Except for control group, rats in the other groups were intratracheally administered with bleomycin. Animals in pulmonary fibrosis model groups were sacrificed on day 3, 7, 14, 28 and 56. The sections of the right lung were stained by HE, Masson and sirius red. The left lung was weighed and its hydroxyproline content was assayed. The mRNAs of TGF-β1, MMP-9 and TIMP-1 in the lung homogenate were measured by semi-quantitative RT-PCR.

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

After 3-8 passages, the oral CAFs and the normal mucosa fibroblasts from tissue culture were observed under light microscope. Vimentin,α-SMA and Cytokeratin protein were detected by immunohistochemistry SP method on glass coverslips. VEGF, TGF-β1, MMP-9, Tenascin-C mRNA were analyzed by semi-quantitative RT-PCR.

用组织块培养法获得原代CAFs和正常粘膜成纤维细胞，0.25%胰蛋白酶消化传代和纯化细胞；通过形态学观察和免疫细胞化学染色对口腔CAFs和NMFs进行鉴定：采用半定量RT-PCR检测口腔CAFs和NMFs 4种基因的表达。

RESULTS: Light microscope showed that the collagen fibers arranged regularly in AECM with blankness of bone lacunas by HE, Mallory-Heidenhain rapid one-step dyeing and that the region around bone lacunas was stained different degrees of blue-green by Alcian blue dyeing.

结果 HE、Mallory- Heidenhain氏快速一步法染色后镜下可见AECM胶原纤维排列规则，骨陷窝空虚；阿利新蓝染色可见 AECM骨陷窝周边染色呈不同程度蓝绿色；免疫组织化学染色可见 FN和 L N的抗体染色阳性部位在细胞外基质。

The methods of sticking tissues piece to culture primary hFCECs and mouse 3T3 fibroblast conditioned medium to culture passage hFCECs were established;2.The Proliferative capacity of corneal limbus hFCECs is better than central hFCECs.3.3T3 conditioned medium could markedly promote the proliferation of epithelial cells

结论一、组织块贴壁法原代培养人胎儿角膜上皮细胞以及小鼠3T3成纤维细胞条件培养液传代培养方法基本建立；二、人胎儿角膜缘部上皮细胞增殖能力优于中央部；三、3T3细胞条件培养液能促进角膜上皮细胞的增殖。

RG has an inhibitory effect on the formation of liver fibrosis and cirrhosis. Its mechanism may be related to the improvement of hepatic function, decrease of serum TGF β1, collagen Ⅰ and Ⅲ and Hyp levels.

结论］软肝颗粒能改善肝组织病理变化，恢复肝功能，降低血清TGFβ1和Ⅰ、Ⅲ型胶原水平及Hyp含量，抑制肝纤维化、肝硬化的形成。

Light microscope observation showed that the growth of granulation tissue and collagen fibers of experimental group were much better than that of control group.

伤后7 d及14 d光镜观察发现实验组肉芽组织及胶原纤维生长优于对照组，14 d时实验组创面再上皮化的进程优于对照组。

They weren't aggressive, but I yelled and threw a rock in their direction to get them off the trail and away from me, just in case.

他们没有侵略性，但我大喊，并在他们的方向扔石头让他们过的线索，远离我，以防万一。
