Fig. 6From: Anti-aging effect and gene expression profiling of dung beetle glycosaminoglycan in aged ratsEffect of CaG on endothelium-dependent relaxation in isolated aortic rings from normal rat (N = 6). After 1 h-equlibration, aortic rings were treated with vehicle (saline) or Catharsius GAG (10 μg/ml, 100 μg/ml) 10 min before contraction was induced by phenyleprine 1 μM. Then, endothelium-dependent relaxation was induced by acethylcholine (0.1 ~ 100 μM)Back to article page
