There were high density images shaped as rope and slip in lungs of model control group rats and the pleura near the images were a little thickening. In MTX treated group, there were high density images shaped as slice along pulmonary veins. The veins of the blood vessels were obscure and the edges were unclear. In TPT treated group,there were multiple high density images shaped as tubercle and slice and the boundary were not clear. In XFC treated group, the lungs' outlines were clear and the veins were welldistributed. High density images shaped as spot were found in part lungs.

12H treatment group compared with 12h model group: the level of SOD, MDA of the Gardenoside group is no different with the model group; the level of the SOD of the Baical in group increase and the level of MDA is no different; the level of SOD of the Concha Margatitifera Usta is no different and the MDA of it decreased than the model; the level of SOD of the Cholic Acid group increased and the level of MDA decreased; the level of SOD of the Hefang Group increased and the level of MDA of it decreased than the model group.

考虑nNos可能只是参与缺血早期的神经毒性作用。到缺血24小时这一时程已经减低或耗竭。大鼠局灶性脑缺血12小时模型组缺血脑组织P53光密度值含量较正常组明显增高（p＜0.01）。珍珠母治疗脑缺血12小时组缺血脑组织P53光密度值较缺血12小时模型组明显降低。胆酸治疗脑缺血12小时组缺血脑组织P53光密度值较缺血12小时模型组明显降低（p＜0.05）。栀子苷治疗脑缺血12小时组缺血脑组织P53光密度值较缺血12小时模型组明显降低（p＜0.05）。

The morphology and characteristics of enhancement were studied, and compared with histopathologic and angiographic findings.

结果：74％的肝细胞癌在动脉期呈高密度，76％在门静脉期呈低密度。10例门静脉期等密度的病灶在动脉期均呈高密度。

Results High dense renal cyst is usually homogeneous hypoechogenicity on sonograms and homogeneous high/iso attenuation on CT images and color doppler is helpful in diagnosing.Atypical angiomyolipoma usually shows homogeneous high attenuation on unenhanced CT images,homogeneous enhancement on enhanced CT and homogeneous isoechogenicity on sonograms.The CT features of Xanthogranulomatous pyelonephritisinclude multiple,rounded,low density areas with enhancing rings arranged in a hydronephrotic pattern known as bear paw sign.Acute focal bacterial nephritisshows wedge lesion and stripe sign on delayed enhanced CT images.

对氧磷酶由355个氨基酸组成，它与高密度脂蛋白中的载脂蛋白结合，能保护低密度脂蛋白免受氧化修饰，降低体内氧化型低密度脂蛋白水平，并且能破坏氧化型低密度脂蛋白中的溶血磷脂，与脂代谢有密切关系。

Also the phase transition temperature from hexagonal ZnTiO_3 phase to cubic Zn_2TiO_4 was lowed by adding V_2O_5. It was noticed that V enriched in the boundary of the exaggerated grains, while not be detected in the inner of exaggerated grains or in the boundary of small grains. At sintering temperature 50℃, orthotitanate phase Zn_2TiO_4 in zinc titanate ceramics with ≤1.00wt% WO_3 additions became major phase, while zinc metatitanate ZnTiO_3 became major phase with ≤1.00wt% WO_3 additions.
