A review on the flow analysis of phosphorus with chemiluminescence detection is presented. A brief discussion of the chemiluminescence principles and applications is given. Particular emphasis is devoted to coupling different flow techniques (flow injection, sequential injection, multicommutation, multisyringe flow injection, multi-pumping) to chemiluminescence detection. Enzymatic and non-enzy...

Background & Aims: The anti TNF drugs are new line treatment for articular inflammatory diseases which are used systemically, but due to expensiveness and some systemic adverse effects have limited usage. The aims of this study were to investigate the effect of intra-articular (local) injection of Etanercept and Infliximab as two anti TNF drugs on histopathology and also due to the important ro...

A hydrogel was prepared by crosslinking aqueous solutions of sulfonated polyacrylamide/chromium triacetate for use in water shut off operations. Gel swelling and the effects of salinity, injection time and flow rate on residual resistance factor (Frr) were investigated. In the presence of electrolytes, gel swelling decreased by about 80%. Results showed that oil permeability increased as inject...

The study of interactions of jet into cross flow at different longitudinal and transverse angles of jet was studied. The following components were designed and constructed: a low velocity wind tunnel to produce the uniform flow, a flat plate with a traverse injection system to simulate the jet injection, and a spatial rake to measure the total pressure. The tests were carried out at longitudina...

The Effect of Intraarterial Papaverine on the Regional Cerebral Blood Flow in Patients with Stroke or Intracranial Tumor • The effect of intracarotid injection of 10 mg of papaverine on regional cerebral blood flow was measured in 27 patients. Most of the patients had cerebral infarction or intracranial neoplasm. The intra-arterial Xenon injection method was used and 16 or 35 regions of the dis...

Incorporation of a liquid waveguide capillary flow cell into a flow injection instrument enhances the sensitivity of flow injection analysis with spectrophotometric detection by two orders of magnitude. Nitrite determination at nM levels has been used to demonstrate the feasibility of this novel technique for trace analysis. Combining the long pathlength spectrophotometry with flow injection an...

OBJECTIVE Pathomechanism of coronary slow flow phenomenon remains largely unclear now. Present study observed the pathological and angiographic evolution in a pig model of coronary slow flow. METHODS Coronary slow flow was induced by repeat coronary injection of small doses of 40 µm microspheres in 18 male domestic pigs and angiographic and pathological changes were determined at 3 hours, 7 d...
