title: Seasonal changes in the histoenzymatic distribution of acid and alkaline phosphatases activity in the B cells of the thoracic ganglion of fresh-water crab, Potamon magnum magnum (Pretzman).
abstract: The present study deals with acid and alkaline phosphatases activity determination in B cells of the thoracie ganglion of Potamon magnum magnum. Intense alkaline and acid phosphatases activity is seen in the neurosecretory granules as well as in the neural sheath. Acid phosphatase activity unlike alkaline phosphatase distribution, is seen in form of positive stained spherules showing different pattern of distribution. Alkaline phosphatase activity is linked with the metabolic process. The significance of these results is discussed.
