After SBF solution cultivation for some days, the Ca/P coating was very easily deposited on the porous surface that was constituted of cystiform polygon made up with irregular nanometer circles like honeycomb. The energy spectrum showed that n/n atom ratio is about 1.61:1 which is very similar to that of HA and human bone. The active surface of the porous titanium after acid-alkali treatment and SBF solution condition which calcium-phosphorus ions was supersaturated induced the formation of Ca/P deposition layer.

The comprehensive evalucation resulted in a strong drought resistance group including ZXY04P-201、ZXY03P-227、ZXY03P-122 and ZX Y04P-136, a weak drought resistance group including ZXY04P-101、ZXY04P-89,ZXY04P-239 and a intermediate group including the others according to the the above indicators. 3. The results of study on drought mechanism for 4 Dactylis glomerata L. under continuously water stress and rewatering show: the water saturation deficit of leaves arose hastily, and ZXY04P-239 changed most obviously while ZXY04P-201 changed only slightly under drought stress. ZXY03P-173 and ZXY04P-201 increased in the relative plasmalemma permeability and the soluble sugar content while thant of ZXY04P-75 and ZXY04P-239 showed the trend of initial increasing, reaching the peak at the 8th day, then decreasing under drought stress.

20份鸭茅种质幼苗期抗旱性研究表明，干旱胁迫条件下，所有材料的株高、生物量显著下降，叶片脯氨酸和可溶性糖作为重要的渗透调节物质，其含量迅速增加，质膜相对透性的数值变大，细胞膜受伤害程度增大，水分饱和亏缺值变大，植物保水能力变弱，胞间CO2浓度增大；净光合速率、蒸腾速率、气孔导度和叶绿素含量等指标测定值减小，通过20份鸭茅种质苗期抗旱性综合评价，发现ZXY04P-201、ZXY03P-227、ZXY03P-122、ZXY04P-136属强抗旱性材料，ZXY04P-101、ZXY04P-89、ZXY04P-239属弱抗旱性材料，其他属于中等抗旱性材料。

The cardiomyocyte viability were detected by MTT assay for calculating the survival rate and the inhibitory rate of the virus. Myocardial F-actin and VEGF were analyzed by immunofluorescent staining with confocal microscopy. Mean fluorescent intensity of F-actin and VEGF were determined by flow cytometry.Results There is no toxicity on cardiomyocytes when PD is at concentration of 0.02 mmol/L and 0.2 mmol/L while there is toxicity at concentration of 2 mmol/L. CVB3 could reduce the viability of cardiomyocytes, depolymerize F-actin cytoskeleton and reorganize VEGF protein.
