What does hyperplasia sex marrow resemble mean

Hyperplastic bone marrow is normally divided into five grades according to the degree of proliferation. The first grade is hyperplastic extremely active, mainly seen in acute and chronic leukemia, occasionally seen in some proliferative anemia. The second grade is hyperplastic obviously active, more seen in various proliferative anemia, such as iron deficiency anemia, megaloblastic anemia, hemolytic anemia, etc., or some leukemia. The third grade is hyperplastic activity, which is seen in the bone marrow image of normal people. Some anemia with poor compensatory hyperplasia can also be seen in partial hemodilution when bone marrow is obtained. The fourth grade is hypoplastic, which is more common in aplastic anemia and partial hemodilution of bone marrow. The fifth grade is extremely hypoplastic, which is seen in typical aplastic anemia.
