Kallistatin is a serine proteinase inhibitor which binds to tissue kallikrein and inhibits its activity, The aim of this study is to evaluate if kallistatin has a direct effect on the vasculature and on blood pressure homeostasis. We found that an…

Contractions of rat thoracic aorta to vasopressin WP) are threefold higher in females (F) than in males (M), primarily because nitric oxide (NO) attenuation of contraction is greater in M. To determine the role of the androgen receptor (AR) in this…

Endothelial nitric oxide synthase (eNOS) is critical in the regulation of vascular function, and can generate both nitric oxide (NO) and superoxide (O2•−), which are key mediators of cellular signalling. In the presence of Ca2+/calmodulin, eNOS…

Several recent studies have provided evidence that gonadal steroid hormones can exert acute (nongenomic) effects on both neural and vascular tissues. This study examines the acute effects of testosterone (T) on vascular reactivity of the rat thoracic…

To determine the correlation between ultrastructural and physiological changes in blood-gas barrier function in lungs transiently exposed to very high vascular pressures, we increased capillary transmural pressure (Ptm) of 6 canine isolated perfused…

In rat thoracic aorta, contractile responses to arginine vasopressin (AVP) are twofold higher in females than in males. To determine the role of the endothelium in this phenomenon, the effects of endothelium removal and inhibition of nitric oxide…

We determined whether the solvent drag reflection coefficient (sigma f) for total proteins of a canine perfused left lower lung lobe (LLL) preparation decreases at elevated venous pressures (Pv). We found that sigma f (estimated using the…
