To determine the long-term cutaneous side effects of methoxsalen phototherapy (PUVA) and Goeckerman regimen, a total of 151 Japanese psoriatic patients treated with PUVA, Goeckerman regimen, or both therapies in our department from 1976 to 1986 were evaluated for skin cancers. Sixty-seven patients
BACKGROUND
Systemic methoxsalen PUVA increases nonmelanoma skin cancer risk in a dose-dependent manner, whereas trioxsalen bath PUVA treatment has been suggested to be less carcinogenic.
OBJECTIVE
Our purpose was to study the carcinogenicity of topical trioxsalen PUVA.
METHODS
We performed a record
Background Androgen deprivation therapy (ADT) is a standard treatment for high-risk biochemically-recurrent, non-metastatic prostate cancer (BRPC) but is not curative and associated with toxicity. Racemetyrosine (SM-88) is an amino-acid analogue used with methoxsalen, phenytoin, and sirolimus (MPS)
Osteopenia or osteoporosis occurs frequently in alcoholics and patients with alcoholic fatty liver disease. Methoxsalen (MTS), 8-methoxypsoralen, improved osteoporosis in ovariectomized and diabetic mouse models; however, its effects on alcohol-induced osteopenia and steatosis have not been
Human microsomal cytochrome P450 2A6 (CYP2A6) contributes extensively to nicotine detoxication but also activates tobacco-specific procarcinogens to mutagenic products. The CYP2A6 structure shows a compact, hydrophobic active site with one hydrogen bond donor, Asn297, that orients coumarin for
Previously, we identified methoxsalen (8-methoxy-2',3',6,7-furocoumarin) as the bioactive compound probably responsible for acetylcholinesterase (AchE) inhibition achieved by feeding crude extract of Poncirus trifoliate. To confirm the activity of methoxsalen, Institute of Cancer Research (ICR) mice
The CYP2A6 gene spans a region of approximately 6 kb pairs consisting of 9 exons and has been mapped to the long arm of chromosome 19 (between 19q12 and 19q13.2). The CYP2A6 protein has 494 amino acids and is an important hepatic Phase I enzyme that metabolizes approximately 3% of therapeutic drugs
The tumorigenic properties of topical methoxsalen (8-MOP) and trioxsalen (TMP) plus ultraviolet light A (UVA) were studied in NMRI female mice. The animals were treated three times weekly for 9 months, and followed up for 18 months. Acetonic solutions of TMP (0.1 mg in 0.2 ml) and 8-MOP (0.6 mg in
OBJECTIVE
To assess the effectiveness, safety and cost-effectiveness of extracorporeal photophoresis (ECP) for the treatment of refractory erythrodermic cutaneous T cell lymphoma (CTCL) and refractory chronic graft versus host disease (cGvHD).
BACKGROUND
CUTANEOUS T CELL LYMPHOMA: Cutaneous T cell
Intramelanocytic lipid droplets have been observed in 12 patients with different types of hypermelanosis of the skin. These include drug-induced hypermelanosis, hypermelanosis secondary to use of physical agents, hypermelanotic morphea, generalized scleroderma with diffuse hypermelanosis, a
Oral administration of 8-methoxypsoralen followed by exposure to longwave ultraviolet light (primarily ultraviolet A, 320-400 nm) is used in the treatment of vitiligo and psoriasis. 8-Methoxypsoralen also occurs naturally in a variety of vegetables. Toxicology and carcinogenesis studies of
Botanical extracts and single compounds are increasingly used in cosmetics but also in over-the-counter drugs and food supplements. The focus of the present review is on controlled clinical trials with botanicals in the treatment of acne, inflammatory skin diseases, skin infections, UV-induced skin
BACKGROUND
Extracorporeal photopheresis (ECP) involves ex vivo leukocyte treatment with methoxsalen and UVA light to generate a tolerogenic response. A previous trial demonstrated that ECP permits corticosteroid withdrawal in steroid-dependent Crohn's disease (CD) patients who were in clinical
The seeds of A. graveolens yielded coumarin derivatives such as seselin, methoxsalen, and 3H-isobenzofuran-1-one through chromatographic separation techniques. The structure of the components has been established on the basis of spectral data analysis. The present study was undertaken to explore the
In 1998 it is appropriate to commemorate the 50th anniversary of el Mofty's use of purified 8-methoxypsoralen (8-MOP) in the treatment of vitiligo (el Mofty AM. A preliminary clinical report on the treatment of leukoderma with Ammi majus linn. J R Egypt Med Assn 1948,31:651 65. el Mofty AM, el
