Brown alga, Turbinaria conoides was successively extracted with n-hexane, cyclohexane, methanol and ethanol:water (1:1). The extracts were evaluated for antibacterial and antifungal activities by disc diffusion method. Minimal inhibitory concentration was determined for active extracts by broth dilution method. The antiviral activity and cytotoxicity of the extracts were tested in human embryon...

We read with great interest the report by Murray et al.' We have analyzed 3 1 posttransplantation lymphoproliferative disorders (PTLDs; 18 renal and 13 heartheart-lung cases) for bcl-2, EpsteinBarr virus-latent membrane protein (EBV-LMP), EBNA-l, and EBNA-2.2.5 We used the same antibodies as Murray et al.' All cases were EBV-LMP-l -positive. In more than 90% of cases, 80% of the neoplastic popu...

Hemophagocytic lymphohistiocytosis (HLH) can be divided into primary (genetic or familial) and secondary (acquired or reactive) forms. Abnormal immunophenotyping and downregulation of CD5 or CD7 in T cells have been well characterized in EpsteinBarr virus (EBV)-associated HLH [1, 2]. A few studies have also reported abnormal immunophenotyping of T cells in patients with familial HLH (FHL) [1, 3...

The enigma of Hodgkin's disease etiology has fascinated several generations of researchers. Of particular scientific interest has been the hypothesis that Hodgkin's disease might have an infectious etiology. The paper by Mueller in this issue chronicles the development of the important work of two generations of investigators (herself and Dr. Alfred S. Evans) trying to explicate the role of vir...

results: of 655 samples, 69 (10.53%) had positive results for human influenza a virus, and 5 (0.7%) samples had positive results for influenza b. of those 69 samples with positive results for influenza a viruses, 45 (6.8%) were h3n2, and 24 (3.6%) were h1n1 subtypes. in this study most cases with positive results were less than 20 years. the sample positive included 49% males and 51% females. t...

Progressively more potent immunosuppressive medications have significantly reduced the incidence of rejection of solid and bone marrow transplants while increasing patients’ susceptibility to potentially opportunistic infections (1). This study reports a mixed infection in a renal transplant patient because of herpes simplex virus (HSV) and Sarcoptes scabiei. A 34-year-old male renal transplant...
