title: Levels of glutamic acid decarboxylase (GAD), gamma amino butyric acid transaminase (GABA-T), glutamic acid dehydrogenase (GLDH) and proteins in cerebrospinal fluid of certain neurological disorders.
abstract: Important glutamic acid metabolising enzymes in brain namely GAD, GABA-A and GLDH have been studied in the CSF of tuberculous meningitis (TBM), pyogenic meningitis (PM) and brain tumor (BT). The levels of GAD were reported as picomoles of GABA formed/mg of protein/hour. The control levels of the enzymes were GAD = 129 +/- 54, GABA-T = 533 +/- 146 and GLDH...O. 198 +/- 0.097. The levels of GAD were significantly increased (P < 0.001), in both TBM and PM, the values were 302 +/- 81 and, 290 +/- 97 respectively. The GABA-T levels were significantly raised (P < 0.001) only in PM cases 639 +/- 171. The values were reported as nano moles of GABA transformed/mg of protein/hour. The CSF-GLDH levels (unit/litre) showed significant elevation (P +/- 0.001) in TBM in PM, the values were 0.41 +/- 0.1 and 0.41 +/- 0.18 respectively. The CSF proteins were markedly elevated in all the conditions.
