Abstract:

Acetaminophen and N,N-dimethylformamide (DMF) are compounds which are extremely toxic to the liver. Acetaminophen is a drug which is well known for its analgesic and antipyretic properties. However, the abuse potential of this agent as a non-narcotic analgesic in alcoholics is well known. It is also the leading cause of overdose in England. DMF toxicity results mainly from occupational exposure. At present there are no known reports of an antidote for DMF poisoning, while N-acetylcysteine, the antidote for acetaminophen poisoning, is known to produce adverse effects. The present study evaluate

Abstract:

The industrial solvent N, N-dimethylformamide (DMF) causes liver damage in humans. The hepatotoxicity of N-alkylformamides seems to be linked to their metabolism to N-alkylcarbamic acid thioesters. To clarify the role of metabolism in DMF hepatotoxicity, the metabolic fate of DMF was investigated in rodents. DMF was rapidly metabolised and excreted in the urine as N-hydroxymethyl-N-methyl-formamide (HMMF), N-acetyl-S-(N-methylcarbamoyl) cysteine (AMCC) and a metabolite measured as formamide by GLC. At high doses (0.7 and 7.0mmo1/kg) a small proportion of the dose was excreted unchanged. AMCC,

Abstract:

N,N-Dimethylformamide (DMF) is a well-known chemical entity that is extensively used for pharmaceutical, biomedical and chemical applications. Previous research identified the need for the development of an effective dosage form for the systemic delivery of DMF due to its unique antiviral properties. For purposes of quality control and evaluation during pharmaceutical product development, development of an analytical method was required. A gas chromatographic (GC) method was developed with a flame-ionization detector (FID) on a carbowax packed glass column. 2-Methoxyethanol was used as interna

Typically, VMI studies involve state-selective detection of one particular fragmentation product, and so are often limited to the investigation of a single dissociation channel. By employing vac

Prior to electrospinning, the rheological properties were investigated which used to determine the relaxation time, solution viscosity, overlap and entanglement concentrations. In this study, we reveal the effects of solution properties and processing parameters on the morphologies of Taylor cone/jet/as-spun fibers. Light scattering technique with He-Ne laser source was carried out to measure the jet diameter

Abstract:

碩士<br>長榮大學<br>職業安全與衛生研究所<br>95<br>The merabolism of N,N-dimethylformamide （DMF） in a human body involves cytochrome P450 2E1 （CYP2E1） and glutathione-S-transferase （GST）. It has been known that these two enzymes own different kinds of genetic polymorphisms. The different genetic polymorphisms of the enzymes make the expressions of the enzyme activities for the metabolism of DMF and the health effects cause by DMF in humans become very different. The objectives of this study are: （1） to investigate the effects of genetic polymorphisms of CYP2E1 and GST on three urinary biomarkers, i.e., N-me

Abstract:

博士<br>國立成功大學<br>環境醫學研究所<br>97<br>It has been demonstrated that N-dimethylformamide (DMF) is toxic to liver and male sperms and known that DMF is also a skin penetrator. However, regarding the recognition and protection of skin exposure to DMF for industries are still inadequate. Both field study and laboratory study were executed in this study. The field study attempts to quantitatively determine the relative contribution of DMF vapor exposure via skin and inhalation route and to evaluate the protective effectiveness of various personal protective equipments (PPE). Laboratory study is aimed to

Abstract:

碩士<br>國立成功大學<br>環境醫學研究所<br>91<br>The major routes of chemical exposure for the subjects in the occupational environment are through respiratory tract and through dermal tract. However, continuous improvement exerted in the respiratory protection these days in the occupational setting has substantially reduced the absorbed amount via respiratory route. Dermal exposure, thus, has become increasingly important with respect to the protection of the workers from the chemical hazards. The purposes of this study were to determine the relative contribution of dimethylformamide (DMF) exposure via derma
