Indigo carmine is a blue dye that is widely applied to localise ureteral orifices. It is generally believed to be a safe, biologically inert substance, and hypotensive reactions are extremely rare. However, we experienced three cases of indigo carmine-induced hypotension within a period of two weeks.

BACKGROUND Identifying a precise demarcation line (DL) is indispensable for pathological complete en bloc endoscopic submucosal dissection (ESD) for early gastric cancer (EGC). We evaluated the useful condition of chromoendoscopy with indigo carmine and acetic acid for marking dots around lesions before ESD for EGC. METHODS We examined 98 consecutive patients with 109 intramucosal EGCs (mean ...

Intradermal injections of indigo carmine for sentinel node mapping are considered safe and no report of an adverse reaction has been published. The authors described two cases of profound hypotension in women that underwent breast-conserving surgery after an intradermal injection of indigo carmine into the periareolar area for sentinel node mapping.

Double-balloon endoscopy facilitates endoscopic retrograde cholangiopancreatography (ERCP) in patients with a Roux-en-Y anastomosis [1]. However, it is difficult to identify the afferent limb during double-balloon ERCP [2]. According to retrospective data from February 2007 to January 2009, the rate of accurate identification was 50% (14/28). We report a useful technique to identify the afferen...

fold increased risk of developing enterop− athy−associated T−cell lymphoma com− pared with the general population [1]. Early diagnosis is therefore required to improve their prospects. Indigo carmine chromoendoscopy highlights mucosal ir− regularities and improves the detection of malignant lesions [2]. Furthermore, it can delineate villous atrophy in celiac dis− ease [3]. This method is common...

Mechanism of Indigo carmine dye adsorption on palm wood cellulose activated carbon (PWCAC) was studied. The use of low cost ecofriendly adsorbent has been investigated as an ideal alternative to the current expensive methods of removing dye from aqueous solution. The study is done by batch adsorption techniques. The quantitative adsorption kinetic and equilibrium parameter for indigo carmine dy...

This study was undertaken to prove that the selectively infiltrated parts of nucleus pulposus with indigo carmine was degenerated parts of nucleus pulposus. This study was done, between August and October 2002, in 5 patients, who received endoscopic discectomy, due to intervertebral disc herniation. Discogram was done with mixture of indigo carmine and radioactive dye. Blue discolored part was ...

Methylene blue, which, unlike indigo carmine, is taken up by cells, induces cellular DNA damage in vitro via the generation of singlet oxygen when photoexcited by white light.4 In contrast, indigo carmine appears to be photostable and to possess little potential to damage genetic material in vitro.5,6A recent clinical study has shown that the extent of DNA damage (particularly oxidative DNA dam...

ODC 232.318: 174.7-01.5.4 In this investigation the results o f germinability o f ten samples each o f Pinus silvestris and Picea abies seed by the indigo carmine and the x-ray contrast methods are compared with their germination values on Jacobsen apparatus. T w o dif ferent criteria, namely those o f Hao (1939) and Krzeszkiewicz (1939) were used for judging the gerrninability by the indigo ca...

Indigo carmine (also known as 5,5'-indigodisulfonic acid sodium salt or indigotine) is a blue dye that is administered intravenously to examine the urinary tract and usually is biologically safe and inert. Indigo carmine rarely may cause adverse reactions. We treated a 66-year-old man who had general anesthesia and radical retropubic prostatectomy for prostate cancer. He had a previous history ...
