| Abstract | Cypermethrin, a type II synthetic pyrethroid insecticide, @ 0.5mg/kg/day for 14 consecutive weeks produced mild signs of toxicity in buffalo calves. Significant changes were observed in various antioxidant parameters in blood. There was a marked increase in the extent of lipid peroxidation (33.9%) and enzymic activity of glutathione peroxidase (6.7%), superoxide dismutase (35.0%), catalase (43.7%), glutathione-S-transferase (64.4%), glutathione reductase (36.7%) and glucose-6-phosphate dehydrogenase (32.1%). A significant decrease in blood glutathione (16.7%), total antioxidant activity (45.4%) and vitamin E (40.8%) was observed and no significant effect was found on blood selenium levels. However, the extent of lipid peroxidation (42%) and the depletion of glutathione (28.8%) was greater after dermal sub-acute toxicity of cypermethrin (0.25%) for 14 consecutive days. Similarly, it was observed that the incline in the enzymic activity of glutathione peroxidase (29.7%), superoxide dismutase (38.3%) and glutathione reductase (38.3%) was higher in dermally cypermethrin exposed animals. Thus, the present investigation contemplates that oxidative stress is the important mechanisms involved in cypermethrin-induced toxicity and the oxidative insult produced by dermal route is more severe as compared to oral intoxication. |

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.
