Abstract

Th e morphofunctional state of the mesonephros of the sterlet (Acipenser ruthenus Linnaeus, 1758) from the lower reach of the Dnieper river has been studied through the light optical method. The adaptive changes in the structure-functional elements of the mesonephros nephrons have been observed. Among the most perceivable shift s are focal hemorrhage of the reticulo-myeloid tissue, swelling of the epithelium and infl ammatory processes. The abnormalities reported are a response to the negative impact of the wastewater constituents.
