Objective:: Intimal hyperplasia is associated with graft failure and vascular sutures in the first year after surgery and in postangioplasty restenosis. Allium sativum (common garlic) lowers cholesterol and has antioxidant effects; it also has antiplatelet and antitumor properties and, therefore, has great potential to reduce or inhibit intimal hyperplasia of the arteries. Our objective is to determine if the garlic has an efficacy to inhibit myointimal hyperplasia compared to cilostazol.
Methods:: Female New Zealand rabbits were divided into the following groups (n=10 each) according to treatment: group A, garlic, 800µg×kg-1×day-1, orally; group C, cilostazol, 50 mg.day-1, orally; group PS, 10 ml of 0.9% physiological saline solution, orally. Our primary is the difference of the mean of myointimal hyperplasia. Statistical analysis was performed by using ANOVA and Tukey tests, as well as the Chi-square test. We calculated the 95% confidence interval for each point estimate, and the P value was set as<0.05.
Results:: Group PS had a mean hyperplasia rate of 35.74% (95% CI, 31.76-39.71%); group C, 16.21% (95% CI, 13.36-19.05%); and group A, 21.12% (95% CI, 17.26-25.01%); P<0.0001.
Conclusion:: We conclude that Allium sativum had the same efficacy in inhibiting myointimal hyperplasia when compared to the positive control, cilostazol.
