In untreated WT vessels, the changes in EDD, tone, frequency, and FPF have been significantly various in the baseline for the three highest doses of ACh.When the identical WT vessels had been then treated with (Fig. 7A , open circles), the responses of EDD, tone, FREQ, and FPF to ACh had been abolished totally.

This discrepancy probably arises in the fact that the effects of L-NAME elevated constantly overtime, and that the ACh dose esponse was performed after 1 h of L-NAME therapy, although the pressure step data were obtained right after only 20 min of L-NAME therapy.25952-53-8 site A15 Change in EDD ( )EDDB5 Change in Tone ( ) 0 -5 -10 -Tone10 5 0 -5 0 10-9 10-8 10-7 10-6 [Acetylcholine], (M)10-10-10-10-[Acetylcholine], (M)C100 Normalized Amplitude 80 60 40 200 10-nAMPD1.PMID:33580389 0 Ejection Fraction ( ) 0.eight 0.six 0.four 0.2 0.10-EF**10-10-10-10-10-10-[Acetylcholine], (M)[Acetylcholine], (M)E150 Normalized FrequencynFREQFractional Pump Flow (min-1)*FFPF eNOS-/6 4 2L-NAME0 10-9 10-8 10-7 10-10-10-10-10-[Acetylcholine], (M)[Acetylcholine], (M)Figure 8.
