Abstract
The erythroid lineage was studied in the flounder-gloss (Platichthys flesus Linnaeus, 1758) during the annual cycle. The erythrocyte count in the blood was determined along with the contents of immature erythroid forms (basophilic and polychromatophilic normoblasts) in the head kidney (pronephros) and the blood. Cell proliferative activity was inferred from the [3H]thymidine inclusion in circulating immature erythrocytes. Irregularity was observed in erythropoiesis occurring in flounder-gloss hematopoietic tissue. Intense production of erythroid mass was mainly associated with a post-spawning period. This was evident from an increase in the contents of immature erythroid forms in the pronephros and circulating blood and an increase in their proliferative activity. The changes were associated with peculiarities of the erythroid system organization, which precludes regular production of erythropoietin in the kidney in teleost fish.
期刊介绍:
Doklady Biological Sciences is a journal that publishes new research in biological sciences of great significance. Initially the journal was a forum of the Russian Academy of Science and published only best contributions from Russia in the form of short articles. Now the journal welcomes submissions from any country in the English or Russian language. Every manuscript must be recommended by Russian or foreign members of the Russian Academy of Sciences.
