“ Carbachol also increased the spontaneous frequency of contraction and these rate responses were again inhibited by DEANO and nitroprusside, but unaffected by L-NNA.”
“Maximum tonic contractions to carbachol were reduced by 17 ± 4% (P<0.001) and 35 ± 5% (P<0.001) by DEANO and nitroprusside respectively and the potency of carbachol was also reduced.”
