[Comparative characteristics of villous chorionic polysaccharides during the first 3 months of human uterine and tubal pregnancy].
Qualitative composition of polysaccharides has been studied in 100 chorions of human fetuses, 3.5--12 weeks of embryonic development, 40 of them have been obtained from tubal pregnansies. It has been stated that in villous stroma of the tubal pregnancy at the 4--5th week of gestation, sulphate polysaccharides appear that demonstrates an earlier maturation of villi at this type of pregnancy. It is possible that in the formation of intracellular substance of the villous stroma together with fibroblasts Kastschenko -- Hoffbauer's cells also participate. A characteristic feature for the tubal pregnancy is the appearance of distrophically changed villi beginning from the 4th week of gestation. In plasmodiotrophoblast of such villi the amount of Hale-positive and PAS-positive substances is sharply decreasing, and neutral polysaccharides, chondroitin-4-sulfate, chondroitin-6-sulfate and dermatan-sulfate (small amount) are intensively accumulating in the stroma.
