Experimental iron deficiency in Syrian hamsters (Mesocricetus auratus)

An animal model was developed in which the effect of iron deficiency on the oral mucosa could be studied. Iron deficiency was induced by feeding hamsters a low-iron powdered diet together with withdrawal of 0.5 ml of blood weekly, for a period of 9 weeks. At the end of this period the mean haematological values for control animals were, Hb 15.9 g/dl, plasma iron 40.3 mumol/l, TIBC 90.5 mumol/l and transferrin saturation 44.5%, compared with 7.4, 7.2, 111.4 and 6.5 respectively for experimental animals. These results were reproducible in successive groups of animals and indicate that this is a useful model for the study of iron deficiency anaemia.
