四种不同品系大花君子兰的离体组织培养研究

以四种不同品系大花君子兰的幼子房为外植体进行了离体组织培养研究.结果表明:大花君子兰幼子房愈伤诱导和分化成苗的能力与品系、外植体时期、光照强度、低温处理时间、植物生长调节剂种类和质量浓度及酸水解酪素质量浓度等有关.愈伤诱导的最佳培养基为MS+蔗糖35g/L+酸水解酪素0.4g/L+BA 1.0mg/L+NAA 1.0mg/L+2,4-D 2.0mg/L;分化成苗的最佳培养基为MS+蔗糖35g/L+NAA 0.5mg/L+KT 3.0mg/L;生根的最佳培养基为1/2 MS培养基.

An Enzymologic Study on Bone Marrow Cells in Patients with Aplastic Anemia Treated by Supplementing the Kidney and Removing Blood Stasis

The content of cytochrome oxidase (CCO), succinate dehydrogenase (SDH) and neutrophil alkaline phosphatase (NAP) in bone marrow cells in 68 cases of aplastic anemia before and after treatment was determined by computerized graphical analysis and compared with that of normal volunteers (control group). The significantly lowered CCO and SDH levels and the markedly increased NAP content before treatment (P<0.01) became approximately normal after that of supplementing the kidney and removing blood stasis (P >0.05).
