Physiologic parameters in animals undergoing BOLD experiments
Group | pH | Pco2 (mm Hg) | Pao2 (mm Hg) | MABP (mm Hg)* |
---|---|---|---|---|
Systemic saline, control animals (n = 4) | ||||
Preinjection | 7.42 ± 0.03 | 36 ± 1.6 | 152 ± 29 | 100 ± 8 |
Postinjection | 7.41 ± 0.04 | 37 ± 4.9 | 126 ± 38 | 96 ± 12 |
Systemic theophylline, test animals (n = 5) | ||||
Preinjection | 7.40 ± 0.04 | 36 ± 1.9 | 157 ± 27 | 106 ± 7 |
Postinjection | 7.38 ± 0.02 | 37 ± 2.1 | 166 ± 11 | 106 ± 10 |
Note.—Postinjection values were recorded approximately 90 minutes after systemic injection. Pre- and post-injection values of the parameters did not differ significantly in either the test group or control group (P = 0.5, t test). The groups did not differ significantly (P = .05, t test).
* MABP indicates mean arterial blood pressure.
