Results In the medium and high dose F0 groups, it was observed that the atrophy and incrassation of seminiferous tubule, decrease of spermatogenesis, hyperplasia of interstitial tissue, especially in high dose groups spermatozoon abnormality and nucleolus concentration in the rats testis after DU ingestion for 14 months. The changes became more severe with the prolongation of DU ingestion. Such changes occurred in filial rats (F1) after DC ingestion for 5 months. In the medium and high dose F0 groups, it was observed that a little atrophy of kidney glomerulus, hyperplasia of interstitial tissue after DC ingestion for 14 months, and kidney glomerulus fibrosis happened after DC ingestion for 20 months, such changes occurred in filial rats (F1) after DC ingestion for 5 months In the medium and high dose F0 groups, splenic germinal center and periarterial lymphatic sheaths were hyperplasia , companies with lymphopoiesis after DC ingestion for 7 months, splenic white pulp became more small and sparse after DC ingestion for 20 months.

结果 F0代的中、高剂量组大鼠摄入贫铀14个月后可见雄性的精曲小管萎缩，管壁增厚呈空虚网状，生精细胞层次减少，间质细胞增生，但仍见有精子生成；高剂量组可见到精子呈异型性改变，细胞核浓缩深染，且随着摄入时间延长改变愈趋明显；F1代大鼠摄入贫铀5个月后就有上述改变且更为严重。F0代中、高剂量组大鼠摄入贫铀14个月后肾小球轻度萎缩，间质增生明显，20个月时肾小球萎缩纤维化；F1代大鼠摄入贫铀5个月后就有上述改变。F0代中、高剂量组摄入贫铀7个月时脾脏生发中心和淋巴鞘增生，淋巴母细胞增生活跃，20个月时脾小体减少，生发中心稀疏；F1代大鼠摄入贫铀早期和晚期有类似改变。F0和F1代高剂量组摄入贫铀早期肝脏有炎症细胞浸润，晚期骨髓有核细胞减少，脂肪细胞增加。

He apoptosis of retinal ganglion cells could be observed one day after injury, increased by the 4th day, and reached a climax by the 7th day in the control group. Apoptosis of RGCs was detected with maniple at 4～10 days after injury in the experimental group and the rate of apoptosis in RGCs decreased significantly compared to the control group at 4～21 days.

UNEL染色及RGCs凋亡率：C组和D组在伤后第1天TUNEL染色可见凋亡细胞，第4天明显增多，至第7天达高峰。A组和C组在伤后第4～第10天仅可见少量的凋亡细胞，在第4～第21天，与B组、D组比较，RGCs凋亡率明显减少。

The typical apoptotic morphological features appeared in MUTZ1 cells treated with 4 mmol/L VPA for 72 hours. 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 dosedependent manner, ratio of cells at G0/G1 phase increased and ratio of cells at S phase decreased in dosedependent manner, the cells were arrested at G0/G1 phase.

结果显示： VPA对MUTZ1细胞的生长抑制作用呈现时间和剂量依赖性；经4 mmol/L VPA处理MUTZ1细胞72小时后，细胞呈现典型的凋亡形态特征，光学显微镜下可见凋亡细胞胞体固缩、核固缩、核碎裂及凋亡小体；透射电子显微镜下可见凋亡细胞核染色质边集、胞浆浓缩、密度增加，胞浆内大小不规则的染色质团块；流式细胞术结果表明，细胞凋亡率随着VPA浓度的增加而逐步增高，G0/G1期细胞比例随着VPA浓度的增加而逐渐增多，S期细胞比例逐渐减低，细胞被阻滞在G0/G1期。

Pathology and ultrastructure detection revealed cell necrosis and collapse, sever nuclear damage was observed in the death cells. The early characteristics of necrosis such as margination of heterochromatin was also found in some tumor cells. Besides, well differentiated tumor cells, degenerative tumor cells and some lymphocytes were seen.

直形针给药组肿瘤组织早期表现为大片的组织坏死，晚期表现为存活区域的增加，坏死区域与存活区域界限分明，两者间多有移行带；弧形针分段扇形注药者早期、晚期组织均表现为大片坏死，肿瘤间质内可见淋巴细胞浸润和纤维结缔组织增生；各时间段的检测标本中都可见一定数量的凋亡细胞，但比例远远小于坏死的肿瘤细胞。

By in situ hybridization, 53BP2 mRNA expression is revealed in tumor cell nests of NPC paraffin sections. The strong positive particles localize in the nuclei of tumor cells; but slight positive signals are also found in tissue cells of chronic nasopharyngitis and connective tissue, such as lymphocytes and smooth muscle cells; There are also positive signals in the nuclei of hyperplastic squamous epithelial cells. However, 53BP1 mRNA expression is not found in nuclei of tumor cells, tissues of chronic nasopharyngitis and connective tissue.

原位杂交结果显示，石蜡切片的鼻咽癌癌巢内，可见53BP2的强阳性表达信号，信号呈紫色颗粒状分布于胞核，核仁清晰可见；而在相同条件下，在慢性鼻咽炎组织和癌旁上皮的结缔组织，也可见弱表达信号，如淋巴细胞和平滑肌细胞；在增生的鳞状上皮细胞的核内，可找到强阳性信号。53BP1在鼻咽癌、慢性鼻咽炎组织和癌旁上皮的结缔组织切片上，均无表达信号。
