The impact of background γ-radiation on erythrocyte nuclear pathology, the serotonergic system, and cytochrome P-450 in hens (GALLUS GALLUS DOMESTICUS) from Azerbaijan.

High levels of background γ-radiation exist in the suburbs of Baku, Azerbaijan. We examined the impact of radiation on erythrocyte nuclear pathologies, levels of cytochrome P-450, and serotonin-modulating anticonsolidation protein (SMAP) in the tissues of the hens from three settlements with different levels of background radiation. Higher levels of radiation resulted in increased nuclear pathologies, upregulation of tissue SMAP levels, and downregulation of cytochrome P-450.
