  • Title: [ATP and ADP of platelets in chronic myeloproliferative disorders and multiple myeloma].
    Author: Terada H, Ohshima M.
    Journal: Rinsho Ketsueki; 1989 Jan; 30(1):22-8. PubMed ID: 2716195.
    Abstract:
    The content of platelet adenine nucleotide in chronic myeloproliferative disorders (CMPD) and multiple myeloma (MM) was measured by a luciferin-luciferase method by Holmsen and Weiss. The release of ATP and ADP from platelet during aggregation induced by collagen and epinephrine were analyzed. The total 42 investigated cases consisted of 11 cases of polycythemia vera (PV), 7 cases of essential thrombocythemia (ET), 7 cases of chronic myeloid leukemia (CML), 9 cases of blastic crisis of CML (BC-CML), and 8 cases of multiple myeloma (MM). The healthy control was 19 cases. In CMPD and MM, the amount of ATP was normal in spite of decrease of ADP; therefore, the ratio of ATP/ADP increased. On the other hand, the ATP significantly increased in BC-CML. MM revealed a remarkable increase of ATP release due to the aggregation by collagen and epinephrine. The maximal rate of aggregation of collagen and epinephrine using Lumi-aggregometer indicated a positive relationship with the ATP release by the Holmsen and Weiss' method. The platelet volume in CMPD increased showing correlation with ATP content and not with ADP. In conclusion, CMPD and MM are regarded as acquired qualitative disorders of platelets or secondary storage pool diseases from the view points of the abnormalities in ATP, ADP contents and their release. However, BC-CML and MM revealed some different change from that of CMPD.
