BACKGROUND Unintended perfusion of the gastroduodenum may complicate hepatic arterial chemotherapy leading to mucosal ulceration. PATIENTS AND METHODS In a review of 233 consecutive hepatic artery catheters placed, 61 patients were investigated for chemotherapy-related epigastric pain. Investigations included catheter imaging, upper gastrointestinal endoscopy with methylene blue injection via...

In this paper, the photochemical degradation of azure-b by Cu2+/S2O82− process has beenpresented. Cu2+ as photocatalyst and S2O82− ion as photooxidant used in this process. Atextremely low concentrations, cupric ion showed true catalytic activity in the overall process.The influence of various parameters on the performance of the treatment process has beenconsidered, such as pH, concentration o...

We present a large comparative series of trypan blue use in cataract surgery. This series of trypan blue used in all eyes regardless of cataract severity may be unique. We found an apparent increased rate of cystoid macular oedema (CMO) associated with trypan blue use. Melles et al’s report on the use of trypan blue in cataract extraction in 1999 combined with Apple et al’s series on dye enhanc...

biosorption of acidic dyes using the live fern azolla filliculoides was studied in a discontinuous system. dye parameters, dye initial concentration and contact time were studied in temperature range of 25-30 ?c and ph=7. it was shown that increasing the 23initial concentration of dye and its contact time resulted in decreasing the dye taking quantity by the absorbent. also, type of dye has an ...

Disruption of the blood-brain barrier may play a major role in the pathogenesis of hypertensive encephalopathy. In this study we determined whether sympathetic nerves to cerebral vessels protect the blood-brain barrier during chronic hypertension. We removed the cervical sympathetic ganglion on one side in 24 stroke-prone hypertensive rats when they were 1 month old. After signs of cerebral dys...

Simple, fast and reproducible methods were developed for the determination of Tolterodine tartrate (TOL), the first method (method A) was based on the oxidation of the drug using permanganate in acidic medium in the presence of methylene blue dye and estimation of (TOL) by measuring the absorbance of the residual amount of methylene blue dye at 600 nm, in (method B) the drug amount was estimate...

INTRODUCTION Methylene blue dye has been used worldwide successfully with few complications in breast surgery. We present two different complications involving methylene blue: 1) skin and parenchymal necrosis when dye was injected in a subdermal fashion and 2) Mycoplasma infection caused by contaminated methylene blue in breast reduction surgery. METHODS We present two cases seen at the Unive...

A bacterial strain (strain PS) was isolated from the textile effluents carrying Serilene Black BNFS® (C.I. Disp. Blk. Mix) disperse dye. The isolate was able to decolorize the dye without the need for any exogenous carbon source. Full sequencing of its 16S rRNA indicated that Bacillus sp strain PS is related to Bacillus cereus groups.  Silica- gel-thin layer chromatography of Ser...

Sentinel lymph node biopsy (SLNB) is a simple technique that uses subdermal or peri-tumoral injection of vital blue dye and/or radioactive isotope to identify the first lymph node(s) draining the primary tumor. It has been shown to accurately predict axillary node status in patients with clinically node negative breast cancer. The SLNB is emerging as a new standard of care in patients with earl...
