Effect of whole pituitary extract on the corpuscles of stannius in Notopterus notopterus (Pallas).
Administration of pituitary extract brings important change in the cells of the corpuscles of stannius. Two variety of cells are found in the corpuscles of stannius of control group, one with dense cytoplasm while the other possess non-reactive cytoplasm. Under the influence of whole pituitary extract, there is an intense cell activity in corpuscles of stannius suggesting more synthesis of hypocalcemic factor. Other possible reasons like stimulation of interrenal, thereby activating corpuscles of stannius have also been discussed. The possible involvement of ACTH or cortisol and synergistic effect of prolactin in promotion of hypercalcemia have also been suggested.
