Until recently, various therapies for localized scleroderma have been used with limited success. Recently, phototherapy, with or without psoralen, was proposed as a successful treatment modality. The aim of this study was to evaluate the effect of broad-band low-dose ultraviolet A (UVA) phototherapy in patients with localized scleroderma, using a new method(More)
Traditional herbal medicines, popularly known as 'jamu' and 'makjun' in Malaysia and Indonesia, are consumed regularly to promote health. In consideration of their frequent and prolonged consumption, the natural occurrence of aflatoxins (AF) in these products was determined using immunoaffinity column clean-up and high-performance liquid chromatography with(More)
Because of the importance of neural recognition molecules expressed by glial cells to mediate interactions with neurons, growth factors and cytokines known to be functional during morphogenesis and in diseases of the nervous system were studied for their effects on recognition molecule expression by cultured immature and mature astrocytes from several brain(More)
The role of oxygen tension, insulin, and glucagon on the preservation and induction of cytochrome P450 isoenzyme activities and contents was investigated in rat hepatocytes cultured for 4 days on crude liver membrane fractions at 4 or 13% O2. At 13% O2, three out of six immunochemically analyzed P450 isoenzymes were significantly higher than in 4% O2.(More)
Twenty-nine plant extracts of local species were evaluated for their potential as a source of bioactive ingredients with significant acaricidal activity that could lead to the development of new and safe bio-acaricides. The crude extracts (70% ethanol) of these plants were tested for their acaricidal activity against the carmine spider miteTetranychus(More)
The regulation of acute-phase protein production and nitric oxide (NO) release in lipopolysaccharide-induced liver injury is thought to occur in response to monocytes/macrophages and Kupffer-cell-derived cytokines. In this study, we used primary cultured rat hepatocytes maintained as a differentiated phenotype to investigate the direct effects of endotoxin(More)
The influence of periportal- and centrilobular-equivalent oxygen tensions on cellular functions and xenobiotic metabolism was investigated in rat hepatocytes cultured under 20% (air/CO(2)), 13% or 4% O(2) for up to 9 days on teflon membrane dishes, coated with crude membrane fractions and collagen. Protein content, total cytochrome P-450 content,(More)
The influence of cell-substrata interactions on the preservation of basal or in-vivo-induced microsomal cytochrome P-450 isoenzyme contents in cultured rat hepatocytes and on the adaptive responses after exposure to phenobarbital or 3-methylcholanthrene in vitro, was investigated. Hepatocytes from untreated or phenobarbital-treated rats were cultured in(More)
