Osteoblast marker (alkaline phosphatase, osteocalcin mRNA, calcium node), adipocyte marker (lipid droplet, PPAR γ-2mRNA) and neural cell-like marker (nissl body, neuron specific enolase, neurofilament protein) were respectively determined by the immunohistochemical method, polymerase chain reaction and immunocytochemical method.

Methods: 5% propranolol emulsion was applied externally on the back of a guinea pig\' s ear to produce the psoriasis-like dermatitis model to observe the effects of Baibi ointment on the histopathological changes of the model.Radioimmunoassay was used to observe the levels of cytokines like IL-2、IL—6 and IL-8, and the effects of the ointment to the cytokines. MTT method was used to study the effects of the extracts of the Baibi Formula and the extracts of its main components Huangjing , Kushen , Dahuang ,Huangbai, to the multiplication of HaCaT cells—one of the Malpighian cell line with and without stimulation of TNF-α.

实验采用5%心得安乳剂建立豚鼠银屑病样皮炎模型，观察白疙软膏对豚鼠银屑病样皮炎模型组织病理改变的影响；采用放射免疫法检测豚鼠银屑病样皮炎模型皮损中细胞因子IL-2、IL-6、IL-8的水平，观察白疕软膏对豚鼠银屑病样皮炎模型皮损中细胞因子的影响；采用MTT法研究了中药白疕方提取液及白疕方主要组成药物大黄、黄柏、黄精、苦参提取液对角质形成细胞系HaCaT细胞增殖的影响及对TNF-α刺激后的角质形成细胞系HaCaT细胞增殖的影响。

在肿瘤的新生血管形成过程中，内皮细胞起决定性的作用，这些内皮细胞一部分直接来自肿瘤组织内原有血管的内皮细胞的芽生生长，一部分来自于骨髓内的内皮祖细胞的动员和释放［2］。

No callus could be induced from leaf or petiole explants of varieties F30 and Ⅱ cultured on MS medium if supplemented alone with 6-bezyladenine （6-BA） or thidiazuron, or kinetin. However, the calli were induced on MS medium containing 2.0 mg L-1 6-BA and 0.5 mg L-1 NAA （α-naphthaleneacetic acid）, and the calli derived from petioles of variety Ⅱ could produce redifferentiated shoots, but of variety F30 could not. The later could only produce shoots directly from the base of the petioles.
