The effect of high-dose xylazine anaesthesia on Asp neurotransmitters in rat brain. C – control group, I – induction period, A – anaesthesia period, R1 – recovery period (group R1), R2 – recovery period ( group R2), R3 – recovery period (group R3). ∗P < 0.05; ∗∗P < 0.01
Fig. 5
Effects of different concentrations of xylazine on neurons secreting the neurotransmitter Gly. At 5, 10, 15, 20, 25, 30, 45, 60, 90, and 120 min xylazine was allowed to act on the neurons. (A) 15 μg/mL xylazine, (B) 25 μg/mL xylazine, (C) 35 μg/mL xylazine, (D) 45 μg/mL xylazine. ∗P < 0.05; ∗∗P < 0.01 versus control, #P < 0.05; ##P < 0.01 versus the minimum value
