ABSTRACT
This study was designed to determine the protective effect of scopolamine and catalase on the arterial endothelial cells during reoxygenation. The culture of endothelial cells from bovine aorta subjected to ischemia for 2 hours and reoxygenation for 30 minutes was used as a model for inves-tigaion. In the experimental group, scopolamine was added to the arterial endothelial cells culture medium, Hanks solution containing no sugar or oxygen; or in the control group no medicine was added to the ordinary Hanks solution. The alteration of glutathione ( GSH ) and malondialdehyde (MDA) of endothelial cells, and nitric oxide (NO) and lac-tate dehydrogenase (LDH) in the supernatant fluid were determined. The results demonstrated the following changes (1) GSH in the control group significant reduction from the preischemia value 44. 5 + 2.45 to postischemia and reoxy genation value 35.08 + 5.72ug/mg protein, vs the post-ischemia and reoxygenatior value of 46. 67+3.20ug/ mg protein (scopolamine) and 43.38+2.98ug/mg protein (catalase). The differences between the GSH changes of control group and medicine treated group are statistically significant (P
