Non-tropical pyomyositis in adults: Report of four cases and literature review

Four cases of non-tropical pyomyositis in adults are presented and 72 cases reported in the literature are reviewed. The diagnosis is often overlooked or delayed because most physicians are not familiar with the entity. Local signs of inflammation, fever, leukocytosis and an elevated erythrocyte sedimentation rate are common features.Staphylococcus aureus is the most common pathogen and the thigh muscles are the most common site involved. Computerized tomography is used to establish the diagnosis and surgical incision and drainage in combination with antibiotic therapy is successful in the majority of the cases.     

毛茛甙的抗诱变作用及代谢转化

研究表明,毛茛甙可显著抑制MMC和MMS等诱变剂对沙门氏菌TA_(100)和TA_(102)回复突变作用;对MMC诱发的小鼠PEC徽核抑制率达56.5%。代谢研究表明:毛茛甙抑制DNA生物合成的作用可被肝微粒体酶和胞浆液分别降低46和12%;RP-HPLC测定显示,体外毛茛甙可被肝微粒代谢转化。     

Digital radiography.Results of a survey (part A) and a consensus conference (part B)

Digital imaging (digital image intensifier radiography, storage phosphor/selenium radiography) is increasingly becoming commonplace in radiology departments for diagnostic purposes. Despite 10 years of experience, the advantages and disadvantages of those methods are still heavily discussed among users, financiers and prescribers. This paper is to offer additional arguments for a thorough and objective discussion. No further comments or interpretations have been added to this paper. This paper consists of two main parts, A and B. The first part deals with the results of a user survey, the other part presents the results, i. e. statements, of a consensus conference.
