INTRODUCTION Dye containing paraphenylene diamine is not an uncommon cause of renal failure in South India. However, there are very few published reports on renal lesions associated with hair dye ingestion. MATERIAL AND METHODS We studied 30 consecutive cases (24 males and 6 females) of hair dye induced renal failure seen at our department. All the patients were aged between 18 to 40 years (2...

Hair cells in mouse cochlear cultures are selectively labeled by brief exposure to FM1-43, a styryl dye used to study endocytosis and exocytosis. Real-time confocal microscopy indicates that dye entry is rapid and via the apical surface. Cooling to 4 degrees C and high extracellular calcium both reduce dye loading. Pretreatment with EGTA, a condition that breaks tip links and prevents mechanotr...

BACKGROUND Para-phenylenediamine (PPD) is the primary patch test screening agent for hair dye contact allergy (HDCA). However, no recent studies have been published that describe the results of reactions to patch tests using PPD and hair dyes in Korea. OBJECTIVE To analyze the results of the patch tests to PPD using the thin-layer rapid use epicutaneous (TRUE) Test system in patients with HDC...

We describe two female patients aged 31 and 62 y who developed severe aplastic anaemia following the use of hair dye containing para-toluenediamine. One received a bone marrow transplant but died after developing graft versus host disease and severe opportunistic infection. The second responded to treatment with methylprednisolone, oxymetholone and antithymocyte globulin and 3 y later she has a...

Within the bullfrog semicircular canal crista, hair cell tuft types were defined and mapped with the aid of scanning electron microscopy. Intracellular recording and Lucifer Yellow labeling techniques were used to study afferent responses and arborization patterns. Dye-filled planar afferent axons had mean distal axonal diameters of 1.6-4.9 microns, highly branched arbors, and contacted 11-24 h...

Hair dye is a cosmetic preparation intended to give the hair new color or restore original color. Purple sweet potato tuber skin contains more anthocyanin that can be used in manufacture of preparations. The extract was prepared by maceration using 96% ethanol. dyes were made into 4 formulas: Formula 0 not added with concentration copper II sulfate, while Formulas 1, 2, and 3 sulfate concentrat...
