| Abstract | OBJECTIVES: The present study assessed the effect of adolescent alcohol exposure on the later aversive and locomotor-activating effects of cocaine. METHODS: Male rats were exposed to alcohol or vehicle for 10days [postnatal day (PND) 30-39; 2g/kg IP]. Taste aversion conditioning began on PND 65. During aversion conditioning, subjects were presented with saccharin followed by cocaine (32mg/kg; 15, 180 or 300min post saccharin) or saline. Following each injection, animals were placed in locomotor chambers for 1h. To determine if any effects seen were specific to the adolescent developmental period, the procedure was replicated in adult animals. RESULTS: Animals exposed to vehicle during adolescence showed significant aversions at all time delays. Animals exposed to ethanol during adolescence showed a decrease in consumption only at the 15 and 180min delays. Groups exposed to alcohol during adolescence showed a decrease in gross, and an increase in fine, motor activity in response to cocaine. Animals exposed to alcohol during adulthood also showed attenuated taste aversions. CONCLUSIONS: Exposure to ethanol during adolescence attenuated the aversive effects of cocaine and altered its locomotor-activating effects. Although this effect is not specific to adolescence, this is the time when alcohol use is typically initiated so that such exposure may enhance later abuse liability of cocaine. |

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.
