2确定了两种模式植物-拟南芥与盐芥的系统学位置和系统学关系，认为两者分别归于拟南芥属和盐芥属，其亲缘关系较远，拟南芥属靠近须弥芥属、荠属、亚麻荠属、旗杆芥属、无苞芥属、糖芥属以及垂果南芥等，而盐芥属靠近山嵛菜属和沟子荠属，对于它们的深入认识，为两种模式植物在进化领域研究物种抗逆适应与趋异分化提供了一个不可多得的比较模式系统，以及更多可供比较的物种，具有重要的应用价值。

In the long-period toxicity test, DCG was administered repeatedly for 60 days, the dose were 72.6,36.3,18.2 g/kg respectively(It refered to the dose of material,which amounted to 52.6,26.3,13.2 times of 50 kg human clinic use). There is no other abnormal changes about color patem,action,urine and stool,but cibation, hydroposia, body weight and index part of hematological and hematobiochemical parameters,coefficient and histomorphological figure of organs were examined during administration phase.The rats were examined in 21 days after the cessation of DCG, the abnormal changes of index was completely recovered.

Results 1. The expression of P53, KI-67, hTERT and ToPo II a protein was higher in astrocytoma than that in nomal brain tissue, the expression of these markers was obversely correlated to the grade of astrocytoma (P.05). The expression of Fas was higher in astrocytoma than that in nomal brain tissue, on the contrary, expression of P16 was lower in astrocytoma than that in nomal brain tissue.

结果 1、星形细胞瘤中P53、KI-67、hTERT与ToPoⅡα蛋白表达阳性率高于正常脑组织，P53、KI-67、hTERT与ToPoⅡα蛋白表达与星形细胞瘤的病理组织学分级呈显著正相关(P.05)；Fas蛋白在星形细胞瘤中的表达高于正常脑组织，而P16蛋白表达低于正常脑组织，Fas、P16蛋白表达与组织学分级无显著相关性。

The periostea of both experimental and control side of the mandibular ramus were taken and prepared, 2 of each 5 rabbits in a group were prepared for HE stain detection and 3 for proliferating cell nuclear antigen immunohistochemical detection.Results:1, The newly formed bone was detected on the lateral aspect of mandibular ramus after periosteal distraction. The bone was shaped like a hill. It looked very low and was full of holes at postoperative day 28. With the time of consolidation period lengthened, the newly formed bone matured gradually. X-ray examination showed the new bone shaped like a hill. The average values of new bone height at postoperative days 28,35,42 and 56 were 1.86 + 0.15mm, 2.29 + 0.29mm,3.19 + 0.13mm and 4.70 + 0.45mm. Histological examination of both HE stain and picricacid-fuchsin stain showed the increase in the number of osteoblasts and the change in the orientation of collagen fibers and bone trabecula. There were no significant differences between newly formed bone and original bone on the lateral aspect of mandibular ramus at postoperative day 56 histologically.2 Compared with the control side, the distracted periostea proliferated obviously under the microscope, and the number of periostealcells increased with satiation of cellular nuclear per unit area. The images of PCNA immunohistochemical stain of periosteum showed that the experimental periosteum proliferated obviously after distraction compared with the control side.
