Glutamine synthetase activity and glutamate uptake in hippocampus and frontal cortex in portal hypertensive rats

Figure 1 GS activity in the hippocampus and FC. Values are the mean ± SE in eight experiments. ^bP < 0.01 compared with respective control group. HIC: Hippocampus.

Figure 2 Time course of [³H] L-glutamate uptake in FC and hippocampus. Synaptosomes were incubated with [³H] L-glutamate at 10 nmol/L substrate concentration, for > 30 min, in the presence of 125 mmol/L NaCl at 30°C. Values are the mean ± SE in six or seven separate experiments done in triplicate. ^aP < 0.05; ^bP < 0.01 compared with respective control group. C: Control group; PH: Portal hypertension group.
