A sensitive method of 32P-postlabeling was used to determine DNA-styrene oxide adducts in lymphocytes from workers oecupation-lly exposed to styrene. Six DNA-styrene oxide adducts and deriva-ties were determined in four samples from workers occupationlly exposed to high concentration of styrene (>40ppm) and no adduct was detected in other 26 samples from workers occupationlly exposed to lower concentration of styrene and the controls. The total level of modification in lymphocytes from workers exposed to styrene...

A sensitive method of 32P-postlabeling was used to determine DNA-styrene oxide adducts in lymphocytes from workers oecupation-lly exposed to styrene. Six DNA-styrene oxide adducts and deriva-ties were determined in four samples from workers occupationlly exposed to high concentration of styrene (>40ppm) and no adduct was detected in other 26 samples from workers occupationlly exposed to lower concentration of styrene and the controls. The total level of modification in lymphocytes from workers exposed to styrene was (5-9)XXX10-7 adducts/normal nucleotides.The number and position of DNA-styrene oxide adducts on the autoradiogram examined by 82P-postlabeling in lymphocytes were similar to the retults detected in samples interacted DNA and dGmP with styrene oxide in vitro. The structures of three adducts determined by 32P-postlabeling were identificated to be O6-(2-hydroxy-2-phenylethyl)-2-deoxyguanosine 3'-phosphate, O6-(2-hydroxy-1-phe-nylethyl)-2'-deoxyguanosine-3'-phosphate and N2-(2-hydroxy-l-phe-nylethyl)-2'-deoxyguanosine-3' -phosphate.Further sdudies are required for identifiying other adducts.

25 cases ill with essential hepertension (EH) were studied using enzyme linked immunosorbent assay (ELISA) to determine the index reflecting the damage of vascular endotheliocytes (VEC) in the plasma-factor Ⅷ related antigen and using thiobarbituric acid as say to determiine lipid peroxide reflecting the damage level of oxygen free radical in the plasme. The results showed that the concentrations of both the fartor Ⅷ related antigen and the lipid peroxide in the plasma of the patients ill with essential hepertension were significantly higher than those in normal control group(P<0. 05) and there was significantly positive correlation between the factor Ⅷ related antigen and the lipid peroxide (P<0. 05). The data mentioned above indicate that there is the damage of vascular endotheliocytes in the patients ill with essential hypertension and one of the important factors that leads to the damage of vascular endotheliocytes is oxygen free redical.
