The typical apoptotic morphological features appeared in MUTZ-1 cells treated with 4mmol/L VPA for 72hours. Pyknosis of cells and nuclei, disintegration of nuclear chromatin and apoptotic body could be observed by light microscopy. Aggregation and margination of nuclear chromatin, concentration of plasm, increment of density and chromatin mass of irregular size could be observed by transmission electronmicroscope. The flow cytometric analysis indicated that the VPA could induce cell apoptosis, apoptosis rate increased in dose-dependent manner, ratio of cells at G0/G1 phase increased and ratio of cells at S phase decreased in dose-dependent manner, the cells were arrested at G0/G1 phase.

The surface activity dose joins the queen, since jointly there is the water loving base group in the surface activity dose and detest the water base group in molecular structure , the pole is as a result easy to wind notable lessening menstruum surface tension from inside transition to interface in the solution.

液体分子在和空气等接触的表面会形成一层特殊的结构，表现为表面张力或表面能。表面活性剂加入后，由于表面活性剂分子结构中合有亲水基团和憎水基团，因而在溶液中极易从内部跃迁到界面上显著降低溶剂的表面张力。

RESULTS: The average dose of venlafaxine was (196±s 48) mgd^(-1), the average effective time was (8±3) d, and the effective rate was 68%. The average dose of mirtazapine was (32±11) mgd^(-1), the average effective time was (12±6) d, and the effective rate was 65%. The scores after treatment were significantly decreased in both groups. The scores of HAMA were (33±3)%(wk 1) and (50±3)%(wk 4) in venlafaxine group,(14±3)% and (31.0±2.3)% in mirtazapine group.

结果：文拉法辛组治疗剂量为(196±s 48) mgd^(-1)，显效时间(8±3) d，有效率68%，米氮平组分别为(32±11) mgd^(-1)、(12±6) d、65%。2组疗效量表评定结果均较治疗前有显著下降，特别是文拉法辛组wk 1和wk 4的HAMA减分率为(33±3)%和(50±3)%，米氮平组为(14±3)%和(31.0±2.3)%，前者下降更为明显。
