  • Title: The effect of lymphocytes from sufferers from recurrent aphthous ulceration upon colon cells in tissue culture.
    Author: Dolby AE.
    Journal: Gut; 1972 May; 13(5):387-9. PubMed ID: 5036095.
    Abstract:
    The release of (51)Cr from labelled colon cells was used to assess a possible lymphocytotoxic effect of peripheral blood lymphocytes from patients suffering from recurrent aphthous ulceration. No significant (p > 0.03) difference was observed between the isotope release following incubation with patients' or control lymphocytes. The absence of such a lymphocytotoxic effect, detectable with oral epithelial cells, is discussed in relation to the role of cellular hypersensitivity in the pathogenesis of ulcerative colitis and aphthous ulceration.
