| Abstract | It has been shown for the first time that biogenic amines (catecholamines and tryptophane derivatives) stimulate dose-dependently activity of adenylyl cyclase (AC) and GTP-binding of G-proteins in muscle of the skin-muscle sac of the earthworm Lumbricus terrestris. By efficiency of their stimulating action on the AC activity, biogenic amines can be arranged in the following sequence: octopamine > tyramine > tryptamine ≈ serotonin > dopamine > isoproterenol ≈ adrenalin. The sequence of efficiency of their action on GTP-binding is somewhat different: serotonin > tryptamine > octopamine > dopamine ≈ tyramine > adrenaline > isoproterenol. Sensitivity of AC and G-proteins in the worm muscle to biogenic amines is similar with that in smooth muscle of the mollusc Anodonta cygnea (invertebrates), but differs markedly by this parameter from the rat myocardium (vertebrates). It has also been revealed that AC in the worm muscle is regulated by peptide hormones, relaxin and somatostatin, whose action is comparable with that in the mollusc muscle, but much weaker that the action of these hormones on the rat myocardium AC activity. Use of Cterminal peptides of α-subunits of G-proteins of the stimulatory (385–394 Gαs) and inhibitory (346–355 Gαi2) types that disrupt selectively the hormonal signal transduction realized via Gsand Giproteins, respectively, allowed establishing that the AC-stimulating effects of relaxin, octopamine, tyramine, and dopamine in the worm muscle are realized via the receptors coupled functionally with Gs-protein; the AC-inhibiting effect of somatostatin is realized via the receptor coupled with Gi-protein, whereas serotonin and tryptamine activate both types of G-proteins. |

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.
