The results showed that ZBC can improve the rats mental state, diet, hair, increase their body weight,decrease remarkably ALT, AST, and GGT activity, raise ALB content and A/G, decrease the levelof serum HA, LN, PC III and IV-C, and decrease Hyp content of liver tissue, restrain mRNA expression of III collagen, relieve remarkably the inflammalion damage, fatly degeneration of the liver cells, and reduce the collagen fibre of the liver.

枳鳖胶囊可明显改善肝纤维化大鼠的精神状态、饮食、毛色泽，增加其体重；显著降低血清AST、ALT、GGT，显著升高血清ALB、A／G；降低血清HA、LN、PCⅢ、Ⅳ-C和肝组织Hyp含量；明显减轻大鼠肝细胞损害、肝脏脂肪变性和胶原纤维增生的程度；抑制Ⅲ型胶原mRNA的表达。

RESULTS The degenerative changes of nerve ending in Meissner's corpuscles were observed after 1 month of denervation, and the basic structure of the corpuscles had no obvious changes. After 3 months, the axons of corpuscles were disappeared, and the volume of corpuscles was shrunk. The basic structure of nerves was disappeared, and the lemmocyte and neurolemma plate were changed after 5 months.

结果 失神经1个月时触觉小体内的神经末梢已有溃变，触觉小体的基本结构无明显改变；3个月时轴突消失，触觉小体的体积开始萎缩；5个月时神经结构消失，膜细胞及其膜板亦开始改变；8个月时触觉小体内胶原纤维含量逐渐增多；12个月时触觉小体内膜结构与膜间基质完全消失，被胶原纤维代替。

Many factors may be involve in the course. To investigate the regulation activity of mesenchymal cells to differentiation of epithelial cells from hair follicle and to study its differentiation property, mesenchymal cells gel was made by nubby dermal papilla cells, free dermal papilla cells, skin fibroblasts. Skin keratinocytes and epithelial cells from hair follicle were inoculated on the gel surface and cultured in air-liquid interface. Three-dimensional model of DPC using to induce epithelial cells differentiation is built in vitro.

为了进一步研究毛囊细胞间的相互作用，探讨毛囊间质细胞对毛囊上皮细胞分化的调节作用，研究毛囊上皮细胞的分化特性，我们利用团块状的毛乳头细胞，游离分散的毛乳头细胞或皮肤成纤维细胞制成间质细胞胶原凝胶，表面接种皮肤角质形成细胞或毛囊上皮细胞，进行气-液界面培养，在体外建立了毛乳头细胞诱导毛囊上皮细胞分化的立体模型。

Fig.1 SHEE cultured on coverslide, the living cells were growing in single layer with rich cytoplasm, the nuclei were uniform in size with a nucleolus ph ×400 Fig.2 SHEE had a nucleus with ellipse shape, large nucleolus and the cytoplasm contained mitochondria and tonofibrilEM ×10 000 Fig.3 SHEE was spherical in shape, with pseudopods attached on petri dish and abundant villi on cell surface SEM ×5 000 Fig.4 Same as in Fig.3, cell attached on petri dish, appeared stellate or polygonal in shape, with abundant pseudopods and cytoplasmic processes. Protrusive nuclear region in central part of the cell had more micro-villi SEM ×5 000 Fig.5 Chromosomes of SHEE cells belonged to diploidy type Giemsa ×1 000 Fig.6 The SHEE cells of stained in dark brown by Ki67 immunohistochemistry were the proliferative cells Immunohistochemistry ×400 Fig.7 In SHEE cell culture, the nucleus stained red or pink by PI was dead cell, the green nucleus was living cell Fluorescent ×400 Fig.8 The cell labeled by TdT was apoptotic cell in which the chromatin of nucleus condensed in block, a pyknotic nucleus in the upper right conner was seen TdT labeled ×400
