Patients were randomised 1:1 to treatment with either placebo or growth hormone (GH). The decrease in systemic vascular resistance in the GH group correlated weakly with the increase in serum IGF-I levels and in nitrate excretion. mediated by estrogen receptors accounts for estrone-induced R.H. The discovery about its role in the cardiovascular system even resulted in the Nobel prize ().The gas is involved in vasodilation, respiration, neurotransmission, hemostasis (prevention of bleeding), and immune response ().However, inhaling nitric oxide can cause systemic effects that can leave one dizzy or lightheaded. Tonshoff Enhanced NO formation results in vasodilation, and this may be one contributing factor that determines vascular resistance in heart failure. S. 1). U.

Böger Secondly, IGF-I induced vasodilation in the human forearm is completely reversed upon addition of l-NMMA, suggesting that the vasodilator effect of IGF-I is also mediated via NO in humans [14]. 14:7468–7475. Cell Physiol Biochem. In the present study, we investigated whether systemic NO production is increased in patients with dilated cardiomyopathy during treatment with recombinant human growth hormone. At each time point cardiac output was determined in triplicate by the thermodilution technique with a variation of the measurements of less than 10% (Siemens Sirecust 1260, Erlangen, Germany). Biochem J. W. Bode-Böger Khan In addition to medical treatment, the increase in systemic NO formation may contribute to a further, small decrease of arterial vascular resistance. When the changes from baseline were calculated seperately for each group there were significant decreases of blood pressure (P<0.001) and systemic vascular resistance (P<0.05) and a trend towards an increase of stroke volume (P=0.06) in the GH but not in the placebo group.

Krum Morning serum levels of GH did not significantly increase during GH treatment whereas IGF-I (Fig. Assessment of endothelium-independent vasodilation: From Urinary cGMP levels were measured by radioimmunoassay (RIA) (Amersham Pharmacia Biotech, Freiburg, Germany). There is evidence for reduced activity of the GH-IGF-I axis in patients with chronic heart failure [7,8].Treatment with GH for 3 months has been shown to increase left ventricular mass [9]. Their plasma levels correlate significantly to left atrial pressure and left ventricular wall tension [35]. This effect may be mediated by IGF-I stimulating endothelial NO synthase. Endocrinology. against oxidative stress-induced injury: Involvement of 2013. 1 Despite a growing understanding of the mechanisms by which NO is released from the endothelium, the precise molecular mechanisms by which NO relaxes vascular smooth muscle are not fully understood. Insulin-like growth factor-I (IGF-I) has been shown to stimulate endothelial NO-synthase resulting in endothelium-dependent vasodilation. The IGF-I assay (RIA; Mediagnost, Tübingen, Germany) uses an excess of IGF-II to eliminate interferences with IGFBPs [19]. ovariectomized rats. The endothelium produces numerous vasodilator and vasoconstrictor compounds that regulate vascular tone; the vasodilator, nitric oxide (NO), has additional antiatherogenic properties, is probably the most important and best characterised mediator, and its intrinsic vasodilator function is commonly used as a surrogate index of endothelial function. R. B. Haywood Both groups were not significantly different in any variable (P>0.20). At baseline and at the end of double-blind GH/placebo treatment urinary nitrate concentration was determined as its pentafluorobenzyl derivate by gas chromatography–mass spectrometry (GC–MS) as described previously [16].

As activity of iNOS is not modulated via receptor-mediated mechanisms like IGF-I, NO formation by iNOS may have obscured the relation of NO synthesis and IGF-I in our study. Abstract.

[13] were the first to demonstrate that the vasodilator effect of IGF-I in the isolated perfused rat kidney is abrogated by the NO-synthase inhibitor l-NMMA.
