Test of NO, TNFa, LPS in the serum and ascites of the patients with liver cirrhosis ascites can contribute to distinguishing between exudative ascites and transudate ascites and distinguishing between spontaneity peritonitis is infected in Gram-positivebacteria and Gram-negative-bacteria so as to instruct clinical use of drugs.

肝硬化腹水患者血清及腹水中测定NO、TNFa、LPS，有助於鉴别渗出性腹水和漏出性腹水；有助於鉴别自发性腹膜炎是革兰阴性菌或革兰阳性菌感染引起，指导临床用药。

Animals in each group growth were good. No abnormal phenomenon was observed. ConclusionThe Trollius Beverrage's MTD of mice and rats was greater than 20000mg/. It was concluded that the product had no toxicity. The result of mutagenic test was negative and no abnormal phenomenon was observed after feeding for 30 days.

The expressions of peanut agglutinin, phasolus vulgaris agglutinin, ulex europaeus agglutinin and soybean agglutinin receptors during hepatocarcinogenesis induced by chemical carcinogen were studied with affinitive histochemistry.

结果部分卵圆细胞、过渡细胞之PNA，PHA，UEA阳性；正常肝细胞、增生灶、增生结节之PNA，PHA，UEA，SBA均阴性；肝癌组织中PNA，PHA，UEA，SBA均阳性。④结论在致癌剂作用下所出现的卵圆细胞及其分化的过渡细胞，与肝癌细胞具有某些共同的糖结合蛋白。

In this thesis, a meta statistical model is built to analysis microarray data of diverse stress on Saccharomyces cerevisiae from different labs to find stress unchangeably expressed genes with very low false positive rate and false negative rate.

本文采用meta统计模型寻找在不同环境条件刺激下表达保持相对恒定的酵母基因，使得到的基因的假阳性和假阴性都很低。

A represents the labeled fragments as position control; H1 represents the human H1gene as positive control; NEG represents the 431 bp fragment of bacterial 16s RNA as negative control; X,Y,Z,R,T,U represent the uncharacterized genes of SARS virus, which functions are unknown, the number under the parenthesis represents the position of each gene on the virus genome.

其中A表示利用已经标记好的片段作为坐标点；H1为人H1基因cDNA片段，作为芯片杂交的阳性点；NEG表示细菌16sRNA的一段长431bp片段作为芯片杂交的阴性点；X，Y，Z，R，T，U为推测的蛋白编码区，其功能还不清楚，括号内数字表示在基因组上的相对位置。
