Distinctive features of hepatocytes in five small mammal species (insectivores and rodents): taxonomic versus ecological specificity

Análise histomorfométrica do fígado e pâncreas de três espécies de aves de rapina: Caracara plancus, Rupornis magnirostris e Coragyps atratus / Histomorphometric analysis of the liver and pancreas of three species of birds of prey: Caracara plancus, Rupornis magnirostris and Coragyps atratus

“…As previously mentioned, a higher occurrence of binucleated cells may be related to liver regeneration processes (Veiga 1982;Davydova 2017). Provided that, it is expected that species exposed to environmental conditions and diets that contribute to contamination in the liver have a higher index of binucleated cells per tissue area.…”

“…Related to the use of histomorphometry for this study, Davydova (2017) cite that its use in quantitative analysis is more objective than qualitative analysis, however this type of quantitative analysis is little used in scientific studies. Considering that all individuals of C. atratus studied are females, the fact that there was intraspecific variation in the concentration of binucleated cells suggests that the animals probably presented different responses of the organism to environmental conditions.…”

“…According to Popescu et al (2012) and Davydova (2017), the cellular metabolic rate and responses to tissue repair processes can be estimated by analysing the relationship between the size of the nucleus and the cytoplasm. Also, Popescu et al (2012) observed that after a hepatectomy procedure in rats, there was an increase in liver nuclei.…”
