The aim of the present study was to report the importance of pegaptanib sodium (PGSD) injection treatment for vascular active vitreoretinopathy (VAVR). A total of 82 patients with VAVR diagnosed by increasing subretinal exudation were enrolled and received a single intravitreal injection of PGSD. The efficacies of PGSD for patients with VAVR were analyzed using photography, fluorescein angiogra...

Microvascular extravasation, lamina propria flooding and luminal entry of plasma are key features of airway inflammation. We have suggested that the extravasated plasma moves across the epithelial lining along hydrostatic pressure gradients. The present study, involving healthy subjects, tests this hypothesis by examining effects of experimentally applied negative and positive luminal pressures...

The chemical compounds contained in leguminous plant root exudation induce structural and compositional transitions of the lipopolysaccharides of Rhizobium that occur during rhizobia-legume symbiotic infection processes. The root exudate was extracted from the seed germinated solution and seedling roots of soybean. We added the exudation to bacteria cultured medium. Rhizobium and Bradyrhizobium...

Zymosan-induced peritonitis was investigated in mast cell-deficient WBB6F1 mice and in Balb/c mice pretreated with mast cell stabilizer (cromolyn) or antagonists of histamine receptors (mepyramine, triprolidine, cimetidine, or ranitidine). The inherited mast cell deficiency in W/Wv knockouts of WBB6F1 mice impaired significantly the level of histamine and plasma exudation (measured 30 min after...

Hypertonic saline (HS) is used in sputum induction studies. However, little is known about the physiological effects of HS on human airways in vivo. The present study takes advantage of the fact that the airway effects of topical challenges may be accurately examined in the readily accessible nasal airway. The present study specifically examines whether exposure to HS affects histamine challeng...

The role of mast cell degranulation in increased vascular permeability in zymosan-air-pouch inflammation, an experimental model of inflammation induced by zymosan in rats, was investigated. The complement in the inflammatory pouch fluid was exhausted, and mast cells in the pouch wall subcutaneous tissues were degranulated. The histamine level in the pouch fluid was elevated immediately after ap...

Malate is a central metabolite of the plant cell with important roles in plant physiology and metabolism. Here, we summarize the most recent advances in our understanding of malate homeostasis in central metabolism, guard cell functioning, and root exudation.
