| Abstract | 1. The effects of temporary short-term paralysis on changes of motor unit size and amount of sprouting after partial denervation of the rat soleus were studied. 2. Two to ten months after section of the L5 ventral ramus combined with subsequent treatment with alpha-bungarotoxin (BTX) the tension developed by the operated muscle was 39 +/- 8% (S.E.M., n = 8) of control unoperated soleus muscles. This is much less than the tension produced by partially denervated, NaCl-treated or untreated muscles which was 66 +/- 9% (S.E.M., n = 5) and 66 +/- 12% (S.E.M., n = 5) respectively. The smaller tension developed by the BTX-treated muscles was due to the relatively small size of their motor units. 3. The mean increase of tension output of individual motor units after partial denervation and treatment with NaCl when compared with controls was 194 +/- 15% (S.E.M., n = 4) while in the paralysed muscle this value was only 118 +/- 15% (S.E.M., n = 8). This reduced expansion of motor unit size in the BTX-treated soleus was not caused by a decrease of the size of the muscle fibres. Thus a brief temporary paralysis prevents the expansion of motor unit territory that normally occurs in partially denervated muscles. 4. Examination of the innervation pattern and incidence of sprouting revealed that in partially denervated NaCl-treated muscles 24 +/- 4% (S.E.M., n = 4) of endplates was contacted by either terminal or collateral sprouts, whereas in the BTX-treated muscles only 5 +/- 2% (S.E.M., n = 3) of endplates had been contacted by sprouts. Treatment with BTX alone, without partial denervation, did not affect the tension output of the muscles, but caused 8 +/- 5% (S.E.M., n = 3) of the endplates to become innervated by collateral sprouts, as compared to only 3 +/- 2% (S.E.M., n = 3) in controls. |

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.
