从担孢子的体外萌发,人工接种方法、萌发,侵染和扩展过程的扫描电镜及乳酚油组织透明法观察几个方面研究了相互亲和的基因型的玉蜀黍黑粉菌担孢子培养物。结果表明(1)担孢子体外环境水份的连续蒸发和丧失可能是担孢子萌发的决定性因素;(2)玉蜀黍黑粉菌的质配及双棱菌丝体的形成需要在寄主组织内的特珠环境下才能完成;(3)注射接种是用担孢子诱发玉米苗发病的最有效的方法,其技术关键是让悬浮液自苗基部注入沿未展开的叶束上升到顶部苗心溢出;(4)担孢子的萌发及侵入完成于接种后3～24h;(5)接种后4～6d 左右,寄主肿瘤出现前,受侵杂组织内已充满网状的双棱菌丝体。

This review is a current summary of the role that both zinc deficiency and zinc supplementation can play in the etiology and therapy of a wide range of gastrointestinal diseases. The recent literature describing zinc action on gastrointestinal epithelial tight junctions and epithelial barrier function is described. Zinc enhancement of gastrointestinal epithelial barrier function may figure prominently in its potential therapeutic action in several gastrointestinal diseases.

Purpose. Twenty-six HIV patients with biopsy diagnosed spongiotic dermatitis (SD) were studied to determine their demographic and clinical characteristics. The condition was also investigated to determine if it was linked to the immune reconstitution inflammatory syndrome (IRIS). methods. All patients whose skin biopsies were diagnosed by a pathologist as SD were identified. medical records were reviewed to extract demographic descriptors, viral loads and CD4+ counts at the time that SD occurred. In an attempt to determine if the condition could be linked to Immune Reconstitution Syndrome (IRIS), the time from nadir CD4+ count to the occurrence of SD was determined. Results. SD patients were found to be older than expected but were similar to other clinic patients with regard to race/ethnicity and gender. CD4+ counts, viral loads were not related to SD. SD did not seem to be related to IRIS because few cases occurred within the time frame associated with IRIS. SD frequently appeared on the limbs although the literature suggests a more frequent appearance on the trunk and buttocks. Discussion. HIV clinicians may expect to see SD on occasion and it may appear in unusual body sites and at any time during the course of the infection.

逆冲构造现代概念在造山带内的应用已经编制了许多精细的可复原剖面。逆冲断层通常是以阶梯状几何形态恢复在未变形的地层平板上。自从Rich(1934)的工作以来,一般都假设逆冲断层是以阶梯状形态扩展的,而且上盘构造是由于逆冲断片沿下盘断坡向上运动所致。然而,逆冲断层常常以平滑断层面切穿已经褶皱了的岩层。平滑冲断层可以根据下盘的几何形态和应变状态来确定。如果确定了是平滑冲断层,那么只作一个平衡剖面和一个复原剖面就很不够了,必须建立序列平衡剖面反演变形历史。因为将逆冲断层恢复到扩展之前的状态时,逆冲断面迹线仅只起一个标志线的作用,因而复原成阶梯状并没有力学意义。断坡在断层面上并不一定是一个实际的台阶,而经常只是一个逆冲断层所切穿的平滑弧状地带。逆冲断层带中的韧性变形可能使深部地层长度减小,这就排除了必须使构造中的岩层保持固定长度的必要。造山带内带中的韧性变形使得这些带中平衡剖面的编制成为极大的难题。

Guignardia citricarpa, the plant pathogenic fungus that causes citrus black spot, was recently introduced into the United States. The development of this disease in the presence of multiple applications of copper per year to manage citrus canker warrants an investigation into the effects of copper on growth of isolates of G. citricarpa from citrus in Florida. Guignardia citricarpa and G. mangiferae isolates, confirmed by internal transcribed spacer (ITS) sequencing of ribosomal DNA and DNA homology, were inoculated on non-amended media and media amended with 50 and 500 μg·ml-1 copper sulfate. Radial colony growth was assessed over a 26 to 59 day period. Copper reduced the growth of G. citricarpa isolates in media amended with 500 μg·ml-1 copper but had variable effects on radial growth in media amended with 50 μg·ml-1 copper. There was little effect of copper on the in vitro growth of G. mangiferae isolates. Field application of copper with and without an adjuvant for the control of citrus black spot was undertaken in a commercial grove in Florida in 2011. Spray applications were made on a 23.3 ± 4.7 day interval and fruit accessed between December 2011 and march 2012 for black spot symptoms. Copper failed to reduce the proportion of fruit exhibiting symptoms compared to that of the controls.
