Fluorescein-induced Raynaud's phenomenon

Raynaud's phenomenon induced by sulphasalazine.

Sulphasalazine-induced Raynaud's phenomenon is reported in a patient who showed no other features of a drug-induced lupus syndrome. The vascular disturbance disappeared when the drug was withdrawn on 3 occasions. A simple technique for assessing the circulatory abnormality in Raynaud's phenomenon is described.

Fundus photography and fluorescein angiography Fluorescein angiography

Fluorescein angiography is a clinical diagnostic test procedure in which rapid-sequence photography is performed after intravenous injection of sodium fluorescein. The procedure allows the documentation of the retinal circulation. Of equal importance is the ability of the angiogram to outline the entire retinal vascular bed. Previous clinical methods of examination of the fundus enabled the phy...

Honey-Induced Protein Stabilization as Studied by Fluorescein Isothiocyanate Fluorescence

Protein stabilizing potential of honey was studied on a model protein, bovine serum albumin (BSA), using extrinsic fluorescence of fluorescein isothiocyanate (FITC) as the probe. BSA was labelled with FITC using chemical coupling, and urea and thermal denaturation studies were performed on FITC-labelled BSA (FITC-BSA) both in the absence and presence of 10% and 20% (w/v) honey using FITC fluore...

Tachycardia induced myocardial dysfunction. A reversible phenomenon?

Four patients with myocardial dysfunction related to tachycardia underwent electrophysiological studies, which showed a re-entrant supraventricular tachycardia using an accessory atrioventricular connexion. Serial assessment of left ventricular function by echocardiography before and after control of the tachycardia indicated a variable degree of reversibility. Endomyocardial biopsy in two pati...
