The presentation and management of 10 cases of proven or presumptive fungal endophthalmitis in narcotic-drug abusers is described. Miconazole was found to be an effective agent in some patients when administered in a dosage of 2400 mg/day. Eight patients received treatment with a combination of miconazole and flucytosine (5-fluorocytosine). Regression of the infection with preservation of the eye was observed in each case. However, visual acuity in the affected eye improved only in four of the eight patients; it was unchanged in two and had deteriorated in the other two. In two patients, who received amphotericin B and flucytosine as initial treatment, control of the infection was achieved, but vision remained unchanged. Vitrectomy was performed in three patients to remove residual sites of infection. However, vision remained unchanged in two of these patients and worsened in the third. The selection of individual modalities of therapy and responses to treatment are discussed.

Experimental model for scleritis.

Rabbits were sensitized over a prolonged period to ovalbumin by intradermal injection. Ovalbumin was then injected into the limbus of the eye. A corneoscleral lesion, similar to necrotizing scleritis in humans, was produced. The clinical progression of the lesion is described and its histologic appearance discussed in relation to the human disease.

Identification of the gene for a Plasmodium yoelii rhoptry protein. Multiple copies in the parasite genome.

Serum from mice hyperimmune to Plasmodium yoelii was used to screen a P. yoelii genomic DNA library. Antibodies selected from hyperimmune serum by lambda gt11 clone J7 or raised against a specific fusion protein or peptide produced a punctate pattern of immunofluorescence on fixed smears of parasitised erythrocytes and immunoprecipitated a 235-kDa protein apparently identical to a rhoptry protein previously implicated in red cell invasion. The cloned DNA hybridised to at least seven RsaI fragments of P. yoelii genomic DNA and to three DraI fragments of similar but not identical sequence. These results suggest that the gene encoding the 235-kDa rhoptry protein may be represented more than once in the P. yoelii genome.
