| Abstract | Histological and metallothionein (MT) analyses of liver and kidney and measurements of serum electrolytes and hematocrit from lake whitefish (Coregonus clupeaformis), 3.5 years of age, were conducted over a 90-day period that included maximal gonadal maturation in females. Condition factors were higher in females at day 1 and when all data were combined over the 90-day sampling period. Significant differences between females and males of 1.8-fold in hepatic MT concentrations were observed at day 20 when ovaries appeared to be in the most advanced state of maturation, although this parameter was not quantified. Hematocrits were slightly but significantly lower at day 90. No sex differences were observed in the quantitative assessments of epithelium cell height, lumen diameter (LD), tubule diameter (TD), and ratio of LD:TD in the second segment of the proximal tubule (P2); and of hepatocyte area, hepatocyte nuclear diameters, and nucleus area:cytoplasmic area (N:C) ratio. Positive correlations were observed between N:C ratios and fish weight, fork length, and liver weight. No significant correlations between these histological morphometrics and MT concentrations were observed in liver or kidney. The results of this study provide baseline information for investigations designed to determine sublethal effects of metals in lake whitefish. |

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.
