Role of some biogenic amines in the pathomechanism of glomerulonephritis. I. Histological examinations of kidneys in acute and chronic serum sickness in rabbits.

Investigations were carried out on the role of biogenic amines in the development of glomerulonephritis in rabbits using the experimental model of acute and chronic serum sickness. The animals immunized with foreign-species albumin received additionally 5HT and some of them were given reserpine or PCPA for reducing the level of biogenic amines. The results of histological examinations demonstrated a clear cut inhibitory effect of PCPA and reserpine on the development of inflammatory changes in the glomeruli, and their intensification with simultaneous 5HT administration. The obtained results seem to suggest a significant role of biogenic amines in the pathogenesis of inflammatory lesions developing in renal glomeruli in acute or chronic serum sickness in rabbits.
