Figure 7. Effects of N-acetylcysteine (NAC) on the neurosecretory response elicited by high external K+ in chemoreceptor cells of the CB.
Experimental protocol was as given in Fig. 5. S2/S1 ratios in control and NAC-treated calf (A) and rabbit (B) CBs refer to two sequential stimulations with high external K+ (incubation with 35 mm K+ for 10 min). Data are means ± s.e.m. of 10 individual values for the calf CBs and 7 individual values for the rabbit CBs. The differences between control and NAC-treated organs are not statistically significant.
