The combined effects of low doses of promoters or carcinogens on two-stage forestomach carcinogenesis were examined in rats pretreated with N-methyl-N'-nitro-N-nitrosoguanidine. Groups of 15 rats were given a single 150 mg/kg body weight intragastric dose of N-methyl-N'-nitro-N-nitrosoguanidine. Starting 1 week
Skin pharmacology : the official journal of the Skin Pharmacology Society, 1(2), 115-121 (1988-01-01)
Radical reactions of anthralin and its metabolites with skin have been studied by ESR spectroscopy. The influence of compounds which are known to suppress inflammation are described. The ESR spectra recorded during the reaction of anthralin with skin were essentially

The urinary bladder tumor-promoting potentials of the phenolic antioxidants, 2-tert-butyl-4-methylphenol (TBMP), propylparaben, catechol, resorcinol and hydroquinone, which are structurally related to butylated hydroxyanisole (BHA), were investigated in 170 male F344 rats. The animals were initially given 0.05% N-butyl-N-(4-hydroxybutyl)nitrosamine (BBN) as
Drugs with pH-dependent solubility that have poor water solubility can be identified in the drug discovery pipeline. Some of them have poor oral absorption, which can result in insufficient efficacy. Micro-environmental pH-modifying solid dispersion (micro pHm SD) is a promising
Metastasis is the main reason for cancer-associated mortality, and accurate diagnostic imaging of metastases is critical for the clinical administration and tailoring personalized treatments for metastatic tumors. However, magnetic resonance imaging of metastases in the liver is impeded by its
