1. The adenosine A1 receptor enhancer, PD 81,723, was tested for its neuroprotective activity in a Mongolian gerbil model of forebrain ischemia/reperfusion cerebral ischemia. 2. Gerbils were injected with PD 81,723 (1, 10 and 125 mg/kg i.p.) 20 min before a 5-min episode of forebrain ischemia. The extent of ischemic injury was assessed by monitoring the increases in locomotor activity and from the degree of damage to the CA1 hippocampal pyramidal cell layer after 5 days of recovery. 3. By both criteria, PD 81,723, at all three dose levels, failed to protect against ischemia/reperfusion evoked cerebral injury.

D002545	Brain Ischemia	Localized reduction of blood flow to brain tissue due to arterial obstruction or systemic hypoperfusion. This frequently occurs in conjunction with brain hypoxia (HYPOXIA, BRAIN). Prolonged ischemia is associated with BRAIN INFARCTION.

D005849	Gerbillinae	A subfamily of the Muridae consisting of several genera including Gerbillus, Rhombomys, Tatera, Meriones, and Psammomys.	Gerbils,Jird,Meriones,Psammomys,Rats, Sand,Gerbil,Jirds,Merione,Rat, Sand,Sand Rat,Sand Rats
D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.

D015427	Reperfusion Injury	Adverse functional, metabolic, or structural changes in tissues that result from the restoration of blood flow to the tissue (REPERFUSION) following ISCHEMIA.

D018047	Receptors, Purinergic P1	A class of cell surface receptors that prefer ADENOSINE to other endogenous PURINES. Purinergic P1 receptors are widespread in the body including the cardiovascular, respiratory, immune, and nervous systems. There are at least two pharmacologically distinguishable types (A1 and A2, or Ri and Ra).
