The organization fixing of apoenzyme subtypes by IHC: The most increasing expressing were cPLA_2 and sPLA_2 in pancreas, they were found all over in the pancreatic acinar cells in 6h after PT, and spread out from the cells in 24h,then decreased after 72h.

用IHC技术对酶蛋白亚型组织定位方面：胰腺内的表达以sPLA_2和cPLA_2增加为主，6h时即遍布于胰腺腺泡细胞；24h时由于胰腺细胞的大量破坏，腺泡细胞外均可见sPLA_2和cPLA_2的高表达；72h后细胞内外sPLA_2和cPLA_2逐渐下降。

RESULTS AND CONCLUSION: Osteoblast was fusiformed-shaped and had plentiful processes. Nucleus was orbicular-ovate and leaning to lateral side. Soma was large, and plasma was abundant. Alkaline phosphatase staining suggested that a great number of gray-black particles were observed in plasma, and some region was darkly stained.

The positive expression rates of Tissue Inhibitors of Metalloproteinase-2 protein in the cases of involuting groups were significantly higher than those in proliferating group and vascular malformation groups and normal skin group (P.05). Its difference was significant. Conclusions: Matrix MetallProtinase-2 and Tissue Inhibitors of Metalloproteinase-2 may play an important role in the pathogenesis of hemangiomas through angiogenesis. They may have no effect on vascular malformation and normal skin

血管瘤退化期，TIMP-2表达明显升高，说明 TIMP-2与血管瘤纤维化、消退有关，其机制可能是一方面通过抑制MMP-2介导的基底膜降解而在内皮细胞迁移、聚集中起作用，另一方面直接抑制内皮细胞的增殖及迁移，使内皮细胞高频率调亡，细胞外基质增多，组织出现纤维化，最终导致血管瘤的退化。2、血管畸形和正常皮肤小血管中MMP-2和TIMP-2不表达或表达较弱，说明血管畸形和正常皮肤小血管中并不存在异常的血管生成，据此可以对血管性疾病进行分型、分期，并指导临床治疗。

The two species are similar in stomatal character and in the absence of accessory transfusion tissue, but they are very different in stomatal distribution, pinna venation pattern and pinna marginal shape, presence or absence of mucilage canal, differentiation of palisade and spongy parenchyma, characteristics of girder parenchyma and epidermal anticlinal wall.

两个属在气孔器特征与不具副传输组织方面极为相似，而在气孔的分布、羽片脉序式样与叶缘形态、粘液道的有无、海绵组织与栅栏组织的分化、工字厚壁组织与表皮细胞垂周壁特征方面则有较大的差异。

No immunostaining was seen in RPE. Double staining that Kir2. 1 and glutamine synthetase, Kir2. 1 and glutamine synthetase colocalized well. Intense Kir7. 1 immunolabeling was present on the apical surface of all RPE cells and appeared to extend over the length of the apical processes. Na〓, K〓-ATPase expression varied among RPE cells, but in highly expressing cells, it co-localized with Kir7. 1. Immunoreactivity of Kir2. 1、Kir4. 1 and Kir7. 1 acomplished by ABC immunohistochemistry in monkey and human retinae got the nearly same results as bovine.

间接免疫荧光组织化学显示，Kir2.1蛋白主要分布在Müller细胞与神经元相接触的细胞膜区域；与Müller细胞的特异性标记蛋白质抗谷氨酸合成酶抗体双重标记显示其分布特性重叠，在RPE未检测Kir2.1蛋白的免疫活性存在；Kir4.1蛋白集中分布于Müller细胞的内侧突起，与GS蛋白双重标记显示其分布特性重叠，RPE未检测Kir4.1蛋白的免疫活性存在；Kir7.1主要分布于RPE游离面及其突起的全长，与特异性标记RPE突起的Ezrin蛋白完全重叠，Na〓-K〓ATP酶在不同部位的RPE表达不同，Na〓-K〓ATP高表达的RPE细胞与Kir7.1的分布特性重叠。
