The four-week twice immunized hamsters acquired anti-MP in-fection capacity in local respiratory tract,as a result that swab culuturepositise was belove that of unimmunization group,and that only onehumster's lavage fluid culture was positive in immunization group.How-ever,unimmunization group positive rate of swabs and lavage fluid cul-ture was very high.This hinted that local respiratory tract's anti-MPinfection capacity was weak at the primary infection and the ability de-veloped gradually.4.The sIgA change in broncheal-lung lavage fluid.

而未免疫组咽拭子和支气管肺泡灌洗液MP分离培养的阳性均很高，说明在初次感染时，呼吸道局部防御清除MP的作用差，但随着时间的推移，其灌洗液培养的周次阳性率有下降趋势，MP培养的滴度亦随之降低，说明在感染以后随着时间的推移，呼吸道局部逐渐产生了防御、清除MP感染的作用。

The differences between the experimental and theoretical binodal curves might be caused by the error of the interaction parameters applied and by the neglect of the concentration dependency of g13 . Key word: Interaction parameters; Flory-Huggins; phase diagram

实验上观察到的液/液相分离现象与理论运算上所得到的结果趋势吻合，但实验点与理论所得到的binodal curve 有些误差，判断乃是由於作用力参数值估算误差，及未考虑g12 的浓度相关性所造成。

The results Showed that twenty isolates have the following biological aspects:① Capability of forming capsule,② Growth at 37℃ within 3days,③ Forming brown colonies on Niger seed agar, CACA agar,④ Urea hydrolysis test positive within 96 hours.⑤ No blue colonies were found on CGB agar.⑥ The genus could be identified by ID32 identification kid, but the species could not.⑦ The sequence of the LSUrDNA D1/D2 region analyzed confirmed to be C. neoformans var neoformans.⑧ Serotype A and AD were found in these isolates, Serotype A was predominant(83.33%),⑨ Some biodiversities of isolates existed.

结果 20株菌皆具有以下特征：①形成英膜，②37℃3天内生长试验皆为阳性，③咖啡酸玉米琼脂和油菊籽培养基皆可以产生褐色菌落，④尿素酶试验96h皆呈阳性，⑤CGB培养基未见蓝色菌落生长，⑥ID32鉴定板可以鉴定到属，种的鉴定结果各不相同，⑦大亚基核糖体DNA的D1/D2区域序列分析证实皆为新生隐球菌的新生变种，⑧血清型仅见A和AD二型，以A型为多数(83.33%)，⑨20株临床分离株随机扩增DNA多态性分析有一定的生态多样性。

These male sterile transgenic plants with TA29 Barnase gene have the same horticultural characters which can be also inherited steadily by plants in next generation as non transgenic ones. But their flowers bear fully catagenetic stamen lacking pollens, normal fragrant nectaries and strong pistils able to receive pollens from other plants or different cultivars and set seeds. At the meantime, the sterility i...

带有TA 2 9 Barnase基因的雄性不育植株的园艺学性状与未转化植株相同，并且其性状在后代中稳定不变；不育植株的花朵表现雄蕊完全退化，但蜜腺和雌蕊健全，能接受外来花粉，杂交结实率较高；同时，雄性不育植株的不育性在后代中出现分离，不育株率占 12 。5%～ 85.7%；此外，不育性状具有镶嵌性

Articular chondrocytes from the knee joints of the A group were separated respectively to fragments, and then digested by enzymes, both the chondrocytes and the uncomplite digested tiny chondral tissues have been cultured in vitro for about 2 weeks.

分别取A组9只兔子的双侧膝关节股骨滑车及部分髁部的软骨，在体外进行分离和消化，未完全消化的软骨组织加软骨细胞在培养瓶内一同培养2周后配制成浓度为1.6×10~8/ml的软骨细胞悬液，等分装于两个EP管中。

Observations on the dichotomous leaf venation of Circaeaster agrestis found no intermediate forms of the fusion of vascular bundles between the two completely fused commis-sural veins of anastomoses and the two separate approximate veins, but found different degrees of the vestige of commissural veins .

在星叶草叶二叉分枝脉序中，网结脉中2条完全汇合叶脉与靠近脉中完全分离叶脉间未发现任何形式的维管束汇合的中间类型，相反观察到了网结脉中不同程度的连接脉退化的痕迹，因此网结脉不可能由靠近脉形成；盲脉的出现与齿的退化、网结脉中连接脉的间断及非网结脉由分枝处间断等相关；上述事实表明星叶草叶的二叉分枝脉序应为一减化性状。

objective to analyze the drug resistance of staphylococcus aureusand provide suggestion for clinical rational use of antibiotics.methods secretion of those neonates suffered primary skin soft tissue infection and admitted during june,2005 to december,2007 was cultured and 113 strains of staphylococcus aureus were detected.we used k-b diffusion methods to determine their susceptibility to the common used antibiotics.results resistance rates of staphylococcus aureus to ampicillin/sulbactam,penicillin-g and cefazolin were 14.2%,40.7%and 6.2% respectively; there was no vancomycin-resistant strain.conclusion the resistance of staphylococcus aureus is not a serious problem in neonatal dermatic soft tissue infection.local treatment is the major approach in clinic,while general anti-infection consisting mainly of penicillin and first generation cephalosporin is chosen to avoid resistance mutation of staphylococcus aureus resulted from abuse of antibiotics.

多重聚合酶链反应快速鉴别葡萄球菌及。。。乳腺脓肿分离到葡萄球菌的鉴定和药敏。。。目的探讨金黄色葡萄球菌的耐药性，指导临床合理用药。方法对我院2005年6月至2007年12月新生儿原发性皮肤软组织感染患儿的分泌物进行培养，共检出金黄色葡萄球菌113株，并采用kb纸片扩散法对其进行常用抗生素的药敏试验。结果金黄色葡萄球菌对氨苄西林/舒巴坦、青霉素g及头孢唑啉的耐药率分别为14.2%、40.7%和6.2%，未发现耐万古霉素金黄色葡萄球菌。结论在新生儿皮肤软组织感染中金黄色葡萄球菌的耐药问题并不十分严重，临床处理应以局部为主，全身抗感染治疗宜以青霉素及i代头孢类抗生素为主，避免过度使用抗生素加速金葡菌的耐药突变。

In this paper, the improvement of synthetic method of 2-acetylaminotropone is introduced. 3-Acetyltropolone reacted with low concen-tration methylamine solution and solvent was directly evaporated in reduce pres-sure to give 2-acetyl-7 -methylaminotropone in good yield.
