crus and thigh at the same time) there have been revealed essential advantages of this fixation method. It ensures possibility of additional postoperative correction, rated rigidity of fixation (depending on the stage of consolidation), strength of fixation, comfort for a patient and nursing. Consolidation has been achieved in all cases. Failure of rods in 6 cases (of 461 detected) and 5 cases of inflammation of soft tissues (skin bedsores-type).     

Age-related changes in the content of stromal clonogenic cells in hemopoietic and lymphoid organs

The content of stromal clonogenic cells in hemopoietic and lymphoid organs of mice and guinea pigs decreases with age. This drop is most pronounced in the thymus of mice and guinea pigs and in mouse spleen (more than 12-, 75-, and 8-fold, respectively). The contents of stromal clonogenic cells in the bone marrow of old mice and in the spleen of old guinea pigs are reduced by 50 and 40%, respectively, in comparison with young animals. These data indicate that the content of committed and inducible osteogenic precursors can decrease with age.
