Pemphigus vulgaris is an autoimmune blistering disorder in which both genetic and environmental factors, mainly drugs, are thought to play a part in its aetiopathogenesis. Although some drugs that contain thiol groups, such as D-penicillamine and captopril, and non-thiol drugs, such as cephalosporin, have been reported to trigger or induce pemphigus, there are no previous reports regarding the influence of quinolones in triggering this disease. Here we present a case of pemphigus possibly triggered by quinolones. 相似文献

黑柴胡中新三萜皂甙的结构鉴定 总被引:3,自引:0,他引:3
从黑柴胡(Bupleurum smithii Wolff)根中分离出10个化合物,均为首次由该植物中获得。其中二个新三萜皂甙,即柴胡皂甙k和l(saikosaponin k and l),其结构经紫外、红外、核磁共振氢谱,碳谱和质谱等波谱测定和解析,分别确定为3β,16β,23,28-四羟基齐墩果烷-11,13(18)-二烯-3-O-β-D-吡喃木糖基-(1→2)-β-D-吡喃葡萄糖基-(1→3)-β-D-吡喃呋糖甙和3β,16α,23,28,30-五羟基齐墩果烷-11,13(18)-二烯-3-O-β-D-吡喃葡萄糖基-(1→3)-β-D-吡喃呋糖甙。 相似文献

Four children with tyrosinaemia type 1 received liver transplants. The metabolic disorder was corrected and all four had normal liver function on an unrestricted diet. Two children, transplanted at age five and seven years, proved to have occult hepatocellular carcinoma and both subsequently developed pulmonary metastases. One child was well 32 months after removal of a single pulmonary metastasis but the other child died with multiple metastases. The two younger children, transplanted at age 19 and 21 months, were well 28 and 44 months after operation, one after a second liver transplant. Our experience confirms the high risk of hepatocellular carcinoma in this disease and the potential value of early liver transplantation. 相似文献

Inactivation of viral and prion pathogens by gamma-irradiation under conditions that maintain the integrity of human albumin 总被引:1,自引:0,他引:1

BACKGROUND AND OBJECTIVES: The administration of therapeutic plasma protein concentrates has been associated with the real risk of transmitting viral diseases and the theoretical risks of prion transmission. Our objective was to determine if gamma-irradiation can inactivate viral or prion infectivity without damaging a protein biotherapeutically. MATERIALS AND METHODS: Human albumin 25% solution, spiked with four model viruses (including porcine parvovirus) or with brain homogenate from scrapie-infected hamsters, was gamma-irradiated at constant low-dose rates and assayed for viral and prion infectivity or for albumin integrity. RESULTS: At a radiation dose of 50 kGy, viruses were inactivated by >/= 3.2 to >/= 6.4 log10 and scrapie by an estimated 1.5 log10, whereas albumin was only moderately aggregated and fragmented. CONCLUSIONS: gamma-Irradiation can preferentially inactivate viral and prion pathogens without excessive damage to albumin structure. 相似文献

One hundred and seventy three children, including 93 with biliary atresia, received liver grafts at Addenbrooke's Hospital between 1983 and 1993. Of these, only seven developed cyanosis due to intrapulmonary shunting as a complication of their liver disease, and all seven of these had the biliary atresia/polysplenia syndrome. Intrapulmonary shunting was confirmed by a radioisotope scan in four children. Only one child with the syndrome did not have cyanosis when undergoing transplantation. Seven of the eight children are alive 6-54 months after transplantation, with normal pulmonary and hepatic function. Cyanosis recurred in one child who developed chronic rejection with liver failure. In conclusion: (a) there is a strong association between the biliary atresia/polysplenia syndrome and cyanosis due to intrapulmonary shunting; (b) intrapulmonary shunting is fully reversible after successful liver transplantation; and (c) cyanosis, once present, is progressive, and these children should be considered for liver transplantation as soon as it occurs. 相似文献
