Abstract

Two autologous and 4 allogeneic conjunctival grafts have been transplanted to the corneal-scleral region in 6 dogs. The animals with the autografts and 2 of the allografts were untreated, while the animals with the other 2 allografts were treated with azathioprine and prednisolone. The grafts were followed with daily sequential, still photographic recording of the spreading of the fluorescence over the graft surfaces after fluorescein sodium had been given intravenously. A motordriven camera, with automatically timed exposures at very short intervals down to 1 sec, was used in combination with a fast recycling flash unit. The behaviour of the circulation seemed to be the same in auto- and in allografts during the first 8 days of healing. One day before showing signs of rejection at oridinary inspection, the two untreated allografts, on photographic analysis of the spreading of fluorescence, showed minute areas of non-fluorescence in an early stage of the procedure. The same type of local impairment of the circulation, manifested by slower uptake of dye in limited areas, was noted in the treated allografts, appearing 2-3 days before severe signs of rejection were noted at orinary inspection. These areas, however, gradually fille...Continue Reading

Allogenic & Autologous Therapies

Allogenic therapies are generated in large batches from unrelated donor tissues such as bone marrow. In contrast, autologous therapies are manufactures as a single lot from the patient being treated. Here is the latest research on allogenic and autologous therapies.
