Table 1 Baseline mean arterial pressure (MAP) and heart rate (HR) of orchiectomized/testosterone (O/T), orchiectomized/vehicle (O/V), long-term castrated (L.T.C.), and sham-operated (SO) rats. The rats were allowed to acclimatize to laboratory conditions for at least 2 h prior to experimentation and a period of at least 30 min was allowed after connecting the rat to the pressure transducer for stabilization of blood pressure and heart rate. aP < 0.05 vs orchiectomized/vehicle.
Group | n | MAP (mmHg) | HR (beats/min) |
|---|---|---|---|
O/T | 21 | 108 ± 2.6 | 392 ± 6a |
O/V | 14 | 105 ± 1.7 | 427 ± 10 |
L.T.C. | 12 | 109 ± 4.1 | 414 ± 9 |
S.O. | 5 | 102 ± 1.8 | 421 ± 14 |
