Directly under the ependyma, and between the ependymal cells, there are basement membranes which form labyrinths connecting with the perivascular basement membranes of the subependymal vessels. The basement membranes exhibit differences in form, position, and distribution, and they can be distended by fluid absorption into large lacunae. The membranes can(More)
71 women were examined daily for the presence of headache in their first post partum week. Post natal headache (PNH) occurred in 27, (39%) of the women and was most frequent on days 4-6 post partum. PNH was significantly associated with a previous or family history of migraine and pre-menstrual migraine. Although 83% of those with PNH had a migraine(More)
Tissue homeostasis is fundamentally influenced by the functional integrity and state of endothelial cells. Survival and death of endothelial cells are encountered in cardiovascular disease and may, moreover, affect and determine the development of atherosclerosis and restenosis following intracoronary therapeutical interventions. Apoptosis was studied in(More)
The rhombencephalic recess, an ependymal organ, has been studied for the first time by light- and electron microscopy. It is situated mediosagitally on the floor of the rhomboid fossa at the level of the colliculus facialis. The recess and the superimposed tissue are built up by tanycytes, their apices being connected by tight junctions. HRP, injected into(More)
The synthesis of vasopressin in hydrocephalic rats has been studied by immunohistochemical, karyometrical and densitometrical methods. Signs of a decreased synthesis of vasopressin in the hypothalamo-neurohypophyseal system were found. No signs of a diabetes insipidus were observed.
