[Intracellular cAMP concentration in isolated cells of white blood cell series of peripheral blood and bone marrow in healthy subjects and patients with different proliferative syndromes].
The level of cAMP was determined in isolated cells from bone marrow and peripheral blood of healthy subjects and patients with proliferative syndrome (acute and chronic myeloid leukaemia and chronic lymphatic leukaemia). In the investigations tritiated cAMP (3H-cAMP) was used and for binding of endogenous as well as exogenous cAMP protein isolated from bovine muscles was used. The mean cAMP level in peripheral blood granulocytes of healthy subjects was 27.90+/-3.82 pmol/10(7) cells and in normal lymphocytes it was from 11 to 18 pmol/10(7) cells. Much higher concentrations of cAMP: 56.4+/-16.25 and 52.7+/-11.02 pmol/10(7) cells were observed in myelocytes and metamyelocytes isolated from the bone marrow of healthy subjects. Lowering of cAMP concentration (below 4 pmol/10(7) cells) was observed in the lymphocytes of patients with chronic lymphatic leukaemia, while a higher cAMP concentration (above 90 pmol/10(7) cells) was found in the myeloblasts of patients with acute myeloid leukaemia.
