There were investigated 15 cases with normal thymus removed during cardiac surgery and nine cases with clinical signs of myasthenia gravis. Four patients with myasthenia gravis had thymoma (three invasive, one non-invasive). Specimens were fixed in buffer formalin, embedded in paraffin and slides were stained with Hematoxylin-Eosin and Alcian blue-Safranin. Additional slides were stained for fa...
The role of tumor-associated macrophages (TAMs) in hepatocellular carcinoma (HCC) has not been fully investigated. The aim of the present study was to clarify whether TAMs are associated with the angiogenesis of HCC during its multistep development, especially at an early stage. Forty-three well-differentiated HCCs and 30 wellto moderately differentiated HCCs (nodule-in-nodule lesion) were used...
We developed a rat model of pulmonary arteriovenous malformations after cavopulmonary anastomosis. We sought to determine whether this model reproduces the angiographic and histologic features seen in the human condition. Eight Sprague-Dawley rats underwent a right superior cavopulmonary anastomosis with the use of microsurgical techniques. Between 2 and 13 mo, pulmonary angiography was perform...
Angiotensin II is known to stimulate angiogenesis in the peripheral circulation through activation of the angiotensin II type 1 (AT1) receptor. This study investigated the effect of angiotensin receptor blockade on cerebral cortical microvessel density. Rats (6-7 wk old, n = 5-17) were instrumented with femoral arterial and venous indwelling catheters for arterial blood pressure measurement and...
Introduction: Ameloblastoma is a benign epithelial odontogenic tumor that exhibits a more aggressive behavior than follicular cyst and keratocystic odontogenic tumor. The purpose of the current study was detection and evaluation of microvessel density (MVD) effect on growth and clinical behavior of above odontogenic lesions with immunohistochemistry. Materials & Methods: In this descriptive-ana...
