To further elucidate the extent of variation among Pneumocystis carinii obtained from different mammalian hosts, polymerase chain reaction (PCR) analysis of the genes encoding two antigens of P. carinii was done. Using primers based on the ferret P. carinii glycoprotein (gp)A gene and the rat P. carinii 45- to 55-kDa antigen gene, amplification was(More)
Photodynamic therapy consists of the systemic administration of a derivative of haematoporphyrin (Photofrin II) followed 24-72 h later by exposure of malignant lesions to photoradiation. We investigated the efficacy of this treatment after direct intratumoral injection of Photofrin II. This direct treatment regimen resulted in higher rates of inhibition of(More)
