CBS inhibition aggravates long-term impairment of postictal cerebral vasodilator functions. Seizures were induced by bicuculline (3 mg/kg, i.p.) The responses of pial arterioles to topical endothelium- and astrocyte-dependent vasodilators bradykinin (BK, 10−6 M), glutamate (Glu, 10−4 M), and ADP (10−4 M) were evaluated in intact pigs and in the 48 h postictal pigs (Seizures) that were untreated (Ctrl) or treated with either the CBS inhibitor AOA (5 mg/kg, i.p.) or the CSE inhibitor PPG (5 mg/kg, i.p.) (N = 5 per group). Values are means ± SD. *P < 0.05 compared with the baseline (Base). †P < 0.05 compared with the corresponding responses in the intact group.
