The results showed that the callus initiation and plant regeneration were related to endogenous hormones of mature rice embryO and its derived callus. Improving the balance of endogenoushormones through adjusting exogenous hormones of media is a effective means of raising culture efficiency.展开更多
目的研究稀莶草（Siegesbeckia orientalis L．）甲醇提取物对成纤维细胞增殖及对大鼠创伤的修复作用。方法体外培养乳鼠真皮成纤维细胞，加入不同浓度的稀莶草提取物，MTT法观察其对细胞增殖的影响；制备大鼠切除伤模型，观察稀莶草提...目的研究稀莶草（Siegesbeckia orientalis L．）甲醇提取物对成纤维细胞增殖及对大鼠创伤的修复作用。方法体外培养乳鼠真皮成纤维细胞，加入不同浓度的稀莶草提取物，MTT法观察其对细胞增殖的影响；制备大鼠切除伤模型，观察稀莶草提取物对大鼠实验性创伤的修复作用。结果浓度为50～200μg·mL^-1的稀莶草提取物对成纤维细胞的增殖作用显著；稀莶草甲醇提取物外涂对实验性大鼠皮肤损伤有加速修复作用。结论稀莶草具有促伤口愈合作用，其促修复作用可能与促进成纤维细胞增殖有关。展开更多
