Total number of bacteria, coliform group, fungus count, Bacillus pyocyaneus and tubercle bacillus were examined.

结果90个麦克风中，细菌总数超标率为95.56%，其中有54.44%样本超标100多倍，最高40000cfu/25cm2；大肠菌群、霉菌、金黄色葡萄球菌的阳性率分别为33.33%，94.44%，2.22%；绿脓杆菌及结核杆菌均为阴性。

Results The identification method for ursolic acid was established; The calibration curves of unarm showed a good linearity in the range of 0.0448-0.448 μg (r=0.9999, n=6), the average recovery was 99.7%(n=6), with RSD of 1.2%.

结果 夏枯草的薄层鉴别方法快速、灵敏，阴性无干扰；蒙花苷在0.044 8~0.448 μg范围内呈良好线性(r=0.999 9， n=5)，平均回收率为99.7%(n=6)，RSD为1.2%。

Methods Twenty-two adolescent SD female rats were selected. All rats were killed by dislocation of cervical vertebra, the eyeballs were in paraffin imbedding and made to a series of sections, using immunohistochemical method; ERα and ERβ distribution were investigated in uvea tissue of rats; and quantitied by Tanaka scores analytical method. The uteri of rats was used as positive control and PBS as negative control.

选择青春期SD雌性大鼠22只，采用颈椎脱臼处死大鼠，取眼球作常规石蜡包埋，连续切片， SP免疫组织化学方法显示ERα、ERβ在葡萄膜组织的表达；采用Tanaka记分法对ERα、ERβ进行定量分析，并设正常大鼠子宫作阳性对照；PBS代替一抗作阴性对照。

Except for verdigris pseudomonas,Gram-negative bacilli were less resistant to levofloxacin than to the other three ones.Klebsiellas,verdigris pseu-domonas and acinetobacters were30.76%～33.33%resistant to ciprofloxacin.

除铜绿假单胞菌外革兰阴性杆菌对左氧氟沙星的耐药率均低于其他3种药物，克雷伯菌、铜绿假单胞菌、不动杆菌对环丙沙星耐药率在30.76%～33.33%。

The show has drawn much scorn regarding its voyeuristic nature.

这一节目由于其窥阴性而招致了极大的蔑视。
