Radioimmunoassay for phencyclidine (PCP) in serum.

Radioimmunoassay for phencyclidine (PCP) in serum.

This accurate, sensitive radioimmunoassay for determining phencyclidine concentrations in serum specimens involves the use of anti-phencyclidine sera, 0.1 mL of serum specimen, an iodinated tracer, and a solid-phase separation. Phencyclidine metabolites do not show significant cross reactivity, but several phencyclidine analogs do cross react. Within-run coefficients of variation for human and ...

PCP Phencyclidine Abuse an Appraisal, 21

Gestational exposure to phencyclidine (PCP) in rats decreases PCP binding sites in term fetal brain.

Pregnant Sprague-Dawley rats were treated with 5 mg/kg body weight of phencyclidine (PCP) injected at 1 ml/kg subcutaneously on three consecutive days at four different stages of gestation. Within 10-30 min after treatment, dams showed some lack of motor coordination and became lethargic. On gestational day 21, all rats were killed by decapitation and brains were dissected and stored from mothe...

The convulsant and anticonvulsant effects of phencyclidine (PCP) and PCP analogues in the rat.

The pro- and anticonvulsant effects of phencyclidine (1-[1-phenylcyclohexyl]piperidine HCl, PCP), a number of its analogues, and SKF 10047 were investigated in rats. The PCP analogues were compounds produced by substitutions for the phenyl and piperidine rings of PCP and were selected to elucidate the structure-activity relationships existing between PCP and its pro- and/or anticonvulsant effec...

Discriminative stimulus properties of phencyclidine (PCP)-related compounds: correlations with 3H-PCP binding potency measured autoradiographically.

Several PCP analogs, the putative PCP agonist MDP, and the sigma receptor agonists SKF-10,047 and dexoxadrol were tested for their ability to substitute for PCP in animals trained to discriminate PCP from saline. The potencies of these compounds in substituting for PCP in the behavioral task correlated with their abilities to inhibit the specific binding of 3H-PCP to rat hippocampal sections me...
