Abstract：
:The effect of postnatal administration of phenobarbital on enzymes degrading enkephalin was examined. Daily subcutaneous injections (45 mg/kg) of phenobarbital were given to male and female rats from postnatal day 1 to 19. Brains from rats treated with saline and phenobarbital were used to prepare aminopeptidases (high speed supernatant) and enkephalinase A (synaptosomal membrane preparation). Incubation of methionine enkephaline (ME) with aminopeptidases from rat brain liberated tyrosine (T), while incubating with enkephalinase A resulted in the formation of tyrosylglycylglycin (TGG). Separation and quantification of tyrosine, tyrosylglycylglycin and methionine enkephalin was performed using a high performance liquid chromatograph, coupled to electrochemical and ultraviolet detectors in series. The treatment of the rats with phenobarbital resulted in a significant inhibition of enkephalinase A when measured in vitro, using methionine enkephalin as substrate. Preliminary studies with secobarbital show similar results to those obtained with phenobarbital.

There are eight mammalian P2Y receptor subtypes (P2Y1, P2Y2, P2Y4, P2Y6, P2Y11, P2Y12, P2Y13, and P2Y14). P2Y receptors are widely expressed and play important roles in physiology and pathophysiology. One important example is the ADP-...
