Functional significance of beta-galactosidase and beta-glucuronidase in lipid metabolism in the medulla oblongata and pons of hedgehog (Paraechinus micropus).
The study presented deals with histochemical mapping of GAL-A, GLUC-A, phospholipids and neutral lipids in the medulla oblongata and pons of hedgehog. Interesting features observed are: 1. The distribution of the enzymes can best be observed in preparations incubated at a pH-level of 4.95. 2. The distributive patterns of both glycosidases are exactly identical. Both enzymes are observed in myelinated nerve fibres, whereas their activity in nerve cells is either subdued or completely missing. The neuropil shows an appreciable amount of enzymes. 3. The distribution of phospholipids and neutral lipids parallels to that of glycosidases. These enzymes form the mirror image of the myelin preparations. The functional significance of the enzymes in relation to lipid metabolism is discussed.
