Figure 5

Histogram comparing relaxations to 10 μM ACh in aortic rings from control animals (n=5) and animals exposed 9 days earlier to 6 Gy radiation (n=5), in the absence of any drug (open bars) and in the presence of 5 μM indomethacin (indo), indomethacin plus 300 μM L-NA, indomethacin plus 10−8 M charybdotoxin (CTX) and 10−6 M apamin and indomethacin plus 300 μM L-NA plus 10−8 M CTX and 10−6 M apamin. Relaxations are expressed as per cent decrease in the tension evoked by 10−5 M phenylephrine. *P<0.05, compared with the response to ACh in the absence of drugs.
