A cross-sectional study was conducted among fish-processing workers to evaluate the prevalence of shoulder and upper-limb discomforts and to assess the associated ergonomic risk factors. A prestructured interview, a medical check-up, and job analyses were performed to determine musculoskeletal disorders among 207 workers in eight factories. The results(More)
The stems of Bougainvillea spectabillis Wild (Nyctaginaceae) have been used in folk medicine for hepatis, and spinasterol and quercetin were isolated and characterized from the plant leaves in this study. These constituents have not been previously isolated from Bougainvillea spectabillis W. Quercetin, the flavonoid, was found as active principle because it(More)
We have reviewed a single surgeon's experience with isolated talonavicular fusion in 16 patients with talonavicular arthritis. Fixation was either by staples or screws. Fifteen solid unions were achieved in the 16 patients who were followed (mean: 51 months). The average Ankle-Hindfoot Scale improved from 77.2 preoperatively to 92.9 postoperatively (p <(More)
The superoxide scavenging effects of fifteen coumarins were tested on the xanthine-xanthine oxidase-cytochrome C system. The results showed that fraxetin(10) displayed the strongest activity, and its percent inhibition at 100, 10 and 1 muM were 100, 100 and 53.13% respectively. Esculetin(4) showed the second strongest activity resulting in percent(More)
The immunomodulatory effects of Physalis angulata L. extract fraction VII (PA-VII), PA-VII-A, PA-VII-B and PA-VII-C were investigated in this study. The results showed that PA-VII and PA-VII-C strongly enhanced blastogenesis response, PA-VII-B had moderate activity, and PA-VII-A exerted only slight effect on cell proliferation. A synergistic effect was(More)
To explore whether the extremely low frequency (ELF) electromagnetic fields (EMFs) may act as cancer promoters or be synergistic with 12-O-tetradecanoylphorbol-13-acetate (TPA) in cancer promotion, an experiment was conducted on the effects of 50 Hz magnetic fields (MFs) on gap junctional intercellular communication (GJIC) of Chinese hamster lung (CHL)(More)
OBJECTIVE Plasma B-group vitamins and age may affect the carotid intima-media thickness (IMT) in subjects with different 677TT genotype of the methylenetetrahydrofolate reductase (MTHFR) gene. DESIGN A hospital-based cross-study. SETTING Genomic and Vascular Center, Changhua Christian Hospital, Changhua, Taiwan. SUBJECTS Five hundred and forty-one(More)
Five-thousand nine-hundred thirteen Taiwanese adults were selected by multistage sampling methods to investigate environmental lead exposure in Taiwan. The blood specimens were distributed to six laboratories for blood lead levels (BLL) measurement. The mean BLL of the 5913 Taiwanese adults was 8.28 +/- 5.39 microg/dl, with a maximum level of 57.6(More)
Crocetin, a major component of the fruit of Gardenia jasminoides Ellis, was investigated for its antitumor promoting effect on 12-O-tetradecanoylphorbol-13-acetate-promoted mouse skin carcinogenesis. Topical application of 5 nmol TPA to CD-1 mice once daily for 5 days caused epidermal hyperplasia, and increases in the levels of c-Fos, c-Jun and c-Myc in the(More)
The shipscrapping industry in Taiwan is located at Kaohsiung harbor. The scrapping yard at Kaohsiung can be divided into the "Da-Jen" area and the "Da-Lin" area, including 23 and 13 docks respectively. About 5000-8000 dock workers are employed in the yard. Because shipscrapping has been considered to be a "temporary" industry by the secondary metal dealers,(More)
