OBJECTIVE
To investigate the emphasis of oxidative stress in the pathogenesis of vitiligo through an evaluation of ischemia-modified albumin (IMA). Results/methodology: IMA was of higher statistical significance in patients than in the control group (IMA: 0.57 ± 0.2 vs 0.52 ± 0.2 ΔABSU; p < 0.0001).
Purified transcobalamin I labeled with radioactive iodine and cobalamin was used for turnover studies in 17 humans. Mean fractional catabolic rate was 0.15 d-1 and mean distribution ratio was 0.57. No difference was observed between the turnover in a control group and in patients with vitiligo or
Increasingly used in therapeutics, 5-methoxypsoralen (5-MOP), a linear furocoumarin, associated with UVA irradiation (PUVA), is now an established treatment for skin diseases such as vitiligo, mycosis funcoides and particularly psoriasis. Successful PUVA therapy depends on a sufficiently high peak
Human serum albumin (HSA) is the most abundant protein in the circulatory system. Oxidized albumin was identified in the skin of patients suffering from vitiligo, a depigmentation disorder in which the protection against ultraviolet (UV) radiation fails because of the lack of melanin. Oxidized
Piperine, the major alkaloid of black pepper (Piper nigrum L.; Piperaceae), stimulates melanocyte proliferation and dendrite formation in vitro. This property renders it a potential treatment for the skin depigmentation disorder vitiligo. However, piperine does not stimulate melanin synthesis in
8-methoxypsoralen (8-MOP), 5-methoxypsoralen (5-MOP) and 4,5',8-trimethylpsoralen (TMP) are commonly used in PUVA therapy [psoralen (P) + ultraviolet light A (UVA) irradiation] to treat skin diseases such as psoriasis and vitiligo. In order to predict the choice of the suitable drug(s) for topical
BACKGROUND
Primary biliary cirrhosis (PBC) is a rare cause of chronic liver disease in India. We analyzed the clinical, biochemical, serological and histological features of patients with PBC for over a 10-year period.
METHODS
PBC was diagnosed by the presence of raised level of serum alkaline
BACKGROUND
Autoimmune hepatitis (AIH) has been reported to show considerable geographical variation in frequency and clinical manifestations. It is considered a rare cause of liver disease in India. The present study was undertaken to determine the incidence, clinical, biochemical and histological
Monobenzone (hydroquinone monobenzylether, 1) is a potent skin depigmenting agent that causes irreversible loss of epidermal melanocytes by way of a tyrosinase-dependent mechanism so far little understood. Herein, we show that 1 can be oxidized by mushroom tyrosinase to an unstable o-quinone
