OBJECTIVE
To test the possible role of endothelial cells in mediating fade of norepinephrine-induced constriction and the effect of heartworm infection on these responses.
METHODS
Rings of pulmonary vein from control and heartworm-infected dogs were constricted with norepinephrine (10(-5.5)M) and
OBJECTIVE
To investigate the contractility of pulmonary arterial smooth muscle and the relation between pulmonary hypertension and endothelium-derived relaxing factor in canine heartworm disease.
METHODS
18 noninfected control and 9 heartworm-infected dogs.
METHODS
Mean pulmonary arterial blood
Canine cardiopulmonary dirofilariosis caused by Dirofilaria immitis habitually develops as a chronic disease affecting pulmonary arteries, lung parenchyma and heart. Other organs like kidneys can also be involved. Renal pathology is a consequence of glomerulonephritis whose main sign is proteinuria.
