In this paper,we reported mean platelet volume(MPV),platelet histogram and platelet distribution width(PDW)in 73 normal persons.We found that the MPV was 11.98±1.05 fl.The platelet histogram showed an abnormal distribution in normal persons.Its distribution range was between 5～23.75 fl,and concentrated Primarily between 6.25～15 fl,PDW was 36.85±2.51.At the same time,MPV,platelet histogram and PDW of 12 patients with cancer were determined before and after chemotherapeutiesd. Before chemotherapeutics,MPV was lower and PDW was higher than normal persons. After chemotherapeutics,both decreased and the platelet distribution moved toward the left,suggesting that MPV was a homogeneous decrease.These indexes show that determination of MPV,PDW and Platelet histogram are of value for studying the function of bone marrow and diagnosing some diseases of the thrombocytopenia and the thrombocytosis.
