Dynamics of cytochemical parameters of pseudoeosinophils in the blood of guineafow

Resumo

The cytochemical organization of neutrophils and pseudoeosinophils in different classes of vertebrates is poorly studied. The purpose of this study is to determine the cytochemical status of pseudoeosinophils in the blood of guineafowl. We analyzed the blood of Volga white guineafowl breed, colored blue and gray-speckled guineafowl populations (174, 186, and 208 days) and one-day-old nestlings of these populations. It was found that the changes in cytochemical blood cell parameters during the period of development (days 174–208) were multidirectional: the activity of acid phosphatase and glycogen increased, while the activity of myeloperoxidase and alkaline phosphatase decreased. The activity rates of myeloperoxidase and lysosomal-cationic proteins during this period were stable.
