Constriction of Human Umbilical Arteries
Experiments on perfused segments or isolated rings of human umbilical artery showed that the magnitude of their contraction in response to bradykinin, epinephrine, or serotonin depended on the P02 of the perfusing or bathing solution. Constriction to bradykinin varied directly with the O2 tension and was greatest when the Po2 was approximately that of umbilical arterial blood during the transit...
متن کاملMechanisms of contraction induced by human leukocytes in normal and atherosclerotic arteries.
Activation of leukocytes results in the release of a variety of vasoactive substances that may modulate vascular tone. We studied the effect of human polymorphonuclear (PMN) and mononuclear (MONO) leukocytes on quiescent femoral arteries in vitro. Arteries were obtained from normal and atherosclerotic cynomolgus monkeys. In normal arteries, stimulation of PMNs (3 and 5 x 10(6) cells/ml) with ei...
متن کاملEndothelial modulation of the ouabain-induced contraction in human placental vessels.
Ouabain (1 x 10(-7)-3 x 10(-5) M) elicited concentration-dependent vasoconstriction in human placental arteries and veins. These responses, but not those produced by 10(-6) M 5-hydroxytryptamine, were increased after the removal of vascular endothelium. In placental arteries, the respective blockade of cyclooxygenase or lipoxygenase with indomethacin of 5,8,11,15-eicosatetraynoic acid as well a...
متن کاملProteoglycans of human umbilical cord arteries.
Proteoglycans (PGs) were dissociatively extracted from human umbilical cord arteries (UCAs) with 4 M guanidine hydrochloride containing Triton X-100 and protease inhibitors, purified by Q-Sepharose anion exchange chromatography and lyophilized. They were analysed by gel filtration, SDS/PAGE and agarose gel electrophoresis before and after treatment with chondroitinase ABC. It was found that the...
متن کاملLate Antiquity and Early Islam
In this paper, an investigation on the relation between state-building and Near Eastern religion is attempted. Analyzing the city-state of Ḥaṭrā (Iraq, close to Kirkuk), it is demonstrated that pre-Islamic state craft in the region was dependent on the initiative of the Parthian monarchy in Iran. The kings of the Arsacid dynasty attempted to bestow the local Arabic tribes in the Jazira with a c...
