Inactivated whole avian influenza virus (AIV) vaccine provides protection against homologous haemagglutinin (HA) subtype virus, but poor protection against a heterologous HA virus. Moreover, it induces chickens to produce antibodies to cross-reactive antigens, especially nucleoprotein, which is limits AIV serological surveillance. In this study, a(More)
BACKGROUND The present study was designed to investigate if hydrogen sulfide (H2S), a novel gasotransmitter, might have a regulatory effect on cardiac function and structure, as well as oxidative stress, in adriamycin (ADR)-induced cardiomyopathy. METHODS AND RESULTS Hemodynamic measurements, histopathological examination and stereological ultrastructural(More)
Ewing sarcoma-primitive neuroectodermal tumors (ES/PNET) constitute a family of neoplasms characterized by a continuum of neuroectodermal differentiation. ES/PNET of the uterus is rare. There are 43 cases published in the English literature as far as we know. We describe an additional case. A 56-year-old woman presented with a 2-month history of irregular(More)
OBJECTIVE Hypoxic pulmonary hypertension is an important pathophysiologic process of various cardiovascular diseases. Sulfur dioxide (SO2) was considered as a kind of toxic gas previously, but recent studies suggested that SO2 could act as a key bioactive molecule in the pathogenesis of cardiovascular diseases. Therefore, this study was designed to examine(More)
BACKGROUND The number of Clara cells and the Clara cell 16-kDa protein (CC16) levels of the lung decrease in patients with chronic obstructive pulmonary disease (COPD). N-acetylcysteine (NAC) is a powerful antioxidant and can reduce the frequency of acute exacerbations of COPD. But the exact mechanism is unclear. The present study was designed to(More)
OBJECTIVE To investigate the pathological characters and the corresponding clinical significance of internal hemorrhoids tissues. METHODS Normal anal cushion and internal haemorrhoids tissue samples were obtained after stapled haemorrhoidectomy procedure from 24 grade III hemorrhoidal patients. The macroscopically normal cushions served as own controls(More)
UNLABELLED To explore the changes of time-dependent pulmonary artery structural remodeling in pulmonary hypertension induced by high pulmonary flow in rats. METHODS Eighty male SD rats were randomly divided into control group (n =40) and shunt group (n = 40). Rats in shunt group were subjected to an abdominal aorta-inferior vena cava shunt to create an(More)
OBJECTIVE To investigate the pathological variations in internal hemorrhoid and evaluate the expression of nitric- oxide synthase(NOS),vascular endothelial growth factor(VEGF),matrix metalloproteinase- 2(MMP2) and MMP9. METHODS Normal anal cushion and internal hemorrhoids tissue samples were obtained from 24 patients with iii degree hemorrhoids after(More)
OBJECTIVE To investigate the clinicopathological manifestations of early renal amyloidosis (AL) and its diagnostic criteria. METHODS Fifteen cases with early renal amyloidosis admitted from 1994 to 2001 were collected from the hospital, and their clinical and pathological features were reviewed. Of them, the initial diagnoses were not made by depending(More)
OBJECTIVE To investigate the pathologic features and diagnostic algorithm of light chain nephropathy (LCN). METHODS Seven cases of LCN were studied by light microscopy, electron microscopy and immunolabeling of light chains (kappa, lambda) by immunofluorescence and immunoelectron microscopy. RESULTS The histopathology of 7 cases by light microscopy was(More)
