表明CB同样存在于经INV至PB的伤害性信息传导径路内，且传递内脏伤害性信息的CB神经元多于传递躯体伤害性信息的神经元，提示含CB的神经元可能也参与了经INV中继的外周伤害性信息向PB的传递。

The major results of this proposal are as follows:(1) ABA induces a rapid, substantial accumulation of apoplastic H2O2 in mesophyll and bundle sheath cells of maize leaves, and the accumulation of apoplastic H2O2 is involved in the induction of the chloroplastic and cytosolic antioxidant enzymes.(2) ABA-induced H2O2 production activates a 46 kDa MAPK, which in turn induces the expression of antioxidant genes and up-regulates the activities of antioxidant enzymes. The activation of MAPK also enhances H2O2 production, forming a positive amplification loop.(3) Water stress also induces the activation of a 46 kDa MAPK, which is dependent on the accumulation of ABA and H2O2 production induced by water stress and involved in the up-regulation of the expression and the activities of antioxidant enzymes.(4) ABA-induced H2O2 production mediates NO generation, which in turn activates a 46 kDa MAPK and results in the up-regulation in the expression and the activities of antioxidant enzymes in ABA signaling. NO-independent signaling is also involved in ABA- and H2O2-induced antioxidant defense.

本项目的主要研究结果如下：（1）ABA诱导的H2O2产生主要出现在叶肉细胞与维管束鞘细胞的质外体中，质外体H2O2的积累能够上调叶绿体与细胞溶质中抗氧化酶的活性；（2）ABA诱导的H2O2产生活化一个46kDa的MAPK，由此而导致编码抗氧化防护酶基因的表达与酶活性的上调；而MAPK的活化也能增强H2O2的产生，从而形成一个正的反馈调节环；（3）水分胁迫也能诱导一46kDa MAPK活化，这一MAPK活化依赖于水分胁迫诱导的ABA积累以及H2O2的产生，同时参与水分胁迫诱导的抗氧化防护基因的表达与抗氧化酶活性的上调；（4）ABA诱导一个依赖于H2O2的NO产生，NO活化一个46kDa的MAPK，从而导致抗氧化防护基因的表达以及抗氧化酶活性的上调；同时一个不依赖于NO的信号转导途径也存在于ABA诱导的抗氧化防护过程中。

Cribriform epithelial stomata were seen mostly in 1.5-month old rats.

筛状囊上皮孔主要存在于1.5月龄大鼠的松果体囊上皮，是由许多密集排列的囊上皮细胞周边部细胞膜凹陷形成的圆形孔洞，筛孔直径200—500nm；喇叭口状囊上皮孔见于1.5月龄和12月龄大鼠的松果体囊表面，由相邻上皮细胞向松果体内部凹陷，形成圆形或椭圆形开口，孔径1～4脚。

Further observations upon the nucleolus revealed that the density of the gold particles in the dense fibrillar component of the nucleolus was much higher than that of the fibrillar center,demonstrating that the protein was largely situated in the DFC rather than FC.

对核仁的进一步观察指出，在核仁中金颗粒主要分布在DFC，FC中的金颗粒很少，说明在核仁中SC35类蛋白主要存在于DFC组分中。

Finjan informed Google of the bug late last month and the problem was fixed within 30 hours, said Limor Elbaz, a vice president at Finjan, which is headquartered in San Jose, Calif.

据发现该缺陷的安全厂商Finjan公司称，这一跨站点脚本缺陷存在于Google的AdWords 广告计划和客户培训网站上。

Integrifolia lectins was slightly greater when mucus from infected fish was used, suggesting an increase of mannose and galactose binding lectins in fish skin exposed to parasites. As mannose, galactose and lactose are present on the glycocalyx of Gyrodactylus derjaini, it is suggested that lectins could play a dual role in interactions between fish hosts and their monogenean parasites.

integrifolia凝集素的抑制作用稍微更强，表明鱼类感染寄生虫后，皮肤中会与甘露糖和半乳糖结合的凝集素有所增加，由于甘露糖、半乳糖和乳糖存在于Gyrodactylus derjaini的外被多糖中，表明凝集素在鱼类寄主与单殖寄生虫相互作用中起双重作用。

The chimeric immunotoxin was expressed in E. coli with the yield of about 30% of the total bacterial protein.

型IL-4R由IL-4Rα链和IL-2Rγ链组成，主要存在于T，B淋巴细胞、单核细胞及血癌细胞表面。

The results showed that all of them could detect the presence of ZFY DNA sequences except a 46 XX"male"and a 46 XX hermaphrodite, our findings confirmed that Ferguson-Smith〔1966〕 forwarded the hypothesis that the X-Y intercharge model for XX maleness can be regarded as an abnormal exchange initaited in a region proximal to TDF and extending to the telomere,and,also strongly suggested that ZFY gene palyed an important role in sex determining of human.

结果除一例46XX两性畸形，一例46XX&男性&外，余均能检测到ZFY DNA序列(ZFY DNA序列存在于46XX真两性畸形和45XO Turner's综合症，在国内外尚未见报道)。证实了1966年，Ferguson-Smith提出的理论：在父源减数分裂期间，X-Y发生不等交换，导致Y染色体DNA插入性易位。XX男性是由于Y染色体上的TDF基因转移至X染色体上所致。
