| Popis: | The metabolic activity of amniochorion contributes to the control of activation of labor-type uterine contractions. The study presents an experimental model of transport of calcium ions across the human amniochorion sampled directly after cesarean section in patients delivering both at term and prematurely. Transmembrane transport of calcium ions was lower in preterm vs. term tissue samples. The differences in permeability were most pronounced in the first 60 min of experiments. The results of the study provide evidence for the existence of an active mechanism of calcium transport which can contribute to regulating the contractility of the uterus. |
