Figure 2From: Upregulation of cystathionine beta-synthetase expression by nuclear factor-kappa B activation contributes to visceral hypersensitivity in adult rats with neonatal maternal deprivation CBS inhibitor AOAA attenuated AWR scores in NMD rats. (A) CBS inhibitor abolished visceral hyperalgesia induced by NMD in a dose dependent manner. The maximal effect was at 10 mg/kg body weight (i.p.) in this study. n=8 rats for each dose group; *P<0.05. (B) CBS inhibitor mitigated visceral hyperalgesia induced by NMD time-dependently. AOAA-induced antinociceptive effect lasted for about 60 minutes in both 10 and 20 mg/kg body weight. n=8 rats for each group; *P<0.05. (C) AOAA (10 mg/kg body weight) had no effect on AWR scores of age-matched healthy control rats (n=8).Back to article page
