Transferrin, haematological indices and liver glycogen in field mice collected from a coal mining area and a control site in Poland.
A polymorphism for serum transferrin in field mice from polluted and control sites was compared with body-morphological and haematological parameters, and with liver glycogen concentration. The distribution of genotypes in the polluted area was not panmictic, due to higher frequencies of the rare allele Trf(c) occurring mainly in males. In the polluted area, transferrin-c was accompanied by slowly migrating, Fe-binding protein fractions. Since the Trf(c)/Trf(c) homozygote possessed higher red blood cell parameters, it is suggested that these extra proteins have an Fe-transport function. The morpho-physiology of heterozygotes from the polluted area did not differ significantly from those from the control site. The animals from the polluted area possessed a high concentration of liver glycogen, indicative of poor environmental conditions. Also, a generally lower level of red blood cell parameters suggests that non-oxygenic processes dominate over oxygenic ones in the polluted area.
