Double IF on baboom unfixed diencephalon. a Pattern produced by a serum of a patient with diabetes insipidus: some cells of the diencephalon are stained. (from Ref. [1], p. 207, Fig. 7.7). b1 The serum of this patient counterstained by a goat anti-human FITC serum produced a green pattern concentrated in the cytoplasm of some cells. (from Ref. [1], p. 207, Fig. 7.8). b2 A rabbit serum anti-vasopressin counterstained with an anti-rabbit rhodaminated serum stains in red the same cells stained by the patient’s serum. b3 The double microphotographic exposure of the imaging a and b, produced a yellow colour (sum of green and red) of the cytoplasm of the cells confirming that the human serum reacts against vasopressin-producing cells
