Histological and histoenzymological studies of medulla oblongata of Taphozous melanopogon Temminck (a Microchiroptera).

The paper deals with the histological and histoenzymological studies of the medulla oblongata of Taphozous melanopogon Temminck (a microchiropteran bat). Three phosphatases, namely acid phosphatase (ACP), thiamine pyrophosphatase (TTP) and glucose-6-phosphatase (G-6-P) were studied. All the enzymes were seen in all the neurons. The large neurons of the different nuclei are more strongly positive for ACP than the small neurons. Further, the areas which contain dense populations of neurons are more strongly stained than the area containing scattered neurons. TPP and G-6-P distributions are almost parallel to that of ACP. The functions of these enzymes in synthesis and secretory processes were discussed.
