Malignant melanoma metastatic to the gingiva has been reported only once. We present a case in which the occurrence of melanoma in the gingiva followed extraction of a periapically "abscessed" tooth. Since the initial periapical mass may well have been a metastatic tumor, particularly in a patient undergoing therapy for disseminated malignant disease, the(More)
Presence of human immunodeficiency virus (HIV) within noninflamed human dental pulps was documented by polymerase chain reaction assays in 11 of 12 pulps from HIV-seropositive patients. The purpose of the present study was to determine the cellular location of HIV in vivo within these tissues by means of in situ hybridization. Results of the in situ(More)
The first objective of the experiment was to demonstrate that murine spleen cells treated with the T cell mitogen phytohemagglutinin induced neovascularization when adoptively transferred to the chorioallantoic membrane of chicken eggs. The second objective was to show that neovascularization could be induced by the supernatants from these cultures. The(More)
Tumor growth was measured in inbred (C3H and C3Hf) and hybrid (C3H X C57BL/6F1 and BALB/c X C3HF1) mice after partial hepatectomy, sham hepatectomy, and hind limb amputation. Epithelial tumors (mammary carcinoma) and mesenchymal tumors (methylcholanthrene-induced and spontaneous tissue culture) were used in order to determine the tissue specificity of the(More)
The hypothesis tested was that tumor-specific transplantation antigens of chemically induced tumors cross-react with allogeneic histocompatibility antigens. This hypothesis makes several predictions that can be tested experimentally. First, tumors should grow better and be less immunogenic in certain F1 hybrids than in their syngeneic parents, owing to the(More)
