[Morphometry of the juxtaglomerular apparatus of allo-transplanted human kidneys].
Juxtaglomerular appartus of 17 allotransplanted human kidneys was studied by the karyometric method at various periods of existence in the recipient's organism. Kidneys of persons who died of craniocerebral trauma or acute cardiac incompetence served as control. At the early periods (up to 2 months) there was revealed an authentic increase in the nuclear volume of the epitheloid-modified cells of the afferent arteriole and of the Goormaghtigh cells. There was also a tendency to increase in the volume of the macula densa cells. At the late periods the juxtamolecular apparatus persisted in the allotransplanted kidneys with a but little injured parenchyma. Reduction of the juxtaglomerular appartus occurred in case of marked sclerosis and atrophy of the transplant parenchyma.
