| Abstract | To investigate the effect of nitric oxide (NO) on the expression of apelin receptor mRNA, as well as their correlation, in the caudate nucleus of rat.L-Arginine (L-Arg), N $^{ G }$-nitro-L-arginine methyl ester (L-NAME) and normal saline (NS) was separately microinjected into rat caudate nucleus. Expressions of neuronal NO synthase (nNOS) mRNA and apelin receptor mRNA were detected by RT-PCR at 4, 8, 12, 24 and 48 h after microinjection, and their correlation was determined.The expressions of nNOS mRNA and apelin receptor mRNA were both significantly increased after microinjection of L-Arg, but significantly decreased after microinjection of L-NAME compared with the NS control group. The nNOS mRNA had a positive correlation with the expression of apelin receptor mRNA after microinjection of L-Arg and L-NAME.The activity of NOS in the central nervous system, especially in the caudate nucleus, is one of the key factors for NO to exert many kinds of biological actions, such as modulation of central pain, as a neurotransmitter. The neurobiological action of NO in rat caudate nucleus may be associated with apelin receptors.研究大鼠尾核内一氧化氮(nitric oxide, NO)的作用机理及其与apelin 受体mRNA 表达的相关性。大鼠尾核内微量注射NO前体L-精氨酸(L-Arg)、 N $^{ G }$-硝基-L-精氨酸甲酯(N $^{ G }$-nitro-L-arginine methyl ester, L-NAME)和生理盐水(NS), 应用逆转录-聚合酶链反应(RT-PCR)检测大鼠尾核给药4、 8、 12、 24 及 48 h 后一 氧化氮合酶(neuronal nitric oxide synthase, nNOS) mRNA 和 apelin 受体 mRNA 表达的变化及二者的相关性。注射 L-Arg 后大鼠尾核nNOS和apelin受体的mRNA表达明显升高, 注射 L-NAME 后大鼠尾核nNOS和apelin 受体mRNA表达明显降低, 且均有统计学意义。 注射L-Arg 和L-NAME 后, nNOSmRNA 和 apelin 受体 mRNA 的表达呈正相关。在中枢神经系统, 尤其是在尾核中, NOS的活性是 NO 作为神经递质或调质参与包括 中枢痛觉调制作用在内的多种生物学作用的关键因素之一, 尾核内NO的神经生物学作用可能与apelin受体作用相关。 |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
