Background The aim of this study was to evaluate the functional capacity of the liver based on the activity of specific enzymes and bilirubin in serum and also to investigate the influence of mechanical and toxic effects of Fasciola hepatica on the structures of the blood vessels and biliary tract in the sheep liver. Methods Blood samples and liver of 63 indigenous sheep of Pramenka breed, slaughtered in the period from March to December 2009 were used. Based on parasitological findings in the liver, all animals were divided into two groups: control (n = 34) and infected group (n = 29). For investigation and description of pathological changes in sheep liver, naturally infected with F. hepatica, corrosion cast technique was used. Results Biochemical analysis of tested parameters showed a significant elevation (P≤0.05) of serum gamma-glutamyl transferase (GGT), total bilirubin (TBIL) and direct bilirubin (DBIL) in infected sheep group comparing with the control group. No significant differences were observed for activity of aspartate aminotranferase (AST) between groups. Vascular and biliary systems of the liver were found to be affected. Conclusion Results of biochemical analysis are consistent with pathological findings and measuring of tested parameters could be used in early diagnosis of sheep fasciolosis and to test the effectiveness of anthelmintic therapy. Corrosion cast technique is very useful for investigation of pathological changes and neoangiogenesis of vascular and biliary system in sheep liver, caused by mechanical and toxic effects of F. hepatica.

The present paper analyzes the status of women politicians and the amount of their representation in the discourse of four daily newspapers (Dnevni Avaz, Oslobođenje, Glas Srpske and Press) during local pre-electoral campain in B&H in 2012. Content analysis which was conducted in this research shows that female politicians are under-represented and invisible. This conclusion was drawn based on the frequency of their newspaper representation in aggregate and in specific journalists' forms of reporting. Through techniques of discursive negotiations of gender in and through media, women's "simbolic annihiliation" is thus brought about, having at the same time ontological consequences with respect to the status of women in matters regarding res publica. At the same time, by using the semiotics of Judith Butler, it is highlighted that this imposition of women's subordination, which is in its very essence patriarchal, makes room for disidentificational resistance through gender-sensitive performative acts and political engagements.
