The effects of HC-030031 pretreatment on the potentiation of capsaicin (Cap)-evoked Ca²⁺ transients by NaHS (200 μM, 2.5 min) in CSLV neurons. A: without HC-030031 pretreatment (20 μM, 16.5 min) in nodose (n = 18) and jugular (n = 24) ganglion neurons. B: pretreatment with HC-030031 in nodose (n = 22) and jugular (n = 18) ganglion neurons. See Fig. 7 for further explanation. An increase in intracellular Ca²⁺ concentration (Δ[Ca²⁺]_i) was measured as the difference between the peak amplitude of Ca²⁺ transients (4-s average) and the 30-s average at baseline. ^aSignificantly different from the value of Cap only (P < 0.05). Data in each group are means ± SE.
