11. Endothelial dysfunction in the pulmanory circulation after cardiopulmonary bybass : with special reference to the reactivity to acetylcholine
Abstract : The endothelium is important as a physical barrier between the bloodstream and the body tissues. It also plays an important role in the control of vasomotor tone, coagulation, and for the interaction between the vessel wall, leukocytes and platelets. One of the most important regulators released from the endothelium is nitric oxide (NO). READ MORE

12. Effects of nitric oxide on hemostasis with special attention to platelet function
Abstract : Endogenous endothelium-derived NO provides a continuous vasodilating effect, but may also in humans have an antithrombotic effect, which is exerted by inhibition of platelet function and by vasodilatation. Inhalation of NO selectively relaxes the pulmonary vascular bed, without causing systemic hypotension. READ MORE

13. Vardenafil and methylarginines in pulmonary hypertension
Abstract : Background: Pulmonary hypertension (PH) is a rare condition characterized by endothelial dysfunction and vascular remodelling, leading to increased pulmonary vascular resistance (PVR) and right ventricular heart failure. Endothelial dysfunction is associated with an imbalance between vasoconstrictor compounds, such as endothelin and thromboxane A2, and vasodilator compounds, such as prostacyclin and nitric oxide (NO).

14. The influence of nitric oxide and cholecystokinin on tissue homeostasis in exocrine pancreas : an experimental study in rats
Abstract : Growth of the pancreas is stimulated by cholecystokinin (CCK) in rats. Nitric oxide (NO), which is synthesized from the amino acid L-arginine by NO-synthases (NOS), interferes with CCK in modulating the pancreatic secretion. READ MORE

15. Studies on the mechanism for natural killer cell cytotoxicity and its regulation
Abstract : Since the proposed perforin-granzymes exocytosis can not sufficiently account for NK cell mediated cytolysis, the existence of a new and yet unknown mechanism for induction of the damage to targets by NK cells has been suggested. Our data illustrates that NK cell oncolytic activity has a requirement for L-arginine. READ MORE
