Abstract:
Objective:To observe oncosis in human peripheral blood T lymphocytes.Methods:Peripheral blood T lymphocytes of healthy adult was separated with Percoll(1.073 g/ml)and harvested by using nylon column.The cultured cells were divided into control and dexamethasone(DXM)group,and cell morphology was observed through light microscope,electron microscope and fluorescent microscope.And incidence rate of oncosis was analyzed by flow cytometry.Results:①Oncosis could be observed in cultured T lymphocyte after 96h.②In different concentrations of DXM group(1?10-6,1?10-5,1?10-4,1?10-3mol/L),The incidence of oncosis T lymphocytes was(3.49?0.42)%,(5.17?0.48)%,(8.44?0.72)%,(17.93?1.50)%.③During different cultured period(48,72,96,120h),The oncositic rate of T lymphocytes in DXM group was(0.53?0.10)%,(6.36?0.80)%,(20.60?1.59)%,(25.56?1.76)%.Conclusion:Oncosis can be seen in human peripheral blood T lymphocytes,and DXM could induce oncosis.
