One eye in patients was selected to do the tear film breakup time, Schirmer test and cornea fluorescein staining, and the expression of NFκB and TGFβ1 on bulbar conjunctiva endepidermis was detected by immunohistochemistry.

TGFβ1是多功能细胞因子，对上皮细胞具有较明显的抑制作用，对成纤维细胞及其他间叶组织来源的细胞均具有明显的刺激作用，表现为胶原合成增加，有利于组织修复及伤口愈合［3，4］。

Using cytohischemical staining methods, with the results of comparison the dynamics of proteins and polysaccharides in the anthe wall cells and colule cells of different developmental phases in female and male flowers, the anormogenesis of anther tapetum in the inflecting phase of from bisexual flower to unisexual flower was observed. In microspore developed phase, the tapetum functions of preserving and transportingmutritive material for microspore development and of secreting callosal enzyme for decompositing callosal cell lost no normal guadrant formed, of being abnormal meiose of pollen mother cells, and then, the stamen aborted selectively in female flowers and pistil in male flower.

利用细胞组织化学染色技术，对雌、雄花雄蕊花药壁细胞及花药内细胞发育过程中多糖及蛋白质动态进行了比较，实验中观察到雌花在从两性至单性花转变时期雄蕊绒毡层在整个发育过程中表现异常，在小孢子发育过程中未能起到贮藏、转运营养物质供小孢子发育及适时分泌胼胝质酶溶解胼胝质壁的功能，并且花粉母细胞减数分裂异常而未形成四分体结构，进而导致雌花雄蕊选择性败育，而雄花中雌蕊组织也发生了选择性败育过程。

The inflammation reaction hyperplactic stage and lymphatic nodular stage are of nonspecific morphological changes and should be diagnosed with the help of positive tuberculin test and obvious increase of adenosine deaninase ; tuberculous nodular stage has a great number of epithelioid cells,and Langhans cells, caseous necrosis stage is characterized by a great deal of necrotic tissue and debris,a small number of fragmented epithelioid cells

炎性增殖反应期非特异性形态学变化，需要结合结核抗体阳性和腺苷酸脱氨酶明显增高有助于诊断，结核结节期主要可有较多类上皮样细胞及郎罕氏细胞；而干酪样脓样坏死主要见大量坏死组织及碎屑、少数残碎不全类上皮样细胞，此期主要能查到抗酸菌为特点；纤维增殖期，抽出物难取，仅见少数纤维组织、纤维细胞和黏液间质为其特征，提示结核恢复、瘢痕形成所致。

Hepatic chymase concentrations in S3 and S4 cases were greater than in S1 and S2,〔53+54=(31.3±24.6)ng/mg vs. S1+S2=(5.7±4.8) ng/mg, P.01〕. Cells immunoreactive for chymase were seen throughout portal areas and intralobular sinusoidal walls, largely colocalizing with fibrosis. Chymase appears to be involved in hepatic fibrosis in chronic hepatitis.

慢性肝炎纤维化分期重的S3和S4患者，其肝组织中Chymase浓度〔S3+S4=(31.3±24.6)ng/mg〕明显高于纤维化轻的S1和S2患者〔S1+S2=(5.7±4.8)ng/mg〕，P.01；免疫组化染色结果，Chymase标记的肥大细胞主要分布于纤维化旺盛的汇管区与类洞壁，其分布与纤维化部位相一致，且肝组织中Chymase浓度高的患者，其肝组织内Chymase标记的肥大细胞分布增多推测肝组织中Chymase浓度可能与慢性肝炎肝纤维化关系密切。

In the normal uterus, Cytokeratins immunolabelling were detected in glandular cell, luminal epithelial cell, Vimentin immunolabelling were detected in stromal cell and endoblastic cell; CK7 immunolabelling were not detected in any tissue of the yak utenus.

研究结果显示：未妊娠时，泛角蛋白在子宫内膜腺上皮细胞、腔上皮细胞内表达，波形蛋白在子宫内膜基质细胞内表达，平滑肌肌动蛋白在子宫平滑肌和血管平滑肌内表达，牦牛子宫任何部位均不表达角蛋白7；妊娠30天左右时，泛角蛋白在子宫内膜腺上皮细胞、子宫内膜腔上皮细胞、滋养层细胞、内胚层细胞和尿囊细胞内表达，波形蛋白在子宫内膜基质细胞和内胚层细胞内表达，平滑肌肌动蛋白在子宫平滑肌和血管平滑肌内表达，角蛋白7在尿囊细胞内表达，偶尔在腔上皮细胞的细胞核边缘表达；消化法进行原代培养时，组织经胶原酶消化并通过100目和400目筛网组合可以有效地分离原代子宫内膜基质细胞和子宫内膜腺上皮细胞；分离得到的子宫内膜基质细胞活率达90%以上，并可在体外传代7次以上；分离得到的子宫内膜腺上皮细胞活率可达85%以上，并可在体外传代5次以上；RPMI1640培养基最适合子宫内膜基质细胞和子宫内膜腺上皮细胞的生长，维持子宫内膜基质细胞正常生长的FBS添加量为20%，维持子宫内膜腺上皮细胞正常生长的胎牛血清添加量为30%。

In four patients with bilateral total corneal stem-cell deficiencies, 3-by-3-mm specimens of oral mucosal tissue were harvested, and the harvested cells were cultured for two weeks with 3T3 feeder cells that had been treated with mitomycin C. Conjunctival fibrovascular tissue was surgically excised from the ocular surface, and sheets of cultured autologous cells were transplanted directly to denuded corneal surface of one eye of each patient, without using sutures.

在4位双侧干细胞完全缺失的病患，取下3乘3的口腔黏膜组织样本，而且被取下的细胞与使用3T3细胞铺成的细胞层以mitomycin C处理，共同培养2个星期；结膜纤维血管组织利用外科从角膜表面切除，而且培养的自体细胞直接地移植到每位病患一只眼睛裸露的表面，不需要缝合。

Generally we think muscular histogenesis has many steps of biology, including foetal mesoderm merotomy; myoblast shapes in arthromera; myoblast can form muscular tissue to move to limbs; the proliferation of sarcoblast can increase cells\'quatity.

一般认为，肌组织发生是一多步骤的生物学过程，包括胚胎中胚层的分节；成肌细胞在体节形成；成肌细胞向四肢迁移形成肌组织；成肌细胞增殖以增加细胞数量。

Mesenchymal stem cells are multipotent cells derived from many adult tissues, which can differentiate into cells of the mesodermal lineage, such as adipocyte, osteocyte and chondrocyte, as well as cells of other embryonic lineages. They are a promising tool for tissue engineering.
