To investigate whether the expression of cdc2 and cyclin B1 in spermatogenic cells during spermatogenesis is actually a temperature dependent event, in situ hybridization, Western blotting and immunohistochemistry analysis were used to study the expression of cdc2 and cyclin B1 in normal and cryptorchid testis. Results showed that heat would differentially hurt male germ cells in different developmental stages during spermatogenesis, especially the pachytene primary spermatocytes. Most of spermatogonia in contralateral cryptorchid testis were not harmed fatally by heat as yet, indicating that spermatogonia could resist to beat to a certain extent. In this case spermatogonia could develop to pachytene/diplotene primary spermatocytes, but they could not acquire the ability to complete the transition from mitosis to meiosis, and then appeared to go through apoptosis. Therefore, we could not find the descendants of meiosis: secondary spermatocytes and round spermatids, elongated spermatids and spermatozoon. The abdominal temperature had no significant influence on the transcription of cdc2 and cyclin B1 in the spermatogonia and pachytene/diplotene primary spermatocytes. In normal rabbit testis, cyclin B1 increased in the pachytene/diplotene primary spermatocytes before meiosis and reached its peak in the spermatids.

为了解精子正常发生过程中cdc2和cyclin B1表达的低温依赖性,我们利用原位杂交和免疫组化等方法,研究了正常和隐睾精子发生过程中cdc2和cyclin B1的转录和翻译调控活动,结果表明:(1)热对各阶段的雄性生殖细胞都有损害,粗线期的初级精母细胞尤为敏感,实验性隐睾内的精原细胞尚未完全受到"致命"影响,说明精原细胞对热有一定的耐受性,但即使成为粗线期/双线期初级精母细胞,却未能获得由有丝分裂过渡到减数分裂的能力,呈现不同程度的凋亡,所以在整个切片中找不到源自减数分裂的产物----次级精母细胞、圆形精子细胞,更谈不上长形精子细胞和精子的形成;(2)腹腔高温未明显地影响隐睾精原细胞和粗线期/双线期初级精母细胞中cyclinB1和cdc2的转录,说明高温并不是通过影响cyclin B1和cdc2的转录活动而导致生精过程阻断的;(3)正常兔睾丸组织中,〓在精原细胞和粗线期/双线期精母细胞中均有表达:cyclin B1蛋白在减数分裂前期的粗线期/双线期初级精母细胞中的表达量增加,于变态末期的精子细胞中达高峰。

Also the method of descent should be clearly stated where lower-offs are not provided.

同时,对下降方式的说明中须著明何处未设下降点。

The result shows the tribology properties are good, the kinetic friction coefficient are under 0.1. In the same conditions of wearing test, the weight loss of surface treated with EDC is about one tenth of the weight loss without treatment, and is about one sixth of the weight loss treated with electroless composite coating.

结果表明:在本试验的条件下,涂层的滑动摩擦系数较小,均在0.1以下,说明涂层的摩擦学性能较好;在相同的磨损实验条件下,用液中放电沉积方法处理过的表面磨损失重量是未处理表面的1/10左右,是化学复合镀方法处理表面的1/6左右,说明涂层的耐磨性相对较好。

Kirov et al. and Llevadot et al. successively found a new member of the HIRA family, DHIRA from D. melanogaster. Northern analysis showed that hybridization is strong in female adults, unfertilized eggs and 0-3-h-old embryos, then diminishes, but is still detectable.

Northern分析表明,在雌性成体、未受精卵和0-3时龄的胚胎中,dHira的转录本很高,之后急剧下降,说明它们在早期胚胎发育过程中可能起了重要的作用,但其具体功能还未见报道。

There were no significant difference between diabetics in hospital and diabetics who had participated diabetes education in gender,age,marital status,occupation, education level and the form of medical expenses.It is suggested that the two groups come from the same patients. 2.According to the result of content validity and retest reliability,questionnaire of compliance has a good validity and reliability.According to the result of consistence test,collection validity,discrimination validity and construct validity,SF-36 has a good validity and reliability.3.We used self paired comparison to analyze the data of the treatment compliance from the patients who had participated diabetes education and the patients in hospital who hadn\'t participated diabetic education.The results suggest that the treatment compliance of patients is improved as the number of times that these patients participated diabetes education was increased.The treatment compliance of the patients in hospital is improved just in a short-term period,who hadn\'t participated diabetes education.

研究结果1、住院糖尿病患者与参加健康教育的糖尿病患者在性别、年龄、婚姻、职业、文化程度、医疗用度承担形式上均无统计学差异,说明两组人群来自同一整体。2、根据内容效度和重测信度的结果证实允从性问卷具有良好的信度和效度;根据内部一致性检验、集合效度、区分效度和结构效度的结果证实SF-36量表具有良好的信度和效度。3、对参与健康教育的糖尿病患者进行的允从性跟踪调查结果进行自身配对前后比较,并与未参加健康教育的住院糖尿病患者的允从性得分进行比较,发现糖尿病患者治疗允从性随着参加健康教育次数的增多而进步;未参加教育的住院患者治疗允从性在进院和刚出院的短期内有一定进步,但随后逐渐下降至进院前水平。

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 effect of zeolites ion-exchanged by transition metals on thermal catalytic cracking reaction is studied. The product distributions of the cracking reactions catalyzed by theβor ZSM-5 zeolites exchanged with transition metals are different from that catalyzed by corresponding Hzeolites, which means the mechanism of cracking reactions has varied. Group Ⅷ metals Fe, Co, Ni and Cu, Zn are shown to be of strong catalytic activity of oxidative dehydrogenation, while Ti and Cr are not of oxidative activity. Catalyzed by zeolites or catalyst containing Ag, conversion of thermal catalytic cracking reactions and the yield of ethylene increase while the yield of propylene does not decrease. Silver can not only promote the formation of carbonium ion, but also convert carbonium ion into free-radical via redox reaction. The weak adsorption of olefins on silver reduces the occurrence of hydrogen transfer and dehydrogenation. As a result, the yield of light olefins is favored by silver in the catalyst.

采用过渡金属交换的分子筛作为催化剂,进行催化热裂解制取乙烯的反应,研究发现,在β沸石分子筛和ZSM-5分子筛中引入过渡金属后,催化热裂解反应的产物分布与相应的氢型分子筛相比有了较大的变化,说明过渡金属的加入对于催化热裂解反应的机理具有影响,Ⅷ族金属如Fe、Co、Ni和第Ⅰ、Ⅱ副族Cu、Zn表现出较强的氧化脱氢活性,产物中氢气、焦炭的产率很高,Ti、Cr则未表现出氧化作用:分子筛及催化剂中引入银后,催化热裂解反应的转化率和乙烯的产率有了提高,丙烯产率没有很大的变化,说明银在催化热裂解反应中能够促进正碳离子的生成,又有可能通过氧化-还原作用部分改变反应机理,促进了自由基的生成,并且由于银对烯烃的吸附很弱,其氢转移反应和脱氢、加氢活性比较低,有利于烯烃产率的提高。
