The retinal vessel filling time of 10 patients with early nonproliferative diabetic retinography was measured by fluorescein angiography. Initially, the reproducibility of the authors' standardized fluorescein angiography was assessed by control angiograms on two different dates in each patient. Thereafter, prolonged use (six months) of isoxsuprine sustained release (80 mg/day) led to a nearly 50% reduction of the arterial filling time and a nearly 25% reduction of the arteriovenous filling time, whereas no changes were seen in control patients. This effect of isoxsuprine might be explained by an increase of red cell deformability and, concomitantly, a decrease of platelet adherence in the microcirculation of patients with diabetic mellitus.

UI MeSH Term Description Entries
D007556 Isoxsuprine A beta-adrenergic agonist that causes direct relaxation of uterine and vascular smooth muscle. Its vasodilating actions are greater on the arteries supplying skeletal muscle than on those supplying skin. It is used in the treatment of peripheral vascular disease and in premature labor. Duvadilan,Isoxsuprine Hydrochloride,Hydrochloride, Isoxsuprine
D008833 Microcirculation The circulation of the BLOOD through the MICROVASCULAR NETWORK. Microvascular Blood Flow,Microvascular Circulation,Blood Flow, Microvascular,Circulation, Microvascular,Flow, Microvascular Blood,Microvascular Blood Flows,Microvascular Circulations
D008875 Middle Aged An adult aged 45 - 64 years. Middle Age
D010865 Pilot Projects Small-scale tests of methods and procedures to be used on a larger scale if the pilot study demonstrates that these methods and procedures can work. Pilot Studies,Pilot Study,Pilot Project,Project, Pilot,Projects, Pilot,Studies, Pilot,Study, Pilot
D010973 Platelet Adhesiveness The process whereby PLATELETS adhere to something other than platelets, e.g., COLLAGEN; BASEMENT MEMBRANE; MICROFIBRILS; or other "foreign" surfaces. Adhesiveness, Platelet,Adhesivenesses, Platelet,Platelet Adhesivenesses
D001809 Blood Viscosity The internal resistance of the BLOOD to shear forces. The in vitro measure of whole blood viscosity is of limited clinical utility because it bears little relationship to the actual viscosity within the circulation, but an increase in the viscosity of circulating blood can contribute to morbidity in patients suffering from disorders such as SICKLE CELL ANEMIA and POLYCYTHEMIA.
