| 1 | Effects of high voltage discharge on the human bodies of workers显示文摘In this paper,as it is reported,through mechanism analysis,calculation,testing,measuring in the site and the observation ofbiologic effect on workers as well as the peripheral blood test in vitro,there are low energy X-ray and so forth produced due to high volt-age discharge which are harmful physical and chemical factors.Theexistence of these harmful factors affect workers’ health to a certaindegree.The observed biologic indexes are those of peripheral bloodcell effect,lymphocyte,micronuclear,chromosomal aberration,sisterchromatid exchange,blood serum immune globulin,electroen-cephalogram and brain blood current gram. The vitro peripheralblood test indexes are including those of chromosmal aberration,sister chromatid exchange and blood serum immune globulin.Theresults obtained from the said observation and testing express thatthe above mentioned indexes have obvious significance after thecomparison of those between test group and control group treated bystatistics (i.e.P<0.05).Further,the test results also point out that theenvironment of high voltage discharge will creat injury to the workers,therefore a detail research should be taken. | Yang Baochu Chongqing UniversityZao Wenzhen Radiative medical Science Research Institute,Medical Science Academy of ChinaZhang Maohua Hygienic and Antiepidemic Station of Qijiang | 1991 | Electricity1991，，2： | 4 |
| 2 | Effect of methylmercury on LPO levels, SH groups and activities of GSH-Px, SOD, XOD in liver of rats显示文摘In recent years, lipid peroxidation has been considered as the initial step for foreign toxic substances to damage cells. In this paper, the effects of methylmercury (MeHg) on LPO (lipid peroxide) levels, SH (sulfhydryl) groups and activities of GSH\|Px (glutathione peroxidase), SOD (superoxide dismutase), XOD (xanthine oxidase) in liver of rats treated with doses of MeHg at different intervals were studied by TBA, Ellman Reagent, NBT colorimetric methods and chemilluminescence. Meanwhile, the contents of FR (free radical)and MeHg in the liver of female rats were measured by ESR and GC. Results showed that the LPO levels in the experimental group increased significantly over those of the control group ( p<0.05— p<0.001) , reaching maximum point on the first poisoning day. Both male and female rats showed marked positive dose\|effect relations (Male: Y=261.4±49.4X, r=0.94, p<0.02; Female : Y=255.0±73.0X, r=0.99, p<0.001 ). N-SH (nonprotein sulfhydryl), P\|SH (protein sulfhydryl), T-SH (total sulfhydryl) contents and GSH\|Px activities decreased significantly (p<0.05-p<0.001). For GSH\|Px, both groups reached minimum value on the first poisoning day. In female rats, activities of SOD and XOD increased markedly ( p<0.02-p<0.01 ) although the contents of FR showed no significant changes. The contents of MeHg was determined by GC, and it ranged from 0.0081—0.0191 ppm. | LIU Jin\|yu 1, GUAN Ming 1, SUN Zhi\|wei 1, LIN Xiu\|wu 1, CAO Peng\|yuan 2, MENG Xiang\|dong 2 (1.
