The state of the red bone marrow in rats depending on age in case of poisoning with lead acetate and potassium dichromate

Introduction: The current ecological situation is described by a rapid increase in air pollution through various chemical emissions. Aim: study aims to define how the level of lead and chromium compounds affects parameters red bone marrow blood animals these processes depend on their age. Material methods: To toxic intraday effect heavy metals, metal probe was used for combined priming rats with acetate potassium dichromate. indicators were analyzed use cytogram, indices ratio between young mature forms calculated. obtained factual material subjected computer processing calculation Student’s criterion confidence intervals. Results discussion: It established that there an accumulation polychromatophilic cells large amount hemoglobin, which leads violation maturation – that, subsequent stage division passes very quickly, when, upon transforming into orthochromatic normoblasts, they pass after 15–20 h, forming variant terminal division. In old animals, decrease total cellularity severe anemia. Conclusions: After experiments profound analysis, author defined difference effects animals.
