Effect of insulin on serotonin, 5-hydroxyindole-acetic acid, norepinephrine, epinephrine and corticosterone contents in chick.

abstract：:The effects of the group III mGluR agonist, L-2-amino-4-phosphonobutyrate (L-AP4), on depolarization-stimulated cGMP levels in adult rat cerebellar slices were determined. L-AP4 elicited a concentration-dependent, complete inhibition of cGMP formation stimulated by 4-aminopyridine (4-AP; 1 mM), yielding an IC50 value ...
