good correlation has been found between erythrokinetic data ( simultaneous quantitative and qualitative disorders of erythroblastic proliferation in preleukaemic states ; pure qualitative disorders in primary sideroblastic anaemia ) and the results of culture of granulocyte precursors in the bone marrow ( small number of colonies , reduced size of colonies in preleukaemic states ; normal number and growth in non malignant refractory anaemia ) .
