| Abstract | Diaveridine (DVD), belonging to the class of compounds called diaminopyrimidines, has been widely used as a bacteriostatic agent. To evaluate the reproductive toxicity and teratogenic potential of DVD, different concentrations of DVD were administered to Wistar rats by feeding diets containing 0, 23, 230, 1150 and 2000 mg kg−1 of DVD. Each group consisting of 18 males and 25 females (F0) was treated with different concentrations of DVD through a 13-week period prior to mating, during mating, gestation, parturition and lactation. At weaning, 20 males and 25 females of F1 generation weanlings per group were selected randomly as parents for the F2 generation. The selected F1 weanlings were exposed to the same diet and treatment as their parents. In the F0 and F1 generation of the 1150 and 2000 mg kg−1 diet groups, the body weight, feed efficiency, weight gain of pregnant rats, litter and average number of live fetuses and fetus body weight significantly decreased. In the highest dose group, uterine wall contraction, narrow uterine cavity and uterine tumor were observed. Combined with the 2nd generation reproduction test to investigate the teratogenic toxicity of DVD in Wistar rats, the pregnant rats were subjected to caesarean section on the 20th gestational day for examination. For the 1150 and 2000 mg kg−1 groups, the litter weights, body weights, body length, tail length of fetus and number of viable fetuses significantly decreased. There were no obvious external, skeletal and visceral effects in all the groups. The no-observed-adverse-effect level for reproduction/development toxicity of DVD was 23 mg kg−1 diet (about 2.3–2.8 mg per kg b.w. per day). |

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.
