PARAPHENYLENEDIAMINE HAIR DYES

Archives of Dermatology, 1952
HAIR DYES have been used since ancient times. There is evidence that the ancient Egyptians, Greeks, and Romans used them. The hair dyes used by the ancients were vegetable in origin. Nutgalls, saffron, thapsia, 1 henna, indigo, camomile, sage tea, and many others were used for hair coloring. Dermatitis or systemic poisoning from hair dyes is not known

Avoiding Paraphenylenediamine Exposure in Children

Pediatric Annals, 2008
<P>Paraphenylenediamine (PPD) is a chemical substance that turns black in the presence of an oxidizer and functions effectively as permanent hair dye. Unfortunately, the intermediary state (partially oxidized) is highly sensitizing and has resulted in bullous contact dermatitis with scarring in some individuals.

Paraphenylenediamine

Journal of Neuropathology and Experimental Neurology, 1983
Morphologic investigations of the human visual pathways have been limited by the infeasibility of modern neuroanatomical approaches. Although contemporary methods for tracing axon pathways (such as tracer injections and electrophysiology) have elucidated the visual system in experimental animals, these techniques cannot be similarly applied in humans ...

Paraphenylenediamine Containing Hair Dye

American Journal of Forensic Medicine & Pathology, 2015
Paraphenylenediamine poisoning is among one of the emerging causes of poisoning in Asian countries, because it is a constituent of hair dye formulations and is easily available in market at low cost. Hair dyes are rampantly used in Asian households compared with the western world.

Morphology of Paraphenylenediamine‐Aniline Conducting Copolymers

Berichte der Bunsengesellschaft für physikalische Chemie, 1989
AbstractElectrooxidation of aniline on conductive substrates, in an aqueous chloride electrolyte at low pH, produces adherent polyaniline (PANI) films. In the initial stage of polymerization the films exhibit a uniform globular microstructure which evolves to a fibrous deposit for thicker films.

CUTANEOUS B-CELL PSEUDOLYMPHOMA DUE TO PARAPHENYLENEDIAMINE

Dermatitis, 2006
Lymphomatoid contact dermatitis is a form of pseudolymphoma that was first described in 1976 by Orbaneja et al. Since that initial report, a number of allergens have been reported to cause this type of pseudolymphoma. Most cases involve hyperplasia of T cells. We describe a case of cutaneous B-cell pseudolymphoma due to paraphenylenediamine.

Rhabdomyolysis in paraphenylenediamine intoxication.

Veterinary and human toxicology, 1995
Edema of the upper airways and rhabdomyolysis developed in a young patient as a consequence of paraphenylenediamine poisoning. Treatment with adrenaline, steroids and enforced diuresis prevented tracheostomy and renal failure.

Dermal toxicity of paraphenylenediamine.

Biomedical and environmental sciences : BES, 1993
The guinea pigs were dermally exposed to paraphenylenediamine (PPD) and in presence of an oxidising agent hydrogen peroxide for 15 and 30 d to assess their effects on some enzymes, lipid peroxidation and histamine contents in the skin. The activities of acid and alkaline phosphatases, beta-glucuronidase, gamma glutamyl transpeptidase, histidase and ...

Rhabdomyolysis and Acute Renal Failure Induced by Paraphenylenediamine

Human Toxicology, 1989
1 We present a 40-year-old healthy man who developed a typical clinical picture of rhabdomyolysis following the administration of paraphenylenediamine by a witchdoctor as a pain killer. 2 Two groups of 15 mice were given paraphenylenediamine 70 mg/kg and 35 mg/kg respectively.
