[Reactive properties of the glomerular mesangial cells during extreme loading of the kidney].

The authors consider the ultrastructure of mesangial cells of the renal glomerular corpuscle in health and simulation in 3 series of experiments on white rats of acute circulatory ischemia, vasorenal hypertension and vicarious hypertrophy of the kidneys. Special attention is paid to the processes of these cells which are represented by three types. In high hemodynamic load of the kidney unusual mesangiocapillary prolapses (type 3 processes) experience marked hypertrophy. Some aspects of their functional importance are discussed.
