Effect of nitric oxide (NO) on dependence and tolerance of normorphine (NM) in the guinea-pig ileum in vitro / 中国药理学通报

0.05. The ratio of NM (200 nmol? L-l) plus NOArg (0.1 mmol. L-1 ) is 0.47 ? 0.05, compared with control (n = 6, P 0 .05). CONCLUSIONS These results suggest that NO has important role on dependence and tolerance of NM in the guinea Pig ileum.
