Clinical findings and immunological abnormalities in Yu-Cheng patients.
An outbreak of poisoning caused by ingestion of rice bran oil which was accidentally contaminated with polychlorinated biphenyls (PCBs) broke out in Taiwan in February 1979. Diagnosis, management, and follow-up of the patients were performed at special clinics, and subjective symptoms and cutaneous changes such as peculiar acneform eruptions and pigmentation were recorded. The patients were div...
متن کاملPCBs, PCQs and PCDFs in tissues of yusho and yu-cheng patients.
All five samples of oil involved in the recent yu-cheng outbreak were heavily contaminated with PCBs, PCQs and PCDFs at levels, on the average, of 62, 20 and 0.14 ppm, respectively. The samples not only had roughly one-tenth of the contamination by PCBs, PCQs and PCDFs but also three to four times lower ratios of PCQs and PCDFs to PCBs than samples of oil involved in yusho in Japan. PCBs, PCQs ...
متن کاملBiological effect of PCBs, PCQs and PCDFs present in the oil causing yusho and yu-cheng.
Male Sprague-Dawley rats were daily given orally for 22 days a regimen consisting of polychlorinated biphenyls (PCBs), 1 mg/day; polychlorinated quaterphenyls (PCQs), 1 mg/day; polychlorinated dibenzofurans (PCDFs), 10 micrograms/day; or a mixture of PCBs, PCQs and PCDFs (Mix-1, 1 mg + 1 mg + 10 micrograms/day). Female Cynomolgus monkeys were daily administered PCBs (5 mg), PCQs (5 mg) or a mix...
متن کاملPCB and PCDF congeners in the blood and tissues of yusho and yu-cheng patients.
Polychlorinated biphenyl (PCB) poisonings occurred in western Japan, where it is called yusho, in 1968, and in central Taiwan, where it is called yu-cheng, in 1979. The average concentrations of PCBs in the adipose tissue, liver and blood of yusho patients and in the blood of yu-cheng patients were 1.9 ppm, 0.08 ppm, 6.7 ppb and 99 ppb, respectively. Seven PCB congeners, such as 2,4,5,3',4'-pen...
متن کاملPCBs, PCQs and PCDFs in blood of yusho and yu-cheng patients.
Individual blood samples obtained from yusho and yu-cheng patients who had been poisoned by ingesting contaminated cooking oils, from workers occupationally exposed to polychlorinated biphenyls (PCBs) and from unexposed individuals were analyzed for PCBs, polychlorinated quaterphenyls (PCQs) and polychlorinated dibenzofurans (PCDFs) by gas chromatography and mass spectrometry. PCBs were found i...
