Objective To explore the structural foundation of the releasing pattern and extracellular normal transport route for secretory granules of polypeptide hormones of neurohypophysis.

目的 探讨神经垂体多肽激素分泌颗粒的释放形式和在细胞外正常转运途径的结构基础。

OBJECTIVE: To provide the morphological evidences for the structural foundations of the releasing pattern and extraeellular normal transport route for secretory granules or polypeptide hormones of neurohypophysis by observing the structure of rats' neurohypophysis.

目的：通过观察大鼠神经垂体的结构特征，为神经垂体多肽激素分泌颗粒的释放形式和在细胞外正常转运途径的结构基础提供形态学依据。

BACKGROUND: The basic way for the releasing pattern of secretory granules of neurohypophysis is still not clear, neither is the extracellular normal transport route of neurohypophysis polypeptide hormones to enter the cerebrospinal fluid.

背景：神经垂体多肽激素分泌颗粒的释放形式和在细胞外正常转运途径的结构基础是以胞吐分泌方式还是浓度差因素影响而进入脑脊液的。

The releasing pattern of secretory granules or polypeptide hormones of neurohypophysis involves a whole-releasing pattern together with granular membrane. After released into perivascular space, they enter easily into cerebrospinal fluid via interspace of tissue and epithelial openings rather than into blood circulation through the walls of capillaries, and then into the cerebrospinal fluid.

神经垂体多肽激素分泌颗粒的释放形式，存在一种连同颗粒被膜的整体释放；释放入血管周隙内的多肽激素或分泌颗粒，更易经组织间隙、囊上皮孔进入脑脊液，而非直接透过毛细血管壁进入血液循环再进入脑脊液中。

The results showed that the optimum enzymatic conditions were: choosing papain, with substrate concentration 16%, enzyme concentration 4000U/g, hydrolysis time 6h, and the optimum conditions for the enzymatic hydrolysate of porcine blood to synthesize nitrosyl heme-polypeptide were: NaNO2 added 1.6%, pH5.00 and reaction time to 12min at 55℃.

试验表明，以选用木瓜蛋白酶效果较好，最佳酶解条件为：底物浓度16%，加酶量4000U/g，水解时间6h；酶解液合成色素最佳参数为：pH5.00，反应时间12min ，反应温度为55℃，NaNO2 的添加量为1.6%。

The expression and axonal transport of pituitary adenylate ecelase-activing polypeptide was reported, The number of neurons immunoreactive for PACAP increased markedly within the nodose ganglion during a 24-48h culture period, PACAP was found to axonally transported and accumpulated at the site of a crush injury.

另有一个研究，是调查在体外培养的鼠迷走神经中垂体腺苷酸环化酶激活多肽的表达和轴突输送，提出在24-48小时的培养期，PACAP免疫反应性神经元的数目在结节神经节内显著地增加，PACAP参与轴突输送中并堆积在受损部位，在这部位被释放。

Comparing with the structure of heme group that covalently linked to the polypeptide chain in natural heme proteins, we simulated the covalent modification of artificial Fe-salophen complex with amino acid histidine or dipeptide cysteinyl-histidine, with the intention of providing useful information for design of metalloproteins containing nonnatural prosthetic group.

通过比较天然血红素蛋白中血红素与多肽链进行共价连接的结构，我们对组氨酸或二肽半胱氨酰-组氨酸共价修饰人工配合物Fe-salophen进行了计算机模拟，旨在为设计包含非天然辅基的金属蛋白分子提供有用的信息。

The theory is based on two methods to show that initial folding sites occur among nonpolar groups in a polypeptide chain.

该理论是基于两种方法的基础上提出的，指出蛋白最初的折叠位点出现在多肽链的非极性基团处。

These two methods were used together in this study to pinpoint where on a polypeptide chain the nonpolar segments occur and where initial folding takes place and then propagates to the final folded form.

这两种方法合起来运用到研究中，可以查明肽链上非极性片断的位置、最初折叠发生的地方，和最终折叠形成的形式。

An enzyme of pancreatic juice that hydrolyzes proteins to form smaller polypeptide units.

这种形式的投资是为你的孩子提供日后经济保障的上好方法。

This paper discusses design and realizable methods of remote test output interface from logical design angle.

本文从逻辑设计的角度讨论遥测输出接口的设计及实现方法。
