[The pathomorphology of the kidneys in the fetuses of mothers suffering from late gestosis, type-1 diabetes mellitus and chronic glomerulonephritis].

Fetal kidneys from mothers with late gestosis, diabetes mellitus-1 and chronic glomerulonephritis were studied. There were features of the maturation slowing down and some disturbances in differentiation of rental tissue were revealed. Local degenerative, membranous, proliferative and fibroplastic changes with formation of immune complexes including IgM and C3-complement in late gestosis, IgA, G, C3-complement fractions IgG, M, C3-complement fraction and traces of membranous and proliferative alteration were observed in chronic glomerulonephritis, they were less frequent in diabetes mellitus in mothers, and not so often in late gestosis. Activation of collagen production of types I, III, IV and V was most commonly observed in diabetes mellitus, in chronic glomerulonephritis and late gestosis, it being more rare.
