BACKGROUND Skin pigmentary changes of pityriasis versicolor may occur as either hyperpigmented or hypopigmented lesions, depending on the outcome of interactions between Malassezia yeasts and the skin, such as lipoperoxidation process, stimulus of inflammatory cell to melanocytes, and increased thickness of keratin layer. OBJECTIVE To investigate skin characteristic factors that enhance the s...

Since the recent introduction of a drug regimen containing 2 mg of the antiandrogen cyproterone acetate and 50 micrograms ethinyl-oestradiol (Diane; oestrogen-cyproterone acetate) several uncontrolled reports have extolled the benefits of this drug. Double blind studies, however, are lacking. Sixty two patients with moderate or moderately severe acne were therefore included in a double blind tr...

ABSTRACT The present study was conducted to investigate the effects of dietary fiber on growth performance, fat deposition, serum lipids, metabolism, and mRNA (messenger RNA) expression lipoprotein lipase (LPL) in Jilin white Carlos geese. Sixty sixty geese aged six-weeks similar health weight (average 313.11g) were selected. Geese each breed randomly divided into two groups (n=30), with group ...

Increasing evidence has identified ultraviolet radiation (UVR) as the skins most potent mutagen as over exposure results in sunburn, inflammation and DNA damage, thus contributing to a photo-ageing phenotype and possibly skin carcinogenesis. The lipid-rich sebum secreted onto the surface of the skin plays an important physiological role in protecting the skin against external challenges. When s...

Acne vulgaris does not always respond to conventional therapy. Photodynamic therapy (PDT) has been proposed as a treatment option. The aim of this study was to determine the optimal light dose for effective PDT treatment of acne and to investigate whether PDT reduces sebum excretion and the amount of Propionibacterium acnes. Fifteen patients (9 men, 6 women, age range 16-44 years, mean age 25 y...

BACKGROUND The deposition of cannabinoids on/into hair from environmental smoke can be considered as a potential source of drug findings in hair. We studied external uptake of cannabinoids from marijuana smoke, investigating possible influencing factors on drug uptake and the efficiency of decontamination procedures. METHODS Strands of a natural hair sample were moistened with water, greased ...
