IMAGES-2

fig. 6
Figure 6. Effects of ethanol 25 mM, 50 mM and 100 mM on basal specific alanine aminopeptidase activity in mouse frontal cortex synaptosomes (A) or after the stimulation with K+ 25 mM (B). Results are expressed in nmol of alanine-ß-naphthylamide hydrolized per min and mg of protein (Mean±SEM; n=11; **p<0.01).

 

fig. 7
Figure 7. Effects of ethanol 25 mM, 50 mM and 100 mM on basal specific arginine aminopeptidase activity in mouse frontal cortex synaptosomes (A) or after the stimulation with K+ 25 mM (B). Results are expressed in nmol of arginine-ß-naphthylamide hydrolized per min and mg of protein (Mean±SEM; n=11; **p<0.01).

 

fig. 8
Figure 8. Effects of ethanol 25 mM, 50 mM and 100 mM on basal specific cystine aminopeptidase activity in mouse frontal cortex synaptosomes (A) or after the stimulation with K+ 25 mM (B). Results are expressed in nmol of cystine-ß-naphthylamide hydrolized per min and mg of protein (Mean±SEM; n=11; **p<0.01).

 

fig. 9
Figure 9. Effects of ethanol 25 mM, 50 mM and 100 mM on basal specific leucine aminopeptidase activity in mouse frontal cortex synaptosomes (A) or after the stimulation with K+ 25 mM (B). Results are expressed in nmol of leucine-ß-naphthylamide hydrolized per min and mg of protein (Mean±SEM; n=11; **p<0.01).

 

fig. 10
Figure 10. Effects of ethanol 25 mM, 50 mM and 100 mM on basal specific tyrosine aminopeptidase activity in mouse frontal cortex synaptosomes (A) or after the stimulation with K+ 25 mM (B). Results are expressed in nmol of tyrosine-ß-naphthylamide hydrolized per min and mg of protein (Mean±SEM; n=11; **p<0.01).
