Four case reports are presented of patients who ate the meat of a hog inadvertently fed seed treated with fungicides containing ethyl mercury chloride. The clinical, electrophysiological, and toxicological, and in two of the patients the pathological data, showed that this organic mercury compound has a very high toxicity not only for the brain, but also for the spinal motoneurones, peripheral nerves, skeletal muscles, and myocardium. 相似文献

In leukopenic mice with severe systemic candidiasis, single-dose treatment (5 mg of amphotericin B [AMB]/kg of body weight) with long-circulating polyethylene glycol-coated AMB liposomes (PEG-AMB-LIP) resulted in zero mortality and a significant reduction in the number of viable Candida albicans in the kidney, whereas 70% mortality was seen in mice treated with five daily doses of AmBisome (5 mg of AMB/kg . day). When the first of five daily doses of AmBisome was combined with a single low dose of Fungizone (0.1 mg of AMB/kg), the efficacy was equal to that of PEG-AMB-LIP. 相似文献

AIM: The study of possibility of reappearance of malaria foci in the Donets region. MATERIALS AND METHODS: 322 cases of imported malaria (IM) in the Donets region registered in 1979-1997 have been analysed clinically and epidemiologically. Malaria was diagnosed in immigrants from and visitors to Africa, Asia and Latin America, malaria-endemic Azerbaidjan, Tadzhikistan, Afghanistan. RESULTS: Late diagnosis of malaria occurred in immigrants and businessmen who got infected during their business trips. Causative agents of malaria imported from Azerbaijan and Asia were resistant to chemoprophylaxis with delagil and primaxine. Clinical forms of IM are described. CONCLUSION: There is a real danger of malaria reappearance in the Donetsk region as the residents are at risk of being infected from late-diagnosis foreign tourists, immigrants, refugees. 相似文献
