| 1 | 从菠萝薄细胞层切片直接诱导体细胞胚显示文摘以菠萝(Ananas comosus L. Merrill)杂交种MD1无菌苗为材料,通过培养薄细胞层切片(Thin cell layer,TCL)的方法,研究直接再生胚的固体培养体系。结果证明,预培养的设计2(在预培养基PT上黑暗预培养无菌苗1周后,从预培养苗茎顶端切取TCL,在MS+2,4-D2mg·L-1或1mg·L-1胚诱导培养基EI2上黑暗培养1周,然后转到光照条件下继续诱导胚1周,再在成熟胚培养基EM上培养2周,最后转入幼苗培养基PL上培养)是直接诱导获得体胚的最佳途径;诱导的体胚最初均来自于薄细胞层上微管束附近的细胞;picloram有利于芽的诱导,2,4-D有利于直接再生胚,但如果球形胚形成后一直培养在较高浓度的2,4-D培养基中,将阻碍球形胚和心形胚进一步发育为成熟胚,反而促进芽的生成。 | 梁雪莲 陈晓玲 Kheng Cheah Diane M Sether Qi Li John Hu | 2009 | 园艺学报2009，36，11： | 3 |
| 2 | 香蕉胚性细胞悬浮培养方法的改进显示文摘针对香蕉胚性悬浮细胞培养过程中存在的胚性愈伤组织的诱导率低、周期过长、胚性易丢失等问题,以'苹果蕉'及'威廉斯'香蕉的未成熟雄花为试验材料,对香蕉胚性愈伤组织的诱导、悬浮培养的理化条件进行改进。结果表明:(1)光照条件较暗培养更有利于诱导理想的香蕉胚性愈伤组织;(2)M1培养基中加入酪蛋白和脯氨酸有利于胚性愈伤组织的诱导;(3)用微孔板代替三角瓶悬浮培养,有利于悬浮细胞分裂增殖,而且可减少污染的可能。 | 李敬阳 唐粉玲 John S.Hu Wayne Borth Kheng Cheah 谷会 金志强 | 2012 | 热带作物学报2012，33，5： | 2 |

| 4 | Melioidosis:a rare cause of anterior chest wall abscess显示文摘Melioidosis is an unusual tropical infectious disease caused by the gram-negative bacterium Burkholderia pseudomallei,which was formerly known as Pseudomonas pseudomallei. Melioidosis is characterized by abscess formation and it may manifest in any part of the human body,however,musculoskeletal melioidosis is uncommon and chest wall melioidosis is very rare. To determine the exact organism based solely on clinical presentation poses a great challenge to the physician.Yet,delay administration of antibiotic may be harmful.We describe a diabetic patient who had anterior chest wall melioidosis that mimics Staphylococcus aureus infection.A description of his presentation and management,along with a review of literature is presented. | Rashidi Ahmad Azhar Amir Hamzah Ahmad Kasfi Abdul Rahman Phee Kheng Cheah | 2010 | Asian Pacific Journal of Tropical Medicine2010，3，3： | 0 |
