- 本文提出了用硝酸铝络合分光光度法测定芹菜中总黄酮时会因为NaNO2-AL(NO3)3-NaOH使非黄酮类物质显色而造成测定出现误差。NaNO2-AL(NO3)3-NaOH colorimetry for determination of flavonoids in celery extract would bring error because of poor special reaction with flavonoids was indicated in this paper.
- 经不同氮源利用的鉴定 ,89 33%属于nitA ,9 33%属于nitB ,1 33%属于nitC ,其中nitC在以NaNO2 作为唯一氮源的MO2 培养基上被完全抑制致死。According to their phenotypes on the media containing only one of the three different nitrogen sources respectively,89.33%25 were identified as nitA, 9.33%25 were nit B and 1.33%25 nit C. The mutant nit C was found inhibited into death by the nitrite.
- EEA 2~8 ml/kg依剂量地使SDL延长13.7%~105.3%,使逃避潜伏期缩短40.0%~60.0%,使迷宫觅食时间减少28.3%~49.4%,并能明显改善NaNO2或乙醇引起的记忆损害;EEA 2-8 ml/kg lengthened SDL by 13.7%25-105.3%25, shortened EL by 40.0%25-60.0%25 and food-hunting time by 28.3%25-49.4%25, in a dose-dependent manner. EEA reversed ethanol-induced disturbance of memory retrial in a passive avoidance and NaNO2-induced disruption of memory retention in a passive avoidance and maze.
- 方法 :采用腹腔注射D Gal+NaNO2 的方法造模 ,通过水迷宫实验检测小鼠学习记忆能力 ,生化法测脑内胆碱酯酶(AchE)、超氧化物歧化酶 (SOD)含量 ,并进行脑组织冠状切片和HE染色。Methods:The mice model were established by intraperitoneal injection of D Gal+NaNO 2; the capacity of learning and memory was tested on all mice with water maze; levels of acetylcholinesterase (AchE) and superoxide dismutase(SOD) of brain tissues were assayed by biochemical methods;
