unexposed
1.In photography, removing fixer and unexposed silver salts from photographic film and papers.
3.In an unexposed light-sensitive emulsion or coating, the slow chemical change that occurs when the material is stored in an unlighted area.
4.VC、FVC 、FEV_(1.0) and FEV_(1.0)% were significantly lower in the 238 welders than those in the control group made up of 506 unexposed electricians(P<0.01).
5.Odds ratios for washing raw lamb meat increased from 1.0 for unexposed villagers to 13.0 for villagers with exposure almost every day(X~2=10.95 ,P＜0.05).
6.The present study were to explore the neurotoxic effects of aluminum on exposed workers and to search for early monitoring index of Al induced neurotoxic effects. Neurobehavioral functions of 36 Al exposed and 40 unexposed workers were assessed using Neurobehavioral Core Test Battery (NCTB) recommended by WHO/NIOSH.
7.The mean weights of liver and kidney were significantly different between exposed rats and unexposed rats. Pathological examinations showed that hyalinosis of hepatic cell,epithelial cell degeneration and protein cast of proximal convoluted tubule were induced by MTBE UG.
8.Methods A computerized Neurobehavioral Evaluation System Chinese 3(NES C 3)was employed to 70 male Dacron workers as the exposure group and to 70 workers unexposed to any toxicants as the control group with age and education match.
9.Methods Workers in plastic industry were divided based on their exposure level,85 exposed to VC in workshop at a concentration lower than maximal allowable concentration (MAC) set in the national standards as a low-level group,75 exposed to VC higher than MAC as high level group,and 100 unexposed as healthy control group. DNA damage in lymphocytes was determined with single cell microgel electrophoresis and micronucleus test.
10.Methods Differentiation of NSCs,exposed or unexposed to ELF|EMF,was induced by CNTF or IL|1α at different concentration for 5 days. Cells then were fixed and processed for immunofluorescent staining to detect the neuron|specific marker,microtubule|associated protein 2ab(MAP2ab),thus the percentage of MAP2ab++ cells was calculated.
