- 本文提出了用硝酸鋁絡(luò )合分光光度法測定芹菜中總黃酮時(shí)會(huì )因為NaNO2-AL(NO3)3-NaOH使非黃酮類(lèi)物質(zhì)顯色而造成測定出現誤差。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.
- 經(jīng)不同氮源利用的鑒定 ,89 33%屬于nitA ,9 33%屬于nitB ,1 33%屬于nitC ,其中nitC在以NaNO2 作為唯一氮源的MO2 培養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依劑量地使SDL延長(cháng)13.7%~105.3%,使逃避潛伏期縮短40.0%~60.0%,使迷宮覓食時(shí)間減少28.3%~49.4%,并能明顯改善NaNO2或乙醇引起的記憶損害;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 ,通過(guò)水迷宮實(shí)驗檢測小鼠學(xué)習記憶能力 ,生化法測腦內膽堿酯酶(AchE)、超氧化物歧化酶 (SOD)含量 ,并進(jìn)行腦組織冠狀切片和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;
