Aluminum 62-70 glutamate-ammonia ligase Rattus norvegicus 31-51 10327419-4 1998 Both Fe and Al dosing elevated glutamine synthetase activity in the cortex. Aluminum 12-14 glutamate-ammonia ligase Rattus norvegicus 31-51 10501207-6 1999 Levels of a predominantly astroglial enzyme, glutamine synthetase, were also selectively reduced in the frontal cortex following intraventricular injection of aluminum. Aluminum 159-167 glutamate-ammonia ligase Rattus norvegicus 45-65
