OBJECTIVE The work aimed to study the potential correlation between the high-level benzene exposure and its urinary metabolites S-phenylmercapturic acid (SPMA) and trans, trans-muconic acid (t,t-MA) in Chinese shoe-making workers. METHODS Individual benzene-exposed levels were determined by gas chromatography analysis, urinary t,t-MA, and urinary SPMA(More)
Interferon(IFN) stimulates the expression of a number of genes encoding enzymes with antiviral activities, including myxovirus resistance A(MxA) and double-stranded RNA-dependent protein kinase(PKR). PKR is also activated by dsRNA, this leads to the phosphorylation of eukaryotic initiation factor 2a(elF-2α), which halts viral replication. We investigated(More)
OBJECTIVE This study analyzed the level of urinary S-phenylmercapturic acid (U-SPMA) for low benzene exposure in a group of Chinese shoe-making workers. METHODS Urinary samples from 55 workers exposed to benzene at levels lower than 10 parts per million (ppm) were collected at postshift. U-SPMA level was determined using high-performance liquid(More)
OBJECTIVE To investigate the possible effects on nervous system and health condition under the exposure to electromagnetic field. METHODS Take the resident around the power transmission line as the objects and were divided into 3 groups by the distance from the power transmission line 20 m, 100 m and 500 m, respectively. Some living conditions and health(More)
OBJECTIVE To investigate the relationship between trans, trans-muconic acid (ttMA) as benzene metabolite of occupational workers and benzene concentration in air. METHODS A rapid and sensitive high-performance liquid chromatography was developed to determine the level of urinary ttMA. ttMA was extrated from urinary samples in liquid-liquid phase a ODS (2)(More)
OBJECTIVE To establish health protection zone standards for petroleum processing industry. METHODS The intensity of characteristic pollutants from fugitive emission were estimated by the inverse method of ground concentration through field survey and monitoring for representative petroleum processing industry, which was calculated health protection zone(More)
AIM To study the effect of manganese (Mn) on heat stress protein 70 (HSP70) synthesis in the brain and liver of new-born rats whose mother-rats were exposed to Mn. METHODS 32 female rats were randomly divided into four groups. One group was administrated with physiological saline only as control group, the other three groups were administrated with 7.5,(More)
OBJECTIVE To establish the biological exposure limit values of urinary S-phenylmercapturic acid (SPMA) for assessing occupational exposure to benzene. METHODS Study participants were selected from 55 workers of benzene exposures below 32.5 mg/m(3). The concentration of personal exposure to benzene was measured by gas chromatography and sampled with(More)
