Our results showed that the RnR was localized in the perinuclear zone and plasma membrane of the MCs.

本文旨在观察RnR在体外培养的大鼠肾小球系膜细胞(mesangial cells， MCs)和肾脏中是否表达，及其表达的细胞部位，并用RnR的多肽阻断剂肾素原&柄区肽&(handle region peptide， HRP)与RnR结合后观察受体复合物进入细胞的过程与定位。

For the application of 64 Codons, each step from DNA chain to mRNA chain, t RNA, ribosome, peptides, and to protein, has its specific permutable calculation model between chemical reactants and products, none of which has an objective permutable relationship with that in the 43 Table of Triplet Codes.

在生物遗传学的解释上，不预先测定给定生命体的 DNA 碱基顺序及其蛋白质的氨基酸顺序并把两者作比较，就把 DNA 和密码表两者指导合成的多肽链的氨基酸顺序称为该生命体遗传得来的氨基酸顺序，并以此将密码表称为生命的元素周期律在一切生命体中通用，是完全错误的。

Focal ischemia induced by photochemically thrombotic distal middle cerebral artery occlusion model to adult rats results in necrosis at the infarct core and activation of complex signal pathways for cell death and cell survival in the penumbra. The effects of ghrelin on regional cerebral blood flow in penumbra areas used by a laser Doppler Flowmeter.

本实验室前期工作初步证明ghrelin可保护谷氨酸及脂多糖诱导的原代培养大鼠脑皮质神经元的损伤，也能减少线栓大脑中动脉引起的脑梗塞体积，说明ghrelin对脑缺血引起的神经元损伤具有一定的神经保护作用，有可能成为一个内源性神经保护多肽，具有重要的理论价值和实践意义，值得深入研究。

Objective To extract and purify active polypeptides from the pilose antlers treated by various procedures and study their immunological function.

目的 提取并分离纯化不同加工方法处理的梅花鹿鹿茸活性多肽，并对其免疫功效进行初步研究。

The research determines the contents of ET and CGRP in EH patients blood plasm...

本研究测定了一组EH患者血浆ET和CGRP的含量，并观察口服缬沙坦对这两种多肽的影响。

The plerosis of articular cartilage injury is an important task in the aspects of clinincal and basic research on orthopaedics.

IGF-Ⅰ是一种由70个氨基酸组成的多肽，分子量为7.6kDa，其结构与胰岛素同源，受生长激素调节。

Both Fas and NO can lead chondrocyte apoptosis respectively and cause articular cartilage destruction. IGF-Ⅰ, TGF-β, bFGF, BMP and other growth factors are polypeptide agents that can influence cell activity by signal convection. They can accelerate chondrocyte proliferation and proteoglycan synthesis, play the local regulation action on formation and plerosis of bone and cartilage tissue by autocrine or paracrine. They have the ability to induce cartilage formation. Some investigations showed that growth factors can influence chondrocyte metabolism, synthesis of specific Ⅱ type collagen and proteoglycan by co-operation and inhibition. 1. 3 Situation of OA therapeutics The therapeutic methods of OA mainly comprised non-drug treatment, drug treatment, operation treatment, tissue and genetic engineering, et al. Drug treatment is the chief method among them.

若其活性发生改变，则将导致关节软骨基质成分的丢失和进行性破坏；软骨细胞凋亡与OA的发病密切相关，Fas与NO可各自独立介导软骨细胞凋亡，造成关节软骨破坏；IGF-Ⅰ、TGF-β、bFGF、BMP等生长因子是一组通过细胞间信号传递影响细胞活动的多肽因子，具有促进细胞生长、增殖与合成等作用，可通过自分泌或旁分泌方式对骨和软骨的形成和修复起局部调节作用，可促进软骨细胞增殖、分化与蛋白多糖的合成，具有较强的诱导软骨形成的能力，研究表明多种生长因子相互促进、相互抑制，以协同或拮抗方式影响软骨细胞代谢，影响软骨细胞特异性Ⅱ型胶原和蛋白多糖的合成分泌。
