Isolated dog internal thoracic arteries (ITA) responded to norepinephrine and phenylephrine with concentration-related contractions, which were suppressed by prazosin, but not by yohimbine. Clonidine did not contract ITA. In coronary arterial strips, norepinephrine produced a relaxation. Isoproterenol relaxed coronary arterial strips contracted with serotonin but did not alter the tone of ITA. ...
conclusions diclofenac-loaded nanoparticles based on properties of chitosan gelation could delay the release of drugs in the stomach and be further evaluated for the enteric delivery of diclofenac. objectives the aim of this study was to prepare and evaluate diclofenac-loaded chitosan nanoparticles based on the ionotropic gelation method. materials and methods chitosan (cs) nanoparticles contai...
Inhaled nitric oxide (INO) is a selective pulmonary vasodilator that has the ability to produce vasodilation in the pulmonary vascular bed without causing it in the systemic circulation. This property of INO has made it a useful therapy in the management of both adult and paediatric patients with a variety of conditions associated with pulmonary hypertension (PH), with or without hypoxia. Toxic...
Pulmonary arterial hypertension (PAH) is characterized by vasoconstriction and smooth muscle cell proliferation of the pulmonary arterioles, as well as in situ thrombosis of the small pulmonary arteries. Prostacyclin is involved in PAH vascular remodeling. It is unclear if decreased prostacyclin in the lungs is a cause or a consequence of PAH, but the relative lack of prostacyclin and its posit...
We read with interest the article by HUMBERT et al. [1] on the difference in prognosis in prevalent versus incident cohorts of patients with pulmonary arterial hypertension (PAH). The study highlights a survival bias in the prevalent cohort due to under-representation of more severely ill patients that might have died before inclusion in the registry. HUMBERT et al. [1] subsequently found a 1-y...
