【Objective】To investigate the influence of serum containing Hechan Tablets(HT)on the proliferation and apoptosis of human lung adenocarcinoma cell(LAC)line.【Methods】Serum containing HT was prepared.Human LAC line was cultured by the routine method firstly,and then was planted respectively in the culture medium including serum containing HT at the concentration of 30%(group A),in the culture medium including blank serum at the same concentration(group B)and in RPMI-1640 culture medium(group C).The growth of LAC was monitored under inverted phase contrast microscope,histological features of apoptotic LAC nucleus examined under fluorescence microscope and the apoptosis of LAC observed by flow cytometry with the methods of DNA content analysis and terminal-deoxynucleotidyl transferase mediated nick end labeling(TUNEL).【Results】After treatment with serum containing HT,the apoptotic changes of LAC were as follows: apoptotic rate was 5.6% in group A,lower than 0.9% in group B and 0.1% in group C;DNA content analysis showed that the number of LAC which was in phase S and phase G2-M was less in group A than that in groups B and C 72 hours after the culturing,so did the cell proliferation index;the results of TUNEL examination showed that the incidence of cell apoptosis was 12.3% in group A,5.7% in group B and 1.2% in group C 72 hours after the culturing.【Conclusion】Serum containing HT has an inhibitory effect on the proliferation of LAC,and its mechanism may be related to inhibiting DNA synthesis and division of LAC,restraining LAC at the phase G0 and G1 and promoting LAC apoptosis.
