SOMATOMAMMOTROPHS, FSH-LH AND ACTH-LH CELLS, THE BIHORMONAL CELLS IN BUFFALO PARS-DISTALIS ADENOHYPOPHYSIS

Using differential staining methods while hormone producing cells were demonstrated in the pars distalis adenohypophysis of 52 buffaloes of either ser: and aged I week to adult, the occurrence of bihormonal cel ls including the somaromammotrophs; FSH-LH and ACTH-LH cells was evide nced. They were relatively more frequent in older animals. Different t ypes of secretary granules within the same cell were either intermingl ed, or were intermixed in one of its part and localized single in the other part, or they were localized separately in its different parts. Their possible significance has been discussed.
