Very few cases of parvovirus induced hepatic failure have been reported in adults and fewer still have required liver transplantation. We report the case of a 55-year-old immunocompetent woman who developed fulminant hepatic failure after acute infection with Parvovirus B19 who subsequently underwent orthotopic liver transplantation. This is believed to be the first reported case in the literature in which an adult patient with fulminant hepatic failure associated with acute parvovirus B19 infection and without hematologic abnormalities has been identified prior to undergoing liver transplantation. This case suggests that Parvovirus B19 induced liver disease can affect adults, can occur in the absence of hematologic abnormalities and can be severe enough to require liver transplantation.展开更多

The pilot test results showed that the effects of the metal contamination level of catalyst on the propylene yield,the coke yield,the LPG yield,the gasoline yield,the selectivity of low carbon olefins,and coke selectivity was significant,and that the influence of metal contamination level on the conversion and dry gas yield was minor.展开更多
