Using Pell equations on A,we give a new proof of the well-known fact that ifthe ideal class number of a real quadratic function field K = k equals to 1,thenD must be P or QR, where P,Q,R∈A are monic and irreducible ,and Q,R have odddegrees.

卧床第30 d，对照组和下肢肌力训练组的最大运动时间较卧床前显著降低(P.05)，而自行车功量计训练组较卧床前无明显变化，且较对照组和下肢肌力训练组显著升高(P.05)。

Result 1-3-β-D glucosan was found exceeding the diagnostic criteria (10pg/ml) of the kit in 18 cases of fungal rhinosinusitis; and it was found no more than 10pg/ml in all 5 cases of purely nasal septum deviation patients. One of the 18 cases of fungal rhinosinusitis patients is chronic invasive fungal rhinosinusitis, and its level of 1-3-β-D glucosan reaches to 21.82 pg/ml. We compared the result of the study group to the control groups, and found that there is significant deviation beteen the two groups.

结果 经过实验检测20例真菌性鼻窦炎(19例为真菌球型，1例为慢性侵袭性真菌性鼻窦炎)及5例对照组患者血浆中1-3-β-D葡聚糖的含量，可以发现其中18例真菌性鼻窦炎患者血浆中1-3-β-D葡聚糖的含量大于试剂盒的诊断标准10pg/ml，其中一例慢性侵袭性真菌性鼻窦炎患者血浆中1-3-β-D葡聚糖的含量达到21.82pg/ml，2例真菌性鼻窦炎患者血浆中1-3-β-D葡聚糖的含量小于10pg/ml，而对照组患者血浆中1-3-β-D葡聚糖的含量均小于10pg/ml，病例组与对照组间采用卡方检验测得卡方值为16.071，(P＜0.05)两组间有差异，有统计学意义。

We also observed the morphological changes of the kidneys. Results: In the control group,the amount of NO and MDA increased while that of SOD decreased (P.01, P.01and P.01), and the renal function and the nephric tissue were impaired on the 21st day after bile duct ligation compared with the sham-operation group.
