Cryptococcal infection has been increasing among immunosuppressed population. We report three cases of Cryptococcus neoformans infection in immunosuppressed patients - two renal transplanted and one with lupus nephritis. Early infection (<3months) was diagnosed in two - an allograft Cryptococcus infection and a central nervous system involvement. The third, a 10-year transplant vintage patient,...

Xenografts from eight human bronchial carcinomas have been established in CBA/Lac mice rendered immunodeficient by neonatal thymectomy followed three weeks later by whole body irradiation (7.35 Gy (735 rads)) after a priming dose of cytosine arabinoside. Growth rates of individual tumour lines remain constant and the histological and chromosomal characteristics of the original tumour are mainta...

Immunosuppression with cyclosporin A or cyclophosphamide had no apparent effect on the disease course of guinea pigs infected with a virulent strain of Junin virus. Immunosuppression of guinea pigs infected with an attenuated strain of Junin virus led to fulminating Argentine hemorrhagic fever. All immunosuppressed infected animals died. Virus distribution patterns in target organs, as determin...

Hyperammonemia syndrome is an often fatal complication of lung transplantation which has been recently associated with Ureaplasma infection. It has not been definitely established that Ureaplasma species can cause hyperammonemia. We established a novel immunocompromised murine model of Ureaplasma urealyticum infection and used it to confirm that U. urealyticum can cause hyperammonemia. Male C3H...

BACKGROUND The immune response to adenoviral vectors used in gene transfer limits the duration of transgene expression and thus poses a potential limitation to their effectiveness for gene therapy. The need for immunosuppression in transplantation may modify this immune response and facilitate prolonged transgene expression. This study hypothesizes that in the setting of heart transplantation, ...

This study was conducted to evaluate the efficacy of oral administration of fenbendazole (20 mg/kg body weight) prior to and after experimental infection of immunosuppressed rabbits with Encephalitozoon cuniculi. A total of thirty rabbits were divided into five groups: NN (non-immunosuppressed; non-infected), IN (immunosuppressed; non-infected), IPI (immunosuppressed; protected-infected), ITI (...
