| 释义 | villous adjective anatomy specializeduk /ˈvɪl.əs/ us /ˈvɪl.əs/ relating to or in the shape of villi(= very small, finger-like parts on the inside of the small intestine): The condition is characterized by villous atrophy occurring in the proximal small bowel. Villous adenomas are most prevalent in men older than 55. An adenoma can have both tubular and villous features. Malabsorption may be secondary to compromised villous surface area, such as in coeliac disease. The villous atrophy seen on biopsy may also be due to unrelated causes.

Our understanding of the mechanisms involved in regulating the turnover of villous trophoblast throughout pregnancy is in its infancy. Xanthine oxidase activity in preeclamptic women is higher in invasive but not villous trophoblast. This pathological condition l e a d s to mucosal damage including villous atrophy and crypt hypertrophy. From this layer, trophoblast cells differentiate along two main pathways + villous and extravillous. In hookworm infections villous atrophy may be partially explained also by the grazing activities of the adult worms. It is due either to an area devoid of a villous tree, or a septal cyst. Within the human placenta the villous trophoblast represents the epithelial covering of the chorionic villi. Villous atrophy is also found in several other intestinal disorders. The active inflammation induced by this mechanism leads to loss of villous height and increased crypt depth. The relationship between antiendomysium antibodies and villous atrophy in coeliac disease using both monkey and human substrate. Proliferation, differentiation and apoptosis in villous trophoblast at 13+41 weeks of gestation (including observations on annulate lamellae and nuclear pore complexes). Intrauterine growth restriction with absent end-diastolic flow velocity in the umbilical artery is associated with maldevelopment of the placental terminal villous tree. Chorionic villous biopsy can be offered for prenatal diagnosis of aneuploidy from 11 weeks gestation provided the two placental discs have not fused. He showed the histopathologic picture to be a continuum from normal villous architecture with intraepithelial lymphocytosis (stage 1), through crypt hyperplasia (stage 2) to total villous atrophy (stage 3).
