To determine the feasibility of en bloc removal of the heart, lungs, liver, kidneys, and pancreas for preservation with warm blood autoperfusion, organs from 34 dogs were preserved ex vivo for periods of between 3 and 22 hours. The lungs were ventilated with a Bird Mark 7 respirator, and the heart served as the pump to perfuse all organs of the multiple(More)

We have studied the potential use of immunotoxins (ITs) for therapeutic treatment of human tumors in an experimental model of human neoplasia. We tested intact ricin IT for its antitumor activity against established tumors. CEM, a human T-cell leukemia line expressing an Mr 67,000 cell surface antigen, and Daudi, a human B-cell lymphoma line which does not(More)
Dihydroxyacetone and lawsone, in a vanishing cream base, applied to the skin was found to protect patients with erythropoietic protoporphyria against sunlight. The use of the same ingredients in a 50% isopropyl alcohol/water solution did not induce adequate light protection. The chemically induced ultraviolet light filter in the stratum corneum allowed(More)
The increasingly broad application of electron microscopy to the study of cytological detail in both normal and pathological tissues has created a need for an improved staining method for light microscopy of material processed primarily for electron optical investigation. A staining technic that would produce results comparable to those obtained with(More)
