Small intestinal biopsies showed subepithelial collagen deposition with varying degrees of villous atrophy and varying numbers of intraepithelial lymphocytes. Four patients had previous biopsies showing enteropathic changes without collagen deposition. Seven cases were associated with collagenous colitis and 1 also had features of lymphocytic colitis. Three patients also had collagen deposition in gastric biopsies. One case was associated with lymphocytic gastritis. Celiac disease (CD, gluten-sensitive enteropathy) was documented in 4 patients. Five patients made a clinical improvement with combinations of a gluten-free diet and immunosuppressive therapy. Two patients died of complications of malnutrition and 1 of another illness. Clonal T-cell populations were identified in 5 of 6 cases tested. Four of these patients improved clinically after treatment but 1 has died. Collagenous sprue evolved on a background of CD in 4 cases. There was no history of CD in others and these cases may be the result of a biologic insult other than gluten sensitivity.

小肠活检表现为上皮下胶原沉积，绒毛萎缩程度不一，上皮内淋巴细胞浸润数量不等。4例患者以往曾做过活检，表现为其他肠病改变，并没有胶原沉积。7例患者合并胶原性结肠炎，且1例还有淋巴细胞性结肠炎的特征。3例患者胃活检也发现有胶原沉积。1例患者合并淋巴细胞性胃炎。4例患者有乳糜泻（CD，谷蛋白敏感性肠病）病史。5例患者经无麸质饮食和免疫抑制治疗后，临床症状有所改善。2例患者因营养不良合并另一种疾病而死亡。6例患者做了T细胞受体基因重排，其中5例发现有克隆性T细胞群，这5例中有4例治疗后临床症状加重，且1例死亡。4例患者在CD的基础上病发胶原性口炎性腹泻；其余患者无CD病史，他们的发病也许是生物源性损害，而非谷蛋白敏感。

Results After used the SGS , the arrange of collagen tend to unifying , micrangiums are rich and in opening condition, the polymeride of pre-collagen accumulate in cytochylema in fibroblast, the total content of collagen is decreased, but the content of hPcⅢ is kept in a high level, the content of HA is increased gradually,which closes to the normal skin level.

结果 应用硅凝胶膜后，胶原排列趋于一致，微血管丰富而呈开放状态，成纤维细胞的前胶原聚合体蓄积在细胞浆内；胶原总的含量减少，但Ⅲ型前胶原含量维持在一个较高水平；透明质酸含量逐渐升高，接近正常皮肤水平。

Results The expression of vimentin in interstitial tissue, cytoplasm of interstitial cells, cytoplasm of Sertoli, cytoplasm of myoid cells were positive, not excepting cytoplasm of spermatogoniums.

结果 在染锰大鼠睾丸中除间质，间质细胞、支持细胞，肌样细胞细胞质波形蛋白表达阳性外，也有精原细胞的细胞质VM表达阳性。

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。

About 48%(90/194) were below 29 years of age. Ninety-nine of 194 cases had either radiotherapy alone or supplementary treatment with radiotherapy following surgery. We analyzed multiple prognostic factors. The factors of importance included postoperative radiotherapy; female in glioblastoma multiforme; the primary tumor dose above 5000 rads and/or whole brain irradiation in malignant astrocytoma and glioblastoma multiforme; the primary tumor dose above 4500 rads in ependymoma, medulloblastoma and oligodendroglioma; and spinal axis irradiation above 2000 rads in ependymoma and medulloblastoma that produced a better prognosis than in other groups.

男与女之比例为2.7比1，年龄分布自1至81岁，平均年龄33.3±19.3岁，中值年龄为34岁，29岁以下占48%(90/194)，其中99例单独或手术后辅以放射腺治疗，分析同种脑瘤的预后因素，其中多形神经胶母细胞瘤有手术后放射线治疗或女性，多形神经胶母细胞瘤合并星细胞瘤原发肿瘤剂量5000雷得以上或曾全颅腔照射，神经管胚细胞瘤，间胶质母细胞瘤，及室管膜瘤原发肿瘤剂量4500雷得以上，室管膜瘤及神经管胚细胞瘤有脊轴照射2000雷得以上预后均佳，且统计上有显著的差异。

This pattern is characterized by the combination of pro-MMP-2 and membrane type 1 (MT1)-MMP expression, which drie pericellular generation of actie MMP-2 and local degradation of normal lier matrix. In addition there is a marked increase in expression of TIMP-1 leading to a more global inhibition of degradation of fibrillar lier collagens by interstitial collagenases (MMP-1/MMP-13). These pathways play a significant role in the progression of lier fibrosis.

其降解肝正常基质，同时抑制引起肝纤维化的纤维胶原降解，这种情况的特点是前明胶酶A合成和膜型1－MMP表达，使得小叶内细胞激活MMP-2和降解当处的正常肝基质，此外血浆1型组织基质金属蛋白酶抑制剂（TIMP-1）明显升高引起广泛的抑制间隙胶原酶(MMP-1/MMP-13)对纤维肝脏胶原的降解。

At postnatal 1st week immunopositive reaction of NGF was detected mainly in sustentacular cells and the spermatogonia also showed positive staining. NGF positive staining in the testes was observed in interstitial cells, spermatogenetic cells, sustentacular cells and Leydig cells at 3rd week. After the postnatal 5th week, NGF-positive immunostaining was also detected in intersitial cells and spermatogenetic cells, but the intensity of reaction was weaker than that at 1st and 3rd weeks.

免疫组化定位分析显示：睾丸组织的神经生长因子蛋白表达于小鼠出生后的各个时期内，1周龄睾丸组织免疫阳性反应主要位于支持细胞，精原细胞也有着色；3周龄睾丸组织的间质细胞、各级生精细胞、支持细胞、管周肌样细胞表达均呈现阳性；5周后的睾丸组织内神经生长因子呈低水平表达，主要表达于间质细胞和生精细胞内。

The results were as follows: nanos 1 mRNA uniformly dispersed throughout the cytoplasm of oocytes at all stages. Strong expression of nanos1 mRNA was observed in oogonia and stageⅠ、Ⅱ oocytes, but the signal became weaker in later stage oocytes.

结果表明：在斑马鱼卵子发生中，nanos1 mRNA均匀分布于卵原细胞和各时期卵母细胞的胞质中；在卵原细胞和Ⅰ、Ⅱ期卵母细胞中，nanos1 mRNA的杂交信号十分强烈，而较晚期卵母细胞中信号明显减弱。

结果 Vimentin在原贴壁基质细胞系由原代传至 5代的细胞中，其表达逐渐下降，而在再贴壁基质细胞传至第 3代中表达最高；Desmin、α-SmoothMuscleActin单克隆抗体和VonWillebrandFactor抗体染色呈阴性。

The injured gill cells had a different ultrastructure, with endoplasmic reticulum dilated and vesiculated, mitochondrial cristaes partially disintegrated, gill fibre cuticles denatured and dropped. The ultrastructural damages to hepatopancreatic cells were characterized by the decrease of microvilli, swelling and breaking up of mitochondria, expansion of endoplasmic reticulum, disruption and vacuolization of nucleus, tumefaction of nuclear membrane and increase of lipid droplets. As for the toxicological changes of myocardial cells, the mitochondria were swelling, having a lot of vacuolus and disintegrating, while the myofibrils were irregular with endoplasmic reticulum dissolved.

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.
