In cotyledon, on one hand, very weak GUS staining was observed in PARF8:GUS, but very strong was found in phyA-209 PARF8:GUS. In the shoot apical meristem, hypocotyle and root tip, on the other hand, phyA-209 PARF8:GUS exhibited weaker GUS activity than PARF8:GUS.

Phenological data of 20 ligneous plants in Xi'an botanic garden from 1988 to 2002 was analyzed. The results showed that the spring phenological phenomena of all observed 20 ligneous plants had been earlier since 1988, while the autumn phenological phenomena of most observed 20 ligneous plants had been delayed. The response of the spring phenological phenomenon to the climate change was more obvious than that of autumn phenological phenomenon.

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。

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.
