| Gelle test | A vibrating tuning fork is applied over the mastoid process; if it is heard, the air in the external auditory canal is compressed, by means of a rubber tube inserted into the canal and a hand bulb, thereby fixing the stapes in the oval window, and the sound ceases to be heard, but is again perceived if the air pressure is removed; a test of the mobility of the ossicles.

| Gell and Coombs c. |
a classification of immune mechanisms of tissue injury, called by Gell and Coombs “allergic reactions,” comprising four types: type I, immediate hypersensitivity reactions, mediated by IgE antibody; type II, antibody-mediated hypersensitivity reactions, including complement-dependent lysis, antibody-dependent cell-mediated cytotoxicity (ADCC), and phagocytosis induced by opsonizing antibody; type III, immune complex–mediated hypersensitivity reactions, including serum sickness, Arthus reactions, and systemic lupus erythematosus; and type IV, cell-mediated hypersensitivity reactions, mediated by sensitized T lymphocytes either by release of lymphokines or by T-cell–mediated cytotoxicity, including contact dermatitis, allograft rejection, and graft-versus-host disease. Other authorities have added type V, antibody interference with the function of biologically active substances, including autoimmune diseases mediated by antireceptor antibodies and coagulation disorders mediated by antibodies to coagulation factors. The individual types I–IV are described under hypersensitivity reaction, under reaction.
