From: Downregulation of alpha7 nicotinic acetylcholine receptor in two-kidney one-clip hypertensive rats
Effects of atropine ( i.v., 0.03 mg/kg ) on heart rate in sham-operated rats and 2K1C hypertensive rats (n = 6). ΔHR, the difference of heart rate between pre-atropine and post-atropine injection. Atropine induced HR increase in sham-operated rats was significantly larger than in 2K1C group. *P < 0.05, **P < 0.01 vs age-matched sham-operated group (unpaired t test).
