Temporal effect of acupuncture on amino acid neurotransmitters in rats with acute cerebral ischaemia.

Background: Acupuncture stimulation at GV26 during the acute phase of cerebral ischaemia can effectively reduce brain damage induced by ischaemic injury. However, the time course of the effects of acupuncture stimulation has not yet been thoroughly studied.

Objective: To investigate the effects of manual acupuncture (MA) on glutamic acid (Glu) and γ-aminobutyric acid (GABA) expression in the cerebrospinal fluid of rats with middle cerebral artery occlusion (MCAO) and determine whether there is a temporal effect of acupuncture on the treatment of cerebral ischaemia.

In the title compound, {[Pr(2)(C(2)O(4))(3)(H(2)O)(4)]·2H(2)O}(n), the three-dimensional network structure has the Pr(III) ion coordinated by nine O atoms in a distorted tricapped trigonal-prismatic geometry. The coordinated and uncoordinated water mol-ecules inter-act with the carboxyl-ate O atoms to consolidate the network via O-H⋯O hydrogen bonds.
