[Morphology and histology of the placenta from parturients of various nationalities in the Tibet plateau].
The morphology and histology of placentae from Tibet have been studied and reported in this article. The subjects studied were 51 Tibetan women and 19 Han women who were healthy and pregnant 38 to 42 weeks. The Han women had migrated to Tibet plateau from the plains. It showed that Tibetan women had newborns of significantly higher birth weight and lighter placentae and also a higher positive rate than Han woman in syncytial nodes, vascular syncytial membranes, vascular proliferation and cellulose-like necroses. There was a very significant difference between women living at high-altitude and women living at sea-level in most parameters.
