THERE are few reports in the literature of experimental work dealing with the effect of cortisone upon corneal vascularization, and the evidence so fair advanced is partly conflicting (Duke-Elder and Ashton, 1951), but there is already some indication from clinical observers that cortisone exerts a considerable inhibitory influence on the formation of ne\v vessels in the diseased cornea. The ex...

BACKGROUND/PURPOSE The key challenge in tissue engineering is the establishment of an efficient vascularization for tissue constructs guaranteeing long-term survival and function. Vascularization may be achieved by the stimulation of angiogenesis or the inosculation of preformed microvascular networks within the implants to the host microvasculature. The present review provides an overview of t...

OBJECTIVE Proper development of retinal blood vessels is essential to ensure sufficient oxygen and nutrient supplies to the retina. It was shown that polyunsaturated fatty acids (PUFAs) could modulate factors involved in tissue vascularization. A congenital deficiency in ether-phospholipids, also termed "plasmalogens", was shown to lead to abnormal ocular vascularization. Because plasmalogens a...

INTRODUCTION AND PURPOSE Various conditions may cause vascularization of the normally avascular cornea. The aim of the present study was to create a reproducible experimental model that could enable the investigation of the phenomena leading to corneal vascularization. This involved creating a software to record the experimental data, enabling a subsequent digital analysis based on the growth m...

Both platelet-rich plasma (PRP) and vascular endothelial growth factor (VEGF) can promote regeneration. The aim of this study was to compare the effects of these two elements on bone formation and vascularization in combination with bone marrow stromal cells (BMSC) in a critical-size bone defect in rabbits. The critical-size defects of the radius were filled with: (1) a calcium-deficient hydrox...

Bone formation and osseointegration of biomaterials are dependent on angiogenesis and vascularization. Angiogenic growth factors such as vascular endothelial growth factor (VEGF) were shown to promote biomaterial vascularization and enhance bone formation. However, high local concentrations of VEGF induce the formation of malformed, nonfunctional vessels. We hypothesized that a continuous deliv...

The repair of bone defects with biomaterials depends on a sufficient vascularization of the implantation site. We analyzed the effect of pore size on the vascularization and osseointegration of biphasic calcium phosphate particles, which were implanted into critical-sized cranial defects in Balb/c mice. Dense particles and particles with pore sizes in the ranges 40-70, 70-140, 140-210, and 210-...

PURPOSE In the present study, the three-dimensional power Doppler was used as a quantitative method to evaluate its reliability in detecting and assessing of gestational trophoblastic disease (GTD). METHODS 52 GTD patients who received diagnosis and treatment at the first affiliated hospitals of Xi'an Jiaotong University in China between 2011 and 2013 were evaluated using Voluson E8 (GE Medic...

OBJECTIVE To assess the correlation between intratumoral vascularization using three-dimensional power Doppler angiography (3D-PDA) and several histological tumor characteristics in a series of patients with endometrial carcinoma. METHODS Ninety-nine women (mean age, 61.7 (range, 31-84) years) diagnosed as having endometrial cancer were assessed by transvaginal 3D-PDA before surgical staging....

OBJECTIVE Measurement of microvascularization and determination of its prognostic significance in cases of lung cancer. METHODS Section prepared from histological material from 432 radically operated non-small cell lung cancer patients were stained with antibodies against factor VIII-associated antigen. During computer imaging, the absolute and relative parameters of the vascularization were ...
