Malignant GLHW was higher than in benign one (it was malignant if the GLHW was 50% or more in ovary, uterine cervix, and endometrium). The GLHW of placental fibrin deposit was higher than normal placenta. It was reduced by heparin and normal neonate was obtained. Fetal brain echo density, immature fetal lung, and meconium-stained amniotic fluid were diagnosed by GLHW, and normal adult liver …
