1. Conctraction-mediating receptors in human peripheral vessels with special reference to veins and lymphatics
Sammanfattning : By means of a myograph, postjunctional alpha-adrenoceptors were characterized in human superficial epigastric arteries and veins obtained from health subjects. The rank order of potency of subtype selective agonists could not be used for receptor characterization in these vessels, whereas antagonists gave distinct results. LÄS MER
2. Human Endometrial Angiogenesis : An Immunohistochemical Study of the Endometrial Expression of Angiogenic Growth Factors and Their Corresponding Receptors
Sammanfattning : The human endometrium undergoes dramatic changes in morphology and function during the menstrual cycle. Recurrent angiogenesis (the formation of new blood vessels) is of utmost importance for oxygen supply and nourishment of the rapidly growing endometrial tissue. LÄS MER
3. Endothelin and angiotensin II receptors in human coronary arteries and bypass grafts - Alterations in cardiovascular disease
Sammanfattning : Angiotensin II (Ang II) and endothelin-1 (ET-1) induce strong vasoconstriction via activation of receptors on vascular smooth muscle cells. In this thesis, the contractile Ang II and endothelin receptors were examined in endothelium-denuded human coronary arteries and in bypass grafts (the left internal mammary artery and the saphenous vein), with focus on receptor alterations in cardiovascular disease.

Sammanfattning : Background and general summary: Ovulation is the cascade of events ending with follicular rupture and oocyte extrusion. This ovulatory process is triggered by the LH surge, which induces biochemical and biophysical alterations within the preovulatory follicle. LÄS MER
5. Direct and endothelium-linked serotonergic control of vascular tone in human uterine and umbilical arteries
Sammanfattning : The serotonergic vascular control was investigated by in vitro pharmacology in the human uterine and umbilical arteries. The localisation of immunoreactive (IR) neuropeptide Y (NPY) and the influence of NPY on the adrenergic vascular effects in the human uterine artery were also studied. LÄS MER
