遵循生态规律,构建生态课堂   总被引：5，自引：0，他引：5  

袁聿军 《生物学教学》2006,31(7):17-19

生态学是研究有机体与周围环境相互关系的科学。把生态学原理运用到课堂教学中，对构建真实的课堂，而不是一个经过筛选的虚假的环境，具有重要的指导意义。本文将以生态学的视角，对构建生态课堂进行初步的探讨，以期让课堂充满着生机与活力。  相似文献

罗本燕  徐增斌  陈智  陈峰  唐敏 《浙江大学学报(A卷英文版)》2004,5(8):989-994

Objective: To construct a PC12 cell strain with neuronal differentiation, and observe the apoptosis and pro-liferation activity effects induced these cells by Amyloid beta-Protein (Aβ-43). Methods: 1) PC12 cells in logarithmicgrowth phase were subcultured for 24 h. After the culture fluid was changed, the cells were treated with Rat-β-NGF andcultured for 9 days. 2) Neuronal differentiation of PC12 cells in logarithmic growth phase were divided into four groups:control group (0), experimental group (1), experimental group (2) and experimental group (3). The concentrations of Aβ inthe four groups were 0 μmol/L, 1.25 μ mol/L, 2.5 μ mol/L and 5 μmol/L, respectively. The cells were harvested at 24, 48 and72 h later and stained with AnnexinV-FITC/PI after centrifugation and washing. Then flow cytometry was conducted toexamine the apoptosis percentage. 3) NGF-induced PC12 cells were selected and Aβ with different concentrations wasadded. The final concentrations of Aβ were 0 μmol/L, 1.25 μmol/L, 2.5 μmol/L and 5 μ mol/L, respectively. After the cellswere incubated in an atmosphere of 5% CO2 at 37 ℃ in an incubator for 72 h, the OD values were examined. Results: 1)Neuronal differentiated PC 12 cell lines were successfully established. 2) Flow cytometric examination indicated that Aβ(1.25, 2.5, and 5.0 μmol/L) could effectively induce apoptosis of neuronal-differented cells at the 24 h, 48 h and 72 h timepoints. 3) Aβ (0-5.00 μ mol/L) had no obvious effect on proliferation or restraining of the neuronal differentiation of thePC 12 cells after a 72 h interacting process. Conclusion: This investigation revealed successful neuronal differentiation of thePC12 cell strain. The induction of apoptosis of the neurocytes by various concentrations of Aβ was observed and the in-fluence of Aβ on induced proliferation of PC 12 cells by Rat-β-NGF was revealed. This study -05 provide basis for futureresearch on the molecular cure of AD and interdiction of AD evolution.  相似文献

Relationship between the size of pontocerebellar angle tumor and audiology     

Tang Jian-guo  Cai Yi 《浙江大学学报(A卷英文版)》2001,2(1):111-113

Objective: To study the relationship between the size of pontocerebellar angle tumor and audiology. Methods: Retrospective analysis of accoustically evoked brainstem response (ABR) waveforms and pure tone threshold in 27 subjects with tumor of pontocerebellar angle. Results: ABR wave forms and pure tone threshold were significantly affected statistically by the size of tumors, especially those tumor larger than 3 cm in diameter. Conclusion: The primary symptom of the patient was unilateral hearing loss. Early discovery of the lesion is important and ABR is a sensitive tool for early diagnose of the tumor.  相似文献

创建学习型学校的理性思考     

张扬群  汤光亮 《成都教育学院学报》2006,20(3):22-24,78

学习型学校是指通过培养教师的自主学习和团队学习,形成学校浓厚的学习气氛,进而充分发挥教师的创造性思维能力,为实现学校的共同愿景而创造性工作的学校。马克思主义哲学是创建学习型学校的哲学依据,彼得·圣吉的学习型组织理论是创建学习型学校的理论依据。新时代对教育“挑战”使我们认识到:创建学习型学校是建设学习化社会的需要,是提高办学水平的需要,是提高教师素质的需要。创建学习型学校应树立现代化的学习理念,营造学习型校园文化,建构灵活高效的学习机制,确立学校共同发展的愿景,建立自主管理机制,构筑学习评价体系。  相似文献

INTRODUCTION During the development of printing technology, digital printing has played an important role. Now various kinds of multi-color digital inkjet printers are available. Compared with the conventional digital inkjet printer, the multi-color digital inkjet printer has larger color gamut and can faithfully produce more colors. The conventional color printing devices nor- mally use three or four inks, e.g., CMY, CMYK. Although some adopt more than four inks, e.g., CMYKLcLm, the…  相似文献   

国际性行政体制探析     

黄玉君 《台州学院学报》2002,24(1):7-10

相对于一国政府的行政体制而言,国际性行政体制具有跨国性和非主权性的特点,这也就决定了国际性行政体制独特的运行方式。二战后,以联合国为代表的国际性行政体制有了大规模的发展,呈现出多样化趋势。冷战结束后,国际性行政体制的变革引人注目,各类国际机构不断调整自我,以适应国际合作和国际竞争的需要。  相似文献
