Acute arterial thromboembolism and venous thrombosis are limb-threatening and potentially life-threatening conditions. Acute arterial thrombus prohibits perfusion to affected limbs, resulting in emergent limb salvage situations. Acute lower extremity deep vein thrombosis (DVT) is a common condition that can cause substantial disability, with the most common feared complication being a life-thre...

A simple, economical, precise and fast visible spectrophotometric method has been developed for the determination of Azathioprine in tablet dosage form. Developed method is based on the formation of extractable colored complex of drug with colouring agent Indigo Carmine and Methyl orange. A wavelength maximum was found to be 683.7 nm and 566 nm. The concentration range of 15-50 μg mL-1 with of ...

AChineseHerb, IndigoNaturalis, Extracted in Oil (Lindioil) Used Topically to Treat Psoriatic Nails: A Randomized Clinical Trial Indigo naturalis, a Chinese herb, has been used for decades.1 Olive oil was used to remove the blue component within indigo naturalis to yield a purple-red product to treat skin and nail psoriasis without obvious staining.2,3 This trial compared indigo naturalis extrac...

Indigo and indirubin have been reported to be present at low levels in human urine. The possibility that indigoids are physiological ligands of the aryl hydrocarbon receptor (AhR) has been suggested by initial studies in yeast, where indirubin was found to be 50 times more potent than 2,3,7,8-tetrachlorodibenzo[p]dioxin (TCDD), and indigo was found to be equipotent. To demonstrate that these in...

The degradation of the dye indigo carmine in aqueous solution induced by two oxidative processes (H(2)O(2)/iodide and O(3)) was investigated. The reactions were monitored by electrospray ionization mass spectrometry in the negative ion mode, ESI(-)-MS, and the intermediates and oxidation products characterized by ESI(-)-MS/MS. Both oxidative systems showed to be highly efficient in removing the...

Passive samplers with two different collection substrates were used to obtain an average ozone concentration for 1 month during the summer of 2002 for each South Carolina county. One sampler contained a filter coated with indigo carmine, whose color fades when exposed to ozone. The fading was measured by reflectance spectroscopy. The other sampler contained filters that were coated with nitrite...
