Using our previously reported "thalamic infarction model in the dogs", it was found that hemorrhagic infarction can be produced at a high frequency following recirculation after 6-12 hours of vascular occlusion. In the present study, in order to elucidate the pathophysiology of hemorrhagic infarction, we have undertaken a study of the relations among the histological findings, degree of ischemi...

purpose : to report a patient with branch retinal vein occlusion (brvo) and serologic evidence of primary cytomegalovirus (cmv) infection case report : we have reported a 27-year-old male with a complaint of sudden decrease in right eye vision starting a few days before. results : immunoglobulin g (igg) seroconversion indicated primary cmv infection. conclusion : involvement and obstruction of ...

   Introduction: Retinal vein occlusion  is a common vascular disorder disrupting vision. Two basic types of RVO are branch retinal vein occlusion and central retinal vein occlusion (CRVO).  Retinal vein occlusion is a multifactor process including systemic illness and local retinal factors.RVO may be associated with atherosclerotic risk factors. We analyzed the role of 2 dimensional transthor...

Each vascular occlusion technique has a place in major and minor hepatic resectional surgery, based on the tumor location, presence of associated underlying liver disease, patient cardiovascular status, and experience of the operating surgeon. Understanding of the potential application of different techniques, anticipation of the expected and potential hemodynamic responses, and knowledge of th...

PURPOSE The purpose of this research was to assess associations of thrombophilia with central retinal vein occlusion (CRVO), central retinal artery occlusion (CRAO), and amaurosis fugax (AF); to evaluate outcomes of normalizing high homocysteine; and to study CRVO, CRAO, and AF developing in estrogens/estrogen agonists in women subsequently shown to have thrombophilia. METHODS Measures of thr...

BACKGROUND Significant hemorrhage together with blood transfusion has negative impact on postoperative morbidity, mortality, and long-term survival of liver resection. Various techniques of vascular occlusion have been developed to reduce intraoperative blood loss. The objective of this study was to compare the outcomes of Pringle maneuver, hemi-hepatic vascular occlusion, and treatment without...

BACKGROUND Recent studies have shown that endothelial proliferation and angiogenic response are characteristic of degenerative events, such that the magnitude of endothelial activation is reflective of the progression of neurodegeneration. PURPOSE This study sets out to, compare, the degenerative changes seen in the parietal cortex (PC) and periventricular zone (PVZ) after cyanide toxicity or...

Objective(s):The major objective of the present study was to investigate the potential neuroprotective effect of berberine chloride on vascular dementia. Berberine, as an ancient medicine in China and India, is the main active component derived from the Berberis sp. Several studies have revealed the beneficial effects of berberine in various neurodegenerative disorders. Materials and Methods: T...

OBJECTIVE To determine the efficacy of antiplatelet therapy in maintaining vascular patency in various categories of patients. DESIGN Overviews of 46 randomised trials of antiplatelet therapy versus control and 14 randomised trials comparing one antiplatelet regimen with another. SETTING Randomised trials that could have been available by March 1990 and in which vascular graft or arterial p...

The aim of this study was to investigate the heart rate variability (HRV) after resistance training with and without vascular occlusion. It was hypothesized that low intensity (LI) with vascular occlusion (LIO) would elicit comparable postexercise HRV responses with that of high intensity (HI) without vascular occlusion. Nine subjects undertook 4 experimental sessions of leg press exercise on d...
