The purpose of the present study was to investigate whether cilostazol, a phosphodiesterase-III inhibitor and antiplatelet drug, would prevent tPA-associated hemorrhagic transformation. Mice subjected to 6-h middle cerebral artery occlusion were treated with delayed tPA alone at 6 h, with combined
OBJECTIVE
The Cilostazol Stroke Prevention Study II has shown a similar efficacy in stroke prevention but markedly fewer hemorrhagic events with the phosphodiesterase inhibitor cilostazol versus aspirin. The purpose of this study is therefore to investigate how cilostazol affects cerebral
OBJECTIVE
One of the phosphodiesterase isoenzymes, Type V (PDE V), specifically hydrolyzes cyclic guanosine monophosphate to cause vasoconstriction. This study analyses the effect of PDE V inhibition with sildenafil citrate (SC) on cerebral vasospasm and its effect on apoptotic changes of the
Cyclic GMP (cGMP) mediates smooth muscle relaxation in the central nervous system. In subarachnoid hemorrhage (SAH), decreases in intrinsic nitric oxide (NO) cause cerebral vasospasms due to the regulation of cGMP formation by NO-mediated pathways. As phosphodiesterase type V (PDE V) selectively
BACKGROUND
Selective inhibition of phosphodiesterase type III (PDE III) may be involved in the pathophysiology of vasospasm and a PDE III inhibitor, cilostazol, is thus expected to attenuate vasospasm after subarachnoid hemorrhage (SAH). We tested the therapeutic effects of cilostazol on
BACKGROUND
Phosphodiesterase-5 (PDE-5) inhibitors enhance penile erection and have gained popularity not only for erectile dysfunction, but also in recreational settings. Nevertheless, adverse effects have been associated with their use, with nasal bleeding among them. PDE-5 inhibitor action is
BACKGROUND
despite the years of study on it, cerebral vasospasm following subarachnoid hemorrhage is still an important cause of mortality and morbidity. The presented study was undertaken to show whether phosphodiesterase inhibitor tadalafil can attenuate the vasospasm process following
BACKGROUND
Scrotal hemorrhage after testicular sperm aspiration (TESA) is uncommon in clinical operation. Phosphodiesterase-5 inhibitors (PDE5i) are commonly given to men who have difficulty providing a sperm sample for assisted reproductive technique such as in vitro fertilization. In this study,
Intracerebral hemorrhage occurs when a diseased blood vessel within the brain bursts. We present a case of 69-year-old patient with two sequential episodes of lobar intracerebral hemorrhage occurring during sexual intercourse. Both episodes were associated with the use of phosphodiesterase-5
Objectives: Rapid loss of blood volume causes ischemic injury to myocardial cells and impairs cardiac function. Subsequent reperfusion, although necessary to revitalize stunned tissues, can induce production of reactive oxygen species and
OBJECTIVE
To investigate the protective roles of type 4 phosphodiesterase (PDE4) inhibitor in cyclophosphamide (CYP)-induced haemorrhagic cystitis, as the PDE4 inhibitor has anti-inflammatory effects but its characterization is still unknown in urinary tract diseases.
METHODS
In female
A combination of low-dose aspirin (ASA) and a phosphodiesterase inhibitor has been clinically tried for the secondary prevention of atherothrombotic diseases. The in vivo antithrombotic property of ibudilast (CAS 50847-11-5), a phosphodiesterase 4 (PDE4) inhibitor, was evaluated in a
UNASSIGNED
A 53-year-old woman with coma was diagnosed with subarachnoid hemorrhage and ruptured aneurysm at the right internal carotid-posterior communicating artery.
UNASSIGNED
The aneurysm was successfully clipped. Severe hypoxia and shock with abnormal left ventricular contraction were observed.
Neutrophils are activated following hemorrhagic shock and the accumulation of neutrophils in the lung is associated with lung injury. This research investigated the effects of a semisynthetic 2-benzoylaminobenzoic acid derivative, methyl 2-(2-fluorobenzamido)benzoate (DSM-RX78), on superoxide anion
BACKGROUND
Cerebral vasospasm is an independent predictor of poor outcome after subarachnoid hemorrhage (SAH). The nitric oxide-cyclic guanosine monophosphate (NO-cGMP) vasodilatory pathway is strongly implicated in its pathophysiology. Preliminary studies suggest that phosphodiesterase 5 (PDE5), an
