Research shows that the extraction efficiency of CPZ can amount to 96% by twice extraction, while that of PCN is 77%. This system produces the distribution coefficients (KD) of 12.3 and 2.6 respectively for CPZ and PCN. Extraction mechanism is deduced according to ultraviolet and molecular fluorescence spectra variation of the drugs in the system studied.展开更多
目的:研究山药水提物(aqueous extract of Dioscorea batatas,DA)对四氯化碳(CCl4)造成的小鼠急性肝损伤的改善作用。方法:60只昆明小鼠随机均分为6组:正常对照组、造模组、阳性对照组(联苯双酯组)、不同提取工艺的山药水提物A、B、C组...目的:研究山药水提物(aqueous extract of Dioscorea batatas,DA)对四氯化碳(CCl4)造成的小鼠急性肝损伤的改善作用。方法:60只昆明小鼠随机均分为6组:正常对照组、造模组、阳性对照组(联苯双酯组)、不同提取工艺的山药水提物A、B、C组,用四氯化碳造成小鼠急性肝损伤模型,测定血清谷丙转氨酶(ALT)、谷草转氨酶(AST)、肝组织超氧化物歧化酶(SOD)活性、丙二醛(MDA)含量。肝组织常规HE染色观察。结果:各组肝损伤模型小鼠经山药水提物A、B、C及联苯双酯干预后,血清ALT、AST水平与造模组相比显著降低(P<0.05),肝组织中SOD活性升高,MDA含量降低(P<0.05),镜检观察山药水提物A、B、C及联苯双酯组小鼠肝组织病理切片,发现山药水提物A、B、C及联苯双酯组较造模组肝组织损伤坏死明显减轻,坏死灶减少,范围减小,粒细胞浸润减少,并且山药水提物A组较B、C2组干预肝损伤效果好。结论:山药水提物能明显改善CCl4所致急性肝损伤小鼠的肝功能状况,其作用可能与抗氧化清除自由基、和增强机体清除自由基的能力有关。展开更多
