[Neuroleukemia in suckling mice]

The whole skull and spinal column were histologically studied in 55 suckling mice (intact and with transplantable leukemia). It was stated that the lesion of the vertebral canal prevailed due to the extensive growth of leukemic infiltrates in the bodies of the vertebra which had incompletely formed cortical plate of the bone tissue. Such age-dependent unfinished formation of the bone marrow tissue may predispose a rapid development of neuroleukemia.
