Effects of microinjection of Ang II or losartan into the RVLM on local release of amino acids.

*P<0.05 compared with the ACSF group at the same time point; ΔP<0.05 compared with baseline (10 min prior to microinjection); #P<0.05 compared with the normotensive rats at the same time point. Amino acids (AA) were measured at baseline, 1st, 2nd, 3rd 10 min after administration of ACSF, Ang II or losartan, respectively (n = 8 in each group). Asp, aspartate; Glu, Glutamate; Gly, Glycine; Tau, taurine; GABA, γ-aminobutyric acid.
