Peculiar Features of Hematopoiesis in the Liver of Mature and Immature Green Frogs (Pelophylax esculentus complex)

Akulenko, N. M.



The article describes characteristic features of the hematopoiesis in mature and immature green frogs (Pelophylax esculentus complex). Quantitative differences in liver myelograms were insignificant. However, in a sample of mature animals numerous signifi cant correlations between the number of pigment inclusions in the liver and indicators of erythropoiesis and myelopoiesis were observed. Those correlations were absent in the immature frogs. We concluded that after the frogs’ breeding a lack of plastic resources, in particular, hemosiderin remains up to the hibernation.
