Results (1)ATP could inhibit the proliferation of U937 cells with inhibition rate over 43% after 48hour ATP treatment;(2)ATP treated U937 cells numbers increased obviously in G1 phase,and apoptosis peak appeared before G1 phase,apoptotic cell number was 3.4% for 24hour,and was 22.7% for 48hour of ATP treated U937 cells;(3) Nuclear chromatin condensed into sperical masses bound cytoplasma membrane formed apoptotic bodies which is shed from membrane surface into intercellular medium;(4) Apoptotic bodies were nigrosine staining negtive.

结果 (1)ATP对U937细胞的增殖有按摩明显的阻抑作用，加药48h后增殖的抑制率可达43%以上；(2)ATP处理的U937细胞周期发生改变，G1期细胞数按摩明显增多，ATP作用24h时G1期前出现亚二倍体峰——凋亡峰，凋亡细胞数为3.4%，作用48h时凋亡细胞数增多为22.7%；(3)ATP处理的U937细胞首先在核内染色质浓缩成半月形贴近核膜，逐渐向核膜外移动，进入胞浆内再移向质膜内外面，紧贴质膜外面再逐步脱离细胞体，进入细胞基质中，成为游离的凋亡小体。

The observation with histomorphology and phase contrast microscope: osteoclasts were large in size, multinucleus, foam-like cytoplasm with vacuole and pseudopodia, and movable. Acid Phosphatase reaction is positive.

经组织形态学、光镜和相差显微镜观察，破骨细胞具有胞体大，多核，胞浆泡沫状间有空泡，胞浆有伪足样突起，并可移动，酸性磷酸酶反应阳性。

I didn't watch TV last night, because it .

昨晚我没有看电视，因为电视机坏了。

Since this year, in a lot of villages of Beijing, TV of elevator liquid crystal was removed.

今年以来，在北京的很多小区里，电梯液晶电视被撤了下来。
