Effect of Ferula persica plant methanol extract on the level of Cox-2 in induced squamous cell carcinoma (SCC) in rat tongue

Background: More than 90% of oral cancers are cases of squamous cell carcinoma. Standard treatment of cancer includes a combination of surgery, chemotherapy and radiotherapy. Each of these treatments, however, brings about certain problems and side effects. Today herbal medicine, has become a more preferable option in dealing with health problems or preventing them because this type of medicine has better compatibility with the body and does not cause undesirable side effects. In this study , the effect of Ferula persica plant methanol extraction on Cox-2 levels in SCC induced rat tongue is conducted in vivo. Methods: In this lab research, 75 rats from SD race in the age – range of 2/5 – 3 months were selected and put in five groups. In order to induce tongue carcinoma, 4– Nitroquinoline 1 (4 NQO) powder was used 3 times a week for each rat. Furthermore, Ferula persica extract was given to each of the groups in order to examine Cox-2 changes in the blood. Results: Comparison of Cox-2 average in various groups resulted in the observation that there was significant difference between the Cox-2 levels in the groups which had only received carcinogen and the other groups. In this group, Cox-2 level was less and in the group that had received Ferula extract (500 mg) along with carcinogen , Cox-2 level was found to be more than other groups. Conclusion: Ferula persica extract does not have reducing effect on serum Cox-2.
