| Abstract | 1. The antinociceptive effects of the delta opioid receptor selective agonist, DPDPE [(D-Pen2,D-Pen5)-enkephalin] was studied in rats aged postnatal day (P) 14, P21, P28 and P56. 2. Antinociceptive effects of DPDPE were measured as percentage inhibition of the C-fibre evoked response and post-discharge of dorsal horn neurones evoked by peripheral electrical stimulation. DPDPE was administered by topical application, akin to intrathecal injection. 3. DPDPE (0.1-100 microg) produced dose-related inhibitions at all ages; these inhibitions were reversed by 5 microg of the opioid antagonist naloxone. 4. The dose-response curves for C-fibre evoked response and post-discharge of the neurones were not different in rats aged P14 and P21. DPDPE was significantly more potent at P14 and P21 compared with its inhibitory effects on these responses at P28 and P56. 5. DPDPE produced minor inhibitions of the A-fibre evoked response of the neurones at P14, P21, P28 and P56, suggesting that the inhibitory effects of DPDPE are mediated via presynaptic receptors on the terminals of C-fibre afferents. 6. Since spinal delta opioid receptor density changes little over this period, the increased antinociceptive potency of DPDPE in the rat pups compared with the adult is likely to be due to post-receptor events, or in developmental changes in the actions of other transmitter/receptor systems within the spinal cord. |

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.
